Re: [O] Near real-time preview of PDF/ODT export?
Hi, just in a coincidence, I looked into Whizzytex [1] a few days ago. This minor mode opens up a pdf-viewer and keeps it updated with literally every keystroke within the tex-file. (Yes xpdf works, albeit the website and emacswiki only describe dvi and ps as backends). In addition, it adds some marks in the PDF to show the actual cursor position wihin the tex-file. You could see it as some sort of pdf-preview on drugs. That is a realtime-update instead of an update after each compilation. WhizzyTex tries to be smart and only seems to compile the region which is needed to give you the output you would like to see. This is very useful esp. if you do small corrections (like revising a manuscript). Since you can see what effect your spellcheck corrections and grammar twisting has on the document outcome. On the other hand, if you receive a hand-annotated version of an manuscript is much easier to find the parts which needs to be corrected having a life-update beside the TeX-file. Another area where I really like it is in conjunction with TikZ. WhizzyTex gives you a online-update of your drawing. As people who worked with TikZ now, it can be very cumbersome to get the right coordinates for something. With WhizzyTex the position of drawings, nodes and whatever, change instantly as you type it. This makes drawing really easy. On the downside, it seems a bit outdated. At least the installer gave me a headache. The manual describes a manual installation method which after some tweaking worked for me. There is no package on ELPA thus, I have no idea about the actual status of it. Last update was on January 2013, not that long ago. Would it be an option to implement something like WhizzyTex for org-mode? Thus you would have the easiness of org-mode syntax (which is enough for many cases) with an realtime update of the export to PDF.

Re: [O] Near real-time preview of PDF/ODT export?
Hi Alan, nice, you might can start easily asking him to solve the installer problem and provide an package for a ELPA repository. That alone would allow much more people to use it. I think the main problem for org-mode would be the fact that org-mode-PDF is a two step approach. Org-mode exports converts the org-mode syntax into a TeX file which then gets compiled into PDF by a LaTeX system. To preserve the cursor position, the org-mode exporter would have to add the necessary code already within the Tex-file. That means whatever whizzytex.el is doing to the final latex code, parts of it would need to move to org-mode export for PDF. After that, I believe one could use whizzytex as it is. However, I guess the author Didier Rémy can forsee already very clearly what kind of feature would be needed in the org-mode exporter to make it working with whizzytex. Since we have now a modular exporting system, we could have a ox-whizzytex which mainly base on ox-latex and only adds the additional requirements for whizzytex. this requirements as far as I can see would be: 1. Cursor position 2. Automatic definition of an export region (in the same way, Whizzytex works on a subset of the TeX-buffer to allow fast compilation). 3. Create a function outside the exporter which calls ox-whizzytex exporter for each change in the org-file. Point 2 would be necessary within org-export to avoid long processing times of org-export on large documents. All in all, it would require to implement the functions defined in whizzytex.el to org-mode resp. the org-exporter. Alternatively, one could make whizzytex aware of org-mode and calling the org-exporter for an region first before processing the generated TeX file. This would lead to the decision whether to have a org-mode exporter for whizzytex or to make whizzytex aware of org-mode All the best Torsten On 25 November 2013 11:35, Alan Schmitt alan.schm...@polytechnique.org wrote: Hello, torsten.wag...@gmail.com writes: Would it be an option to implement something like WhizzyTex for org-mode?

Re: [O] Drag images from Firefox to org-mode
Hi, I have to correct myself, I could use the link created by thunderbird drag and drop. I simply missed to put the link into quotes. This works, thunderbird will open the message in a new view. thunderbird -mails imap://user.name%2borganisation@mailsystem.organisation.com:993/fetchUID/INBOX1274 However, the drawback with this, the url is rather fragile. It relies on the folder and a simple number. I am not sure how much one could rely that this number is always the same. Maybe imap or thunderbird compress the list of emails by time effectively renumbering each email in a folder. Furthermore, if I move the mail to another folder my org-mode link would be broken too. Thunderlink (a thunderbird plugin), instead is able to fetch the message-id, which is unique and independent on the mail position. If there is an interest to extend the drag and drop to emails, I could ask the developer of thunderlink if there is a way to change the drag and drop url to the message-id e.g. with the help of his plugin. Thunderlink itself works already quite well with org-mode. The newest version on git-hub allows to create direct org-mode links which one could simply copy and paste from the clipboard. Guess only a small amount of work would be needed to make it drag and drop ready too. One could also think of saving the email as plain text in the org-mode folder and create a link to that. However, I frighten this would require more work. One idea would be to fetch the email by the message id from the imap server from within emacs. But I guess this would create a large amount of dependencies to make this working.

Re: [O] [RFC] Change some defcustoms into defcont
Hi, not being a dev and really not being a lisp programmer, I still can see Nicolas attempt to unify the syntax in a way all and everyone/everything can rely on it. The question would be what would be more troublesome? Dealing in future with people who by chance changed some of those variables and who suddenly face problems using third party (internal as well as external) tools. E.g., tools like org-ruby came to my mind. More and more projects start to include org-syntax too. For all those it would become difficult to rely on certain keywords. Or is it more problematic that those who changed variables already, might find there system broken / in need of manual adoption after an update? Anyhow, I just had this idea that org-mode could rely on a fixed (as written in stone) set of keywords and that an a new exporter backend will be introduced which simply creates a standard-conform org-mode file. Let's call it ox-legacy ;) Those created files could be send to others to work on it or could be used in conjunction with 3rd party programs. By time, one could think of a org-mode import, which again takes a standard conform org-mode file and translates it back into the individual settings of a specific user. Having an legacy org-mode exporter and importer, could even allow to customize org-mode for different languages, e.g. one could set (setq org-mode-language german) to get a set of keywords in German. Exporting it into legacy org-mode would translate it back into e.g. English, which then again could be read-in by a user who set (setq org-mode-language japanese) and who would be able to read the file with a set of Japanese keywords. Just an idea I had following this thread.

You can modify a defconst, but the strong message is you are not supposed to do that. I didn't suggest modifying these variables was expected. Anyway, I acknowledge I wasn't very clear. Yes, sorry. By nothing I mean nothing we cannot achieve with documentation and a :set method. This will not fix the bug. Hi Nicolas, can you remind me what the bug was? The taskjuggler issue? Since we will still rely on the variables, the advantage for maintenance is something I do not see. As a developer, you have to keep in mind that the string might be changed. Sometimes, it's easy to forget you cannot hardcode it, e.g. when writing a search regexp. I have done a similar mistake in ox-taskjuggler.el, where I expect the effort property to be named :EFFORT:. More things to remember, more potential bugs, more maintenance efforts. Cache friendliness I see, but I would think that if someone changes these variables, they will not keep changing them. Of course. I shouldn't have talked about cache since it makes me sound like a lazy person. I can work around the cache problem. Again my main concern was to move to a proper, Emacs-independent, /minimal/ core syntax, i.e., to define the Org format. For example, at the moment, external tools cannot rely on SCHEDULED: string to write even a basic Org file, because SCHEDULED: doesn't clearly belong to the syntax and, therefore, might be incompatible with some configurations. Yes, as I said, I do see all these problems, but I also feel the responsibility to break as few as possible existing configurations. If you want, I can take a shot at documenting this properly. - Carsten Regards, -- Nicolas Goaziou
Re: [O] org-mode based groupware wiki
Dear Wally, Dear Eric, thanks for the replies and sorry for the long delay. Interesting that there is an update on org-ruby just in the middle of my decision pathway ;). Until know I thought org-ruby is pretty much orphaned and that by time it will start to fail on the growing changes done in org-mode. On the other hand with all the help on the list I got org-ehtml working now. It was indeed a missing requirement call (require 'assoc) did the job. Now I was able to test both gollumn and org-ehtml it puts me into a dilemma. From user (esp. non-org-user) perspective gollumn seems much more attractive. The editor is more user friendly for non-orgers and the integrated git versioning is working pretty stable. Gollumn itself seems to run on the shoulder of giants and keep itself rather small. Overall, a quite positive impression. However, it depends on the org-ruby package, which still understand only a subset of org-modes features. It seems to me somehow a hunting task to keep track with the fast pace of the org-mode development. This does not only include new features but also slight differences between the original org-mode export and the org-ruby parsing. It might be as simple as an extra blank here or there, which can be quite troublesome form time to time. e-html works great too. It is somehow a little bit more a web-based editable org-mode, whereas gollumn is a wiki-system which supports org-mode. org-html would do a perfect job for myself if I am the only user for this wiki. However, I frighten that non-orgers have a harder time to use it compare to gollumn. For some reason which I can't explain, I feel a bit nervous about running an emacs session continuously on my server to provide a website. Not sure where the fear comes from. Maybe it is just because of my bad elisp skills ;) Overall, it works now and it does a good job but I can't avoid the feeling that all of it might be a bit fragile (as it might brake on arbitrarily changes on elnode, emacs, org-mode). However, it has the great benefit to be 100% up-to-date with whatever org-mode supports now or in the future and the output of a static page would be the same as the dynamic page. I even could create PDF versions if needed e.g. for static archiving. I do not exactly now the intentions for org-ruby. Maybe Wally like to elaborate on this. Maybe org-ruby can catch up faster with the new exporter features of org-mode now that org-mode gets a more standardized syntax. At the moment, for me the best would be to combine both worlds somehow. I notice that gollum allows to define/call new parsers. Would it be possible to call emacs and start and html export on changes saved in the webbrowser? In other words why not calling emacs directly to do the html export? I would assume that the code which has to be added to gollum would be minimal and the same would be true for the few lines of lisp code to create the html page. That would allow me to use the non-orger friendly gollumn and get the same accurate result as I do with org-ehtml. However, it would only call emacs from time to time instead of a constant emacs session running. Maybe this (sorry) very long mail helps me to get the best of both worlds ;) Thanks for help and support Torsten On 16 October 2013 19:52, Waldemar Quevedo waldemar.quev...@gmail.com wrote: Hello Torsten, - Enhance org-ruby?

Re: [O] org-mode based groupware wiki
Dear Eric, thanks for the reply. Now I was able to test both gollumn and org-ehtml it puts me into a dilemma. Multiple viable options for Org-mode wikis is a great problem to have. Indeed it is as usual with FOSS all those pesty options to choice from. Why couldn't I just trough my money to multi-billion dollar companies and use whatever the selling department thought would be best for me. Silly me ;) See the Integrating with version control section of the org-ehtml README [1]. It provides VC integration with just a couple of lines of Emacs Lisp which could be added to the webserver's Emacs config. I didn't test this yet, but read about it. I will give it a try again. Gollumn itself seems to run on the shoulder of giants and keep itself rather small. Org-ehtml is itself just a tiny hack which (I think) neatly combines the power of the new Org export system, and the power of Elnode running on top of a full fledged Emacs instance. Org-ehtml is more than two orders of magnitude smaller than gollum (judging by compressed source code). Well indeed this was a stupid comparison. Sure org-ehtml is even smaller and stands on the shoulder giants too, namely of org-mode and emacs Understood. I hope I haven't wasted your time and I appreciated that you got org-ehtml running. Gollum is a very mature option, and is probably your best bet unless you fall into one of the following. Wasted my time?! ;) Are you kidding me. It was very informative and fun. Seriously, I always enjoy having org-babel or in this case e-html related problems, just for the joy I have to talk too you ;) There is still no decision made yet and I guess it is even not a time critical decision. Since both systems use org-mode files I could easily switch between them any time later. 1. need more esoteric features of Org-mode or I frighten looking at the feature test from Karl Voit (https://github.com/novoid/github-orgmode-tests), the features need not to be sooo esoteric at all. 2. you like the idea of being able to run arbitrary Emacs Lisp as part of the editing process or Yes you are right, thinking about, the advantage would be that I could use all org-mode related code and do not need to reimplement it in any other language. E.g., one could get a pretty printed table in text form easily calling org-table-align, or convert copy and pasted CSV data into a table calling org-table-convert. However, that would require an extension of the current web-based editor. 3. (like me) you don't have ruby installed on your system and a ruby web server seems like a lot of bloat for a wiki Here I would need to give gollumn the credit that you can use another web server as well e.g. apache should work. The reason Gollum is so much larger is because it has a large team of people adding the many handlers for edge cases and extra bells and whistles which make for a robust tool. Sure, and please understand that I do not want to compare them one-by-one. It wasn't my intention to do any ranking. Just looking for the best solution for my task. If a 5-liner bash script from 1995 could do what I want I would be equally happy too ;) My goal with org-ehtml was to produce a tiny working and (most importantly) easily hackable core. I don't have time to really flesh it out myself, but I was/am hoping that someone interested in doing some elisp and web programming would/will find it fun to extend the existing proof-of-concept implementation. I think it could easily grow into a full featured Org-mode backed wiki, or online TODO tracker, or online bug tracking database. I understand and I would be happy to be part of it. I simply need to test a bit more which way to go. I like the idea to use emacs and the real exporter. Just need to think of the non-orgers... For speed reasons you'd probably still want the constant Emacs session running, and you may open up many of the same security concerns. Yep, I was thinking about that and thought already about a emacs daemon running. You are right, that might put me into the same situation I have using org-ehtml directly. Would it be possible/reasonable to create something which use e.g. apache or lighthttpd as webbrowser and some javascript to implement the editor functions and emacs+org-mode purely to generate the html pages? Using a well established webserver, would give me at least the illusion that it might be safer. There are some editors implemented in javascript already. Maybe one could use one of them? I think it all condense down to the phrase I gave in my early post: org-ehtml: org-mode with editable html export and a minimal webserver gollumn: ruby-based wiki-system which supports (partially) org-mode syntax Both are very different concepts with a different idea behind it.

If it works ok for you with the recent version of elnode and ehtml, I might have to digg where my config is broken. I tried following the readmes but the elnode server responeses with h1Server error/h1 at the website and I can't find any addtional error message in the logs.

Checking why I do not have the latest and finest version of org-ehtml I found the following error package-compute-transaction: Need package `elnode-20130416.1626', but only 0.9.9.7.6 is available However, org-ehtml requirements in ELPA says Requires: elnode-0.9.9, org-plus-contrib-20120928 I can't find a version of ELPA with this name.

[O] org-mode based groupware wiki
Hi, recently I discovered gollumn [1] and was amazed to see that there is a software which allows non-orgers to work with / read my org-files and which even use git as the backend to get all save and nice together, even if working concurrently on the same files. I was wondering, because I never read about gollum in this ML and my search only revealed a very short three year old thread between Bastien and Eric Schulte. Despite that many of us was asking of possible ways how to use org as a groupware like environment. I guess this topic was discussed even more frequently over the last three years. Unfortunately, the main drawback, the usage of org-ruby [2] as org-mode parser still remains. I frighten that org-ruby only works on a small subset of the org-mode syntax and that even this might be a bit out-of-date. As far as I understood, org-mode in the meantime switched to a new exporter [3] and we got org-elements [4] and a heavy work towards standardization thanks to Nicolas Goaziou. What would be the best way to get the best out of the gollum idea and the new org-mode capabilities? - Skip gollumn and use (an updated) blorgit [5] (Does it have editor functionality?) ? - Enhance org-ruby? - Write a small script which creates a native html export from org-mode and hook this into gollumn? However, that would require emacs and org-mode being installed on the server side. For me gollums most important feature would be that people could use their web-browser and edit org-files. It might not be the most comfortable way of editing a org-file but a simple adding of a row into a table or rephrasing or adding a paragraph would be totally possible. It even might help to introduce people into using emacs and org-mode. It would be really nice to have such an easy access to org-files. Even hard-core orgers might like the idea to e.g. access and lightly modify there org-files on-the-go via smartphones and tablets without running a full emacs session. (I am aware of Mobileorg ;) ) I got a bit into detail here to hopefully kick-off some discussions.

Hi Carsten, just by chance I read this thread. It might be a good idea to announce this somehow for package maintainers on a prominent place in the change-log of the next official release. Some Linux package systems do allow recommendation on packages. As I understood the xdg-utils package is not mandatory for using org-mode, because it would work without xdg-open too. However, we could ask the package maintainers to make a recommendation to install xdg-util whenever, org-mode gets installed. Just a nice customer service ;) BTW: Emacs itself does *not* require xdg-utils or refer to it as optional. That would have made it even easier to assume it is already on all Linux systems.

[O] Generate and fill PDF-forms by org-mode?!
Hi, recently (well not so recently unfortunately) I have to deal with a lot of forms. forms forms forms... always almost the same, always almost boring. I was wondering, can I teach org-mode to do this for me? Ideally, I will use a org-table or org-properties, and execute e.g. a babel src-code block which in turn will take all this properties and fill it into a certain form and generate a PDF, send it to printer to let it me sign and hand it over. Hence I could keep all the important infos of a task in org-mode and automatically generate necessary forms as requires. E.g. lets take a order-form I could keep company address, items, price, amount, as well as internal project numbers, etc. in a single org-node or possibly take it from different org-tables, org-nodes, org-files, etc. and compose a form with all this data. If the delivery address change, I only have to change it once and the next forms will automatically contain the new address. Did someone try something like this already. Ideally, a ODT-export would be nice too, but I guess even harder to achieve. Another problem I might have to deal with, is how flexible is the administration. They might require to use only there templates (doc and PDF forms). However, the PDF forms are owner secured and hence I do not have a way to extract the FDF infos to interact in some way with them. Does someone know how to fill a PDF form programmatically and if this could be done within org-mode? Any idea how to deal with that would be nice. All the best Torsten

[O] [babel] transfer a list of tables to a source code block
Hi, I have a few functions defined with babel, which need to work on an list of tables. At the moment I use something like :var table1=name1 :var table2=name2 etc. As you can see this is rather inflexible. I am looking for a way to receive a list of tables, whereas table[0] would refer to the first table, etc. Does someone know how to achieve this? To make the best use of both worlds, I thought it would be nice to define a list which contains the names of the tables and somehow manage to access the tables from this list. #+NAME: listoftables - name1 - name2 - name3 #+CALL: myfunction(lst=listoftables) I tried to play around with this idea but did not get a solution yet For the moment I receive the names of the tables only as a string and search for ways to actually transfer the table itself. Thanks for ideas and thoughts... Torsten
Re: [O] [babel] Table as varaiables a differently proccesed by #+call lines vs. source code blocks
Hi Rick, Hi Sebastien, thanks for your inputs. Well I guess Sebastien is half-right. The different settings make at least it even more tricky to see what is going on. Here is a table with the settings as I found them on my system (which I did not change) #+BEGIN_ORG | org-babel-default-header-args| ((:session . none) (:results . replace) (:exports . code) (:cache . no) (:noweb . no) (:hlines . no) (:tangle . no) (:padnewline . yes)) | | org-babel-default-lob-header-args| ((:exports . results)) | | org-babel-default-inline-header-args | ((:session . none)(:results . replace)(:exports . results)) | #+END_ORG As you can see the most prominent cause for trouble might be :hlines As Rick should in his message it does still not solve all problems but it helps to make it more clear. I assume Eric is on holiday or otherwise busy but I guess he will find this thread and might can give us some idea, whether there was an intention in dealing with tables in that way or whether it is really considered as a bug. However, Sebastian pointed out a very important fact. Different default settings for different ways of calling a source code block. I believe that this should find its way into the manual.

Re: [O] #+header keywords for #+call keyword?
Dear Dieter Wilhelm, I do not know a way to change the standard properties for a #+CALL construct. However, we recently discussed a problems with tables and source code calls. Sebastien pointed to the following variables. org-babel-default-header-args ((:session . none) (:results . replace) (:exports . code) (:cache . no) (:noweb . no) (:hlines . no) (:tangle . no) (:padnewline . yes)) org-babel-default-lob-header-args ((:exports . results)) org-babel-default-inline-header-args ((:session . none)(:results . replace)(:exports . results)) You might want to change org-babel-default-lob-header-args to your needs. That could be done in a small eslip code block within an org-file and might at least helps as a intermediate solution All the best Torsten On 24 July 2013 14:11, Dieter Wilhelm, H. die...@duenenhof-wilhelm.dewrote: Dear (), I've got a rather long argument list and it doesn't look good to supply all the arguments in one line, could somebody please implement #+header arguments for #+call like in the following example? #+header: :var NO=(org-entry-get nil Report_Dir) #+header: :var DIR=(org-attach-dir) #+call: ProvideReport()[:results silent] By the way, is it still true that the number of #+header keywords for code blocks is restricted to 5 #+header lines?

Re: [O] [babel] Problems assigning tables as variables using #+CALL and using properties in code blocks and sbe calls
Hi Eric, thanks you so much for always being so responsive to my silly questions :) I apologize, I wrote that mail 2 am after fiddling around with that problem for about 3 hours. Trying to reduce the problem to a minimal example, I almost built in stupid errors. I was holding back to send examples as org-file attachment because I believe that attachments can't be parsed by the different mailing list archives and thus, any infos there are not searchable. However, I guess in the future I will simple paste the example and attach a org-file (which in turn I can really test before sending). Ok back on track. My problem seems to be quite strange.

Re: [O] [bug?] Copy content from one to another table changes the content
Hi again, I think I got a bit more of an idea what is going wrong thanks to Nick. I use $1 = remote(prf94120_orig, @@#$6) which reads copy from table prf94120_orig row (@) of the current to be processed field (@#) column ($) 6 into column ($) 1. The org-mode manual refers to @# as operator for formulas and hence I believe the result will be parsed by calc to get a meaningful output. That is ok for simple strings without space or comma separators, since they remain strings. However, a string like text,text will be send to calc as (text,text) which is the calc notation for imaginary numbers. Either, I should use a different way to copy the column or this could be considered as a bug?! Actually, I still do not understand the need to let calc parse that a field-content. If I want to do math, I am not suppose to express this explicit by my formula? Instead of having a single field content of 1 + 2 evaluated to be 3 by remote copy, I would expect to do something like remote(NAME, REF) + remote(NAME, REF) for calculating the sum of two remote fields or in case I really have a complete expression in a single field, I would expect to do something like (calc remote(NAME, REF)) explicit to get it parsed by calc and placing the result in the new table?! Somehow, I miss something. Would be glad if someone could explain to me the reason for the original behaviour.

Re: [O] execute sbe macro fails
Dear Eric, thanks a lot. That was really insightful. I didn't use babel for several month and I always struggle to get into it again. I clearly was confused about the variable definition. Using a function like I did, one has to do it basically twice, once for babel and once for the target language. I never used the sbe-macro (Actually, I was not even aware of it). Thus, I thought the problem was somehow there. Furthermore, I missed that I should at least call the function once ;) Would it be possible that the error-message contains more infos? E.g. some hints within the mini-buffer or *Messages*-buffer. That would make it easier to debug what is going wrong. Thanks again, that was really helpful.

[O] copy entire column of one table into another
Hi again, I was wondering, is there a way to copy the entire column of one table into another possibly adding rows to the target table to make it fit? I know I can use $1=remote(original, @@#$6) to copy row 6 into row 1 (albeit I did not yet fully understand the @@# part) However, I would to take care that the target table has the same amount of rows as the host table. I work with many tables at the moment and frighten I might overlook a row soon or later. Thus, I would prefer a way to say... copy column of table X into table Y. If table Y has to less rows, add blanks rows until all rows of table X are copied. Any chance to get this working? Thanks for help and ideas Torsten
[O] org-mode as meta-system to create exams?!
Hi, I need a system which can deal with about 100-150 written exams/semester. I was wondering if org-mode can be used to do that. What I want: * Creating exams sheets (technical exams at university level, pictures, equations, large exercises with subitems) * Help for exam evaluation * Scoring system * Mark system * Creation of result sheets and diagrams * Creation of solution sheets I would be glad if I can create a little automation into this, to help me with the amount of exams. E.g. scoring could result in marking according to a translate table, Exam sheets should allow easy evaluation e.g. students fill answers in allocated spaces, there are places to write down scores, etc. Other details would be nice to have but not yet important. E.g. I like the idea that name and ID number of students are written on the top right corner of the sheet which gets wrapped (and stapled) thus, evaluation happens complete anonymous. Definition of an evaluation sheet, which precisely describes which results return how many scores, etc. Would love to hear how other use org-mode to deal with that task. Alternatively, if you use or would use another software please let me know. Thanks Torsten
Re: [O] [Feature Request] - Furigana - Yomigana - Ruby
Hi Tristan,
this feature request seems simple to implement on one side. However, it
opens a question how to deal with those in general.
\ruby{東} is a very specific command of the CJK package.
If this get's implemented in the standard html exporter, other very special
commands might need to follow. That could easily go into a nightmare. I do
not have a detailed view how the exporters work now, thus, it is a
interesting question I want to ask here: How should specific needs for
exporting (like Tristans) be embedded in the future.
People could fork exporters. Creating e.g. a HTML-CJK exporter.
Even better would be to have exporter modules which could be loaded by
users.
#+HTML_MODULES CJK,
However, I believe that for many users, the special cases are not very
frequent and complex. Might it be possible to create a very simple syntax
for exporting rules which could be either in those above modules or
directly within the file written by the user themself?
#+HTML_USER_RULE \ruby{$1}{$2}, ruby $1 rp(/rprt$2/rtrp)/rp
\ruby
Would like to hear what other think about that.
Greetings

Hi,

I would like to use orgmode to capture japanese text to later export to

For japanese symbols, sometimes the pronounciation is put in smaller

also called furigana/yomigana, which I put in the header so not everybody
thinks of the programming language..)

as:
ruby symbol rp(/rprtreading/rtrp**)/rp \ruby
as suggested here, for parentheses on non-ruby supporting browsers:
http://xahlee.info/js/html5_**ruby_tag.htmlhttp://xahlee.info/js/html5_ruby_tag.html
For the org-mode file (you might see some blank squares if you have no
japanese support):

#+LATEX_HEADER: \usepackage{CJK} \end{CJK}
#+LATEX \begin{CJK}{UTF8}{min}
\ruby{東}{ひがし}アジア means east asia in japanese

Re: [O] Enriched/Org is a colorful Org
Hi, just want to add some observation. I guess it has nothing to do with the display engine but it might be somehow related. I used to use line-mode to display line-numbers as a left column on all my buffers. I noticed a very painful slowdown up to a totally unusable state during working on very large org-files. It consisted of coursework for a programming class and contained single headers with the student-id numbers and a babel-code block in the headers body (hence, easily goes into 1000th of lines). I was happy with it since I could execute and proof each submitted coursework within a single org-file and folding helped me to move quickly from one to the other coursework. However, as longer as the list get as more it slowed down. After some fiddling and searching, I noticed that the line-mode was kind of struggling with the org-mode text-collapse feature. Whenever, I closed a header, it took large amount of times to recalculate the line-numbers. Not sure where exactly line-mode did consume the time. But it might as well be related to the redisplaying of the numbers. Switching off the line-mode made the time delay disappear completely. Just an observation which might or might not related to the later discussion.

My Sunday pleasure reading project. Good luck, and let me know if you need something explained. The commentary at the beginning of the file might serve as an introduction, although it doesn't really touch the issue at hand. So the reason that the combination with hi-line is slow is because hl-line is using post-command-hook to move its overlay, and redisplay of a full window with org-mode is slow because so much stuff is hidden and Emacs makes a full re-evaluation of what needs to be displayed? Right. If hi-line (or any similar mode) is off, then at least horizontal cursor motion should be fast, because then Emacs knows that nothing changed, and finding the place where to put the cursor on the same line it was before is relatively easy. But even C-n and C-p is quite another story in an Org buffer: Emacs needs to determine where that puts point, and doing so generally means traversing all of the hidden parts of the buffer between the line which was current and the new current line. In a complex Org buffer, that could easily be many thousands of buffer positions. I guess outline mode does have the exact same problem in this case, in fact any mode with large amount of hidden text. Also, recall that, under line-move-visual, which is nowadays on by default, Not in my setup, but since it the default, yes, this causes more issues. Another important point to be aware of. Emacs moves by _screen_ lines, not by physical lines. So a simple C-n must internally emulate display to find the next line visible on the screen by traversing the buffer one character at a time and taking note of each and every text property and overlay in between, until it finds the buffer position whose screen coordinates are [X,Y+N], where [X,Y] are the coordinates of the previous cursor position and N is the line height in pixels. And this is just to find where point will be; then the screen must actually be redisplayed, which might mean more work, if the new position of point requires scrolling, e.g. if cursor went off the scroll margins or whatever. We only get reasonably fast performance with all this complexity because our machines are incredibly fast. But we are many times on the edge, as the bug I cited and similar ones show. Thanks again. - Carsten

Re: [O] Google calendar sync - what is recommended?
Hi Rainer, I have to agree with Rasmus, the question is, do you really want to sync to google calendar or do you want to sync your smartphone calendar (most likely an Android-based phone) with org-mode? In case of the last, you might omit using google calendar completely and use another service with caldav support. If you have access to an own server (a PC which can be reached from the internet), you might be able to even install your own solution. There is an android app [1] which allows syncing of caldav-servers with the Android calendar in the same way like the google calendar (in the background, without any user-interaction after initial set-up). Unfortunately, it is not free, but I would say it is worth the money. E.g. I use SOGo + org-caldav + CalDAV-Sync to sync between my Android-based phone, a web-based calendar and org-mode. Works great. BTW. There is another Android app (CardDAV), which does the same for your address book.

Re: [O] Where does org-mode elisp hacking go?
Hi Eric, sorry for the last two spams. Believe it or not, I fell asleep last night, during typing an answer and somehow managed to send twice a message ;) People should not take there smartphones to bed. Sounds dangerous to me. I often place init.el files into sub-directories which require project specific customization. You may also want to look at (info (elisp)Directory Local Variables) for adding setting based on the working directory. Why does this sound dangerous. Encrypted babel blocks could not be modified and even not been read without user authentication. Furthermore, even if I use a org-file from someone else, I would have to authorize the execution by decryption of the block. Thus, its unlikely someone executes something by accident. Beside of the autostart, encrypted source code blocks might make sens too, if sensitive data might be part of the block. E.g. username and login credentials to login into a certain service. I do not want to hijack this thread. It was just an idea which sounded to me rather easy to implement, since the core features are all there already. Feel free, to set it on the crazy ideas list, if you feel that it is not a good idea ;) All the best Torsten

Re: [O] Where does org-mode elisp hacking go?
Hi, if I have a project based on org which require some special settings (not only in lisp) I use a babel block and execute it after loading the file. I did this e.g. to set my Java environment correct If I remember correctly, we discussed once an autoload feature for org-babel, but security concerns overruled that idea. If some autoload feature should ever land in the repro, one would have to make sure that the code can't be manipulated e.g. by an external editor. This would come close to creating org-babel-viruses ;) One possible idea which jumps just to my mind, how about a combination of a babel blocks and org-encrypt? Encrypted babel blocks with a certain tag could be considered save for execution immediately after the user authentication during loading a certain buffer. I guess most of the functionality (tag, encryption, block-execution) is there already, it just would need some glue to put it together and a hook into opening of org-mode files Hmmm. I think I put Eric CC :) Other then this I have a .init.el which simply loads many other lisp files, one of them is init_org.el If you frighten that emacs start-up might be to much delayed you might want to check the daemon / emcasclient feature of emacs.

Hi David, first of all thanks again for your great contribution. Maybe this is a good time to announce that we use org-caldav since several weeks together with SoGO. SoGO does allow syncing of Android devices too (via an App). It syncs full automatically with the Android calendar! It comes with a nice web-based calendar (better then what Google offers IMHO) It syncs with Thunderbird/Lightning. I never tested but they claim iphone and Outlook support as well. You can host your SoGO instance on your own server. On top SoGO offers address-book and email capabilities (both syncing and web-apps). There are minor problems (on the SoGO side) but overall its running perfectly stable for us.

Re: [O] Create course material with org-mode
Hi Brian, Hi Torsten, I thought I'd muddy your waters by throwing a contrary voice into the mix :-) N do not destroy my view of a perfect world ;) I've been refining the way I manage my college and uni teaching with org for 5+ years, now. I am making extensive use of the scheduling and TODO functionality. I am not storing course materials in the org files. I found that I could not get by with just one teaching.org file, but instead needed to break out each class into its own org file. With everything in one, even on my pretty beefy box (quad core i7, 8GB RAM) there was too much of a periodic lag when editing the org file for that to be comfortable. On my netbook (which I take to the office as the College insists I need a Windows box on my desk), the lag made working with the file far too painful. I've not tried putting my (extensive) LaTeX beamer slides sources, exams, etc. into the org files, but I fear the lag would again occur. Actually, that might be misunderstood. My aim is not to create a teaching.org file but many org-files, one for each topic. I totally agree a single org-mode file for an entire course would be really fast difficult to maintain. A complete course might consist of many org-files. Splitting the entire lecture in a similar way like an ordinary table of content. However, I would love to keep all infos of a certain topic within a single org-mode file together. Slides, lecture notes, exam questions, exercises, organisation, TODOs, ideas, maybe code, etc. I've been keeping all course related material other than the org files which manage scheduling into a seperate directory under git version control and I link from the org file's scheduled tasks to the relevant course related materials. It seems to be working in that I am halfway through the term and am at most a week behind :-) Having those materials in nested dirs in the filesystem is helpful, too; it allows granular use of things like $git log . and that often gives me a better sense of what I've been up to than would running git log against one monster all in org file. GIT will be definitely part of my toolchain independent of the usage of org-mode. I don't however too much by way of multiple outputs derived from common sources. I let LaTeX beamer's facilities take care of prodicing a display and a downloadable version of my slides. That just needs two short master files which \include the body of the slides. What duplication I have is in things like tests and paper topics when I have multiple sections of the same course in a term, differing only in section numbers and dates. The duplication is a bit inellegant, but it is not extensive enough for me to worry about the overhead of avoiding it. And, disk space is approximately free, at least if one is worried about having duplicates of latex sources that generate a few pages. Actually, that is exactly what I am trying to figure out at the moment. How to generate a entire script or lecture slides from different org-mode files which contain not only one sort buy many different sorts of information. Thanks for the input, I guess we are more on the the same path rather then contrary. ;) Best Torsten
Re: [O] Create course material with org-mode
Hi Thorsten, thanks for the links. I will look into them. Actually the topic is not exactly OT, I'm looking for a meta-system which helps me to keep all those different things together. Hopefully, in a way which allows me to generate different kind of course material from the same sources. I was wondering, can org-mode be such a meta-system e.g. could I keep materials of a certain topic within a single org-file and use (customized) exporters to create the desired outputs like a interactive HTML version, a printable PDF, exercises and questions for exams? E.g. a file structure like this * Theory text text text ** Interactive example :HTML Bable code ** more theory in detail *** Images ** lecture slides :BEAMER ** Exercises *** Solutions ** Exam questions *** 1 *** 2 *** 3 This file should ideally run through different exporters to generate interactive HTML for a website, printable PDF version, slides for a lecture, exercises with and without solution, exam questions, One task which might require some more attention (and code) would be to compile e.g. the entire script from different source files. Same for an entire exam, a set of exercise, etc. The benefit of an approach like above would be that I can keep all related infos close to each other. It would be much easier to make changes among all different outputs, create new material, etc. Hope this makes my idea more clear.

[O] Create course material with org-mode
Hi, I plan to create new course materials for teaching at university level. These materials should contain - a printable course script - an interactive web-course - lecture slides - exercises - exams I'm looking for a system which enables me to keep all materials together and to reuse as much as possible the same source files. E.g., for a particular topic, I would love to create all the above materials within a single file. This would help me to keep it among all materials coherent, correct errors and do updates effectively and save (hopefully) a lot of time. I was looking into different directions like using HTML5, LaTeX, etc. However, I didn't find a perfect solution yet. I know many of you do similar work and hence, I really would love to hear about any ideas, tricks, systems or solutions. Furthermore, I wonder how much I could use org-mode (to make this thread not off-topic ;)) to solve the above task. Thanks Torsten
Re: [O] org-caldav can't find org-prepare-agenda-buffers
Hi David, Well it would be a temporary solution for two reasons. 1. New emacs releases would come with the new org-files. 2. All third-party code might by time move to the new files. Thus, I thought this is a (maybe on a long perspective) temporary solution. Other non-unix like OSes: In that case, a small wrapper file, which replaces the old files might be the best solution, since it would work under all OSes. This wrapper could call the right functions within the new file and issues a warning/error/log that the call is deprecated. Hence it gives third-party maintainers (or anyone who jumps in) enough time to change the code.

Re: [O] Add agenda entries into diary to export weelky calendar
Hi Sakurai san, I gave calfw a new try yesterday. It works well now and I really like it! I tried to do, as you suggested, a export via htmlfontify-buffer. It seems like it has problems with the cell alignment for those cells which contain an appointment. Please see the attached picture (I can send you the html file in a private mail if you are interested to see the html code). Could be the trouble of a non-monospace font, As far as I know Japanese fonts are monospace? The generic htmlfontify-buffer might be a bit to simple. E.g. as you can see in the image, I use a dark colour scheme in emacs. This is also used in the export, making it difficult to print. How about a real export function in calfw? Similar to what the calendar/diary offers. I could help to work on a LaTeX template using graphical elements e.g. by using TikZ [1]. There are SVG-based generators and solutions written in python as well. However, I have no idea how move the data of calfw into a template or into such a script. My elisp knowledge is almost non existing.

Re: [O] Add agenda entries into diary to export weelky calendar
Hi Eric, thanks for the tip. I tried this already. Its printing but has some drawbacks. E.g. I use high resolution monitors in vertical (pivot) mode and a tiling window manager. calfw scales to the current buffer size and this is unfortunately not really compatible with printing. In summary this solution might have to many ways to go wrong. However, I noticed a much more interesting way. calfw buffer look almost like org-tables. And voila saving the buffer as org-file and a minimum of modifications allows me to export the calendar with both the html and pdf exporter. I just try to tell org-mode/latex/html to keep the height of the rows constant and independent of the content of the cell. Guess if I get this right, everything could be done in a little piece of elisp. Alternatively, Sakurai san may like to create an official cfw:export-view-to-org could be part of calfw-org. This would also allow people to archive calendar views in org-mode files. Lets see how this is going.

Re: [O] Add agenda entries into diary to export weelky calendar
Hi Sakurai san, CC: Hi David, thanks a lot for the offer, I would need to check what was the specific problem. Indeed I would love to use calfw if it can produce a printable version. Did you think about a PDF export via LaTeX? I would be glad to help with this. Actually, my idea was to get a print-out calendar of the past last week, the current week and the next 2-3 weeks on a single double sided page. I would print and fold this every week once, carry it around in my money-wallet doing good old paper-pen organisation and transfer all the handwritten stuff into org-mode as soon as I am sitting in front of my PC. Furthermore, I would like to scan and file those printouts for archiving purpose. Finally, you might like to get in contact with the author of org-caldav David Engster (I was so free to CC him this mail). Since he should have a pretty good idea of caldav on emacs, it might be possible to use calfw as caldav-client. This would allow to subscribe to calendars for public holiday or of co-workers which do not use emacs. If I understood calfw internal structure right, it would just require a calfw-caldav.el extension. I can see a lot of great synergetical effects for both projects and would be glad if this stipulates both of you to think of e.g. certain hooks to let both projects work seamlessly together. E.g. calfw could be the frontend for a merge function of org-caldav showing conflicting appointments. Thanks a lot for the great projects. ども ありがと ございます.

[O] Add agenda entries into diary to export weelky calendar
Hi, still trying to get a printed calendar including all org-agendas, I noticed that the calendar/diary built-in function in emacs allows export of calendar views. Guess that and some post-processing for the print-job is all I need. However, I did not find a way how-to add org-agenda entries into the diary resp. into the calendar export. I know it works vice versa, seeing diary entries in org-agenda views. Did someone manage to achieve this. Alternatively, would it be of interest (and how difficult would it be) to get org-agenda exports as daily/weekly/monthly calendar as PDF (via LaTeX) or HTML? Guess to start this one would have to look into the new exporter functions and create a list of all agenda entries feeding this into a template. However, most of the functionality is already there via calendar/diary and I wonder which way would be the best; using those functions or create own. Alternatives: I read about calfw and org2hpda.

Re: [O] org-caldav feedback
Hi Eric, If I understood David right, the UTC option is just an addition to the already present options. Thus, if you used e.g. Europe/Berlin before, you do not need to change anything and in fact, you shouldn't see a difference. However, if you face time shifts between org and the caldav calendar you might try UTC.

Re: [O] org-caldav feedback
Hi David, time is correct now using UTC thanks a lot. My test suite runs fine with the SOGo server, so I'm guessing it has to do with how you format your entries. Does this also happen when you put the timestamp underneath the heading? Tested and you are right. Adding a timestamp in the body doesn't get lost during sync. Actually, I guess the problem is a combination of export and import to org-mode. During the export, the timestamp gets read in correctly, however, it get stripped from the Summary line (which is good). During the import, org-caldav does not find a timestamp in the body to update and does nothing (wild speculation). A possible solution would be to teach org-caldav to update the timestamp within the node header if available. I see the problem that you might changed the text in the summary field in the caldav calendar, which potentially mess up the header (where to place the old timestamp within the context of the new text?!) but for now, I would suggest to simply search for a timestamp within the node-header and update it by adding a new timestamp at the very end (but before tags ;) ). In addition a new variable org-caldav-timestamp-pos which can be either header or body could indicate where to place the timestamp for a new entry coming from caldav. Thanks again for this great work and I really appreciate your help and effort Torsten On a general note, I find manipulating Org entries rather delicate and wonder why there are no helper functions to change things like headings, timestamps, etc., which take care of the multitude of possibilities how entries can be formatted. My guess is that org-elements might be the solution for this, but I haven't looked at it yet... -David
Re: [O] org-caldav feedback
Hi David, great thanks a lot this solved the time shift problem. I did not had time to play with the different parameters. For now I simply added all of them. I guess it has to do either with the timezone or with the daylight settings. Maybe you want to add this to a How-to install for SOGo as a workaround. One problem remain. If I change something in the caldav calendar, the time information in org get lost completely. E.g. * Meeting 2013-01-16 Wed 14:00 becomes * Meeting It subsitutes the right entry and hence I believe it gets the ID stuff right. However, it seems to have trouble to interpret the time information right (and ignore them?). If there is a way to help you debugging this please let me know.

Re: [O] org-caldav feedback
Hi David, hehehe well we just started testing it a bit. Don't frighten there are problems... ;) So far, we could see appointments in the SOGo calendar which magically appeared after calling sync. Just to get started with problems: I noticed that there seems to be a problem with syncing events back to org. E.g., if I move a entry from within org-caldav, after sync I get a message about sync caldav-org, they still appear at the same position in the org-mode fie but the entry has no date at all. The old entry can be found in org-caldav-backup.org Furthermore, I notice, that entries have a 1 hour shift (an appointment at 9:00 in org appears as 10:00 in SOGo). I set already the timezone but the problem remain. Since 1 hour is exactly the time difference between UTC and the local timezone (Europe/Berlin), as well as summer/winter time settings, I would assume the problem is related to this. I know that this kind of stuff can be a mess. I would like to say that I really love the debug and sync messages. For those kind of procedures, I always frighten that something goes wrong unnoticed and I was really happy to see a the user readable status messages. I also noticed the files org-caldav-2094e16.el and org-caldav-backup.org. However, they are stored in my .emacs.d folder. Would it make sens to have an option to save them relatively to the org-file? E.g. relative to the path set in org-caldav-files? That would help to keep infos together and might be even a security concern (e.g., you might forget to move or delete backup infos in .emacs.d)!? Thanks, that's good news. I'm actually pretty surprised that it works right out of the box. Any plans to sync tasks too? SOGo calendars allow to set events and tasks (not sure whether tasks are part of the caldav specs). From what I can say they differ only in the fact that a task has a certain deadline and can be marked done. Thus, this would be equivalent to a TODO DEADLINE entry in org-mode Thanks again for this great work and please tell us how to help you to get SOGo 100% compatible, we would like to help as much as we can.

[O] Export a weekly calendar view from org-agenda

For the good old offline times, I would like to carry a printed version of e.g., the last week, current week and the next week with me (e.g. printed all on a double sided printed A5 page). That would allow me to jot down changes and have a quick look on my schedules at all time. Those changes, I would transfer back as soon as I sit again in front of a PC. I notice that I tend to forget to enter appointments just out of my head esp. if things get busy. The second benefit would be that I can file those weekly paper copies, in a classic manner and hence keep a paper based backup version (which due to the overlap even has a CVS like versioning mechanism ;)) just in case. I started to use org-caldav and hence, I know about the possibility to perform an export to caldav and using a calendar program with caldav support to print such a calendar. However, the groupware I am using does not allow pretty printing of the web-based client and I hesitate to install another client (most are big beasts like thunderbird+lightning, evolution, etc.) just for printing. In addition I would like to keep the workflow more org-mode centric and not caldav centric. Hence, a direct export from org-mode would be more welcome. I somehow remember that there was a way to create a PDF file but I can't find it anymore and I remember that the entries overlapped each other and it wasn't that pretty.

Hi, there exist a contrib http://orgmode.org/worg/org-contrib/org-git-link.html which allows you to link to specific versions of a file under git control. Thus, you can describe a error/feature/behavior in a file and make sure the description remains valid even if you change the file in the mean time. E.g. you can document your bug fixing with ¨before¨ and ¨after¨ links. I believe that this is a very important feature if you work with git and org Greetings Torsten On 3 January 2013 14:48, Jambunathan K kjambunat...@gmail.com wrote: Luca Ferrari fluca1...@infinito.it writes: Hi all, I'm using Org mode to manage my coding projects, that are all based on git.

[O] How to get a paper scanner into org-mode workflow
Hi, I plan to buy a document scanner with ADF and duplex function to scan all incoming/intermediate/outgoing papers, convert them into PDF and link those into my org-files. I was wondering if someone did something like this already? I use Linux and hence I am looking for a Linux friendly solution. On the web I found scanbuttond which enables to run a script if a scanner button is pressed and it seems scanning under Linux is rather scriptable. I want to make this finally as smooth, easy and painless as possible to make sure I do not pile up papers because I am to lazy to scan them on a day by day basis. Ideally, I want to fill the ADF unit, press a button, receive a single PDF with all pages scanned duplex in a preset folder, and keep a path to that file in org-modes killring to place it as a link at the right place. OCR would be nice too to get a full searchable system. I guess I am not the first one who tries this and I would be glad if people share there experience and set-ups. Thanks and happy new Year Torsten CC. Any recommendation on a well working scanner under Linux. At the moment my favorite is the Fujitsu ScanSnap S1500. Seems to work out of the box and comes with a good performance.

When getting Org from ELPA (either org or org-plus-contrib), org-loaddefs.el will also be in the load-path. When getting Org from git, you *HAVE* to created org-loaddefs.el with `make autoloads' (which is also run by a simple `make'), otherwise some needed functions will not be autoloaded.

Re: [O] Problem: Moving rows in a table changes vsum start and end
Hi Carsten, Thorsten, if you look at the manual, there are ways to write this limits of vsum etc in a way that they are relative to the table boundaries or to horizontal lines. This is robust agains changes of rows. Yes I know, thanks for pointing to it. It is just an dangerous culprit since people might not be aware of the fact that the formular changes along with row-moving operations. Esp. if you use vsum or other range based operations (with a start and end), one might expect that there should be no change. I can only speak for myself, however, as great as it is to use org-tables, I always have this little paranoid fear that certain cells did not get updated correctly, might it be due to wrong inputs from my side or because of a hidden bug. For really critical parts, esp. during the set-up of a new table, I find myself checking the numbers by hand again to make sure its going to be ok. Another problem I faced sometimes is the fact that after a while I forgot that a certain cell is addressed by a formular. I do changes by hand and just the next press of C-u C-c C-c might overwrite them accidentally without my notice. Having overlays or any sort of highlighting might be very helpful (and as the nature of emacs, people might just decide to turn them on and off if they get annoyed). I was thinking of: + Mark all cells/numbers which depend or are part of a formular (kind what we have already in the formular editor but for all and every forms) + Mark all cells which were updated by C-u C-c C-c (as the above but in addition being now different compared to the previous result) + Mark the parts of the formulars which using the cell in which the pointer is currently placed (reverse compared to the already existing formular highlighting) + Mark all cells which have by formulars some relation to the cell in which the pointer is currently placed (use two colors to indicate inputs and outputs) Those would give me a much more confidence, e.g., that all the fields are updated correctly, that I did not overwrite by accident an calculated value and it would help me to understand quickly the relation of cells even months after writing down the formulars.

[O] Problem: Moving rows in a table changes vsum start and end
Hi, I just notice a funny row-shift effect, having a table with a field calculated by vsum. | Nr. | value | |-+---| | 1 | 5 | | 2 | 5 | | 3 | 5 | | 4 | 5 | | 5 | 5 | | 6 | 5 | |-+---| | Sum |30 | #+TBLFM: @8$2=vsum(@2..@7) now shift (sort) the rows by using M-arrowup and M-arrowdown | Nr. | value | |-+---| | 1 | 5 | | 6 | 5 | | 5 | 5 | | 3 | 5 | | 4 | 5 | | 2 | 5 | |-+---| | Sum |10 | #+TBLFM: @8$2=vsum(@2..@3) Check, the #+TBLM:-line changed too! This might be desired sometimes but might also trouble people if they do not give careful attention. I know someone could do | Nr. | value | |-+---| | 1 | 5 | | 6 | 5 | | 5 | 5 | | 3 | 5 | | 4 | 5 | | 2 | 5 | |-+---| | Sum |30 | #+TBLFM: @8$2=vsum(@I..@II) But still I feel that people can too easily trap into wrong calculus. One solution, I could see is then whenever forms change automagically highlight this changes within the TBFM line, e.g., by a change of the background color in a similar way like matching parenthesis. That might help to make people more aware of it and shows which equations are affected by the current operation. All the best Torsten

Re: [O] Problem: Moving rows in a table changes vsum start and end
Hi Bastien, ok, I think it should be in org-table.el and the function in question might be org-table-fix-formulas I added (defface org-table-formular-change-face '((t (:background red))) Used parts of tabe formulars which change by row and column moving operations.) to define a new face for changes in the formular. Then I looked around how to do the face changing. By that I noticed, org-mode uses its own set of functions (org-table-highlight-rectangle, org-table-remove-rectangle-highlight). Searching more around I figured out that emacs already comes with a function for highlighting. http://www.gnu.org/software/emacs/manual/html_node/emacs/Highlight-Interactively.html#Highlight-Interactively Which makes me wonder why org-mode don't use that (maybe historical reasons, the above function is not that old). From this there are mainly two functions of interest highlight-regexp unhighlight-regexp (btw. a not very emacs conform naming) they take a regular expression as input and optional the face to be set. It works great in interactive mode. So I was looking how to modify the function org-table-fix-formulas using the above commands I ended up with a very small change (defun org-table-fix-formulas (key replace optional limit delta remove) Modify the equations after the table structure has been edited. KEY is \@\ or \$\. REPLACE is an alist of numbers to replace. For all numbers larger than LIMIT, shift them by DELTA. (save-excursion (goto-char (org-table-end)) (when (let ((case-fold-search t)) (looking-at [ \t]*#\\+tblfm:)) (let ((re (concat key \\([0-9]+\\))) (re2 (when remove (if (or (equal key $) (equal key $LR)) (format \\(@[0-9]+\\)?%s%d=.*?\\(::\\|$\\) (regexp-quote key) remove) (format @%d\\$[0-9]+=.*?\\(::\\|$\\) remove s n a) (when remove (while (re-search-forward re2 (point-at-eol) t) (unless (save-match-data (org-in-regexp remote([^)]+?))) (if (equal (char-before (match-beginning 0)) ?.) (error Change makes TBLFM term %s invalid. Use undo to recover. (match-string 0)) (replace-match ) (while (re-search-forward re (point-at-eol) t) (unless (save-match-data (org-in-regexp remote([^)]+?))) (setq s (match-string 1) n (string-to-number s)) (cond ((setq a (assoc s replace)) (replace-match (concat key (cdr a)) t t)) ((and limit ( n limit)) (replace-match (concat key (int-to-string (+ n delta))) t t))) ;Added the single line below (highlight-regexp re 'org-table-formular-change-face) ; really only the above line )) However, it does not work. Defining the face and using the above line works correct in the scratch buffer, However, calling the function within org-mode (moving rows in a table) I do not get an error message and do not get a highlight... I made sure my modified version but no luck yet. I greatly lack elisp knowledge, would be glad if you could give me some advice why it doesn't work. Furthermore, you might like to check about the highlight functions. You might be able to simplify some of the org-table.el code by relying on those functions instead of defining own functions. If we get this started, I dream of slightly different face different parts of org-tables: * cells base on a formula and not been updated, despite changes were made in the table, * cells base on a formula but good overwritten by the user (this is another dangerous situation I found myself in) * highlight the formulas for the cell in which the pointer is located (kind of reveres of the current fomular editor highlighting) * highlight changes after recalculation of an table As for the last point. I also found the minor mode highlight-changes-mode This is a great mode and calling it before starting to manipulate a org-table, already ticks some of the above points. Please try if you are not aware of it (create a table with some forms, call highlight-changes-mode, do some operations on the table).

Re: [O] Using org-mode for laboratory notes.
Hey, this is a nice idea and makes me wonder if it would be possible to use templates to automatically commit all recent changes in a git repro, and start a new day by a new fresh working space in git. git links are already possible. The template could create a link to the just checked in status in a extra org-file. You would end-up with a link for each date and file that changed and following this links, your files would magically be set-back to that particular timestamp. Furthermore, having the capabilities to see the diff and to see the history of not only complete files but of single headlines in org-mode would be then very helpful. I believe having a more tied integration of git capabilities within org-mode could really come up with some nice solutions.

Its nice and some of the ideas could be shamelessly stolen for org/org-babel. E.g. the mouse-support is great and would fit well to org if we think of emacs on tablets. However, I think it is in a very very early stage and one would need to see how it develops. I do not like the ruby-bridge. This looks to me very fragile and I had bad experience with python. Those bridges tend to break whenever there is a change on one of the sides ext. language or emacs. It also changed the entire appearance resp. face of my emacs session not sure why it did this. Feels a bit invasive and alienating. Nevertheless, its good that this kind of things get tested out and maybe in a future release of Emacs, we can see some of the ideas in the Emacs core.

Re: [O] Using org-mode for laboratory notes.
Hi, one way which works rather differently is the combination of git and org-mode. You could write your protocols in separate org-files and link to them in your records. org allows (at least it did a while ago) to link not only to a file but also to a specific version of a file. You could do small modification in the protocol-files as you need them and check them into the git system. Link to them and you will see the version you used for exactly this experiments. Actually using something like git and a git sensitive link is important if you might plan link to a lot of external files. Imaging you overwrite a file by accident or because you can't remember you referred to the original file already. A normal link would quietly point to the new file and would not be in-sync with anything you mentioned in your org-file. Other benefits are gits diff, merge and change-recording capabilities. If you set-up the git repro with entire lab-book on a server (a PC reachable from all your other devices) you could easily add data from within the lab, go to your office to add more data and at a certain point merge all this together. Both PCs could work offline and only need to be online for check-in and check-out new data. Another benefit of combining org-mode and git... you can tag certain versions of your lab book. E.g. tag them whenever you write a paper and make a notice in org-mode. This enables you to get back to all the measurement and reps. data evaluation results as you found them during writing your paper, even years and many many changes later (e.g. you might improved your data analysis method over time but for the paper you still want to see the old stupid way how you dealt with the data). Recently we got an org-file sensitive git-module, which makes merging org-files much more nice. Check here: http://orgmode.org/worg/org-contrib/org-git-link.html http://orgmode.org/worg/org-contrib/gsoc2012/student-projects/git-merge-tool/index.html Albeit I have to say I like to do all kind of stuff in org-mode, I faced problems using only org-mode as lab-notebook. Sometimes things in a lab are to numerous and to verbose to type them all in as they happen. Sometimes a little sketch, some quick scribbled note, etc. contains the real important data sentences like Damn, Joe slammed the door AGAIN, during an AFM measurement. Or in your case Uhh.. what are the funny little flakes in my buffer solutions I think sometimes a keyboard still filters to much and hence org-mode might not really contain all the necessary info. As a summary: org-mode as a lab-book will work fine if you are strict in using it and force yourself to be verbose enough. Hope thats helps Totti CC. There might be some legal issue with real lab books and electronic once. Back in the good old time where scientists didn't publish each and every result and where it could take many many months until some discovery reached the other side of the planet, the laboratory books where the legal evidence of the original work. If someone made a wrong claim or someone accused someone else of falsify reporting, the laboratory books where used to proof those claims. That is the reason, you find e.g. nicely archived laboratory books of all the great scientists of the Bell laboratories. Not sure how much this is still relevant today.

Hi Jonathan, does that mean we can mark the point * TODO org-mode should read my mind from the requested org-mode feature list ;) I think your example is great but frighten to be very specific to really get attention. However, it might make a nice example for presentations etc. Similar like the emacs coffee maker stuff. On the other hand it might be very interesting to get a general idea how to add data from devices to org-mode. Many measurement devices utilize USB, RS232 or even network interfaces to communicate (beside of the industrial standards). It would be great to have infos how e.g. to read data from a serial port and add them to org-mode. The internet-famous Arduino board could serve as an example. Communication would be even more awesome. Once I tried to use org-babel talking to a device connected via USB (emulated serial port). The protocol was rather simple but could be lengthy to type in over and over again. I was hopping to define babel blocks which serve as macro containers and combine them into bigger scripts. However, this did not work as well, I guess partially because of the bridge of org-shell-terminal-command If you could help to describe e.g. a raw communication port for babel that might be interesting. #+begin_src: raw :port /dev/tty1 :serpar 115200,8,1,N :results output command command command command #+end_src #+result response response response response With the right set of parameters one could fetch real world data directly into org-mode files.

Re: [O] Please consider making a donation
Hi Unfortunately, org-mode is too complete already. Otherwise we could have a bounty fund race on Worg... list the top ten requested features and ask a price for it according of what you believe it would cost you to implement it. People who donates can donate to one or the other feature request. If the price is reached, work can start. If the limit is not reached in a certain time the money might be spend to other feature request in a equal manner. Some sort of org-mode own kickstart projects. Just guess that people like to donate more easily if they have a certain target in view. However, org-mode might be to complete and to uniform to allow a clear separation of different feature requests.

As an aside, Thinkpads are pretty notorious for living through hell.

Re: [O] Latest version of Org-mode 7.8.3?
Hey Ciaran, as far as I remember you need to call (require 'org-install) to make emacs load your installation instead of the default one. Add it to your emacs config and check out org-version again Also you might be interesting to use the emacs-package manager which is a rather new feature of emacs. Org-mode versions there might be a good compromise between stability and up-to-dateness.

[O] [babel] ob-java error org-babel-execute-src-block: Wrong type argument: characterp, -cp .
Hi all,
every year I want like to evaluate java snippets in org-mode to
evaluate courseworks.
This worked fine but recently I had a bigger data crash and re-setup
my office machine.
It worked ok for the crash (that is it worked ok for the set-up at that time).
I use now
GNU Emacs 24.1.1
Org-mode version 7.8.11
I can evaluate simpler blocks but for more complex once I run into trouble

Re: [O] are super-hidden technical blocks required?
Hey Bastien, On 7 August 2012 19:23, Bastien b...@gnu.org wrote: that a drawer doesn't make an entry non-empty while cycling, ohhh you challenge us... does not ... non-empty is in fact the same like if there is only a drawer, the entry is still empty right ?! Yes, I agree that should be separated. Maybe an idea would be a rule like if all properties in a drawer are marked as hidden and there is nothing else for the particular entry (no body), do not open the entry for the next cycling rounds. I just tested a bit and org-mode is clever enough already to avoid any text-insertion before the property drawer if text get added to a collapsed entry. Thus, this rule just might work and hide technical properties completely during cycling. Combined with a #+HIDDEN_PROP: line each and everyone can adjust individually how much and what he likes to hide. #+HIDDEN_PROP: * - all properties are hidden would be the extreme and all property drawers will be hidden in case they are the only element of a entry. In case other elements are included, they collapsed drawer line will be dimmed by a different face to indicate that only hidden properties are included #+HIDDEN_PROP: this means no properties are hidden would be the other extreme and nothing would be hidden (that essentially would represent the present state). I created two mock-ups. One shows the present solution and the other shows how certain properties can be marked hidden and which effect does this have on different level and combinations. Hope that helps within this discussion. I choose a arbitrary colour scheme to make it rather good visible.

Re: [O] are super-hidden technical blocks required?
Hey Christopher,
* All entries are unfolded one level
** Only hidden properties with other content
This is more content
The :PROPERTIES: is not shown.
I left it there, because some people claimed the dislike to hide
property drawers to much. A different face colour might be a good
compromise.
Question -- are you proposing a new step in cycling that opens all property
drawers, or is this already available via some command or setting? I've
never seen a way to open everything including PROPERTIES via Tab or S-Tab
cycling.
No, I do not know how to open drawers by tab-cycling and would not
propose it. This view is just to show the most verbose way by open
each property drawer in addition manually.
The nice part on this solution, change the properties in the
HIDDEN_PROP line and you can get a complete different view only focus
on what is important for a certain task. It would rather easy to adapt
it quickly to the different requirements. I believe this goes even
further rather then only hide technical properties. E.g. entries
with many properties could be limited to show only what you are
working on.
See for example the following entry which I stole from Thomas S. Dyes
post about org-bibtex.el

This has many properties. If you have hundred of this entries you
might be interested to see only AUTHOR and YEAR line for some task. I
am aware of the column view but with the proposed method people could
get a plain text view only showing what they just need. If the
HIDDEN_PROP line could include regular expressions one could even
negate a list to get a hide all but behavior. To get

Re: [O] [babel] ob-java error org-babel-execute-src-block: Wrong type argument: characterp, -cp .
Hi Eric, AAGGG now I remember I participated in that discussion to replace #+BABEL by #+PROPERTY. that is the pitfall if you reuse stuff only once a year and heavy development goes on in the mean time ;) Thanks for the reminder and yeah now all works out ok. Just as a note to myself and maybe others who read this... #+PROPERTY: :mkdirp t #+PROPERTY: :cmpflag -cp . #+PROPERTY: :cmdline -cp . This is what is needed to set the flags for the java environment #+BEGIN_SRC text :tangle ./item1.txt A B C #+END_SRC This blocks allow you to TANGLE files which you might need to test your code (simulate input etc.) The problem here... you need to TANGLE them... NOT execute them. So now it works again. The problem was a PEBKAC... Thanks Eric Torsten
Re: [O] are super-hidden technical blocks required?
Hi, I would say this discussion is just showing how difficult it becomes to save all extra information provided by more and more 3rd party tools in a smart way in plain-text. I can understand both arguments * hide stuff which is not useful or needed for the user vs. * its my data and my file, I want to know what is stored in it. The extra property line is really verbose if the only element inside is a ID, a timestamp, or some other technical stuff. Imagine a single list of task each only a view words on a single line. The property drawer adds three lines to this just to add an ID. Even collapsed it still doubles the amount of lines. However, hiding even the collapsed property line has the danger that people might forget about it and that devs need to make sure that by any possible way of copy and pasting (and emacs knows many ways) those hidden lines are not left behind, that text get not added in between and the syntax remain valid for all kind of operation. I am unsure how to deal with this. Any kind of font face, special character, etc. on the next line below the title does not really give any win. There will be still a second line per tree-node. Adding something to the title line itself is tricky too. The title line is rather full already with all the possible features. I still prefer the proposed selective masking of properties to hide them. In addition maybe a flag can be set to + hide a property drawer line, + set a different font face, + or leave it as it is for the special case that the property drawer only contains hidden properties. But I frighten that this, even it might be the most flexible solution, might also be the most complex one to implement. So how to satisfy both views, a clutter free view and the awareness of what is saved in your file? Torsten
Re: [O] are super-hidden technical blocks required?
Hey, during this discussions people already claimed that they would prefer to know what is stored and I can understand this. That was the reason for the proposal of a HIDDEN_PROP: line to mark certain properties hidden. The benefit of this approach, people are actively aware of what they hide and they can hide whatever they want, even stuff which they might under other working schemes. E.g., for a certain workflow they might prefer to hide each and all properties. I can see the point that the property drawer header can be annoying too. Actually, when I used orgmobile for the first time I was not too happy to see all this property drawers suddenly appearing in my files. Even proposing it first, I would not suggest to introduce a second kind of drawer anymore. Chances are great that people start mixing informations between two different drawers and then stuff could get ugly and messy. It also introduce much new syntax and bug-fixing, problem-solving, and further improvements have to be done for two almost identically cases. Alternatively to a new kind of drawer, I would think of the HIDDEN_PROP: line and an additional method which hides a drawer even more if it only contains hidden property elements. That could be done, for example, by the already mentioned custom face. That is, a drawer is clearly visible if it contains properties intend to be read/changed by the user (not marked invisible). A drawer is less visible, if it contains only properties marked as hidden. Hidden properties do not reveal by the normal way of opening a drawer. However, there presence might be indicate by a ... line at the end. A special key-combo reveals them (e.g. for debugging, or as some kind of expert-mode). That would really give the largest amount of flexibility, is backward compatible, does not introduce to much new syntax (just a new header parameter) and people can easily change what should be visible and invisible by changing one single line. BTW. Timestamps of the last changes are really a good example for a hidden property. I was thinking already of a hashtag created by the title and body of a node. That could be compared by synctools with the present hash and thus, local changes could be identified. If I just would now more about elisp ;) Greetings Torsten
[O] [OT] Generate animations (programmatic)
Hi, its a bit OT (well maybe there is a babel solution ;) ) I am looking for a way to generate small animations for educational purpose. I know many here did/do/plan to do similar things, thus I would like to ask here. Those animations need to follow some underlying algorithms (I would need a correct physical, chemical, biological behavior). I'm not an art person (so please don't tell me to get pen and paper) and do not have the time (well the animations should help me but they are not my daytime job) to spend hours or even weeks in getting Blender and Co creating (superb) animations. Thus I am looking for: * Possibly a programmatic way to create animations * Something with a good balance of effort vs. output * Possibility to either inject results from other programs (scilab, python, matlab, etc.) or to include the necessary behavioral model * The output should be readable on many different platforms (Linux, Mac, Windows, Android, IOS, etc) * An open and well described output format * An open and well described workflow Well, the last two points are important to me, since I might use the animations for longer time (course material) and I would like to have a chance to open and modify them even in 3, 5 or even 10 years. My ideas so far * Processing language (seems interesting and fast to get results, however, not really an open output format, can't see the future of it clearly) * ProcessingJS (this solves the problem of having a easy to read output format, other problems are still the same) * Adobe flash (violates several of the above requirements, plugins on different platforms are a mess) * SVG + HTML5 (this looks promising as many web-browser would be capable to open it without plugin, but I can't find a programmatic easy way to start with this, any authoring tools, libs or APIs?) * TIKz + animation (I use Tikz already and really like it. Never used the animation package. However, animated PDFs are only readable with the Adobe Reader) * Python (well Python as a general language might work nice, however, which package could be used for animation? I used once pygames but this seems to be graphically disadvantaged) * Inkscape (there are modules to do animation, but how to get my behavior model into it?) * Blender, Gimp (steep learning curve, many many ours of work to get an animation) * Synfig, Pencil, ktoon, etc (maybe faster results compared to Blender, but again, how to get my behavior model into it?) * Powerpoint, Libreoffice Presenter (well, as soon as it comes to a bit more complex animations this becomes fast a nightmare) Ideally, I would love to see something like TikZ with a good way to add animations and to finally generate a SVG-based animation readable by almost all webbrowsers. This embedded in a language which allows me to perform the behavioral modeling too and I would be quite happy already. I would be glad if some of you could share there ways, ideas and workflows to do this kind of animations. All the best Torsten
[O] [odt] Export of LaTeX Fragments
Hi,
today I had to send over a document in MS Word format. Suprise suprise
guess I am not the first one on that mailing list.
I was happy to use the new odt export feature and it did the best job
out of some other constellations (org-html-word, org-pdf-odt via
pdf import plugin, org-pdf-copy paste, etc.)
Thanks for this brilliant feature!
I have a minor problem, I used some LaTeX format commands. I know I
might get away by replacing \textbf with *text*, etc. But know its
there already. Sure it worked out great for the LaTeX-PDF export.
However, in openoffice I had stuff like \textbf{text}. I was
wondering, the exporter is doing all this nifty work already, could we
have a flag to replace the most common Linux inline text-formats by
the corresponding odt format?
\textbf
\textit
\underline
\mbox (no line break)
\, (protected blank)
would be a good start
Thanks
Torsten
