[O] Emulate a wiki a la wikidpad
Hey guys, I love orgmode and I've been using it for many years. I know there are wiki extensions for it and other extensions for emacs, but I've never found something as easy and straightforwards as WikiDPad. Wikidpad is a real-time wiki. It's really cool (http://wikidpad.sourceforge.net/). What I'm looking for is an extension that could automatically link camecased words in org files, and create its respective file in a specific directory, if the file does not exist. I know it wouldn't be too difficult to implement, but I'd like to check here first before trying to come up with a solution myself. The rationale is that it's a really great way to keep reference data, and since it's in real time, you don't need to export to a format like HTML to view it. It's just so convenient when brainstorming or for keeping notes. Cheers! Marcelo.

Re: [O] Drag images from Firefox to org-mode
Hi Carsten, The dependencies are async, dnd and wget. In case dnd doesn't work, there's a fallback to clipboard via `current-kill'. I've just added a custom variable that takes either 'wget or 'curl as the download method. I tried before url-retrieve, but it was giving me some garbage in addition to the image. So unless I know reliably the format of the garbage I can't use url-retrieve. But if I figure it out, I could add url-retrieve as the third custom method.

[O] linebreak after tag of headline in ox-latex.el
Hello,
I export frequently minutes with todos with latex to pdf. I always
include planning information, e.g.:
* NEXT Check this :Rasmus:
DEADLINE: 2013-10-15 tis SCHEDULED: 2013-10-15 tis
+ some comments
After upgrading to (Org-mode version 8.2.1, GNU Emacs 23.4.1 ) the
deadline and schedule is not linebreaked after the tag. This gives a
unwanted output with all task information on the same line.
Without knowing if it is the most appropriate solution I propose adding
\n in the last row of:
(defun org-latex-format-headline-default-function
(todo todo-type priority text tags)
Default format function for a headline.
See `org-latex-format-headline-function' for details.
(concat
(and todo (format {\\bfseries\\sffamily %s} todo))
(and priority (format \\framebox{\\#%c} priority))
text
(and tags
(format \\hfill{}\\textsc{%s}\n (mapconcat 'identity tags :)
, in order to get a better output of the task todo. I tried the above
and compiled and got the output as I wanted. However, I don’t know if
there are any inconvenience by doing so.

[O] Export org to dot for an organization chart?
Hi, I'd like to produce an organization chart using org. What I want to do is: - enter an organization role as a section heading - have the heading hierarchy map to the organization hierarchy - enter optional section properties to specify: - the name of the individual who might fill the role - color and line types for drawing the box for the role - a URL associated with the role - section text providing a brief description of the role - render this into some nice looking graphic The end result I'm going for is a clickable image on a web page made by rendering the organization chart such that clicking on a box sends the browser to the role-specific URL and the alt text for that link gives the section text. Is there already something along these lines? Some searches turned up empty My thinking is that if there was an org-export-as-dot then it would be close to what I want. I found org-export-as-freemind which is in the right direction but I think lacks some of what I want and I'd like to avoid using a GUI in the process. Thanks for any ideas on this. If there is nothing like this yet, maybe I can use it as an excuse to learn org's new export system. -Brett. PS: rough example org file might look like: * Boss :PROPERTIES: :Actor: Bob Bigbooty :URL: http://www.example.com/boss.html :NodeColor: blue :END: The boss dictates. ** Middle Manager :PROPERTIES: :Actor: :URL: http://www.example.com/layer.html :NodeColor: red :END: The middle manager spectates. *** Flunky :PROPERTIES: :Actor: Sam Small :URL: http://www.example.com/hardworker.html :END: While the flunky gets stuff done. pgpd7J_RKfACP.pgp Description: PGP signature
Re: [O] Drag images from Firefox to org-mode
Thanks, Rick and Nico, I've merged the code. All except the last bit from Rick: I can't think of any sensible way to enter an image URL except pasting it. And since link will be in the clipboard at some point, why not use it straight away without prompting. Maybe URL can be prompted for when called with a prefix arg, but I don't know how to do that yet. regards, Oleh On Fri, Oct 18, 2013 at 8:24 PM, Rick Frankel r...@rickster.com wrote: On 2013-10-18 11:36, Nicolas Richard wrote: Note that using (let ((coding-system-for-write 'no-conversion)) (write-region nil nil filename nil nil nil 'confirm)) instead of (write-file ...) seemed to fix the problem for Oleh.

And since link will be in the clipboard at some point, why not use it straight away without prompting. Maybe URL can be prompted for when called with a prefix arg, but I don't know how to do that yet. I strongly disagree, for a couple of reasons: - Esp. on non-unix systems, the contents of the cut-buffer are not necessarily the same as the contents of the system clipboard. This is the problem I was having w/ your code on windows, where the cut-buffer contained the value of the current (or possibly last) selection, but the clipboard had a url. - It is certainly possible to type in a url - You might want to DND a url from another buffer. - It is ergonomically wrong for an interactive function defined to take an argument (and called download-image) to automagically use a value from somewhere else and not actually take an argument. It would however, make sense for the function to use the current clipboard contents if called with a prefix. In the same vein, I was thinking about the automagically creating a subdirectory based on a top level heading. This is also wrong for a couple reasons: - Creating a potentially =very long directory name with spaces= can cause multiple problems, both on unix and esp. non-unix systems, where spaces may not be allowed in directory names, or there may be limits on filename/directory length. - The use of the top-level heading is arbitrary and may have nothing to do with the current context (for instance, i sometimes group together multiple documents to be output w/ export subtree in the same master document) The default should be to save it in the same directory as the document (which by the way, may not be in emacs's idea of the current directory). Also, the filename should not be expanded to an absolute path, which makes the document non-portable and will break publishing. If you want the ability to create arbitrary output directories based on document context, the customization can be made to accept a function (lambda) as a value, which could then return a directory prefix. While i realize the current implementation meets your needs, if the code is to be included in the org-mode distribution it should follow emacs and org conventions and not contains any suprises. I would be glad to make the above changes on tuesday when i get back to the office. Please send me (again) the url of the github repos with the current set of changes and I will update it so that it will allow the current functionality but have less magical default behavior. rick
[O] Create sub-directories and files from within org
If I create a project with ** project name, is there any way to create a sub-directory at *** level in ~/projects/project name and create txt files in that directory - all from within org? Thanks.
