Recently, stackexchange started a similar project:

You can create a context tag and create example documents. The difficulty 
with such projects, as usual, is to have a critical mass for others to 
browse and contribute. One could start by "porting" existing examples from 
the wiki, mailing list, tex.stackexchange, etc.


Scratch that. It seems that documentation tags can only be created for 
topics that are popular on stackoverflow (not stackexchange).

Hello Wolfgang,


Le 09. 10. 16 à 22:51, Wolfgang Schuster a écrit :
Many of the old manuals got updates by Hans and he included the PDF’s 
(together with the source files) in the normal ConTeXt download, you 
can find them in the doc folder in your ConTeXt installation.


Ok, I don't have enough the habit of consulting documentation that is 
installed in my system. I have found something interesting here that 
could be helpfull to me : 
/usr/share/texmf/doc/context/base/examplap/gui/letter.pdf. It seems to 
be a letter generator, but unfortunately I wasn't able to make it work. 
Maybe it is outdated since it is 10 years old.


The wiki has a page for examples and you’re free to update the 
existing examples or add new ones.


Do you mean http://wiki.contextgarden.net/Sample_documents ? Yes, that's 
a good idea, since I believe that it is a way to improve documentation 
with little efforts. Then I plan to add the cover letter style I made 
since I am happy with the results, although 1 or 2 things could have 
some improvement. There are also some letter styles there, then I will 
have a look on them too. I don't know if people are intimidated about 
writing contents in the wiki because it is the official wiki and feel 
that only programmers are supposed to update it, but it will be really 
helpfull if the users have more the habit of posting there the document 
styles they made.



Sounds interesting and the best thing you can do is to start with it.


Thanks for your encouragement ! Yes that looks like an interesting 
challenge for me, but it is not something I am wanting to do alone 
because of my lack of experience, at least I would need someone to coach 
me. Actually I don't have really experience with web developpment and I 
would at least need help for the technological choices. Having someone 
that tells me that if I use technology X, there are module Y and Z that 
will be a good fit is a good start.


Have a nice day,
Jonas

Re: [NTG-context] Ideas for improving documentation of ConTeXt

Hello Henri,

Le 09. 10. 16 à 21:31, Henri Menke a écrit :

please don't be disappointed but you are not the first person to suggest such a 
thing.  You may now ask, why doesn't such a thing exist then?  Well, the basic 
answer is, go ahead and implement it.
I won't go ahead and implement it if I am the only one who would think 
it is a good idea. That's why I asked for some feedback. It happens 
sometimes that I could have an idea that looks great in my eyes, but 
then seems a little less shiny after hearing some feedback. But since I 
wasn't the first person to suggest such a thing, It seems to me that my 
idea goes in the right direction, isn't it ? It doesn't mean that no 
improvement is needed, and it still need to be implemented.



Most probably no one else will volunteer to do it and especially the people 
from PRAGMA surely have better things to do. They merely develop and use 
ConTeXt (...)
Here I don't agree. People from PRAGMA are probably better at 
developping ConTeXt than starting in parallel a new project like that, 
but it doesn't mean that this idea is necessarly not worth considering. 
I wasn't either suggesting that they should be the people who start 
implementing the idea.

(...) and were so kind as to provide us a huge bunch of documentation already 
(http://pragma-ade.nl/document-1.htm).
Yes I just saw that you are right about the documentation, they have 
already made a huge work on that. I was maybe too quick about my 
conclusion, I am sorry if I did offend those who have already make all 
that work. I was actually doing a cover letter in ConTeXt and since I 
wasn't able to find uptodate informations about some of the commands I 
was a little frustrated. But yes the letter module is third party and I 
just saw in the wiki that it is said to be still in developpment, so 
interface changes are to be expected and not necessarly all documented. 
Since I am new to ConTeXt, my views on ConTeXt documentation got biased. 
But now I am pretty happy with the results I have with my document, so 
most of the troubles are behind, I guess :-).


On the other hand, some of the documentation still need to be updated. 
Since ConTeXt is quick to evolue, having uptodate documentation would be 
a huge task and I also understand that it may not be the most 
interesting part for developpers ;-). My proposition was about to 
mitigate that problem with making accessible examples with some advanced 
search to quickly find relevant results.


Maybe someday ConTeXt will be more mature and have a more stable 
interface, then it would be easier to have uptodate documentation. But 
it is only the analysis of someone who is only starting to know ConTeXt, 
so I won't assume to be totally correct.


Cheers,
Jonas

Re: [NTG-context] Unable to use Martin Vogels Symbols

[Jonas Baggett]

Hello Henning,

Thanks for the feed-back! I first thinked it could be a bug that only 
occurs when ConTeXt has to find the martin vogel symbol font for the 
first time and update its cache, which would explain why the bug doesn't 
occur with the live ConTeXt compiler since the font is already in the 
cache. Did you try to remove the cache in order to force ConTeXt to 
regenerate its cache and see if it can still find the font ?


Anyways, I have sent a bug report to the debian maintainers and we will see.

Best regards,
Jonas

Re: [NTG-context] Ideas for improving documentation of ConTeXt

[Wolfgang Schuster]

Jonas Baggett 
9. Oktober 2016 um 13:18
Hello everyone,

I am new to new to ConTeXt and I was thinking about how to improve 
documentation to help users and then make ConTeXt more appealing. 
Because, if there is one weak point in my eyes with ConTeXt, it is the 
lack of documentation, which is too bad because ConTeXt seems to be 
really great. And google search is also a little tricky, since context 
is a common name. On the other hand, most of the help I found was on 
the wiki, the mailing list, TeX Stack Exchange and some pdf 
documentations. Sometimes, I also faced the problem about the 
documentation being outdated and when I am trying to find the solution 
on the internet, I may have a hard time finding solutions that aren't 
outdated too. The worse is maybe when a command option isn't working 
anymore with not even a warning.
Many of the old manuals got updates by Hans and he included the PDF’s 
(together with the source files) in the normal ConTeXt download, you can 
find them in the doc folder in your ConTeXt installation.
The basic idea I have is a database of ConTeXt documents, where 
everyone can add his own documents. We have also to make it easy to 
find there insightful examples in ConTeXt that will help someone to 
achieve what he is trying to do. Then users, especially beginners, 
will less likely be stuck at one point and looking for hours for a 
solution and less help will be asked on the mailing list too.
The wiki has a page for examples and you’re free to update the existing 
examples or add new ones.

Here are the basic concepts about the database :
- When someone adds a document, he can specify the type of the 
document like e.g. report, letter, CV, book, etc. Subcategories could 
be a good idea too, e.g. letters can have a subcategory called cover 
letters. Some extra tags could also be useful, like e.g.: math, 
luatex, tables, positioning, etc when there is some use of the 
preceding, maybe not necessarily essential when the use is only basic.
- If some extra fonts or modules are needed to be installed in order 
to make the example fully work, this could also be specified.
- Search could be done by specifying one or more categories and tags. 
It will also be possible to search all the occurrences in the database 
of a command with optionally a command parameter.
- It will be like a wiki so that everyone could improve the existing 
examples.
- It can be also useful to allow comments, because it is possible that 
an example is close to what someone is trying to do, in which case he 
will look on the comments hoping that there was already someone who 
asked there the question and got answered.
- In order to mitigate the problem with deprecation stuffs after some 
language changes, we could have all the commands and their options 
listed somewhere in the database, then when a command or command 
parameter is getting deprecated, it will be possible to mark it as so 
and provide some hints on how to fix it. After that, all the examples 
that use the deprecated stuffs will get a warning and hints will be 
showed about how to fix them. And since that examples are editable by 
anyone, there won't be hopefully very much of outdated documents.


Here some are possible scenarios about searching in the database  :
- Someone is writing a letter and is trying to move one element (e.g. 
date, his address, receiver address) in another location without any 
success so far. Then he will go to this database, choose letter as 
category and positioning as extra tag and launch the search. Maybe he 
will get about 20 results, then chances are that some of the found 
examples will be doing something close enough to what he's trying to 
do, so that he could analyse the source and understand what he needs 
to do in his case.
- Someone is looking about how to set the background color of a framed 
box. Then he will search occurrences of the uses of the \framed 
command which have color in their arguments. Then by looking at the 
found examples, he will find out that the color is set with the 
backgroundcolor argument and that the background argument need to be 
set to "color" too.


What do you think about the idea ? I believe this could be a good 
complement to the existing ressources.

Sounds interesting and the best thing you can do is to start with it.

Wolfgang

Hello,
I do not succeed in having two sub-columns of the same width in the 
third column.
Your table has four columns but you set only the width for the first 
three, adding a width setting for the fourth column helps.


\startsetups[table:initialize]
  \setupTABLE[start][align={middle,lohi},offset=0.8ex,style=\smallbodyfont]
  \setupTABLE[column][1][width=0.10\textwidth]
  \setupTABLE[column][2][width=0.40\textwidth]
  \setupTABLE[column][3][width=0.25\textwidth]
  \setupTABLE[column][4][width=0.25\textwidth]
  \setupTABLE[1][1,2,3][frame=off]

When you use the ConTeXt suite you have all manuals already on your

An important part are the updated and added manuals, have a look at
http://www.pragma-ade.com/overview.htm

LuaTeX 1.0.0 is announced and distributed.

Minimals contain a new cowfont (with colorable backgrounds) and some (most? 
all?) of the manuals.

Oh, and the new interface files (texmf-context/tex/context/interface)!

I guess, I was following these gradually as they were happening but I was 
thinking maybe other material from the meeting could be shared.  That's why I 
mentioned the slides of the talks.

The bitbucket mirror has not been updated since September 24.  Is that normal 
or the result of some configuration mismatch?

I guess, I was following these gradually as they were happening but I was
thinking maybe other material from the meeting could be shared.  That's why
I mentioned the slides of the talks.

The bitbucket mirror has not been updated since September 24.  Is that
normal or the result of some configuration mismatch?

Hi all,

I’m trying to write some dimensions to a file, e.g.

\startluacode
io.savedata("settings.txt", context("\\textwidth"))

But that context() construct is nil.
There’s probably a simple solution... ;)


\starttext

\startluacode
io.savedata("settings.txt", number.topoints(tex.dimen.textwidth))
\stopluacode

\typefile{settings.txt}

 (Their issues with stopper have been resolved. In MKIV it is numberstopper.)

Here is an MWE demonstrating the problem. It compiles cleanly, but the 
separator remains the default period. With MKII, it generates a figure with a 
hyphen and not a period.
\setupcaptions[separator=-]
\setupcaptions[prefixconnector=-]

[NTG-context] Ideas for improving documentation of ConTeXt

[Jonas Baggett]

Hello everyone,

I am new to new to ConTeXt and I was thinking about how to improve 
documentation to help users and then make ConTeXt more appealing. 
Because, if there is one weak point in my eyes with ConTeXt, it is the 
lack of documentation, which is too bad because ConTeXt seems to be 
really great. And google search is also a little tricky, since context 
is a common name. On the other hand, most of the help I found was on the 
wiki, the mailing list, TeX Stack Exchange and some pdf documentations. 
Sometimes, I also faced the problem about the documentation being 
outdated and when I am trying to find the solution on the internet, I 
may have a hard time finding solutions that aren't outdated too. The 
worse is maybe when a command option isn't working anymore with not even 
a warning.


The basic idea I have is a database of ConTeXt documents, where everyone 
can add his own documents. We have also to make it easy to find there 
insightful examples in ConTeXt that will help someone to achieve what he 
is trying to do. Then users, especially beginners, will less likely be 
stuck at one point and looking for hours for a solution and less help 
will be asked on the mailing list too.


Here are the basic concepts about the database :
- When someone adds a document, he can specify the type of the document 
like e.g. report, letter, CV, book, etc. Subcategories could be a good 
idea too, e.g. letters can have a subcategory called cover letters. Some 
extra tags could also be useful, like e.g.: math, luatex, tables, 
positioning, etc when there is some use of the preceding, maybe not 
necessarily essential when the use is only basic.
- If some extra fonts or modules are needed to be installed in order to 
make the example fully work, this could also be specified.
- Search could be done by specifying one or more categories and tags. It 
will also be possible to search all the occurrences in the database of a 
command with optionally a command parameter.
- It will be like a wiki so that everyone could improve the existing 
examples.
- It can be also useful to allow comments, because it is possible that 
an example is close to what someone is trying to do, in which case he 
will look on the comments hoping that there was already someone who 
asked there the question and got answered.
- In order to mitigate the problem with deprecation stuffs after some 
language changes, we could have all the commands and their options 
listed somewhere in the database, then when a command or command 
parameter is getting deprecated, it will be possible to mark it as so 
and provide some hints on how to fix it. After that, all the examples 
that use the deprecated stuffs will get a warning and hints will be 
showed about how to fix them. And since that examples are editable by 
anyone, there won't be hopefully very much of outdated documents.


Here some are possible scenarios about searching in the database  :
- Someone is writing a letter and is trying to move one element (e.g. 
date, his address, receiver address) in another location without any 
success so far. Then he will go to this database, choose letter as 
category and positioning as extra tag and launch the search. Maybe he 
will get about 20 results, then chances are that some of the found 
examples will be doing something close enough to what he's trying to do, 
so that he could analyse the source and understand what he needs to do 
in his case.
- Someone is looking about how to set the background color of a framed 
box. Then he will search occurrences of the uses of the \framed command 
which have color in their arguments. Then by looking at the found 
examples, he will find out that the color is set with the 
backgroundcolor argument and that the background argument need to be set 
to "color" too.


What do you think about the idea ? I believe this could be a good 
complement to the existing ressources.


Have a nice sunday,
Jonas

Re: [NTG-context] Unable to use Martin Vogels Symbols

[Jonas Baggett]

Le 07.10.16 à 22:53, Jonas Baggett a écrit :


Hello,

I am using debian testing and I am trying to use Martin Vogels Symbols 
with no success so far. I have compiled a file containing the following :

\usesymbols[mvs]
\setupsymbolset [martinvogel 2]
\starttext

The preceding code works with http://live.contextgarden.net/, so I am 
not sure if it is a Debian bug or a ConTeXt bug. Maybe I should send a 
bug report to the Debian maintainers and they will forward it upstream 
if it is a ConTeXt bug.
