[NTG-context] button
\button is defined to jump to a given reference. However, I would like to place
a button that can execute a macro to be defined by myself.
Thus for example pushing the button \executebutton{text}{macro} will execute
that macro.
Is this available somewhere in ConTeXT? If not, can it be provided in a future
update?
yours sincerely

Did you try \button[Options]{Something}[YourJSFunction] ?
I don’t know it that’s limited to a few predefined functions.
see https://wiki.contextgarden.net/Widgets#JavaScript and
https://source.contextgarden.net/scrn-but.mkvi
Just to be sure: You understand that this works via JavaScript in the
viewer, only supported by Acrobat and PDF Studio?

Another option might be to use a marker such as
% DE_figure_here param1 param2 param3
in your ConTeXt source and then use 'awk' or another Unix text pre-processor to
scan through for these, run the appropriate DE calculation, plot the graph and
generate the appropriate \placefigure command to go in its place.
Bonus marks if it can automatically generate the caption based on the
parameters! But if not, the marker can always follow the \placefigure macro e.g.
\placefigure
{This is a DE showing something and something else}
% DE_figure_here param1 param2 param3
so the awk code only needs to insert the image file name.
Note I’ve deliberately omitted the braces from the bit to be substituted so
that you need to generate them in the awk. That way, if you forget to process,
you’ll get an error not a missing image.

That sounds needlessly convoluted to me.
I’d use Aditya’s filter module to call external programs, it also does
caching, i.e. if the parameters don’t change, it won’t waste processing
time.

I think Florent already has a situation that can be described as convoluted.
Whether this is more so only he can say.
I didn’t suggest the filter module to start with because it filters a buffer
through an external command which isn’t Florent’s use-case (which is just the
ability to call an external command). However I see, buried deeply in the docs,
under the heading "Special use case: \write18 with caching” there is the
ability to call a single command which would work.
Someone with better knowledge of the macro would need to explain how to adapt
the ’size’ key to Florent’s usage to enable the caching.

[NTG-context] Re: Margins using 2UP imposition schema
Angel,
I used a lot of impositioning in the past.
If you want to have small white space at the outer edge, then do not use
width=fit. Control the inner whitespace with backspace=… Then calculate the
width of the textarea you want and set this value in width=... There is no need
to use cutspace in your approach.

[NTG-context] Re: Calling C code from ConTeXt LMTX
Thanks again Bruce! I had not thought about the possibility of parsing
comments in the tex file from an external tool, but that sounds like a very
good option. I like the fact that it would allow the tex file to contain
all the information needed to keep track of what is represented without
having to duplicate the parameter values. And since my specific workflow is
indeed already convoluted it will not really add extra complexity.
Thanks also Henning for mentioning the filter module! I'll have a closer
look into how I could use it - and it will certainly come useful, either
for this project or a future one!
Best regards,
Florent

[NTG-context] syntax highlighting: pandoc uses Kate
Hi, since we recently discussed editor support and syntax highlighting: Pandoc can use definitions from Kate[1] for syntax highlighting in a code block via "--syntax-definition". There’s also ConTeXt support (MkIV/LMTX): https://kate-editor.org/syntax/data/syntax/context.xml Apparently, it can switch contexts to Lua, XML, MetaPost etc. But the list of commands is quite short. In case the author (Philipp A.) is listening: Is this intentional (“not necessary, highlight everything that starts with a backslash”)? Otherwise it probably would make sense to read in the interface files (i-*.xml). I can’t tell if it would make sense to support this syntax via a module (like scite and vim). What we have if probably enough for most of us.

Please remove everything from your examples which isn't necessary to
show the problem, in your example you can get rid of
- the page layout,
- the font settings,
- the title page and
- all settings from \setupdescription and \setuphead unrelated to the
space between number/title and the text.
The value you're looking for is \spaceamount which can be used with the
distance-key to set the width of a space as separator.
For descriptions you have to set the value of the width to fit and use
the distance key to set a fixed
value for the space between the title and following text, to ensure the
space doesn't increase set
also the shrink and stretch values to 0.
begin example
\definedescription
[description]
[alternative=serried,
width=fit,
distance=\spaceamount,
stretch=0,
shrink=0]
\starttext
\startdescription [title={I'm not a fan of the}]
default spacing
\stopdescription
\stoptext
end example
For itemize you can use the fit keyword but be aware once you have more
than 9 entries you get
a bigger space between the number and content because the environment
set the width of all
entries to width of the widest number.
begin example
\starttext
\startitemize[n,fit][distance=\spaceamount]
\startitem
I'm not a fan of the default spacing
\stopitem
\stopitemize
\stoptext
end example
For section titles you just have to change the distance value.
begin example
\setuphead
[section]
[distance=\spaceamount]
\starttext
\startsection[title={I'm not a fan of the}]
default spacing
\stopsection
\stoptext
end example
