Re: [NTG-context] New VSCode extenstion using ConTeXt Language server

[Ramkumar KB via ntg-context]

Denis,

Thanks for the feedback.

No, you are not missing anything. The ConTeXt command list comes from a
file that Hans & Hraban maintain - to create the PDF version of the ConTeXt
commands guide that is available with the distribution -
https://wiki.contextgarden.net/Documentation (we convert that file into a
Typescript object and then use it in the Language Server).

Yes, this is an obvious improvement point that you have highlighted - I
will work with Hans & Hraban to improve it.

Best,

Re: [NTG-context] New VSCode extenstion using ConTeXt Language server

[Ramkumar KB via ntg-context]

Floris,
Can you please try with VSCode first in Ubuntu and see if this works?

We have never tried with Codium (unfortunately) and therefore not sure how
the Extension sytem works in Codium.

Best.

[NTG-context] New VSCode extenstion using ConTeXt Language server

[Ramkumar KB via ntg-context]

Hello All,

I have published the new VSCode Extension for ConTeXt, that I presented
during the 2022 ConTeXt meeting -

https://wiki.contextgarden.net/VSCode

You can install it manually in the VSCode (using the "Install from VSIX..."
option).
Documentation (for now) -
https://meeting.contextgarden.net/2022/talks/ramkumar/ramkumar-talk.pdf

This supports ConTeXt markup and for any Lua code (within \startluacode &
\stopluacode) it re-directs to the Lua Language Server (from Sumneko -
https://github.com/sumneko/lua-language-server )

To Do -

   1. Make the source code open-source
   2. Add new features (like Hover & Tooltip)
   3. Work with Taco to add MetaPost Language Server (this could be
   challenging and interesting)

Do give this a try and give your feedback. Note that this does not contain
*all* the macros but covers the vast majority of the ConTeXt commands.

Thank you,

best regards
Ramkumar

Re: [NTG-context] x86-64-amd-linux binary?

[Ramkumar KB via ntg-context]

Hans,

Thank you. Just to clarify, in my current installation - context and mtxrun
are already symlinks to the luametatex.

So all I need to do is replace the luametatex binay (dl from the build
server - debian9 build)? I also notice the luatex binary - I just leave it
as is?

best regards,
Ramkumar

Fascinating exchange of thoughts. Thank you so much for sharing.

[NTG-context] Any initial thoughts on luau?

[Ramkumar KB via ntg-context]

Hello,

Yesterday, Roblox announced - Luau - https://luau-lang.org/why - mainly
adding linting and type-checking features.

Being compatible with Lua 5.1 is probably a bummer but nonetheless would be
interesting to hear about this from this community.

Thank you.

[NTG-context] Indentation inside \framed won't go away

[Ramkumar KB via ntg-context]

Hello,

I have this nagging issue of indentation (in the 1st line) showing up
inside \framed in spite of all the commands to skip indentation (see
attached PDF).

It appears that *\setupindenting[no]* is not playing any role here and some
other parameter is overriding  this.

Any tips would be appreciated.

Ramkumar

Re: [NTG-context] Reading ConTeXt metadata values into Lua

[Ramkumar KB via ntg-context]

Hans / Wolfgang,

Thank you for your quick feedback and the tips. Yes, this works for now.

In general, I will try to avoid going into such "deep-end" APIs (at least
for now, until such time I read all the manuals in depth!). IMHO, the
standard ConTeXt system is itself quite powerful for 98% of the Typesetting
usecases.

best regards,
Ramkumar

[NTG-context] Reading ConTeXt metadata values into Lua

[Ramkumar KB via ntg-context]

Hello All,

I was trying to read the value of '\totalnumberofpages' into lua to do
something with it. As an example, see below.

Now, as I understand it, my example would not work as TeX gets the first go
at this and therefore the variable 'pages' is the string
'\totalnumberofpages' and not the actual value itself. And Lua cannot
process this "calculation".

I tried to go thru the manual -  *cld-mkiv.pdf  *- in the distro but could
not catch on how to read a metadata value (not print). I am sure that I am
missing a small trick somewhere (or is it something more involved?).

\startluacode
function myFancyCalculations(pages)
  -- some fancy stuff but as an example
local myCal = tonumber(pages) + 1
return myCal
\stopluacode

\starttext

\blah

\ctxlua{context(myFancyCalculations("\\totalnumberofpages"))}

\stoptext

Thank you in advance for any tips.

best regards,
Ramkumar

Re: [NTG-context] Does the ConTeXt distro come with a PDFViewer?

[Ramkumar KB via ntg-context]

All,

Thanks for the tips. SumatraPDF worked well as it updates as the underlying
PDF is refreshed by ConTeXt - which makes the dev-preview cycle really
quick.

I will compile all the tips in this thread into the Wiki.

best regards,
Ramkumar

[NTG-context] Does the ConTeXt distro come with a PDFViewer?

[Ramkumar KB via ntg-context]

Hello Community,

If my memory serves me correctly, I might have noticed (in one of the
presentations during the recent ConTeXt meeting) that the distro comes with
a PDFViewer. Is that a correct assumption?

I am currently using a VSCode extension for PDFViewing but it does not work
very reliably.

Thank you very much,

best regards,
Ramkumar

Re: [NTG-context] Best way to apply a fill-pattern to a closed shape?

[Ramkumar KB via ntg-context]

Hans,

Thank you! Yes, it would be great to learn more about MetaFun - if you can
point me to the test suite, then I can document a few good tutorial level
examples in the Wiki (beginner & intermediate). MetaFun's turbo charged
capabilities are awesome!

One idea I am thinking (maybe for a student level project) would be MetaFun
library for Figma <https://www.figma.com/> (popular design tool).

best regards,
Ramkumar

Thank you for the snippets. These are super helpful (I am assuming commands
like `withpatternscale` are MetaFun extensions and Wow!).

I have added them to a new Wiki Page -
https://wiki.contextgarden.net/Fill_Patterns and linked it the main MetaFun
wiki page - https://wiki.contextgarden.net/MetaFun_-_MetaPost_in_ConTeXt

Thanks again!

Re: [NTG-context] Handling of negative values in the statistical-charts?

[Ramkumar KB via ntg-context]

Hi,

I have added an 'advanced' type for line & bar graphs to handle the use
case for -ve y-values / 4th quadrant graphs. It works similar to 'basic'
but works for -ve y-values (i.e. for the 4th quadrant).

PFA the amended lua file (zip file) and sample of line graph.

\def\edudataone{-10,35.55,-20.0,33,31,-25,-32}
\def\yearlabelstwo{2013,2014,2015,2016,
2017}

\linechart[basic][
ylength=5,
xscale=1.6, yscale=0.1,
left=0.5,
distance=1.2,
linecolor=limegreen, linewidth=1.5,
dotscolor=islamicgreen,
dotswidth=8, dotslabels=yes,
axesunits=yes,
xunit=Year,
yunit=Number of graduates
(thousands)][
data={\edudataone},
xlabels={\yearlabelstwo}]

\linechart[advanced][
ylength=5,
xscale=1.6, yscale=0.1,
left=0.5,
distance=1.2,
linecolor=limegreen, linewidth=1.5,
dotscolor=islamicgreen,
dotswidth=8, dotslabels=yes,
axesunits=yes,
xunit=Year,
yunit=Number of graduates
(thousands)][
data={\edudataone},
xlabels={\yearlabelstwo}]

It will be fantastic to get some feedback on this from the original authors
and also next steps to add this across all the relevant charts.

Thank you,

[NTG-context] Best way to apply a fill-pattern to a closed shape?

[Ramkumar KB via ntg-context]

Hello List,

I have a use case to apply a particular pattern to a closed shape. I am
using Metapost for the figures.

After some research this package seems to quite good, in terms of having
all the patterns normally used -  https://ctan.org/pkg/minim-hatching

But I could not figure out how to use this with ConTeXt. Or maybe there is
already a better way to do this in ConTeXt and am missing that trick.

Any tips would be really helpful.

Thank you.

Ramkumar

[NTG-context] Handling of negative values in the statistical-charts?

[Ramkumar KB via ntg-context]

Dear List,

I have been exploring the use of the awesome statistical-charts
 module. So first of all, a
big thanks to the authors of the same.

I seem to have hit a snag when it comes to handling of -ve values. In my
example (attached tex & pdf), the y-axis labels and the grids do not seem
to be working on the -ve side (also, able to flip labels above x-axis for
-ve values). This seems to be the case of column charts and bar charts (and
I will test this for the other types of charts also).

If this is a more generic issue across all the types, then I can contribute
towards enhancing it (as any charts module should handle -ve values). Any
tips or pointers would be really helpful.

Thank you very much.

Hans,

To close this thread, both poppler and exiftool worked properly after I
upgraded to the latest version (details below). I will add a section in the
wiki about these tools, as they are mighty useful when working with PDFs.

mtx-context | ConTeXt Process Management 1.04 mtx-context |
mtx-context | main context file:
/home/tex/texmf-context/tex/context/base/mkiv/context.mkiv mtx-context
 | current version: 2021.08.10 12:42 mtx-context | main context file:
/home/tex/texmf-context/tex/context/base/mkxl/context.mkxl mtx-context
 | current version: 2021.08.10 12:42

Thanks again!

Re: [NTG-context] Both pdfinfo & exiftool have trouble with 1.0.4 but works with 1.0.3

[Ramkumar KB via ntg-context]

Hans,

Thanks for the feedback. I will update to the latest version and run some
tests again.

mtxrun does not list the custom attributes unlike the others. From our
(limited) experience, mutool / poppler / exiftool all excel in different
areas. Dealing with different tools and keeping them upto date is
something we have internalized.

We did observe that mutool did not give errors with version 1.0.4 but
others did. In the ConTeXt development workflow, are there any tests with
such external tools (to possibly catch regression issues)?

We have experienced (reasonable) success with tools like diff-pdf
<https://vslavik.github.io/diff-pdf/> to catch regression in our workflow.

Thank you as always!

best regards,
Ramkumar

[NTG-context] Both pdfinfo & exiftool have trouble with 1.0.4 but works with 1.0.3

[Ramkumar KB via ntg-context]

Hi,

We use PDF tools like mutool, pdfinfo (from poppler) and exiftool in our
workflow (once the PDFs are created by ConTeXt).

But looks like we have hit upon some regression issue between 1.0.3 and
1.0.4 versions. Both pdfinfo (from poppler) and exiftool are able to read
PDFs created from 1.0.3 but have trouble reading PDFs created with 1.0.4.
Please see below logs for details.

Our 1.0.4 is from April-2021. We will try to upgrade to the latest 1.0.4
and try again.

Hello,

Looks like the file `symb-imp-was.mkiv` is missing from the path -

\tex\texmf-context\tex\context\base\mkiv

Thank you for any tips or pointers.

Wolfgang,

Thank you very much for the information. Yes, this was the trick I was
looking for.

I haved added this information in the Wiki -

Hope it is accurate enough.

Thank you once again!

[NTG-context] Natural tables | 2 tables in a page seem to interfere with each other?

[Ramkumar KB]

Hi,

I have 2 "natural tables" in one page and it appears that I have to
(manually) reset the columns in the second table, for those columns that I
had set specific width. See the example below -

Maybe I am missing a trick or two - or this indeed is the desired behavior?
Thank you very much.

\setupTABLE[r][each][height=0.5cm,frame=on]
\setupTABLE[c][each][width=0.6cm]
\setupTABLE[r][1][height=0cm,topframe=off] \setupTABLE[c][1][width=5cm]
\setupTABLE[c][4,7][width=3cm] \bTABLE ... \eTABLE
\setupTABLE[r][each][height=1.3cm,topframe=on]
\setupTABLE[c][each][width=1.7cm]
\setupTABLE[c][1,4,7][width=1.7cm] %This is to reset from the previous Table
\setupTABLE[r][1][height=0cm,topframe=off]
\setupTABLE[c][2][width=0.3cm,frame=off] \bTABLE ... \eTABLE

Re: [NTG-context] new lmtx

[Ramkumar KB]

Hans,

Thank you for the new release.

I have to mirror the installer files (see below list) at
http://lmtx.pragma-ade.com inside my corporate as the site is blocked. So
whenever a new release is announced in this list, do I just replace the
*texmf-context.zip* (or do I have to replace or some all the below files)?

ConTeXt installer files for Win64:

   - tex/status.tma
   - tex/texmf.tma
   - tex/texmf-context.tma
   - tex/texmf-win64.tma
   - texmf.zip
   - *texmf-context.zip*
   - tex/texmf-win64/bin/context.exe
   - tex/texmf-win64/bin/context.lua
   - tex/texmf-win64/bin/luametatex.exe
   - tex/texmf-win64/bin/luatex.exe
   - tex/texmf-win64/bin/mtxrun.exe
   - tex/texmf-win64/bin/mtxrun.lua


Thank you for the tips, as always.

Best regards,

[NTG-context] Adding Custom PDF Property

I am looking for a way to add custom PDF properties to the document.

>From the docs, I can see how to add standard properties (a.k.a headers)
like Title, Author, Subtitle and Keywords -
https://wiki.contextgarden.net/Interaction#PDF_Headers

But I would like to add my own custom Name-Value properties (similar to

open the document in Adobe Reader).

Thank you for the help,

Re: [NTG-context] ConTeXt Linux installation issues (due to GLIBC dependency) - Solved!

[Ramkumar KB]

Hello All,

This turned out to be an issue with the texmf-context.zip file version
mismatch. I updated to version 1.04 and was able to install successfully!

However, I would like to contribute a section to Wiki on how to install
ConTeXt in Linux machines which does not have the proper GLIBC version.
This is especially true with RHEL 7.x versions - which is still the
majority installation in companies & institutions with RHEL subscription.

The section will cover GLIBC 2.24 install, patchelf utility and the changes
needed to ConTeXt install scripts for such an installation.

How can I go about contributing to the wiki?

Thank you,
Ramkumar

[NTG-context] ConTeXt Linux installation issues (due to GLIBC dependency)

Hello All,

I am having a situation where I have to install and run Context in a Linux
machine but the machine(s) have only RHEL 7.6 (which comes with only
GLIBC_2.17).

GLIBC_2.23. Therefore, I did the following work around and it almost worked

Any tips or suggestions to try would be indeed very helpful. Thanks so much

[Ramkumar KB]

Hans,

Thank you for the suggestions. Let me try them out and feedback back to you
(as the batch set-up involves > 10,000 docs).

Best,
Ramkumar

Re: [NTG-context] Running mtxrun in a continuous batch mode

[Ramkumar KB]

Hans,

Thank you so much for the kind response.

Apologies that I was not very clear in my initial query. I have -

   1. MyStatement.tex, with all the necessary fonts, static text, images,
   header, footer etc
   2. MyStatement.tex reads from a JSON file for certain sections of the
   document for the dynamic content
   3. context MyStatement.tex produces MyStatement.pdf

How do I do the above steps 1 to 3 in a continuous fashion such that -

   - Output is MyStatement_1.pdf (reads from data_1.json), MyStatement_2.pdf
   (reads from data_2.json) and so on
   - The tex processing is fast as fonts etc are loaded once (as the Tex
   template is same for all the MyStatement_n.pdf)

>From the sample code that you gave, I get a hint that this can be possibly
done using ConTeXt Lua Document approach. Is this correct?

Thank you once again,

Best,
Ramkumar

[NTG-context] Running mtxrun in a continuous batch mode

[Ramkumar KB]

Hello,

I am trying to run mtxrun in a batch process and read the available
documentation here -
https://wiki.contextgarden.net/Running_ConTeXt_without_a_shell

My usecase is being able to create PDF docs based on the input data that
comes in a JSON format (in a continuous batch process). In ConTeXt, thanks
to the Lua engine, I am able to inject a JSON read from a file - and use
the JSON in the tex file (here variable `tab` holds the JSON).

How do I make this as a continuous webservice - in comes JSON and out comes
the PDF ?

\startluacode
require("test-json")
\stopluacode

The name of the document is \ctxlua{tex.print(tab['documentName'])}

Any tips or pointers would be much appreciated.

Thank you,
Ramkumar

Re: [NTG-context] Asymmetrical Column layout leads to an extra blank page (Solved!)

[Ramkumar KB]

Hello,

I managed to resolve the issue - which turns out bcos I had 2 back2back
columnset definitions. So instead, I combined them into 1 and the result
was ok.

*Before (leads to blank page or page with symmetrical columns):*

\definecolumnset[2col][n=2, distance=3.5mm, page=no]
\setupcolumnset[2col:1][width=.65\makeupwidth]
\setupcolumnset[2col:2][width=.35\makeupwidth]

\definecolumnset[3col][n=3, page=yes]
\setupcolumnset[3col:1][width=.25\makeupwidth]
\setupcolumnset[3col:2][width=.30\makeupwidth]
\setupcolumnset[3col:3][width=.45\makeupwidth]

\startcolumnset[2col]
...
\stopcolummnset

\startcolumnset[3col]
...
\stopcolummnset

*After (gets the desired result):*

\definecolumnset[summary][nleft=2, nright=3, distance=3.5mm, page=no]
\setupcolumnset[summary:1][width=.65\makeupwidth]
\setupcolumnset[summary:2][width=.35\makeupwidth]
\setupcolumnset[summary:3][width=.25\makeupwidth]
\setupcolumnset[summary:4][width=.30\makeupwidth]
\setupcolumnset[summary:5][width=.45\makeupwidth]

\startcolumnset[summary]
...
\stopcolummnset

Best,

[NTG-context] Asymmetrical Column layout leads to an extra blank page

[Ramkumar KB]

Hello All,

I am new to this community and am really excited about the possibilities
with ConTeXt.

My question is related to the thread -
https://www.mail-archive.com/ntg-context@ntg.nl/msg92767.html (the
suggested solution did not work, unfortunately)

After trying out various options, I am faced with these 2 (sub-optimal)
choices -

   1. Extra Blank page with Asymmetric Columns in the next page (with the
   \subject{} uncommented)
   2. No Blank page with Symmetric Columns (with the \subject{} commented)
   3. page=yes / no - does not work (same outcome as above)

I am not sure the role of \section or \subject in this matter (seems to be
somehow interfering with asymmetrical columnset).

\usemodule[newcolumnsets]
...

% \subject{} \definecolumnset[soi1][n=3, distance=3mm, page=yes]
% \definecolumnset[currency][n=3, page=yes]
\setupcolumnset[soi1:1][width=.25\makeupwidth]
\setupcolumnset[soi1:2][width=.30\makeupwidth]
\setupcolumnset[soi1:3][width=.45\makeupwidth]

Any tips, help or pointers would be greatly appreciated. If not for
columnset, is there any other way to get this type of layout?

Thank you,
