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

[Ramkumar KB]

Hi,

Thank you for the tips. Yes, I will probably write something similar (but
probably in Go  or Python
, as they are easier to maintain
in the environments that I work).

Thank you very much!

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

I had to remove these files to update from LMTX from 2020.10.20 to
version from 2020.11.05.

But I had to remove these files again to upgrade from 2020.11.05 to
2020.11.06.

I wonder whether the same happens in Windows (I haven’t checked it yet).

Just in case it helps,

Would it be possible that LMTX adds the undefined command at the end of
the tex error line? I mean something similar to:

 tex error   > tex error on line 9 in file cont-yes.mkiv: Undefined
 control sequence (vskivskip)

It would help a lot to detect wrong commands.

Many thanks for your help,

[NTG-context] color epub reader

[Hans Hagen]

Hi,

Playing with a pocketbook color epub reader (I just put some manuals on 
it):


- the colors are not bright enough, also not with lights on, why rgb and 
not cmyk (i only tested pdf)


- the viewer is buggy and freezes, color demands more mem i think, but 
after an upodate it got a bit better


- resolution not good enough (yet)

But we keep hoping ...

[NTG-context] store data in the first run for later runs?

[Pablo Rodriguez]

Dear list,

I have the following sample:

  \starttext
  \startTEXpage[offset=1em]

  \startmode[*first]
  \startluacode
  io.write(" What’s your name?")
  document.user_name = io.read()
  document_data = { "\\def\\UserName{" .. document.user_name .. "}" }
  io.savedata(tex.jobname.."_document-tmp-data.txt", document_data)
  \stopluacode
  \stopmode

  \input{\jobname_document-tmp-data.txt}
  \UserName, nice to meet you.
  \stopTEXpage
  \stoptext

This prompts user input on the first run, but I have to save to an
external file to be able to read it in next runs.

Just in case you might wonder, the actual code requires "--purgeall".

Is there no way to save that in the .tuc file for later runs?

I have tried
https://wiki.contextgarden.net/System_Macros/Key_Value_Assignments#Multi-pass_data
(as Aditya suggested to me), but runs after the first one see to empty
the data in the Lua table.

Adapting a sample from the wiki:

  \starttext

  \definedataset[somedataset]
  \startmode[*first]
  \setdataset[somedataset][wantscake=yes, wantsdeath=no]
  \stopmode

  Do you want cake? \datasetvariable{somedataset}{1}{wantscake}.\\
  BTW, do you want death? \datasetvariable{somedataset}{1}{wantsdeath}.
  \stoptext

I wonder whether there is no cleaner way to do this.

Many thanks for your help,

Pablo

Hi Jairo and Floris,

I reported a similar issue some days ago.

I think I have solved it (no extensive checking yet) by deleting the
three texmf*.tma files on the tex/ directory.

If you still have a copy of your older installation, you may try this
(but please make a backup of the older installation first).

Just in case it might help,

WHen you are in doubt you can do this:

\meaning\in

it will show you that the commands is adapting itself to math mode. 
There are a few such commands with 'clashing' names.

A variant on this is \NC which is the column separator but has a 
different meaning depending on where it's used. That one gets set to 
some meaning in environments.

Another overloaded one is \\ and it could be a space or newline or ...

Actually the last two are candidates for protectiopn against overload.

btw, users can run context with

--overloadmode=warning
--overloadmode=error

to see if their usage of commands or definitions bring conflicts. 
Currently \in is not yet protected against overload but it will be.

Hans

last month, install.sh isn't doing anything. However, when I go to Pragma
ADE's website, I can download newer releases and they work fine (e.g.
--permitloadlib works now). I'm not so picky about manual downloads, but I
think install.sh is (or was) quite better. I'm on Ubuntu 20.04, in case it
helps. Thank you very much.

Regards,

Jairo :)

[NTG-context] Problem using a TTF font

[ntg]

This, I'm certain, used to work with an LMTX from the beginning of the year but 
I've upgraded to "ConTeXt  ver: 2020.11.05 23:01 LMTX  fmt: 2020.11.6  int: 
english/english" and now it doesn't. 

I have a single .tex file in a directory, containing:

---begin---
\definefont [TwelveC] [file:Bondi12CPlus.TTF at 14pt]
\starttext
Keycaps: \TwelveC 123.45 \tf and back again
\stoptext
---end---

In the same directory I have the TTF font file which can be obtained from 
. It is calculator keycap images for use 
in documentation.

In the PDF I get just blank space where the keycaps should be and Adobe 
Reader's document info seems to think there is only one font in the file i.e. 
the keycap font didn't get embedded. However, the console output includes the 
lines:

mkiv lua stats  > result saved in file: 12C_test.pdf, compresslevel 3, 
objectcompresslevel 1
mkiv lua stats  > loaded patterns: en::1, load time: 0.000
mkiv lua stats  > loaded fonts: 3 files: latinmodern-math.otf, 
lmroman12-regular.otf, bondi12cplus.ttf
mkiv lua stats  > font engine: otf 3.111, afm 1.513, tfm 1.000, 8 instances, 3 
shared in backend, 3 common vectors, 0 common hashes, load time 0.132 seconds 
mkiv lua stats  > font embedding time: 0.006 seconds, 2 fonts

which suggests LMTX thinks it loaded the font but decided not to embed it for 
some reason.

I'm probably doing something silly since it's been several months since I last 
looked at this but I can't see what I might be doing wrong :-(  so any and all 
help much appreciated.

PS: The font installs and displays in MacOS fine.

I've also tried
  \definefont [TwelveC] [Bondi12CPlus at 14pt]
and that fails the same way.

If one of the \index{D...} lines is commented in the following example, the 
last D entry goes into the second column, the columns get balanced, and the 
second line of the last K entry is broken to the next page.
If you uncomment that line, it looks as intended (no balancing, full left 
column).
What’s wrong? Can I influence this e.g. with penalties?

Docs say otherwise.
Without argument, I don’t get an error, but also nothing happens.

Here is a script which does this for general tasks:

It is also possible to build something on top of inotifywait on linux.

I don't think \showinjector needs an argument. My MWE when I was looking at
this has just \showinjector after the register definition but before the
\setinjector[...] commands.

It doesn’t work for me:

lua error   > lua error on line 24 in file inhalt/99anhang.tex:

registered function call [421]: 
...-06/tex/texmf-context/tex/context/base/mkiv/typo-inj.lua:63: attempt to

Regardless what I try as parameter of \showinjector (e.g. register, index, my 
own registers, one or a list) and where (in the environment or before 
\placeregister), I always get this error.

Bug?

[NTG-context] index issues

[Henning Hraban Ramm]

Hello again,

still struggling with indexes.

(1)
\setupregister’s before and after go around the indicator.
e.g. \setupregister[][indicator=no,after={XX}]
never shows that XX, since after is only used after the indicator, while before 
also works without.

I was hoping for a hook at the end of a section (to add \testcolumn, \blank 
etc. to work around no.2). Is there any?


(2)
Page/column breaking is odd in that the preferred breaking point seems to be 
one entry too early, i.e. the last entry of one letter end up in the next 
column and the previous column is one line too short.
It doesn’t change with balance=yes/no.

E.g.

p.1
A   A
A   A
A
A   B
A   B
A   B
A   !?

p.2
B   C
B   C
B   C
C
C   
C   D
C   D


(3)
(How) can I otherwise influence page/column breaking? E.g.
- always keep multi line entries together
- break before or after some entry


(4)
Is it possible to combine entries from \index and \startregister[index]?

If I use \start/stopregister and have the same index entry within the range or 
on the same page, I get duplicate pages or page ranges, like 10-12 from 
\startregister and additionally 11, 12-13 from \index entries, makes at the 
moment 10-12, 11, 12-13 instead of just 10-13.



I’ll prepare MWEs, but maybe you can answer some of these without?

Thank you in advance,

Hraban

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

[Ramkumar KB]

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).
>From the initial error logs it appears that Context needs minimum
GLIBC_2.23. Therefore, I did the following work around and it almost worked
! (there were no more GLIBC_2.23 errors and installation was progressing
well...) , till it did not... :-(

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

*Work Around* -
Manually installed GLIBC_2.23 as per the instructions here - in my own
directory where I have full access -
https://gist.github.com/carlesloriente/ab3387e7d035ed400dc2816873e9089e

Used the patchelf utility - https://anaconda.org/conda-forge/patchelf

*Changed the following Context install files*
*install.sh (just before running mtxrun)*

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

[thierry horsin]

Hi Ramkumar,

Maybe you could have some scripts that check when the JSON file is 
modified and if so launches the compilation. I did that sort of script 
in order to have a continuous compilation process by checking every 
second if my current .tex file is modified.

i'd just write a script that calls context like

context mystatement.tex --myjsonsection=1 --batch
context mystatement.tex --myjsonsection=2 --batch
context mystatement.tex --myjsonsection=3 --batch

etc .. maybe --once if no multipass is needed, or --runs=2 if you
know
how many runs are needed

to stay in a run and kind of restart is asking for troubles
because what
should be reset? of course i could context make do that buit it
doesn't
pay off

an alternative that you generate one document with all statements and
use mutool to split of the pages

but anyway, nowadays machines are fast enough to have separate
runs (and
one can run them in parallel)

[NTG-context] lmt_axis

[thierry horsin]

Dear list,

I am currently trying to test the lmt_axis exemple in luametafont.pdf. I 
am working on linux/ubuntu. The exemple leads to compilation errors 
below. The current version of context that I am using is from last july.


I have succeeded with other examples, e.g. surfaces or lmt_text

Any insight about this issue ?

Many thanks.

Re: [NTG-context] math symbol for "is an element of"

In this particular case, as Wolfgang pointed out, \in actually does work to get 
the desired symbol in math mode. But it is good to know how to use text 
substitutions too.

WHen you are in doubt you can do this:

\meaning\in

it will show you that the commands is adapting itself to math mode. 
There are a few such commands with 'clashing' names.


A variant on this is \NC which is the column separator but has a 
different meaning depending on where it's used. That one gets set to 
some meaning in environments.


Another overloaded one is \\ and it could be a space or newline or ...

Actually the last two are candidates for protectiopn against overload.

btw, users can run context with

--overloadmode=warning
--overloadmode=error

to see if their usage of commands or definitions bring conflicts. 
Currently \in is not yet protected against overload but it will be.
