unprotecting when defining in Lua
by Pablo Rodriguez 29 Apr '24

29 Apr '24

Dear list, I have the following sample: \starttext \startluacode function document.test(str) context(str) end interfaces.definecommand { name = "testing", protected = false, macro = document.test, } \stopluacode \meaningfull\testing \def\test#1{#1} \meaningfull\test \stoptext Which is the right way to use "interfaces.definecommand" to get a simple command as in standard TeX? I mean, no a non \permanent or non \protected command. Many thanks for your help, Pablo

ConteXt commands in an rtl environment
by Alan Bowen 29 Apr '24

29 Apr '24

I am having trouble entering ConteXt commands in an rtl language, in this case Hebrew. How does one make the last(left hand) letter of the Hebrew word אשר a superscript? My experiments with \high{...} have not been successful so far in part, I think, because I have not got the brackets right. Any tips or pointers will be gratefully received. Alan

Why Difference Between \placefloat and \definefloat
by urban.m＠ca.rr.com 29 Apr '24

29 Apr '24

I swear I used to understand this stuff. I plead old age. Why do I get two different results from the float placements here: definefloat[mysidebar][mysidebars] setupfloat[mysidebar][leftmargindistance=-.25in,rightmargindistance=-.25in,outer,none] defineframedtext [sidebartext] [width=.4textwidth,bodyfont=small,corner=round,background=color,backgroundcolor=lightgray,align=flushleft] starttext This is a bit of text placefloat[sidebar][leftmargindistance=-.25in,rightmargindistance=-.25in,outer,none]{}{ startsidebartext This is a short sidebar stopsidebartext } And something to follow. A bit of text placemysidebar{}{ startsidebartext This is a short sidebar stopsidebartext } And something to follow. stoptext

Re: statistical charts module re-published

Hi Tomáš, thank you, I updated the information at https://codeberg.org/fiee/context-statistical-charts and also published the new version to https://modules.contextgarden.net (i.e. installation with "mtxrun --script install-modules --install statistical-charts" will now install the current version).

Re: QR Code

Catching up on an earlier thread by Ursula and Hraban, I'm also experienceing problems with \usemodule[zint] while \usemodule[t-zint] works fine. Running on macOS (ConTeXt ver: 2024.04.01 08:59 LMTX fmt: 2024.4.28). The issue seems somewhat unrelated to ConTeXt on first glance (??) if this is helpful. My code stopped working after I updated the OS (to Sonoma) and my homebrew cellar (to zint 2.13.0) while keeping a ConTeXt version from 2022 which compiled the barcodes perfectly fine before these updates. This being said, the newer ConTeXt version doesn't resolve the issue. Observations: 1) Zint (and Inkscape) is in my PATH and correctly sym-linked as specified in the wiki (~/tex/texmf-osx-64/bin/lib/luametatex/zint/libzint.so <http://libzint.so/>). However, the library was (still) not fount after mtxrun --generate [This seems an odd, but unrelated problem] 2) So, I hardcoded libfile in libs-impzint.lmt to local libfile = "/usr/local/Cellar/zint/2.13.0/lib/libzint.dylib" 3) Running the wiki example: \usemodule[m-zint] \starttext \barcode[alternative=isbnx, text=9783865419026, width=4cm] \barcode[alternative=qrcode, text={https://wiki.contextgarden.net}, width=3cm] \barcode[alternative=maxicode, text={test}, width=3cm] \stoptext * With \usemodule[m-zint], I correctly get: zint --barcode=qrcode --output="zint-qrcode-495165e08dbc5ce650aaaf13caa2229f.eps" --input="zint-qrcode-495165e08dbc5ce650aaaf13caa2229f.tmp" zint --barcode=maxicode --output="zint-maxicode-098f6bcd4621d373cade4e832627b4f6.eps" --input="zint-maxicode-098f6bcd4621d373cade4e832627b4f6.tmp" [Barcodes show up as expected] * With \usemodule[zint], no success: optional > using library '/usr/local/Cellar/zint/2.13.0/lib/libzint.dylib' zint > something went wrong: invalid result vector zint > something went wrong: invalid result zint > something went wrong: invalid result vector Maybe this is helpful to pinpoint the issue?

I don't think that 'sidebar' has much to do with it. The part that is not working as expected is the 'mysidebar', which is not getting the 'outer' location, nor the 'none' captioning that I get with placefloat. setupfloat[mysidebar][leftmargindistance=-.25in,rightmargindistance=-.25in,outer,none] defineframedtext [sidebartext] [width=.4textwidth,bodyfont=small,corner=round,background=color,backgroundcolor=lightgray,align=flushleft] starttext This is a bit of text placefloat[newsidebar][leftmargindistance=-.25in,rightmargindistance=-.25in,outer,none]{}{ startsidebartext This is a short sidebar stopsidebartext } And something to follow. A bit of text placemysidebar{}{ startsidebartext This is a short sidebar stopsidebartext } And something to follow. stoptext

Define a new command that inherits from multiple other command options
by ai2472206007＠yeah.net 28 Apr '24

28 Apr '24

hi! I'm new to ConTeXt. I want to define a command with sidenote function. This [setupsidenote] command inherits the options of [setupmargindata], [setupcounter] and [setupframed]. just like [setupenumeration] inherits the option of [setupcounter]. I've defined the following sidenote command by searching, and I know how to define a new option for it. But what I don't know is how to get it to inherit the options of other commands and perform these features correctly. Any clue is warmly welcome. ``` % macros=mkvi \unprotect \installnamespace {sidenote} \installcommandhandler \????sidenote {sidenote} \????sidenote \setupsidenote[ align=, conversion=n, way=bytext, style=, ] \definecounter [SidenoteMarkNumber] [prefix=no] \definemargindata [SidenoteContent] [outer] [margin=margin,width=\outermarginwidth] \setupmargindata [SidenoteContent] [stack=yes,style=\it] \def\sidenotemark{\rawcountervalue[SidenoteMarkNumber]} \def\convertsidenotemark#1{\high{\convertnumber{#1}{\sidenotemark}}} \def\sidenote{\dosingleempty\dosidenote} \def\dosidenote[#1]#2{% \getparameters[SMsidenote] [align=\sidenoteparameter{align}, conversion=\sidenoteparameter{conversion}, way=\sidenoteparameter{way}, #1]% \setupcounter [SidenoteMarkNumber] [#1] \incrementcounter[SidenoteMarkNumber] \convertsidenotemark{\SMsidenoteconversion}% mark in text \SidenoteContent[#1]{\setscript[hanzi]\setup[\SMsidenotealign]% \convertsidenotemark{\SMsidenoteconversion}% mark with note #2 }} \protect \starttext 天地玄黄，宇宙洪荒。日月盈昃，辰宿列张。寒来暑往，秋收冬\sidenote[align=flushleft] {天地玄黄，宇宙洪荒。} \stoptext ```

How to make superscript text match footnote mark formatting?
by Joel 27 Apr '24

27 Apr '24

\starttext test\high{1}test\footnote{some text} \stoptext How can I create a superscript number that has exactly the same formatting as a footnote, but which won't create a footnote. I tried \high{}, which I believe should be the way to superscript text, but if you compile this, you can see the first "1" and second "1" have entirely different formatting. How do I make the first one have the same exact formtating as the real footnote? --Joel

wrong spacing after command with optional arguments
by Pablo Rodriguez 26 Apr '24

26 Apr '24

Dear list, I have the following sample: \starttext \def\MyCommand{\doquadruplegroupempty\doMyCommand} \def\doMyCommand#1#2#3#4{% \iffourthargument #4% \orelse\ifthirdargument #3% \else #2% \fi} \MyCommand{}{second}{third}{fourth},\\ \MyCommand{}{second}{third}{fourth} e,\\ \MyCommand{}{second}{third},\\ \MyCommand{}{second}{third} e,\\ \MyCommand{}{second},\\ \MyCommand{}{second} e,\\ \stoptext I don‘t know why only the command gets the space after right only when the four arguments are provided. What is wrong in my definition above? Many thanks for your help, Pablo

The graph is not visible.
by Fabrice Couvreur 26 Apr '24

Hi, I don't know if I can explain the problem I'm having. I made a project with 14 chapters. In each of them, there are graphics embedding metapost code. I proceed as follows : I compile each chapter alone with lmtx then I compile the project containing the 14 chapters. I didn't encounter any problems except with a graphic from the last chapter. It is indeed in chapter 14 but not in the project ! I give the code for this graph. Thanks.
