lmtx update / teaser
by Hans Hagen 02 Mar '21

02 Mar '21

Hi, I uploaded a new lmtx. As I'm currently going through the metafun todo files I ended up at the fancy shape part (parshapes) running over multiple paragraphs and decided to provide a (kind of low level) interface that integrates that. The example code is a few decades old but still works ok (i might try to improve them a bit some day). Anyway, here is a teaser: \starttext \startuseMPgraphic{circle} lmt_parshape [ path = fullcircle scaled 136mm, offset = 2mm, bottomskip = - 1.5LineHeight, ] ; \stopuseMPgraphic \start \startshapedparagraph[list=circle,mp=circle,repeat=yes,method=cycle]% \setupalign[verytolerant,stretch,last]\dontcomplain {\darkred \samplefile{tufte}}\par {\darkgreen \samplefile{tufte}}\par {\darkblue \samplefile{tufte}}\par {\darkcyan \samplefile{tufte}}\par {\darkmagenta \samplefile{tufte}}\par \stopshapedparagraph \stop \page \start \startshapedparagraph[list=circle,mp=circle,repeat=yes,method=repeat]% \setupalign[verytolerant,stretch,last]\dontcomplain {\darkred \samplefile{tufte}} {\darkgreen \samplefile{tufte}} {\darkblue \samplefile{tufte}} {\darkcyan \samplefile{tufte}} {\darkmagenta \samplefile{tufte}} \stopshapedparagraph \stop \stoptext The interface is still somewhat rough (no grouping for instance, not a real envrionment so that might change) but seems to work ok. One can also go the tex route and say: \startparagraphshape[test] left 1mm right 1mm left 2mm right 2mm left 3mm right 3mm copy 8 left 4mm right 4mm left 5mm right 5mm left 5mm hsize 10cm \stopparagraphshape or \startparagraphshape[test] left 1mm right 1mm right 3mm left 5mm right 5mm repeat \stopparagraphshape or \startparagraphshape[test] both 1mm both 2mm both 3mm both 4mm both 5mm both 6mm both 7mm both 6mm both 5mm both 4mm both 3mm both 2mm \stopparagraphshape or \startparagraphshape[test-repeat] both 1mm both 2mm both 3mm both 4mm both 5mm both 6mm both 7mm both 6mm both 5mm both 4mm both 3mm both 2mm repeat \stopparagraphshape and use that with: \startshapedparagraph[list=test] \dorecurse{8}{\showparagraphshape\samplefile{tufte} \par} \stopshapedparagraph or \startshapedparagraph[list=test-repeat] \dorecurse{8}{\showparagraphshape\samplefile{tufte} \par} \stopshapedparagraph Some more info is in the lowlevel-paragrsph document (part of the low level series). This kind of features falls into the category 'fancy' (no one reqtested it), nice for posters and covers. It might evolve depending on needs for fancy features, but as said, it's currently a side track of metafun, so it's also in the category 'fun'. It's code for 'controlled' usage.

outputting components in their own PDFs
by Alan Bowen 01 Mar '21

01 Mar '21

I have a project-component setup and need to produce a single PDF file containing all the components as well as a PDF file for each component. The single file is easy. Is there a way to automate the generation of the PDF files for the individual components? Alan

Project Structure - inheritance rules for environments
by denis.maier＠ub.unibe.ch 01 Mar '21

01 Mar '21

Hi, I'm just having a look a project structure again. I am using the example given in the wiki: https://wiki.contextgarden.net/Project_structure, i.e., in my component I'm linking to the product, but not to the project. Now I was expecting that the component inherits the environment set in the project via the product. The wiki currently explains: "If you tex (compile) one single component (e.g. a chapter of a book) or product (e.g. one volume of a magazine), the environment file of the project is used." That does not seem to be the case here. Can anyone confirm this? Is this a bug or does the wiki needs to be revised? Best, Denis

Re: [NTG-context] Make LMTX load a custom library

The installer doesn't wipe the bin tree. In windows you can have the dll in some system path too and there's also package.extralibpath("d:/Lukas/Lua/54") or you can add stuff to the configuration file. I admit that I haven't tested that in a while (I only occasionally use(d) the mysql library but either with ffi (mkiv) or with the built in one (lmtx), not some external lua specific wrapper). The mentioned tracker shows you all the places where libs are searched.

Make LMTX load a custom library
by Lukas/ConTeXt 01 Mar '21

01 Mar '21

Hello, suppose having a custom DLL (actualy a Lua module) in: d:\Lukas\Lua\54\WinCon.dll How exactly should I alter the path specification so LMTX be able to load WinCon.dll? My trials - without success so far - are: 1. Alter LUA_CPATH before running Ctx, so something like: ---- (command line) set LUA_CPATH=d:\Lukas\Lua\54\?.dll;%LUA_CPATH% context.exe test.tex ... ---- 2. Alter LUAINPUTS before running Ctx, so something like: ---- (command line) set LUAINPUTS=%LUAINPUTS%;d:\Lukas\Lua\54\?.dll;%LUA_CPATH% context.exe test.tex ... ---- 3. Changing the path at runtime, so something like: ---- test.tex \startluacode package.cpath = package.cpath .. ";d:/Lukas/Lua/54/?.dll" require "MyLib" \stopluacode ---- But I'm still getting errors like: " ... token call, execute: ...TX/tex/texmf-context/tex/context/base/mkiv/l-sandbox.lua:180: module 'WinCon' not found: no field package.preload['WinCon'] no file 'd:\Lukas\Lua\WinCon.lua' no file 'd:\Lukas\Common\Statics\WinCon.lua' no file 'd:\Lukas\Lua\3rdParty\WinCon.lua' no file 'd:\Lukas\Lua\3rdParty\stdlib\modules\WinCon.lua' no file 'd:\Lukas\Lua\3rdParty\LuaXML\WinCon.lua' no file 'C:\Program Files (x86)\Lua\5.1\lua\WinCon.luac' no file 'd:\Lukas\Lua\Geom' ... " Surprisingly, loader tries to locate a *.lua* only, whilst here I nedd to load a .dll; and in genereal case, .lua, .luac and .dll may be required. So - how to specify the path correctly, be it on the command line or within a .tex (LMTX run-time)? Best regards, Lukas

Project structure light
by denis.maier＠ub.unibe.ch 01 Mar '21

01 Mar '21

Hi, another question regarding project structure. I want to put each chapter of a book in a component or a distinct file loaded with \input, but I don't want to have a full project structure. Just a main file and the chapters. Nevertheless, I want to load the environment file in each subfile. Is that possible or will that cause problems? Best, Denis main.tex -------------------------- \environment test \starttext \input chapter1 \stoptext -------------------------- chapter1.tex -------------------------- \environment test \starttext Some text. \stoptext --------------------------

Indenting on all TEXpages
by Jacob Kauffmann 28 Feb '21

28 Feb '21

Dear list, is it possible to enable indenting globally for TEXpage environments? Or is it recommended to create a separate environment for that purpose? Please find a MWE below. It seems to me that \setupindenting must be set explicitly for every page that needs indenting. Best, Jacob Kauffmann \setupTEXpage[width=10cm] \setupindenting[yes,medium] % not working \starttext \startTEXpage \input knuth \stopTEXpage % working \startTEXpage \setupindenting[yes,medium] \input knuth \stopTEXpage \stoptext

Bug report: \setupbackend corrupts bibliography rendering
by a badin 28 Feb '21

28 Feb '21

Dear gardeners, I'm new to ConTeXt and would like to share a possible bug with you. If I have the \setupbackend[export=example.xml,css=example.css] entry in my .tex file, then my bibliography renders in a strange way (text copied from pdf): 1 bfldcategoryarticle: [author: Andrej Arrow] [journal: MAPS] [keywords: context] [pages: 2-8] [title: The Font Name Mess] [volume: 40] [year: 2010] If I remove or comment that entry out, then the bibliography renders OK (copy from pdf): 1 A. Arrow, “The Font Name Mess”, *MAPS *40, 2-8, 2010. my .tex source is: % \setupbackend[export=example.xml,css=example.css] \usebtxdataset[default][ref.bib] \starttext \cite[Arrow][Arrow] \placelistofpublications \stoptext my ref.bib file: @ARTICLE{Arrow, author = {Andrej Arrow}, title = {The Font Name Mess}, journal = {MAPS}, year = {2010}, volume = {40}, pages = {2-8}, keywords = {context}, } Hope this helps, best, Andrej -- Andrej Badin +31 6 82 23 50 33

Incorrect css reference in exported html file
by Aditya Mahajan 28 Feb '21

28 Feb '21

Hi, This message is prompted by a bug report for t-vim (https://github.com/adityam/filter/issues/43) but the issue is more general. Whenever, `cssfile` in `\setupexport` points to a file now in $PWD, the reference to the file in the exported CSS is incorrect: Consider the following directory tree: test.tex styles/mystyle.css where test.tex is: ``` \setupbackend[export=yes] \setupexport[cssfile=styles/mystyle.css] \starttext \startparagraph This is a test \stopparagraph \stoptext ``` and styles/mystyle.tex is (the content doesn't matter, listing it for completeness): ``` paragraph, p, div.paragraph, div.p { color : red ; } ``` I am attaching a zip file for convenience. When I compile the above file, I get (selective lines from output) ``` backend > export > copying styles/mystyle.css ... backend > export > adding css reference 'styles/styles/mystyle.css' ``` Indeed, the styles/mystyle.css file is copied to `test-export/styles/mystyle.css` but the reference in `test-export/test-export-div.html` is: ``` <link type="text/css" rel="stylesheet" href="styles/styles/mystyle.css" /> ``` Note the repeated styles/styles. What is happening is that while copying the file, context is using (in back-exp.lua): local source = addsuffix(cssextra[i],"css") local target = joinfile(stylepath,basename(source)) while for reference, context is using: result[#result+1] = replacetemplate(csspreamble, { filename = cssfile }) extras[#extras+1] = replacetemplate(cssheadlink, { filename = cssfile }) Shouldn't the last part be filename=basename(source) to get the right name? Without that whenever the value of cssfile is a file in another directory, the css reference in the exported html file will be incorrect. In case anyone is interested, this manifests in t-vim as follows. The t-vim module includes a pre-generated css file which provides the color and style values for the default color schemes. The module provides a macro \vimcssfile, which is the complete path of the file (basically the value of `resolvers.resolve("full:vimtyping-default.css")`). The intended usage is: \usemodule[vim] \setupbackend[export=yes] \setupexport[cssfile=\vimtypingcssfile] ... In this case, the css file is correctly copied to the '\jobname-export/styles` directory. but the `\jobname-div.html` file contains a unusable reference: ``` ... <link type="text/css" rel="stylesheet" href="styles/opt/luametatex/texmf-modules/tex/context/third/vim/vimtyping-default.css" /> ``` In principle, I can work around this in t-vim but I think that this will impact others as well. Thanks, Aditya
