Shaded large letters in LMTX
by Keith McKay 02 Mar '21

02 Mar '21

Hi All, Is it possible to get the fill colour in lmt_outline[] to be shaded between two colours like in the lmt_shade[] command? It would be a nice effect for large letters or words. Best Wishes Keith McKay Hamilton, Scotland

Setuptolerance vs setupalign
by denis.maier＠ub.unibe.ch 02 Mar '21

02 Mar '21

Hi, I've just noticed that it's possible to do \setupalign [tolerant,stretch] and \setuptolerance [tolerant,stretch] Are these equivalent? Will this here have the desired effect? \setuptolerance[tolerant,stretch] \setupalign[hz,hanging] Or will \setupalign overwrite the tolerance settings? Best, Denis

outputting components in their own PDFs

Denis— Many thanks for your explanation. It works very well in my separating components (chapters) and is going to save me a lot of time. Thanks too to Hans. And my apologies for missing the earlier discussion: my internet access and email has been very flakey of late and I know that I have lost messages. In fact, I found Denis’s reply and the earlier exchange by going to the list Archive. All best, Alan

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 --------------------------
