Language goodies -- hard line break the algorithm?
by denis.maier＠ub.unibe.ch 12 May '21

12 May '21

Hi, testing the new language goodies feature for ligature prevention, I found that hard line breaks seem to interfere somehow with the ligature prevention mechanism: ========================== \setuplanguage[de][ goodies={lang-de.llg}] \startlanguageoptions[de] auf|jubeln \stoplanguageoptions \mainlanguage[de] \definefontfeature[default][default][dlig=yes,liga=yes] \definefontfamily[times][rm][Times New Roman] \setupbodyfont[times] \starttext aufjubeln aufjubeln\\ auffliegen auffliegen\\ begrifflich begrifflich\\ \stoptext ====================== Best, Denis

Ligatures blocking -- why block unspecified ligatures?
by denis.maier＠ub.unibe.ch 12 May '21

12 May '21

Hi, I just ran into an issue with the \blockligatures mechanism. For some reason, the following examples replaces ffi with f|fi and ffl with f|fl although I have not specified them in \blockligatures: ============================================== \definefontfeature[default][default][dlig=yes,liga=yes] \definefontfeature[default:block][default][blockligatures=yes] % block certain ligatures globally, but not f|fl, f|fi \blockligatures [ft,fft,fj,ffj,fk] \definefontfamily[times][rm][Times New Roman] \startbuffer[test] fj\\ ffi\\ ffl\\ ff\\ fi \stopbuffer \starttext \getbuffer[test] \definedfont[Serif*default:block] \getbuffer[test] \switchtobodyfont[times] \getbuffer[test] % With Times New Roman, we can even see the bars in the output \definedfont[Serif*default:block] \getbuffer[test] \stoptext ================================== What am I missing? (I am trying to block certain ligatures globally, ie. ft,fft,fj,ffj,fk, but fi, ffi, fl, fll are being dealt with in the language goodies file.) Thanks for your help, Denis

Include PDF pages
by MANUEL GONZALEZ SUAREZ 12 May '21

Hello everybody: My query is as follows: in LaTeX there is the package "pdfpages" (https://www.ctan.org/pkg/pdfpages) that allows pages from a PDF file to be included in a TeX document. Is there a similar procedure that works in ConTeXt? Thanks. M. González.

KeenWrite 2.0
by Thangalin 11 May '21

11 May '21

Happy to announce that invoking ConTeXt from KeenWrite is now possible. Here's a screenshot showing three different PDFs compiled from the same plain text document: https://github.com/DaveJarvis/keenwrite/blob/master/docs/screenshots.md#pdf… Here are the installation instructions for ConTeXt (basically, make sure that the "context" executable can be found in the system PATH): https://github.com/DaveJarvis/keenwrite/blob/master/docs/typesetting.md KeenWrite downloads: https://github.com/DaveJarvis/keenwrite#download Stay safe everyone!

Adjusting parameters for a single page
by denis.maier＠ub.unibe.ch 11 May '21

11 May '21

Hi everyone, I know it is possible to make local changes by enclosing text in \start \stop pairs to make local changes. Then, there are also commands that only affect the next/current paragraph, such as \looseness. But is there a similar mechanism for page-layout changes? For example your penalty settings allow widows and orphans, but on one particular page you want to change the penalties. Or, you use \setupalign[height], but on one page you want to use \setupalign[bottom] instead. Is there a way to do this ? Best, Denis

simpleslides gives 'input stack overflow'
by Adam Reviczky 11 May '21

11 May '21

Hi, With the latest luatex change from https://github.com/TeX-Live/luatex/commit/1566b63b338abbe38ed839fac9f2022eb… (and MKIV 2021-05-09 17:14:00) I get an input stack overflow: simpleslides > loading style Boxed system > command '\NormalHeight' is already defined system > command '\NormalWidth' is already defined system > command '\PictureFrameHeight' is already defined system > command '\PictureFrameWidth' is already defined close source > level 4, order 8, name '/usr/share/texmf/tex/context/third/simpleslides/s-simpleslides-Boxed.tex' close source > level 3, order 8, name '/usr/share/texmf/tex/context/third/simpleslides/t-simpleslides.mkiv' fonts > bodyfont '24.0414pt' is defined (can better be done global) metapost > initializing instance 'metafun:1' using format 'metafun' and method 'default' metapost > loading 'metafun' as '/usr/share/texmf/metapost/context/base/mpiv/metafun.mpiv' using method 'default' metapost > initializing number mode 'scaled' input stack overflow mtx-context | fatal error: return code: 256 MWE from the documentation: \usemodule[simpleslides][style=Boxed] \setupTitle[title={Title of the presentation},author={Name of authors},date={Date of presentation}] \starttext \placeTitle \SlideTitle{The first slide} Write whatever you want. \SlideTitle{The second slide} Continue writing. \stoptext Does that mean the simpleslides module has some recursion problems? I have tried a couple of themes but getting the same error. Adam

Tracking overfull/underfull vboxes, widows/orphans
by denis.maier＠ub.unibe.ch 10 May '21

10 May '21

Hi, some time ago Hans has added these trackers for overfull/underfull hboxes: I'm wondering if there is something similar for vertical boxes? I've found these trackers: builders.vspacing builders.vpacking builders.page_vspacing builders.collect_vspacing But I don't really understand what they do. (Yes, I've tried them.) Maybe someone can shed some light on this ? (RTFM is a perfectly fine answer, just need to know which manual...) Then, would it be possible to add a tracker for widows/orphans? (Or even for prevented widows/orphans ?) Denis

underscore hyphenation not working
by Pablo Rodriguez 10 May '21

10 May '21

Hans, some time ago, you provided me with the following code to hyphenate sha with underscore: \startluacode function document.addfunnyhyphen(tfmdata) local underscore = utf.byte("_") local char = tfmdata.characters[underscore] if not char then return end tfmdata.characters[0xFE000] = { width = 0, height = 0, depth = 0, commands = { { "right", -char.width }, { "down", char.depth }, { "slot", 1, underscore }, } } end utilities.sequencers.appendaction("aftercopyingcharacters", "after","document.addfunnyhyphen") local shared = { start = 1, length = 1, before = utf.char(0xFE000), after = nil, left = false, right = false, } local all = table.setmetatableindex({ }, function(t,k) return shared end) languages.hyphenators.traditional.installmethod("sha", function(dictionary,word,n) return all end) \stopluacode \definehyphenationfeatures [sha] [characters=all, alternative=sha, righthyphenchar="FE000] \sethyphenationfeatures[sha]% \setuphyphenation[method=traditional]% \starttext \hsize\zeropoint \tt abcde \stoptext I’m afraid that it isn’t working as expected with current latest from 2021.05.06 23:35. I wonder whether this might be caused by a bug or the code should be adapted to current latest. Many thanks for your help, Pablo -- http://www.ousia.tk

The following: \starttext $s''$ %or $s^{\prime}$ \stoptext gives a too high symbol in ConTeXt LMTX 2021.05.06 23:35. ConTeXt MkIV isn't affected for such an issue. Jairo

Update setpath to set the path
by Thangalin 10 May '21

10 May '21

Thoughts on updating the setpath.bat file to persist setting the path? Here's an updated version that sets the system environment variable while preserving the existing unexpanded PATH value: rem SOF echo off set OWNPATH=%~dp0 set PLATFORM=mswin if defined ProgramFiles(x86) set PLATFORM=win64 if "%PROCESSOR_ARCHITECTURE%"=="AMD64" set PLATFORM=win64 if exist "%OWNPATH%tex\texmf-mswin\bin\context.exe" set PLATFORM=mswin if exist "%OWNPATH%tex\texmf-win64\bin\context.exe" set PLATFORM=win64 echo %PATH% | findstr "texmf-%PLATFORM%" > nul rem Only update the PATH if not previously updated if ERRORLEVEL 1 ( set Key="HKLM\SYSTEM\CurrentControlSet\Control\Session Manager\Environment" set "CurrPath=" for /F "USEBACKQ tokens=2*" %%A in (`reg query %%Key%% /v PATH`) do ( if not "%%~B" == "" ( rem Preserve the existing PATH echo %%B > currpath.txt rem Update the current session set PATH=%PATH%;%OWNPATH%tex\texmf-%PLATFORM%\bin rem Change the PATH environment variable setx PATH "%%B;%OWNPATH%tex\texmf-%PLATFORM%\bin" /M ) ) ) rem EOF Another possibility would be to define CONTEXT_HOME as an unexpanded value added to both the system environment variables and the PATH variable. For example (haven't tried it): setx CONTEXT_HOME "%OWNPATH%tex\texmf-%PLATFORM%\bin" setx PATH "%%B;%%CONTEXT_HOME%%" The advantage with this pattern is that subsequent updates need only check for CONTEXT_HOME and change its value without having to worry about PATH parsing, which can be hairy. Yet another option to consider is changing the value for only the existing user, rather than system-wide. Perhaps two different batch files? The reason for this change is because the Windows installation instructions (on the wiki) are incomplete: technically, the user must run setpath.bat for each new session. This implies that any third-party program that wants to make use of ConTeXt on Windows would have to communicate said fact to the user, or let the user set the full path to ConTeXt within the third-party program. Both of these can be avoided by persisting the PATH setting across sessions. Thank you! P.S. Pasted: https://pastebin.com/qpsqXZNB
