\type{...} as macro argument
by Sylvain Hubert 08 Nov '20

08 Nov '20

Dear List, I would like to ask how to define a command, \same, such that \same{\type{a b c}} produces the same result as its argument does \type{a b c} The naive way doesn't work because it makes all the spaces collapse: \define[1]\same{#1} I would also like to ask whether this could be achieved using the lua interface: \startluacode interfaces.definecommand { name="same", -- catcode/mode/arguments = ??? } Thanks in advance. Best, Sylvain

"page i/n" in footer
by Sylvain Hubert 08 Nov '20

08 Nov '20

Dear List, Does anyone know how to set the footer to be "page i/n" where i=current page number, n=total number of page? I've tried \setuppagenumbering[location=footer, command=\groupedcommand{page }{/\lastcounter[userpage]}] but \lastcounter[userpage] results in empty string. Thanks in advance. Best, Sylvain

issues with fonts and font effects
by Pablo Rodriguez 08 Nov '20

08 Nov '20

Hans, this sample comes from Sylvain’s message: %~ \definefontfeature[ef1][effect={width=1.0}] \definefontfeature[ef2][effect={width=}] \definefontfamily[face1][rm][gabriola] [features={default, ef1}] \definefontfamily[face2][rm][gabriola] [features={default, ef2}] \starttext \switchtobodyfont[face1]\dorecurse{100}{a b c } \switchtobodyfont[face2]\dorecurse{100}{a b c } \switchtobodyfont[palatino]\dorecurse{100}{a b c } \stoptext \setupbodyfont[palatino] or \switchtobodyfont[palatino] don’t seem to work at all. Results are different if feature ef1 is defined or not. With all features defined, paragraph width is wrong using "effect={width=1.0}". Could you check this? Many thanks for your help, Pablo -- http://www.ousia.tk

temporarily move up a section title
by Sylvain Hubert 08 Nov '20

08 Nov '20

Dear List, I'm trying to move up a section title (section b) 2cm upward: \starttext \section{a} \blank[-2cm,force]\ \section{b} \section{c} \stoptext The empty space (\ ) after the \blank is necessary here, without which the \blank does nothing. I would like to ask whether there is a less hacky way to let \blank work than the hidden space. Thanks in advance. Best, Sylvain

weird behavior of font.feature.effect
by Sylvain Hubert 08 Nov '20

08 Nov '20

Dear List, I'm confused by the result of the following example (see attached): \definefontfamily[face1][rm][gabriola][it={features:{default}}] \definefontfamily[face2][rm][gabriola][it={features:{default, effect={}}}] \definefontfamily[face3][rm][gabriola][it={features:{default, effect={width=1.0}}}] \starttext \startitemize[n, packed] \item \switchtobodyfont[face1]\it\dorecurse{100}{a b c } \item \switchtobodyfont[face2]\it\dorecurse{100}{a b c } \item \switchtobodyfont[face3]\it\dorecurse{100}{a b c } \stopitemize \stoptext Could someone explain: 1. What does "effect" mean? Why does "effect={}" embolden the fonts even though nothing ({}) is given as arguments? 2. Similarly, what does "width" do? Why does "width=1.0" shrink the width of the line instead of doing nothing? Thanks in advance. Best, Sylvain

\switchtobodyfont behaves differenctly with splitted parameters
by Sylvain Hubert 08 Nov '20

08 Nov '20

Dear List, after hours of debugging, I finally found out that \switchtobodyfont[face, 20pt] does NOT behave the same with \switchtobodyfont[face]\switchtobodyfont[20pt]. In my case the latter is the correct one, while the former does nothing but falling back to latinmodern. Does anyone know when or why \switchtobodyfont behaves differently with splitted and joined parameters? Thanks. Best, Sylvain

Dear List, The first paragraph of the following example is not indented. \setupindenting[yes,first,4cm] \starttext \section{a} \dorecurse{84}{abc } \dorecurse{84}{abc } \stoptext Does anyone know how to actually get the first paragraph indented? Thanks! Best, Sylvain

ConTeXt Linux installation issues (due to GLIBC dependency)
by Ramkumar KB 08 Nov '20

08 Nov '20

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 *Patchelf Utility* Used the patchelf utility - https://anaconda.org/conda-forge/patchelf *Changed the following Context install files* *install.sh (just before running mtxrun)* *===* patchelf --set-interpreter /my-own-dir/opt/glibc-2.23/lib/ld-linux-x86-64.so.2 --set-rpath /my-own-dir/opt/glibc-2.23/lib:/usr/lib64 $PWD/bin/mtxrun $PWD/bin/mtxrun --script ./bin/mtx-install.lua --update --server="$LMTXSERVER" --instance="$LMTXINSTANCE" --platform="$PLATFORM" --erase --extras="$LMTXEXTRAS" *mtx-install.lua (just before running mtxrunbin)* ==== run("patchelf --set-interpreter /my-own-dir/opt/glibc-2.23/lib/ld-linux-x86-64.so.2 --set-rpath /my-own-dir/opt/glibc-2.23/lib:/usr/lib64 %s", mtxrunbin) run("%s --generate",mtxrunbin) *Error that I see (in the step `make luametatex format`) - * resolvers | formats | changing to format path '/my-own-dir /ConTeXt/tex/texmf-cache/luatex-cache/context/5fe67e0bfe781ce0dde776fb1556f3 2e/formats/luametatex' resolvers | formats | executing runner 'make luametatex format': / my-own-dir/ConTeXt/tex/texmf-linux-64/bin/luametatex --ini --lua=/my-own-dir/chantool/ConTeXt/tex/texmf-context/tex/context/base/mkiv/luat-cod.lmt /my-own-dir/ConTeXt/tex/texmf-context/tex/context/base/mkiv/cont-en. mkxl This is LuaMetaTeX, Version 2.08.01 2097153(/my-own-dir/ConTeXt/tex/texmf-context/tex/context/base/mkiv/cont-en.mkxl(context.mkxl(syst-ini.m kxl !

\define in conflict with \startxtable[]
by Sylvain Hubert 08 Nov '20

08 Nov '20

Dear List, Could anyone manage to typeset the following example? Here [] causes an error "Extra }, or forgotten \endgroup". \starttext \define\sample{ \startxtable[] \startxtablehead \startxrow \startxcell 123\stopxcell \stopxrow \stopxtablehead \stopxtable } \sample \stoptext Thanks in advance.

\section with userdata
by Sylvain Hubert 07 Nov '20

07 Nov '20

Dear List, it is known that we can supply additional userdata like authors to \startsection: \startsection[title=Title][author=Someone] so that the author can be included in the table of contents using \structurelistuservariable{author}. Now I would like to do the same with \section, but according to the wiki <https://wiki.contextgarden.net/Command/_section>, \section doesn't seem to accept any additional parameters like \startsection does. Does anyone know whether there is a workaround to let \section accept userdata parameters? Thanks! Best, Sylvain
