Hi, I discovered the manuals in the context distribution. My general way to built the manuals were these steps: ``` # execute one time git clone https://github.com/contextgarden/context.git cd context/doc/context/sources/general/manuals/ # for every manual cd $MANUALFOLDER context $MAIN_MANUAL_FILE.tex ``` Is there a way to speed this up, so to build all manuals with one command (some make file or shell script for example)? I saw some problems within the manuals: - In units/units-mkiv.tex the spacing seems not to work with current LMTX. See the attached screenshot (units-mkiv.png) for my rendering. In my understanding the spaces should differ. - I changed some typos(?) and other stuff in that file. The patch is attached (0001-units-mkiv-improve.patch). - math/math-mkiv.tex seems not to compile.

This is normally done by loading special math fonts into the math family slots. Your font set is lacking at least the parameter mentioned earlier. mtx-context | fatal error: return code: 1 - I tried to find a prebuild version and found https://mirror.contextgarden.net/general/manuals/math-mkiv.pdf. However, this document seems to be from 2021 and has a kind of wobbly rendering in Okular/Poppler (I remember the same phenomena with early LMTX). See the screenshot attached (math-mkiv-online.png). Is there a newer version somewhere? Maybe it is meaningful to delete the old version. Best Gerion
