Hi all, recently, in the ConTeXt list someone asked how to install Esperanto. I wanted to advise him, so I tried to do it on my computer and I came across the following problem: According to the wiki documentation (https://wiki.contextgarden.net/Command/setuplanguage), I should use "pattern=file" but neither file with full pathname, nor without works in the testing code below (TL2020). The only one way how to setup it is to use a language code. Did I anything wrong, or is it only misdocumented on wiki? Or a feature not implemented yet? Best wishes, Tomáš \starttext\hsize1dd \installlanguage[eo][space=packed,state=start] %\setuplanguage[eo][patterns=/usr/local/texlive/2020/texmf-dist/tex/context/patterns/mkiv/lang-cs.lua] % NO %\setuplanguage[eo][patterns=lang-cs.lua] % NO %\setuplanguage[eo][patterns=lang-cs] % NO \setuplanguage[eo][patterns=cs] % YES \mainlanguage[eo] \input capek-cz \stoptext
