Hi all, during last several months I came accross three non-critical problems worth reporting here: 1. Empty lines at the beginning of the main file generates an error: -----------------------------ERR This is LuaTeX, Version 1.13.0 (TeX Live 2021) system commands enabled. ** --------------------------------- and compilation crashes. Detected at TL 2021, at two or three month old garden installation is does not appear (maybe it has been fixed yet). ------------------------------MWE \starttext xxx \stoptext --------------------------------- 2. When an error during compilation of "xxx.tex" appears, the file "xxx-error.log" is generated. But sometimes happens that file "-error.log" is created. It makes troubles for Linux command line processing -- if user writes some mask later, "-error.log" string is interpreted by default as list of options of a particular command. It would be very useful if a test preventing an "empty" filename will be added. -----------------------------LOG (file -error.log) return { ["filename"]="", ["lastcontext"]="\n<*> c\n ont-yes.mkiv --c:currentrun=1 --c:fulljobname=./pokus-1.tex --c:input=./pokus-1.tex --c:kindofrun=3 -- --c:maxnofruns=1 --c:once -- -- --c:texmfbinpath=/usr/local/texlive/2021/bin/x86_64-linux", ["lastluaerror"]="?", ["lasttexerror"]="! Interruption", ["linenumber"]=0, ["offset"]=10, } -------------------------------- 3. When simpleslides module is used, interactive element BottomSquares does not change if the file is compiled by ConTeXt from TL2021 whereas with ConTeXt from TL2019 it works. -----------------------------MWE \usemodule[simpleslides][style=BottomSquares,font=Schoolbook,size=20dd,] \starttext \setupTitle[title=Title] \placeTitle \SlideTitle{A+B} blabla \SlideTitle{CCC} blabla \SlideTitle{D+E} blabla \stoptext -------------------------------- Examples attached. The best, Tomáš
