Hi ConTeXist... How can I find out what version of Lua uses ConTeXt TeXlive 2014 respectively what version of Lua uses Standalone ConTeXt? The point is that Pablo Rodriguez use Fedora 20, which comes with Lua-5.2.2. Pablo tested last version of my module ScanCSV and his current version of standalone ConTeXt gained mistake, while I compiled (with the same current version of Standalone under Win7) the same source code without error .... Error message from log file is: t-scancsv-2015-02-19.lua:81: assertion failed! stack traceback: [C]: in function 'assert' t-scancsv-2015-02-19.lua:81: in function 'ParseCSVLine' t-scancsv-2015-02-19.lua:123: in function 'parsecsvdata' t-scancsv-2015-02-19.lua:180: in function 'opencsvfile' [\directlua]:1: in main chunk Thanx Jaroslav Hajtmar
