Hello all, I wonder if the handling of wildcard arguments by LuaTeX running as texlua is documented anywhere, and if it's controllable.
With LuaTeX, irrespective of platform, arguments are passed 'as is' to Lua, so if we have a test.tex file \directlua{for _,v in ipairs(arg) do print(v) end} \end and run luatex test.tex '*' -- macOS/Linux luatex test.tex * -- Windows we print "*". On the other hand, if we have test.lua file for _,v in ipairs(arg) do print(v) end and try texlua test.lua '*' -- macOS/Linux texlua test.lua * -- Windows we get "*" on macOS/Linux and ... whatever is in the current directory on Windows. If we use '*' there, that's *exactly* what gets shown - no expansion, but also no loss of the ' chars (of course we can clean up). I *think* that the only expansion is the same as e.g. dir would do - only "*" and "?", and if there are no matches things are passed on as-is. I can't see that this behaviour is documented anywhere, nor if it's at all controllable. Does anyone have any insight? Joseph
