Hi again,
Lua has no function to check if a file exists.
ATM I’m using this:
function userdata.file_exists(name)
local f=io.open(name,"r")
if f~=nil then io.close(f) return true
else return false end
end
Is there anything (better) in ConTeXt?
to grep or not to grep ...
io.exists(filename)
lfs.isfile(filename)
and some more, depending on needs
Thank you! I still didn’t earn my yellow belt in grep-fu.
