Hi Hans.
One more I ask You about this thing. When I have other separator - for 
example ";" then c.txt data file is:


I was unable to figure out how to set the separator (and others default 
values too) so as to replace the default value in the library util-prs.lua
Is there anything as utilities.parsers.rfc4180splitter.separator=";"???

This library is loaded automatically? Or as a module?

Thanks Jaroslav Hajtmar

Here is minimal example for Your correction:



local mycsvsplitter = utilities.parsers.rfc4180splitter()

local crap = io.loaddata("c.txt")

local list, names = mycsvsplitter(crap,true)   inspect(list) inspect(names)
local list, names = mycsvsplitter(crap)        inspect(list) inspect(names)

context.starttabulate { "|l|r|" }
for i=1,#list do
     local l = list[i]
     context.NC() context(l[1])
     context.NC() context(l[3])
