Hi Hans.
One more I ask You about this thing. When I have other separator - for
example ";" then c.txt data file is:
first,second,third,fourth
"1";"2";"3";"4"
"a";"b";"c";"d"
"foo";"bar""baz";"boogie";"xyzzy"
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:
\starttext
\startluacode
local mycsvsplitter = utilities.parsers.rfc4180splitter()
utilities.parsers.rfc4180splitter.separator=";"
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])
context.NC()
context.NR()
end
context.stoptabulate()
\stopluacode
\stoptext
