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

for pablo: there are csv scanners built in context

Hans,

I don’t really need this at home, but I’m interested in this.

in addition to the previous mail, t.txt is:

first,second,third,fourth
"1","2","3","4"
"a","b","c","d"
"foo","bar""baz","boogie","xyzzy"

the code is in util-prs.lua (where all kind of parsing code lives)

if you want to use that kind of code outside context you can do something like this:

lua mtxlibs.lua --selfmerge foo.lua

and then in your script load foo.lua

this makes it possible to use the same set of helpers in context as well outside it (alternatively you can just use luatex as lua engine and mtxrun as script runner which is what we mostly do); this means that the context distribution provides all kind of means to set up workflows

I guess you mean m-database.mkiv. But I don’t have a clue on how to
handle it.

I mean, how to ignore the first line and how to make commands from the
so-called cells (A2, B5...; to use them in document combination) reading
an external file.

Many thanks for your help,

Pablo
