The second is more universal, but it only works in ConTeXt MKIV.

You probably mean something ...
UserCSVSeparator = ';'
UserCSVLeftDelimiter = ''
UserCSVRightDelimiter = ''
function ParseCSVdata(string2parse, separator, leftdelimiter,
rightdelimiter)
leftdelimiter = leftdelimiter or Ld or UserCSVLeftDelimiter or ""
rightdelimiter = rightdelimiter or Rd or UserCSVRightDelimiter or ""
if leftdelimiter ~= '' and rightdelimiter ~= '' then
local result = { }
local pattern = string.esc(leftdelimiter) .. "(.-)" ..
string.esc(rightdelimiter)
for s in string.gmatch(string2parse,pattern) do
table.insert(result,s)
end
return result
else
return string.split(string2parse,separator or Sep or
UserCSVSeparator or ";")
end
end
but anyhow, this might (name) clash at some point i guess, for instance
because of using globals like Ld
In order to be more or less compatible with the context module and third
party code setup, in context you need to do:
thirddata = thirddata or { }
thirddata.cvs = {
separator = ';',
leftdelimiter = '',
rightdelimiter = '',
}
function
thirddata.cvs.parse(string2parse,separator,leftdelimiter,rightdelimiter)
leftdelimiter = leftdelimiter or thirddata.leftdelimiter or ""
rightdelimiter = rightdelimiter or thirddata.rightdelimiter or ""
if leftdelimiter ~= "" and rightdelimiter ~= "" then
local result = { }
local pattern = string.esc(leftdelimiter) .. "(.-)" ..
string.esc(rightdelimiter)
for s in string.gmatch(string2parse,pattern) do
table.insert(result,s)
end
return result
else
return string.split(string2parse,separator or
thirddata.separator or ";")
end
end
-- print(table.serialize(thirddata.cvs.parse("11,ss,cc",",")))
-- print(table.serialize(thirddata.cvs.parse("[11] [ss] [cc]","","[","]")))
but i have no clue how this is used so there might be better approaches
