HI,
I want to efficiently parse a large collections of files.
The files are in the format :
example title
TITLE
author name
AUTHOR
some lines with summary here
SUMMARY
the real text
TEXT
a list of links
LINKS
I want to use "ByteString" here, but which library should I use to
parse ? "attoparsec" or "bytestringparser",
both export the same interface.
When I use one of these I thaught it would be nice to write something
like this :
fileParser :: Parser Content
fileParser = do
title <- manyTill getInput (string . pack "\nTITLE\n")
author <- manyTill getInput (string. pack "\nTITLE\n")
....
return Content title author ...
But this doesn't work.
Even on a small example :
parseTest (manyTill getInput (string $ pack "SPLIT") (pack "split
the text at SPLIT part two")
I get a stack overflow. Obviously I'm not understanding something here.
Are there any good examples of open source projects which parse
ByteString data ?
thanks in advance,
Pieter
