Hi. I want to write a haskellquickfind app to get a list of files using human readable hash values (eg the first character of directory/filenames) Eg hquickfind vtl should print /var/tmp/local My implementation should look like this: Every folder/file is token and I want to run a parser. to consume /var Then I want to run it with all subdirs in var where it should fail on anything but t.* ... My Problem : I can't access runP directly to feed the parser with one token and get the result (failure, need more tokens).. Have I missed a function or isn't parsec meant to be used this way? Would you recommend writing your own small parser for this? Another question: Can you use another SourcePos state than SourcePos? Marc
