Hi all!

I am beginning to use LEPL. It seems very promising but I have two problems.
I guess the answer is easy or already written somewhere, but I searched for
some time now and I did not found yet :(

Firstly, this very simple code:

with TraceVariables():
from lepl import *
PERCENT = Token('%')
TEXT = Token('[^\n]*')
comment = PERCENT & TEXT
print(comment.parse('% ThisIsAComment'))

outputs:

Traceback (most recent call last):
  File
"/Library/Frameworks/Python.framework/Versions/3.2/lib/python3.2/site-packa ges/LEPL-5.0.0-py3.2.egg/lepl/stream/maxdepth.py",
line 55, in _matcher
    (result2, stream2) = yield generator
StopIteration

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
  File "<stdin>", line 6, in <module>
  File
"/Library/Frameworks/Python.framework/Versions/3.2/lib/python3.2/site-packa ges/LEPL-5.0.0-py3.2.egg/lepl/core/config.py",

    raise FullFirstMatchException(stream1)
lepl.stream.maxdepth.FullFirstMatchException: The match failed in <string>
at '% ThisIsAComment' (line 1, character 1).

I do not really see why it does not work... I did some tests with only '%'and it is correctly detected.

The second (and last) point ; this simple code:

test = Token(String())
test.parse('"irt"')

produces:

Traceback (most recent call last):

    'a regular expression: {0}', rewrite))
lepl.lexer.support.LexerError: A Token was specified with a matcher, but the
matcher could not be converted to a regular expression: And(NfaRegexp,
Transform, NfaRegexp)

It is as if the regexp behind String() was not recognized by LELP itself. Do
I miss something?

Thank you very much if you can help me or give me some clues :)
