Subject: [clpython-devel] Problem with Python 'open'
Message-ID: <BANLkTikyO6dd1_aEmszuMVadbwk_6VcDug@mail.gmail.com>

Hi --

I have CLPython running on a small example with no I/O, but
when I try opening a file I get:

> Error: Incorrect keyword arguments in (NIL "r") .
> While executing: OPEN, in process listener(1).
> Type :POP to abort, :R for a list of available restarts.
> Type :? for other options.

for

    open(f,'r')

or similar error:

> Error: Incorrect keyword arguments in (NIL NIL) .
> While executing: OPEN, in process listener(1).
> Type :POP to abort, :R for a list of available restarts.
> Type :? for other options.

for

   open(f)

Suggestions please! I'm not much of a Lisp hacker, just trying to get a
Python script to run (much) faster.

Thanks.

There was a typo that resulted in a symbol clash with Lisp's "open" in
implementations other than Allegro's "Modern" mode. If you have
checked out from the git repo, just pull the fix I just committed,
otherwise (e.g. when using Quicklisp) please manually apply this
change:

 https://github.com/franzinc/cl-python/commit/84f0f775bf359ab60ba78e2f58587c316463a6d8

Also, the file handling in CLPython is not well-tested. From a quick
test the basic open, read and close seem to work, but don't be
surprised if other actions fail.

I'm glad you're trying out CLPython. I'm not sure you get the much
faster speed though. Keep us updated.
