[Python-Dev] shellwords (original) (raw)

Cool. Based on this thread and an experiment I tried, some obvious (to me) things come to mind:

* gettoken() needs to be fixed to handle the 'bar'asd'foo' case * the shlex class should handle strings as input, not just file-like objects * getword() or getwords() methods in the shlex class could implement the shellwords functionality

Ok, it was easier than I imagined. Here's an example of the new shlex.

Maintaining the old behavior (notice that now strings are accepted as arguments):

import shlex l = shlex.shlex("'foo'a'bar'") l.gettoken() "'foo'" l.gettoken() "a'bar'"

New behavior:

l = shlex.shlex("'foo'a'bar'", posix=1) l.gettoken() 'fooabar'

Introduced iterator interface:

for i in shlex.shlex("'foo'a'bar'"): ... print i ... 'foo' a'bar'

New function, mimicking shellwords:

shlex.splitargs("'foo'a'bar' -o='foo bar'") ['fooabar', '-o=foo bar']

I'm not sure if "posix" and "split_args" are the best names for these features. Suggestions?

I've just commited patch #722686 (and assigned to Guido, as he suggested recently ;-).
