PythonTidy

[Chuck Rhode]

I couldn't find a routine to clean up, regularize, and reformat Python
code, so I wrote one:

http://www.lacusveris.com/PythonTidy/PythonTidy.python

Now, I'm looking for beta-testers. Compensation is a bit on the low
side. In fact it's limited to the satisfaction of helping out.
Thanks.

$ cat test.py
#!/usr/bin/env python2.5
# vim: set fileencoding=utf-8 :

for i in xrange ( 3) :
print i

$ python2.5 PythonTidy.python < test.py
#!/usr/bin/python
# -*- coding: utf-8 -*-

for i in xrange(3):
print i

About changing the shebang line: I'll take it as a bug.
About changing the encoding declaration from vim-style to emacs-style:
I'll take it as an insult :)

Both are comments, and should be left that way. Besides, there is no
officially preferred way for each of them. BTW, in a recent thread on
this newsgroup, most people said they preferred #!/usr/bin/env python over
#!/usb/bin/python for the shebang line. See http://tinyurl.com/yngmfr .

Best regards.

This is not "emacs-style", this is Python normalized source encoding
directive for correct interpretation of u"..." strings by Python
interpreter.

See http://www.python.org/dev/peps/pep-0263/

directive for correct interpretation of u"..." strings by Python
interpreter.

See http://www.python.org/dev/peps/pep-0263/

The -*- syntax is emacs-style. The encoding directive is anything that
matches r"coding[=:]\s*([-\w.]+)". The docs recommend to use either
emacs-style or vim-style. See http://docs.python.org/ref/encodings.html

This is not "emacs-style", this is Python normalized source encoding
directive for correct interpretation of u"..." strings by Python
interpreter.

So is "# vim: set fileencoding=utf-8". Anything matching
"coding[:=]\s*([-\w.]+)" on the first or second line counts.

See http://www.python.org/dev/peps/pep-0263/

Yes, you should. 8-)

See http://www.python.org/dev/peps/pep-0263/

Where does it say it has to be emacs-style? It just uses that style as
example as far as I can see. The real definition is a regexp:

coding[:=]\s*([-\w.]+)

So the vim-style is fine. No need to replace it.

Aye, sorry for my missreading...

Ooh! <wounded>

Both are comments, and should be left that way. Besides, there is no

Thanks for the link. I was unaware of the /usr/bin/env technique and
the controversy surrounding it.

Thanks, too, for trying *PythonTidy*.

As you have no doubt perceived, *PythonTidy* is *not* "table driven."
It is a script after all. I decided before writing it that I didn't
really need to externalize all the options; nevertheless, most are
declared near the beginning where they sit just begging for end-user
involvement. See: CODING_SPEC and SHEBANG. *PythonTidy* is all about
consistency, consistency, and consistency. You can use it to
standardize shebangs and coding across a whole library of Python
scripts.

No, thanks you for writing such a tool!

The fact that I immediately noticed them and came up with an example to
raise both issues is a indicator of how easy it would be to customize the
script :)
