Re: [ft-devel] Fwd: Custom search functionality & Python3 compatibility of 'docmaker' (Re: Freetype-devel Digest, Vol 159, Issue 29)

[Hin-Tak Leung]

I wonder why all the python-savy people on the list haven't spoken up yet. 
Python 2 and 3 compatibility is not either or: the python people provide 
compatability modules for that, under the __future__ namespace. Typically you do

from __future__ import <stuff>

To make your python script compatible with both . The __future__ module is 
available in python 2.6 onwards and more extensive in python 2.7, and is no-op 
in python 3.

There are two such examples in ghostscript 's toolbin directory, the pxl*.py 
scripts. (I made those changes a few years ago).

The typical python distribution also ships two scripts, 2to3 and 3to2, to 
automatically migrate scripts or flag compatibility problems between python 2 
and 3. And also, please read the documentation of the 2to3 module...

 I always like a conservative and
 backwards compatible approach.
 However, if you can convince me that we
 *must* use a Python?3 feature
 not available in Python?2 I will
 reconsider...
