[New-bugs-announce] [issue13631] readline fails to parse some forms of .editrc under editline (libedit) emulation on Mac OS X

[Zvezdan Petkovic]

New submission from Zvezdan Petkovic <zvezdan at zope.com>:

Problem
=======

The changes in r87356 for py3k and r87358 for python-2.7 described in issue 9907 have broken parsing of the initialization file .editrc under editline emulation of readline on Mac OS X.

Background
==========

Both readline and editline allow settings customized per program.
For example, .inputrc file for readline::

    $if Python
        set editing-mode vi
    $endif

will be applied only to Python processes.

Similarly, .editrc file for editline::

    python:bind -v
    python:bind ^I rl_complete

will be applied only to Python processes on Mac OS X.

This works fine on python-2.6.

It's broken on 2.7 and 3.2 and later because the change in issue 9907 moved the rl_initialize() call towards the beginning of the setup function.

Solution
========

The rl_readline_name variable must be set to "python" **before** the call to rl_initialize().  Attached are patches for 2.7 and 3.2.
