[Pythonmac-SIG] Re: Readline on the Mac

[Andrew Straw]

I've gotten readline to work doing this:

1) Use the setup.py listed below (slightly modified from one Bill 
Bumgartner posted several months ago)
2) Download and un-tgz the GNU readline package in /path/to/readline
3) Get the python source code for your current version of python in 
/path/to/python

4) follow the following commands:

mkdir my_python_readline_module_src
cd my_python_readline_module_src
# copy the setup.py (listed below) into this directory
# point ./readline/readline.h to the readline.h you just downloaded
ln -s /path/to/readline readline
# point ./readline.c to the readline.c from the Python source
ln -s /path/to/python/Modules/readline.c readline.c
sudo python setup.py install

========== setup.py ================
#!/usr/bin/env python

from distutils.core import setup, Extension
import os
import sys

if not (sys.platform == 'darwin') or \
        not 
os.path.exists('/System/Library/PrivateFrameworks/readline.framework'):
     print "no point running this on a system other than OS X w/dev 
tools."
     sys.exit(1)

setup (name = "readline",
        description = "readline package for OS X python",
        author = "readline.c came straight from Python source",
        author_email = "bbum@codefab.com",
        url = "http://www.python.org",
        ext_modules = [ Extension("readline",
                                  ["readline.c"],
                                  include_dirs=['.'],
                                  extra_compile_args=[
     "-g",
     "-O0",
     "-DMACOSX",
     ],
                                  extra_link_args=[
     '-g',
     '-F/System/Library/PrivateFrameworks/',
     '-framework',
     'readline'
     ])
                        ]
        )

======== end of setup.py =============

PS My version of /System/Library/PrivateFrameworks/readline.framework/ 
doesn't have the Headers directory, which is why you have to download 
the GNU headers.

PPS How does Apple deal with the GPL-ness of readline?  I don't see any 
mention of GNU or the GPL in the PrivateFrameworks version.  Maybe 
they've got a private, non-GNU, readline-compatible library?  If so, 
why don't they make their own headers? (Maybe because it would be 
difficult/impossible to make a readline header without violating the 
copyright?)
