10.4: Add readline support to Tiger's python UNIX
For licensing reasons, Python on OS X comes without readline support (libreadline is GPL). Unfortunatley, this earlier hint no longer works in Tiger.

There is, however, a standalone readline distutils package made by Bill Bumgarner. I have slightly adapted it [click to download] to work either with a pre-installed readline from Fink, or with the included readline-5.1 without installing it. Hope this helps!

10.4: Add readline support to Tiger's python

You always can use rlwrap:
Usage: rlwrap [options] command ...

   -a, --always-readline[=password:] 
   -b, --break-chars 
   -c, --complete-filenames
   -C, --command-name 
   -f, --file 
   -h, --help
   -l, --logfile 
   -n, --no-warnings
   -r, --remember
   -v, --version
   -s, --histsize 

bug reports, suggestions, updates:
with any line interpreter.
% port info rlwrap
rlwrap 0.24, sysutils/rlwrap

rlwrap is a 'readline wrapper' that uses the GNU readline library to allow the editing of keyboard input for any other command.

Library Dependencies: readline
Platforms: darwin
: I have defined:
alias irb 'rlwrap irb'
and many similar others, so I can easily edit Ruby code, for example:
% irb
irb(main):001:0> 5.times { p "Hola" }
=> 5

Why not just install Python using Fink? It solves the same problem, but it's much easier than compiling readline from source, and you get easy uninstallation, too.

Hint does not say to compile anything!

If you read the Hint (and the web site) you'll see that you don't have to compile anything! You just have to install the Dev Tools (which *have* readline), and then tell python to use it (by running a tiny script).

This depends on your definition of "easier". I find it easier to add a feature to a working install rather than installing the entire large package from scratch from a different source. Python is provided as a Fink package mainly for internal Fink dependencies so that Fink is independant from MacPython.

There are however two reasons (for me) to prefer MacPython (shipped with OSX) to the Fink python (the same applies to Tcl/Tk):

1) As a developer I have the same environment as an end user on a bare bones OSX so that I can be sure that my software will run also on a daisy OSX box.

2) The GUI libraries are Carbon versions rather than X11 versions as in Fink.
