[Bashdb-pydb] How to add PYTHONPATH for Pydb emacs session

[R. B. <ro...@pa...>]

Works for me. 

Although in pdb, I have found myself writing a wrapper script as you
seem to indicate, with recent versions of pydb, normally you don't
need to. (Well, at least I don't and *I'm* normal.)  pydb tries to install a
symlink in your a binary directory to the python script.

 # ls -l /usr/local/bin/pydb
  lrwxrwxrwx 1 root root 45 2006-09-16 20:37 /usr/local/bin/pydb -> /usr/lib/python2.4/site-packages/pydb/pydb.py


That said, if you want to create a shell script, sure, you still
can. (Or at least I can ;-) Here's what I just tried on a SUSE GNU
linux box as seen above seems to want to put packages in
/usr/lib/python2.4/site-packages:

#!/bin/sh
export PYTHONPATH="/usr/lib/python2.4/site-packages/:$PYTHONPATH:"
/usr/lib/python2.4/site-packages/pydb/pydb.py $*

When I tried running the above script passing a little python program
when I got the pydb prompt. Just to make sure it's what I thought it
should be I ran this:

  (Pydb) import sys
  (Pydb) sys.version
  '2.4.2 (#1, May  2 2006, 08:13:46) \n[GCC 4.1.0 (SUSE Linux)]'
  (Pydb)

I've also installed Python 2.5 and that seems to want to put packages
in /usr/local/lib/python2.5/site-packages instead. So changing this to
the 2.5 location, as a test verified there was nothing magical:

#!/bin/sh
export PYTHONPATH="/usr/local/lib/python2.5/site-packages/:$PYTHONPATH"
/usr/local/lib/python2.5/site-packages/pydb/pydb.py $*

Running the same program stopped as before; upon checking I was indeed
getting something different:

  (Pydb) import sys
  (Pydb) sys.version
  '2.5 (r25:51908, Sep 19 2006, 21:51:15) \n[GCC 4.1.0 (SUSE Linux)]'
  (Pydb) 

To get working from GNU/Emacs. First make sure you can do the
above. :-) Then it is just a matter of entering that location when
prompted. For example, I called the script /tmp/mypdb.sh So when I run
meta-x pydb, and it shows:

  Run pydb (like this): pydb
        
I just change "pydb" to  "/tmp/mpydb.sh /tmp/my-python-script"

The next time I issue M-x pydb though, I get: 

  Run pydb (like this): /tmp/mpydb /tmp/my-python-script

which seems to make sense.
