I have a project which needs to use python 2.5, which Leo doesn't run
on anymore. The method I use to keep using Leo with this project is to
create a button which opens a shell with the correct python
environment. It's not as quick or smooth as [Ctrl]-[B] to use Leo's
active interpreter, but it helps.
1. create a node "@button pyshell here" in the foobar-project.leo.
Body contents for that node:
-----
@
Open a windows cmd.exe prompt in the path of the currently selected node.
A mapped drive letter will be created for a UNC path.

@c
d = c.scanAllDirectives(p)
# g.es(g.dictToString(d)) #uncomment to show results of above in log pane
#path = d.get('path')
path = c.getNodePath(p)
name = p.anyAtFileNodeName()
if name:
name = g.os_path_finalize_join(path,name)
g.es(name)
from subprocess import Popen
#Popen(r'cmd.exe /k pushd %s' % path)
Popen(r'%s/pyshell.bat' % path)

2. Create pyshell.bat in my foobar-project directory:
-----
@echo off
echo.
echo. Setting environment for python
echo.
set PYTHONHOME=C:\Python25
set
PYTHONPATH=%PYTHONHOME%;%PYTHONHOME%\Lib;%PYTHONHOME%\DLLs;C:\ESRI\ArcGIS\Bin
set PATH=%PYTHONHOME%;%path%
set py
python --version
echo.
:: add directory of the pyshell script to PATH
pushd %~dp0
set path=%path%;%~dp0
cmd /k
