Pimp (Python Chimp) is based on (blatantly copied from) the Chimp plugin
(vimscript #2348). It provides a very simple REPL mechanism by allowing you to
evaluate the contents of the active vim buffer in a running python console and
interact with the results.

To use the plugin you have to open a terminal (e.g. xterm) and run one of the
two scripts provided in the 'bin' directory. For a split screen configuration
run ~/.vim/bin/vimPython.bash. For a gvim session interacting with a python
interpreter running in another window run ~/.vim/bin/gvimPython.bash. Note that
you have to *execute* the scripts, not source them.
Now open a python source file or set the filetype to python (:set ft=python).
Enter some python code, then hit <Esc> for normal mode, followed by <Leader>pf.
The contents of the buffer should now be evaluated in the python console.
*Note*
The launching scripts try to run gvim, either in the terminal version (gvim -v,
in the vimPython.bash script) or the gui version (gvimPython.bash). It is
possible to run pimp with the non-gui version of vim by changing vimPython.bash.
However in this case evaluating marked text in visual mode will not work.
=Default bindings=
Assuming that your <Leader> key is '':
\pf Evaluate the current buffer (normal mode)
\pb Evaluate the marked code (visual mode).
=Tips=
- To move between the windows in the split screen configuration hit <Ctrl>-a
<Tab> (<Ctrl>-a is the escape key of gnu screen).
- To resize the window hit <Ctrl>-a followed by :resize N<Enter> where N is the
number of lines, E.g. <Ctrl>-a:resize 10<Enter>.
- To scroll back hit <Ctrl>-a<Esc>. That enters screen's copy mode (similar to
vim's visual mode). To exit that mode hit <Esc>.
- *New* As of Pimp version 0.5, evaluation of code selected in visual mode
actually works! Try using the right-extended visual block mode (Ctrl-v $) to
mark indented code (e.g. inside a function) in order to evaluate it. Take
advantage of the visual block mode to mark the code without the indentation
of course.
- The code is evaluated in IPython's namespace. That makes it possible to
access previously defined variables, functions etc. The reverse is true as
well - it's possible to switch to the IPython window and interact with the
results of the evaluated code, invoke functions etc.
- IPython has an abundance of 'magic' commands. For example it's possible to
'cd', 'pwd' etc. from within IPython. Check the IPython documentation for
details.
It is advised to read the gnu screen manual (man screen) for additional
information about gnu screen's options and capabilities.

| install details |
Pimp depends on IPython (http://ipython.scipy.org) as the python shell and on
gnu screen (http://www.gnu.org/software/screen) for it's operation. It is also
recommended to install the full version of vim (the package is named vim-gnome
under Ubuntu and vim-enhanced in Fedora).
Under Debian/Ubuntu:
sudo apt-get install ipython screen vim-gnome
Under Fedora:
yum install ipython screen vim-enhanced
=Installing the plugin=
mkdir ~/.vim
cd ~/.vim
tar -xvzf /path/to/Pimp.tar.gz
chmod +x ~/.vim/bin/*.bash
Add the following to your ~/.vimrc file:
filetype plugin on
=Keyboard bindings=
You may override the default keyboard bindings in your .vimrc file. For example
to bind Ctrl-e add the following lines to your .vimrc file:
map <c-e> <Plug>PimpEvalFile
imap <c-e> <Esc><Plug>PimpEvalFilea
vmap <c-e> <Plug>PimpEvalBlock
=Problems and solutions=
When working in the split screen configuration, vim is run under a gnu screen
session. gnu screen itself runs inside a terminal emulator, e.g. konsole. Both
gnu screen and the terminal it is run in can cause various problems. Those
problems include trapping of keyboard shortcuts, wrong handling of colors
(relevant to users of CSApprox - vimscript #2390) etc. Please refer to the file
~/.vim/reference/pimp/PimpCaveats.README for details.
=Testing=
This plugin has been tested on Ubuntu 8.10 and Fedora 9. If you can test it on
other platforms I'll be happy to hear about any platform related bugs and
solutions, and will integrate the fix into the next version.
Please send me an email if you have any problem installing or using the plugin.
My email is listed on my profile page.
