#PySmell

PySmell is a python IDE completion helper.

It tries to statically analyze Python source code, without executing it, and generates information about a project's structure that IDE tools can use.

There is currently support for Vim, Emacs and TextMate. Feel free to contribute your own favourite editor bindings, or to improve the existing ones.

##Download and Installation

Run the following commands (without $ preceding) $ git clone git://github.com/rohdef/pysmell.git (Warning! Do not do 'reset --hard' if you modified the original source, it will overwrite those changes!) $ git reset --hard HEAD

• There's two ways to use this, if you want to import it as a part of your own Python project go to the cloned pysmell, and copy the pysmell subdirectory to you project. From there you can use it as seen in runPySmell.py

More parsers and out systems can be found in the outputHandlers directory, and more examples can be found in runPySmell.py

• The second way is if you want pysmell to run as a kind of service for another programming language or independantly in another way. In this case modify runPySmell.py to your needs.

The original PySmell is available at PyPI.

In the source directory do: On Ubuntu and similar *nix systems: $ sudo setup.py install Other *nix systems # python setup.py install

You should be able to import pysmell inside your Python interpreter and invoke pysmell at the command line.

You can track the development of PySmell by visiting GitHub. You can click 'Download' to get it as a zip/tar if you don't have git installed. python setup.py develop will setup your enviroment.

##Usage

These usage instructions is for the original pysmell setup

Before you invoke PySmell, you need to generate a PYSMELLTAGS file:

cd /root/of/project
pysmell .

If you want to specifically include or exclude some files or directories (eg. tests), you can use:

pysmell [Package Package File File ...] [-x Excluded Excluded ...]

Check for more options by invoking pysmell without any arguments

##Using external libraries

PySmell can handle completions of external libraries, like the Standard Library and Django.

To use external libraries, you have to first analyze the libraries you want, eg. for stdlib:

pysmell . -x site-packages test -o ~/PYSMELLTAGS.stdlib

This will create PYSMELLTAGS.stdlib in your HOME. Copy that in the root of your project, and repeat for other libraries by changing the extension. Note that you still have to have a root PYSMELLTAGS file with no extension at the very root of your project.

##Partial tags

Sometimes it's useful to not pollute global namespaces with tags of sub-projects. For example, assume that there is a Tests package, which has hundreds of tests, together with a few testing-related modules. You only want to see these completions when working on test file.

To accomplish that, you can put PYSMELLTAGS.* files inside subdirectories, and they will be used only when you're working on a file somewhere in that directory or its children.*

pysmell Tests/FunctionalTest.py Tests/UndoTestCase.py -o Tests/PYSMELLTAGS.Tests

The information in FunctionalTest and UndoTestCase will only be accessible when editing a file inside the Tests package.

##Vim

To use PySmell omnicompletion from inside Vim, you have to have:

1. Python support in vim (:echo has('python'))
2. The pysmell package in the PYTHONPATH that Vim uses: python import pysmell should work.
3. Drop pysmell.vim in ~/.vim/plugin
4. :setlocal omnifunc=pysmell#Complete Note: If you want to always use pysmell for python, do: autocmd FileType python setlocal omnifunc=pysmell#Complete
5. [OPTIONAL] Select a matcher of your liking - look at pysmell.vim for options. Eg: :let g:pysmell_matcher='camel-case'

You can then use ^X^O to invoke Vim's omnicompletion.

You can generate debugging information by doing:

:let g:pysmell_debug=1
:e PYSMELL_DEBUG

Debug information will be appended in that buffer, copy and paste it into the report.

##TextMate

Double-click PySmell.tmbundle :)

Complete with alt-esc - look into the bundle for more commands.

You can find the bundle in the source distribution - it's not installed with the egg, because it's too much trouble.

Set TM_PYTHON in your Shell Variables to point to the Python where you installed PySmell.

##Emacs

Put pysmell.el into your load-path, and inside your .emacs file put:

(require 'pysmell)
(add-hook 'python-mode-hook (lambda () (pysmell-mode 1)))

Complete with M-/, create tags with M-x pysmell-make-tags

Pymacs is required as well.

#Reporting issues

Please report issues and bugs at https://github.com/rohdef/pysmell/issues I will try to fix them at the best of my abilities. I didn't write this to start with, so I won't promise anything.

If you can create a unit test that exposes that behaviour, it'd be great!

The original PySmell is hosted at Google Code.
