Your Development Environment
|
|
============================
|
|
|
|
Testing your code is very important.
|
|
|
|
|
|
|
|
Text Editors
|
|
::::::::::::
|
|
|
|
|
|
VIM
|
|
---
|
|
|
|
|
|
There exist a couple of plugins and settings for the VIM editor to aid python
|
|
development. If you only develop in Python, a good start is to set the default
|
|
settings for indentation and linewrapping to values compliant with PEP8::
|
|
|
|
set textwidth=79
|
|
set shiftwidth=4
|
|
set tabstop=4
|
|
set expandtab
|
|
set softtabstop=4
|
|
set shiftround
|
|
|
|
With these settings newlines are inserted after 79 characters and indentation
|
|
is set to 4 spaces per tab. If you also use VIM for other languages, there is a
|
|
handy plugin at indent_, which handles indentation settings for python source
|
|
files.
|
|
Additionally there is also a handy syntax plugin at syntax_ featuring some
|
|
improvements over the syntax file included in VIM 6.1.
|
|
|
|
These plugins supply you with a basic environment for developing in Python.
|
|
However in order to improve the programming flow we also want to continually
|
|
check for PEP8 compliance and check syntax. Luckily there exist PEP8_ and
|
|
Pyflakes_ to do this for you. If your VIM is compiled with `+python` you can
|
|
also utilize some very handy plugins to do these checks from within the editor.
|
|
For PEP8 checking install vim-pep8_. Now you can map the vim function
|
|
`Pep8()` to any hotkey or action you want. Similarly for pyflakes you can
|
|
install vim-pyflakes_. Now you can map `Pyflakes()` like the PEP8 function and
|
|
have it called quickly. Both plugins will display errors in a quickfix list and
|
|
provide an easy way to jump to the corresponding line. A very handy setting is
|
|
calling these functions whenever a buffer is saved. In order to do this, enter
|
|
the following lines into your vimrc::
|
|
|
|
autocmd BufWritePost *.py call Pyflakes()
|
|
autocmd BufWritePost *.py call Pep8()
