 1" vimrc file for following the coding standards specified in PEP 7 & 8.
 2"
 3" To use this file, source it in your own personal .vimrc file (``source
 4" <filename>``) or, if you don't have a .vimrc file, you can just symlink to it
 5" (``ln -s <this file> ~/.vimrc``).  All options are protected by autocmds
 6" (read below for an explanation of the command) so blind sourcing of this file
 7" is safe and will not affect your settings for non-Python or non-C files.
 8"
 9"
10" All setting are protected by 'au' ('autocmd') statements.  Only files ending
11" in .py or .pyw will trigger the Python settings while files ending in *.c or
12" *.h will trigger the C settings.  This makes the file "safe" in terms of only
13" adjusting settings for Python and C files.
14"
15" Only basic settings needed to enforce the style guidelines are set.
16" Some suggested options are listed but commented out at the end of this file.
17
18
19" Number of spaces to use for an indent.
20" This will affect Ctrl-T and 'autoindent'.
21" Python: 4 spaces
22" C: 8 spaces (pre-existing files) or 4 spaces (new files)
23au BufRead,BufNewFile *.py,*pyw set shiftwidth=4
24au BufRead *.c,*.h set shiftwidth=8
25au BufNewFile *.c,*.h set shiftwidth=4
26
27" Number of spaces that a pre-existing tab is equal to.
28" For the amount of space used for a new tab use shiftwidth.
29" Python: 8
30" C: 8
31au BufRead,BufNewFile *py,*pyw,*.c,*.h set tabstop=8
32
33" Replace tabs with the equivalent number of spaces.
34" Also have an autocmd for Makefiles since they require hard tabs.
35" Python: yes
36" C: no
37" Makefile: no
38au BufRead,BufNewFile *.py,*.pyw set expandtab
39au BufRead,BufNewFile *.c,*.h set noexpandtab
40au BufRead,BufNewFile Makefile* set noexpandtab
41
42" Use the below highlight group when displaying bad whitespace is desired
43highlight BadWhitespace ctermbg=red guibg=red
44
45" Display tabs at the beginning of a line in Python mode as bad.
46au BufRead,BufNewFile *.py,*.pyw match BadWhitespace /^\t\+/
47" Make trailing whitespace be flagged as bad.
48au BufRead,BufNewFile *.py,*.pyw,*.c,*.h match BadWhitespace /\s\+$/
49
50" Wrap text after a certain number of characters
51" Python: 79 
52" C: 79
53au BufRead,BufNewFile *.py,*.pyw,*.c,*.h set textwidth=79
54
55" Turn off settings in 'formatoptions' relating to comment formatting.
56" - c : do not automatically insert the comment leader when wrapping based on
57"    'textwidth'
58" - o : do not insert the comment leader when using 'o' or 'O' from command mode
59" - r : do not insert the comment leader when hitting <Enter> in insert mode
60" Python: not needed
61" C: prevents insertion of '*' at the beginning of every line in a comment
62au BufRead,BufNewFile *.c,*.h set formatoptions-=c formatoptions-=o formatoptions-=r
63
64" Use UNIX (\n) line endings.
65" Only used for new files so as to not force existing files to change their
66" line endings.
67" Python: yes
68" C: yes
69au BufNewFile *.py,*.pyw,*.c,*.h set fileformat=unix
70
71
72" ----------------------------------------------------------------------------
73" The following section contains suggested settings.  While in no way required
74" to meet coding standards, they are helpful.
75
76" Set the default file encoding to UTF-8: ``set encoding=utf-8``
77
78" Puts a marker at the beginning of the file to differentiate between UTF and
79" UCS encoding (WARNING: can trick shells into thinking a text file is actually
80" a binary file when executing the text file): ``set bomb``
81
82" For full syntax highlighting:
83"``let python_highlight_all=1``
84"``syntax on``
85
86" Automatically indent based on file type: ``filetype indent on``
87" Keep indentation level from previous line: ``set autoindent``
88
89" Folding based on indentation: ``set foldmethod=indent``
