+" vimrc file for following the coding standards specified in PEP 7 & 8.
+" To use this file, source it in your own personal .vimrc file (``source
+" <filename>``) or, if you don't have a .vimrc file, you can just symlink to it
+" (``ln -s <this file> ~/.vimrc``). All options are protected by autocmds
+" (read below for an explanation of the command) so blind sourcing of this file
+" is safe and will not affect your settings for non-Python or non-C files.
+" All setting are protected by 'au' ('autocmd') statements. Only files ending
+" in .py or .pyw will trigger the Python settings while files ending in *.c or
+" *.h will trigger the C settings. This makes the file "safe" in terms of only
+" adjusting settings for Python and C files.
+" Only basic settings needed to enforce the style guidelines are set.
+" Some suggested options are listed but commented out at the end of this file.
+" Number of spaces that a pre-existing tab is equal to.
+" For the amount of space used for a new tab use shiftwidth.
+au BufRead,BufNewFile *py,*pyw,*.c,*.h set tabstop=8
+" What to use for an indent.
+" This will affect Ctrl-T and 'autoindent'.
+" Python: 4 spaces
+" C: tabs (pre-existing files) or 4 spaces (new files)
+au BufRead,BufNewFile *.py,*pyw set shiftwidth=4
+au BufRead,BufNewFile *.py,*.pyw set expandtab
+fu Select_c_style()

+au BufRead,BufNewFile *.c,*.h call Select_c_style()
+au BufRead,BufNewFile Makefile* set noexpandtab
+" Use the below highlight group when displaying bad whitespace is desired.
+highlight BadWhitespace ctermbg=red guibg=red
+" Display tabs at the beginning of a line in Python mode as bad.
+au BufRead,BufNewFile *.py,*.pyw match BadWhitespace /^\t\+/
+" Make trailing whitespace be flagged as bad.
+au BufRead,BufNewFile *.py,*.pyw,*.c,*.h match BadWhitespace /\s\+$/
+" Wrap text after a certain number of characters
+" Python: 79
+" C: 79
+au BufRead,BufNewFile *.py,*.pyw,*.c,*.h set textwidth=79
+" Turn off settings in 'formatoptions' relating to comment formatting.
+" - c : do not automatically insert the comment leader when wrapping based on
+" 'textwidth'
+" - o : do not insert the comment leader when using 'o' or 'O' from command mode
+" - r : do not insert the comment leader when hitting <Enter> in insert mode
+" Python: not needed
+" C: prevents insertion of '*' at the beginning of every line in a comment
+au BufRead,BufNewFile *.c,*.h set formatoptions-=c formatoptions-=o formatoptions-=r
+" Use UNIX (\n) line endings.
+" Only used for new files so as to not force existing files to change their
+" line endings.
+" Python: yes
+" C: yes
+au BufNewFile *.py,*.pyw,*.c,*.h set fileformat=unix
+" ----------------------------------------------------------------------------
+" The following section contains suggested settings. While in no way required
+" to meet coding standards, they are helpful.
+" Set the default file encoding to UTF-8: ``set encoding=utf-8``
+" Puts a marker at the beginning of the file to differentiate between UTF and
+" UCS encoding (WARNING: can trick shells into thinking a text file is actually
+" a binary file when executing the text file): ``set bomb``
+" For full syntax highlighting:
+"``let python_highlight_all=1``
+"``syntax on``
+" Automatically indent based on file type: ``filetype indent on``
+" Keep indentation level from previous line: ``set autoindent``
+" Folding based on indentation: ``set foldmethod=indent``
