runfile

I was sick of adding a bunch of <Leader>r mappings to "run" the various executable or interpretable file types I work in. Why not a single function that auto-magically runs the correct command using some simple rules based on the file name and type?

It should do the Right Thing most of the time and I should be able to easily customize and override in .vimrc.

Installation

Use pathogen.

$ cd .vim/bundle
$ git clone https://github.com/pbrisbin/vim-runfile

Usage

:Run

Default Rules

If file is executable...    Then :Run means...
                            !%

If the filetype matches...  Then :Run means...
cram                        !cram %
cucumber                    !cucumber %
go                          !go run %
haskell                     !runhaskell %
html                        !$BROWSER %
python                      !python %
ruby                        !ruby -Ilib %
sh                          !/bin/sh %
vim                         source %

Extending

If the maps g:runfile_by_name or g:runfile_by_type exist, they are merged into the default rules when the plugin first loads.

Example

let g:runfile_by_name = {
    \ 'config.ru': '!rackup %',
    \ }

let g:runfile_by_type = {
    \ 'markdown': '!markdown2pdf %',
    \ 'html'    : '%!tidy',
    \ }

Notes

1. Right now, the pattern in _by_name is matched against the filename, not the full path. I might change that if it seems limiting.

2. The filename pattern is regex, not glob.

3. The command part of the mapping can be any vim command, it need not execute anything.

4. The rules are tried in key-alphabetical order, not definition order as you might expect or want. This is because of vim, not by design.
