vim-airline
|
||||
===========
|
||||
# vim-airline
|
||||
|
||||
lean & mean statusline for vim
|
||||
|
||||
# rationale
|
||||
|
||||
there's already [powerline](https://github.com/Lokaltog/powerline), why yet another statusline?
|
||||
|
||||
* it's standard vimscript, no python needed
|
||||
* it's small. i want the entire plugin to be less than 200 lines as a rule
|
||||
* gets you 90% of the way there: in addition to all the standard goodies, supports [fugitve](https://github.com/tpope/vim-fugitive) and [syntastic](https://github.com/scrooloose/syntastic)
|
||||
* it's fast. since it's so small, it only takes 0.6ms to load. by requiring python, powerline needs 60ms on the same machine.
|
||||
|
||||
# why's it called airline?
|
||||
|
||||
i wrote this on an airplane, and since it's light as air it turned out to be a good name :-)
|
||||
|
||||
# configuration
|
||||
|
||||
there are a couple configuration values available:
|
||||
|
||||
* `g:airline_left_sep` the seperator used on the left side
|
||||
* `g:airline_right_sep` the seperator used on the right side
|
||||
* `g:airline_enable_fugitive` enable/disable fugitive integration
|
||||
* `g:airline_enable_syntastic` enable/disable syntastic integration
|
||||
