lean & mean statusline for vim that's light as air
2013-06-30 19:29:35 +00:00
# rationale
2013-07-01 23:49:40 +00:00
there's already [powerline][b], 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
2013-07-02 01:33:10 +00:00
* it gets you 90% of the way there; in addition to all the standard goodies, it integrates with [vim-bufferline][f], [fugitive][d], and [syntastic][e]
* it looks good with regular fonts, and provides configuration points so you can use unicode or powerline symbols
2013-07-03 02:51:10 +00:00
* it's fast to load, taking roughly 1ms. by comparison, powerline needs 60ms on the same machine.

2013-07-03 13:40:58 +00:00
what about [old powerline][a]?
* the old version still works well, but since its deprecated new features won't get added

# why's it called airline?
2013-07-03 02:51:10 +00:00
i wrote the initial version on an airplane, and since it's light as air it turned out to be a good name. thanks for flying vim!

# prerequisites
for this plugin to work properly `lazyredraw` needs to be set. during development i had this on the entire time, and it turns out that this has a major impact in colors being able to change prompty (ironic that lazy == eager here). i'm still tracking down the cause and hopefully in the future this requirement can be removed.

1. the powerline font symbols are not showing up
* the older deprecated [vim-powerline][a] uses different codes compared to the newer [powerline][b].
* you can grab prepatched fonts at [powerline-fonts][c], or you can manually set the relevant `g:` variables
2013-07-02 01:33:10 +00:00
2. there is a pause when leaving insert mode
2013-07-02 00:35:16 +00:00
* you need to set `ttimeoutlen` to a low number; 50 is recommended
2013-07-03 15:27:05 +00:00
3. you get the error `Unknown function: fugitive#head`
2013-07-02 15:44:59 +00:00
* you are probably using version 1.2, which is very old...download v2 from the [project page][d].
