Strange issue with ctrlp.vim and vim-airline for gvim

[lervag]

Hi,

I suspect this is an issue with vim-airline, see vim-airline issue 156. In case it might be due to issues in both plugins or just in ctrlp.vim, I also open the issue here.

I found a strange issue/inconsistency with vim-airline and ctrlp.vim for gvim, depending on whether ctrlp.vim is loaded or not:

1. If ctrlp.vim is loaded: The welcome info is not shown.
2. If ctrlp.vim is not loaded: The default vim-airline colorscheme( dark) is not activated until I issue the command :AirlineTheme dark.

I have reproduced the issue with a minimal vimrc file:

set nocompatible

set rtp+=~/.vim/bundle/ctrlp.vim
set rtp+=~/.vim/bundle/vim-airline

filetype plugin indent on
syntax enable
set keywordprg=":help"
set autoindent
set backspace=indent,eol,start
set ttimeout
set expandtab
set ttimeoutlen=50
set laststatus=2

Screenshot 1: ctrlp.vim is not loaded.

Screenshot 2: ctrlp.vim is loaded.

The issue was already fixed in recent commits from vim-airline.

Does (or did) airline detect the present of ctrlp? If the ctrlp.vim script wasn't even loaded, then it probably wasn't its fault if something in airline didn't load as a result. Also, the welcome info can be cleared by changes to the statusline.

I think airline has some sort of ctrlp.vim trigger that fired a change of the statusline. But I did not really get the details of what was wrong. In any case, it was not a fault with ctrlp.vim. :)
