I have a plugin (FindFile.vim) that needs to run :FindFileCache . whenever I start vim to gather a file cache for quick opening.. I have to run this every time I start vim though.
How might I write a command that runs once, every time that vim starts up?
To get even later than other answers but still just after startup, use a timer in .vimrc. For example, this code in .vimrc waits half a second after startup before setting a variable.
function DelayedSetVariables(timer)
let g:ycm_filetype_blacklist['ignored'] = 1
endfunction
let timer=timer_start(500,'DelayedSetVariables')
(The variable in the example is the blacklist from YouCompleteMe plugin. I assume, the plugin starts up some other process asynchronously which then creates variables, but is not quite ready by the time vim has started. The variable does not exist when I try to set it in .vimrc, an after file, or VimEnter event. This is specific to my Windows system somehow, YCM documentation says .vimrc should work for setting options.)
