在vimrc和gvimrc中具有相同的“ au FilterWritePost”-在vim中都被调用？

Question

如果我有au FilterWritePost * do_something在.vimrc和au FilterWritePost * do_something2在.gvimrc和开放gVim的，做这个活动，都调用，或是否.gvimrc定义“覆盖” .vimrc里定义（do_something2改为只do_something，或两者）？

Answer 1

Yes they will. You can prevent this from happening by typing it this way

au! FilterWritePost * do_something2

the ! tells the autocommand to replace any other autocommand with the same FilterWritePost signature. If you fire up gvim the .vimrc will fire off first then the .gvimrc so your autocommand in the .vimrc will be replaced with the version in your .gvimrc

Answer 2

In addition to jackerran answer: use autocommand groups:

" Name may be any, but it should not be equal to any of events name. "
" Case is ignored "
augroup ThisDoesSomething
    " Wipe out every event from this group "
    autocmd!
    autocmd! FilterWritePost * do_something
augroup END

This is safe to be put both into vimrc and gvimrc at one time: au! will clear duplicates if they occur.
