How to use ctags to autocomplete in vim

Question

I am trying to develop an Android project in vim.But to find it a little boring to search in ctags for one method. Is there a way to show autocomplete list in vim using ctags?

Answer 1

I want to clarify: it seems that you already have ctags installed and would like to know how to use it to autocomplete method names, right?

As romainl mentions, <Cn> and <Cp> are what you are looking for. They are complete using next match and complete using previous match , respectively.

However, they are not the only vim autocomplete types; see :he ins-completion for the rest (including spelling and file names). One specific completion that I would like to point out is <Cx><Co> (omni-completion), which you may find useful.

If you weren’t just doing autocompletion: in this similar SO question, the accepted answer of richq contains some useful information about ctags in general.

Answer 2

I did not try autocomplete in VIM, but a quick search was found http://vim.wikia.com/wiki/Any_word_completion : the option "complete" controls the search for keywords (including files, tag files , buffers, etc.).

Answer 3

You can complete everything with [TAB], with this in vimrc. We use [char] [char] [dot] [tab] to trigger tag completion. Also see fooobar.com/questions/392284 / ... for how to integrate spelling, thesaurus, and vocabulary.

  :inoremap <Tab> <CR>=MoshTabOrComplete()<CR> function! MoshTabOrComplete() if col('.') > 3 \ && strpart( getline('.'), col('.')-3, 4 ) =~ '^[a-zA-Z]\+[.]' " prev 2 char are alpha+dot? " Tag-completion eg. print.<tab> will complete to printf or println return "\<BS>\<Cx>\<C-]>" endif " if exists("g:MoshThesaurusOmniCompleter") && col('.') > 3 " \ && strpart( getline('.'), col('.')-3, 4 ) =~ '^[a-zA-Z]\+[!%?~-]' " prev 2 char are alpha+punct? " Calls MoshThesaurusOmniCompleter " Test: qieut!<tab> will spell correct to quiet, more tests in ./thesaurus-omni.vim " return "\<Cx>\<Co>" " endif if col('.') > 1 && strpart( getline('.'), col('.')-2, 3 ) =~ '^\w' " prev char is alphabet? " Usual omni-completion return "\<CN>" endif " Insert regular TAB return "\<Tab>" endfunction
