Vim Ctrl-]標記跳轉僅適用於命令

Question

我在vimscript上寫了一個插件，想跳到使用標簽的函數定義。 我已經安裝了ctags，配置了vim選項set tags=./tags; 在.vimrc中，並在腳本目錄中使用ctags -R制作了標記文件。 在我的腳本中，我具有以下功能：

func s:OnWipeoutEvent()
" ...
endfunc

和命令：

command! -bar -nargs=* -complete=file -bang TermdebugEasymaps
            \ call s:StartDebug(<bang>0, <f-args>)

當我嘗試使用Ctrl-] vim跳轉到函數（ OnWipeoutEvent() ）時，vim說： E257: ctag: tag not found. 因此它不適用於函數定義，但適用於vim命令定義。 我可以使用Ctrl-]跳轉到命令。 為什么？ 我怎么解決這個問題？

UPD：我認為這種行為是s:OnWipeoutEvent()函數名稱中s:前綴的結果。 因為在vim命令行中輸入tag s:OnWipeoutEvent時可以跳轉到函數定義。 可能是Ctrl-]使用不帶此前綴的函數名稱。 知道如何解決嗎？

UPD2：嘗試使問題更清楚。 下面是我的vim腳本的一部分：

func s:OnWipeoutEvent()
"...
endfunc

augroup termdebug-easymaps
    autocmd BufWipeout * call s:OnWipeoutEvent()
augroup END

command! -bar -nargs=* -complete=file -bang TermdebugEasymaps
            \ call s:StartDebug(<bang>0, <f-args>)

標簽文件：

TermdebugEasymapsCommand    termdebug-easymaps.vim  /^command! -bar -nargs=* -complete=file -bang TermdebugEasymapsCommand$/;"  c

我寫臨時解決方案：

let s:mapped_buffers = []

autocmd BufReadPost,BufWritePost,BufEnter *.vim call s:MapBuffer()

func s:MapBuffer()
    let nomap = 0
    for buf_i in s:mapped_buffers
        if bufnr('%') == buf_i
            let nomap = 1
        endif
    endfor
    if !nomap
        nnoremap <buffer> <silent> <C-]> :call <SID>JumpToTag()<CR>
        nnoremap <buffer> <silent> <C-W>] :call <SID>JumpToTagInNewWindow()<CR>
        nnoremap <buffer> <silent> g] :call <SID>SelectTag()<CR>
        nnoremap <buffer> <silent> <C-W>g] :call <SID>SelectTagInNewWindow()<CR>
        call add(s:mapped_buffers, bufnr('%'))
    endif
endfunc

func s:JumpToTag()
    exe 'tag ' . s:GetTagName()
endfunc

func s:JumpToTagInNewWindow()
    exe 'stag ' . s:GetTagName()
endfunc

func s:SelectTag()
    exe 'tjump ' . s:GetTagName()
endfunc

func s:SelectTagInNewWindow()
    exe 'stjump ' . s:GetTagName()
endfunc

func s:GetTagName()
    let short_word = expand("<cword>")
    let long_word = expand("<cWORD>")
    let mi = match(long_word, short_word)
    if mi >= 2 && long_word[mi - 1] == ':'
        " Add prefix
        let tag_name = long_word[mi - 2: mi - 1] . short_word
    else
        let tag_name = short_word
    endif
    return tag_name
endfunc

我將以下內容放入~/.vim/after/ftplugin/vim.vim以解決此問題：

if v:version >= 703
    " The runtime update of Vim 7.3.488 (changeset 2cfb68fa26cd) adds ":" to
    " 'iskeyword'; ostensibly "To make syntax highlighting of 'vimVar's work
    " correctly". But this breaks tag jumping, because ctags puts functions
    " without scope prefix into the tags database. (And this is better, because
    " prefixes are sometimes optional, and <SID> and s: are equivalent.)
    setlocal iskeyword-=:
endif
