快速修正（Quickfix）

1. 使用快速修正命令 Quickfix E42

vim -q filename

:cexpr system('grep -n xyz *')
:cexpr getline(1, '$')

:g/mypattern/caddexpr expand("%") .. ":" .. line(".") ..  ":" .. getline(".")

function QfMakeConv()
   let qflist = getqflist()
   for i in qflist
      let i.text = iconv(i.text, "cp936", "utf-8")
   endfor
   call setqflist(qflist)
endfunction
au QuickfixCmdPost make call QfMakeConv()

call setqflist([], 'a', {'title' : 'Cmd output'})
echo getqflist({'title' : 1})
call setloclist(3, [], 'a', {'title' : 'Cmd output'})
echo getloclist(3, {'title' : 1})

echo getqflist({'idx' : 0}).idx
echo getqflist({'id' : qfid, 'idx' : 0}).idx
echo getloclist(2, {'idx' : 0}).idx

call setqflist([], 'a', {'idx' : 12})
call setqflist([], 'a', {'id' : qfid, 'idx' : 7})
call setloclist(1, [], 'a', {'idx' : 7})

echo getqflist({'size' : 1})
echo getloclist(5, {'size' : 1})

let somectx = {'name' : 'Vim', 'type' : 'Editor'}
call setqflist([], 'a', {'context' : somectx})
echo getqflist({'context' : 1})
let newctx = ['red', 'green', 'blue']
call setloclist(2, [], 'a', {'id' : qfid, 'context' : newctx})
echo getloclist(2, {'id' : qfid, 'context' : 1})

echo getqflist({'lines' : ["F1:10:Line10", "F2:20:Line20"]})
echo getqflist({'lines' : systemlist('grep -Hn quickfix *')})

echo getqflist({'efm' : '%f#%l#%m', 'lines' : ['F1#10#Line']})

:cfirst

etc.

:10,$cdo cmd

etc.

:lfirst

etc.

:lfirst

2. 錯誤視窗 quickfix-window

:botright cwindow

:call setloclist(0, [], ' ', {'lines' : systemlist('grep -Hn main *.c')})
" replace the location list entries for the third window
:call setloclist(3, [], 'r', {'items' : newItems})

3. 使用多個錯誤列表 quickfix-error-lists

  error list 1 of 3; 43 errors   :make
> error list 2 of 3; 0 errors    :helpgrep tag
  error list 3 of 3; 15 errors   :grep ex_help *.c

" Make the 4th quickfix list current
:4chistory

echo getqflist({'nr' : '$'}).nr
echo getloclist(3, {'nr' : '$'}).nr

echo getqflist({'nr' : 0}).nr

4. 使用 :make :make_makeprg

:set makeprg=make\ #<.o

:set makeprg=latex\ \\\\nonstopmode\ \\\\input\\{$*}

:let &mp = 'latex \\nonstopmode \\input\{$*}'

:set makeprg=gcc\ -o\ $*\ $*

function QfMakeConv()
   let qflist = getqflist()
   for i in qflist
      let i.text = iconv(i.text, "cp936", "utf-8")
   endfor
   call setqflist(qflist)
endfunction
au QuickfixCmdPost make call QfMakeConv()

5. 使用 :vimgrep 和 :grep grep lid

command! -nargs=+ NewGrep execute 'silent grep! <args>' | copen 42

:vimgrep /an error/ *.c
:vimgrep /\<FileName\>/ *.h include/*
:vimgrep /myfunc/ **/*.c

:vimgrep Error *.c

:call setqflist([])
:bufdo grepadd! something %

:silent argdo try
  \ | grepadd! something %
  \ | catch /E480:/
  \ | endtry"

:grep foo *.c

:set grepprg=lid\ -Rgrep\ -s
:set grepformat=%f:%l:%m

:grep (regexp)

:vimgrep /\<read_file\>/ *.c

:vimgrep /\<msg\>/ *.c

:colder

6. 選擇編譯器 compiler-select

CPPCHECK quickfix-cppcheck compiler-cppcheck

let &l:path = join(systemlist('git ls-tree -d --name-only -r HEAD'), ',')

DOTNET compiler-dotnet

let dotnet_errors_only = v:true
let dotnet_show_project_file = v:false
compiler dotnet

GCC quickfix-gcc compiler-gcc

JAVAC compiler-javac

let g:javac_makeprg_params = "-Xlint:all -encoding utf-8"

GNU MAKE compiler-make

GROFF quickfix-groff compiler-groff

PANDOC quickfix-pandoc compiler-pandoc

PERL quickfix-perl compiler-perl

let g:perl_compiler_force_warnings = 0

PYUNIT COMPILER compiler-pyunit

TEX COMPILER compiler-tex

:let b:tex_flavor = 'amstex'
:compiler tex

:make mypaper

TYPST COMPILER compiler-typst

let g:typst_cmd = "/path/to/other/command"

7. 錯誤格式 error-file-format

^

---------^

:set efm=%EError\ %n,%Cline\ %l,%Ccolumn\ %c,%Z%m

:set efm=%C\ %.%#,%A\ \ File\ \"%f\"\\,\ line\ %l%.%#,%Z%[%^\ ]%\\@=%m

:set efm=xxx,%E%>Error in line %l of %f:,%Z%m

setlocal efm=aa,bb,cc,dd,ee

:set efm=%+P[%f],(%l\\,%c)%*[\ ]%t%*[^:]:\ %m,%-Q

{"file1" {"file2" error1} error2 {"file3" error3 {"file4" error4 error5}}}

:set mp=make\ \\\|&\ error_filter

8. 目錄堆疊 quickfix-directory-stack

9. 特定錯誤檔案格式 errorformats

10. 自訂 Quickfix 視窗 quickfix-window-function

<filename>|<lnum> col <col>|<text>

" create a quickfix list from v:oldfiles
call setqflist([], ' ', {'lines' : v:oldfiles, 'efm' : '%f',
                                    \ 'quickfixtextfunc' : 'QfOldFiles'})
func QfOldFiles(info)
    " get information about a range of quickfix entries
    let items = getqflist({'id' : a:info.id, 'items' : 1}).items
    let l = []
    for idx in range(a:info.start_idx - 1, a:info.end_idx - 1)
        " use the simplified file name
      call add(l, fnamemodify(bufname(items[idx].bufnr), ':p:.'))
    endfor
    return l
endfunc
