如何直接从vim运行go lang代码？

Question

How to run go lang code directly from vim editor ?

eg currently edited file is array.go . What kind of commands should I use to run this code in vim?

Answer 1

好的，经过一些试验后，这有效： !go run %

Answer 2

Assuming that you've set environment variables properly; you can use this _gvimrc file (on Windows, it should be at C:\\Users\\UserName ; on Linux, I do not know):

set guifont=Lucida_Console:h11
colorscheme dejavu
set tabstop=4

filetype plugin on
filetype plugin indent on
syntax on

" causes vim opens maximized in windows (@least)
au GUIEnter * simalt ~x

set autochdir
set number
set nobackup
" set nowritebackup

" this made my vim life (as a begginer at least) much happier!

function! s:ExecuteInShell(command, bang)
    let _ = a:bang != '' ? s:_ : a:command == '' ? '' : join(map(split(a:command), 'expand(v:val)'))

    if (_ != '')
        let s:_ = _
        let bufnr = bufnr('%')
        let winnr = bufwinnr('^' . _ . '$')
        silent! execute  winnr < 0 ? 'belowright new ' . fnameescape(_) : winnr . 'wincmd w'
        setlocal buftype=nowrite bufhidden=wipe nobuflisted noswapfile wrap number
        silent! :%d
        let message = 'Execute ' . _ . '...'
        call append(0, message)
        echo message
        silent! 2d | resize 1 | redraw
        silent! execute 'silent! %!'. _
        silent! execute 'resize ' . line('$')
        silent! execute 'syntax on'
        silent! execute 'autocmd BufUnload <buffer> execute bufwinnr(' . bufnr . ') . ''wincmd w'''
        silent! execute 'autocmd BufEnter <buffer> execute ''resize '' .  line(''$'')'
        silent! execute 'nnoremap <silent> <buffer> <CR> :call <SID>ExecuteInShell(''' . _ . ''', '''')<CR>'
        silent! execute 'nnoremap <silent> <buffer> <LocalLeader>r :call <SID>ExecuteInShell(''' . _ . ''', '''')<CR>'
        silent! execute 'nnoremap <silent> <buffer> <LocalLeader>g :execute bufwinnr(' . bufnr . ') . ''wincmd w''<CR>'
        nnoremap <silent> <buffer> <C-W>_ :execute 'resize ' . line('$')<CR>
        silent! syntax on
    endif
endfunction

command! -complete=shellcmd -nargs=* -bang Shell call s:ExecuteInShell(<q-args>, '<bang>')
cabbrev shell Shell

" my additional tools
command! -complete=shellcmd -nargs=* -bang Gor call s:ExecuteInShell('go run %', '<bang>')
command! -complete=shellcmd -nargs=* -bang Gon call s:ExecuteInShell('go install', '<bang>')
command! -complete=shellcmd -nargs=* -bang Gob call s:ExecuteInShell('go build', '<bang>')
command! -complete=shellcmd -nargs=* -bang Got call s:ExecuteInShell('go test -v', '<bang>')

:map <F5>  :Gor<CR>
:map <F6>  :Gob<CR>
:map <F7>  :Gon<CR>
:map <F9>  :Got<CR>
:map <F10> :Fmt<CR>:w<CR>
:map <F12> :q<CR>

cabbrev fmt Fmt

:set encoding=utf-8
:set fileencodings=utf-8

Now when you press F5 it will run go ( go run file.go ) and shows the output in another document (you can :q to close the other document). Other commands are: F6 build, F7 install, F9 test and (my beloved one) F10 is fmt + :w .

BTW dejavu is my favorite color-scheme (code is from gorilla/mux):

Answer 3

You can also map a key in your ~/.vimrc as this

nnoremap gr :!go run %<CR>

So you can easily type gr in your vim and it will execute.

Answer 4

add the following two lines to your vimrc.

autocmd FileType go map <buffer> <F9> :w<CR>:exec '!go run' shellescape(@%, 1)<CR>

autocmd FileType go imap <buffer> <F9> <esc>:w<CR>:exec '!go run' shellescape(@%, 1)<CR>

this is inspired by an answer to a similar python question
