如何直接从vim运行lang代码？

Question

如何直接从go lang投放code vim editor？

e.g。当前编辑的文件为array.go。 我应该使用什么样的命令在vim中运行此代码？

Answer 1

好的，所以经过一些试验后，这可行：!go run %

Answer 2

假设您已正确设置环境变量;您可以使用此_gvimrc文件（在Windows上，它应该在C:\Users\UserName;在Linux上，我不知道）：

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

现在，当您按F5时，它将运行go（go run file.go）并在另一个文档中显示输出（您可以:q关闭另一个文档）。其他命令包括：​​F6构建，F7安装，F9测试和（我心爱的人）F10 fmt + :w。

BTW dejavu是我最喜欢的颜色方案（代码来自gorilla / mux）：

Answer 3

您也可以像这样映射 ~/.vimrc 中的键

nnoremap gr :!go run %<CR>

因此您可以轻松地在 vim 中输入 gr 并执行。

Answer 4

将以下两行添加到您的 vimrc 中。

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>

这是受an answer to a similar python question
