もちろん編集にはVimを使っているかと思います。
でも編集だけ？
違うよね！
Vim scriptはウェブアプリケーション記述言語なんだよ！

Plack::Appのアプリケーションハンドラを書いたよ。これを起動するpsgiファイルを用意するよ！app.psgi
#!perl引数の
use lib qw/lib/;
use Plack::Builder;
use Plack::App::Vim;
builder {
mount "/" => Plack::App::Vim->new(server => 'VIM');
};
serverにはclientserver機能が使えるVimを立ち上げ、そのサーバIDを指定しておく必要があるよ！そしてVim側にハンドラを書くよ！
autoload/vimplack.vim
scriptencoding utf-8PSGIプロトコルそのままですね！便利！
function! vimplack#handle(req)
let req = json#decode(a:req)
let res = [200, {}, ["hello world"]]
return json#encode(res)
endfunction
起動しよう！
# plackup app.psgiブラウザで
HTTP::Server::PSGI: Accepting connections at http://0:5000/
http://localhost:5000を開こう！やたー！
あとはアプリケーション書き放題ですね！
試しに掲示板書いてみるよ！
autoload/vimplack.vim
scriptencoding utf-8アプリケーションの更新はVimを再起動するか
let s:comments = get(s:, 'comments', [])
function! vimplack#handle(req)
let req = json#decode(a:req)
if req.uri == "/"
let res = [200, {"Content-Type": "text/html; charset=utf-8"}, [""
\."<html>"
\."<link rel='shortcut icon' href='/static/favicon.ico'>"
\."<title>comment board</title>"
\."<body>"
\."<form action='/regist' method='post'>"
\."コメント:<input type='text' name='comment' value='' /><br />"
\."<input type='submit' value='登録' />"
\."</form>"
\.join(map(copy(s:comments), 'html#encodeEntityReference(v:val)'), '<br />')
\."</body>"
\."</html>"
\]]
elseif req.uri == '/regist' && req.method == 'POST'
let params = {}
for _ in map(split(req.content, '&'), 'split(v:val,"=")')
let params[_[0]] = iconv(http#decodeURI(_[1]), 'utf-8', &encoding)
endfor
if has_key(params, 'comment')
call add(s:comments, params['comment'])
endif
let res = [302, {"Location": "/"}, [""]]
else
let res = [404, {}, ["404 Dan Not Found"]]
endif
return json#encode(res)
endfunction
autoload/vimplack.vimを開いている常態なら
:so %で行けるよ！
知らんかったー
Vim scriptはウェブアプリケーション記述言語やったんやー
