vim with syntastic and eslint: show warnings
提问by Jonathan.Brink
I'm using Vim with the syntasticplugin and eslint.
我将 Vim 与Syntastic插件和 eslint 一起使用。
When I save a JavaScript file, I can see errors come up just fine, but I can't get the warnings to show.
当我保存 JavaScript 文件时，我可以看到错误出现得很好，但我无法显示警告。
Here's what I have in my .vimrc:
这是我的 .vimrc 中的内容：
let g:syntastic_javascript_checkers = ['eslint']
让 g:syntastic_javascript_checkers = ['eslint']
I installed eslint with:
我安装了 eslint：
npm install eslint -g
npm 安装 eslint -g

How do I get warnings to appear?
如何让警告出现？
采纳答案by Jonathan.Brink
It turns out the issue here was that the "warnings" I thought I had in my file were not actually warnings. When I put an actualwarning in my file it showed up correctly.
事实证明，这里的问题是我认为我的文件中的“警告”实际上并不是警告。当我在文件中添加实际警告时，它显示正确。
Some advice I learned though was to first run the file on the command-line directly using eslint similar to this:
我学到的一些建议是首先使用类似于以下的 eslint 在命令行上直接运行文件：
eslint /path/to/file.js
Then compare those results to what you see in Vim.
然后将这些结果与您在 Vim 中看到的结果进行比较。
Another tip is that you can change rules on the fly with comment syntax like this:
另一个提示是，您可以使用如下注释语法动态更改规则：
/*eslint <rule>=1*/

I really don't know if it will help you, but I will put it here. I had a similar problem but in my case it was related to the version of syntastic, so a simple git pullsolved it. My vim configuration is somewhat canonical, so I will share that:
我真的不知道它是否对你有帮助，但我会把它放在这里。我有一个类似的问题，但在我的情况下它与 Syntastic 的版本有关，所以一个简单的git pull解决了它。我的 vim 配置有点规范，所以我将分享：
let g:syntastic_mode_map = { 'mode': 'active',
\ 'active_filetypes': ['python', 'javascript'],
\ 'passive_filetypes': [] }
set statusline+=%#warningmsg#
set statusline+=%{SyntasticStatuslineFlag()}
set statusline+=%*
let g:syntastic_always_populate_loc_list = 1
let g:syntastic_auto_loc_list = 1
let g:syntastic_check_on_open = 1
let g:syntastic_check_on_wq = 0
let g:syntastic_javascript_checkers = ['eslint']
When you open your file that contains some mistakes, it should show that into the error window.
当您打开包含一些错误的文件时，它应该将其显示在错误窗口中。
