vim - Vim + elm-vim 无法识别 .elm 文件

问题描述

我刚开始用 elm 编程，我正在用 vim 设置我的配置，但我遇到了一些麻烦。

我已经下载了elm-vim，但是当我创建一个 .elm 文件时，我没有语法高亮显示，Ale 不起作用（它没有显示任何建议/错误）......就像我没有安装 elm 插件一样。

我安装了以下全局 elm 软件包：

$ npm list -g | grep elm
├─┬ elm@0.19.1-3
├─┬ elm-format@0.8.2
├── elm-oracle@1.1.1
├─┬ elm-test@0.19.1-revision2
│ ├─┬ elmi-to-json@1.3.0
│ ├─┬ node-elm-compiler@5.0.4
│ │ ├─┬ find-elm-dependencies@2.0.2

这是我的.vimrc：

解决方案

TL;DR：从 vimrc 文件的顶部删除这些行：

filetype plugin on
filetype indent on

那应该可以解决问题。

您遇到的问题是filetype=elm与*.elm文件关联的 elm-vim 的文件类型检测没有被加载，即使插件本身已成功注册。

Elm 中的文件类型检测由~/.vim/bundle/elm-vim/ftdetect/elm.vim您设置中的脚本完成，但该脚本永远不会被加载。

ftdetect脚本在 Vim 中作为执行的一部分加载，$VIMRUNTIME/filetype.vim其中包含以下代码段：

" Use the filetype detect plugins.  They may overrule any of the previously
" detected filetypes.
runtime! ftdetect/*.vim

该filetype.vim文件作为:filetype on命令的一部分运行，因此这就是autocmd为文件类型检测创建所有 s 的原因。

但是，filetype.vim还包括此代码段：

" Listen very carefully, I will say this only once
if exists("did_load_filetypes")
  finish
endif
let did_load_filetypes = 1

这意味着在启用文件类型检测时，该文件只会被获取一次。如果要重新运行它，则需要禁用它（使用:filetype off，运行$VIMRUNTIME/ftoff.vim，取消设置did_load_filetypes全局变量），然后才能再次重新启用它。

这就是为什么 Vundle 会filetype plugin indent on在调用 后告诉您立即运行vundle#end()，因为此时'runtimepath'将已调整为包含插件路径，并且ftdetect将找到来自插件的所有目录。它还会告诉您在filetype off之前运行vundle#begin()以确保它被禁用（它可能已从defaults.vim系统范围的 vimrc 文件中启用。）请参阅Vundle 的快速入门，其中列出了所需的两个步骤。

因此，简而言之，仅在 Vundle 插件设置完成后使用:filetype on命令（或者更具体地说，filetype plugin indent on） 。如果您以前也这样做过，那么您很可能会错过您的插件，因为这些脚本不会被获取。ftdetect
