# rust.vim

## Description

This is a Vim plugin that provides [Rust][r] file detection, syntax highlighting, formatting,
[Syntastic][syn] integration, and more. It requires Vim 8 or higher for full functionality.
Some things may not work on earlier versions. 

## Installation

For activating the full functionality, this plugin requires either the plugin
manager or the `.vimrc` to have the following:

```vim
syntax enable
filetype plugin indent on
```

Most plugin managers don't do this automatically, so these statements are
usually added by users in their `vimrc` _right after_ the plugin manager load
section.

### [Vim8 packages][vim8pack]

```sh
git clone https://github.com/rust-lang/rust.vim ~/.vim/pack/plugins/start/rust.vim
```

### [Vundle][v]

```vim
Plugin 'rust-lang/rust.vim'
```

### [Pathogen][p]

```sh
git clone --depth=1 https://github.com/rust-lang/rust.vim.git ~/.vim/bundle/rust.vim
```

### [vim-plug][vp]

```vim
Plug 'rust-lang/rust.vim'
```

### [dein.vim][d]

```vim
call dein#add('rust-lang/rust.vim')
```

### [NeoBundle][nb]

```vim
NeoBundle 'rust-lang/rust.vim'
```

## Features

### Error checking with [Syntastic][syn]

`rust.vim` automatically registers `cargo` as a syntax checker with
[Syntastic][syn], if nothing else is specified. See `:help rust-syntastic`
for more details.

### Source browsing with [Tagbar][tgbr]

The installation of Tagbar along with [Universal Ctags][uctags] is recommended
for a good Tagbar experience. For other kinds of setups, `rust.vim` tries to
configure Tagbar to some degree.

### Formatting with [rustfmt][rfmt]

The `:RustFmt` command will format your code with
[rustfmt][rfmt] if installed. `rustfmt` can be installed
via `rustup component add rustfmt`.

Placing `let g:rustfmt_autosave = 1` in your `~/.vimrc` will
enable automatic running of `:RustFmt` when you save a buffer.

Do `:help :RustFmt` for further formatting help and customization
options.

### [Playpen][pp] integration

*Note:* This feature requires [webapi-vim][wav] to be installed.

The `:RustPlay` command will send the current selection, or if
nothing is selected the current buffer, to the [Rust playpen][pp].

If you set g:rust_clip_command RustPlay will copy the url to the clipboard.

- Mac:

      let g:rust_clip_command = 'pbcopy'

- Linux:

      let g:rust_clip_command = 'xclip -selection clipboard'

### Running a test under cursor

In a Cargo project, the `:RustTest` command will run the test that is under the cursor.
This is useful when your project is big and running all of the tests takes a long time.

## Help

Further help can be found in the documentation with `:Helptags` then `:help rust`.

Detailed help can be found in the documentation with `:help rust`.
Helptags (`:help helptags`) need to be generated for this plugin
in order to navigate the help. Most plugin managers will do this
automatically, but check their documentation if that is not the case.
