# rust.vim
## Description
This is a vim plugin provides [Rust][r] file detection and syntax highlighting.
It is synchronized daily to the vim support code in [rust-lang/rust][rr]'s
master branch via cronjob.
## Installation
### Using [Vundle][v]
1. Add `Plugin 'wting/rust.vim'` to `~/.vimrc`
2. `vim +PluginInstall +qall`
*Note:* Vundle will not automatically detect Rust files properly if `filetype
on` is executed before Vundle. Please check the [quickstart][vqs] for more
details.
### Using [Pathogen][p]
1. `cd ~/.vim/bundle`
2. `git clone https://github.com/wting/rust.vim.git`
[rr]: https://github.com/rust-lang/rust
[p]: https://github.com/tpope/vim-pathogen

*rust.txt* Filetype plugin for Rust
==============================================================================
CONTENTS *rust* *ft-rust*
1. Introduction |rust-intro|
2. Settings |rust-settings|
3. Commands |rust-commands|
4. Mappings |rust-mappings|
==============================================================================
INTRODUCTION *rust-intro*
This plugin provides syntax and supporting functionality for the Rust
filetype.
==============================================================================
SETTINGS *rust-settings*
This plugin has a few variables you can define in your vimrc that change the
behavior of the plugin.
*g:rustc_path*
g:rustc_path~
Set this option to the path to rustc for use in the |:RustRun| and
|:RustExpand| commands. If unset, "rustc" will be located in $PATH: >
let g:rustc_path = $HOME."/bin/rustc"
<
*g:rustc_makeprg_no_percent*
g:rustc_makeprg_no_percent~
Set this option to 1 to have 'makeprg' default to "rustc" instead of
"rustc %": >
let g:rustc_makeprg_no_percent = 1
<
*g:rust_conceal*
g:rust_conceal~
Set this option to turn on the basic |conceal| support: >
let g:rust_conceal = 1
<
*g:rust_conceal_mod_path*
g:rust_conceal_mod_path~
Set this option to turn on |conceal| for the path connecting token
"::": >
let g:rust_conceal_mod_path = 1
<
*g:rust_conceal_pub*
g:rust_conceal_pub~
Set this option to turn on |conceal| for the "pub" token: >
let g:rust_conceal_pub = 1
<
*g:rust_recommended_style*
g:rust_recommended_style~
Set this option to enable vim indentation and textwidth settings to
conform to style conventions of the rust standard library (i.e. use 4
spaces for indents and sets 'textwidth' to 99). This option is enabled
by default. To disable it: >
let g:rust_recommended_style = 0
<
*g:rust_fold*
g:rust_fold~
Set this option to turn on |folding|: >
let g:rust_fold = 1
<
Value Effect ~
0 No folding
1 Braced blocks are folded. All folds are open by
default.
2 Braced blocks are folded. 'foldlevel' is left at the
global value (all folds are closed by default).
*g:rust_bang_comment_leader*
g:rust_bang_comment_leader~
Set this option to 1 to preserve the leader on multi-line doc comments
using the /*! syntax: >
let g:rust_bang_comment_leader = 1
<
*g:ftplugin_rust_source_path*
g:ftplugin_rust_source_path~
Set this option to a path that should be prepended to 'path' for Rust
source files: >
let g:ftplugin_rust_source_path = $HOME.'/dev/rust'
<
*g:cargo_manifest_name*
g:cargo_manifest_name~
Set this option to the name of the manifest file for your projects. If
not specified it defaults to 'Cargo.toml' : >
let g:cargo_manifest_name = 'Cargo.toml'
<
==============================================================================
COMMANDS *rust-commands*
:RustRun [args] *:RustRun*
:RustRun! [rustc-args] [--] [args]
Compiles and runs the current file. If it has unsaved changes,
it will be saved first using |:update|. If the current file is
an unnamed buffer, it will be written to a temporary file
first. The compiled binary is always placed in a temporary
directory, but is run from the current directory.
The arguments given to |:RustRun| will be passed to the
compiled binary.
If ! is specified, the arguments are passed to rustc instead.
A "--" argument will separate the rustc arguments from the
arguments passed to the binary.
If |g:rustc_path| is defined, it is used as the path to rustc.
Otherwise it is assumed rustc can be found in $PATH.
:RustExpand [args] *:RustExpand*
:RustExpand! [TYPE] [args]
Expands the current file using --pretty and displays the
results in a new split. If the current file has unsaved
changes, it will be saved first using |:update|. If the
current file is an unnamed buffer, it will be written to a
temporary file first.
The arguments given to |:RustExpand| will be passed to rustc.
This is largely intended for specifying various --cfg
configurations.
If ! is specified, the first argument is the expansion type to
pass to rustc --pretty. Otherwise it will default to
"expanded".
If |g:rustc_path| is defined, it is used as the path to rustc.
Otherwise it is assumed rustc can be found in $PATH.
:RustEmitIr [args] *:RustEmitIr*
Compiles the current file to LLVM IR and displays the results
in a new split. If the current file has unsaved changes, it
will be saved first using |:update|. If the current file is an
unnamed buffer, it will be written to a temporary file first.
The arguments given to |:RustEmitIr| will be passed to rustc.
If |g:rustc_path| is defined, it is used as the path to rustc.
Otherwise it is assumed rustc can be found in $PATH.
:RustEmitAsm [args] *:RustEmitAsm*
Compiles the current file to assembly and displays the results
in a new split. If the current file has unsaved changes, it
will be saved first using |:update|. If the current file is an
unnamed buffer, it will be written to a temporary file first.
The arguments given to |:RustEmitAsm| will be passed to rustc.
If |g:rustc_path| is defined, it is used as the path to rustc.
Otherwise it is assumed rustc can be found in $PATH.
==============================================================================
MAPPINGS *rust-mappings*
This plugin defines mappings for |[[| and |]]| to support hanging indents.
It also has a few other mappings:
*rust_<D-r>*
<D-r> Executes |:RustRun| with no arguments.
Note: This binding is only available in MacVim.
*rust_<D-R>*
<D-R> Populates the command line with |:RustRun|! using the
arguments given to the last invocation, but does not
execute it.
Note: This binding is only available in MacVim.

# Vim Racer Plugin
This plugin allows vim to use [Racer](http://github.com/phildawes/racer) for Rust code completion and navigation.
## Installation
1. Build / Install [Racer](http://github.com/phildawes/racer)
1. Install using Pathogen, Vundle or NeoBundle. Or, copy `plugin/racer.vim` into your `~/.vim/plugin` directory.
Vundle users:
```
Plugin 'racer-rust/vim-racer'
```
NeoBundle users:
```
NeoBundle 'racer-rust/vim-racer'
```
vim-plug users:
```
Plug 'racer-rust/vim-racer'
```
2. Add `g:racer_cmd` and `$RUST_SRC_PATH` variables to your `.vimrc`. Also it's worth turning on 'hidden' mode for buffers otherwise you need to save the current buffer every time you do a goto-definition. E.g.:
```
set hidden
let g:racer_cmd = "<path-to-racer>/target/release/racer"
let $RUST_SRC_PATH="<path-to-rust-srcdir>/src/"
```
3. In insert mode use `C-x-C-o` to search for completions
4. In normal mode type `gd` to go to a definition

" Vim plugin for Racer
" (by Phil Dawes)
"
" 1. Edit the variables below (or override in .vimrc)
" 2. copy this file into .vim/plugin/
" 3. - now in insert mode do 'C-x C-o' to autocomplete the thing at the cursor
" - in normal mode do 'gd' to go to definition
" - 'gD' goes to the definition in a new vertical split
"
" (This plugin is best used with the 'hidden' option enabled so that switching buffers doesn't force you to save)
