# 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.
## License
Like Rust, rust.vim is primarily distributed under the terms of both the MIT
license and the Apache License (Version 2.0). See LICENSE-APACHE and
LICENSE-MIT for details.

*ft_rust.txt* Filetype plugin for Rust
==============================================================================
CONTENTS *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. It requires Vim 8 or higher for full functionality. Some commands
will not work on earlier versions.
==============================================================================
SETTINGS *rust-settings*
This plugin has a few variables you can define in your vimrc that change the
behavior of the plugin.
Some variables can be set buffer local (`:b` prefix), and the buffer local
will take precedence over the global `g:` counterpart.
*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:rust_use_custom_ctags_defs*
g:rust_use_custom_ctags_defs~
Set this option to 1 if you have customized ctags definitions for Rust
and do not wish for those included with rust.vim to be used: >
let g:rust_use_custom_ctags_defs = 1
<
NOTE: rust.vim's built-in definitions are only used for the Tagbar Vim
plugin, if you have it installed, AND if Universal Ctags is not
detected. This is because Universal Ctags already has built-in
support for Rust when used with Tagbar.
Also, note that when using ctags other than Universal Ctags, it is not
automatically used when generating |tags| files that Vim can use to
navigate to definitions across different source files. Feel free to
copy `rust.vim/ctags/rust.ctags` into your own `~/.ctags` if you wish
to generate |tags| files.
*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:rustfmt_command*
g:rustfmt_command~
Set this option to the name of the 'rustfmt' executable in your $PATH. If
not specified it defaults to 'rustfmt' : >
let g:rustfmt_command = 'rustfmt'
<
*g:rustfmt_autosave*
g:rustfmt_autosave~
Set this option to 1 to run |:RustFmt| automatically when saving a
buffer. If not specified it defaults to 0 : >
let g:rustfmt_autosave = 0
<
There is also a buffer-local b:rustfmt_autosave that can be set for
the same purpose, and can override the global setting.
*g:rustfmt_autosave_if_config_present*
g:rustfmt_autosave_if_config_present~
Set this option to 1 to have *b:rustfmt_autosave* be set automatically
if a `rustfmt.toml` file is present in any parent directly leading to
the file being edited. If not set, default to 0: >
let g:rustfmt_autosave_if_config_present = 0
<
This is useful to have `rustfmt` only execute on save, on projects
that have `rustfmt.toml` configuration.
There is also a buffer-local b:rustfmt_autosave_if_config_present
that can be set for the same purpose, which can overrides the global
setting.
*g:rustfmt_fail_silently*
g:rustfmt_fail_silently~
Set this option to 1 to prevent 'rustfmt' from populating the
|location-list| with errors. If not specified it defaults to 0: >
let g:rustfmt_fail_silently = 0
<
*g:rustfmt_options*
g:rustfmt_options~
Set this option to a string of options to pass to 'rustfmt'. The
write-mode is already set to 'overwrite'. If not specified it
defaults to '' : >
let g:rustfmt_options = ''
<
*g:rustfmt_emit_files*
g:rustfmt_emit_files~
If not specified rust.vim tries to detect the right parameter to
pass to rustfmt based on its reported version. Otherwise, it
determines whether to run rustfmt with '--emit=files' (when 1 is
provided) instead of '--write-mode=overwrite'. >
let g:rustfmt_emit_files = 0
*g:rust_playpen_url*
g:rust_playpen_url~
Set this option to override the url for the playpen to use: >
let g:rust_playpen_url = 'https://play.rust-lang.org/'
<
*g:rust_shortener_url*
g:rust_shortener_url~
Set this option to override the url for the url shortener: >
let g:rust_shortener_url = 'https://is.gd/'
<
*g:rust_clip_command*
g:rust_clip_command~
Set this option to the command used in your OS to copy the Rust Play
url to the clipboard: >
let g:rust_clip_command = 'xclip -selection clipboard'
<
*g:cargo_makeprg_params*
g:cargo_makeprg_params~
Set this option to the string of parameters to pass to cargo. If not
specified it defaults to '$*' : >
let g:cargo_makeprg_params = 'build'
<
*g:cargo_shell_command_runner*
g:cargo_shell_command_runner~
Set this option to change how to run shell commands for cargo commands
|:Cargo|, |:Cbuild|, |:Crun|, ...
By default, |:terminal| is used to run shell command in terminal window
asynchronously. But if you prefer |:!| for running the commands, it can
be specified: >
let g:cargo_shell_command_runner = '!'
<
Integration with Syntastic *rust-syntastic*
--------------------------
This plugin automatically integrates with the Syntastic checker. There are two
checkers provided: 'rustc', and 'cargo'. The latter invokes 'Cargo' in order to
build code, and the former delivers a single edited '.rs' file as a compilation
target directly to the Rust compiler, `rustc`.
Because Cargo is almost exclusively being used for building Rust code these
days, 'cargo' is the default checker. >
let g:syntastic_rust_checkers = ['cargo']
<
If you would like to change it, you can set `g:syntastic_rust_checkers` to a
different value.
*g:rust_cargo_avoid_whole_workspace*
*b:rust_cargo_avoid_whole_workspace*
g:rust_cargo_avoid_whole_workspace~
When editing a crate that is part of a Cargo workspace, and this
option is set to 1 (the default), then 'cargo' will be executed
directly in that crate directory instead of in the workspace
directory. Setting 0 prevents this behavior - however be aware that if
you are working in large workspace, Cargo commands may take more time,
plus the Syntastic error list may include all the crates in the
workspace. >
let g:rust_cargo_avoid_whole_workspace = 0
<
*g:rust_cargo_check_all_targets*
*b:rust_cargo_check_all_targets*
g:rust_cargo_check_all_targets~
When set to 1, the `--all-targets` option will be passed to cargo when
Syntastic executes it, allowing the linting of all targets under the
package.
The default is 0.
*g:rust_cargo_check_all_features*
*b:rust_cargo_check_all_features*
g:rust_cargo_check_all_features~
When set to 1, the `--all-features` option will be passed to cargo when
Syntastic executes it, allowing the linting of all features of the
package.
The default is 0.
*g:rust_cargo_check_examples*
*b:rust_cargo_check_examples*
g:rust_cargo_check_examples~
When set to 1, the `--examples` option will be passed to cargo when
Syntastic executes it, to prevent the exclusion of examples from
linting. The examples are normally under the `examples/` directory of
the crate.
The default is 0.
*g:rust_cargo_check_tests*
*b:rust_cargo_check_tests*
g:rust_cargo_check_tests~
When set to 1, the `--tests` option will be passed to cargo when
Syntastic executes it, to prevent the exclusion of tests from linting.
The tests are normally under the `tests/` directory of the crate.
The default is 0.
*g:rust_cargo_check_benches*
*b:rust_cargo_check_benches*
g:rust_cargo_check_benches~
When set to 1, the `--benches` option will be passed to cargo when
Syntastic executes it. The benches are normally under the `benches/`
directory of the crate.
The default is 0.
Integration with auto-pairs *rust-auto-pairs*
---------------------------
This plugin automatically configures the auto-pairs plugin not to duplicate
single quotes, which are used more often for lifetime annotations than for
single character literals.
*g:rust_keep_autopairs_default*
g:rust_keep_autopairs_default~
Don't override auto-pairs default for the Rust filetype. The default
is 0.
==============================================================================
COMMANDS *rust-commands*
Invoking Cargo
--------------
This plug defines very simple shortcuts for invoking Cargo from with Vim.
:Cargo <args> *:Cargo*
Runs 'cargo' with the provided arguments.
:Cbuild <args> *:Cbuild*
Shortcut for 'cargo build`.
:Cclean <args> *:Cclean*
Shortcut for 'cargo clean`.
:Cdoc <args> *:Cdoc*
Shortcut for 'cargo doc`.
:Cinit <args> *:Cinit*
Shortcut for 'cargo init`.
:Crun <args> *:Crun*
Shortcut for 'cargo run`.
:Ctest <args> *:Ctest*
Shortcut for 'cargo test`.
:Cupdate <args> *:Cupdate*
Shortcut for 'cargo update`.
:Cbench <args> *:Cbench*
Shortcut for 'cargo bench`.
:Csearch <args> *:Csearch*
Shortcut for 'cargo search`.
:Cpublish <args> *:Cpublish*
Shortcut for 'cargo publish`.
:Cinstall <args> *:Cinstall*
Shortcut for 'cargo install`.
:Cruntarget <args> *:Cruntarget*
Shortcut for 'cargo run --bin' or 'cargo run --example',
depending on the currently open buffer.
Formatting
----------
:RustFmt *:RustFmt*
Runs |g:rustfmt_command| on the current buffer. If
|g:rustfmt_options| is set then those will be passed to the
executable.
If |g:rustfmt_fail_silently| is 0 (the default) then it
will populate the |location-list| with the errors from
|g:rustfmt_command|. If |g:rustfmt_fail_silently| is set to 1
then it will not populate the |location-list|.
:RustFmtRange *:RustFmtRange*
Runs |g:rustfmt_command| with selected range. See
|:RustFmt| for any other information.
Playpen integration
-------------------
:RustPlay *:RustPlay*
This command will only work if you have web-api.vim installed
(available at https://github.com/mattn/webapi-vim). It sends the
current selection, or if nothing is selected, the entirety of the
current buffer to the Rust playpen, and emits a message with the
shortened URL to the playpen.
|g:rust_playpen_url| is the base URL to the playpen, by default
"https://play.rust-lang.org/".
|g:rust_shortener_url| is the base url for the shorterner, by
default "https://is.gd/"
|g:rust_clip_command| is the command to run to copy the
playpen url to the clipboard of your system.
Evaluation of a single Rust file
--------------------------------
NOTE: These commands are useful only when working with standalone Rust files,
which is usually not the case for common Rust development. If you wish to
building Rust crates from with Vim can should use Vim's make, Syntastic, or
functionality from other plugins.
: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.
Running test(s)
---------------
:[N]RustTest[!] [options] *:RustTest*
Runs a test under the cursor when the current buffer is in a
cargo project with "cargo test" command. If the command did
not find any test function under the cursor, it stops with an
error message.
When N is given, adjust the size of the new window to N lines
or columns.
When ! is given, runs all tests regardless of current cursor
position.
When [options] is given, it is passed to "cargo" command
arguments.
When the current buffer is outside cargo project, the command
runs "rustc --test" command instead of "cargo test" as
fallback. All tests are run regardless of adding ! since there
is no way to run specific test function with rustc. [options]
is passed to "rustc" command arguments in the case.
Takes optional modifiers (see |<mods>|): >
:tab RustTest
:belowright 16RustTest
:leftabove vert 80RustTest
<
rust.vim Debugging
------------------
:RustInfo *:RustInfo*
Emits debugging info of the Vim Rust plugin.
:RustInfoToClipboard *:RustInfoClipboard*
Saves debugging info of the Vim Rust plugin to the default
register.
:RustInfoToFile [filename] *:RustInfoToFile*
Saves debugging info of the Vim Rust plugin to the the given
file, overwritting it.
==============================================================================
MAPPINGS *rust-mappings*
This plugin defines mappings for |[[| and |]]| to support hanging indents.
