Overview

Racer - code completion for Rust

RACER = Rust Auto-Complete-er. A utility intended to provide Rust code completion for editors and IDEs. Maybe one day the 'er' bit will be exploring + refactoring or something.

Installation

NOTE From 2.1, racer needs nightly rust

Requirements

Current nightly Rust

If you're using rustup, run

rustup toolchain add nightly

Cargo

Internally, racer calls cargo as a CLI tool, so please make sure cargo is installed

With `cargo install`

Simply run:

cargo +nightly install racer

As mentioned in the command output, don't forget to add the installation directory to your PATH.

From sources

Clone the repository: git clone https://github.com/racer-rust/racer.git
cd racer; cargo +nightly build --release. The binary will now be in ./target/release/racer
Add the binary to your PATH. This can be done by moving it to a directory already in your PATH (i.e. /usr/local/bin) or by adding the ./target/release/ directory to your PATH

Configuration

Fetch the Rust sourcecode
1. automatically via rustup and run rustup component add rust-src in order to install the source to $(rustc --print sysroot)/lib/rustlib/src/rust/library (or $(rustc --print sysroot)/lib/rustlib/src/rust/src in older toolchains). Rustup will keep the sources in sync with the toolchain if you run rustup update.
2. manually from git: https://github.com/rust-lang/rust
Note

If you want to use racer with multiple release channels (Rust has 3 release channels: stable, beta and nightly), you have to also download Rust source code for each release channel you install.

e.g. (rustup case) Add a nightly toolchain build and install nightly sources too

rustup toolchain add nightly

rustup component add rust-src
(Optional) Set RUST_SRC_PATH environment variable to point to the 'src' dir in the Rust source installation e.g. % export RUST_SRC_PATH=$(rustc --print sysroot)/lib/rustlib/src/rust/library or % export RUST_SRC_PATH="$(rustc --print sysroot)/lib/rustlib/src/rust/src" (older)

It's recommended to set RUST_SRC_PATH for speed up, but racer detects it automatically if you don't set it.
Test on the command line:

racer complete std::io::B (should show some completions)

Note

To complete names in external crates, Racer needs Cargo.lock. So, when you add a dependency in your Cargo.toml, you have to run a build command such as cargo build or cargo test, to get completions.

Editors/IDEs Supported

RLS

Racer is used as a static library in RLS

Eclipse integration

Racer can be used with Eclipse through the use of RustDT. (User guide is linked in repo description)

Emacs integration

Emacs integration has been moved to a separate project: emacs-racer.

Gedit integration

Gedit integration can be found here.

Builder integration

Gnome Builder integration can be found here

Kate integration

The Kate community maintains a plugin. It is bundled with recent releases of Kate (tested with 16.08 - read more here).

Enable 'Rust code completion' in the plugin list in the Kate config dialog;
On the new 'Rust code completion' dialog page, make sure 'Racer command' and 'Rust source tree location' are set correctly.

Sublime Text integration

The Sublime Text community maintains some packages that integrates Racer

RustAutoComplete that offers auto completion and goto definition.
AnacondaRUST from the anaconda plugins family that offers auto completion, goto definition and show documentation

Vim integration

Vim integration has been moved to a separate project: vim-racer.

Visual Studio Code extension

Racer recommends the official Rust (rls) extension based on RLS, which uses Racer for completion.

Atom integration

You can find the racer package for Atom here

Kakoune integration

Kakoune comes with a builtin integration for racer auto completion.

Auto-completion without source code?

It seems like it is taken for granted that source code is always availble. What if we have a proprietary dynamic library (with API documentation) but no source code, is there anyway we can use racer to gives us auto completion based on this?

Split racer into executable and library.

I have a proof-of-concept for this set up in my fork, but it's only good enough to compile at this point and could probably use some additional refactoring and/or renaming.

My motivation for this is to let the library contain the bulk of the logic and heavy lifting so that multiple clients can target the same functionality. The existing racer client is nice for text editors that execute it directly, but it would be nice to have support for a client that can do things like integrate with gnome-code-assistance by communicating over DBus rather than standard output and arguments to main, and I'm sure there are other use cases where this would be nice to have as well.

Use the new Thread API to sandbox libsyntax use

This allows RACER to continue processing even when libsyntax crashes. This is vital if we wish to use RACER as say, a library in the future.

This fixes the issue of racer crashing

I realize that this commit sort of undoes this one where the threading code was removed, but from what I read on the issue tracker, that code was removed since Rust's behaviour changed and allowed panic!(...) to leak between threads.

Since the leaking of panic!(...) does not happen, I think that this error handling must be reintroduced, regardless of performance cost (yes, this does have some performance penalty)

Automatic source discovery with rust's new `rust-src` package

Rust now has an "official" location to install sources to (<toolchain root>/lib/rustlib/src/rust). Although there is no separate installer for this new component, it can be installed via rustup.

edit: scratch everything that was previously here, I'm an idiot :disappointed:

It's as simple as racer calling rustc --print sysroot and locating the source that way. This will then seamlessly work with rustup.

External crate completions don't work without extern crate declaration
Steps to repoduce:

Create a new project: cargo new temp

Add a dependency, e.g. rand = "0.6.5"

cargo build

Try to complete use rand:: (I tested it with vim). It won't work.

Add extern crate rand; and try again. It will.

Read substitute file from stdin
Hello!

Not all editors use temp-files (or don't expose them to plugin authors). I made it possible for the substitute file to be read from stdin if you specify "-" as the substitute_file.

Is this functionality something you would be interested in merging? In that case i will continue to work on it. There are a few things that still needs doing.

Check/fix for daemon mode

Make testable and add tests

If you are curious, I am working on a plugin for Visual Studio Code.

The plugin is located at https://github.com/henriiik/vscode-rust.

Provide a completer to YCM

Great work on racer! This will be super useful once it is more dynamic.

https://github.com/Valloric/YouCompleteMe is a code completion plugin for Vim that is very sophisticated. It provides IDE like completion for C++ but integrates with other completers too. I use it for python, c++ and java and love it in all languages.

YCM has solved the UI problem in Vim completely, racer should be a completer for it in Vim, not a stand alone plugin.

replace cargo.rs with cargo
Current racer's file search has many problems. Sometimes it fails to find dependency(see comments in #551), and it causes too much recursion(#831). To resolve these problems, I replaced cargo.rs with cargo crate. For clients which does sync io, this change can cause 2~3s delay when downloading dependencies, but other than that, it works well.

To work with cargo, current tests implementation have some problems.

Currently we use env::set_current_dir for test_project, but it doesn't work with cargo.

It uses our own TmpDir implementation, which creates directory under racer/. So if a test panics it leaves tempdir in our normal file system. It's a bit annoying.

So I implemented new with_test_project function which copies whole files into tempdir and then run tests in that directory. And I replace racer's TmpDir with tempfile crate and remove sync! macro in each tests. Each test directories have unique names so there's no need to lock threads. Now tests are much faster.

In addition, I want to leave some notes about dependency caching. Here we have cached dependencies for each manifest files(i.e. Cargo.toml), because racer calls get_crate_file many times in a session. Compared to @birkenfeld's way in #838, it has 2 differences.

It doesn't have caches of crate roots. It call's cargo::util::important_paths::find_root_manifest_for_wd everytime. This is because I think it can't be bottleneck.

It has dependency cache in Session, not in thread_local global variable. It can cause decrease in speed for clients using racer as library like rls. This is because I think to use thread_local make difficult to provide stateful APIs in the future, but I have no strong opinion about this.

And here's a result of benchmark, though it's not so general(We need more practical bench, but it will be a future task). Before

test benches::bench_code_chunks ... bench: 86,014 ns/iter (+/- 5,202) test benches::bench_iter_stmts ... bench: 206,687 ns/iter (+/- 35,788) test benches::bench_mask_comments ... bench: 30,087 ns/iter (+/- 4,644) test benches::bench_mask_sub_scopes ... bench: 127,966 ns/iter (+/- 23,547)
