atom-racer's Introduction

Racer

Providing intelligent code completion and "find definition" for Rust via Racer.

Installation

Ensure you have the Atom package language-rust installed and active.
Ensure you have Racer properly installed.
Ensure you have a copy of the rustc source code extracted on your disk.
Install this package via Atom's package manager:

go to Preferences > Packages, search for racer, and install it
OR use the command line apm install racer).

Configuration

go to Preferences > Packages, search for racer, and click Settings

Display Name	Description	Required	Name
Path to the Racer executable	Full path (including executable) of Racer's binary (e.g. `/Users/me/racer/bin/racer` or `c:\racer\bin\racer.exe`)	`YES`	`racer.racerBinPath`
Path to the Rust source code directory	Should point to the rustc source directory (e.g. `/Users/me/code/rust/src/`)	`YES`	`racer.rustSrcPath`
Autocomplete Scope Blacklist	Scopes for which no suggestions will be made (e.g. `.source.go .comment`)	`NO`	`racer.autocompleteBlacklist`
Show position for editor with definition	Can be `Right` or `New`. If `Right` is selected and your view is vertically split, the item will be open in the rightmost pane of the current active pane's row.	`NO`	`racer.show`

Usage

Just type some code in a .rs file, and racer will automatically show you some suggestions (using the autocomplete+ package provided by Atom).

You can also find definition of your current element by pushing the F3 key.

FAQ:

Racer doesn't work, or I see plugin errors when I type:

Your configuration is probably wrong:

The path to Racer has to point to the Racer binary executable (this is NOT a directory we request here).
The Rustc source has to point to the base directory of the source code.
The Atom package language-rust is installed and active.

My project tree (tree-view) flickers:

We use temporary files to communicate with racer and need to place them along with your source files.

We shaped them as ._racertmpXXXXX because the ._* files are ignored by default by Atom.

Change your configuration so that the tree-view package follows Atom ignore rules!

Open Settings > Packages
Search the core package called tree-view, click Settings
Check the box called Hide Ignored Names

Note: by the way, you can control what is ignored in the main Atom settings top panel.

Open Settings > Settings (the first tab)
Search the "core settings" section for the Ignored Names field
check that it's either empty (default), or contains ._*, or add yourself a ._racertmp* entry if you already changed the settings.

Why do you constantly put (and remove) temporary files in my project:

We use temporary files to communicate with racer and need to place them along with your source files so that racer:

locates your project,
provides completion for your whole projects code,
locates your cargo file if it exists and use it to provide completion for your dependencies.

atom-racer's Issues

Not sure what the issue is, but no completion behaviour is observed on my machine. I'm running the latest build of Atom on a Ubuntu 14.04 machine. I'm reasonably sure that things are correctly set up.

Failed to activate package named 'racer'

This comes twice in the developer console on Atom 0.165.0 with Autocomplete-Plus 1.0.0 (which moved to http://www.github.com/atom-community/autocomplete-plus) and Atom-Racer 0.7.1 installed; I even uninstalled all other packages that could somehow interfere, but no luck :-(

Any ideas? Thanks!

Method completion not working?

I'm not entirely sure what this type of completion is called, however it doesn't seem to be working (does racer even support it?).

Here's the code I'm using:

fn main() {
  let a: [i32, 3] = [1, 2, 3];

  println!("Length: {}", a.len());
}

If I delete .len() from the println! and type a dot, I'd expect the completion to list all of the methods I can call on the array, however nothing happens.

I can confirm the package is working to some extent, as completion for things like std::[anything] works.

Here are the versions of rustc, cargo and racer I am running:

rustc 1.8.0-beta.2 (2879d940a 2016-03-22)
cargo 0.9.0-nightly (8fc3fd8 2016-02-29)
racer 1.2.6

racer:
  racerBinPath: "/Users/jack/.cargo/bin/racer"
  rustSrcPath: "/Users/jack/.rust/src/beta/src"

There's no errors in the developer console or anywhere else I can find.

racer returned a non-zero exit code: 1 null

Path to the Racer executable is /home/amos/custom/racer/target/release/racer. It looks right to me:

➜  rust git:(master) which racer
/home/amos/custom/racer/target/release/racer

Path to the Rust source code directory is /home/amos/custom/rust. Also looks right to me:

➜  rust git:(master) pwd
/home/amos/custom/rust
➜  rust git:(master) ls
AUTHORS.txt      COPYRIGHT       LICENSE-MIT  README.md

CONTRIBUTING.md  LICENSE-APACHE  mk           x86_64-unknown-linux-gnu

language-rust is installed.

Do you recognize this error message, or is it a bug with racer? If so, how can I get more information so I can file it with the racer folks?

"Racer returned a non-zero exit status" doesn't show racer failure message

I keep getting "Racer returned a non-zero exit status: 1" messages. Obviously, the problem is my Racer install, not this plugin, but Racer works fine from the command line. Since this message doesn't display the message Racer failed with, it's difficult to figure out what's going on. Is there a way to get Racer failure messages out of the plugin?

No settings option for package

I installed the package, and according to the installation guidelines, I should now go to Packages, look for Racer and click Settings. Racer doesn't have a settings button. Some other packages do, some don't. Racer for sure doesn't.

How to suggest third-party crate's functions?

I noticed that racer only suggest the standard lib's functions. How can I know the functions of third-party lib by using racer instead of referring it's documentation

Racer works from cli but not in atom

using rustup
installed racer with cargo install racer
apm install language-rust linter-rust racer

I added my rust src path and the path to cargo in the racer settings.
path to racer executable: /home/leshow/.cargo/bin/racer
path to rust source code directory: /home/leshow/Development/rust/rust/src/

when I start to type
use std::io::B nothing happens, a hidden file seems to flash in the file tree to the left but I get no completions. If i mess up the rust src path then I get error outputs, but with everything configured correctly I get nothing.

however it works from the cli

> racer complete std::io::B
MATCH BufReader,48,11,/home/leshow/Development/rust/rust/src/libstd/io/buffered.rs,Struct,pub struct BufReader<R>
MATCH BufWriter,300,11,/home/leshow/Development/rust/rust/src/libstd/io/buffered.rs,Struct,pub struct BufWriter<W: Write>
MATCH BufRead,1199,10,/home/leshow/Development/rust/rust/src/libstd/io/mod.rs,Trait,pub trait BufRead: Read
MATCH Bytes,1544,11,/home/leshow/Development/rust/rust/src/libstd/io/mod.rs,Struct,pub struct Bytes<R>

The newest version will appear some tmp file when edit files.

I think it is not a good user experience. Blink files will move our attention. But the old version don't has this problem.

Keep an eye on changes to autocomplete

@alkama I don't know if you are watching this thread but especially since you mentioned a synchronous re-write, I thought I'd point you at it. I also thought you might have some insights to offer in that thread.

Support daemon mode

Racer now has a daemon mode which, as of 1.1.0, has some progress towards caching syntax completion information. It is started with the daemon command and receives the usual commands through stdin.

by default do not pass a rust source

This way the racer default can be used.

It would make it work out of box on rustup setups.

Project.getPath is deprecated.

Use ::getPaths instead

Project.getPath (C:\Users\Jerom\AppData\Local\atom\app-0.190.0\resources\app\src\project.js:585:12)
RacerClient.process_env_vars (C:\Users\Jerom\.atom\packages\racer\lib\racer-client.coffee:48:50)

Flicker in atom file browser due to racer temp file

This might not be something that you can take care of on your end, but it seems that Racer is rapidly creating/deleting a temp file in the working directory when doing autocomplete.

This results in the file browser pane in atom flickering (as the temp file rapidly appears and disappears) every time I type.

Here is a pic showing the temp file in the file browser http://i.imgur.com/3v6rV7v.png

Path to other source code directory?

How can I add multiple sources? For example if I want to have code completion on my own crates?

Failed to activate package named 'racer' RangeError: Maximum call stack size exceeded

Hi..I install the packages using the package manager, but I open the console and get this

Failed to activate package named 'racer' RangeError: Maximum call stack size exceeded

the problem seems this method in underscore

     _.isObject = function(obj) {
        return obj === Object(obj);

I don't know if this can help...

I needed remove the package using apm because this affect all my others packages and made the editor very inestable...

the stacktracer is pretty long and I cant found where start inside the racer package, please let me know if you can solve

atom-racer stopped to work

~~Recently the auto completion of atom-racer is totally broken. The plugin simply stopped working, and also does not provide any error message.~~

Sorry for reporting. The bug was caused by a broken file system. I discovered it just a minute after reporting the bug.

Don't default to hardcoded absolute paths

Since the dawn of time Unix supported searching for binary in $PATH. Please just use racer as the default value for the utility instead of /usr/local/bin/racer which is still worse than the standard /usr/bin/racer.

Also maybe also use /usr/src/rust/src? Any official package, when provided by a Linux distro, would use this path anyway.

Thanks!

Can't get this working

Hi, think I have everything set up correctly, but I can't get anything to autocomplete.

Racer works fine from the CLI, I've set the paths up in the config, and I have language-rust installed. Not sure where I'm going wrong.

Code completion works, but not navigation!

Hi, I am on arch linux, running latest version of atom from git. I installed necessary plugins and code completions works perfectly. But not code navigation. "Go to definition" does nothing.

Please provide suggestions to debug the issue.

[feature request] Symbol fuzzy find

Would it be possible to add support to search through the project's symbols (e.g. function/struct definitions) using the fuzzy finder? You can already jump to a definition of a symbol by placing the cursor on it and pressing the jump to symbol shortcut key, but it would be very handy to be able to just type the name of the struct/function/whatever you want to jump to and go there. This is a common feature in IDEs.

Racer doesn't seem to autocomplete

seems to not return anything. I just built rust off of master set the RUST_SRC_PATH to it, and

completion after semicolon

While typing code, after the last ; (semicolon) a new completion shows up (first entry Trait AsMut), which is undesired.

Atom: v1.12.0-dev-44c0fe5

// e.g.
let mut t = String::new();

Consider adding case insensitive completion

Not sure Racer allows that, but it would be pretty cool to have suggestions pop up even if the typed case was wrong (std::char::tolo and std::char::ToLo should both lead to std::char::ToLowerCase).

"Racer returned a non-zero exit code" 1 null

I ran into the same problem as described in this issue #48. I have all pereferences configured right (racerBinPath=C:\Users\Zhukovskiy.cargo\bin\racer.exe, rustSrcPath=C:\Users\Zhukovskiy\Documents\rustc-beta but I get "keyword autocomplete" only from 'language-rust' plugin. I cannot figure out what's going on. I use v1.5beta right now.

find-definition does not work in read-only projects like rust-source

find-definiton works fine in my projects even on std-library use std::collections::HashMap; - it jumps directly into my rust-source at /usr/local/src/rust/src/. However this is readonly - and I would like to keep it that way.

If I want to explore rust-source by use of find-definition it does not work unless I make it writable for my current user.

I understand that racer needs to have some temporary files. But shouldn't it be possible to explore read-only repositories? I think racer could use a standard-temporary directory like /var or /tmp in that case (or even in general).

What do you think?

Uncaught TypeError: Bad argument

Package installs correct but when I start typing it throws errors in the dev console for nearly every character I type.
System is Fedora 20 with Atom 0.125.0.
Dev Console shows:

A symlink at /usr/local/bin/racer that points to wherever your racer binary is does not work.

Hmm, I was wondering why everything appeared to work from the command line but not in Atom. I was also wondering why I remember it working before whatever I was doing now. Apparently, I had copied the binary, not a symlink in this newer installation I've done.

Anyway, a symlink at /usr/local/bin/racer that points to wherever the racer binary may be placed after compilation doesn't appear to work. My coffeescript skills are non-existent but I bet it has something to do with this.

Error with atom-racer

I get the following message when using atom-racer on Centos/RHEL 7

racer returned a non-zero exit code: 1 /home/darius/Projects/Software/racer/target/release/racer: /lib64/libc.so.6: version 'GLIBC_2.18' not found (required by /home/darius/Projects/Software/racer/target/release/racer)

I do know EL7 has glibc 2.17 but when using Emacs with racer, I do not get an error when using it as well as via terminal which makes me believe something is going on with atom-racer. I could be wrong but I only get this with atom, and nothing else.

Is atom-racer bad for SSDs?

We use temporary files to communicate with racer and need to place them along with your source files.
We shaped them as .racertmpXXXXX because the .* files are ignored by default by Atom.

As I understand, atom-tracer writes a file every time it requests a completion, then deletes it. Doesn't this constant writing/deleting has significant inpact on SSD health?

Racer isnt working

After several attempts, I couldnt get atom-racer working with atom. I reinstalled it, relocated racer and rust source but there is no completion, nor any sign of it being operational. Any clue as to why?

to my keymap.cson file. The "find-definition" function can work well by F1 key. I think F3 is good key for "find-definition". Because the Eclipse also use this key. So how can I use F3 for "find-definition" on my Atom.

Looks like this might actually be a problem with a dependency, runas.

External crates

atom-racer is working great for completions from std and the current file in a project but it does not show completions from external crates and other files in the current project. I was under the impression that racer supported external crates, reading dependencies from Cargo.toml files, and detecting the .cargo folder. Should these features work in atom-racer? Am I doing something wrong?

autocomplete std macros?

A new feature idea :-)

support for autocompletion of (std) macros http://doc.rust-lang.org/std/#macros
support for find-definition of (std) macros?

Uncaught Error: spawn ENOTDIR

[Enter steps to reproduce below:]

i installed the racer package (racer-git from AUR)
I have the rust-nightly-bin package, which I don't believe includes a copy of the src so I cloned rust-lang and pointed racer to the src directory from the rust-lang repo

Can't seem to get the autocomplete to work.

Snippets not supported / strange characters in completion for generics

If I try to complete something like Mutex::new, I get Mutex::new(${1:t: T}) inserted in the editor. This is with atom-racer 0.18.0 and racer 1.2.6.

Integrate racer's find-definition functionality

@edubkendo thanks for your work in integrating racer in Atom. I am using atom-racer for completion but I am relying on ctags to and the Atom symbols-view package in order to go to the definition of a given rust function/type. My hunch is that racer has a better Rust parser and it is also providing a find-definition. Here is the vim integration
https://github.com/phildawes/racer/blob/master/editors/racer.vim#L99

Would it make sense to integrate find-definition directly into atom-racer? If so what are next steps I could help with? I have written node code but I have no experience with Atom.

find-definition silently fails; sometimes briefly creating a new tab

About my environment:

I seem to have atom-racer configured properly, inasmuch as intelligent code completion in atom works quite well.
I'm using Windows 10, rustup-installed stable rust, msvc toolchain.

However, when I use find-definition, there are two different behaviors. Note that I'm using the command palette to launch the Racer: Find Definition command.

if the symbol I'm trying to find the definition of is defined in a separate file (like a method on a struct), nothing visibly happens, not even an error.
if the symbol is in the same file, it looks like it very very briefly opens up a new tab. I think the name of the tab starts with something like ._main.rs.racertmp, followed by a bunch of numbers, and the file I'm currently working in is named main.rs. It disappears very quickly.

Not working on Windows 8.1x64

Because I use a similar Rust Sublime-plugin I've tried to use this one to see if I could replace Sublime completely with Atom 😄

My Racer is installed under c:\bin\racer\racer.exe and the Rust sources are located under a separate disk: d:\src\rust\rust-master\src

Also I've executed "apm install racer" directly after the plugin installation.

However, neither the code completion nor F3 seem to be working at all.

There are no other active plugins because I wanted to use Atom for Rust only.

Updating to “[email protected]” failed.
