Racer
Providing intelligent code completion and "find definition" for Rust via Racer.
Note: This is a fork of Ebudenko's racer plugin. His repo was unmaintained, and I merged some pull requests that I wanted into my fork.
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 forracer, and install it -
OR use the command line

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.
