Racer-plus

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

Installation

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

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

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)	NO	racer.racerBinPath
Path to the Rust source code directory	Should point to the rustc source directory (e.g. /Users/me/code/rust/src/)	NO	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.
