cargo.el

Cargo mode for Emacs. This package gives you a set of key combinations to perform Cargo tasks within your Rust projects.

Installation

This package can be installed through melpa:

M-x package-install cargo

Usage

Add cargo-minor-mode to your rust-mode-hook

(add-hook 'rust-mode-hook 'cargo-minor-mode)

You will now have the following key combinations at your disposal:

Keybinding	Command
C-c C-c C-e	cargo-process-bench
C-c C-c C-b	cargo-process-build
C-c C-c C-l	cargo-process-clean
C-c C-c C-d	cargo-process-doc
C-c C-c C-v	cargo-process-doc-open
C-c C-c C-n	cargo-process-new
C-c C-c C-i	cargo-process-init
C-c C-c C-r	cargo-process-run
C-c C-c C-x	cargo-process-run-example
C-c C-c C-s	cargo-process-search
C-c C-c C-t	cargo-process-test
C-c C-c C-u	cargo-process-update
C-c C-c C-c	cargo-process-repeat
C-c C-c C-f	cargo-process-current-test
C-c C-c C-o	cargo-process-current-file-tests
C-c C-c C-m	cargo-process-fmt
C-c C-c C-k	cargo-process-check
C-c C-c C-S-k	cargo-process-clippy

Before executing the task, Emacs will prompt you to save any modified buffers associated with the current Cargo project. Setting compilation-ask-about-save to nil makes Emacs save modified buffers without asking.

Variables

Commands can be adjusted by changing their command variable. Here's a list of commands and their default value.

(setq cargo-process--command-bench "cargo bench")
(setq cargo-process--command-build "cargo build")
(setq cargo-process--command-clean "cargo clean")
(setq cargo-process--command-doc "cargo doc")
(setq cargo-process--command-doc-open "cargo doc --open")
(setq cargo-process--command-new "cargo new")
(setq cargo-process--command-init "cargo init")
(setq cargo-process--command-run "cargo run")
(setq cargo-process--command-run-bin "cargo run --bin")
(setq cargo-process--command-run-example "cargo run --example")
(setq cargo-process--command-search "cargo search")
(setq cargo-process--command-test "cargo test")
(setq cargo-process--command-current-test "cargo test")
(setq cargo-process--command-current-file-tests "cargo test")
(setq cargo-process--command-update "cargo update")
(setq cargo-process--command-fmt "cargo fmt")
(setq cargo-process--command-check "cargo check")
(setq cargo-process--command-clippy "cargo clippy")

Advanced usage

If you invoke the prefix argument C-u before calling any of the functions, you may edit the Cargo command before it is run. This allows you to add flags like --release, for example.

Processes run via Cargo mode make use of compilation mode. This mode provides features like jumping to errors or killing runaway processes.
