cargo.el

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

NOTICE

Currently I'm not using Rust, nor will I in the (near) future. I've lost track of all the Rust / Cargo features available and can't keep up-to-date with new ones. I'll be doing selective bug fixes and continue reviewing / merging pull requests.

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
C-c C-c C-a	cargo-process-add
C-c C-c C-S-d	cargo-process-rm
C-c C-c C-S-u	cargo-process-upgrade
C-c C-c C-S-a	cargo-process-audit
C-c C-c C-S-r	cargo-process-script
C-c C-c C-w	cargo-process-watch
C-c C-c C-S-f	cargo-find-dependency

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.

To change prefix (default C-c C-c) use:

 (define-key cargo-mode-map (kbd ...) 'cargo-minor-mode-command-map)

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 "bench")
(setq cargo-process--command-build "build")
(setq cargo-process--command-clean "clean")
(setq cargo-process--command-doc "doc")
(setq cargo-process--command-doc-open "doc --open")
(setq cargo-process--command-new "new")
(setq cargo-process--command-init "init")
(setq cargo-process--command-run "run")
(setq cargo-process--command-run-bin "run --bin")
(setq cargo-process--command-run-example "run --example")
(setq cargo-process--command-search "search")
(setq cargo-process--command-test "test")
(setq cargo-process--command-current-test "test")
(setq cargo-process--command-current-file-tests "test")
(setq cargo-process--command-update "update")
(setq cargo-process--command-fmt "fmt")
(setq cargo-process--command-check "check")
(setq cargo-process--command-clippy "clippy")
(setq cargo-process--command-add "add")
(setq cargo-process--command-rm "rm")
(setq cargo-process--command-upgrade "upgrade")
(setq cargo-process--command-audit "audit -f")
(setq cargo-process--command-script "script")
(setq cargo-process--command-watch "watch -x build")

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. By default, in compilation mode, C-c C-k is bound to the command kill-compilation.
