Cargo Version Control System extension
Cargo-vcs is a Cargo extension that adds version control helpers to help manage workspace members.
Example use cases
View current branch and MSRV status for workspace members
cargo vcs status- for brief overview
cargo vcs status -v- for verbose view
$ cargo vcs status Workspace is set to profile: new [.../rust/embedded] MSRV: 1.59.0 ** Projects with uncommitted changes ** redv: refs/heads/e-h-1.0.0-alpha.7 [.../rust/embedded/apps/redv] └── [CHANGES] └── src/main.rs e310x-hal: refs/heads/e-h-1.0.0-alpha.7 [.../rust/embedded/e310/e310x-hal] └── [CHANGES] ├── src/spi/bus.rs └── src/spi/config.rs
Switch to a branch or commit on workspace members
cargo vcs checkout master- switch to master on all workspace members
cargo vcs checkout master -m member1, member2- switch on specific members only
$ cargo vcs checkout master redv set to refs/heads/master embedded-hal set to refs/heads/master e310x set to refs/heads/master e310x-hal set to refs/heads/master hifive1 set to refs/heads/master riscv set to refs/heads/master riscv-rt set to refs/heads/master mipidsi set to refs/heads/master
Working with profiles
cargo vcs profile save profile1- saves current repo state of each workspace member under the name
cargo vcs profile set profile1- switches all workspace member repositories to state saved in
$ cargo vcs profile set new redv set to refs/heads/e-h-1.0.0-alpha.7 embedded-hal set to refs/tags/v1.0.0-alpha.7 e310x set to refs/heads/e-h-1.0.0-alpha.7 e310x-hal set to refs/heads/e-h-1.0.0-alpha.7 hifive1 set to refs/heads/v0.11.0-alpha.1 riscv set to refs/heads/e-h-1.0.0-alpha.7 riscv-rt set to refs/heads/e-h-1.0.0-alpha.7 mipidsi set to refs/heads/v0.3.0-alpha.1
Navigating to a specific workspace member
$ cd $(cargo vcs dir member1)
Profile config is saved in the workspace root directory under the name
Cargo_vcs.toml. Manual editing is possible but using
cargo vcs profile save <profile_name> is the preferred method as it resolves shortnames to full repository reference paths.
Toml file with the format of
[vcs.<profile_name>] <project_name> = "<git_reference>" ...
Git is currently the only supported VCS.
Profile and branch switching with uncommitted changes result in new stash pushes. Stashed changes are popped back when returning to the source reference or profile.
Each stash change is saved under a specific name and looked up as such, FIFO is not used and stash changes created outside of cargo-vcs are not considered.
Currently only git is supported. Other version control systems can be added by implementing the
Repository trait, however some more work is required in regards to the dirty changes strategy.
Minimum Supported Rust Version (MSRV)
This crate is guaranteed to compile on stable Rust 1.59.0 and up. It might compile with older versions but that may change in any new patch release.
This project is still in early release phases. It should be safe to use but there's always a possibility of bugs which could result in workspace repositories ending up in an odd state.
