cargo-workspaces

Inspired by Lerna

A tool that optimizes the workflow around cargo workspaces with git and cargo by providing utilities to version, publish, execute commands and more.

I made this to work on clap and other projects that rely on workspaces. But this will also work on single crates because by default every individual crate is a workspace.

Installation

cargo install cargo-workspaces

Usage

The installed tool can be called by cargo workspaces or cargo ws. Both of them point to the same.

You can use cargo ws help or cargo ws help <subcmd> anytime to understand allowed options.

The basic commands available for this tool are given below. Assuming you run them inside a cargo workspace.

Init

Initializes a new cargo workspace in the given directory. Creates Cargo.toml if it does not exist and fills the members with the all the crates that can be found in that directory.

``` USAGE: cargo workspaces init [path]

ARGS: Path to the workspace root [default: .]

FLAGS: -h, --help Prints help information ```

Create

Interactively creates a new crate in the workspace. We recommend using this instead of cargo new. All the crates start with 0.0.0 version because the version is responsible for determining the version.

``` USAGE: cargo workspaces create

ARGS: Path for the crate relative to the workspace manifest

FLAGS: -h, --help Prints help information ```

List

Lists crates in the workspace.

``` USAGE: cargo workspaces list [FLAGS]

FLAGS: -a, --all Show private crates that are normally hidden -h, --help Prints help information --json Show information as a JSON array -l, --long Show extended information ```

Several aliases are available.

Changed

List crates that have changed since the last git tag. This is useful to see the list of crates that would be the subjects of the next version or publish command.

``` USAGE: cargo workspaces changed [FLAGS] [OPTIONS]

FLAGS: -a, --all Show private crates that are normally hidden -h, --help Prints help information --include-merged-tags Include tags from merged branches --json Show information as a JSON array -l, --long Show extended information

OPTIONS: --force Always include targeted crates matched by glob even when there are no changes --ignore-changes Ignore changes in files matched by glob --since Use this git reference instead of the last tag ```

Exec

Executes an arbitrary command in each crate of the workspace.

``` USAGE: cargo workspaces exec [FLAGS] ...

ARGS: ...

FLAGS: -h, --help Prints help information --no-bail Continue executing command despite non-zero exit in a given crate ```

For example, if you want to run ls -l in each crate, you can simply do cargo ws exec ls -l.

Version

Bump versions of the crates in the worksapce. This command does the following:

  1. Identifies crates that have been updated since the previous tagged release
  2. Prompts for a new version according to the crate
  3. Modifies crate manifest to reflect new release
  4. Update intra-workspace dependency version constraints if needed
  5. Commits those changes
  6. Tags the commit
  7. Pushes to the git remote

You can influence the above steps with the flags and options for this command.

``` USAGE: cargo workspaces version [FLAGS] [OPTIONS] [ARGS]

ARGS: Increment all versions by the given explicit semver keyword while skipping the prompts for them [possible values: major, minor, patch, premajor, preminor, prepatch, prerelease, custom] Specify custom version value when 'bump' is set to 'custom'

FLAGS: -a, --all Also do versioning for private crates (will not be published) --amend Amend the existing commit, instead of generating a new one --exact Specify inter dependency version numbers exactly with = -h, --help Prints help information --include-merged-tags Include tags from merged branches --no-git-commit Do not commit version changes --no-git-push Do not push generated commit and tags to git remote --no-git-tag Do not tag generated commit --no-global-tag Do not create a global tag for a workspace --no-individual-tags Do not tag individual versions for crates -y, --yes Skip confirmation prompt

OPTIONS: --allow-branch Specify which branches to allow from [default: master] --force Always include targeted crates matched by glob even when there are no changes --git-remote Push git changes to the specified remote [default: origin] --ignore-changes Ignore changes in files matched by glob --individual-tag-prefix Customize prefix for individual tags (should contain %n) [default: %n@] -m, --message Use a custom commit message when creating the version commit --pre-id Specify prerelease identifier --tag-prefix Customize tag prefix (can be empty) [default: v] ```

Fixed or Independent

By default, all the crates in the workspace will share a single version. But if you want the crate to have it's version be independent of the other crates, you can add the following to that crate:

toml [package.metadata.workspaces] independent = true

Publish

Publish all the crates from the workspace in the correct order according to the dependencies. By default, this command runs version first. If you do not want that to happen, you can supply the --from-git option.

``` USAGE: cargo workspaces publish [FLAGS] [OPTIONS] [ARGS]

ARGS: Increment all versions by the given explicit semver keyword while skipping the prompts for them [possible values: major, minor, patch, premajor, preminor, prepatch, prerelease, custom] Specify custom version value when 'bump' is set to 'custom'

FLAGS: -a, --all Also do versioning for private crates (will not be published) --amend Amend the existing commit, instead of generating a new one --exact Specify inter dependency version numbers exactly with = --from-git Publish crates from the current commit without versioning -h, --help Prints help information --include-merged-tags Include tags from merged branches --no-git-commit Do not commit version changes --no-git-push Do not push generated commit and tags to git remote --no-git-tag Do not tag generated commit --no-global-tag Do not create a global tag for a workspace --no-individual-tags Do not tag individual versions for crates --no-verify Skip crate verification (not recommended) --skip-published Skip already published crate versions -y, --yes Skip confirmation prompt

OPTIONS: --allow-branch Specify which branches to allow from [default: master] --force Always include targeted crates matched by glob even when there are no changes --git-remote Push git changes to the specified remote [default: origin] --ignore-changes Ignore changes in files matched by glob --individual-tag-prefix Customize prefix for individual tags (should contain %n) [default: %n@] -m, --message Use a custom commit message when creating the version commit --pre-id Specify prerelease identifier --tag-prefix Customize tag prefix (can be empty) [default: v] --token The token to use for publishing ```
