cargo release

This a script standardize release process of cargo project for you.

Basically it runs following tasks:

• Check if current working directory is git clean
• Read version from Cargo.toml, remove pre-release extension, bump version and commit if necessary
• Run cargo publish (if not disabled)
• Generate rustdoc and push to gh-pages optionally
• Create a git tag for this version
• Bump version for next development cycle
• git push

Install

Current release: 0.9.0

cargo install cargo-release

Usage

cargo release

Prerequisite

• Your project should be managed by git.

Release level

Use -l [level] or --level [level] to specify a release level.

• By default, cargo release removes pre-release extension; if there is no pre-release extension, the current version will be used (0.1.0-pre -> 0.1.0, 0.1.0 -> 0.1.0)
• If level is patch and current version is a pre-release, it behaves like default; if current version has no extension, it bumps patch version (0.1.0 -> 0.1.1)
• If level is minor, it bumps minor version (0.1.0-pre -> 0.2.0)
• If level is major, it bumps major version (0.1.0-pre -> 1.0.0)

From 0.7, you can also use alpha, beta and rc for level. It adds pre-release to your version. You can have multiple alpha version as it goes to alpha.1, alpha.2…

Releasing alpha version on top of a beta or rc version is not allowed and will be resulted in error. So does beta on rc. It is recommended to use --dry-run if you are not sure about the behavior of specific level.

Signing your git commit and tag

Use --sign option to GPG sign your release commits and tags. Further information

Upload rust doc to github pages

By using --upload-doc option, cargo-release will generate rustdoc during release process, and commit the doc directory to gh-pages branch. So you can access your rust doc at https://YOUR-GITHUB-USERNAME.github.io/YOUR-REPOSITORY-NAME/YOUR-CRATE-NAME

If your hosting service uses different branch for pages, you can use --doc-branch to customize the branch we push docs to.

WARNING

This option will override your existed doc branch, use it at your own risk.

Tag prefix

For single-crate repository, we will use version number as git tag name.

For multi-crate repository, the subdirectory name will be used as tag name. For example, when releasing serde_macros 0.7.0 in serde-rs/serde repo, a tag named as serde_macros-0.7.0 will be created.

You can always override this behavior by using --tag-prefix <prefix> option.

Custom remote to push

In case your origin is not writable, you can specify custom remote by --push-remote to set the remote to push.

Use --skip-push if you do not plan to push to anywhere for now.

Specifying dev pre-release extension

After release, the version in Cargo.toml will be incremented and have a pre-release extension added, defaulting to alpha.0.

You can specify a different extension by using the --dev-version-ext <ext> option. To disable version bump after release, use --no-dev-version option.

Update version in README or other files

Cargo-release 0.8 allows you to search and replace version string in any project or source file. See pre-release-replacements in Cargo.toml configuration below.

Pre-release hook

Since 0.9, you can configure pre-release-hook command in Cargo.toml, for example:

pre-release-hook = ["echo", "ok"]

If the return code of hook command is greater than 0, the release process will be aborted.

Configuration in Cargo.toml

From 0.6 you can persist options above in Cargo.toml. We use a custom section called package.metadata.release in Cargo.toml to store these options. Available keys:

• sign-commit: bool, use GPG to sign git commits and tag generated by cargo-release
• upload-doc: bool, generate doc and push to remote branch
• doc-branch: string, default branch to push docs
• push-remote: string, default git remote to push
• disable-push: bool, don't do git push
• dev-version-ext: string, pre-release extension to use on the next development version.
• pre-release-commit-message: string, a commit message template for release. For example: "release {{version}}", where {{version}} will be replaced by actual version.
• pro-release-commit-message: string, a commit message template for bumping version after release. For example: starting next iteration {{version}}, where {{version}} will be replaced by actual version.
• tag-message: string, a message template for tag. Available variables: {{version}}, {{prefix}} (the tag prefix)
• tag-prefix: string, prefix of git tag, note that this will override default prefix based on sub-directory.
• doc-commit-message: string, a commit message template for doc import.
• no-dev-version: bool, disable version bump after release.
• pre-release-replacements: array of tables, specify files that cargo-release will search and replace with new version, check Cargo.toml for example. The table contains three keys:
  • file: the file to search and replace
  • search: regex that matches string you want to replace
  • replace: the replacement, use {{version}} for current version
• pre-release-hook: provide a command to run before cargo-release commits version change

[package.metadata.release]
sign-commit = true
upload-doc = true
pre-release-commit-message = "Release {{version}} 🎉🎉"
pre-release-replacements = [ {file="README.md", search="Current release: [a-z0-9\\.-]+", replace="Current release: {{version}}"} , {file ="Cargo.toml", search="branch=\"[a-z0-9\\.-]+\"", replace="branch=\"{{version}}\""} ]

Dry run

Always call cargo release --dry-run with your custom options before actually executing it. The dry-run mode will print all commands to execute during the release process. And you will get an overview of what's going on.

Here is an example.

 $ cargo release --dry-run
cd .
git commit -S -am (cargo-release) version 0.18.3
cd -
cargo publish
Building and exporting docs.
cargo doc --no-deps
cd target/doc/
git init
cd -
cd target/doc/
git add .
cd -
cd target/doc/
git commit -S -am (cargo-release) generate docs
cd -
cd target/doc/
git push -f [email protected]:sunng87/handlebars-rust.git master:gh-pages
cd -
git tag -a 0.18.3 -m (cargo-release)  version 0.18.3 -s
Starting next development iteration 0.18.4-pre
cd .
git commit -S -am (cargo-release) start next development iteration 0.18.4-pre
cd -
git push origin --follow-tags
