# cargo-semver-checks-action
|
|
Lint your crate API changes for semver violations.
|
|
|
|
By default, this action assumes that:
|
|
- Your cargo workspace contains a single crate which contains a library target.
|
|
- Your releases are tagged in git as `v{major}.{minor}.{patch}`, for example `v1.2.3`.
|
|
|
|
Single-crate workspaces can use it as:
|
|
```yaml
|
|
- name: Check semver
|
|
uses: obi1kenobi/cargo-semver-checks-action@v1
|
|
- name: Publish to crates.io
|
|
run: # your `cargo publish` code here
|
|
```
|
|
|
|
# Input options
|
|
|
|
Every argument is optional.

|--------------------|-----------------------------------------------------------------------------------------------------------------------------------|---------|
|
|
| crate-name | The crate whose API to check for semver (needed only in multi-crate workspaces). | |
|
|
| crate-target | (Deprecated) By default, check the library target of the crate. To check a different target (e.g. a binary target), set this to `--bin <NAME>`. Will be removed in future versions, as bin targets do not have library-like API to check. | `--lib` |
|
|
| version-tag-prefix | The prefix to use for the git tag for a version; the default "v" creates tags like "v1.0.0". | `v` |
|
|
|

# Scenarios
|
|
|
|
- [Use with a different version tag format](#use-with-a-different-version-tag-format)
|
|
- [Use in workspaces with more than one crate](#use-in-workspaces-with-more-than-one-crate)
|
|
- [(Deprecated) Use with binary crates or crates with more than one target](#deprecated-use-with-binary-crates-or-crates-with-more-than-one-target)
|
|
|
|
## Use with a different version tag format
|
|
|
|
Change the `version-tag-prefix` setting to reflect the prefix used to create the version tag. The setting's default value `'v'` creates version tags like `v1.2.3`.
|
|
|
|
For example, if your versions are tagged as `1.2.3`, you can set `version-tag-prefix` to be the empty string:
|
|
```yaml
|
|
- name: Check semver
|
|
uses: obi1kenobi/cargo-semver-checks-action@v1
|
|
with:
|
|
version-tag-prefix: ''
|
|
- name: Publish my-crate to crates.io
|
|
run: # your `cargo publish` code here
|
|
```
|
|
|
|
## Use in workspaces with more than one crate
|
|
|
|
You'll need to specify which crate should be checked, and the format used for version tags for that crate:
|
|
- `crate-name` specifies the crate to check, and
|
|
- `version-tag-prefix` sets the text prepended to the version number to create the git tag for that release.
|
|
|
|
For example, this will check `my-crate` whose releases are tagged as `my-crate-v1.2.3`:
|
|
```yaml
|
|
- name: Check semver
|
|
uses: obi1kenobi/cargo-semver-checks-action@v1
|
|
with:
|
|
crate-name: my-crate
|
|
version-tag-prefix: my-crate-v
|
|
- name: Publish my-crate to crates.io
|
|
run: # your `cargo publish` code here
|
|
```
|
|
|
|
## (Deprecated) Use with binary crates or crates with more than one target
|
|
|
|
To check a different (non-library) target in a crate, use the `crate-target` setting:
|
|
```yaml
|
|
- name: Check semver for my_binary
|
|
uses: obi1kenobi/cargo-semver-checks-action@v1
|
|
with:
|
|
crate-target: --bin my_binary
|
|
- name: Publish my-crate to crates.io
|
|
run: # your `cargo publish` code here
|
|
```
