A tooling and language agnostic utility to lint Git commits against the Conventional Commits specification.
Conventional Commits Linter can either operate upon a range of Git commits in the repositories' history or on a commit message from standard in.
To provide a commit message by standard in simple add the flag --from-stdin and standard in will be read.
Otherwise to specify the range of commits you can add either the --from-commit-hash <commit-hash> or --from-reference <reference> arguments.
The range of commits starts exclusively from the commit specified till inclusively of HEAD.
All commit messages provided or within the range are linted against the Conventional Commits v1.0.0 specification. If any commits messages fail linting then an error message explaining why is logged and Conventional Commits Linter exits with a non zero exit code.
The only required arguments are any of the --from-stdin, --from-commit-hash <commit-hash> or --from-reference <reference> arguments.
| Flag | |
|---------------------------|-|
| --allow-angular-type-only | Allow the Conventional Commits type to only be (build, ci, docs, feat, fix, perf, refactor, style, test, revert), otherwise linting for the commit will fail. |
| --output | How to output the linting results if their are any, the options are (Quiet, Pretty, JSON) Pretty is the default. |
When looking for a repository the Git environment variables are respected.
When ${GIT_DIR} is set, it takes precedence and Conventional Commits Linter begins searching for a repository in the directory specified in ${GIT_DIR}.
When ${GIT_DIR} is not set, Conventional Commits Linter searches for a repository beginning in the current directory.
The crates pretty_env_logger and log are used to provide logging.
The environment variable RUST_LOG can be used to set the logging level.
See https://crates.io/crates/prettyenvlogger for more detailed documentation.
See Compiling via Cargo for more details about installing via Cargo.
Note - This example downloads the latest 0.* version.

An example commit-msg Git hook to check if a Rust projects semantic version needs increased because of the commit message.
```sh
set -o errexit set -o pipefail
cat "${1}" | "${HOME}/.cargo/bin/conventionalcommitslinter" --from-stdin --allow-angular-type-only ```
Statically linked compiled binaries are available for download. Visit the releases page at https://gitlab.com/DeveloperC/conventionalcommitslinter/-/releases to see all the releases, the release notes contains links to binary downloads for various architectures.
If you do not trust the provided binaries another option is to compile your own and then make it available for remote download, so your CICD etc can then download it.
Checkout the code repository locally, change into the repository's directory and then build via cargo.
Using the --release flag produces an optimised binary but takes longer to compile.
sh
git clone git@gitlab.com:DeveloperC/conventional_commits_linter.git
cd conventional_commits_linter/
cargo build --release
The compiled binary is present in target/release/conventional_commits_linter.
Cargo is the Rust package manager, using the install sub-command it pulls the Conventional Commits Linter from crates.io and then compiles the binary locally.
cargo install places the produced binary at ${HOME}/.cargo/bin/conventional_commits_linter.
sh
cargo install conventional_commits_linter
By default it installs the latest version at the time of execution.
You can specify a specific version to install using the --version argument.
For certain environments such as CICD etc you may want to pin the version.
e.g.
sh
cargo install conventional_commits_linter --version 0.12.0
Rather than pinning to a specific version you can specify the major or minor version.
e.g.
sh
cargo install conventional_commits_linter --version ^0
Will download the latest 0.* release whether that is 0.12.0 or 0.23.0.
The unit test suite has a number parameterised tests testing the Conventional Commits v1.0.0 linting, cargo can be used to setup and run all the unit tests.
sh
cargo test
To ensure correctness as there are a variety of out of process dependencies the project has an End-to-End behaviour driven test suite using the behave framework (https://github.com/behave/behave).
To run the test suite you need to - Compile the Convention Commits Linter binary. - Install Python3. - Install Behave. - Execute Behave.
Note - You can't use --release as the test suite uses target/debug/conventional_commits_linter.
sh
cargo build
cd conventional_commits_linter/end-to-end-tests/
virtualenv -p python3 .venv
source .venv/bin/activate
pip3 install -r requirements.txt
behave
