If you want to contribute to the development of rust-code-analysis we have summarized here a series of guidelines that are supposed to help you in your building process.

As prerequisite, you need to install the last available version of Rust. You can learn how to do that here.

First of all, you need to clone the repository. You can do that:

through HTTPS

git clone -j8 https://github.com/mozilla/rust-code-analysis.git

or through SSH

git clone -j8 git@github.com:mozilla/rust-code-analysis.git

To build the rust-code-analysis library, you need to run the following command:

cargo build

If you want to build the cli:

cargo build -p rust-code-analysis-cli

If you want to build the web server:

cargo build -p rust-code-analysis-web

If you want to build everything in one fell swoop:

cargo build --workspace

After you have finished changing the code, you should always verify whether all tests pass with the cargo test command.

cargo test --workspace --all-features --verbose

If all previous steps went well, and you want to make a pull request to integrate your invaluable help in the codebase, the last step left is code formatting.

This tool formats your code according to Rust style guidelines.

To install:

rustup component add rustfmt

To format the code:

cargo fmt

This tool helps developers to write better code catching automatically lots of common mistakes for them. It detects in your code a series of errors and warnings that must be fixed before making a pull request.

To install:

rustup component add clippy

To detect errors and warnings:

cargo clippy --workspace --all-targets --

If you have documented your code, to generate the final documentation, run this command:

cargo doc --open --no-deps

Remove the --no-deps option if you also want to build the documentation of each dependency used by rust-code-analysis.

You can run rust-code-analysis-cli using:

cargo run -p rust-code-analysis-cli -- [rust-code-analysis-cli-parameters]

To know the list of rust-code-analysis-cli parameters, run:

cargo run -p rust-code-analysis-cli -- --help

You can run rust-code-analysis-web using:

cargo run -p rust-code-analysis-web -- [rust-code-analysis-web-parameters]

To know the list of rust-code-analysis-web parameters, run:

cargo run -p rust-code-analysis-web -- --help

• When you add a new feature, add at least one unit or integration test to verify that everything works correctly
• Document public API
• Do not add dead code
• Comment intricate code such that others can comprehend what you have accomplished
