Aspect Bazel Starter for Ruby

This repository uses Aspect Workflows to provide an excellent Bazel developer experience. It was generated from the Aspect Workflows template — create your own with aspect init (see https://aspect.build/docs/cli) or from a starter at https://github.com/aspect-starters.

Getting started

1. Install the Aspect CLI — see https://aspect.build/docs/cli/install. The aspect command pins this workspace's CLI version (via .aspect/version.axl) and wraps Bazel, so use it in place of bazel.

2. Set up a Bazel-based developer environment with direnv: run direnv allow and follow the prompts to bazel run //tools:bazel_env (puts the project's tools — including aspect itself — on your PATH, so an aspect installed in step 1 isn't required once direnv is active).

3. Build and test everything:

   aspect build //...
   aspect test //...

   A small hello/ sample is included for each selected language as a starting point.

Formatting code

format is put on your PATH by bazel_env (via .envrc).

• Run format to re-format all files locally.
• Run format path/to/file to re-format a single file.
• On CI, run the format task to verify formatting; see https://aspect.build/docs/cli/tasks-ci

Linting code

This project uses rules_lint to run linters as Bazel aspects. The linters are configured in .aspect/config.axl and run via the Aspect CLI's lint command (not the upstream Bazel CLI), which collects the cached report files, applies fixes interactively, and sets a matching exit code.

• Run aspect lint //... to check for lint violations.

Installing dev tools

For developers to be able to run additional CLI tools without needing manual installation:

1. Add the tool to tools/tools.lock.json
2. Run bazel run //tools:bazel_env (following any instructions it prints)
3. When working within the workspace, tools will be available on the PATH
