Developer Setup

As a CCCL developer, there are many routine setup tasks that need to be done after cloning a repo. While our devcontainers streamline much of the process, there are still setup tasks that need to be done on the host-side repo that cannot be configured via devcontainers:

• remote fork setup
• git repo config (rev-parse-ignore, git aliases, ignore copy-pr-bot branches on fetch)
• host-side vscode extension setup
• host-side precommit install
• WSL setup / error checking

Developer One-Shot

As a CCCL developer, I need to fetch/build/test a single SHA on a remote / temporary environment.

• Single-branch shallow fetch
• Option to run arbitrary commands in the fetched repo to simplify scripting
  • Examples of useful commands: ci/{build,test}_*.sh, ci/util/build_and_test_targets.sh .devcontainer/launch.sh -d <...>

User Clone / Install

As a CCCL user, I'd like to be able to do a minimum fetch/install of a user-facing branch:

• Single branch clone
• Shallow clone
• Restrict auto-fetch branches to only main and release branches.
• (optional: --install <path>) Minimum config/build/install cycle restricted to only producing an install tree.

Describe the solution you'd like

Add convenience scripts that can be wget | bash'd to implement the above workflows:

• setup/dev_clone.sh
  • clones and calls dev_setup.sh to do the bulk of the work (allows post-clone setup on existing repos).
• setup/oneshot_clone.sh
• setup/user_clone.sh
  • Install option uses existing install scripts.
