Example

Here is an example for building a project in a mono-repo.

#
# my-project/.run-tool.yml
#

targets:
  clean-build:
    program: cargo
    args:
      - build
      - --release
    env:
        CARGO_HOME: /mnt/cache/.cargo
    cwd: backend/
    before_hooks:
      - clean

  clean:
    program: cargo
    args:
      - clean
    cwd: backend/
