Hacking

The following is a quickstart guide for developing cheat.

1. Install system dependencies

Before you begin, you must install a handful of system dependencies. The following are required, and must be available on your PATH:

• git
• go (>= 1.17 is recommended)
• make

The following dependencies are optional:

• docker
• pandoc (necessary to generate a man page)

2. Install utility applications

Run make setup to install scc and revive, which are used by various make targets.

3. Development workflow

After your environment has been configured, your development workflow will resemble the following:

1. Make changes to the cheat source code.
2. Run make test to run unit-tests.
3. Fix compiler errors and failing tests as necessary.
4. Run make. A cheat executable will be written to the dist directory.
5. Use the new executable by running dist/cheat <command>.
6. Run make install to install cheat to your PATH.
7. Run make build-release to build cross-platform binaries in dist.
8. Run make clean to clean the dist directory when desired.

You may run make help to see a list of available make commands.

Developing with docker

It may be useful to test your changes within a pristine environment. An Alpine-based docker container has been provided for that purpose.

If you would like to build the docker container, run:

make docker-setup

To shell into the container, run:

make docker-sh

The cheat source code will be mounted at /app within the container.

If you would like to destroy this container, you may run:

make distclean
