Contributing

Developing

You need Opam, you can install it by following Opam's documentation.

With Opam installed, you can install the dependencies with:

opam install --deps-only --with-test -y .

Then, build the project with:

make

Running Examples

After building the project, you can run the example binaries with:

dune exec examples/<example>.exe

For instance, to run the confirm.ml example, you can type:

dune exec examples/confirm.exe

Running Tests

You can test compiled executable with:

make test

Building documentation

Documentation for the libraries in the project can be generated with:

make doc
open-cli $(make doc-path)

This assumes you have a command like open-cli installed on your system.

Create new releases

To create a release and publish it on Opam, you can run the script scripts/release.sh. It will create a tag with the version found in inquire.opam, and push it on your repository.

From there, the CI/CD will take care of publishing your documentation, create a github release, and open a PR with your version on opam-repository.
