# libvieter

This library powers part of Vieter, most noteably the sections that can easily
be implemented in C (or just parts I want to implement in C because it's fun).

The goal of this library is to be completely self-contained, meaning any
required data structures have to be implemented as well. It can only depend on
the C standard libraries.

Currently it contains the following:

* Cron expression parser & next time calculator

## Development

### Compilation

Everything is handled by the provided Makefile. To compile the static library,
simply run `make`.

### Testing

This library uses [Acutest](https://github.com/mity/acutest) for its tests.
Tests should be placed in the `test` subdirectory, further divided into
directories that correspond those in `src`. Test files should begin with
`test_`, and their format should follow the expected format for Acutest.

To run the tests, simply run `make test`. If you wish to only run a specific
test binary, you can find them in `build/test`.

### `compile_commands.json`

Clangd requires a `compile_commands.json` to function properly. You can
generate it using [bear](https://github.com/rizsotto/Bear):

```sh
make clean
bear -- make
bear --append -- make build-test
```

This will create a `compile_commands.json` file in the current directory.
