# libvieter
|
|
|
|
This library powers part of Vieter, most notably 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 as self-contained as possible; data
|
|
structures should be implemented manually if possible.
|
|
|
|
See the [source code](src) for the list of modules.
|
|
|
|
## Development
|
|
|
|
### Compilation
|
|
|
|
Everything is handled by the provided Makefile. To compile the static library,
|
|
simply run `make`.
|
|
|
|
### Required libraries
|
|
|
|
Libvieter requires libarchive.
|
|
|
|
### Project structure
|
|
|
|
Each module has its own subdirectory inside `src`, e.g. `src/cron`. This
|
|
directory contains the actual implementation of a module, along with any
|
|
internally used header files. Each internal function should be defined in a
|
|
header file, as to make testing these possible.
|
|
|
|
Each module should also have its own header file inside the `include`
|
|
directory. This header file defines the public API that the library exposes for
|
|
this specific module.
|
|
|
|
Any code in a module may only import internal headers from that module, along
|
|
with any of the public API header files. Modules should not depend on each
|
|
other's internal implementationns.
|
|
|
|
Each module should contain a README describing its contents.
|
|
|
|
All file names, function names... (even internals) should follow snake case
|
|
convention and have a prefix unique to that module, starting with `vieter_`.
|
|
For example, the `cron` modules uses the `vieter_cron_` prefix for everything.
|
|
|
|
Header files should only import what they explicitely need. If some function is
|
|
only used in a .c file, the import should be placed in the .c file instead.
|
|
|
|
### 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 to those in `src`. Test files should begin with
|
|
`test_`, and their format should follow the expected format for Acutest.
|
|
|
|
Each `test_` is compiled separately into a binary, linked with libvieter. A
|
|
test file can import any of the public API header files, along with any header
|
|
files defined in its respective module. This allows testing internal functions.
|
|
|
|
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.
