# Lang-C
[](https://travis-ci.com/vickenty/lang-c)
[](https://docs.rs/lang-c)
Ligtweight parser of C language for Rust users. Almost full support for C11 revision of the language.
Several GCC and Clang extensions are also supported as an option.
```rust
extern crate lang_c;
use lang_c::driver::{Config, parse};
fn main() {
let config = Config::default();
println!("{:?}", parse(&config, "example.c"));
}
```

## License

## Development
A number of external tools are used during development:
- GNU make
- rustfmt
- [rust-peg](https://github.com/kevinmehall/rust-peg) 0.5.7
Parser (`src/parser.rs`) is built from a PEG grammar in `grammar.rustpeg`. It is updated manually and then
committed, not generated on every build, thus no `rust-peg` in the list of dependencies.
For debugging purposes, it is handy to have a version rust-peg built with tracing enabled.
A makefile is used to script the development process:
- `make` update parser, build the library and run the tests;
- `make trace` rebuilds parser using `rust-peg-trace`, which is expected to be a version of `rust-peg` command with `trace` feature enabled
- `make check` can be used as pre-commit git hook to make sure parser is up to date
