C source lexer in Rust

This is a fast and robust C source lexer in Rust. For example it can be used to extract some metadata from sources like comments or strings.

Library usage

```rust use clex::{Lexer, Token};

let src = r#" static const char *s = "world";

int main() { // Hello world printf("Hello %s\n", s);

return 0; } "#;

for lexeme in Lexer::from(src) { match lexeme.token { Token::Comment => { println!("comment: {:?}", lexeme.comment().unwrap()); } Token::String => { println!("string: {:?}", lexeme.string().unwrap()); } _ => {} } } ```

This example prints the following:

text string: "world" comment: "Hello world" string: "Hello %s\n"

Command-line usage

Currently command-line tool is used to test this library. You can use it to analyze variuos C-sources and extract data.
