comment-parser

This crate implements a (pull) parser for extracting comments from code in various programming languages.

Usage

Add this to your Cargo.toml:

toml [dependencies] comment-parser = "0.1"

Extract Comments from Rust Code

```rust use comment_parser::CommentParser;

let rust = r#" /* This is the main function */ fn main() { // println! is a macro println!("Hello World"); // Prints "Hello World" } "#;

let rules = commentparser::getsyntax("rust").unwrap();

let parser = CommentParser::new(rust, rules);

for comment in parser { println!("{:?}", comment); } ```

This will output the following:

text BlockComment(_, " This is\nthe main\nfunction ") LineComment(_, " println! is a macro") LineComment(_, " Prints \"Hello World\"")

Extract Comments from Python Code

```rust use comment_parser::CommentParser;

let python = r#"

In Python main is not a function

if name == "main": # print is a function print("Hello World") # Prints "Hello World" "#;

let rules = commentparser::getsyntax("python").unwrap();

let parser = CommentParser::new(python, rules);

for comment in parser { println!("{:?}", comment); } ```

This will output the following:

text LineComment(_, " In Python main is not a function") LineComment(_, " print is a function") LineComment(_, " Prints \"Hello World\"")
