BEM Parser
A Rust-based parser for the BEM (Block Element Modifier) file format, utilizing the Pest parsing library.
Overview
This parser provides functionality to parse BEM notations, primarily used in CSS methodologies for naming classes in HTML. With this parser, you can interpret and work with BEM notations programmatically in Rust.
Features
- Parse BEM blocks, elements, and modifiers.
- Support for dashes in block and element names.
- Support for enclosing modifiers in square brackets and separating with commas.
- Robust error handling with detailed parsing error messages.
- Lightweight and efficient parsing using Pest.
Getting Started
Prerequisites
Ensure you have Rust and Cargo installed:
curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh
Usage
Here's a simple example to parse a BEM formatted string:
use bem::parse;
let input = "block[mod1,mod2]\nelement1\nelement2[mod3]";
let bem_block = parse(input).unwrap();
// You can now access `bem_block.name`, `bem_block.modifiers`, and `bem_block.elements`.
Error Handling
The parse
function returns a Result<BEMBlock, String>
, allowing you to handle parsing errors explicitly. Here's an example:
let input = "block[mod1,mod2]\nelement1\nelement2[mod3]";
match parse(input) {
Ok(bem_block) => {
// Process the parsed block
},
Err(error) => {
println!("Failed to parse BEM content: {}", error);
}
}
