AsciiMath

This project aims to implement a fully functional AsciiMath parser for rust. It's part of the snekdown parser project.

See the spec.

Dependencies

• charred used by the tokenizer to analyze the input string
• maplit for an easy to use macro to define the token mappings
• lazy_static to define static mappings for tokens
• htmlescape for escaping html when converting to mathml

Usage

The simple way

```rust use asciimath_rs::format::mathml::ToMathML;

fn main() { let expression = asciimathrs::parse("sin(2x) + 3".tostring()); let mathmlstring = expression.tomathml(); } ```

The less simple way

```rust use asciimathrs::parsing::tokenizer::Tokenizer; use asciimathrs::parsing::treeparser::TreeParser; use asciimathrs::format::mathml::ToMathML;

fn main() { let mut tokenizer = Tokenizer::new("cos(2) - alpha".tostring()); let tokens = tokenizer.parse(); let mut treeparser = TreeParser::new(tokens); let expression = treeparser.parse(); let mathmlstring = expression.to_mathml(); } ```

How it works

As seen in the less simple example the parsing works in two steps. In the first step the raw input string is analyzed and converted into Tokens that represent the syntactic meaning of a sequence of characters. The second step takes the flat vector of tokens and converts it into a tree in a depth first way.

The resulting expression can then be converted into MathML with the default ToMathML trait implementation.
