latex-math-parser

A parser for LaTeX math expressions.

This parser converts LaTeX math syntax into an abstract syntax tree (AST) representation. It is built using PEG.js and supports a mostly complete set of standard LaTeX math expressions.

Installation

bash npm install @andstor/latex-math-parser

Usage

```js const { parse } = require('@andstor/latex-math-parser');

const latex = '\frac{a}{b} + \sqrt{x}'; const ast = parse(latex);

console.log(JSON.stringify(ast, null, 2)); ```

Generators

This parser can be used with various code generators to convert the AST into different programming languages or formats. Currently supported generators include: - maxima-codegen: Maxima is a computer algebra system that can manipulate symbolic expressions.

Features

The complete grammar for this parser can be found at src/grammars/latex.pegjs. Following are some of the key features supported by the parser:

  • Arithmetic operations: Addition, subtraction, multiplication, division, modulo, exponentiation, and implied multiplication.
  • Logical and bitwise operations: Logical AND/OR, bitwise AND/OR/XOR, relational and equality operators.
  • Assignment expressions: Standard and compound assignments (e.g., =, +=, *=, etc.).
  • Function calls: Built-in and user-defined functions, including support for argument lists and nested calls.
  • Fractions: Parsing of LaTeX \frac expressions.
  • Limits: Parsing of limit expressions (e.g., \lim).
  • Logarithms: Parsing of logarithms with arbitrary bases, including \log, \ln, and \lg.
  • Binomial coefficients: Parsing of \binom.
  • Summations: Parsing of \sum with lower and upper bounds.
  • Integrals: Parsing of definite and indefinite integrals (\int).
  • Differentials: Parsing of differential expressions.
  • Trigonometric functions: Parsing of all standard and inverse trigonometric functions.
  • Roots: Parsing of square roots and nth roots (\sqrt).
  • Absolute value: Parsing of absolute value expressions.
  • Grouping: Parentheses and LaTeX groupings (\left(...\right)).
  • Indexing: Array and matrix indexing.
  • Lists and sets: Parsing of lists ([1,2,3]) and sets (\{1,2,3\}).
  • Identifiers and constants: Unicode and ASCII identifiers, mathematical constants (e.g., \pi, e, \infty).
  • Numbers: Integer and floating-point literals.
  • Booleans and strings: Parsing of boolean (true, false) and string literals.
  • Matrix environments: Parsing of LaTeX matrix environments (e.g., matrix, pmatrix, etc.).
