The expression-language is a lightweight calculation component and parser tool that compiles and evaluates single-line string expressions against runtime variables. It functions as an expression engine that parses logical expressions into executable code or evaluates them directly against provided variables and functions to power dynamic rule evaluation and configuration. The engine features a complete architecture covering lexical tokenisation, intermediate code generation, and execution caching. It parses expression strings into hierarchical abstract syntax trees to enable programmatic insp

Parser is a Ruby source code parser that converts raw source text into structured abstract syntax trees for static analysis and code manipulation. It features dynamic dispatch mechanisms that select specific grammar and tokeniser implementations at runtime, supporting both the executing interpreter version and explicitly targeted language specification versions. The library constructs abstract syntax tree nodes as frozen, immutable objects while tracking exact source file coordinates and character ranges for each node. Developers can supply custom builder objects to control how tree nodes ar
