tutorial for building a query parser using Ruby, Parslet, and Elasticsearch

A testing framework for Parslet grammars

☯️ A TreeHaver-based merge/templating tool, Ast::Merge provides base classes, modules, and RSpec shared examples for building intelligent file mergers using AST analysis. Works with all Ruby platforms, and all language grammars, yes, including those.

☯️ Intelligently merges TOML files by analyzing their AST structure with tree-sitter, preserving key organization and resolving conflicts based on structural similarity.

☯️ Intelligently merge RBS type signature files by parsing and comparing AST structures. Supports freeze blocks to protect customizations, signature-based matching, and configurable merge strategies.

Exploring how to parse significant indentation with Parslet

🌴 TreeHaver is a cross-Ruby adapter for many AST parsing libraries; supporting MRI Ruby, JRuby, & TruffleRuby. Provides unified parsing API & AST when using ruby_tree_sitter, parslet, citrus, ffi, tree_stump (Rust), JRuby JARs, etc. As Faraday is to HTTP clients, this is for ASTs: "Learn once & write once & run anywhere"
