deps-bundler

Gemfile support for deps-lsp.

This crate is part of the deps-lsp workspace. It provides Bundler-specific functionality including Gemfile DSL parsing, dependency extraction, and rubygems.org registry integration, and implements deps_core::Ecosystem.

Features

• Gemfile parsing — Parse Gemfile with position tracking via a regex-based DSL parser
• Lock file parsing — Extract resolved versions from Gemfile.lock
• rubygems.org registry — HTTP client for version lookups and package search
• Version resolution — Ruby-aware version matching with pessimistic operator (~>)
• Dependency sources — Support for registry, git, path, and github dependencies
• Group handling — Handle :development, :test, :production groups
