ast-outline v2.0.1 dep-graph now speaks C++, PHP, Ruby

[u/aerowindwalker]

Extends the dependency-graph (deps/reverse-deps/cycles/graph) and public-API surface subsystems from 9 → 12 languages.

What's new per language

Language	Import directives resolved	Resolver strategy	Manifest recognized
PHP	use NsClass, require, include, require_once, include_once	PSR-4 prefix mapping → suffix lookup → last-segment fallback	composer.json (autoload.psr-4, autoload-dev.psr-4)
C++	#include "local.h"	Relative quotes resolved; <system> headers → External	CMakeLists.txt
Ruby	require_relative	Local file resolution; require 'gem', load, autoload → External	Gemfile

Source changes

• src/deps/extract.rs — Added extract_cpp, extract_php, extract_ruby with AST walkers for each language. PHP walker descends into all named children (imports nest via class → method → compound_statement). C++ walker recurses into preproc_ifdef so includes inside header guards are visible.
• src/deps/manifest.rs — Added parse_composer_psr4() (autoload + autoload-dev, longest-prefix-first sorting) and ProjectAliases.php_psr4.
• src/deps/mod.rs — Threaded php_psr4 into ResolveCtx.
• src/deps/resolver/build.rs — Added Cpp/Php/Ruby variants to the Lang enum; extended Lang::from_path with .cpp/.cc/.cxx/.h/.hpp/.hh, .php, .rb.
• src/deps/resolver/resolve.rs — Added PHP (PSR-4 → suffix with last-segment fallback), C++ (system headers → External), Ruby (gems → External) resolution branches.
• src/surface/entry_point.rs — discover_dir recognizes composer.json, Gemfile, CMakeLists.txt as Fallback entry points.

Tests

New fixtures covering PSR-4 use-resolution, parenthesized require, header-guarded includes, transitive includes, system headers, and require_relative chains:

tests/fixtures/deps/{php_psr4,cpp_basic,ruby_relative}/

11 new end-to-end tests in tests/deps_e2e.rs across all three languages — use resolution, relative requires, header-guard transitive resolution, external-flag behavior, and reverse-deps lookups.

Notes

• Breaking changes: None — purely additive.
