0.2.0 - 2026-04-20

Fixed

• mix view no longer crashes with ArgumentError: not an atom when analyzing projects that use __MODULE__.Child.func() style qualified calls. The PubSub wrapper collector and flow extractor now treat such references as unresolvable rather than attempting to stringify the AST tuple.

0.1.0 - 2026-04-20

Initial public release.

Added

• mix view Mix task that analyzes an Elixir project and generates a self-contained interactive HTML visualization.
• City view — 3D software city built with Three.js. Modules are buildings (height = lines of code), namespaces are districts, dependencies are arcs between buildings. Isometric camera with pan, zoom, and click-to-focus district detail view.
• ERD view — Entity-Relationship Diagram for Ecto schemas, grouped by Phoenix context. Cross-boundary associations highlighted. Schemas start expanded; click to collapse.
• AST-based analysis — modules and ERD schemas extracted via Code.string_to_quoted/2. No compilation of the target project required; Ecto does not need to be a dependency of ExCodeView.
• Coupling analysis — cross-module dependencies read from the Mix compiler manifest.
• Pluggable views via the ExCodeView.View behaviour. Third-party packages can register views with config :ex_code_view, views: [MyView].
• Pluggable schema extractors via the ExCodeView.SchemaExtractor behaviour (bundled: Ecto).
• Unified shell — single HTML template with tab navigation between views, browser-history-aware back/forward, and persisted per-view settings.
• CLI parameterization — --source-dir, --extensions, --exclude, --output, --output-dir, --output-template, --open, --json, --list, --view.
• Application config under the :ex_code_view key for setting defaults.
• usage_rules integration — ships main rules plus sub-rules (views, schema-extractors, viewer-js) and pre-built skills (add-visualization, configure-ex-code-view) for LLM-assisted use and extension.
• Programmatic API — ExCodeView.analyze/2 returns a %ExCodeView.Schema.Analysis{} struct for custom viewers or tooling.
