Loom

Version: 0.18.0

Loom is a cross-platform Go CLI for UI layout analysis, Pattern catalog validation, transfer planning, and workflow diagnostics.

What Loom does today

• Parse WinUI XAML and normalize it into Loom’s shared layout model (inspect:xaml).
• Render parsed layouts as a compact plaintext ASCII tree (inspect:ascii).
• Validate and lint the Patterns catalog (patterns:validate, patterns:lint).
• Transfer-plan layout compatibility between WinUI and SwiftUI (patterns:transfer).
• Audit accessibility/layout quality for unsupported boundaries, small targets, malformed or redundant structures, and scan-friendly risks (accessibility:audit).
• Run manifest validation (config:validate / config:schema).
• Report errors for Swift-like analysis, XAML parsing, manifests, and patterns (inspect:errors).
• Provide curated cross-platform error guidance and suggested fixes (suggestions:os-errors).
• Provide CLI self-diagnostics and guard reporting (status, verify, checks:command-catalog, guards:summary, self-heal:plan).

The following commands are retained in the catalog for parity but are intentionally not yet implemented in the Go runtime. They return a clear message when invoked:

• inspect:source
• inspect:parity
• graph:components
• generate:xaml
• generate:swiftui
• generate:contracts
• project:build
