Erlang ↔ Roc Conversion

Bidirectional conversion between Erlang and Roc. This skill extends meta-convert-dev with Erlang↔Roc specific type mappings, idiom translations, and architectural patterns for moving from process-based concurrency to pure functional programming.

This Skill Extends

• meta-convert-dev - Foundational conversion patterns (APTV workflow, testing strategies)

For general concepts like the Analyze → Plan → Transform → Validate workflow, testing strategies, and common pitfalls, see the meta-skill first.

This Skill Adds

• Type mappings: Erlang dynamic types → Roc static types
• Paradigm translation: Process-based concurrency → Pure functional with Tasks
• Idiom translations: OTP patterns → Roc functional patterns
• Error handling: Let-it-crash + supervisors → Result types
• Concurrency: Erlang processes → Roc platform Tasks
• Module system: Erlang modules → Roc platform/application architecture
