| name | advpl-to-tlpp-migration |
| description | Use when the user asks to migrate, convert, compatibilize, or modernize legacy ADVPL procedural code to TLPP object-oriented classes on TOTVS Protheus -- turning User Functions/Static Functions into namespaced classes with methods and data properties, replacing Private/Public scoping, and preserving backward-compatible wrappers for existing callers. Also triggers on Portuguese phrasing like "migrar para tlpp", "compatibilizar fonte", "converter prw para tlpp", "transformar em classe", "modernizar rotina", or requests naming a `custom.<agrupador>.<servico>` / `totvs.protheus.<segmento>.<agrupador>` namespace. |
ADVPL to TLPP Migration
This skill guides the conversion of legacy .prw procedural code (User Functions, Static Functions, Private/Public variables) into modern .tlpp classes with namespace declarations, data properties, and public/private methods -- following the official TOTVS naming conventions (lowercase dot-separated namespaces, PascalCase classes, camelCase methods, no underscores). It defines the migration workflow (analyze -> identify -> map to class design -> user approval -> generate -> checklist -> validate) and mandates keeping the original .prw User Function as a thin backward-compatible wrapper delegating to the new class.
Activate this skill when the user wants an existing procedural routine converted to TLPP, needs help deciding a namespace, or is modernizing multiple #Include directives to .th includes. It does not cover generating brand-new TLPP code that has no ADVPL predecessor (see advpl-code-generation), behavior-preserving cleanup of code that stays in ADVPL (see advpl-refactoring), auditing code quality before migration (see advpl-code-review), or fixing errors encountered during or after migration (see advpl-debugging).
