name: add-wp-function description: Add new WordPress function mappings to the wpts transpiler. Use when adding WordPress API functions like post management, taxonomy, user, media, or other WP functions. argument-hint: [function-category]

Add WordPress function mappings for $ARGUMENTS to the wpts transpiler.

Workflow

For each function:

1. Map the function in packages/wpts/src/transpiler/wp-function-map.ts

   • Add camelCase → snake_case entry in the appropriate section
   • Group related functions together with a comment header

2. Add type declaration in packages/wpts/src/runtime/wp-types.ts

   • Add declare function with correct parameter types and return type
   • Verify signatures against https://developer.wordpress.org before adding

3. Add tests in packages/wpts/tests/unit/transpiler/expression-transpiler.test.ts

   • Add test cases verifying camelCase TS transpiles to snake_case PHP
   • Cover representative functions from the category

4. Update README in packages/wpts/README.md

   • Add row to the WordPress Functions table

Verification

After all functions are added, run all three checks:

• npx tsc --noEmit (type checking)
• pnpm test (unit + integration tests)
• pnpm build (compile + template copy)

All three must pass before the task is complete.
