feat(c430): add Do Not Use Undocumented Functions rule - #28
Merged
Conversation
Reports calls to TI functions that IBM does not document or support (DimensionElementInsertByAlias, LockOn, Hex, ...). Such functions carry no compatibility guarantee and are not covered by support, so production code should stay on the documented API. Matching is AST-based like C510: case-insensitive, found in IF/WHILE conditions and nested arguments, and reported for paren-less no-arg calls (`LockOn;`) while a plain identifier read (`nX = IsNull + 2`) is not. A token fallback recovers findings from statements the parser cannot read. Enabled by default. Intentional use is suppressed inline with `# noqa: C430` or project-wide via the rule's `allowed_functions` setting. Assisted by: Claude Code
