Completion and type inference

The language server provides VBA keywords, built-in VBA/Excel/Office/MSForms metadata, project symbols, UserForm controls, and ProgID completion inside CreateObject/GetObject strings. Late-bound variables can acquire a curated type from known ProgIDs, enabling member completion and hover.

For example, type CreateObject("Scripting.Dictionary") and assign it to a variable. xlflow can recognize that well-known ProgID and suggest dictionary members even though VBA would otherwise treat the variable as late-bound. Suggestions are guidance, not a guarantee that a specific Office installation exposes every member; still run the macro to verify behavior.

When completion is missing, confirm the file is a supported source type, the workspace has xlflow.toml, and the language server is running. xlflow type db status reports generated TypeLib data; restart the server after refreshing type data. See VS Code troubleshooting for the exact checks.
