Syntax Editor Auto‑Completion – Missing Support for User‑Defined Functions

Question

Auto‑Completion Behavior
The SPSS Syntax Editor’s auto‑completion feature lists only built‑in commands and ignores user‑defined functions or macros declared in the current session. After a function is defined, the completion list remains unchanged until the editor is closed and reopened.
Current documentation in the SPSS User Guide’s “Editor and Syntax” section does not mention any mechanism to extend auto‑completion to custom syntax elements. Users report that a manual editor restart is the only way to see newly defined functions appear.
Unresolved Decision
It is unclear whether IBM plans to expose an API or configuration setting that would allow the auto‑completion engine to refresh and incorporate user‑defined functions in future SPSS releases.
Questions

Is there an API or command that can be invoked to refresh the auto‑completion list after defining a new function?
Will forthcoming SPSS versions provide a configuration option to include user‑defined functions in the auto‑completion suggestions?
Is there a documented, non‑restart workaround to trigger a refresh of the auto‑completion list?

Tasadduq Burney · Answer

The SPSS Syntax Editor auto-completion engine does not support user-defined functions (UDFs) or macros defined within the active session. The engine relies on a static index of built-in commands and keywords that is loaded when the editor initializes, rather than dynamically parsing the current session memory.

Current Limitations
There is no API, internal command, or configuration setting to refresh the auto-completion list after a function is defined. The editor's IntelliSense-like functionality is decoupled from the interpreter's symbol table; while the interpreter can execute your custom functions immediately, the UI component does not recognize them as valid tokens for suggestion.

Workaround Steps
Since a manual refresh is unavailable, use the following steps to ensure custom functions appear in suggestions:

Save your current syntax script to a sps file.
  Close the Syntax Editor window completely.
  Reopen the file or restart the SPSS Statistics application.
  Wait for the editor to re-index the file before attempting auto-completion again.

To provide a more specific alternative, are you defining these functions via the DEFINE command or through an external Python/R integration within SPSS?
