IDLdoc support will be added to the IDL Workbench in an update planned for June. This will add some really cool features for those who use IDLdoc and the Workbench:
- enhanced hover help on routines with an IDLdoc header
- content assistant on tag names when writing IDLdoc comments
- menu item and keyboard shortcut to insert an IDLdoc routine or file header (and preferences to define what tags you want inserted)
The Workbench will recognize comments in the rst format.
There will be an IDLdoc 3.1 release any day now to add some features necessary to support this and fix a couple bugs.
