Isabelle/Eclipse

Eclipse integration for Isabelle proof assistant

Tooltips

Hovering over proof elements opens a tooltip with additional information about the element under the cursor.

Isabelle tooltip

This provides a lot of information about proof elements without cluttering the editor:

  • Types of variables and constants (starting with ::, e.g. :: nat list above)
  • Full names of operators, commands, etc.
  • Some command results and prover messages
  • Term kind of the larger area
  • … and more, depending on the element

This functionality is available both in the Isabelle theory editor and the Prover Output view.

Annotation tooltips

Hovering over annotation icons on the left side of the editor also produces tooltips with annotation information, such as prover messages, error or warning information, etc.
