A Collection of Isabelle Programming Hacks

Isabelle Hacks

This project contains small Isabelle "hacks" that provide additional functionality to Isabelle or showcase specific functionality. The individual hacks usually consist out of a single theory file and all documentation is contained in that theory file. The master branch should work with the latest official release of Isabelle (Isabelle 2022, at time of writing), hacks for older versions might be available on a dedicated branch.

List of Isabelle Hacks

• Assert.thy provides a new top level command assert that provides a simple way for specifying assertions that Isabelle checks while processing a theory.

• Code_Reflection.thy provides a new top-level command for reflecting generated SML code into Isabelle's ML environment.

• Fxp.thy provides Isabelle support for The Functional XML Parser (fxp).

• Hiding_Type_Variables.thy provides print a setup for defining default type variables of type constructors. The default type variables can be hidden in output, e.g., ('a, 'b, 'c) foo is shown as (_) foo. This shorthand notation can also be used in input (using a parse translation), which (sometimes) helps to focus on the important parts of complex type declarations.

• Ml_Yacc_Lib.thy provides Isabelle support for parser generated by ml-yacc (part of sml/NJ).

• Simple_Oracle.thy provides an example on integrating an external tool as simple oracle or counter example generator, similar to the built-in quickcheck.

No Longer Maintained Hacks

• Nano_JSON.thy (support for a JSON-like data exchange for Isabelle/HOL) has been developed into an AFP entry "Nano_JSON", which contains documentation and examples for using JSON encoded data with Isabelle/HOL and Isabelle/ML.
