# Isabelle Hacks
|
|
|
|
This project contains small Isabelle "hacks" that provide additional
|
|
functionality to [Isabelle](https://isabelle.in.tum.de) 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 2021, at time of writing), hacks for
|
|
older versions might be available on a dedicated branch.
|
|
|
|
## List of Isabelle Hacks
|
|
|
|
* [Assert.thy](Assert.thy) provides a new top level command **assert**
|
|
that provides a simple way for specifying assertions that Isabelle
|
|
checks while processing a theory.
|
|
|
|
* [Hiding_Type_Variables.thy](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.
|
|
|
|
* [Nano_JSON.thy](Nano_JSON.thy) provides support for a JSON-like
|
|
data exchange for Isabelle/HOL.
|
|
|
|
* [Code_Reflection.thy](Code_Reflection.thy) provides a new top-level
|
|
command for reflecting generated SML code into Isabelle's ML
|
|
environment.
