The plugin is still in an experimental state. It is not very user friendly (lack of good error messages) and still contains bugs. But is useable enough to "translate" a large chunck of standard library.
The plugin is believed to work with Coq ≥ 8.7. One way to test the plugin is to follow the following steps:
Retrieve the plugin and compile it:
git clone ... cd paramcoq git checkout master # or v8.x depending on Coq version make make install
To test the plugin:
cd test-suite make ide
It will compile Parametricity.vo which loads the plugin. Then, it launches CoqIDE with some simple examples.
The default arity is 2.
- Parametricity ident as name [arity n].
Declare the translation named name from the translation of the constant or inductive ident.
- Parametricity [Recursive] ident [arity n] [qualified].
The default name for the translation of the constant or inductive ident is automatically generated (from its unqualified name).
You can use the
Recursive option to recursively translate all the constants and inductives which are used by ident.
You can use the
qualified option to use a qualified default name for the translated constants and inductives. The default name then has the form
Module_o_Submodule_o_ident if ident lies in the
- Parametricity Translation term [as name] [arity n].
Define a new constant named name obtained by computing the parametricity translation of term.
- Parametricity Module modulepath.
Recursively translate everything in a module.
- Realizer constant or variable [as name] [arity n] := term.
Declare term to be the translation of a constant. Useful to translate terms containing section variables, or axioms.
Note that both translating a term or module may lead to proof obligations (for some fixpoints and opaque terms if you did not import
- [Global | Local] Parametricity Tactic := t.
Use the tactic t to solve proof obligations generated by the
