"""Classes and functions to register audit checks for various parts of
Spack and run them on-demand.
To register a new class of sanity checks (e.g. sanity checks for
compilers.yaml), the first action required is to create a new AuditClass
object:
.. code-block:: python
audit_cfgcmp = AuditClass(
tag='CFG-COMPILER',
description='Sanity checks on compilers.yaml',
kwargs=()
)
This object is to be used as a decorator to register functions
that will perform each a single check:
.. code-block:: python
@audit_cfgcmp
def _search_duplicate_compilers(error_cls):
pass
These functions need to take as argument the keywords declared when
creating the decorator object plus an ``error_cls`` argument at the
end, acting as a factory to create Error objects. It should return a
(possibly empty) list of errors.
Calls to each of these functions are triggered by the ``run`` method of
the decorator object, that will forward the keyword arguments passed
as input.
