By default invariants checking generates warnings.
If invariants_strict_checking theory option is enabled,
the checking generates errors.
- Update 2018-cicm-isabelle_dof-applications/IsaDofApplications.thy
and 2020-iFM-CSP/paper.thy to pass the checking of
the low level invariant checking function "check"
in scholarly_paper.thy,
which checks that the instances in a sequence of the same class
have a growing level.
For a sequence:
section*[intro::introduction]‹ Introduction ›
text*[introtext::introduction, level = "Some 1"]‹...›
introtext must have a level >= than intro.
- Bypass the checking of high-level invariants
when the class default_cid = "text",
the top (default) document class.
We want the class default_cid to stay abstract
and not have the capability to be defined with attribute,
invariants, etc.
Hence this bypass handles docitem without a class associated,
for example when you just want a document element to be referenceable
without using the burden of ontology classes.
ex: text*[sdf]\<open> Lorem ipsum @{thm refl}\<close>
The functions get_doc_class_global and get_doc_class_local trigger
an error when the class is "text" (default_cid),
then the functions like check_invariants which use it will fail
if the checking is enabled by default for all the theories.

- Make doc_class type and constant used by regular expression
in monitors ground
- Make class tag attribute ground (with serial())
- The previous items make possible
the evaluation of the trace attribute
and the definition of the trace-attribute term annotation
- Warning: the current implementation does yet not support
some use-cases, like invariant on monitors,
or the initialization of docitem without a class associated.
- Add first draft of the checking of invariants.
For now, it is disabled by default because some cases
are not yet supported, like the initialization of docitem
without a class associated.
ex: text*[sdf]‹ Lorem ipsum @{thm refl}›
- To enable the checking, one can use the theory attribute
"invariants_checking" by declaring it in a theory like this:
declare [[invariants_strict_checking = true]]
- A checking using basic tactics (unfolding and auto) can be enable
with the "invariants_checking_with_tactics" theory attribute
for specific use-cases
- The specification of invariants is now automatically abstracted,
so one must define an invariant like this now:
doc_class W =
w::"int"
invariant w :: "w σ ≥ 3"
The old form:
doc_class W =
w::"int"
invariant w :: "λσ. w σ ≥ 3"
is now deprecated.
The specification of the invariant still uses the σ-notation
and is defined globally by the name component "invariantN"
- Update the invariants definition in the theories to match
the new implementation
- Update the manual to explain this new feature
- Add small examples in src/tests/High_Level_Syntax_Invariants.thy
and src/tests/Ontology_Matching_Example.thy
- Fix the generation of the record associated with
a class and used for the logic.
The old implementation generated a new attribute
for each attribute defined by a subclass,
even the ones that were overriding ones of the superclass.
The new implementation generates the attributes of the subclass
which are not overriding ones.
Warning:
It implies that overridden attributes in a subclass are not
new attributes added to the theory context.
So the base name of an attribute will refer to the attribute
of the last declared class where it is defined.
If ones wants to refer to atttributes, one should use
long names, even in the invariants of a subclass definition
which overrides the attribute used in the invariant.
For example,
in ~~/src/ontologies/scholarly_paper/scholarly_paper.thy:
doc_class technical = text_section +
definition_list :: "string list" <= "[]"
status :: status <= "description"
formal_results :: "thm list"
invariant L1 :: "λσ::technical. the (level σ) > 0"
type_synonym tc = technical (* technical content *)
doc_class example = text_section +
referentiable :: bool <= True
status :: status <= "description"
short_name :: string <= "''''"
doc_class math_content = tc +
referentiable :: bool <= True
short_name :: string <= "''''"
status :: status <= "semiformal"
mcc :: "math_content_class" <= "thm"
invariant s1 :: "λ σ::math_content. ¬referentiable σ ⟶ short_name σ = ''''"
invariant s2 :: "λ σ::math_content. technical.status σ = semiformal"
The class math_content overrride the attribute status
of the class technical, by using the type synonym tc,
but the base name of this attribute refers
to the attribute of the class example where it is last defined
and not just overridden.
So in the invariant s2 of the class math_content,
we must use the long name of the attribute,
i.e. the base name "status" with its qualifier which refers
to the superclass where it is defined, the class technical.
Type synonyms as qualifiers are not yet supported.
- Qualify classes that only override attributes of their superclass
as vitual classes by adding a virtual attribute.
This attribute is used to discriminate virtual classes and generate
an adequate make function to initialize their associated record.
The implementation uses an hidden attribute (the tag_attribute)
to force the virtual class to be concrete or the logic
by having a full new record definition associated with it.
For example:
doc_class W =
a::"int" <= "1"
doc_class X = W +
a::"int" <= "2"
The class X is tagged as a virtual class and
the record make functions of the classes W and X are:
W.make W_tag_attribute W_a
X.make X_tag_attribute X_a X_tag_attribute
So a record definition is added to the theory context for each class,
even though a virtual class only overrides
attributes of its superclass.
This behavior allows us to support definitions of new default values
for attributes in the subclass, as shown in the example.
- Factorize make name components
- Use Record name components instead of strings to refer to Record
components
- Fix typos
