Change Log

0.8.0 - 2021-12-21

• Main idea: Update the Template API in order to match the Pattern API updates
• Update Template API functions
  • Remove validate-statement-vs-template functions
  • Change template->validator to compile-templates->validators
    • Accepts multiple templates; can filter using :selected-templates
  • Change profile->validator to compile-profiles->validators
    • Accepts multiple profiles; can filter using :selected-profiles and :selected-templates
  • Change validate-statement-vs-profile to just validate-statement
    • Add multiple public validation helper functions that validate-statement calls
    • Rename kwargs: :option and :result OCaml-isms to :filter and :errors, respectively
    • Add :all-valid? kwarg to specify that ALL templates have to match for the statement
    • Add :short-circuit? kwarg to specify that only the first validation error should be returned
• Remove automatic JSON string to EDN coercion (note: affects Pattern API also)
• Apply Template ID clash check to compile-patterns->fsms (note: affects Pattern API)
• Update template validation result map
  • :rule can now also be :prop or :sref to distinguish between different types of errors/failures better
  • :vals field in template error map is now always be a vector, even for Statement Ref errors
  • Change:determining-property and :prop-vals to :det-prop and :match-vals, respectively
  • Change :failure to :sref-failure
• Move profile, template, and statement asserts and coercions to util namespaces.
• Move profile->id-template-map and statement-batch->id-statement-map convenience fns to the new template.statement-ref namespace.
• Make ?statement-ref-opts a non-optional (albeit nilable) arg for template/create-template-predicate and template/create-template-validator.
• Spec fixes:
  • FSMs/Patterns:
    • Update fsm-spec/valid-transition-src-states? such that source states only have to be a subset, not equals to, the total states.
    • Add :meta? to spec for fsm/plus-nfa.
    • Correct instrumentation for read-next to work with NFAs as well as DFAs.
    • Fix subregistration specs in utils/statement.
  • Templates:
    • Let statement-ref/get-template-fn and statement-ref/get-statement-fn specs to allow for nil returns and fix arg generation.
    • Add missing :every-val-present? entry to ::template/pred spec.
    • Fix validator-spec, create-template-validator and create-template-predicate template specs.
  • Persephone API
    • Fix typo in ::persephone/validator-fn and ::persephone/predicate-fn spec names.
    • Align specs for validate-statement-errors and validate-statement (for :fn-type :errors).
    • Add missing ::persephone/print? spec for match-statement.
    • Fix bugs relating to the ::persephone/error spec.

0.7.4 - 2021-12-15

• Fix bug where the :selected-profiles kwarg for compile-profiles->fsms did not work.

0.7.3 - 2021-12-15

• Print match failures (if :print? is true) even if it was not the first time that failure was encountered.
• Add :nfa-meta key to the pattern FSMs map (in case meta is lost from :nfa).

0.7.2 - 2021-12-14

• Make FSM compilation thread-safe by removing use of internal atoms.
• Update non-arg s/cat specs to s/tuple specs.

0.7.1 - 2021-12-14

• Expose get-subregistration-id function in utils.statement namespace.

0.7.0 - 2021-12-14

• Main idea: Completely overhaul the Pattern API.
• Remove the following functions:
  • profile->fsms
  • match-statement-vs-pattern
  • match-statement-vs-profile
  • match-statement-batch-vs-pattern
  • match-statement-batch-vs-profile
• Add the following functions (see README and docstrings for details on the new functions):
  • compile-profiles->fsms, which accepts a coll of Profiles and returns a nested map from Profile ID to Pattern ID to FSM map.
  • match-statement, which accepts a compiled Profile coll, a state info map (which has been updated; see README for details), a Statement, and an optional :print? keyword arg.
  • match-statement-batch, which is the same as above except it accepts a Statement coll.
  • Note that the above matching functions now return an {:error ...} map instead of throwing an exception upon error.
• Change the following functions in the pattern namespace:
  • update-children has been made private.
  • pattern->fsm has been made private.
  • pattern-tree->fsm has been renamed to pattern-tree->dfa.
  • pattern-tree->nfa has been added.
  • read-visited-templates has been added.
• Add new util.profile, util.statement, and pattern.errors namespaces.
• Update fsm/read-next to:
  • dispatch on the :type field of the FSM.
  • accept and return a set of maps, instead of a single map.
  • accept an optional start-opts map (currently :record-visit? is the only accepted field).
• NFA construction functions now accept an optional meta? argument; if true, the returned NFAs have a :states map in the metadata.

  • Move fsm and fsm-spec to pattern directory
