tegere.query
Functionality for querying a :tegere.parser/features collection, including
preparing said collection for querying by 'projecting' tags from features and
example tables to the scenarios that are the ultimate targets of queries.
Functionality for querying a ``:tegere.parser/features`` collection, including preparing said collection for querying by 'projecting' tags from features and example tables to the scenarios that are the ultimate targets of queries.
filter-featuresclj
(filter-features features indices)Return a substructure of features that matches the sequence of
[feature-idx scenario-idx] in indices. The input and output features
collection conforms to :tegere.parser/features.
Return a substructure of ``features`` that matches the sequence of [feature-idx scenario-idx] in ``indices``. The input and output features collection conforms to ``:tegere.parser/features``.
filter-scenariosclj
(filter-scenarios scenarios indices)Return the sub-collection of scenarios whose positional indices match any
of the indices in indices.
Return the sub-collection of ``scenarios`` whose positional indices match any of the indices in ``indices``.
get-all-scenario-tagsclj
(get-all-scenario-tags features)Given a :tegere.parser/features vector, return a map from scenario paths
within that vector (2-ary vecs of int) to sets of tags belonging to the
scenario at the path. E.g.,
{[0 0] #{manner_of_looking=quizzically chimpanzees fruit-reactions} ...}.
Given a ``:tegere.parser/features`` vector, return a map from scenario paths
within that vector (2-ary vecs of int) to sets of tags belonging to the
scenario at the path. E.g.,
{[0 0] #{manner_of_looking=quizzically chimpanzees fruit-reactions} ...}.queryclj
(query features where)Query the features data structure (conformant to :tegere.parser/features)
using where clause where and returning a substructure of features that
contains only the features and scenarios that match the where clause. The
where clause must be a list-based tree structure that conforms to
::query-tree, i.e., its non-terminal nodes are the symbols 'and 'or or 'not
and its terminal nodes are strings that should match Gherkin tags in the
features. Example usage::
(query features '(and (or chimpanzees orangutan) (not fruit-reactions)))
Query the features data structure (conformant to ``:tegere.parser/features``)
using where clause ``where`` and returning a substructure of ``features`` that
contains only the features and scenarios that match the where clause. The
``where`` clause must be a list-based tree structure that conforms to
``::query-tree``, i.e., its non-terminal nodes are the symbols 'and 'or or 'not
and its terminal nodes are strings that should match Gherkin tags in the
features. Example usage::
(query features '(and (or chimpanzees orangutan) (not fruit-reactions)))set-all-scenario-tagsclj
(set-all-scenario-tags features)Return a modified copy of the :tegere.parser/features vector features
such that each feature's :tegere.parser/scenario contains a ::tags set
containing all of the tags that pertain to that scenario.
Return a modified copy of the ``:tegere.parser/features`` vector ``features`` such that each feature's ``:tegere.parser/scenario`` contains a ``::tags`` set containing *all* of the tags that pertain to that scenario.
user-query->datalog-queryclj
(user-query->datalog-query user-query)Given a user query conformant to ::query-tree (e.g.,
'(and chimpanzees bonobos)), return a datalog query that can be passed to
datascript.core/q. The return value of executing this query will be a set
of 2-ary vectors containing a feature index and a scenario index.
Given a user query conformant to ``::query-tree`` (e.g., '(and chimpanzees bonobos)), return a datalog query that can be passed to ``datascript.core/q``. The return value of executing this query will be a set of 2-ary vectors containing a feature index and a scenario index.
user-query->where-clausesclj
(user-query->where-clauses user-query)Given ::query-tree user-query, return a sequence of datalog 'where'
clauses. Remove all top-level 'and' lists of all clauses.
Given ``::query-tree`` ``user-query``, return a sequence of datalog 'where' clauses. Remove all top-level 'and' lists of all clauses.
