clojure.tools.analyzer.ast.query — buttle 0.1.0

Utilities for querying tools.analyzer ASTs with Datomic

db clj

(db asts)

Given a list of ASTs, returns a representation of those that can be used as a database in a Datomic Datalog query

q clj

(q query asts & inputs)

Execute a Datomic Datalog query against the ASTs. The first input is always assumed to be an AST database, if more are required, it's required to call db on them. unfold-expression-clauses is automatically applied to the query.

query-map clj

(query-map query)

Transoforms a Datomic query from its vector representation to its map one. If the given query is already in its map representation, the original query is returned.

resolve-calls clj

(resolve-calls query)

Automatically replace fn name symbols in expression clauses with their namespace qualified one if the symbol can be resolved in the current namespace.

unfold-expression-clauses clj

(unfold-expression-clauses query)

Given a Datomic query, walk the :where clauses searching for expression clauses with nested calls, unnesting those calls.

E.g {:where [[(inc (dec ?foo)) ?bar] ..] ..} will be transformed in {:where [[(dec ?foo) ?1234] [(inc ?1234) ?bar] ..] ..}
