A tool to support the description and development of state-and-transition models using the Cypher graph query language.

cymod's Issues

CypherQueryProcessor class

Initialise with a list of CypherFile objects

Provide methods to return a sorted list of cypher queries.

get_sorted_queries(first_query_is_last_element=True, hoist_constraints=True)
By default, the queries are sorted so that the last element in the returned array is a string representing the first cypher query which should be executed. Also by default, any constraints are positioned so they are executed last. This is to avoid an issue with py2neo whereby transactions in which a non-constraint following a constraint is not allowed.

It would be useful if it was possible to trace problematic cypher queries back to its originating file. This will probably involve an...

InvalidCypherError
Print offending cypher
Print file name
Print trace back
End program

This may end up requiring a more elaborate data structure than a sorted list of queries.

Make compatible with Python 2.7

Important to make the module importable in Jython
