run(self, text, pos=0, search=False)

source code

Execute a search.

Overrides: base.BaseEngine.run

__run(self, graph, state, search=False)

source code

Run a sub-search. We support multiple searches (stacks) so that we can invoke the same interpreter for lookaheads etc.

This is a simple trampoline - it stores state on a stack and invokes the visitor interface on each graph node. Visitor methods return either the new node and state, or raise Fail on failure, or Match on success.
