e7d3d40a59 Explicitly inform stack pop callback when the stack is exhausted
Also, pass non-extra tree count as a single value, rather than keeping
track of the extra count and the total separately.

2e35587161 Use new stack_pop_until function for repairing errors 2016-03-07 20:06:46 -08:00
Max Brunsfeld
4348eb89d4 Expose lower stack nodes via pop_until() function
This callback-based API allows the parser to easily visit each interior node
of the stack when searching for an error repair. It also is a better abstraction
over the stack's DAG implementation than having the public functions for
accessing entries and their successor entries.

b113dc8b0f Return a TreeArray from ts_stack_pop
Since the capacity is now included in the return value, the buffer
can be reused in the ts_parser__accept function. Also, it's just
cleaner to use Array consistently, rather than a separate buffer
and size.
