a948cb3ea0 Allow normal reductions that pop to the initial error state 2016-03-10 11:56:10 -08:00

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.

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.

b733b0cc81 Remove duplicate parse actions
This has only come up for out-of-context states, but it seems possible now that there
could be duplicate actions for any state, because of the possibility of multiple
actions with different precedence or associativity that are otherwise the same

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.
