* Requery parse table after breaking down parse stack due to invalid lookahead
* Include Ruby parser in randomized test suite
Ruby and PHP are our only two languages that use non-terminal extras.
Adding Ruby uncovered some bugs.
* Print edited source code when running parse --edit w/ debug flag
* Recompute lookahead when breaking down stack on invalid lookahead
* Fix stack summary leak when there are two discontinuities on a stack version
Courtesy of @Eli-Zaretskii, these fixes should unblock people from
building tree-sitter with MinGW.
I don't think this is an unreasonable maintenance burden, especially
given the Emacs project's interest in using tree-sitter, but
@maxbrunsfeld gets the final call.
When debugging a test with 'script/test -D', the DOT-graph generation
code was sometimes causing reallocations that were not captured by the
allocation tracker, because we explicitly disable allocation-tracking
for that method in order to reduce noise when debugging memory leaks.
By growing the relevant array *prior* to turning off allocation
tracking, we can ensure that it is not reallocated within that function,
avoiding false positive memory leak errors.
Fixes#302
