* 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
This allows you to assert about fields in tests. But if your test
s-expression does *not* include fields, the fields will be stripped from
the regexp before comparison.
* Rename parse_str to parse and make it polymorphic.
* Rename parse_utf8 to parse_with, since it is now the callback-based
version of parse
* Add a parse_utf16 method analogous to parse
* Rename existing parse_utf16 method to parse_utf16_with
This brings in the changes from tree-sitter/rust-tree-sitter#5
* Structure `cli` crate as both a library and an executable, so that
benchmarks can import code from the crate.
* Import macros in the Rust 2018 style.
