Max Brunsfeld 86a891fa63 Fix bugs in parser generation for non-terminal extras 
Previously, we attempted to completely separate the parse states
for item sets with non-terminal extras from the parse states
for other rules. But there was not a complete separation.

It actually isn't necessary to separate the parse states in this way.
The only special behavior for parse states with non-terminal extra rules
is what happens at the *end* of the rule: these parse states need to
perform an unconditional reduction.

Luckily, it's possible to distinguish these *non-terminal extra ending*
states from other states just based on their normal structure, with
no additional state.

Tree-sitter CLI

Build Status Build status Crates.io

The Tree-sitter CLI allows you to develop, test, and use Tree-sitter grammars from the command line. It works on MacOS, Linux, and Windows.

Installation

You can install the tree-sitter-cli with cargo:

cargo install tree-sitter-cli

or with npm:

npm install tree-sitter-cli

You can also download a pre-built binary for your platform from the releases page.

Dependencies

The tree-sitter binary itself has no dependencies, but specific commands have dependencies that must be present at runtime:

  • To generate a parser from a grammar, you must have node on your PATH.
  • To run and test parsers, you must have a C and C++ compiler on your system.

Commands

  • generate - The tree-sitter generate command will generate a Tree-sitter parser based on the grammar in the current working directory. See the documentation for more information.

  • test - The tree-sitter test command will run the unit tests for the Tree-sitter parser in the current working directory. See the documentation for more information.

  • parse - The tree-sitter parse command will parse a file (or list of file) using Tree-sitter parsers.
