* Fix bugs related to named wildcard patterns vs regular wildcard patterns.
* Fix handling of extra nodes during query analysis. Previously, the
expected child_index was updated incorrectly after an extra node,
leading to false "impossible pattern" errors.
* Refine logic for avoiding unnecessary state-splitting due to fallible steps.
Compute *two* different analysis results related to step fallibility:
* `root_pattern_guaranteed` which, like before, summarizes whether the
entire pattern is guaranteed to match once this step is reached.
* `parent_pattern_guaranteed` - which just indicates whether the
immediate parent pattern is guaranteed. This is now used when
deciding whether it's necessary to split a match state.

Tree-sitter CLI
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
nodeon your PATH. - To run and test parsers, you must have a C and C++ compiler on your system.
Commands
-
generate- Thetree-sitter generatecommand will generate a Tree-sitter parser based on the grammar in the current working directory. See the documentation for more information. -
test- Thetree-sitter testcommand will run the unit tests for the Tree-sitter parser in the current working directory. See the documentation for more information. -
parse- Thetree-sitter parsecommand will parse a file (or list of files) using Tree-sitter parsers.
