0.18.0

• Added APIs to traverse the syntax tree: tsc-traverse-do, tsc-traverse-mapc, tsc-traverse-iter. The traversal is depth-first pre-order.
• Improved syntax tree rendering's performance in tree-sitter-debug.
• Added optional params props and output to tsc-current-node, which allows retrieving node properties, instead of the node object itself. This enables performance optimizations in uses cases that deal with a large number of nodes.

0.17.0

• Added customization option tsc-dyn-get-from, which is a list of sources to get the dynamic module tsc-dyn from. Its default value is (:github :compilation).
• Made tree-sitter-hl's region-fontification function fall back to the underlying non-tree-sitter function when called outside of tree-sitter-hl-mode. This fixes an issue where jupyter-repl-mode's input cells are not highlighted.
• Updated tsc-dyn-get to download platform-specific binaries (mainly for Apple Silicon).

0.16.1

• Modified CI pipelines to publish additional pre-built dynamic modules. Their filenames include the platform they are built for. The files without platform in name will eventually be deprecated.
  • tsc-dyn.x86_64-apple-darwin.dylib (same as tsc-dyn.dylib)
  • tsc-dyn.x86_64-unknown-linux-gnu.so (same as tsc-dyn.so)
  • tsc-dyn.x86_64-pc-windows-msvc.dll (same as tsc-dyn.dll)
  • tsc-dyn.aarch64-apple-darwin.dylib (new, for Apple Silicon)

0.16.0

• Upgraded tree-sitter crate to 0.20.0, which:
  • Changed the semantics of range-restricted query to report matches that intersect the range, instead of only fully-contained matches. See tree-sitter#1130.
  • Fixed an issue where multiple patterns with the same capture names can result in the first capture being omitted.
• Improved performance:
  • Disabled query-region extension. Added a flag to turn it back on: tree-sitter-hl-enable-query-region-extension.
  • Increased default chunk size for parsing from 1024 to 4096.

0.15.2

• Reduced GC pressure by not making the text property face a list if there is only one face.
• Recast tree-sitter-node-at-point as more general tree-sitter-node-at-pos, taking optional POS argument.
• Made tree-sitter-node-at-pos accept special node-type arguments :named and :anonymous.

0.15.1

• Fixed some invalid query patterns causing SIGABRT, by upgrading tree-sitter crate.
• Used keywords to represent auxiliary (invisible) node types. For example: :end, :_expression.

0.15.0

• Upgraded tree-sitter crate to 0.19.3, which:
  • Added negated-field query patterns.
  • Fixed some bugs, mostly query-related.
  • Is required to support newer versions of the language grammars.
  • Raised the minimum and maximum supported language ABI versions to 13. Older versions of the language bundle tree-sitter-langs (before 0.10.0) will not be loaded.

0.14.0

• Added ABI compatibility checks when loading a language object from a dynamic library.
• Made tsc-make-query signal concrete error symbols, instead of rust-panic.

0.13.1

• Used static linking for C runtime on Windows, to avoid having to install VC++ redistributable package.

0.13.0

• Upgraded emacs crate to 0.15.0 to improve performance on Emacs 27+.
• Fixed the highlighting error when exporting org as html, by removing the hack that allows tree-sitter-hl to work without (a major mode) setting up font-lock-defaults.
