unicode-segmenter@0.18.0

Minor Changes

• a6b246a: Add unicode-segmenter/grapheme-counter, a standalone fast counter for extended grapheme clusters.

  countGraphemes() from the new entry returns exactly the same result as the one in unicode-segmenter/grapheme, but runs the boundary rules directly without allocating segment objects or slicing strings:

  • 4~7x faster counting on V8, ~4x on Hermes, with zero allocation
  • Standalone entry (4,852 bytes minified, 2,353 bytes gzipped); doesn't carry the segmenter code, and the segmenter entry doesn't carry the counter - even without tree-shaking
  • The countGraphemes() wrapper in unicode-segmenter/grapheme is unchanged and stays as the convenience API

_{Comparing changeset-release/main (e0217a4) with main (a6b246a)}

I'm debating whether or not to release this.

The fast alternative to the countGraphemes API in unicode-segmenter.

It avoids the iterator protocol overhead of count-only paths, uses no heap, and is at least 4 times faster per segment.

However, most of the code overlaps with the full segmenter. I could either completely replace the existing API with this or provide a separate "lite entry" with the same API.

While it is a good alternative in most cases where only counting is needed, I am concerned that splitting API entries for a snippet that is only 100-200 bytes after compression seems overdesigned.
