Overview

ucode block-feed — emit a compact per-block Unicode data feed from ucode's canonical output tree.

Reads ucode's output/ and produces three artifacts at the target directory:

<target>/unicode-blocks.json
<target>/unicode-version.json
<target>/unicode/blocks/<slug>.json

Each per-block file contains the codepoints in that block with their compact Unicode metadata (name, general category, script, combining class, bidi class, mirrored flag). Block slugs are derived from the block name via the standard slug algorithm.

  • block_feed_output_root (String, Pathname) —

    target directory.

  • unicode_version (String, nil) (defaults to: nil) —

    UCD version to stamp on unicode-version.json. Defaults to the version recorded in ucode's manifest.json.

Returns:
