Changelog

[0.11.0]

Compare

Added

  • New ControlSequences8Bit option to treat 8-bit ECMA-48 (C1) escape sequences as zero-width. (#22)

Changed

  • Upgraded uax29 dependency to v2.7.0 for 8-bit escape sequence support in the grapheme iterator.
  • Truncation now validates that preserved trailing escape sequences are zero-width, preventing edge cases where non-zero-width sequences could leak into output.

Note

  • ControlSequences8Bit is deliberately ignored by TruncateString and TruncateBytes, because C1 byte values (0x80–0x9F) overlap with UTF-8 multi-byte encoding.

[0.10.0]

Compare

Added

  • New ControlSequences option to treat ECMA-48/ANSI escape sequences as zero-width. (#20)
  • TruncateString and TruncateBytes now preserve trailing ANSI escape sequences (such as SGR resets) when ControlSequences is true, preventing color bleed in terminal output.

Changed

  • Removed stringish dependency; generic type constraints are now inline ~string | []byte.
  • Upgraded uax29 dependency to v2.6.0 for ANSI escape sequence support in the grapheme iterator.

[0.9.0]

Compare

Changed

  • Unicode 17 support: East Asian Width and emoji data updated to Unicode 17.0.0. (#18)
  • Upgraded uax29 dependency to v2.5.0 (Unicode 17 grapheme segmentation).

[0.8.0]

Compare

Changed

  • Performance: ASCII fast path that applies to any run of printable ASCII. 2x-10x faster for ASCII text vs v0.7.0. (#16)
  • Upgraded uax29 dependency to v2.4.0 for Unicode 16 support. Text that includes Indic_Conjunct_Break may segment differently (and more correctly). (#15)

[0.7.0]

Compare

Added

  • New TruncateString and TruncateBytes methods to truncate strings to a maximum display width, with optional tail (like an ellipsis). (#13)

[0.6.2]

Compare

Changed

  • Internal: reduced property categories for simpler trie.

[0.6.1]

Compare

Changed

  • Perf improvements: replaced the ASCII lookup table with a simple function. A bit more cache-friendly. More inlining.
  • Bug fix: single regional indicators are now treated as width 2, since that is what actual terminals do.

[0.6.0]

Compare

Added

  • New StringGraphemes and BytesGraphemes methods, for iterating over the widths of grapheme clusters.

Changed

  • Fast ASCII lookups

[0.5.0]

Compare

Added

  • Unicode 16 support
  • Improved emoji presentation handling per Unicode TR51

Changed

  • Corrected VS15 (U+FE0E) handling: now preserves base character width (no-op) per Unicode TR51
  • Performance optimizations: reduced property lookups

Fixed

  • VS15 variation selector now correctly preserves base character width instead of forcing width 1

[0.4.1]

Compare

Changed

  • Updated uax29 dependency
  • Improved flag handling

[0.4.0]

Compare

Added

  • Support for variation selectors (VS15, VS16) and regional indicator pairs (flags)

[0.3.1]

Compare

Added

  • Fuzz testing support

Changed

  • Updated stringish dependency

[0.3.0]

Compare

Changed

  • Dropped compatibility with go-runewidth
  • Trie implementation cleanup
