ScriptSpan#

class scikitplot.corpus.ScriptSpan(text, script, direction, start, end)[source]#

A contiguous span of text in a single Unicode script.

Produced by ScriptSegmenter from NFC-normalised text. All index fields refer to grapheme cluster indices (as produced by regex.findall(r'\X', nfc_text)), not raw codepoint offsets.

Parameters:

textstr

The span text (NFC normalised).

scriptScriptType

Detected script for this span.

directionstr

Writing direction: "ltr" | "rtl" | "ttb".

startint

Grapheme cluster index in the parent document (inclusive).

endint

Grapheme cluster index in the parent document (exclusive).

Parameters:

• text (str)

• script (ScriptType)

• direction (str)

• start (int)

• end (int)

Notes

Developer note: Grapheme cluster indices (start, end) refer to the regex.findall(r'\\X', nfc_text) list produced by GraphemeClusterNormalizer, not codepoint offsets. A single emoji with ZWJ may span 3+ codepoints but occupies exactly 1 grapheme cluster index slot.
