This module contains an algorithm to wordwrap a Unicode string.

Imports

Procs

proc wrapWords(s: string; maxLineWidth = 80; splitLongWords = true; seps: set[char] = Whitespace; newLine = "\n"): string {...}{.noSideEffect, raises: [], tags: [].}

Word wraps s.

Examples:

doAssert "12345678901234567890".wrapWords() == "12345678901234567890"
doAssert "123456789012345678901234567890".wrapWords(20) ==
    "12345678901234567890\n1234567890"
doAssert "Hello Bob. Hello John.".wrapWords(13, false) ==
    "Hello Bob.\nHello John."
doAssert "Hello Bob. Hello John.".wrapWords(13, true, {';'}) ==
    "Hello Bob. He\nllo John."
