• @PanicsAtCaller Public Method WordWrap(width: Int): String method #

  Its lines filled with words up to width columns each, as a terminal shows them, with DisplayWidth and a tab going on to the next multiple of 8 columns: each line breaks before the word that would go past it, at the spaces before that word, which go, while the spaces between words that stay on a line stay as they are. A no-break space, U+00A0, U+2007, or U+202F, is part of its word, not a place to break. A line's leading whitespace starts each line it becomes, and a word wider than the rest of the width is broken between its grapheme clusters. Panics when width is below 1.

  Examples

  Copy

  Expect("the quick brown fox".WordWrap(10) == "the quick\nbrown fox")
  Expect("a\nb".Indent("> ") == "> a\n> b")

• Public Method Dedent(): String method #

  A copy without the leading spaces and tabs that each line that isn't blank starts with, all alike, as when text is written indented in code. A blank line becomes empty.

• Public Method Indent(prefix: String): String method #

  A copy with prefix before each line that isn't blank.
