writeHints method

void writeHints(
  1. RenderOutput out,
  2. PromptTheme theme, {
  3. int? bulletsPerLine,
})

Writes hints directly to a RenderOutput, handling all hint styles.

If bulletsPerLine is provided and the style is HintStyle.bullets, the hints will be chunked into multiple lines to avoid terminal wrapping issues.

Implementation

void writeHints(RenderOutput out, PromptTheme theme, {int? bulletsPerLine}) {
  switch (theme.features.hintStyle) {
    case HintStyle.bullets:
      final entries = toHintEntries();
      if (bulletsPerLine != null && bulletsPerLine > 0) {
        for (var i = 0; i < entries.length; i += bulletsPerLine) {
          final chunk =
              entries.sublist(i, min(i + bulletsPerLine, entries.length));
          final segments =
              chunk.map((e) => HintFormat.hint(e[0], e[1], theme)).toList();
          out.writeln(HintFormat.bullets(segments, theme));
        }
      } else {
        out.writeln(toHintsBullets(theme));
      }
      break;
    case HintStyle.grid:
      out.writeln(toHintsGrid(theme));
      break;
    case HintStyle.inline:
      final entries = toHintEntries();
      final hints = entries.map((e) => '${e[0]}: ${e[1]}').toList();
      out.writeln(HintFormat.comma(hints, theme));
      break;
    case HintStyle.none:
      break;
  }
