よくある思い込み

Setting chalk.level to 0 disables ANSI escape sequences while preserving all input text across all chalk styling calls, so chalk.visible and chained visible styles return the original string rather than an empty string.

このサンプルの作者が、ここで開発者やモデルが期待するであろうこととして記録したもの。下の契約が実際に実行されたものだ。

コントラクト

• chalk.visible and chained modifiers return an empty string when level is 0 rather than passing through unstyled text
• chalk.red and other standard styles return the original unstyled text when level is 0
• chalk.visible passes through unstyled text when level is 1 or higher
• chained styles like chalk.red.visible and chalk.visible.red apply full ANSI styling when level is 1 or higher regardless of chain order
• chalk.visible with multiple arguments joins them with spaces when level is 1 or higher and returns an empty string when level is 0
• nested chalk.visible calls inside outer styles omit the nested content at level 0 and style the entire composite string at level 1
• dynamically mutating level on a Chalk instance from 1 to 0 immediately switches chalk.visible from passthrough to empty string suppression
