Regex Visualizer

Visualize regular expressions as 颜色-coded diagrams with live testing, presets, and detailed explanation

关于 Regex Visualizer

Visualize regular expressions as 颜色-coded diagrams with live testing, presets, and detailed explanation — understand any regex pattern at a glance.

如何使用 Regex Visualizer

  1. 1Type or paste a regular expression in 输入字段.
  2. 2查看color-coded visual diagram: literals, groups, character classes, quantifiers, anchors, and specials。
  3. 3Enter a test string to see matches highlighted in 实时.
  4. 4阅读分解正则表达式各个部分的详细说明。
  5. 5使用cheat sheet icons来quickly insert common patterns (digits, word chars, whitespace, etc.)。

提示

  • 可视化图示让复杂的正则表达式比阅读原始语法更易于调试。
  • Test with edge cases — empty strings, special characters, and long inputs — to 确保 your regex is robust.
  • 当您需要分组但不需要捕获匹配时，请使用非捕获组 (?:...)。
