🌰 Demo

CSS 颜色自动抽离变量

我们要重构 \_fixtures 文件夹下 less 样式文件:

  1. 分析文件
lemonj analysis _fixtures

输出代码坏味道:

Code Smell:  {
  colors: 24,
  importants: 4,
  issues: 8,
  mediaQueries: 1,
  absolute: 0,
  oddWidth: 1
}
  1. 每种颜色都重构为一个变量在 mappings.less 中,你可以修改对应的颜色:
// _fixtures/less/color/border.less
@color1: #ddd;
// _fixtures/less/color/border.less
@color2: green;
// _fixtures/less/color/rgba.less
@color3: rgba(255, 0, 0, 0.3);
// _fixtures/less/color/sample.less
@color4: #ff7f50;
// _fixtures/less/color/sample.less
// _fixtures/less/color/sample2.less
@color5: #800080;
// _fixtures/less/color/sample.less
@color6: red;
// _fixtures/less/color/sample.less
// _fixtures/less/color/sample.less
@color7: #428bca;
// _fixtures/less/color/sample.less
@color8: #fff;
// _fixtures/less/color/sample2.less
@color9: #000000;
  1. 运行重构命令:
lemonj refactor _fixtures

此时每个写死的颜色,都抽离到变量中。
