指令转换器 ​

¥Directives transformer

适用于 @apply、@screen 和 theme() 指令的 UnoCSS 转换器：@unocss/transformer-directives。

¥UnoCSS transformer for @apply, @screen and theme() directives: @unocss/transformer-directives.

安装 ​

¥Installation

bash
pnpm add -D @unocss/transformer-directives
bash
yarn add -D @unocss/transformer-directives
bash
npm install -D @unocss/transformer-directives
ts
// uno.config.ts
import { defineConfig } from 'unocss'
import transformerDirectives from '@unocss/transformer-directives'

export default defineConfig({
  // ...
  transformers: [
    transformerDirectives(),
  ],
})

用法 ​

¥Usage

@apply ​

css
.custom-div {
  @apply text-center my-0 font-medium;
}

将转变为：

¥Will be transformed to:

css
.custom-div {
  margin-top: 0rem;
  margin-bottom: 0rem;
  text-align: center;
  font-weight: 500;
}

--at-apply ​

为了与 vanilla CSS 兼容，你可以使用 CSS 自定义属性来替换 @apply 指令：

¥To be compatible with vanilla CSS, you can use CSS custom properties to replace the @apply directive:

css
.custom-div {
  --at-apply: text-center my-0 font-medium;
}

默认情况下启用此功能并带有一些别名，你可以通过以下方式配置或禁用：

¥This feature is enabled by default with a few aliases, that you can configure or disable via:

js
transformerDirectives({
  // the defaults
  applyVariable: ['--at-apply', '--uno-apply', '--uno'],
  // or disable with:
  // applyVariable: false
})

添加引号 ​

¥Adding quotes

要使用 : 的规则，你必须引用整个值：

¥To use rules with :, you will have to quote the whole value:

css
.custom-div {
  --at-apply: "hover:text-red hover:font-bold";
  /* or */
  @apply 'hover:text-red hover:font-bold';
}

在 @apply 之后使用引号是可选的，以满足某些格式化程序的行为。

¥Using quotes after @apply is optional, to meet the behavior of some formatters.

@screen ​

@screen 指令允许你创建通过名称引用断点的媒体查询，该指令来自 theme.breakpoints。

¥The @screen directive that allows you to create media queries that reference your breakpoints by name comes from theme.breakpoints.

css
.grid {
  --uno: grid grid-cols-2;
}
@screen xs {
  .grid {
    --uno: grid-cols-1;
  }
}
@screen sm {
  .grid {
    --uno: grid-cols-3;
  }
}
/* ... */
...

将转变为：

¥Will be transformed to:

css
.grid {
  display: grid;
  grid-template-columns: repeat(2, minmax(0, 1fr));
}
@media (min-width: 320px) {
  .grid {
    grid-template-columns: repeat(1, minmax(0, 1fr));
  }
}
@media (min-width: 640px) {
  .grid {
    grid-template-columns: repeat(3, minmax(0, 1fr));
  }
}
/* ... */

断点变体支持 ​

¥Breakpoint variant support

@screen 还支持 lt、at 变体：

¥@screen also supports lt、at variants:

@screen lt- ​

css
.grid {
  --uno: grid grid-cols-2;
}
@screen lt-xs {
  .grid {
    --uno: grid-cols-1;
  }
}
@screen lt-sm {
  .grid {
    --uno: grid-cols-3;
  }
}
/* ... */

  }
}
@media (max-width: 639.9px) {

  grid-template-columns: repeat(2, minmax(0, 1fr));
}
@media (min-width: 320px) and (max-width: 639.9px) {
  .grid {
    grid-template-columns: repeat(1, minmax(0, 1fr));
  }
}
@media (min-width: 1280px) and (max-width: 1535.9px) {
  .grid {
    grid-template-columns: repeat(3, minmax(0, 1fr));
  }
}
@media (min-width: 1536px) {
  .grid {
    grid-template-columns: repeat(4, minmax(0, 1fr));
  }
}
/* ... */

theme() ​

使用 theme() 函数通过点表示法访问主题配置值。

¥Use the theme() function to access your theme config values using dot notation.

css
.btn-blue {
  background-color: theme('colors.blue.500');
}

将被编译为：

¥Will be compiled to:

css
.btn-blue {
  background-color: #3b82f6;
}
