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

pnpm

pnpm add -D @unocss/transformer-directives

yarn

yarn add -D @unocss/transformer-directives

npm

npm install -D @unocss/transformer-directives

bun

bun add -D @unocss/transformer-directives

uno.config.ts

import transformerDirectives from '@unocss/transformer-directives'
import { defineConfig } from 'unocss'

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

提示

该预设包含在 unocss 包中，你也可以从那里导入它：

¥This preset is included in the unocss package, you can also import it from there:

import { transformerDirectives } from 'unocss'

用法

¥Usage

@apply

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

将转变为：

¥Will be transformed to:

.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:

.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:

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:

.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.

.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:

.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-

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

将转变为：

¥Will be transformed to:

.grid {
  display: grid;
  grid-template-columns: repeat(2, minmax(0, 1fr));
}
@media (max-width: 319.9px) {
  .grid {
    grid-template-columns: repeat(1, minmax(0, 1fr));
  }
}
@media (max-width: 639.9px) {
  .grid {
    grid-template-columns: repeat(3, minmax(0, 1fr));
  }
}
/* ... */

@screen at-

.grid {
  --uno: grid grid-cols-2;
}
@screen at-xs {
  .grid {
    --uno: grid-cols-1;
  }
}
@screen at-xl {
  .grid {
    --uno: grid-cols-3;
  }
}
@screen at-xxl {
  .grid {
    --uno: grid-cols-4;
  }
}
/* ... */

将转变为：

¥Will be transformed to:

.grid {
  display: grid;
  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.

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

将被编译为：

¥Will be compiled to:

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

icon()

使用 icon() 函数将图标工具转换为特定的 svg 图标。

¥Use the icon() function to convert the icon utility to a specific svg icon.

警告

icon() 依赖于 @unocss/preset-icons 并将使用配置，请确保你已添加此预设。

¥icon() depends on @unocss/preset-icons and will use the configuration, make sure you have added this preset.

.icon {
  background-image: icon('i-carbon-sun');
}

将被编译为：

¥Will be compiled to:

.icon {
  background-image: url("data:image/svg+xml;utf8,%3Csvg viewBox='0 0 32 32' width='1em' height='1em' xmlns='http://www.w3.org/2000/svg' %3E%3Cpath fill='currentColor' d='M16 12.005a4 4 0 1 1-4 4a4.005 4.005 0 0 1 4-4m0-2a6 6 0 1 0 6 6a6 6 0 0 0-6-6M5.394 6.813L6.81 5.399l3.505 3.506L8.9 10.319zM2 15.005h5v2H2zm3.394 10.193L8.9 21.692l1.414 1.414l-3.505 3.506zM15 25.005h2v5h-2zm6.687-1.9l1.414-1.414l3.506 3.506l-1.414 1.414zm3.313-8.1h5v2h-5zm-3.313-6.101l3.506-3.506l1.414 1.414l-3.506 3.506zM15 2.005h2v5h-2z'/%3E%3C/svg%3E");
}

因为图标默认使用 currentColor 作为填充颜色，如果你想自定义图标的颜色，可以使用 icon('icon name', 'custom color')。

¥Cause the icon uses currentColor as the fill color by default, if you want to customize the color of the icon, you can use icon('icon name', 'custom color').

.icon {
  background-image: icon('i-carbon-moon', '#fff');
  background-image: icon('i-carbon-moon', 'theme("colors.red.500")'); /* use theme color */
}

将被编译为：

¥Will be compiled to:

.icon {
  background-image: url("data:image/svg+xml;utf8,%3Csvg viewBox='0 0 32 32' width='1em' height='1em' xmlns='http://www.w3.org/2000/svg' %3E%3Cpath fill='%23fff' d='M13.503 5.414a15.076 15.076 0 0 0 11.593 18.194a11.1 11.1 0 0 1-7.975 3.39c-.138 0-.278.005-.418 0a11.094 11.094 0 0 1-3.2-21.584M14.98 3a1 1 0 0 0-.175.016a13.096 13.096 0 0 0 1.825 25.981c.164.006.328 0 .49 0a13.07 13.07 0 0 0 10.703-5.555a1.01 1.01 0 0 0-.783-1.565A13.08 13.08 0 0 1 15.89 4.38A1.015 1.015 0 0 0 14.98 3'/%3E%3C/svg%3E");
