  "readme": "# postcss-calc [![Build Status](https://travis-ci.org/postcss/postcss-calc.png)](https://travis-ci.org/postcss/postcss-calc)\n\n> [PostCSS](https://github.com/postcss/postcss) plugin to reduce `calc()`.\n\nThis plugin reduce `calc()` references whenever it's possible.\nThis can be particularly useful with the [postcss-custom-properties](https://github.com/postcss/postcss-custom-properties) plugin.\n\n**Note:** When multiple units are mixed together in the same expression, the `calc()` statement is left as is, to fallback to the [w3c calc() feature](http://www.w3.org/TR/css3-values/#calc).\n\n## Installation\n\n```console\n$ npm install postcss-calc\n```\n\n## Usage\n\n```js\n// dependencies\nvar fs = require(\"fs\")\nvar postcss = require(\"postcss\")\nvar calc = require(\"postcss-calc\")\n\n// css to be processed\nvar css = fs.readFileSync(\"input.css\", \"utf8\")\n\n// process css\nvar output = postcss()\n  .use(calc())\n  .process(css)\n  .css\n```\n\n**Example** (with [postcss-custom-properties](https://github.com/postcss/postcss-custom-properties) enabled as well):\n\n```js\n// dependencies\nvar fs = require(\"fs\")\nvar postcss = require(\"postcss\")\nvar customProperties = require(\"postcss-custom-properties\")\nvar calc = require(\"postcss-calc\")\n\n// css to be processed\nvar css = fs.readFileSync(\"input.css\", \"utf8\")\n\n// process css\nvar output = postcss()\n  .use(customProperties())\n  .use(calc())\n  .process(css)\n  .css\n```\n\nUsing this `input.css`:\n\n```css\n:root {\n  --main-font-size: 16px;\n}\n\nbody {\n  font-size: var(--main-font-size);\n}\n\nh1 {\n  font-size: calc(var(--main-font-size) * 2);\n  height: calc(100px - 2em);\n}\n```\n\nyou will get:\n\n```css\nbody {\n  font-size: 16px\n}\n\nh1 {\n  font-size: 32px;\n  height: calc(100px - 2em)\n}\n```\n\nCheckout [tests](test) for more examples.\n\n### Options\n\n#### `precision` (default: `5`)\n\nAllow you to definine the precision for decimal numbers.\n\n```js\nvar out = postcss()\n  .use(calc({precision: 10}))\n  .process(css)\n  .css\n```\n\n#### `preserve` (default: `false`)\n\nAllow you to preserve calc() usage in output so browsers will handle decimal precision themselves.\n\n```js\nvar out = postcss()\n  .use(calc({preserve: true}))\n  .process(css)\n  .css\n```\n\n#### `warnWhenCannotResolve` (default: `false`)\n\nAdds warnings when calc() are not reduced to a single value.\n\n```js\nvar out = postcss()\n  .use(calc({warnWhenCannotResolve: true}))\n  .process(css)\n  .css\n```\n\n#### `mediaQueries` (default: `false`)\n\nAllows calc() usage as part of media query declarations.\n\n```js\nvar out = postcss()\n  .use(calc({mediaQueries: true}))\n  .process(css)\n  .css\n```\n\n---\n\n## Contributing\n\nWork on a branch, install dev-dependencies, respect coding style & run tests before submitting a bug fix or a feature.\n\n```console\n$ git clone https://github.com/postcss/postcss-calc.git\n$ git checkout -b patch-1\n$ npm install\n$ npm test\n```\n\n## [Changelog](CHANGELOG.md)\n\n## [License](LICENSE)\n",
