|
||||
|
||||

||||
|
||||
- Added: Support for working in browsers without transpiling ([#36](https://github.com/MoOx/reduce-css-calc/pull/36) - @Semigradsky)
|
||||
- Fixed: `calc(100vw - (100vw - 100%))` does not evaluate to `100%` ([#35](https://github.com/MoOx/reduce-css-calc/pull/35) - @Semigradsky)
|
||||
|
||||
## 2.0.5 - 2017-05-12

|
||||
|
||||
## 2.0.4 - 2017-05-09
|
||||
|
||||
- Fixed: CSS variable regex was overly greedy and caused a crash in some
|
||||
cases. ([#27](https://github.com/MoOx/reduce-css-calc/pull/27) - @andyjansson)
|
||||
|
||||
## 2.0.3 - 2017-05-09
|
||||
|
||||
- Fixed: Regression in handling decimals without having any numbers after
|
||||
the decimal place (e.g. `10.px`).
|
||||
|
||||
## 2.0.2 - 2017-05-08
|
||||
|
||||
- Fixed: Regression in consecutive subtraction handling
|
||||
([#25](https://github.com/MoOx/reduce-css-calc/pull/25) - @andyjansson)
|
||||
|
||||
## 2.0.1 - 2017-05-08
|
||||
|
||||
- Fixed: Support for nested calc e.g. `calc(100% - calc(50px - 25px))`.
|
||||
- Fixed: Support for CSS variables e.g. `calc(var(--mouseX) * 1px)`.
|
||||
|
||||
## 2.0.0 - 2017-05-08
|
||||
|
||||
- Rewritten with a jison parser for more accurate value parsing.
|
||||
- Breaking: reduce-css-calc will now throw when trying to multiply or divide
|
||||
by the same unit (e.g. `calc(200px * 20px)`), and also when trying to divide
|
||||
by zero.
|
||||
- Added: Better handling of zero values (e.g. `calc(100vw / 2 - 6px + 0px)`
|
||||
becomes `calc(100vw / 2 - 6px)`).
|
||||
- Added: Better handling of mixed time values (e.g. `calc(1s - 50ms)`
|
||||
becomes `0.95s`).
|
||||
- Added: Inner parentheses calculation to simplify complex expressions (e.g.
|
||||
`calc(14px + 6 * ((100vw - 320px) / 448))` becomes `calc(9.71px + 1.34vw)`
|
||||
with precision set to `2`).
|
||||
- Fixed: `calc(1px + 1)` does not evaluate to `2px`.
|
||||
|
||||
([#22](https://github.com/MoOx/reduce-css-calc/pull/22) - @andyjansson)
|
||||
|
||||
## 1.3.0 - 2016-08-26
|
||||
|
||||
- Added: calc identifier from unresolved nested expressions are removed for
|
||||
better browser support
|
||||
([#19](https://github.com/MoOx/reduce-css-calc/pull/19) - @ben-eb)
|
||||
|
||||
## 1.2.8 - 2016-08-26
|
||||
|
||||
- Fixed: regression from 1.2.5 on calc() with value without leading 0
|
||||
([#17](https://github.com/MoOx/reduce-css-calc/pull/17) - @ben-eb)
|
||||
|
||||
## 1.2.7 - 2016-08-22
|
||||
|
||||
- Fixed: regression from 1.2.5 on calc() with value without leading 0
|
||||
(@MoOx)
|
||||
|
||||
## 1.2.6 - 2016-08-22
|
||||
|
||||
- Fixed: regression from 1.2.5 on calc() on multiple lines
|
||||
(@MoOx)
|
||||
|
||||
## 1.2.5 - 2016-08-22
|
||||
|
||||
- Fixed: security issue due to the usage of `eval()`.
|
||||
This is to avoid an arbitrary code execution.
|
||||
Now operations are resolved using
|
||||
[`math-expression-evaluator`](https://github.com/redhivesoftware/math-expression-evaluator)
|
||||
|
||||
## 1.2.4 - 2016-06-09
|
||||
|
||||
- Fixed: zero values are not unitless anymore.
|
||||
Browsers do not calculate calc() with 0 unitless values.

||||

|
||||
([#11](https://github.com/MoOx/reduce-css-calc/pull/11))
|
||||
|
||||
## 1.2.3 - 2016-04-28
|
||||
|
||||

|
||||
([#10](https://github.com/MoOx/reduce-css-calc/pull/10))
|
||||
|
||||
## 1.2.2 - 2016-04-19
|
||||
|
||||
- Fixed: Don't reduce expression containing CSS variables.
|
||||
([#9](https://github.com/MoOx/reduce-css-calc/pull/9))
|
||||
|
||||
## 1.2.1 - 2016-02-22
|
||||
|
||||

|
||||
([#8](https://github.com/MoOx/reduce-css-calc/pull/8))
|
||||
|
||||
## 1.2.0 - 2014-11-24
|
||||
|
||||
- Decimal precision is now customisable as the `precision` option
|
||||
|
||||
## 1.1.4 - 2014-11-12
|
||||
|
||||
- 5 decimals rounding for everything
|
||||
|
||||
## 1.1.3 - 2014-08-13
|
||||
|
||||
- 5 decimals rounding for percentage
|
||||
|
||||
## 1.1.2 - 2014-08-10
|
||||
|
||||
- Prevent infinite loop by adding a `Call stack overflow`
|
||||
- Correctly ignore unrecognized values (safer evaluation for nested expressions,
|
||||
see [postcss/postcss-calc#2](https://github.com/postcss/postcss-calc/issues/2))
|
||||
- Handle rounding issues (eg: 10% \* 20% now give 2%, not 2.0000000000000004%)
|
||||
|
||||
## 1.1.1 - 2014-08-06
|
||||
|
||||

||||
## 1.0.0 - 2014-08-04
|
||||
|

|
||||
- jscs + jshint added before tests

# reduce-css-calc
|
||||
|
||||
[](https://travis-ci.org/MoOx/reduce-css-calc)
|
||||
|
||||
> Reduce CSS calc() function to the maximum.
|
||||
|
||||
Particularly useful for packages like [rework-calc](https://github.com/reworkcss/rework-calc) or [postcss-calc](https://github.com/postcss/postcss-calc).
|
||||
|
||||
## Installation
|
||||
|
||||
```console
|
||||
npm install reduce-css-calc
|
||||
```
|
||||
|
||||
## Usage
|
||||
|
||||
### `var reducedString = reduceCSSCalc(string, precision)`
|
||||
|
||||
```javascript
|
||||
var reduceCSSCalc = require('reduce-css-calc')
|
||||
|
||||
reduceCSSCalc("calc(1 + 1)")
|
||||
// 2
|
||||
|
||||
reduceCSSCalc("calc((6 / 2) - (4 * 2) + 1)")
|
||||
// -4
|
||||
|
||||
reduceCSSCalc("calc(1/3)")
|
||||
// 0.33333
|
||||
|
||||
reduceCSSCalc("calc(1/3)", 10)
|
||||
// 0.3333333333
|
||||
|
||||
reduceCSSCalc("calc(3rem * 2 - 1rem)")
|
||||
// 5rem
|
||||
|
||||
reduceCSSCalc("calc(2 * 50%)")
|
||||
// 100%
|
||||
|
||||
reduceCSSCalc("calc(120% * 50%)")
|
||||
// 60%
|
||||
|
||||
reduceCSSCalc("a calc(1 + 1) b calc(1 - 1) c")
|
||||
// a 2 b 0 c
|
||||
|
||||
reduceCSSCalc("calc(calc(calc(1rem * 0.75) * 1.5) - 1rem)")
|
||||
// 0.125rem
|
||||
|
||||
reduceCSSCalc("calc(calc(calc(1rem * 0.75) * 1.5) - 1px)")
|
||||
// calc(1.125rem - 1px)
|
||||
|
||||
reduceCSSCalc("-moz-calc(100px / 2)")
|
||||
// 50px
|
||||
|
||||
reduceCSSCalc("-moz-calc(50% - 2em)")
|
||||
// -moz-calc(50% - 2em)
|
||||
```
|
||||

# postcss-value-parser
|
||||
|
||||
[](https://travis-ci.org/TrySound/postcss-value-parser)
|
||||
|
||||
Transforms CSS declaration values and at-rule parameters into a tree of nodes, and provides a simple traversal API.
|
||||
|
||||
## Usage
|
||||
|
||||
```js
|
||||
var valueParser = require('postcss-value-parser');
|
||||
var cssBackgroundValue = 'url(foo.png) no-repeat 40px 73%';
|
||||
var parsedValue = valueParser(cssBackgroundValue);
|
||||
// parsedValue exposes an API described below,
|
||||
// e.g. parsedValue.walk(..), parsedValue.toString(), etc.
|
||||
```
|
||||
|
||||
For example, parsing the value `rgba(233, 45, 66, .5)` will return the following:
|
||||
|
||||
```js
|
||||
{
|
||||
nodes: [
|
||||
{
|
||||
type: 'function',
|
||||
value: 'rgba',
|
||||
before: '',
|
||||
after: '',
|
||||
nodes: [
|
||||
{ type: 'word', value: '233' },
|
||||
{ type: 'div', value: ',', before: '', after: ' ' },
|
||||
{ type: 'word', value: '45' },
|
||||
{ type: 'div', value: ',', before: '', after: ' ' },
|
||||
{ type: 'word', value: '66' },
|
||||
{ type: 'div', value: ',', before: ' ', after: '' },
|
||||
{ type: 'word', value: '.5' }
|
||||
]
|
||||
}
|
||||
]
|
||||
}
|
||||
```
|
||||
|
||||
If you wanted to convert each `rgba()` value in `sourceCSS` to a hex value, you could do so like this:
|
||||
|
||||
```js
|
||||
var valueParser = require('postcss-value-parser');
|
||||
|
||||
var parsed = valueParser(sourceCSS);
|
||||
|
||||
// walk() will visit all the of the nodes in the tree,
|
||||
// invoking the callback for each.
|
||||
parsed.walk(function (node) {
|
||||
|
||||
// Since we only want to transform rgba() values,
|
||||
// we can ignore anything else.
|
||||
if (node.type !== 'function' && node.value !== 'rgba') return;
|
||||
|
||||
// We can make an array of the rgba() arguments to feed to a
|
||||
// convertToHex() function
|
||||
var color = node.nodes.filter(function (node) {
|
||||
return node.type === 'word';
|
||||
}).map(function (node) {
|
||||
return Number(node.value);
|
||||
}); // [233, 45, 66, .5]
|
||||
|
||||
// Now we will transform the existing rgba() function node
|
||||
// into a word node with the hex value
|
||||
node.type = 'word';
|
||||
node.value = convertToHex(color);
|
||||
})
|
||||
|
||||
parsed.toString(); // #E92D42
|
||||
```
|
||||
|
||||
## Nodes
|
||||
|
||||
Each node is an object with these common properties:
|
||||
|
||||
- **type**: The type of node (`word`, `string`, `div`, `space`, `comment`, or `function`).
|
||||
Each type is documented below.
|
||||
- **value**: Each node has a `value` property; but what exactly `value` means
|
||||
is specific to the node type. Details are documented for each type below.
|
||||
- **sourceIndex**: The starting index of the node within the original source
|
||||
string. For example, given the source string `10px 20px`, the `word` node
|
||||
whose value is `20px` will have a `sourceIndex` of `5`.
|
||||
|
||||
### word
|
||||
|
||||
The catch-all node type that includes keywords (e.g. `no-repeat`),
|
||||
quantities (e.g. `20px`, `75%`, `1.5`), and hex colors (e.g. `#e6e6e6`).
|
||||
|
||||
Node-specific properties:
|
||||
|
||||
- **value**: The "word" itself.
|
||||
|
||||
### string
|
||||
|
||||
A quoted string value, e.g. `"something"` in `content: "something";`.
|
||||
|
||||
Node-specific properties:
|
||||
|
||||
- **value**: The text content of the string.
|
||||
- **quote**: The quotation mark surrounding the string, either `"` or `'`.
|
||||
- **unclosed**: `true` if the string was not closed properly. e.g. `"unclosed string `.
|
||||
|
||||
### div
|
||||
|
||||
A divider, for example
|
||||
|
||||
- `,` in `animation-duration: 1s, 2s, 3s`
|
||||
- `/` in `border-radius: 10px / 23px`
|
||||
- `:` in `(min-width: 700px)`
|
||||
|
||||
Node-specific properties:
|
||||
|
||||
- **value**: The divider character. Either `,`, `/`, or `:` (see examples above).
|
||||
- **before**: Whitespace before the divider.
|
||||
- **after**: Whitespace after the divider.
|
||||
|
||||
### space
|
||||
|
||||
Whitespace used as a separator, e.g. ` ` occurring twice in `border: 1px solid black;`.
|
||||
|
||||
Node-specific properties:
|
||||
|
||||
- **value**: The whitespace itself.
|
||||
|
||||
### comment
|
||||
|
||||
A CSS comment starts with `/*` and ends with `*/`
|
||||
|
||||
Node-specific properties:
|
||||
|
||||
- **value**: The comment value without `/*` and `*/`
|
||||
- **unclosed**: `true` if the comment was not closed properly. e.g. `/* comment without an end `.
|
||||
|
||||
### function
|
||||
|
||||
A CSS function, e.g. `rgb(0,0,0)` or `url(foo.bar)`.
|
||||
|
||||
Function nodes have nodes nested within them: the function arguments.
|
||||
|
||||
Additional properties:
|
||||
|
||||
- **value**: The name of the function, e.g. `rgb` in `rgb(0,0,0)`.
|
||||
- **before**: Whitespace after the opening parenthesis and before the first argument,
|
||||
e.g. ` ` in `rgb( 0,0,0)`.
|
||||
- **after**: Whitespace before the closing parenthesis and after the last argument,
|
||||
e.g. ` ` in `rgb(0,0,0 )`.
|
||||
- **nodes**: More nodes representing the arguments to the function.
|
||||
- **unclosed**: `true` if the parentheses was not closed properly. e.g. `( unclosed-function `.
|
||||
|
||||
Media features surrounded by parentheses are considered functions with an
|
||||
empty value. For example, `(min-width: 700px)` parses to these nodes:
|
||||
|
||||
```js
|
||||
[
|
||||
{
|
||||
type: 'function', value: '', before: '', after: '',
|
||||
nodes: [
|
||||
{ type: 'word', value: 'min-width' },
|
||||
{ type: 'div', value: ':', before: '', after: ' ' },
|
||||
{ type: 'word', value: '700px' }
|
||||
]
|
||||
}
|
||||
]
|
||||
```
|
||||
|
||||
`url()` functions can be parsed a little bit differently depending on
|
||||
whether the first character in the argument is a quotation mark.
|
||||
|
||||
`url( /gfx/img/bg.jpg )` parses to:
|
||||
|
||||
```js
|
||||
{ type: 'function', sourceIndex: 0, value: 'url', before: ' ', after: ' ', nodes: [
|
||||
{ type: 'word', sourceIndex: 5, value: '/gfx/img/bg.jpg' }
|
||||
] }
|
||||
```
|
||||
|
||||
`url( "/gfx/img/bg.jpg" )`, on the other hand, parses to:
|
||||
|
||||
```js
|
||||
{ type: 'function', sourceIndex: 0, value: 'url', before: ' ', after: ' ', nodes: [
|

type: 'string', sourceIndex: 5, quote: '"', value: '/gfx/img/bg.jpg' },

|

```
|
||||
|
||||
## API
|
||||
|
||||
```
|
||||
var valueParser = require('postcss-value-parser');
|
||||
```
|
||||
|
||||
### valueParser.unit(quantity)
|
||||
|
||||
Parses `quantity`, distinguishing the number from the unit. Returns an object like the following:
|
||||
|
||||
```js
|
||||
// Given 2rem
|
||||
{
|
||||
number: '2',
|
||||
unit: 'rem'
|
||||
}
|
||||
```
|
||||
|
||||
If the `quantity` argument cannot be parsed as a number, returns `false`.
|
||||
|
||||
*This function does not parse complete values*: you cannot pass it `1px solid black` and expect `px` as
|
||||
the unit. Instead, you should pass it single quantities only. Parse `1px solid black`, then pass it
|
||||
the stringified `1px` node (a `word` node) to parse the number and unit.
|
||||
|
||||
### valueParser.stringify(nodes[, custom])
|
||||
|
||||
Stringifies a node or array of nodes.
|
||||
|
||||
The `custom` function is called for each `node`; return a string to override the default behaviour.
|
||||
|
||||
### valueParser.walk(nodes, callback[, bubble])
|
||||
|
||||
Walks each provided node, recursively walking all descendent nodes within functions.
|
||||
|
||||
Returning `false` in the `callback` will prevent traversal of descendent nodes (within functions).
|
||||
You can use this feature to for shallow iteration, walking over only the *immediate* children.
|
||||
*Note: This only applies if `bubble` is `false` (which is the default).*
|
||||
|
||||
By default, the tree is walked from the outermost node inwards.
|
||||
To reverse the direction, pass `true` for the `bubble` argument.
|
||||
|
||||
The `callback` is invoked with three arguments: `callback(node, index, nodes)`.
|
||||
|
||||
- `node`: The current node.
|
||||
- `index`: The index of the current node.
|
||||
- `nodes`: The complete nodes array passed to `walk()`.
|
||||
|
||||
Returns the `valueParser` instance.
|
||||
|
||||
### var parsed = valueParser(value)
|
||||
|
||||
Returns the parsed node tree.
|
||||
|
||||
### parsed.nodes
|
||||
|
||||
The array of nodes.
|
||||
|
||||
### parsed.toString()
|
||||
|
||||
Stringifies the node tree.
|
||||
|
||||
### parsed.walk(callback[, bubble])
|
||||
|
||||
Walks each node inside `parsed.nodes`. See the documentation for `valueParser.walk()` above.
