|
|
## Installation
|
|
|
|
npm install pug-attrs
|
|
|
|
## Usage
|
|
|
|
```js
|
|
var compileAttrs = require('pug-attrs');
|
|
```
|
|
|
|
### `compileAttrs(attrs, options)`
|
|
|
|
Compile `attrs` to a JavaScript string that evaluates to the attributes in the desired format.
|
|
|
|
`options` MUST include the following properties:
|
|
|
|
- `terse`: whether or not to use HTML5-style terse boolean attributes
|
|
- `runtime`: callback that takes a runtime function name and returns the source code that will evaluate to that function at runtime
|
|
- `format`: output format; must be `html` or `object`
|
|
|
|
`attrs` is an array of attributes, with each attribute having the form of `{ name, val, mustEscape }`. `val` represents a JavaScript string that evaluates to the value of the attribute, either statically or dynamically.
|
|
|
|
```js
|
|
var compileAttrs = require('pug-attrs');
|
|
var pugRuntime = require('pug-runtime');
|
|
|
|
function getBaz () { return 'baz<>'; }
|
|
|
|
var attrs = [
|
|
{name: 'foo', val: '"bar"', mustEscape: true },
|
|
{name: 'baz', val: 'getBaz()', mustEscape: true },
|
|
{name: 'quux', val: true, mustEscape: false}
|
|
];
|
|
var result, finalResult;
|
|
|
|
// HTML MODE
|
|
result = compileAttrs(attrs, {
|
|
terse: true,
|
|
format: 'html',
|
|
runtime: function (name) { return 'pugRuntime.' + name; }
|
|
});
|
|
//=> '" foo=\\"bar\\"" + pugRuntime.attr("baz", getBaz(), true, true) + " quux"'
|
|
|
|
finalResult = Function('pugRuntime, getBaz',
|
|
'return (' + result + ');'
|
|
);
|
|
finalResult(pugRuntime, getBaz);
|
|
// => ' foo="bar" baz="baz<>" quux'
|
|
|
|
// OBJECT MODE
|
|
result = compileAttrs(attrs, {
|
|
terse: true,
|
|
format: 'object',
|
|
runtime: function (name) { return 'pugRuntime.' + name; }
|
|
});
|
|
//=> '{"foo": "bar","baz": pugRuntime.escape(getBaz()),"quux": true}'
|
|
|
|
finalResult = Function('pugRuntime, getBaz',
|
|
'return (' + result + ');'
|
|
);
|
|
finalResult(pugRuntime, getBaz);
|
|
//=> { foo: 'bar', baz: 'baz<>', quux: true }
|
|
