'**/*.html'
],
patterns: [
{
match: 'foo',

}
]
});
```

patterns: [
{
match: 'version',

},
{
match: 'timestamp',
replacement: Date.now()

### Cache busting

```html
```
Brocfile.js:
```javascript
var BroccoliReplace = require('broccoli-replace');
module.exports = new BroccoliReplace('src', {
files: [
'index.html'
],
patterns: [
{
match: 'timestamp',
replacement: Date.now()
}
]
});
```
### Include file
File `src/index.html`:
```html
@@include
```
Brocfile.js:
```javascript
var BroccoliReplace = require('broccoli-replace');
var fs = require('fs');
module.exports = new BroccoliReplace('src', {
files: [
'index.html'
],
patterns: [
{
match: 'include',
replacement: fs.readFileSync('./includes/content.html', 'utf8')
}
]
});
```
### Regular expression
File `src/username.txt`:
```
John Smith
```
Brocfile.js:
```javascript
var BroccoliReplace = require('broccoli-replace');
module.exports = new BroccoliReplace('src', {
files: [
'username.txt'
],
patterns: [
{
match: /(\w+)\s(\w+)/,
replacement: '$2, $1' // Replaces "John Smith" with "Smith, John"
}
]
});
```
### Lookup for `foo` instead of `@@foo`
Brocfile.js:
```javascript
var BroccoliMergeTrees = require('broccoli-merge-trees');
var BroccoliReplace = require('broccoli-replace');
var inputNodes = [
new BroccoliReplace('src', {
files: [
'foo.txt'
],
patterns: [
{
match: /foo/g, // Explicitly using a regexp
replacement: 'bar'
}
]
}),
new BroccoliReplace('src', {
files: [
'foo.txt'
],
patterns: [
{
match: 'foo',
replacement: 'bar'
}
],
usePrefix: false // Using the option provided
}),
new BroccoliReplace('src', {
files: [
'foo.txt'
],
patterns: [
{
match: 'foo',
replacement: 'bar'
}
],
prefix: '' // Removing the prefix manually
})
];
module.exports = new BroccoliMergeTrees(nodes);
```
