Grunt plugin to search and replace text content of files based on regular expression patterns
## Getting Started
Install this grunt plugin next to your project's [grunt.js gruntfile][getting_started] with:
```
npm install --save-dev grunt-regex-replace
```
Then add this line to your project's `grunt.js` gruntfile:
```javascript
grunt.loadNpmTasks('grunt-regex-replace');
```
[grunt]: http://gruntjs.com/
[getting_started]: https://github.com/gruntjs/grunt/blob/master/docs/getting_started.md
## How to use
Here is a sample of the definition within the object passed to grunt.initConfig
###Sample Code
"regex-replace": {
foofoo: { //specify a target with any name
src: ['foo/bar.js'],
actions: [
{
name: 'bar',
search: '(^|\\s)console.log',
replace: '//console.log',
flags: 'g'
},{
name: 'foo',
search: 'var v = \'[^\']*\';',
replace: 'var v = \'<%= pkg.release.version_code %>\';',
flags: ''
},{
name: 'foobar',
search: new RegExp('\\w+'),
replace: function() {
return 'foofoo';
}
},{
name: 'baz',
use: function(data) {
return data.sourceContent.length > 3;
},
search: 'abc',
replace: 'abcde'
}
]
}
}
### src property
Takes the path to the files relative to the grunt file, it accepts strings as well as an array of file paths.
Also supports templates, e.g
src: 'customisation/*.js',
src: '**/*.js',
src: ['foo/bar.js','foo/foo.js'],
src: ['<%= pkg.id %>/bar.js', 'foo/foo.js']
### dest property
Takes a file path string or an array of file paths that match the src paths. If a `dest` file is specified for the corresponding
`src` file, the `src` file remains unchanged and the changes are applied to the `dest` file. e.g
1) `bla.js` will not be overwritten but `foo.js` will contain the new changes.
```
{
src: ['bla.js'],
dest: 'foo.js'
}
```
2) `bla.js` and `foo.js` will be affected as above. `baz.js` will be overwritten.
```
{
src: ['bla.js', 'baz.js'],
dest: ['foo.js']
}
```
3) `bla.js` and `foo.js` will be affected as above. `baz.js` will be ignored.
```
{
src: ['bla.js'],
dest: ['foo.js', 'baz.js']
}
```
### actions property (array | function)
Accepts an array of objects or a function (which returns an array of objects) representing the actions to take place. Each action contains an optional `name` property, an optional `use` property, a `search` property, a `replace` property and
an optional `flags` property. Here are some examples of the object.
{
name: 'foo',
use: function(data) {
return data.file.indexOf('.skip') === -1 && data.sourceContent.indexOf('console.log') > -1;
}, //also accepts a template string or any value
search: '(^|\\s)console.log',
replace: '//console.log',
flags: 'gi'
}
{
name: 'bar',
search: /\\w+/g, //also accepts new RegExp()
replace: function() {
return 'foo';
}
}
#### name property
A string value.
#### use property (function | template string | value)
*Default*: `true`
Used to determine whether the corresponding action should be executed or not. If set to `true` the action executes,
if `false` it does not. Can also be a function which returns a value, a template string producing a value.
It enables specifying the conditions for when actions are used.
An object with the following fields is passed in test function:
* `file` - path to a file that is being processed;
* `sourceContent` - source contents of the processed file;
* `updatedContent` - contents of the file after previously applied actions;
* `action` - object that is representing options of the current action;
* `task` - reference to the corresponding task;
* `grunt` - reference to grunt.
#### search property (regexp | substr)
A regular expression string or object defining the text content to be found.
#### replace property (substr | function)
A string / regular expression pattern or function to replace the text content.
For the replace function, values that match the parenthesized substring matches are passed as arguments
```
{
search: new RegExp(/(\w+)\s(\w+)/),
replace: function(arg1, arg2, ... argN) {
// arg1 is the full string matched
// arg2 is the first parenthesized substring match
// argN is the Nth parenthesized substring match
}
}
```
See [MDN Documentation](https://developer.mozilla.org/en/docs/Web/JavaScript/Guide/Regular_Expressions#Using_parenthesized_substring_matches) for details on "using parenthesized substring matches."
#### flags property
Regular expressions options (ie `gmi`). If the flags property is not defined, and the search property is a string, it defaults to `'g'`. To specify no options, set the flags to empty string (ie flags : '').
Note: Do not use the `flags` property if a `regexp` was used for the search property. Instead, use the flag(s) in your regex. ie: `/^[a-z0-9_-]{6,18}$/g`
#### debug log
specify `--verbose` as a command-line option to show detailed logs
## Contributing
In lieu of a formal styleguide, take care to maintain the existing coding style. Add unit tests for any new or changed functionality. Lint and test your code using [grunt][grunt].
