This plugin requires Grunt.
If you haven't used Grunt before, be sure to check out the Getting Started guide, as it explains how to create a Gruntfile as well as install and use Grunt plugins. Once you're familiar with that process, you may install this plugin with this command:
npm install grunt-regex-extract --save-dev
Once the plugin has been installed, it may be enabled inside your Gruntfile with this line of JavaScript:
grunt.loadNpmTasks('grunt-regex-extract');
In your project's Gruntfile, add a section named regex_extract to the data object passed into grunt.initConfig().
grunt.initConfig({
regex_extract: {
options: {
// Task-specific options go here.
},
your_target: {
// Target-specific file lists and/or options go here.
},
},
})
Type: String
Default value: '(.*|\n*)'
A string value that represents the regular expression to use.
Type: String
Default value: 'ig'
A string value that determines which JavaScript RegExp modifiers to use (such as 'i' and 'g')
Type: String
Default value: '1'
A comma separated list of match points to determine what part of the regex you want to extract. Note: starts with 1
Type: boolean
Default value: 'true'
A boolean value that determines whether the path of the file is to be included in the destination file
<!DOCTYPE html>
<html>
<head>
<meta charset="ISO-8859-1">
<title>Hello World</title>
<script type="text/javascript" src="/js/header-js-one.js"></script>
</head>
<header>
</header>
<body>
<h1>Hello World!</h1>
<p>Foo Bar :)</p>
</body>
<footer>
<script type="text/javascript" src="/js/footer-js-one.js"></script>
<Script type="text/javascript" src="/js/footer-js-two.js"></script>
<script type="text/javascript">
var inlineFooterJsVar = "foo";
</script>
</footer>
</html>
In this example, the default options are applied but only the regex option is explicitly passed.
grunt.initConfig({
regex_extract: {
default_options: {
options: {
regex : "<script(.*|\n*)>(\s*|\n*)<\/script>"
},
files: {
'test/actual/default_options.txt': ['test/fixtures/example.html']
}
}
},
})
test/fixtures/example.html,type="text/javascript" src="/js/header-js-one.js"
test/fixtures/example.html,type="text/javascript" src="/js/footer-js-one.js"
test/fixtures/example.html,type="text/javascript" src="/js/footer-js-two.js"
In this example, all the default options are overridden
grunt.initConfig({
regex_extract: {
default_options: {
options: {
regex : "<script(.*|\n*)>(\s*|\n*)<\/(\s*|\n*)>",
modifiers: "g",
matchPoints: "1,3",
includePath : false
},
files: {
'test/actual/default_options.txt': ['test/fixtures/example.html']
}
}
},
})
type="text/javascript" src="/js/header-js-one.js",script
type="text/javascript" src="/js/footer-js-one.js",script
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.
