reduce-by-delimited

Reduces a string contents by delimiter and returns the difference and the extracted delimited content.

General Usage:

This module is good for non nested delimited content extraction as shown below:

    // some-file.html
    <!-- :someMadeUpDelimAndFormat -->
    
        ... The goods go here ...
        
    <!-- :/someMadeUpDelimAndFormat -->
    
        ... Other content here ...
        
    <script>
        ... some content here ...
    </script>
    
    <style>
        ... some content here ...
    </style>
    

But not good for:

    <!-- #otherMadeUpDelim -->
        <!-- #otherMadeUpDelim -->
            <!-- otherMadeUpDelim -->
                ... Some content here ...
            <!-- /otherMadeUpDelim -->
        <!-- /otherMadeUpDelim -->
    <!-- /otherMadeUpDelim -->
    
    <!-- Here the first open delimiter and the first closing delimiter will be used as a block (module doesn't handle nested 
    delimited content) -->

Install:

npm install reduce-by-delimited or npm install elycruz/reduce-by-delimited

Interface:

reduceByDelimited (content, openingDelim, closingDelim, keepDelimInExtracted, minContentLen, aggregator)

Reduces the content passed in by any content that has been delimited by openingDelim and closingDelim.

Note: Method is curried up to an arity of three by default.

Params:

• content {String}
• openingDelim {String}
• closingDelim {String}
• keepDelimInExtracted {Boolean=false}
• minContentLen {Number=1}
• aggregator {Object={}}

Returns:

{difference: {String}, extracted: {Array}}

Usage:

var openDelim = '<!-- someDelimiter -->',
    closeDelim = '<!-- /someDelimiter -->',
    content = 
    `
        <!-- someDelimiter -->
        <meta charset="UTF-8">
        <title>Example Body Content</title>
        <meta name="description" content="Example Body Content's meta-description here." />
        <link rel="stylesheet" href="some-style-sheet-dot-css-here.css" />
        <!-- /someDelimiter -->
        
        <p>Other content here</p>
    `;
    result = rbd.reduceByDelimited(content, openDelim, closeDelim);
    
    result.difference === `
    
        <p>Other content here</p>
    ` // true
    
    result.extracted[0] === `
        <meta charset="UTF-8">
        <title>Example Body Content</title>
        <meta name="description" content="Example Body Content's meta-description here." />
        <link rel="stylesheet" href="some-style-sheet-dot-css-here.css" />
    ` // true
