    broccoli-replace Build Status NPM Version

    Replace text patterns with applause.

    Install

    From NPM:

    npm install broccoli-replace --save-dev

    Replace Filter

    Assuming installation via NPM, you can use broccoli-replace in your Brocfile.js like this:

    var replace = require('broccoli-replace');
    module.exports = replace('src', {
      files: [
        '**/*.html' // replace only html files in src
      ],
      patterns: [
        {
          match: 'foo',
          replacement: 'bar'
        }
      ]
    });

    Options

    files

    Type: Array Default: []

    Define the source files that will be used for replacements, you can use globbing via minimatch library.

    This is a mandatory value, an empty definition will ignore any kind of replacement.

    patterns

    Type: Array

    Define patterns that will be used to replace the contents of source files.

    patterns.match

    Type: String|RegExp

    Indicates the matching expression.

    If matching type is String we use a simple variable lookup mechanism @@string (in any other case we use the default regexp replace logic):

    {
      patterns: [
        {
          match: 'foo',
          replacement: 'bar'  // replaces "@@foo" to "bar"
        }
      ]
    }

    patterns.replacement or patterns.replace

    Type: String|Function|Object

    Indicates the replacement for match, for more information about replacement check out the String.replace.

    You can specify a function as replacement. In this case, the function will be invoked after the match has been performed. The function's result (return value) will be used as the replacement string.

    {
      patterns: [
        {
          match: /foo/g,
          replacement: function () {
            return 'bar'; // replaces "foo" to "bar"
          }
        }
      ]
    }

    Also supports object as replacement (we create string representation of object using JSON.stringify):

    {
      patterns: [
        {
          match: /foo/g,
          replacement: [1, 2, 3] // replaces "foo" with string representation of "array" object
        }
      ]
    }

    The replacement only resolve the special replacement patterns when using regexp for matching.

    patterns.json

    Type: Object

    If an attribute json is found in pattern definition we flatten the object using delimiter concatenation and each key–value pair will be used for the replacement (simple variable lookup mechanism and no regexp support).

    {
      patterns: [
        {
          json: {
            "key": "value" // replaces "@@key" to "value"
          }
        }
      ]
    }

    Also supports nested objects:

    {
      patterns: [
        {
          json: {
            "key": "value",   // replaces "@@key" to "value"
            "inner": {        // replaces "@@inner" with string representation of "inner" object
              "key": "value"  // replaces "@@inner.key" to "value"
            }
          }
        }
      ]
    }

    For deferred invocations is possible to define functions:

    {
      patterns: [
        {
          json: function (done) {
            done({
              key: 'value'
            });
          }
        }
      ]
    }

    patterns.yaml

    Type: String

    If an attribute yaml found in pattern definition it will be converted and then processed like json attribute.

    {
      patterns: [
        {
          yaml: 'key: value'  // replaces "@@key" to "value"
        }
      ]
    }

    For deferred invocations is possible to define functions:

    {
      patterns: [
        {
          yaml: function (done) {
            done('key: value');
          }
        }
      ]
    }

    patterns.cson

    Type: String

    If an attribute cson is found in pattern definition it will be converted and then processed like json attribute.

    {
      patterns: [
        {
          cson: 'key: \'value\''
        }
      ]
    }

    For deferred invocations is possible to define functions:

    {
      patterns: [
        {
          cson: function (done) {
            done('key: \'value\'');
          }
        }
      ]
    }

    variables

    Type: Object

    This is the old way to define patterns using plain object (simple variable lookup mechanism and no regexp support). You can still use this but for more control you should use the new patterns way.

    {
      variables: {
        'key': 'value' // replaces "@@key" to "value"
      }
    }

    prefix

    Type: String Default: @@

    The prefix added for matching (prevent bad replacements / easy way).

    This only applies for simple variable lookup mechanism.

    usePrefix

    Type: Boolean Default: true

    If set to false, we match the pattern without prefix concatenation (useful when you want to lookup a simple string).

    This only applies for simple variable lookup mechanism.

    preservePrefix

    Type: Boolean Default: false

    If set to true, we preserve the prefix in target.

    This only applies for simple variable lookup mechanism and when patterns.replacement is a string.

    delimiter

    Type: String Default: .

    The delimiter used to flatten when using object as replacement.

    preserveOrder

    Type: Boolean Default: false

    If set to true, we preserve the patterns definition order, otherwise these will be sorted (in ascending order) to prevent replacement issues like head / header (typo regexps will be resolved at last).

    Usage Examples

    Basic

    File src/manifest.appcache:

    CACHE MANIFEST
    # @@timestamp
    
    CACHE:
    
    favicon.ico
    index.html
    
    NETWORK:
    *
    

    Brocfile.js:

    var replace = require('broccoli-replace');
    module.exports = replace('src', {
      files: [
        'manifest.appcache'
      ],
      patterns: [
        {
          match: 'timestamp',
          replacement: new Date().getTime()
        }
      ]
    });

    Multiple matching

    File src/manifest.appcache:

    CACHE MANIFEST
    # @@timestamp
    
    CACHE:
    
    favicon.ico
    index.html
    
    NETWORK:
    *
    

    File src/humans.txt:

                  __     _
       _    _/__  /./|,//_`
      /_//_// /_|///  //_, outaTiME v.@@version

    Brocfile.js:

    var pkg = require('./package.json');
    var replace = require('broccoli-replace');
    module.exports = replace('src', {
      files: [
        'manifest.appcache',
        'humans.txt'
      ],
      patterns: [

        {
          match: 'timestamp',
          replacement: new Date().getTime()
        }
      ]
    });

    Cache busting

    File src/index.html:

    <head>
      <link rel="stylesheet" href="/css/style.css?rel=@@timestamp">
      <script src="/js/app.js?rel=@@timestamp"></script> 
    </head>

    Brocfile.js:

    var replace = require('broccoli-replace');
    module.exports = replace('src', {
      files: [
        'index.html'
      ],
      patterns: [
        {
          match: 'timestamp',
          replacement: new Date().getTime()
        }
      ]
    });

    Include file

    File src/index.html:

    <body>
      @@include
    </body>

    Brocfile.js:

    var fs = require('fs');
    var replace = require('broccoli-replace');
    module.exports = replace('src', {
      files: [
        'index.html'
      ],
      patterns: [
        {
          match: 'include',
          replacement: fs.readFileSync('./includes/content.html', 'utf8')
        }
      ]
    });

    Regular expression

    File src/username.txt:

    John Smith
    

    Brocfile.js:

    var replace = require('broccoli-replace');
    module.exports = replace('src', {
      files: [
        'username.txt'
      ],
      patterns: [
        {
          match: /(\w+)\s(\w+)/,
          replacement: '$2, $1' // replaces "John Smith" to "Smith, John"
        }
      ]
    });

    Lookup for foo instead of @@foo

    Brocfile.js:

    var mergeTrees = require('broccoli-merge-trees');
    var replace = require('broccoli-replace');
     
    // option 1 (explicitly using an regexp)
    var replacer_op1 = replace('src_op1', {
      files: [
        'foo.txt'
      ],
      patterns: [
        {
          match: /foo/g,
          replacement: 'bar'
        }
      ]
    });
     
    // option 2 (easy way)
    var replacer_op2 = replace('src_op2', {
      files: [
        'foo.txt'
      ],
      patterns: [
        {
          match: 'foo',
          replacement: 'bar'
        }
      ],
      usePrefix: false
    });
     
    // option 3 (old way)
    var replacer_op3 = replace('src_op3', {
      files: [
        'foo.txt'
      ],
      patterns: [
        {
          match: 'foo',
          replacement: 'bar'
        }
      ],
      prefix: '' // remove prefix
    });
     
    module.exports = mergeTrees([replacer_op1, replacer_op2, replacer_op3]);
