grunt-phpclassmap

Generate PHP classmaps

Getting Started

This plugin requires Grunt ~0.4.4

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-phpclassmap --save-dev

Once the plugin has been installed, it may be enabled inside your Gruntfile with this line of JavaScript:

grunt.loadNpmTasks('grunt-phpclassmap');

The "phpclassmap" task

Overview

In your project's Gruntfile, add a section named phpclassmap to the data object passed into grunt.initConfig().

grunt.initConfig({
  phpclassmap: {
    options: {
      // Task-specific options go here.
    },
    your_target: {
      // Target-specific file lists and/or options go here.
    },
  },
});

Options

options.basedir

Type: String Default value: .

Base directory from which to create the relative paths to class files, defaults to process.cwd.

options.phpbin

Type: String Default value: 'php'

Path to the php executable

options.quote_path

Type: Boolean Default value: true

Wether or not the classes in the classmap should be quoted. There might be some situations where you don't want to do that, for instance in the filter example.

options.dest

Type: String Default value: none

Where to write the classmap file to.

options.map

Type: Function Default value: none

Function which maps the entry inside the destination classmap file. The function recieves a item object which in turn has the following properties:

absolute_path (absolute path to the object)
relative_path (relative path to the object, which is the absolute_path without the basedir option)
name (name of the object)
type (class, interface, trait)

IMPORTANT The function should return the resulting item

options.filter

Type: Function Default value: none

Function which can be used to filter out unwanted items for the classmap, see the filter example

options.sort

Type: Function Default value: none

Function which allows you to sort the found classes by providing a function which will be used by the Array.prototype.sort function, see the sort example

Usage Examples

Basic usage

The following is a basic example usage of the grunt-phpclassmap. This will scan all files under the directory src and will try to find all php classes.

grunt.initConfig({
    phpclassmap: {
        options: {
            dest: './classmap.php'
        },
        files  : {
            src   : [ 'src/**/*.php' ],
            expand: true
        }
    },
});

The resulting classmap.php will look something like:

<?php
/**
 * Generated by grunt-phpclassmap on {{date}}
 */
return array(
	"Foo" => "/src/foo.class.php",
	"Bar" => "/src/class-bar.php"
);

/* EOF */

Map items to use a defined constant

In this example, we use override the format function in order to use a defined constant inside the resulting classmap

grunt.initConfig({
    phpclassmap: {
        options: {
			quote_path: false,
            dest: './classmap.php',
            map: function(item) {
                item.relative_path = 'DEFINED_BASE_PATH_CONSTANT . "' + item.relative_path + '"';
                return item;
            }
        },
        files  : {
            src   : [ 'classes/**/*.php' ],
            expand: true
        }
    },
});

Custom handlebars template

grunt-phpclassmap uses handlebars to render the classmap file, you can specify a custom handlebars template, like so:

grunt.initConfig({
    phpclassmap: {
        options: {
            dest: './classmap.php',
            template: 'my-classmap-template.tpl'
        },
        files  : {
            src   : [ 'classes/**/*.php' ],
            expand: true
        }
    },
});

currenty the compiled template recieves data in the form:

{
	quote_path: Boolean,
    items: Array,
    date: String
}

Custom the render functionality

besides changing the template it's also possible to define you own render function, like so:

grunt.initConfig({
    phpclassmap: {
        options: {
            dest: './classmap.php',
            render: function(objects, cb) {
                var content = '<?php\n' +
                    'return array(' +
                    '%items%' +
                    ');';
                // Build up the item array
                var items = [];
                for(var i=0; i<objects.length;i++) {
                    items.push('"' + objects[i].name + '" => "' + objects[i].absolute_path + '"');
                }
                cb(content.replace('%items%', items.join(',')));
            }
        },
        files  : {
            src   : [ 'classes/**/*.php' ],
            expand: true
        }
    },
});

IMPORTANT: When you override the render method be sure to call to callback which is provided to the function, as this is the function which writes to results to the classmap.

Custom map and render functionality

In this example you can see how you can mix the map and render function to do some custom stuff. Note that the map allows you to add additional data, which is written in de render function. This could have also been done by providing a custom template.

grunt.initConfig({
    phpclassmap: {
        options: {
            map: function (item) {
                item.rewritten_path = your_rewrite_function(item);
                return item;
            },
            render: function(objects, cb) {
                    var content = '<?php\n' +
                                'return array(' +
                                '%items%' +
                                ');';
                    // Build up the item array
                    var items = [];
                    for(var i=0; i<objects.length;i++) {
                        items.push('"' + objects[i].name + '" => "' + objects[i].rewritten_path) + '"';
                    }
            cb(content.replace('%items%', items.join(',')));
        }

Filter example

The filter option can be used to remove unwanted items, the function should return a Boolean. It should return true to include the item in the classmap; otherwise, false.

grunt.initConfig({
    phpclassmap: {
        options: {
			dest: 'classmap.php',
            filter: function (item) {
                return item.name != 'My_Unwanted_Class';
            }
        }
	}
});

Sort example

The sort option can be used to sort the objects before they are written to the classmap file.

grunt.initConfig({
    phpclassmap: {
		options: {
			dest: './classmap.php',
			sort: function(a, b) {
				var aa = a.name.toUpperCase();
				var bb = b.name.toUpperCase();
				return (aa < bb) ? -1 : (aa > bb) ? 1 : 0;
			}
		},
		files  : {
            src   : [ 'src/**/*.php' ],
            expand: true
        }
	}
}

Combined with grunt-contrib-watch

Example of a nice way to automaticly generate classmaps during development.

grunt.initConfig({
    phpclassmap: {
        options: {
			dest: 'classmap.php',
            filter: function (item) {
                return item.name != 'My_Unwanted_Class';
            }
        },
		files  : {
            src   : [ 'classes/**/*.php' ],
            expand: true
        }
	},
	watch: {
		phpclassmap: {
			files: ['classes/**/*.php' ],
			tasks: [ 'phpclassmap' ]
		}
	}
});
