◆ __construct()

ResourceLoaderImageModule::__construct (   $options = [],
  $localBasePath = null 
)

Constructs a new module from an options array.

Parameters
array$optionsList of options; if not given or empty, an empty module will be constructed
string | null$localBasePathBase path to prepend to all local paths in $options. Defaults to $IP

Below is a description for the $options array:

Construction options:
[
// Base path to prepend to all local paths in $options. Defaults to $IP
'localBasePath' => [base path],
// Path to JSON file that contains any of the settings below
'data' => [file path string]
// CSS class prefix to use in all style rules
'prefix' => [CSS class prefix],
// Alternatively: Format of CSS selector to use in all style rules
'selector' => [CSS selector template, variables: {prefix} {name} {variant}],
// Alternatively: When using variants
'selectorWithoutVariant' => [CSS selector template, variables: {prefix} {name}],
'selectorWithVariant' => [CSS selector template, variables: {prefix} {name} {variant}],
// List of variants that may be used for the image files
'variants' => [
// This level of nesting can be omitted if you use the same images for every skin
[skin name (or 'default')] => [
[variant name] => [
'color' => [color string, e.g. '#ffff00'],
'global' => [boolean, if true, this variant is available
for all images of this type],
],
...
],
...
],
// List of image files and their options
'images' => [
// This level of nesting can be omitted if you use the same images for every skin
[skin name (or 'default')] => [
[icon name] => [
'file' => [file path string or array whose values are file path strings
and whose keys are 'default', 'ltr', 'rtl', a single
'en,de,ar'],
'variants' => [array of variant name strings, variants
available for this image],

Using a hook running we can avoid having all this option specific stuff in our mainline code Using the function We ve cleaned up the code here by removing clumps of infrequently used code and moving them off somewhere else It s much easier for someone working with this code to see what s _really_ going and make changes or fix bugs In we can take all the code that deals with the little used title reversing we can concentrate it all in an extension file
