/**
|
|
* Parse the plugin contents to retrieve plugin's metadata.
|
|
*
|
|
* The metadata of the plugin's data searches for the following in the plugin's
|
|
* header. All plugin data must be on its own line. For plugin description, it
|
|
* must not have any newlines or only parts of the description will be displayed
|
|
* and the same goes for the plugin data. The below is formatted for printing.
|
|
*
|
|
* <code>
|
|
* /*
|
|
* Plugin Name: Name of Plugin
|
|
* Plugin URI: Link to plugin information
|
|
* Description: Plugin Description
|
|
* Author: Plugin author's name
|
|
* Author URI: Link to the author's web site
|
|
* Version: Must be set in the plugin for WordPress 2.3+
|
|
* Text Domain: Optional. Unique identifier, should be same as the one used in
|
|
* plugin_text_domain()
|
|
* Domain Path: Optional. Only useful if the translations are located in a
|
|
* folder above the plugin's base path. For example, if .mo files are
|
|
* located in the locale folder then Domain Path will be "/locale/" and
|
|
* must have the first slash. Defaults to the base folder the plugin is
|
|
* located in.
|
|
* * / # Remove the space to close comment
|
|
* </code>
|
|
*
|
|
* Plugin data returned array contains the following:
|
|
* 'Name' - Name of the plugin, must be unique.
|
|
* 'Title' - Title of the plugin and the link to the plugin's web site.
|
|
* 'Description' - Description of what the plugin does and/or notes
|
|
* from the author.
|
|
* 'Author' - The author's name
|
|
* 'AuthorURI' - The authors web site address.
|
|
* 'Version' - The plugin version number.
|
|
* 'PluginURI' - Plugin web site address.
|
|
* 'TextDomain' - Plugin's text domain for localization.
|
|
* 'DomainPath' - Plugin's relative directory path to .mo files.
|
|
*
|
|
* Some users have issues with opening large files and manipulating the contents
|
|
* for want is usually the first 1kiB or 2kiB. This function stops pulling in
|
|
* the plugin contents when it has all of the required plugin data.
|
|
*
|
|
* The first 8kiB of the file will be pulled in and if the plugin data is not
|
|
* within that first 8kiB, then the plugin author should correct their plugin
|
|
* and move the plugin data headers to the top.
|
|
*
|
|
* The plugin file is assumed to have permissions to allow for scripts to read
|
|
* the file. This is not checked however and the file is only opened for
|
|
* reading.
