| 10 | * Parse the plugin contents to retrieve plugin's metadata. |
| 11 | * |
| 12 | * The metadata of the plugin's data searches for the following in the plugin's |
| 13 | * header. All plugin data must be on its own line. For plugin description, it |
| 14 | * must not have any newlines or only parts of the description will be displayed |
| 15 | * and the same goes for the plugin data. The below is formatted for printing. |
| 16 | * |
| 17 | * <code> |
| 18 | * /* |
| 19 | * Plugin Name: Name of Plugin |
| 20 | * Plugin URI: Link to plugin information |
| 21 | * Description: Plugin Description |
| 22 | * Author: Plugin author's name |
| 23 | * Author URI: Link to the author's web site |
| 24 | * Version: Must be set in the plugin for WordPress 2.3+ |
| 25 | * Text Domain: Optional. Unique identifier, should be same as the one used in |
| 26 | * plugin_text_domain() |
| 27 | * Domain Path: Optional. Only useful if the translations are located in a |
| 28 | * folder above the plugin's base path. For example, if .mo files are |
| 29 | * located in the locale folder then Domain Path will be "/locale/" and |
| 30 | * must have the first slash. Defaults to the base folder the plugin is |
| 31 | * located in. |
| 32 | * * / # Remove the space to close comment |
| 33 | * </code> |
| 34 | * |
| 35 | * Plugin data returned array contains the following: |
| 36 | * 'Name' - Name of the plugin, must be unique. |
| 37 | * 'Title' - Title of the plugin and the link to the plugin's web site. |
| 38 | * 'Description' - Description of what the plugin does and/or notes |
| 39 | * from the author. |
| 40 | * 'Author' - The author's name |
| 41 | * 'AuthorURI' - The authors web site address. |
| 42 | * 'Version' - The plugin version number. |
| 43 | * 'PluginURI' - Plugin web site address. |
| 44 | * 'TextDomain' - Plugin's text domain for localization. |
| 45 | * 'DomainPath' - Plugin's relative directory path to .mo files. |
| 46 | * |
| 47 | * Some users have issues with opening large files and manipulating the contents |
| 48 | * for want is usually the first 1kiB or 2kiB. This function stops pulling in |
| 49 | * the plugin contents when it has all of the required plugin data. |
| 50 | * |
| 51 | * The first 8kiB of the file will be pulled in and if the plugin data is not |
| 52 | * within that first 8kiB, then the plugin author should correct their plugin |
| 53 | * and move the plugin data headers to the top. |
| 54 | * |
| 55 | * The plugin file is assumed to have permissions to allow for scripts to read |
| 56 | * the file. This is not checked however and the file is only opened for |
| 57 | * reading. |
