* Parse the plugin contents to retrieve plugin's metadata.
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.
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
32
* Network: Optional. Specify "Network: true" to require that a plugin is activated
33
* across all sites in an installation. This will prevent a plugin from being
34
* activated on a single site when Multisite is enabled.
35
* * / # Remove the space to close comment
38
* Plugin data returned array contains the following:
39
* 'Name' - Name of the plugin, must be unique.
40
* 'Title' - Title of the plugin and the link to the plugin's web site.
41
* 'Description' - Description of what the plugin does and/or notes
43
* 'Author' - The author's name
44
* 'AuthorURI' - The authors web site address.
45
* 'Version' - The plugin version number.
46
* 'PluginURI' - Plugin web site address.
47
* 'TextDomain' - Plugin's text domain for localization.
48
* 'DomainPath' - Plugin's relative directory path to .mo files.
49
* 'Network' - Boolean. Whether the plugin can only be activated network wide.
51
* Some users have issues with opening large files and manipulating the contents
52
* for want is usually the first 1kiB or 2kiB. This function stops pulling in
53
* the plugin contents when it has all of the required plugin data.
55
* The first 8kiB of the file will be pulled in and if the plugin data is not
56
* within that first 8kiB, then the plugin author should correct their plugin
57
* and move the plugin data headers to the top.
59
* The plugin file is assumed to have permissions to allow for scripts to read
60
* the file. This is not checked however and the file is only opened for
63
* @link http://trac.wordpress.org/ticket/5651 Previous Optimizations.
64

67
