The following directory structure is required:
|
||
|
- python code: plugins/PLUGINNAME/PLUGINNAME.py (all lower case is recommended)
|
||
|
- language file: plugins/PLUGINNAME/language.hdf
|
||
|
- clearsilver templates: plugins/PLUGINNAME/*.cs
|
||
|
- icon (128x128px recommended): plugins/PLUGINNAME/plugin_icon.png
|
||
|
- css stylesheets (optional): plugins/PLUGINNAME/PLUGINNAME.css
|
||
|
|
||
|
|
||
|
Python code interface:
|
||
|
- create a class with the same name as the plugin - it must inherit CryptoBoxPlugin
|
||
|
- method "do_action":
|
||
|
- this function will get called whenever this plugins is involved in a request
|
||
|
- all arguments should be optional (e.g. for displaying a form without previous input values)
|
||
|
- if the processing failed for some reason (invalid input, ...), it should manually set
|
||
|
"Data.Warning" or "Data.Success") to a value of your choice (preferably
|
||
|
you may want to use messages of the namespace of your plugin
|
||
|
(e.g. "Plugins.PLUGINNAME.InvalidInput"))
|
||
|
- the return value should be the name of the template that should be displayed after processing
|
||
|
(a template file in the plugin directory takes precedence over global template files)
|
||
|
- the return value may also be a dictionary with the following elements:
|
||
|
* template: the name of the template file (mandatory)
|
||
|
* generator: a generator object ("yield") - its content will replace every
|
||
|
occurrence of "<!-- CONTENT_DUMMY -->" in the template (useful for pages that
|
||
|
are displayed step by step (as for formatting of filesystems))
|
||
|
- the return value may also be a dictionary with the following elements:
|
||
|
* plugin: the name of a plugin
|
||
|
* values: a dictionary of variables that should be defined for this plugin
|
||
|
- an empty (e.g. None) return value can be used to go to the default page ("disks"
|
||
|
or "volume_mount" (for volume plugins))
|
||
|
- access the plugin's state as self.prefs
|
||
|
- store user supplied values in the dictionary self.prefs with indices starting with "_" (e.g.: self.prefs["_automount_uuids"])
|
||
|
- system wide readonly plugin settings can be specified in the main cryptobox.conf -
|
||
|
these settings are available as self.defaults["..."]
|
||
|
- method "get_status":
|
||
|
- returns a string, that describes a state connected to this plugin (e.g. the current date and
|
||
|
time (for the "date" plugin))
|
||
|
- method "handle_event(event, event_info)":
|
||
|
- may be overridden to specify event handling (e.g. "bootup", "shutdown")
|
||
|
- see src/cryptobox/plugins/base.py for details
|
||
|
- the class variable "plugin_capabilities" must be an array of strings (supported: "system" and
|
||
|
"volume")
|
||
|
- method "is_useful(self, device)": defaults to "True" - overwrite it, if there could be circumstances, which could make the plugin useless - e.g. "automount" is not useful for encrypted containers
|
||
|
- method "get_warnings(self)": return a tuple of (Priority, WarningName) or None if
|
||
|
no problems exist
|
||
|
- "WarningName" should be something like "Plugins.PLUGINNAME.NoSSL"
|
||
|
- the class variable "plugin_visibility" may contain one or more of the following items:
|
||
|
menu/preferences/volume. This should fit to the 'plugin_capabilities' variable.
|
||
|
An empty list is interpreted as an invisible plugin.
|
||
|
- the class variable "request_auth" is boolean and defines, if admin authentication is necessary
|
||
|
for this plugin
|
||
|
- the class variable "rank" is an integer in the range of 0..100 - it determines the order
|
||
|
of plugins in listings (lower value -> higher priority)
|
||
|
- the class variable "root_action" is None or the module as sourced out of "root_actions.py"
|
||
|
in the directory of the plugin - this allows to access constant settings in this file
|
||
|
- volume plugins contain the attribute "device" (you may trust this value - a volume plugin will
|
||
|
never get called with an invalid device)
|
||
|
- the python module which contains the plugin's class should also contain a class called
|
||
|
'unittests' - it should inherit WebInterfaceTestClass.WebInterfaceTestClass
|
||
|
- method "download" is exposed as "downloads/PLUGINNAME"
|
||
|
|
||
|
|
||
|
Language file structure:
|
||
|
- the content of the language file will be added to the hdf dataset below "Lang.Plugins.PLUGINNAME"
|
||
|
(this avoids namespace conflicts)
|
||
|
- the following top level settings _must_ be defined:
|
||
|
Name (a short description)
|
||
|
Link (the visible text for links to this plugin)
|
||
|
- only system plugins: "Title" is necessary, too
|
||
|
- all warnings, hints and success messages as well as environment warnings should
|
||
|
be stored below WarningMessage/AdviceMessage/SuccessMessage/EnvironmentWarning
|
||
|
|
||
|
|
||
|
Clearsilver template:
|
||
|
- volume plugins do not have a title
|
||
|
- system plugins should contain '<?cs call:show_plugin_title() ?>' at the
|
||
|
top of the template
|
||
|
- the title should be followd by '<?cs call:handle_messages() ?>'
|
||
|
this will display important messages
|
||
|
- usually you should supply some helpful information afterwards (only displayed
|
||
|
if the user enabled inline-help before):
|
||
|
"<?cs call:show_help(Lang.Plugins.PLUGINNAME.Help.Text) ?>"
|
||
|
- links to the plugin (e.g. in form headers) could look like the following:
|
||
|
<?cs call:link("PLUGINNAME",'','','','') ?>
|
||
|
