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
|
|
- function "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)
|
|
- the argument "store" should be used to process a form submission (just a recommendation)
|
|
- 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. "Data.Plugins.PLUGINNAME.WarningMessage.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))
|
|
- function "get_status":
|
|
- returns a string, that describes a state connected to this plugin (e.g. the current date and
|
|
time (for the "date" plugin))
|
|
- function "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")
|
|
- 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)
|
|
- 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
|
|
|
|
|
|
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)
|
|
- all warnings, hints and success messages should be stored below WarningMessage.???
|
|
(resp. AdviceMessage or SuccessMessage)
|
|
|
|
|
|
Clearsilver template:
|
|
- heading:
|
|
- non-volume plugins: "<h1>"
|
|
- volume plugins: "<?cs var:plugin_heading ?>" (very important - otherwise
|
|
embedding of plugins breaks (see 'volume_properties'))
|
|
- the title should be followd by '<?cs call:handle_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",'','','','') ?>
|
|
|
