"""
Replace some patterns in a message before sending it.
Usage
-----
Insert a pattern in the form
.. code-block:: none
%pattern%
in your message, and it will be replaced by the corresponding text.
The list of provided patterns is:
- **time**: Insert the current time
- **date**: Insert the current date
- **datetime**: Insert the current date and time
- **random_nick**: Insert a random nick from the current MUC
- **dice**: Insert a random number between 1 and 6
Add your own pattern
--------------------
You can easily edit this plugin to add your own patterns. For example if
don’t want to search for an insult everytime you’re angry, you can create a
curse pattern this way:
- In the init(self) method of the Plugin class, add something like
.. code-block:: python
self.patterns['curse'] = replace_curse
- then define a function (not a method of the Plugin class) at the bottom
of the file. For example:
.. code-block:: python
def replace_curse(message, tab):
return random.choice(['dumb shit', 'idiot', 'moron'])
and you can now use something like
.. code-block:: none
Shut up, %curse%!
in your everyday-conversations.
For more convenience, you can read your nice words from a file, do whatever
you want in that function, as long as it returns a string.
