# PyLink Services Bot API
|
||
|
|
|
||
|
|
Starting with PyLink 0.9.x, a services bot API was introduced to make writing custom services slightly easier. PyLink's Services API automatically connects service bots, and handles rejoin on kick/kill all by itself, meaning less code is needed per plugin to have functional service bots.
|
||
|
|
|
||
|
|
## Creating new services
|
||
|
|
|
||
|
|
Services can be created (registered) using code similar to the following in a plugin:
|
||
|
|
|
||
|
|
```python
|
||
|
|
|
||
|
|
from pylinkirc import utils, world
|
||
|
|
|
||
|
|
# Description is optional (though recommended), and usually around a sentence or two.
|
||
|
|
desc = "Optional description of servicenick, in sentence form."
|
||
|
|
|
||
|
|
# First argument is the internal service name.
|
||
|
|
# utils.registerService() returns a utils.ServiceBot instance, which can also be found
|
||
|
|
# by calling world["myservice"].
|
||
|
|
myservice = utils.registerService("myservice", desc=desc)
|
||
|
|
```
|
||
|
|
|
||
|
|
`utils.registerService()` passes its arguments directly to the `utils.ServiceBot` class constructor, which in turn supports the following options:
|
||
|
|
|
||
|
|
- **`name`** - defines the service name (mandatory)
|
||
|
|
- `default_help` - Determines whether the default HELP command should be used for the service. Defaults to True.
|
||
|
|
- `default_list` - Determines whether the default LIST command should be used for the service. Defaults to True.
|
||
|
|
- `nick`, `ident` - Sets the default nick and ident for the service bot. If not given, these simply default to the service name.
|
||
|
|
- `manipulatable` - Determines whether the bot is marked manipulatable. Only manipulatable clients can be force joined, etc. using PyLink commands. Defaults to False.
|
||
|
|
- `extra_channels` - Defines a dict mapping network names to a set of channels that the bot should autojoin on that network.
|
||
|
|
- `desc` - Sets the command description of the service. This is shown in the default HELP command if enabled.
|
||
|
|
|
||
|
|
### Getting the UID of a bot
|
||
|
|
|
||
|
|
Should you want to get the UID of a service bot on a specific server, use `myservice.uids.get('irc.name')`
|
||
|
|
|
||
|
|
### Setting channels to join
|
||
|
|
|
||
|
|
All services bots wil automatically join the autojoin channels configured for a specific network, if any.
|
||
|
|
|
||
|
|
However, plugins can modify the autojoin entries of a specific bot by adding items to the `myservice.extra_channels` channel set. After sending `irc.proto.join(...)` using the service bot's UID as a source, the bot should permanently remain on that channel throughout KILLs or disconnects.
|
||
|
|
|
||
|
|
## Removing services on unload
|
||
|
|
|
||
|
|
All plugins using the services API **MUST** have a `die()` function that unregisters all services that they've created. A simple example would be in the `games` plugin:
|
||
|
|
|
||
|
|
```python
|
||
|
|
def die(irc):
|
||
|
|
utils.unregisterService('games')
|
||
|
|
```
|
||
|
|
|
||
|
|
## Service bots and commands
|
||
|
|
|
||
|
|
Commands for service bots and commands for the main PyLink bot have two main differences.
|
||
|
|
|
||
|
|
1) Commands for service bots are bound using `myservice.add_cmd(cmdfunc, 'cmdname')` instead of `utils.add_cmd(...)`
|
||
|
|
|
||
|
|
2) Replies for service bot commands are sent using `myservice.reply(irc, text)` instead of `irc.reply(...)`
|
||
|
|
|
||
|
|
### Featured commands
|
||
|
|
|
||
|
|
Commands for service bots can also be marked as *featured*, which shows it with its command arguments in the default `LIST` command. To mark a command as featured, use `myservice.add_cmd(cmdfunc, 'cmdname', featured=True)`.
