# **DocLib**
A chatbot library for euphoria.io.
# Usage
## Installation
To install, use `pip` or `pip3`:
```bash
pip3 install doclib
```
**WINDOWS USERS: YOU MUST [INSTALL WSL](https://docs.microsoft.com/en-us/windows/wsl/install-win10 "A tutorial for doing so") AND RUN THIS ON IT IN ORDER FOR IT TO WORK**
When beginning a new bot, import the `Bot` class:
```python
from doclib import Bot
```
## Basic Bots
A basic bot will be a `Bot` object, constructed with a `nick`(the bot's name, shown in the room), a `room`(where the bot is sent by default, defaults to bots or test in debug mode), and an `owner`(your euphoria username.):
```python
sampleBot = Bot(nick = 'bugBot', room = 'test', owner = 'sample user')
```
### Constructor Options
| option | default | usage |
| -------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ | :------------------------------------------------------------------------------------------------------------------------------------------- |
| `nick` | none, this is required | The nick the bot will enter the room with. |
| `room` | `"bots"` | The default room for the bot to be sent to. |
| `owner` | `"nobody"` | The owner/creator of the bot (you). |
| `password` | blank string | room password (used for private rooms) |
| `help` | `"[nick] is a bot made with Doctor Number Four's Python 3 bot library, DocLib (link: https://github.com/milovincent/DocLib) by @[owner]. `<br>`It follows botrulez and does not have a custom !help message yet."` | your custom !help command response. can also be set by adding a `"^!help @[nick w/o spaces]$"` command to your regexes |
| `ping` | `"Pong!"` | your custom !ping response. |
| `important` | `False` | if `True`, the bot will only be killable by a roomhost or the owner. **NOT RECOMMENDED FOR SIMPLE BOTS OR BOTS PRONE TO SPAM**. |
| `killed` | `"/me has died"` | your custom message sent when bot is !killed. |
| `API_timeout` | `10` | ADVANCED: number of API responses to check for command responses. You should not need to change this unless the room is particularly active. |
| `advanced` | `False` | ADVANCED: if `True`, declares the bot as advanced, enabling the user to directly handle any API response (while still obeying botrulez) |
| `function` | `None` | ADVANCED: specifies the universal advanced start handler function. |
| `customArgs` | `False` | ADVANCED: Removes the set of default command-line arguments for bots. |
| `sendable` | `False` | If `True`, enables the bot to be sent to other rooms with the !send @bot &room command. |
| `human` | `False` | If `True`, the bot shows up in the People list. If used improperly, this is against Euphoria's ToS. |
| `killChildren` | `False` | If `True`, when killed, the bot will kill any copies it has made as well. |
Once constructed, the user should assign a regex dictionary for non-advanced use cases:
```python
sampleBot.set_regexes({r'^!command$': function,
r'(?i)word': 'response',
r'^!bunchamessages$':
{
"message": "nick to use",
"second message": "different nick"
},
r'^!afewmessages$':
[
"first message",
"second message"
]
}
)
```
#### Regex Formatting
DocLib uses the default python `re` library for regex formatting.
## Custom Function Responses
Responses with a function value run the function with a `Bot` object (`chatbot`), an `AttrDict` (`msg`), and the regex `match` object (`matches`). Functions can utilise any of the numerous `Bot` methods and all return the API's reply as an `AttrDict`:
| Method | Parameters | Effect |
| -------------- | -------------------------------------------------------------------- | :---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| `send_msg` | `parent` (`AttrDict` or string), `msgString` (string) | Sends `msgString` as a reply to `parent`, where `parent` can either be a string containing the message id returned by the API or an `AttrDict` with the structure of a `send-reply` generated by the API (recommended: use the `msg` parameter given to your custom function) |
| `set_nick` | `nick` (string) | Sets the bot's name to `nick` |
| `get_userlist` | none | returns an array of user `AttrDict`s currently in the room, including bots, accounts, and agents. |
| `move_to` | `roomName` (string), `password` (string, default is an empty string) | Moves the bot to a different room, specified by `roomName`, and, if necessary, attempts to log into it using `password`. |
| `restart` | none | Restarts the bot. |
| `kill` | none | Kills the bot. |
| `copy_to` | `roomName` (string), `password` (string, default is an empty string) | Creates a new `Bot` object set to appear in &`roomName` and returns it. The user can then start it in a separate thread with the `start_in_new_thread` function. |
| `initiate_pm` | `id` (string), `bot` (`Bot`, default None) | Starts a PM with the user `id`, placing `bot` in said PM room if specified, else a copy of the bot receiving the command. |
| `login` | `email` (string), `password` (string) | Logs bot in as a user. Takes effect on reconnect, and the bot will show up in the People list. |
To log errors and info, use `Bot.log` with a `message` string and the optional `error` boolean. (note: NOT a `Bot` subfunction) To choose between a set of responses to a command randomly (including dictionaries, strings, and even functions), use `Bot.randomize_between(*responses)`.
The regex string for any command may be replaced with a function that takes the relevant `AttrDict` `msg` object and returns a boolean (`True` to respond, `False` to continue).
### Example:
Regex:
```python
sampleBot.set_regexes({'^!alive$': alive})
```
Function (defined **above bot start**)
```python
def alive(chatbot, msg, matches):
chatbot.send_msg(parent = msg, msgString = '/me IS ALIVE!')
chatbot.set_nick('Thunder')
chatbot.send_msg(parent = msg, msgString = '/me crashes')
chatbot.set_nick('sampleBot')
```
## Custom Handlers
To set custom function handlers for any API response (when not `advanced`, this does not include `ping-event`s, `send-event`s, `error`s, or `bounce-event`s), use `set_handler`:
```python
sampleBot.set_handler(eventString = "join-event", on_join)
```
or
```python
sampleBot.set_handlers({"joinEvent": on_join})
```
All handler functions, including the universal function parameter for advanced start, are passed the API response (`msg`) as an `AttrDict` every time the corresponding event is received. Custom handlers take precedence over advanced start's universal handler.
# Startup
Once the bot is set up and populated with commands, the user can connect and start it:
```python
sampleBot.connect()
sampleBot.start()
```
To start a bot in a new thread (useful for copies), use the `start_in_new_thread` function instead:
```python
copy.connect()
copy.start_in_new_thread()
```
## Advanced Usage
Using an `advanced` value of `True` (whether in the bot's declaration or its start function) enables the user to set a universal handler for all API events, in addition to any custom handlers:
```python
sampleBot.start(advanced = True, function = handler_function)
```
If unspecified, advanced start uses a filler function that does nothing, enabling the user to use entirely custom handlers for every API response.
# Command Line Options
When running any bot in the command line, the user has access to a few default options:
| option | usage |
| ------------------------------------ | :------------------------------------------------------------------------ |
| `-t`, `--test`, `--debug` | Used to debug dev builds. Sends bot to &test instead of its default room. |
| `--room ROOM`, `-r ROOM` | Sends bot to &ROOM instead of its default room. |
| `--password PASSWORD`, `-p PASSWORD` | Password to use should the room be locked. |
To add new arguments, use the bot's `add_command_line_arg` function as you would the default Python `argparse.add_argument` function. It returns the value of the added argument if provided a `name` parameter. To remove the default arguments, set `customArgs` in the `Bot` constructor to `True`.
