# Yaboli
Yaboli (**Y**et **A**nother **Bo**t **Li**brary) is a Python library for
creating bots for [euphoria.io](https://euphoria.io).
- [Documentation](docs/index.md)
- [Changelog](CHANGELOG.md)
## Installation
Ensure that you have at least Python 3.7 installed.
To install yaboli or update your installation to the latest version, run:
```
$ pip install git+https://github.com/Garmelon/yaboli@v1.2.0
```
The use of [venv](https://docs.python.org/3/library/venv.html) is recommended.
## Example echo bot
A simple echo bot that conforms to the
[botrulez](https://github.com/jedevc/botrulez) can be written like so:
```python
class EchoBot(yaboli.Bot):
HELP_GENERAL = "/me echoes back what you said"
HELP_SPECIFIC = [
"This bot only has one command:",
"!echo <text> reply with exactly <text>",
]
def __init__(self, config_file):
super().__init__(config_file)
self.register_botrulez(kill=True)
self.register_general("echo", self.cmd_echo)
async def cmd_echo(self, room, message, args):
await message.reply(args.raw)
```
The bot's nick, cookie file and default rooms are specified in a config file,
like so:
```ini
[general]
nick = EchoBot
cookie_file = bot.cookie
[rooms]
test
```
The help command from the botrulez uses the `HELP_GENERAL` and `HELP_SPECIFIC`
fields.
In the `__init__` function, the bot's commands are registered. The required
botrulez commands (!ping, !help, !uptime) are enabled by default. Other
commands like !kill need to be enabled explicitly.
In the `cmd_echo` function, the echo command is implemented. In this case, the
bot replies to the message containing the command with the raw argument string,
i. e. the text between the end of the "!echo" and the end of the whole message.
The full version of this echobot can be found [in the
examples](examples/echo/).
## TODOs
- [ ] document yaboli (markdown files in a "docs" folder?)
- [ ] document new classes (docstrings, maybe comments)
- [ ] write examples
- [ ] make yaboli package play nice with mypy
- [x] implement !uptime for proper botrulez conformity
- [x] implement !kill
- [x] untruncate LiveMessage-s
- [x] config file support for bots, used by default
- [x] make it easier to enable log messages
- [x] make it easier to run bots
- [x] package in a distutils-compatible way (users should be able to install
yaboli using `pip install git+https://github.com/Garmelon/yaboli`)
- [x] implement !restart
- [x] write project readme
- [x] cookie support
- [x] fancy argument parsing

# Index for yaboli docs

- Classes
- [Bot](bot.md)
## Getting started
First, read the [overview](#library-structure-overview) below.
To set up your project, follow the [setup guide](bot_setup.md).
To get a feel for how bots are structured, have a look at the example bots or
read through the docstrings in the `Bot` class.
## Library structure overview
### Message, Session
A `Message` represents a single message. It contains all the fields [specified
in the API](http://api.euphoria.io/#message), in addition to a few utility
functions.
Similar to a `Message`, a `Session` represents a [session
view](http://api.euphoria.io/#sessionview) and also contains almost all the
fields specified in the API, in addition to a few utility functions.
`Message`s and `Session`s also both contain the name of the room they
originated from.
### Room
A `Room` represents a single connection to a room on euphoria. It tries to keep
connected and reconnects if it loses connection. When connecting and
reconnecting, it automatically authenticates and sets a nick.
In addition, a `Room` also keeps track of its own session and the sessions of
all other people and bots connected to the room. It doesn't remember any
messages though, since no "correct" solution to do that exists and the method
depends on the design of the bot using the `Room` (keeping the last few
messages in memory, storing messages in a database etc.).
### LiveMessage, LiveSession
`LiveMessage`s and `LiveSession`s function the same as `Message`s and
`Session`s, with the difference that they contain the `Room` object they
originated from, instead of just a room name. This allows them to also include
a few convenience functions, like `Message.reply`.
Usually, `Room`s and `Client`s (and thus `Bot`s) will pass `LiveMessage`s and
`LiveSession`s instead of their `Message` and `Session` counterparts.
### Client
A `Client` may be connected to a few rooms on euphoria and thus manages a few
`Room` objects. It has functions for joining and leaving rooms on euphoria, and
it can also be connected to the same room multiple times (resulting in multiple
`Room` objects).
The `Client` has a few `on_<event>` functions (e. g. `on_message`, `on_join`)
that are triggered by events in any of the `Room` objects it manages. This
allows a `Client` to react to various things happening in its `Room`s.
### Bot
A `Bot` is a client that:
- is configured using a config file
- reacts to commands using a command system
- implements most commands specified in the
[botrulez](https://github.com/jedevc/botrulez)
The config file includes the bot's default nick, initial rooms and bot-specific
configuration. Upon starting a `Bot`, it joins the rooms specified in the
config, setting its nick to the default nick.
The command system can react to general and specific commands as specified in
the botrulez, and can parse command arguments with or without bash-style string
escaping, and with or without unix-like syntax (flags and optional arguments).
### Module, ModuleBot
A `Module` is a `Bot` that can also be used as a module in a `ModuleBot`. This
is like combining multiple bots into a single bot.
The most notable differences are the new `DESCRIPTION` and `standalone` fields.
The `DESCRIPTION` field contains a short description of the module, whereas the
`standalone` field answers the question whether the `Module` is being run as
standalone bot or part of a `ModuleBot`.

# Different ways of parsing commands:

# - raw string

class FancyArgs(NamedTuple):
"""
The fancy argument parser supports arguments of the following formats:
FLAGS:
These are one or more characters preceded by a single dash. Examples:
-a, -fghf, -vv
The fancy argument parser counts how often each character (also called
flag) appears. Each flag that appears once or more gets an entry in the
"flags" dict of the form: flags[flag] = amount
Exception: A single dash ("-") is interpreted as a positional argument.
OPTIONAL:
These are arguments of the form --<name> or --<name>=<value>, where <name>
is the name of the optional argument and <value> is its (optional) value.
Due to this syntax, the <name> may not include any "=" signs.
The optional arguments are collected in a dict of the form:
optional[name] = value or None
If the optional argument included a "=" after the name, but no further
characters, its value is the empty string. If it didn't include a "=" after
the name, its value is None.
If more than one optional argument appears with the same name, the last
argument's value is kept and all previous values discarded.
POSITIONAL:
Positional arguments are all arguments that don't start with "-" or "--".
They are compiled in a list and ordered in the same order they appeared in
after the command.
RAW:
At any time, a single "--" argument may be inserted. This separates the
positional and optional arguments and the flags from the raw arguments. All
arguments after the "--" are interpreted as raw arguments, even flags,
optional arguments and further "--"s.
For example, consider the following arguments:
ab -cd -c --ef=g --h i -- j --klm -nop -- qr
positional: ["ab", "i"]
optional: {"ef": "g", "h": None}
flags: {"c": 2, "d": 1}
