## Installation
Crescent is supported in python3.9+.
```
pip install hikari-crescent
```

## Bots using Crescent

- [mCodingBot](https://github.com/mcb-dev/mCodingBot) - The bot for the mCoding Discord server.
- [Starboard 3](https://github.com/circuitsacul/starboard-3) - A starbord bot by [@CircuitSacul](https://github.com/CircuitSacul)
in over 17k servers.


## Usage
Crescent uses [class commands](https://github.com/hikari-crescent/hikari-crescent/blob/main/examples/basic/basic.py)
to simplify creating commands. Class commands allow you to create a command similar to how you declare a
dataclass. The option function takes a type followed by the description, then optional information.

```python
import crescent
import hikari

bot = hikari.GatewayBot("YOUR_TOKEN")
client = crescent.Client(bot)

# Include the command in your client - don't forget this
@client.include
# Create a slash command
@crescent.command(name="say")
class Say:
    word = crescent.option(str, "The word to say")

    async def callback(self, ctx: crescent.Context) -> None:
        await ctx.respond(self.word)

bot.run()
```

Simple commands can use functions instead of classes. It is recommended to use a function when your
command does not have any options.

```python
@client.include
@crescent.command
async def ping(ctx: crescent.Context):
    await ctx.respond("Pong!")
```

### Typing to Option Types Lookup Table 
| Type | Option Type |
|---|---|
| `str` | Text |
| `int` | Integer |
| `bool` | Boolean |
| `float` | Number |
| `hikari.User` | User |
| `hikari.Role` | Role |
| `crescent.Mentionable` | Role or User |
| Any Hikari channel type. | Channel. The options will be the channel type and its subclasses. |
| `List[Channel Types]` | Channel. ^ |
| `hikari.Attachment` | Attachment |


### Autocomplete
Autocomplete is supported by using a callback function. This function returns a list of tuples where the first
value is the option name and the second value is the option value. `str`, `int`, and `float` value types
can be used.

```python
async def autocomplete(
    ctx: crescent.AutocompleteContext, option: hikari.AutocompleteInteractionOption
) -> list[tuple[str, str]]:
    return [("Option 1", "Option value 1"), ("Option 2", "Option value 2")]

@client.include
@crescent.command(name="class-command")
class ClassCommand:
    option = crescent.option(str, autocomplete=autocomplete)

    async def callback(self) -> None:
        await ctx.respond(self.option)
```

### Error Handling
Errors that are raised by a command can be handled by `crescent.catch_command`.

```python
class MyError(Exception):
    ...

@client.include
@crescent.catch_command(MyError)
async def on_err(exc: MyError, ctx: crescent.Context) -> None:
    await ctx.respond("An error occurred while running the command.")

@client.include
@crescent.command
async def my_command(ctx: crescent.Context):
    raise MyError()
```

There is also a `crescent.catch_event` and `crescent.catch_autocomplete` function for
events and autocomplete respectively.

### Events
```python
import hikari

@client.include
@crescent.event
async def on_message_create(event: hikari.MessageCreateEvent):
    if event.message.author.is_bot:
        return
    await event.message.respond("Hello!")
```
Using crescent's event decorator lets you use
crescent's [event error handling system](https://github.com/hikari-crescent/hikari-crescent/blob/main/examples/error_handling/basic.py#L27).

# Extensions
Crescent has 3 builtin extensions.

- [crescent-ext-cooldowns](https://github.com/hikari-crescent/hikari-crescent/tree/main/examples/ext/cooldowns) - Allows you to add sliding window rate limits to your commands.
- [crescent-ext-locales](https://github.com/hikari-crescent/hikari-crescent/tree/main/examples/ext/locales) - Contains classes that cover common use cases for localization.
- [crescent-ext-tasks](https://github.com/hikari-crescent/hikari-crescent/tree/main/examples/ext/tasks) - Schedules background tasks using loops or cronjobs.

These extensions can be installed with pip.

- [crescent-ext-docstrings](https://github.com/hikari-crescent/crescent-ext-docstrings) - Lets you use docstrings to write descriptions for commands and options.
- [crescent-ext-kebabify](https://github.com/hikari-crescent/crescent-ext-kebabify) - Turns your command names into kebabs!
