Ragwort

Unstable experiments with pycord. An adaptation of tansy.

Slash Commands

ragwort provides a unique way to define options for slash commands.

Instead of needing a decorator per option or to define the option in one huge list (or using awkward annotations), ragwort allows you to define each option in the function itself. By using a special metadata function, you can specify what each argument/parameter in a function should be like as an option, with ragwort smartly handling the rest for you.

import discord
import ragwort

bot = discord.Bot(...)

@ragwort.slash_command(description="Nice test command, huh?")
async def test(
    ctx: discord.ApplicationContext,
    the_user: discord.Member = ragwort.Option(name="user", description="The user to ping."),
):
    await ctx.respond(the_user.mention)

bot.add_application_command(test)  # only needed if the command is not in a cog

[!TIP] You can also use from ragwort import X for individual imports if you prefer.

ragwort frequently also aliases classes and functions to make overlap between ragwort and discord easier to avoid; for example, instead of ragwort.slash_command, you could use ragwort_slash_command.

Subcommands

ragwort also supports defining subcommands in a similar way.

# see imports from last example

math = ragwort.SlashCommandGroup("math", "Math related commands")
advanced = math.create_subgroup("advanced", "Advanced math commands")

@advanced.command()
async def square_root(
    ctx: discord.ApplicationContext,
    x: int = ragwort.Option(description="The number to find the square root of.")
):
    await ctx.respond(x ** 0.5)

Bridge Commands

ragwort also provides support for bridge commands:

import discord
from discord.ext import bridge
import ragwort

bot = bridge.Bot(...)

@ragwort.bridge_command(description="Nice test command, huh?")
async def test(
    ctx: bridge.BridgeContext,
    the_user: discord.Member = ragwort.BridgeOption(name="user", description="The user to ping."),
):
    await ctx.respond(the_user.mention)

bot.add_bridge_command(test)  # only needed if the command is not in a cog

Autocomplete

ragwort also adds a new way of handling autocomplete functions for slash commands and bridge commands:

@ragwort.slash_command(name="animal")
async def animal_command(
    ctx: discord.ApplicationContext,
    animal_type: str = ragwort.Option(
        "The type of animal.", choices=["Marine", "Land"]
    ),
    animal: str = ragwort.Option("The animal you want to pick."),
):
    await ctx.respond(
        f"You picked an animal type of `{animal_type}` that led you to pick `{animal}`!"
    )


@animal_command.autocomplete("animal")
async def animal_autocomplete(ctx: discord.AutocompleteContext):
    animal_type = ctx.options["animal_type"]
    if animal_type == "Marine":
        options = ["Whale", "Shark", "Fish", "Octopus", "Turtle"]
    else:
        options = ["Snake", "Wolf", "Lizard", "Lion", "Bird"]

    return [o for o in options if o.lower().startswith(ctx.value.lower())]

Auto Defer

ragwort provides a way of making all slash commands automatically defer their responses, and the ability to change how said auto defer works at the bot, cog, and command levels.

To use auto defer, you can call the setup_auto_defer function with your bot instance:

import discord
import ragwort

bot = discord.Bot(...)
ragwort.setup_auto_defer(bot)

Bot Wide Auto Defer

By default, setup_auto_defer enables auto defer for all commands. However, you can change ragwort.setup_auto_defer to whatever you desire:

# only defers extensions and commands marked
# to be autodeferred - see the next sections
ragwort.setup_auto_defer(bot, default=False)

# or
ragwort.setup_auto_defer(
    bot,
    default=ragwort.AutoDefer(
        enabled=True,
        ephemeral=False,
        time_until_defer=0.0
    )  # allows more custom behavior
)

Cog Wide Auto Defer

You can also set up auto defer at the cog level by using the cog_auto_defer decorator. This will apply the auto defer settings to all commands within that cog:

@ragwort.cog_auto_defer(enabled=True, ephemeral=False, time_until_defer=0.0)
class MyCog(discord.Cog):
    @ragwort.slash_command()
    async def my_command(self, ctx: discord.ApplicationContext):
        await ctx.respond("Hello, World!")

Command Level Auto Defer

Finally, you can set up auto defer at the command level by using the auto_defer decorator. This will apply the auto defer settings to that specific command:

@ragwort.slash_command()  # works for normal slash commands too
@ragwort.auto_defer(enabled=True, ephemeral=False, time_until_defer=0.0)
async def my_command(self, ctx: discord.ApplicationContext):
    await ctx.respond("Hello, World!")

Other Notes

• Auto defer is applied in the following order: command level, then cog level, then bot level. This means that if a command has auto defer disabled (with enabled=False), but the cog or bot has it enabled, the command will not be deferred. This is useful for commands that send modals.
• Auto defer partially works with bridge commands; the slash variant of the command will be deferred, but the prefixed variant will not be.
