v0.19.0

Warning
This update contains breaking changes!

In order to make the code of ken more type-safe, I am now using safepool instead of sync.Pool which uses generic type parameters for ensuring type safety. Therefore, the minimum required module version has been bumped to go1.18. You might need to upgrade your project accordingly to be able to use ken.

Autocomplete Support [#18]

Command option autocomplete
support has now been added to ken.

Simply enable autocomplete on your command option by setting the Autocomplete property to true.

Example:

func (c *TestCommand) Options() []*discordgo.ApplicationCommandOption {
	return []*discordgo.ApplicationCommandOption{
		{
			Type:         discordgo.ApplicationCommandOptionString,
			Name:         "language",
			Required:     true,
			Description:  "Choose a programming language.",
			Autocomplete: true,
		},
	}
}

Now, you simply need to implement the AutocompleteCommand
on your command.

Example:

func (c *TestCommand) Autocomplete(ctx *ken.AutocompleteContext) ([]*discordgo.ApplicationCommandOptionChoice, error) {
	input, ok := ctx.GetInput("language")

	if !ok {
		return nil, nil
	}

	choises := make([]*discordgo.ApplicationCommandOptionChoice, 0, len(programmingLanguages))
	input = strings.ToLower(input)

	for _, lang := range programmingLanguages {
		if strings.HasPrefix(lang[1], input) {
			choises = append(choises, &discordgo.ApplicationCommandOptionChoice{
				Name:  lang[0],
				Value: lang[0],
			})
		}
	}

	return choises, nil
}

The full example can be found in examples/autocomplete.

To properly handle errors occuring during autocomplete handling, a new command handler hook OnEventError has been added to the Options. It will be called every time a non-command related user event error occurs.

RespondMessage

A new respond method has been added to the ContentResponder called RespondMessage. It simply takes a message as parameter and responds with a simple message content containing the passed message.
