| // discord command autocomplete | ||
| // | ||
| // @Switch for:<bot> to only process the event for a specified Discord bot. | ||
| // @Switch channel:<channel_id> to only process the event when it occurs in a specified Discord channel. | ||
| // @Switch group:<group_id> to only process the event for a specified Discord group. | ||
| // @Switch name:<command_name> to only process the event for a specified Discord application command. Spaces are replaced with underscores. | ||
| // @Switch option:<option_name> to only process the event for a specified autocompletable option. | ||
| // | ||
| // @Triggers when a Discord user queries a slash command option that can be autocompleted. | ||

| // @Plugin dDiscordBot | ||

| // @Context | ||
| // <context.bot> returns the relevant DiscordBotTag. | ||
| // <context.channel> returns the DiscordChannelTag. | ||
| // <context.group> returns the DiscordGroupTag. | ||
| // <context.interaction> returns the DiscordInteractionTag. | ||
| // <context.command> returns the DiscordCommandTag. | ||
| // <context.options> returns the supplied options as a MapTag. | ||
| // <context.focused_option> returns the name of the focused option. | ||
| // | ||
| // @Determine | ||
| // "CHOICES:" + ListTag to suggest values to the Discord client. Up to 25 suggestions are allowed to be sent. Each entry can be an ElementTag which controls both the value and display of the choice or a MapTag with "name" and "value" keys to control both separately. | ||

| // @Example | ||
| // # Suggests fruits that are only longer in length than the current input. | ||
| // on discord command autocomplete name:eat option:fruit: | ||
| // - define length <context.options.get[fruit].length> | ||
| // - define fruits <list[lime|apple|orange|blueberry|dragonfruit]> | ||
| // - determine choices:<[fruits].filter_tag[<[filter_value].length.is_more_than[<[length]>]>]> | ||
| // | ||
| // @Example | ||
| // # Suggests the 25 best-matching selections from some dataset against the current input. | ||
| // on discord command autocomplete: | ||
| // - define value <context.options.get[<context.focused_option>]> | ||
