Obtain channel ID about slack HOT 4 CLOSED

@leolara If you've already established an RTM connection, I would suggest iterating over the Channels slice of the Info struct to find what you're looking for: https://godoc.org/github.com/nlopes/slack#Info

func FindChannelByName(rtm *slack.RTM, name string) *slack.Channel {
    for _, ch := range rtm.GetInfo().Channels {
        if ch.Name == name {
            return &ch
        }
    }
    return nil
}

The only gotcha there is that if a channel is renamed, the Info struct won't get updated. If you need to support that use case, you could keep your own copy of the Channels slice and update it manually every time you receive a ChannelRenameEvent over the RTM connection.

Hope this helps!

@leocassarani yes, that is what I thought!! But, how do I get the channel ID from the Channel struct?

from slack.

@leolara Channel embeds groupConversation, which embeds conversation, so you're looking for channel.ID: https://github.com/nlopes/slack/blob/4a9ff5f6ed8bb0df51620f49ee90fc0858a2913e/conversation.go#L5

However, I think your confusion is understandable here. Because those embedded structs are private, they don't show up in GoDoc. I myself have struggled with that at one point or another.

@nlopes any thoughts on making those private structs public, or finding some other way to make the fields show up in GoDoc?

@leocassarani

I do not think it is possible to do that, which is a bad thing for godoc.

Why groupConversation and conversation should be private? Perhaps the solution is to make them public.
