Send DM about all the channels to new users

[icyflame]

Please have a look at the message. You can get this message inside slack by sending send the joining message to me to @eva on Slack.

Thanks for doing this :)

[amrav]

Should be clarified to say that anyone can open pull requests, but only a few people can push the changes. I would prefer not to be the primary contact for pushing changes.

[icyflame]

Hi, sorry. I think I was in the middle of writing a sentence there. Yeah, I am removing this. Just letting people know that it is hosted on Heroku. PRs on GitHub are still the way to go!

[amrav]

See if you can get the channel names and short descriptions from slack automatically. This should be a map from channel name to long description, and then construct this message programmatically. That way Eva can respond to requests for long descriptions of individual channels as well.

[icyflame]

@amrav The channel descriptions are already in slack. This message is more of a primer of the channels that are active currently so that people can join immediately.

If you are thinking something like handwritten long messages for each channel which people can ask for from Eva, that's completely different. Tell me which one you had in mind.

[amrav]

This is the behaviour I'm thinking of:

1. When somebody joins Slack for the first time, they get a DM with a list of channels and their short descriptions. This is so that they don't have to browse through all the channels to know which ones exist and what they're for.
2. They can also do eva help <channel name>, which will give them a longer description of a channel.
3. The longer description should also automatically be sent whenever you join a channel for the first time.

This is designed to give a newcomer a decent overview, and also understand how to use the channels they join. Thoughts?

[icyflame]

Okay, I understand the idea. Question. Are these short descriptions the Slack channel's description themselves, or are they something else?

Clearly, we would need a long description map for each channel. This should not be too hard to write once we have a basic framework to work around with.

[icyflame]

@amrav Long descriptions implemented. For some reason, the sending of descriptions on people entering a channel is not working, despite being in the same block:

Will investigate some more. We need to fill out the JSON file with the long descriptions.

Changes have been implemented

[hargup]

@icyflame have you figured out what was wrong? This is very pretty cool feature to have.

[icyflame]

@hargup No, this is the version that is deployed right now, so I think we should merge this in, while I continue to work on the message that is sent when people enter channels. That's a different feature, so it's fine, I think.
