Slack API thoughts

I’m working on a Slack integration that marries the Riot games API to the Slack API, for a group of League of Legends gamers I play with. I’ve been doing simple message posting from a cron job for 6 months now and it works great. Now doing fancier stuff.

I’m not a fan of the message formatting options. There’s the basic markup which they call “markdown” even though it’s not markdown. Then you can add attachments which has a bit of a tabular layout to them but it’s not very flexible. I can’t make it look like what I want, so I’m reduced to doing fixed-width formatting of plain text. Ugly. I wish they’d let me do free form HTML but I guess they’re aiming for display consistency so don’t want that.

I am impressed with how easy it is to add basic slash commands though. You can just create a “Configuration” that causes /foo to fire off a POST to the URL of your choice. Done! There’s fancier stuff for installable commands, too.

Last comment; the that looks official is not awesome. There’s no proper release schedule so what’s on PyPI is out of date. And it seems to rely on an odd websockets implementation. I may want to look into alternative Python wrappers if I do anything too complicated. I’ve only been using the REST Web API so far, not any streams.
