What kind of things could be discussed in this stream?

Mario Carneiro (May 11 2021 at 17:11):

Anything relating to mathlib porting, the mathlib4 repo, the interaction of lean 4 features and mathlib

Daniel Fabian (May 11 2021 at 17:17):

are you aware of the delaborator efforts by @Daniel Selsam , btw?

Mario Carneiro (May 11 2021 at 17:19):

The mathlib4 repo is introduced in this post. As mentioned there, the intent is for this to be a temporary from-scratch lean 4 repo, which will later be replaced by the results of porting. Tactics in particular are not slated for porting so they will have to be written from scratch anyway

Mario Carneiro (May 11 2021 at 17:20):

I will be manually porting a few more files but I expect not to get much further than data.nat.basic and data.list.basic, which covers most of the essentials for CS applications

(To everyone who was pinged by the stream announcement: Sorry about that! Feel free to ignore.)

Sounds fun!

If manual imports are the norm for now, is there some way we can organize who is doing what so that we don't reduplicate effort. For example, make a list of files (and/or sections of files) that would be noteworthy to port and have people comment what things they would like to take the reigns on.

It might be a nice way to get the community more into working with Lean 4 if there were some concrete goals to complete (that also have the reward of benefiting the community). I know it would interest me.
