Typing `:` starts a new symbol

[nrk-simen-munthe-endsjo]

: is used for package designators in Common Lisp, and often in Scheme too. Typing a:b inserts a space a :b, requiring a manual deletion of the added space. It seems more correct if : was just a part of the symbol without triggering the space.

I just found lispy-colon-p which is set to t by default. Not sure what the rationale is or if it's a bug in lispy-colon-no-space-regex.

@nrk-simen-munthe-endsjo you know, this was bugging me for the longest time and I never bothered to look into it, as I figured maybe it was a "me" problem.

I agree with you; I have no idea why this is the default! I am guessing maybe in some other Lisp (Clojure?) this is helpful, as I recall abo-abo being a Clojure dev.

I am wondering if we should change the default. What do you think @nrk-simen-munthe-endsjo ?

Generally it's in poor taste to change a default like this, but this is a really puzzling default.

It probably makes sense for Clojure. It doesn't use : for package designators, and it use : for keywords. The keywords can also act as functions, and it's a lisp-1. I haven't coded any Clojure, but it's probably what people want.

For Common Lisp, I think it's a bad default. : is used for keywords too, but as it's used for packages too, it often gets in the way. So while it's a breaking change, I would expect it's for the better.

I guess Scheme doesn't want this feature either as : is just a regular symbol which can be used, and keywords are prefixed with #:. And : is often used as a package prefix there too. Also a breaking change, but a good one in my book.

So maybe lispy-colon-p should be dependant on the major mode? Keep the default of t for Clojure, but nil for Common Lisp and Scheme?

@nrk-simen-munthe-endsjo I think we should just keep adding modes to lispy-colon-no-space-regex as I did here:

Notably in my scenario, SLY was missing but SLIME was present.

Which other modes do you think we should add to this variable
