is there a way to have cursive sort all the map keys in an edn file alphabetically?

maps are unordered, so don't expect that doing so will have any impact on what happens when you read/compare.

if you throw it's contents into a treemap then this one is sorted

but it's a bad idea to build things based on sorted maps, i have only used it for comparison of deep json trees in tests

I have a suspicion that the reason in this case is code style/ease of reading/nicer diffs

like when you order requires in your ns form

Cursive seems to get confused by an exception I'm throwing

Error printing return value (ExceptionInfo) at compute.data-model.spec-helpers/add2 (spec_helpers.cljc:240).

The problems I was having with slowness/unresponsiveness in recent versions of IntelliJ are a little better after increasing the heap size. I got a low memory warning. The slowness was discussed in an earlier thread here that's now gone. I do have a lot of workspaces open at a time, but it's also possible that recent versions are using more memory. FWIW you can increase heap size with the Heap->Change Memory Settings menu item.

When switching to a particular branch, the entire IntelliJ UI freezes. It appears to have something to do with reading projects.
