Russ Cox describes it in this video as more like an “integrating development environment” as in it works with your surrounding operating system rather than an “integrated development environment”

Doesn’t shine as much on Unix as in Plan 9 though. Also no linter or formatter built into or distributed with acme but you probably could get your language’s usual tools to work pretty well with it
