Is anyone able to help me with this?

1. When I run stack exec unison it doesn't recognise the new method.

main : '{IO, Exception} ()
main = do
  printLine "hello"
  printLine (getEnv "HOME")
  printLine getEnvironment()

results in

  I couldn't figure out what getEnvironment refers to here:
  
      5 |   printLine getEnvironment()
  
  I found a term in scope with a similar name but a different type. Was this what you wanted?
  
  getAndIncrement : Ref {IO} Nat ->{IO} Nat

2. I want to add tests to io.md but I don't know how to get unison running in such a way that that code works. For example where does the io2.IO ability come from. Apologies if this is obvious but I've only started learning Unison this week 😅

You need to give the new built-in a name. This should be done in base, but if you want to test it locally you can use the alias.term command in ucm. alias.term ##IO.getEnvironment.impl.v1 IO.getEnvironment. Then you should be able to reference it in your code as IO.getEnvironment.

Thanks @skykanin . I'm able to see the see the changes locally now!

Remaining Problems

1. How do I add the new function to base?
2. Running stack exec unison transcript unison-src/transcripts/pretty-print-libraries.md wipes out the changes I made by hand to pretty-print-libraries.output.md.
3. Running stack exec unison transcript unison-src/transcripts-using-base/all-base-hashes.md fails with an error saying No results..
