no output on command line

there is no output 👍

$ cat t.glu

let prelude = import! "std/prelude.glu"
let io = import! "std/io.glu"

let run x : () -> IO () =
    io.println "gluon (:h for help, :q to quit)"
run

$ ./target/debug/gluon t.glu

Thanks for reporting! It appears that running files from the command line has regressed so that it no longer runs IO expressions. Fairly simple to fix but I will do some cleanup of the API being used as well.

Note that you actually have a bug in the example you posted. The run function must be called as well or else the IO action won't be executed (you only return the function run as it is currently).

let prelude = import! "std/prelude.glu"
let io = import! "std/io.glu"

let run x : () -> IO () =
    io.println "gluon (:h for help, :q to quit)"
run ()
