Arturo is a very interesting programming language that I am experimenting with. It is similar to Red and Rebol, but with a smaller collection of library functions. (A positive for me!).
Here is the Win binary, around 8 MB.
Unzip anywhere, and then run artide.exe. Also have a look at the help file. Bear in mind that your system might warn you about such binaries, and/or prevent a download. You should always take note of such warnings.
Here is an example of pretty-printing, and incidentally detecting an error that Arturo does not highlight well.
Original file: print "hello World" a: (3 + d )) [ aaa [ bbb ccc ] ] Prettified file: print "hello World" a: (3 + d )) [ aaa [ bbb ccc ] ] Message: Warning - non-fatal: Possible unbalanced round () in line 2
The pretty-printer can be run without the editor, if you wish.
