I was playing with a little software idea last night and ran into
difficulty.
Actually, I could start an email with that sentence almost every day.
I wanted a little image-processing tool and felt that Photoshop was
massive overkill (also, I donât have it anymore, and itâs expensive).
So I thought: It might be fun to write a little semi-interactive program
with an old-fashioned interface.
This is Mac OS X, fwiw.
The basic logic flow was:
Read an image file
Loop:
Read a command via gets
Parse and execute the command
Display the resulting image
Which works âmostly okâ â but when I do img.display and it
opens a new window⌠the new window (naturally?) has the
focus â I would say âstealsâ the focus from iTerm.
Thinking about this, I suppose it relates more to the window
manager (and maybe ImageMagick and the OS) than to RubyâŚ
Having said that, I wonder if there is a solution to this, other than
constantly re-clicking in my original terminal window?

I firmly believe one should strive daily for this sort of perfection.

This is indeed a property of OS/X (or any other similar display manager,
such as Windows, X, etc)

I havenât written any native applications in ruby, but I imagine that
after you call img.display from your program, you can steal back the
focus in your REPL just before you read a command, but again, Iâm not
sure how youâd do this specifically. Youâd probably need to send some
message to raise the iTerm window. I know you could do something in
AppleScript to do this, but again, not sure what, specifically.
