Backwards text?

[refi64]

First thing: this is AWESOME!

Now, as this is targeted towards terminal destruction, I was wondering about the chance of adding something involving Unicode RTL. Something like:

• Whenever the user types a letter, the cursor will move to the left so that the input comes out backwards. Jitter already kind of does this.
• Everything printed to the terminal will be backwards. This is the cool part.

Thoughts?

Sorry for the late response. For some reason github doesn't email when a new issue is added.

This is an interesting idea! I'll have to play around with it and see what it looks like. Or feel free to submit a PR and I'll check it out :-)

Hmm, printing that character actually just outright crashes my terminal in python (iTerm2 on OSX). Can you try this in a python shell and tell me what happens for you?

print u'\202e' + 'Testing'

So:

• Is that supposed to be u\u202e?
• I can't test it right now on a real terminal, as I'm on a phone, but:
  • PyPy.js's web REPL freezes for a second and throws a UnicodeEncodeError.
  • Ideone gives the same result.
  • repl.it works.

It seems to depend on whether the output console supports Unicode in general. I love Python, but this Unicode mess sucks... :O

Also: only that line of text is reversed. The following line returns to normal.

Interesting -- the version you posted does seem to work on the online repl:

print(u'\u202e' + "This is a test")
‮This is a test

But still crashes my terminal. It looks like it even works in the github comments though. If I try to type after the invisible character there everything comes in reversed. I really like this idea; I just don't want it to crash peoples' terminals.

@dellis23 In Bash, that seems to do nothing. :(

Maybe there can be a workaround. I'll look into it!
