Allowing to navigate through code by ctrl+arrows

[ikanobori]

Normally, it's possible to navigate through text in terminal (and almost any place) by using ctrl+left/right arrow. In BPython that doesn't work.

https://bitbucket.org/bobf/bpython/pull-request/49/add-another-sequence-that-can-be-ctrl-left/diff should fix this.

@thomasballinger, ctrl-left and ctrl-right do not seem to work for me. On OS X 10.9, I get D and C respectively instead with bpython-curtsies. With plain bpython, those key combinations don't do anything at all.

bpython-curtsies (now in trunk, no release yet) has ctrl-left, ctrl-right, meta-b and meta-f.

Ah, I see. So you're talking about readline's M-b and M-f (backward-word and forward-word).

You can jump until the next underline too. For example my_long_mehtod_name: to reach the typo you would need a lot of key pressings without ctrl+arrow. In Java IDEs, for instance, this behavior is tweaked to work well with camelCase name convention. It's a lot useful when you get used to.

To jump a word at a time.

Maybe I'm just missing something but why would you want to navigate with Ctrl+Left/Right if you can just navigate with Left/Right?

This once again no longer works. I'm not sure what changed, but it still works fine in bash so I'm guessing something changed in bpython-curtsies. I am getting 5D for control-left and 5C for control-right.

[thomasballinger]

Thanks @myint. Would you either 1) update curtsies and try the keys with python -m curtsies.events, or 2) try ctrl-v control-left in bash and post what you get?

I'm about to change over to explicitly named keys in bpython-curtsies instead of writing out the actual byte sequences, which should mean some improvement to this process - we'l be able to add missing key combinations to bpython-curtsies to add missing keys to bpython.

keylog.txt:

b'\x1b[1;5D' is called control-left
b'\x1b[1;5C' is called control-right

Thanks

This is probably working now, but I can't test it.

[myint]

Yeah, it works. Thanks.

Actually, it did work several hours ago. But I just tried upgrading both bpython and curtsies to master and now only control-left works. control-right does nothing. Also control-u no longer deletes the line.

It looks like the source of the regression is something in bpython. Testing on another machine that I did not pip upgrade, I see that upgrading to the latest curtsies master works fine. It is only when I also upgrade bpython to the latest master that I see the above problem.

Just fixed control-u, thanks for catching that. Looking into control-right
now.

Thank you very much for that fix!
