Esc+Esc+right (meta-right) not being detected?

python > bpython

Nicholas Sweeting (S'14): @tom Ballinger do you know how to get option + arrow key word jumping in bpython?

Nicholas Sweeting (S'14): In ipython you can press option + left arrow and jump a word to the left

Nicholas Sweeting (S'14): same for right

Nicholas Sweeting (S'14): and ctrl + left to get to the beginning of the line

Tom Ballinger: works on my machine™

Tom Ballinger: oh not control though

Nicholas Sweeting (S'14): hmm odd probably a terminal setting then

Nicholas Sweeting (S'14): do you have "Use Option as Meta Key" turned on under Profiles > Keyboard ?

Nicholas Sweeting (S'14): nevermind turning that off doesn't seem to affect it

Tom Ballinger: left option as +Esc, right option as Meta

Tom Ballinger: both of those work for me

Tom Ballinger: Huh and normal option works for me too

Nicholas Sweeting (S'14): weird, I don't have any strange configs set up

Nicholas Sweeting (S'14): tried installing a fresh version too

Tom Ballinger: the one that on a mac writes alternate characters

Nicholas Sweeting (S'14): bpython version 0.15 on top of Python 3.5.2

Tom Ballinger: ctrl-left and ctrl-right don't do anything though

Tom Ballinger: You might try python -m curtsies.events

Nicholas Sweeting (S'14):
b'\x1b\x1b[D'
<Esc+LEFT>

b'\x1b'

b'\x1b[C'

b'\x1b[5D'

Tom Ballinger: are they getting double-escaped maybe?

Nicholas Sweeting (S'14): it works fine in ipython and fish

Tom Ballinger:
'\x1b[1;9D'

<Esc+LEFT>

'\x1b[1;9C'
<Esc+RIGHT>
is what I get, is that output above from just hitting it once?

Nicholas Sweeting (S'14): yup

Nicholas Sweeting (S'14): I'm not in tmux or anything either

Nicholas Sweeting (S'14): hold on lemme check my keyboard replacements to make sure I'm not inserting any weird chars

Tom Ballinger: So we need to recognize \x1b\x1b[D as ESC+Left

Tom Ballinger: Oh but it did that one, we just need to at the Right one? Is option left working in bpython, but not right?

Nicholas Sweeting (S'14): neither works right now

Tom Ballinger: Maybe it's an escape key timing thing, both of

(b'\x1b\x1b[C', u'<Esc+RIGHT>'),
(b'\x1b\x1b[D', u'<Esc+LEFT>'),
are in there

Nicholas Sweeting (S'14): what I can do for now is just add something in keyboard replacements to send the codes it's expecting

Nicholas Sweeting (S'14): since it seems like it's only happening to me, I don't see any stackoverflow questions or anything on this

Nicholas Sweeting (S'14): ok I mapped Ctrl + left to \001 (ctrl+a) and Ctrl + right to \005 (crl+e) and that got jump to beginning of line and end working

Tom Ballinger: @nicholas Sweeting (S'14) Does the option stuff work in new (>5.0.0) IPython? If so I can look at Prompt Toolkit

Nicholas Sweeting (S'14): it works fine in ipyhton 5.0.0

Nicholas Sweeting (S'14): let me install master branch to get a newer version

Tom Ballinger: Is this on a macbook? And does it work in Terminal.app? wondering if there's a setting I can change to reproduce

Nicholas Sweeting (S'14): macbook with stock terminal app

Nicholas Sweeting (S'14):

b'\x1b\x1b[D'

<Esc+LEFT>

b'\x1b'

b'\x1b[C'

Nicholas Sweeting (S'14): option left and option right from python -m curtsies.events with 'User option as meta key' turned on

Nicholas Sweeting (S'14): with "use meta as option key" turned off it only sends:

---

b'\x1b[D'

b'\x1b[C'

Tom Ballinger: That one works in bpython presumably

Nicholas Sweeting (S'14): nope neither work

Nicholas Sweeting (S'14): which is odd

Nicholas Sweeting (S'14): jumping by word only works in fish and ipython with "use option as meta key" turned on

Nicholas Sweeting (S'14): but bpython wont word jump with it set either way

Tom Ballinger: Based on the curtsies.events output it looks like it's identifying Esc+Left just fine

Nicholas Sweeting (S'14): doens't work in bpython-curses or bpython-urwid either, but I assume those both use curtsies now anyway

Tom Ballinger: No bpython-curses is plain curses, but then that key never did anything there

Tom Ballinger: I'm pasting all this in a Curtsies issue, let me know if you think of some weird keyboard thing later

Tom Ballinger: OH and maybe update curtsies, but unlikely that matters

Fixed by ? (uninstalled bpython and curtsies, reinstalled, then is worked)
