[PATCH] nconf: add vi-style command keys for the menu navigation

[Dmitry Voytik]

Add alternative vi-style keys for the menu navigation:
<j>/<k> for down/up navigation, <C-f>/<C-b> for
page down/up, <g>/<G> for first/last menu item selection
and <l> for entering to a submenu.

Although I am not a fan of this color scheme, it is much more readable
than the previous black-on-blue. Tested in frame-buffer console, in konsole
and in xterm. And queued in my non-official for-next branch.

[PATCH 1/2] nconf: add keybindings for vi-style menu navigation, rewrite help texts

Good starting point, thanks for your initial work.
Here is completion of the work:


>From: Roland Eggner <edvx1@systemanalysen.net>

•  Completed vi-style navigation <k> <j> <l> <h>.  Using <?> <H> instead of
   <?> <h> for help related to current menu entry avoids conflict.

•  Added keybindings <C-n> <C-p> additionally to <C-f> <C-b> for moving pagewise
   down and up.  <C-f> <C-b> is used for characterwise right and left movement
   by libreadline (bash, xfsprogs, bc, gdb, python, ruby, hunspell, mysql,
   sqlite, gnupg, xine-ui, parted …).  Thus pagewise movement by <C-n> <C-p> is
   less confusing than by <C-f> <C-b> for my fingers.

•  Rewrote all help texts.  During several years lazy (incomplete) updates had
   left behind a rather thick layer of dust.  Intentions:
   (1)  Global help called by <F1> should document  _all_  implemented
	keybindings.
   (2)  Different help texts called by <F3> resp. <F8><F1> should be consistent
	with (1) and with implementation:
	•  on plain menu entry
	•  in radiolist window
      	•  in input windows for text, decimal or hexadecimal values
      	•  in filename selection windows <F6> <F7>
      	•  SymSearch specific help called by <F8> followed by <F1>

•  Function keys line:  “Help 2” instead of “Insts” and “ShowAll” instead of
   “Config” should be more intuitiv.

OK, I'll queue these and test this weekend (see my previous reply to Dmitry).

I'm sorry, but this patch does not apply cleanly, neither on-top of
Dmitry's patch, nor on-top of Michal's for-next branch:

Also, the patch is line-mangled, with long lines being wrapped by your
MUA. Could you use git send-email, next time, please?

Care to resend your patch on-top of Michal's for-next branch (and on-top
of Dmitry's patch if needed) ? Or tell me what branch to apply it onto.

Thank you.

Sorry.  Recreated patch versions will follow in replies to this message, the
1st to be applied on vanilla 3.8-rc3, the 2nd to be applied on vanilla 3.2.35.
Unfortunately the patch submitting rules do not allow me to mention this in
subject lines.

Thanks

Re: [PATCH v2 1/2] nconf: add keybindings for vi-style menu navigation, rewrite help texts

[Roland Eggner]

[-- Attachment #1: Type: text/plain, Size: 25107 bytes --]

>From: Roland Eggner <edvx1@systemanalysen.net>

•  Implemented vi-style navigation <k> <j> <l> <h>, based on initial work by
   Dmitry Voytik.  Using <?> <H> instead of <?> <h> for help related to current
   menu entry avoids conflict.

•  Added keybindings <C-n> <C-p> additionally to <C-f> <C-b> for moving pagewise
   down and up.  <C-f> <C-b> is used for characterwise right and left movement
   by libreadline (bash, xfsprogs, bc, gdb, python, ruby, hunspell, mysql,
   sqlite, gnupg, xine-ui, parted …).  Thus pagewise movement by <C-n> <C-p> is
   less confusing than by <C-f> <C-b> for my fingers.

•  Rewrote all help texts.  During several years lazy (incomplete) updates had
   left behind a rather thick layer of dust.  Intentions:
   (1)  Global help called by <F1> should document all  _currently_  implemented
        keybindings.
   (2)  Different help texts called by <F3> resp. <F8><F1> should be consistent
        with (1) and with implementation:
        •  on plain menu entry
        •  in radiolist window
        •  in input windows for text, decimal or hexadecimal values
        •  in filename selection windows <F6> <F7>
        •  SymSearch specific help called by <F8> followed by <F1>

•  Function keys line:  “Help 2” instead of “Insts” and “ShowAll” instead of
   “Config” should be more intuitiv.

Re: [PATCH v2stable 1/2] nconf: add keybindings for vi-style menu navigation, rewrite help texts

[Roland Eggner]

[-- Attachment #1: Type: text/plain, Size: 25104 bytes --]

>From: Roland Eggner <edvx1@systemanalysen.net>

•  Implemented vi-style navigation <k> <j> <l> <h>, based on initial work by
   Dmitry Voytik.  Using <?> <H> instead of <?> <h> for help related to current
   menu entry avoids conflict.

•  Added keybindings <C-n> <C-p> additionally to <C-f> <C-b> for moving pagewise
   down and up.  <C-f> <C-b> is used for characterwise right and left movement
   by libreadline (bash, xfsprogs, bc, gdb, python, ruby, hunspell, mysql,
   sqlite, gnupg, xine-ui, parted …).  Thus pagewise movement by <C-n> <C-p> is
   less confusing than by <C-f> <C-b> for my fingers.

•  Rewrote all help texts.  During several years lazy (incomplete) updates had
   left behind a rather thick layer of dust.  Intentions:
   (1)  Global help called by <F1> should document all  _currently_  implemented
        keybindings.
   (2)  Different help texts called by <F3> resp. <F8><F1> should be consistent
        with (1) and with implementation:
        •  on plain menu entry
        •  in radiolist window
        •  in input windows for text, decimal or hexadecimal values
        •  in filename selection windows <F6> <F7>
        •  SymSearch specific help called by <F8> followed by <F1>

•  Function keys line:  “Help 2” instead of “Insts” and “ShowAll” instead of
   “Config” should be more intuitiv.

OK, now I've had time to test it. Works OK.

However, this patch mixes different things: feature changes, help-texts
rewrite...

Could you split it into multiple patches, each do a single, well-defined
change? See below.

I think we should only retain the more "natural" key bindings: <C-f> and
<C-b> for left/right. <C-p> and <C-n> are not for PAge-Up/Down, but for
previous-in-history and next-in-history (which, IMHO, is not the same
meaning).

However, I wonder how many such *-like keys we should have.

The up/down and Page-Up/Down keys are really trivially understood. It's
been a long while ago they were introduced in vim (rather than using the
oldish hjkl). Readline also understands those arrow-keys keys. So, really,
I wonder what the point of having these new keys is.

This one does indeed give an easier to read, more precise and more complete
help. This should be a separate patch.

Ditto, a separate patch.

I'd suggest that you add the least controversial patches first, and submit
them as four patches:
  - help rewrite
  - labels rewrite (update help accordingly)
  - vi-like keys
  - readline-like keys

(Or the other way around for the last two patches.)

With this patch ordering, each patch is easier to review, the fixes ones
(help and labels rewrites) can be easily applied, and we can discuss the
last two separately.

Thank you!

Yann E. MORIN.

It conflicts with previous behavior that people got used to, though.

Also, please split the patch at least into one part adding the new key
binding and a second part rewriting the help texts.

I'll test and queue in my branch to later push a complete batch to
Michal a litle bit before the next merge window opens.

It will not be before the WE that I will have time to test that.

The <g>/<G> keys are not documented in the help text.
<HOME>/<END> are not, either.

Care to add those and resend, please?

Otherwise, working OK here.

Already documented in previous version and in v2 posted half hour ago:

User interface:
<F1> “Global help“, table starting near line 36.

Source code:
grep -E -n '(First|Last) entry' scripts/kconfig/nconf.c


> Care to add those and resend, please?

v2 based on 3.8-rc3 posted.


Thanks for review.

Ah, so your patch includes Dmitry's changes, right?

OK, thank you! I'll handle the 3.8-rc3 one shortly.

Thank you!
