mc handles Shift+Fxx-keys incorrectly on OSX

[metalim]

All Shift+Fxx combinations are shifted right by 2 keys: Shift+F4 function called from Shift+F6, Shift+F6 function - from Shift+F8, etc.

Pressing F6 - Move dialog is open - correct
Pressing Shift+F6 - New File is opened for editing (function of Shift+F4) - incorrect.

OSX 10.8.1

Looks like duplicate of #367.

[metalim]

Could you cooperate with brew team to fix the issue?

[metalim]

Checking mc formula I see following:

depends_on 'pkg-config' => :build
depends_on 'glib'
depends_on 's-lang'

[andrew_b]

What is the previous version of mc where shift-fx keys work correctly for you?

[metalim]

None I can remember.
It was like that for at least a year. Before that I had no mac.

[andrew_b]

I think, you should consult with Egmont Koblinger (egmont at gmail dot com). Не is Mac user (for example, #2689) and it looks he don't have this problem.

Are you use xterm?

[metalim]

I use regular Terminal application.
declare -x TERM="xterm-256color"
declare -x TERM_PROGRAM="Apple_Terminal"
declare -x TERM_PROGRAM_VERSION="309"

[egmont]

Sorry but I no longer have access to Mac :(

[angel_il]

so...
1) in your "regular Terminal application" run 'cat'
2) press F6, S-F6, F4, S-F4, you must see:

^[[17~    (F6)
^[[17;2~  (Shift-F6)
^[OS      (F4)
^[[1;2S   (Shift-F4)

if you see something else - you need 'Learn keys'.

[metalim]

$ cat
F4: ^{[OS
Shift-F4: *beeps* - doesn't print}

F5: ^{[[15~
Shift-F5:} [[25~

F6: ^{[[17~
Shift-F6:} [[26~

"Learn keys" does not allow to bind Shift-F1..F4 keys, as they just beep instead.
Binding Shift-F5..F10 to F15..F20- works fine.

[metalim]

Found out why.
In Terminal preferences there is default binding of most non-character keys.
Shift-F5..F12 are bound to \033[25..34. And Shift-F1..F4 are not bound at all.

[angel_il]

try xterm

[metalim]

There's no xterm in OSX 10.8 (Mountain Lion). X11 support was dropped.
$ xterm
-bash: xterm: command not found

The CNET article says that OS X will redirect you to the XQuartz project.
Not exactly "dropped". For the rest, I'll not use Wikipedia as a source
of information.

I've got Leopard and Mountain Lion - Terminal's behavior here doesn't seem to have
changed noticeably (it's always been partial).

In ncurses, the terminfo entry for Terminal has been one of the "nsterm" flavors.
Comparing nsterm-256color versus xterm-256color, infocmp produces 115 lines of
difference. Not close. It would be nice if Apple chose to document their work.
