[ir] webif screen keyboard control

[Oatcake]

I often use a laptop to control my humax via the WebIf (using the ir package).

For those who are not familiar please see the wiki page "WebIf_Remote_Controller" (I am not allowed to post a link)

I've found it very useful to extend this screen with keyboard shortcuts. For example I've mapped the laptop's cursor keys to the Humax "D pad" navigation buttons and find this quicker than using a mouse/ touchscreen. This works when the browser is showing the remote AND the browser has the keyboard input focus.


At the bottom of this post are the code additions. Maybe they could be considered for inclusion in the next package release if people are interested? If included then the screen itself should probably be changed to show the shortcuts.

Shortcut keys...

Navigation

Key	Remote
Cursor keys	D pad movement
Return	OK
Shift + cursor up/ down	P+ / P- (useful for fast navigation in the media list)

Playback

p	Play
Space	Pause
i	info
Shift + cursor left/ right	Rew/ FF
Ctrl + cursor left/ right	skip back/ skip forw
b	go to bookmark
shift+b	add bookmark

General

0-9	0-9
escape	back
shift+escape	exit
f1	media
f2	guide
tab	opt+
Colour buttons (4 adjacent keys) q, w, e, r	red, green, yellow, blue

The code additions are in /mod/webif/plugin/ir/script.js and there are a few existing lines shown for context (near the top of that file)...

var signalarray = ['ZERO', 'ONE', 'TWO', 'THREE', 'FOUR',
           'FIVE', 'SIX', 'SEVEN', 'EIGHT', 'NINE'];

$('button').button();

    send(encodeURIComponent(cmd), '#xmit' + xmit);
    e.preventDefault();
}

$(document).keydown(function(e){
    // Handle cursor keys...
    if (e.keyCode==38) { sendK(e.shiftKey ? 'P+':'UP', 2, e); }

    //  number keys (not number pad)...
    else if (e.keyCode>=48 && e.keyCode<=57) { sendK(signalarray[e.keyCode-48], 1, e); }
    //  number pad numbers...
    else if (e.keyCode>=96 && e.keyCode<=105) { sendK(signalarray[e.keyCode-96], 1, e); }

@af123
In addtion to this, would it be possible to make the command line ir utility case insensitive?
It's easier to type "ir mute" than "ir MUTE" but the former just generates a needless error.
It's just a simple case of replacing strcmp() with strcasecmp() and strncmp() with strncasecmp().

 

[af123]

Give `ir 1.14` (beta) a try for both of the above.

Both working well, thanks.
If I may suggest some additions to @Oatcake 's above list as well to fill in a few obvious gaps:
l - List
m - Mute
u - Menu
[ - Vol. down
] - Vol. up
s - Stop

Done - will be available in ir 1.15
