Menu programming

Oviwan — Mon, 19 Dec 2005 09:30:07 GMT

Hi @ll,

what is the best way to programm a menu like the SAM. in which language is SAM programmed?

I prefer Perl or KSH. exists in Perl a module for a menu.

I saw in KSH exist something like:

select what in "Point1" "Point2"; do
case $REPLY in
1)
echo "foo bar"
break
;;
2)
echo "foo bar 1"
break
;;
esac
done

but exist something who looks more professional than that?

Thanks & Regards

Hi,

If you add a new in SAM, it is shell script based.

Or do you mean a curses oriented menu?

For Sam I believe, it is mainly in C, only a few parts are scripts.
it uses a undocumented library called libObam which does curses or X11 depending if DISPLAY is defined. In any case it is not usable

Thanks @ll

@Geoff: that's what I searched

the dtksh is also nice, but i need a textbased menu. I found this thread for dtksh:

has someone an idea whether exists also something in perl?

Regards

default perl is not having switch case statement as like shell prompt. If you want text based on terminal then you can go with case;do done statements itself.

You can use Perl with add-on modules to program menu driven apps. Check www.cpan.org for more information

Hi,
if you are interested I use a menu driveen created by awk. It's a general purpuose: you write in a file the line you want to see in teh menu and the associated command and nothing else.
Let me know if you want it and I'll attach.
(I'd like to avoid to attach unuseful scripts)

HTH,
Art

Hi All,

Just a remark,

if you press space it toggles the line.
If you want to suppress that feature just comment the " ") case in the switch.
I saw too that the "tput cnorm" is not the right value to clear the bold mode, It is better to use "tput sgr0" to clear all the atributes at its place.

Also, the trick used it to set the non canonical mode with a timeout of (200ms) time=2 and min=1 (at least a charactere).
Sometimes it doesn't work as expected, so raise min to 3.
stty -icanon -echo min 3 time 2 ;
This will wait for 3 characteres or a inter timeout of 200ms

You could check out the "keysh" shell. It is somewhat programmable. Though it doesn't present a menu, it does use function keys to select tasks. Do a "man keysh" for more info.
