Xdialog make a ratiolist from a Directory listing?

[HoerMirAuf]

Hi Volks.

I am a novice in scripting bash scripts and/or Xdialog or gtkdialog

I want to make a ratiolist, where i can choose on of all folders in a directory. I am interested in to do this in Xdialog also in gtkdialog

i know a little bit about "ls -d */" and about to build the ratiolist. But how can i make now a ratiolist from the result from "ls -d */" ??

Maybe anyone can explaine me or give me a hint or an example?

Here is an example from don570's bulldog finder (I think).

It gives a small gtkdialog gui of all mounted drives.

Maybe a good starting point ?

Remove the fake '.gz' and make executable.

Code: Select all

#!/bin/sh

for ONEFILE in /path/*; do
    [ -d ${ONEFILE} ] || continue
    DIALOGLIST="${DIALOGLIST} ${ONEFILE} - off"
done
Xdialog --checklist "Directories" 0 0 5 ${DIALOGLIST}

[MochiMoppel]

Here a slight variation of PANZERKOPF's code:

Code: Select all

#!/bin/sh

DIRECTORY="/root"
for ONEFILE in "$DIRECTORY"/*; do 
     [ -d $ONEFILE ] || continue 
     DIALOGLIST="${DIALOGLIST} ${ONEFILE} ${ONEFILE##*/} off"
 done 
ANSWER=`Xdialog --no-tags  --stdout --radiolist "Subdirectories in $DIRECTORY" 30 30 5 ${DIALOGLIST}`
Xdialog --msgbox  "$ANSWER"  5 30

Haven't figured out yet how to accomodate code for directory names containing spaces.

Why not just use:

Code: Select all

Xdialog --dselect $PARENTDIR 0 0

[MochiMoppel]

Why not just use...

Spec violation! No radiobuttons...

[technosaurus]

The result is the same, radio buttons only allow one selection... the same as dselect... except that the intention is more clear with dselect

A radiolist can be done:

Code: Select all

A='Xdialog --no-tags --radiolist "select something" 0 0 9 '
for x in *;do
   [ -d "$x" ] && A="$A \"$x\" \"$x\" 0 "
done
RESULT=`eval $A`

...but I don't find it as appealing as a simple -dselect

[PANZERKOPF]

Why not just use:

Code: Select all

Xdialog --dselect $PARENTDIR 0 0

I presumed HoerMirAuf wants to choose not only one but number of directories at same time, therefore I recommended a checklist instead of radiolist.

... I have no idea what a "ratiolist" is either or "on" of all folders ... but I assumed "radiolist" and "one".... honestly Zigbert's pprocess2 is a better looking example for gtkdialog selections than the Xdialog --radiolist

[MochiMoppel]

And now the ultimate challenge :

But how can i make now a ratiolist from the result from "ls -d */" ??

Usefulness apart, at least it could serve as a blueprint for reading any external list into a radiolist :

Code: Select all

ls -d */ > /tmp/list
A='Xdialog --no-tags --stdout --radiolist "select something" 0 0 9 ' 
while read x; do
	A="$A "$x" "$x" 0 " 
done < /tmp/list 
RESULT=`eval $A`

while read x; do
	A="$A "$x" "$x" 0 " 
done < /tmp/list 
RESULT=`eval $A`

That does the same thing as my example except that it requires an extra external binary, and superfluous file write and read

ls -d */ is roughly the same as echo */ but echo is a shell builtin (much faster)
rather than writing to a file as command >file (slow) you can do VAR=`command` and then you can echo $VAR | through a pipe or use <<< $VAR redirection

BTW, my example needed --stdout (Xdialog has some stupid defaults) ... and the [ -d ... ] bit could be replace with a */

Code: Select all

A='Xdialog --stdout --no-tags --radiolist "select something" 0 0 9 '
for x in */;do A="$A "$x" "$x" 0 ";done
RESULT=`eval $A`

... I have no idea what a "ratiolist" is

The assumption radiolist is right.

In Franconian dialect (HoerMirAuf's Location Würzburg is the capital of Lower Franconia) the pronounciation of d and t are swapped, same for b and p when Franconians want to speak "Hochdeutsch". This phenomen has been stuff for some sketches. e.g.:

Have fun

Thanks for correction.
If he wants to choose only one directory, an example shown by technosaurus (--dselect) is simpler and better for this purpose.

[HoerMirAuf]

Damn guys!

Thank you so much for your many replies. I have to check them all out.

Maybe a little mor explain to my request:

I want only choose one Directory from a lot.
It is not neccesary to solve this with "ls -d */" ... this was the only idea, i have had.

But i cant take a "Xdialog -deselct" box, because there are subfolders in the Directory i want to choose ... and with deselect this subfolders are also selectable ... ore not?

Ok ... now i will try out your suggestions

Thanks a lot !

Yes, it works like filemanager, You can browse directory tree and enter in
any subdirectory.

[HoerMirAuf]

hmmmm

Code: Select all

A='Xdialog --no-tags --radiolist "select something" 0 0 5 '
for x in *;do
   [ -d "$x" ] && A="$A \"$x\" \"$x\" 0 "
done
RESULT=`eval $A`

this is just a very nice solution... Thank you all a lot!

But eval will give back the result only in a terminal output. Why eval dont write it to the variable "RESULT" ??

[PANZERKOPF]

IMHO Xdialog prints a result to stderr by default. It needs additional option "--stdout"
for printing to stdout.

Change first line of code:

Code: Select all

A='Xdialog --stdout --no-tags --radiolist "select something" 0 0 5 '

Hi Panzerkopf.

Thanks a lot!! ... It works ... why i havent seen that by myself?

You can also use the 2>&1 construct to re-rout the stderr to stdout

A while back, on puppy 4.3.1, I wrote a thing that needed to ask a lot of questions via Xdialog. I discovered to my horror that after so many calls to Xdialog in a script, it would start to fail. As a result, I ended up recoding it to use just "dialog" and pop up a terminal. Hopefully this problem won't plague people today.
