[SOLVED] GUI for multi-line text input for bash script

Postby hiltuspeke » 2016-11-16 15:45

Hi.

I've written very simple bash script to read user input for a variable and then echo that variable to a text file for later use.

I want this script to work on a graphical interface without a terminal window, so currently I'm using Zenity to read the input. It is working marvelously, but the text entry dialog in Zenity only has one line. I need to have a input dialog that allows me to input a string of text with line breaks in it. I couldn't find a way around this in the documentation of Zenity, which leaves me to the conclusion it simply is not possible with Zenity.

Is there another, similar software I could use? Of course there is dialog, but as mentioned, I'd like to stay graphical. I found some ~10 years old discussion online about this very same issue, and they recommended using gtkdialog, but I can't find it in the repos anymore.

And yes, I could theoretically just add -e -switch for echo in my script and use \n instead of enter when writing the input, but that is far from easy-to-use and minimalism I'm aiming for.

What should I use?

Yad and so on may be good.
Code: Select all
# PREPARATION - install dialog and xterm
apt update
apt install dialog xterm
# END OF PREPARATION

touch /PATH/TO/FILE
xterm -e "dialog --editbox /PATH/TO/FILE 0 0"

Thank hiltuspeke for telling the option "--text-info --editable" :)

It turned out that this is indeed possible in Zenity.

I found it out while reading the documentation for YAD.
In YAD it is possible to input many lines using Text-info dialog and mark it editable:
Code: Select all
--text-info --editable


After this success in YAD I tried the very same syntax for Zenity, and it indeed is possible with the very same syntax. Case closed.
(Now that I have YAD compiled, I may still stick to that, as it uses GTK+2 and looks nicer on my Mate setup. )
