Hello everybody,
Some time ago I wrote a perl-module to make it easier for me to read and
encode audio-cds. I had done so, planning to write a GUI in Perl/Tk
later.
A few days ago, "Mastering Perl/Tk" arrived, I started playing around
with simple excercises, until I felt like I knew what I wanted the GUI
to be like.
In fact, it mostly works now. And, by the way, I was just amazed to see
how quickly I got it working. Tk is very easy to use, yet powerful.
There is just one thing I had all forgotten about, I cannot display the
progress of reading/encoding the CD via Tk.
When I call the GUI from the command-line, the output of the programs
reading and encoding the CD (cdparanoia, lame, oggenc) goes to the
terminal.
First I thought of a progressbar, which would look nice, but calculating
how much of the encoding is done already seems like too much work.
Plus, cdparanoia/lame/oggenc format their output very nicely, so I
though of "capturing" that output and display it via e.g. a
ROText-widget.
I'm not sure how to do this, though. ;-/ Especially, I don't know if
this can be done without major changes to the module. As of now, the
programs are called via system().
So far, both the module and the GUI are rather simple. If possible, I
would like to keep it that way.
I think I remember it is somehow possible to redirect STDOUT (without
doing so at the shell level). Can this be done in a way so that this
redirection works for the programs called via system() as well?
Thanks a lot,
Benjamin
