Hello everyone!
I am trying to write a front-end for the command-line archiving
program
"dar" ( http://dar.linux.free.fr/ )
I can read happily from the dar Process.Output but am not managing to
respond using Process.Input
When extracting an archive using the commandline, when dar finds a
file
to be overwritten, it asks if it should be overwritten, to which the
response is [RETURN] key for 'Yes' or [ESC] key for 'NO'. I have
tried
writing both #13 and #27 to Process.Input but it has no effect: the
program just hangs as the Process never stops running and gives no
more
output.
Try writing #10 or #13#10

No, I've already tried that, and checked the dar source: it is
definitely looking for one byte of input: #27 or '/n', which is #13.
IIRC newlines on unix are #10
This is true, but unfortunately not the solution
Is it possible that it is ignoring stdin because it is not being run
from a terminal?
Thats possible too. But maybe it isn't reading stdin at all.
I was beginning to suspect that this was possible (*sighs*). Looking
again at the dar source I found the following:
// we do not use anymore standart input but open a new descriptor
// from the controlling terminal. This allow in some case to
keep use
// standart input for piping data while still having user
interaction
// possible.
Apart from the fact that it doesn't use stdin for interaction I'm afraid
this is all a bit above me.
I suspect that this means that I am not going to be able to interact
with dar using TProcess. Is this correct?
Thanks for your help, Marc
Malcolm
