ruby/GTK : Embedded terminal or redirecting process output

[Mickael Faivre-Macon]

Hi,

Using ruby-gnome2 (gtk) I'd like to embed a terminal in a window, or
redirect the output of a child process into a text editor.

Something like
sbtn.signal_connect("pressed") {
system('ls')
}

.... launch the command 'ls' but is not portable and I don't know how to
redirect the output into a gtk text editor, not in the original
terminal window.

Something like
sbtn.signal_connect("pressed") {
lsproc = IO.popen('ls')
p Process.waitpid(lsproc.pid)
p $?
}
.... is portable, but still does not redirect the output.

Could someone give me a pointer to begin with ?

Thanks,
Mickael.

If you just want to get a list of files in a directory, Ruby
provides the portable Dir#entries method.

I don't know how to
redirect the output into a gtk text editor, not in the original
terminal window.

I'm sure the gtk text editor has some #append or #insert method
which lets you add text to it. Use that.

Something like
sbtn.signal_connect("pressed") {
lsproc = IO.popen('ls')
p Process.waitpid(lsproc.pid)
p $?
}
... is portable, but still does not redirect the output.

IO.popen('ls') do |f|
puts f.read
end


If you want to "pipe" some data to the subprocess:

request = "i want ice cream!"

IO.popen('cat', 'r+') do |f|
f.write request
f.close_write

response = f.read
puts "cat said: #{response}"
end

What about Ruby/VTE? Ruby/VTE is included in Ruby-GNOME2 since
0.15.0.
