Hi -- This is a free email account, so I don't have control over what's posted in the footer. You can safely ignore what's there. As far as my questions go:
> I don't see any reference for "term class", unless you mean "urxvt::term > class" which is clearly described in the urxvtperl manpage. Yes, this set of questions relates to urxvt::term class. I don't know that was a joke... so, ha. Good one...? > [...] in X11, applications do not open windows themselves, they > merely ask the wm to open one for them, which then choses desktop etc. I just realized that I'm already using wmctrl to do this, so that's fine. In case anyone else wants to do something similar, here's the syntax: # switch to Desktop 2 wmctrl -s 1 Note that wmctrl starts the desktop increment from zero (i.e. Desktop 1 = "wmctrl -s 0", Desktop 2 = "wmctrl -s 1", etc.). > Urxvt only knows the single command it starts within the terminal window, > it cannot start additional commands (it would be technically possible, > but almost cetrainly very undesirable). How would you open a new window and, for example, send the 'ls' command to that window, then leaving the command line open to await further input? This is desirable functionality in terms of automating the setup of up your working environment. Another example would be something simple like sending a message to the terminal when it opens, like "echo 'Hello My Dear User!'" (or something else). >> ...and the following creates a reference to the 'envv' hash: >> my @envv = $self->envv; > > No, that simply returns all environment variables by value. That was a mistake. I meant to write: my $env = $self->env; If that's incorrect, what is the correct way to set the $envhashref and $rxvtname variables? The documentation gives no further ideas (and if it does, repeating here would be like asking me to read it for the millionth time -- not useful). $term = new urxvt::term $envhashref, $rxvtname, [arg...] An example of how to start a new terminal window and send a command to that window is what would be most useful here, so that I can go ahead and start using urxvt if at all possible. Has anyone done this? It seems like something a powerful application like urxvt would be able to do easily once you know how to do it. Thanks for your help. P.S. I'm also curious about how to resize fonts dynamically, i.e. 'ctrl +' to enlarge the font and 'ctrl -' to decrease the size. There is an extension (called 'font-size') that does this, but it doesn't render the text correctly until you resize the window. Font resizing seems like a feature that an advanced terminal like urxvt would have built-in, so if I missed that in the documentation (or there are other extensions that work like font resizing does in a web browser, for example), please advise... > -----Original Message----- > From: [email protected] > Sent: Sun, 21 Dec 2014 14:24:33 +0100 > To: [email protected] > Subject: Re: Using the The "urxvt::term" Class > > On Sat, Dec 20, 2014 at 09:14:13AM -0800, kario tay <[email protected]> > wrote: >> I wanted to know if there are any resources >> available for understanding and using >> the 'term' class. > > I don't see any reference for "term class", unless you mean "urxvt::term > class" which is clearly described in the urxvtperl manpage. > > I am afraid you need to ask a much more specific question. > >> 1.
