In my current Arch Linux installation, I decided to use a window manager called i3. It's really awesome and it comes with a really lightweight terminal emulator called urxvt. It's very minimal and I lked it but when I tried to copy-paste text from one terminal to another, I wasn't able to.

However, thanks to the internet, I did some research and figured a way out.

1. Install xClip

First, you need to ensure that you have installed the xclip package, which will be used to copy-paste text in the emulator.

Type the following command to install the package:

pacman -S xclip

2. Activate Clipboard using Perl

Now, you have to paste these custom commands into your clipboard file, which is found in /usr/lib/urxvt/perl directory:

# paste selection from clipboard
sub paste {
     my ($self) = @_;
     my $content = `/usr/bin/xclip -loop 1 -out -selection clipboard` ;
     $self->tt_write ($content);
}

# copy text to clipbard on selection
sub on_sel_grab {
     my $query = $_[0]->selection;
     open (my $pipe, '| /usr/bin/xclip -in -selection clipboard') or die;
     print $pipe $query;
     close $pipe;
 }

3. Modify your .Xresources

Add these keybindings to your .Xresources file:

URxvt.keysym.Shift-Control-V: perl:clipboard:paste
URxvt.iso14755: False
URxvt.perl-ext-common: default,clipboard

After adding it, refresh your .Xresources settings:

xrdb -merge .Xresources

Reboot your terminal and try selecting some text from your terminal using your mouse and paste it using Ctrl+Shift+V and it should work!

That's it! Enjoy 😃
