Hyperlinks (a.k.a. HTML-like anchors) in terminal emulators

Most of the terminal emulators auto-detect when a URL appears onscreen and allow to conveniently open them (e.g. via Ctrl+click or Cmd+click, or the right click menu).

It was, however, not possible until now for arbitrary text to point to URLs, just as on webpages.

In spring 2017, GNOME Terminal and iTerm2 have changed this.

GNOME Terminal is based on the VTE widget, and almost all of this work went to VTE. As such, we expect other VTE-based terminal emulators to catch up and add support really soon. Other terminal emulators are also welcome and encouraged to join!

## Purpose: create a partial Rubygems mirror on Debian (7 AKA wheezy)
## Design goal: no system wide gems other than Debian packages

# make sure bundler, ruby-builder (required for generate_index) + rubygems-integration (required for gem<->builder integration) are available:
% sudo apt-get install ruby-bundler ruby-builder rubygems-integration

# We use gem-mirror (http://rubygems.org/gems/gem-mirror / https://github.com/YorickPeterse/gem-mirror), so
# install gem-mirror gem itself (requires ruby >=1.9) in local directory for execution via bundler:
% cat Gemfile
source 'https://rubygems.org/'

The instructions were tested on a Lenovo X1 Carbon 5th Gen (X1C5) on Arch Linux but should be applicable to other Lenovo models and Linux distributions.

BACKUP YOUR DATA! I created a bootable Ubuntu Image like this:

$ sudo sh -c 'curl --location --silent --fail "http://releases.ubuntu.com/18.04/ubuntu-18.04.1-desktop-amd64.iso" | pv > /dev/<your-usb-drive>'
# note that pv is only there to show progress, it is perfectly fine to redirect curl to the usb drive directly.

then I booted from this drive by pressing F12 on reboot and dumped my NVMe disk to an external hard drive like this:
