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

[ Update 2020-05-31: I won't be maintaining this page or responding to comments anymore (except for perhaps a few exceptional occasions). ]

---

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.

Synchronized Output

Synchronized output is merely implementing the feature as inspired by iTerm2 synchronized output, except that it's not using the rare DCS but rather the well known SM ? and RM ?. iTerm2 has now also adopted to use the new syntax instead of using DCS.

Semantics

When rendering the screen of the terminal, the Emulator usually iterates through each visible grid cell and renders its current state. With applications updating the screen a at higher frequency this can cause tearing.

This mode attempts to mitigate that.

Private Mode for In-Band Window Resize Notifications

Terminal emulators typically receive window resize events by installing a signal handler for the SIGWINCH signal. Handling of these signals can create challenges due to their inherently racy properties. Resize events must be synchronized with other application state in a safe manner.

Standard control sequences exist to query the current terminal size from the terminal and receive an in-band control sequence with the window size. However, this system requires polling - which is not ideal. Usually, SIGWINCH handling
