GNOME Terminal: a little something for Fedora 29

Can you spot what that is?

GNOME Terminal: separate menu items for opening tabs and windows

Astute users might have noticed that the GNOME Terminal binary distributed by Fedora has separate menu items for opening new tabs and windows, while the vanilla version available from GNOME doesn’t.

With separate menu items

This has been the case since Fedora 25 and was achieved by a downstream patch that reverted two upstream commits.

Without separate menu items

I am happy to say that since version 3.28 GNOME Terminal has regained the ability to have separate menu items as a compile time option. The gnome-terminal-server binary needs to be built with the DISUNIFY_NEW_TERMINAL_SECTION pre-processor macro defined. Here’s one way to do so.

GNOME Terminal 3.28.x lands in Fedora

The following screenshots don’t have the correct colours. Their colour channels got inverted because of this bug.

Brave testers of pre-release Fedora builds might have noticed the absence of updates to GNOME Terminal and VTE during the Fedora 28 development cycle. That’s no longer the case. Kalev submitted gnome-terminal-3.28.1 as part of the larger GNOME 3.28.1 mega-update, and it will make its way into the repositories in time for the Fedora 28 release early next month.

The recent lull in the default Fedora Workstation terminal was not due to the lack of development effort, though. The recent GNOME 3.28 release had a relatively large number of changes in both GNOME Terminal and VTE, and it took some time to update the Fedora-specific patches to work with the new upstream version.

Here are some highlights from the past six months.

Unified preferences dialog

The global and profile preferences were merged into a single preferences dialog. I am very fond of this unified dialog because I have a hard time remembering whether a setting is global or not.

Text settings

The profile-specific settings UI has seen some changes. The bulk of these are in the “Text” tab, which used to be known as “General” in the past.

It’s now possible to adjust the vertical and horizontal spacing between the characters rendered by the terminal for the benefit of those with visual impairments. The blinking of the cursor can be more easily tweaked because the setting is now exposed in the UI. Some people are distracted by a prominently flashing cursor block in the terminal, but still want their thin cursors to flash elsewhere for the sake of discoverability. This should help with that.

Last but not the least, it’s nice to see the profile ID occupy a less prominent position in the UI.

Colours and bold text

There are some subtle improvements to the foreground colour selection for bold text. As a result, the “allow bold text” setting has been deprecated and replaced with “show bold text in bright colors” in the “Colors” tab. Various inconsistencies in the Tango palette were also resolved.

Port to GAction and GMenu

The most significant non-UI change was the port to GAction and GMenuModel. GNOME Terminal no longer uses the deprecated GtkAction and GtkUIManager classes.

Blinking text

VTE now supports blinking text. Try this:

  $ tput blink; echo "blinking text"; tput sgr0

If you don’t like it, then there’s a setting to turn it off.

Overline and undercurl

Similar to underline and strikethrough, VTE now supports overline and undercurl. These can be interesting for spell checkers and software development tools.

Emojis in VTE

It’s been one of those weeks when gnome-terminal and vte keep stumbling on some really weird edge cases, so it was a happy moment when I saw this on Fedora 27 Workstation.
