[TUT] How to remove whole desktop enviroments with single command

Many people always ask these kinds of questions, but here is the command replace mate- word with xfce-,kde- etc..:
Code:
pkg delete `pkg info -q | grep mate-`

Note that KDE packages names contain "plasma5", so run this command with plasma5- after you ran kde-.

So to break it down, pkg-info works with installed packages, while pkg-search works with packages in repo. By combining the output of pkg-info with pkg-delete we can achieve this.

Beside the already said (at least you've got to check the output of the query command before executing) the de-installation is incomplete: You need also a pkg autoremove afterwards to get rid of many, many packages that are installed as a dependency of those packages…

Anyway i think pkg needs to consider package grouping. To solve these problems especially.

No. There's a package "x11/mate" - if you install it, it raises alll other packages as dependencies. Just deinstall it, and a pkg autoremove removes all related packages. Same for other DEs.

BTW: www/nginx-ultimate-bad-bot-blocker; Just adding "-" won't solve the problem. The problem: Unchecked strings instead of parsing dependencies.

What exactly is the problem to be solved by pkg(7) if I may ask?
Unless I misunderstand your intentions you can either install a metaport like jmos mentioned, then remote the port and run pkg autoremove and you're done. If you need more granular control about the installed packages which prevents you from using the metaport a certain level of knowledge is implicitly attached to that (otherwise you will most likely not encounter that situation) and then you'd also know that your proposed solution has the aforementioned problem.
Other than that, you can always create your own metaport package and just remove that.

On top of that: What exactly is the usecase for "completely removing whole desktop environments" anyway? That's not a re-occurring task, right?
If you just want to test a new DE and get rid of it afterwards you can create a filesystem snapshot, install the new package, tinker around, then roll back. Alternatively create a clone from the snapshot or any of the other possible solutions (or just a speparate jail / VM which can be removed easily).

… package grouping. …

FreshPorts is our friend.

For kde5 (not to be confused with the desktop environment) we have <https://www.freshports.org/x11/kde5/#dependencies>:
  • a group of eleven runtime dependencies
  • one of which is the FreeBSD meta port for KDE Plasma – Plasma is a desktop.

When someone installs kde5 on FreeBSD, they'll get that group of eleven; plus whatever is required by each of the eleven.

plasma5-plasma, the meta port, naturally has larger groups of dependencies: <https://www.freshports.org/x11/plasma5-plasma/#dependencies>.

Above, I reworded things slightly, to more accurately include the phrase meta port.



What's below is slightly mind-bending.

x11/plasma5-plasma is:
  • the meta port for KDE Plasma.
KDE Plasma is:
  • a desktop.
x11/plasma5-plasma-desktop is:
I wondered which one of those two ports is definitely Plasma (the desktop).

I guess:
  • both are KDE Plasma
  • the meta port is intended for use cases that require KDE Plasma alone
x11/plasma5-plasma-workspace, which provides essentials such as /usr/local/bin/plasmashell, is a requirement of both plasma5-plasma and plasma5-plasma-desktop; and so on.



If you use Plasma but don't yet know the significance of plasmashell, you can safely:
  1. krunner
  2. pkill plasmashell & plasmashell

… the whole thing is quite confusing.

Configuration options might help to distinguish between the meta port and plasma5-plasma-desktop. Respectively:

Code:
===> The following configuration options are available for plasma5-plasma-5.23.2:
     PHONON=on: Include phonon-gstreamer, for sound output
     PULSEAUDIO=on: PulseAudio sound server support
===> Use 'make config' to modify these settings
Code:
===> The following configuration options are available for plasma5-plasma-desktop-5.23.5:
====> Input Method Support
     IBUS=off: Enable IBUS backend for input dialog
     SCIM=off: Enable SCIM backend for input dialog
===> Use 'make config' to modify these settings
  • this port might be preferred by someone who doesn't need the GStreamer backend for Phonon, or its plugins.

pkg remove 'mate-*'

I could do, but then any one of the three deleted packages that I want to reinstall – none of which has the phrase mate in its name – leads to reinstallation of things such as x11/mate-desktop, and so on, so I prefer to simply keep x11/mate without the rigmarole below.

Code:

Oh, it's not a bad thing to have people experiment and share ideas. Everybody learns. Discussion here revealed what might be a bug in the port of MATE, and so on.

If you like, maybe edit the title:

[TUT] How to remove whole desktop enviroments with single command

– as things turned out, it's more like discussion of:

Desktop environment packaging and removal

(Not exactly a tutorial.)

Thanks

If you think that this is unsafe or non-convenient way to managing things, remove this post.
No need to remove this post - we just do it right ;) The correct way to install and remove a desktop environment with one command:

Install
A desktop environment normally has a so called "meta port"; Such a port doesn't contain software, but dependencies to the needed packages. F.e. a pkg install mate will install all packages for the MATE desktop.

Remove
Just deinstall the the meta port, and afterwards its dependencies. In one go for the MATE desktop example:
pkg delete mate && pkg autoremove

You will be asked if it's okay to remove a bunch of packages - read it before saying "yes" (because sometimes it includes a packages that you want to keep). A pkg autoremove will only give you a good result if you took care about what's manually, and what's automatically installed. Installing the meta port instead of single packages ensures this.

… packages for the MATE desktop. …

A question for users of MATE. Do you think of the indicator applet as part of MATE?

Its description (with added emphasis):

The indicator applet exposes Ayatana Indicators in the MATE Panel. Ayatana Indicators are an initiative by Canonical to provide crisp and clean system and application status indication. They take the form of an icon and associated menu, displayed (usually) in the desktop panel. Existing indicators include the Message Menu, Battery Menu and Sound menu.
