The upstream session files display managers use have no concept of sessions being composed from
desktop manager and window manager. To be able to set upstream session files as default
session, we need a single option. Having two different ways to set default session would be confusing,
though, so we decided to deprecate the old method.
We also created separate script for each session, just like we already had a separate desktop
file for each one, and started using displayManager.sessionPackages mechanism to make the
session handling more uniform.
There's two ways of providing graphical sessions now:
- `displayManager.session` via. `desktopManager.session` and
`windowManager.session`
- `displayManager.sessionPackages`
`sessionPackages` doesn't make a distinction between desktop and window
managers. This makes selecting a session provided by a package using
`desktopManager.default` nonsensical.
We therefor introduce `displayManager.defaultSession` which can select a session
from either `displayManager.session` or `displayManager.sessionPackages`.
It will default to `desktopManager.default + windowManager.default` as before.
If the dm default is "none" it will select the first provided session from
`sessionPackages`.
Currently, exa fails when being executed in a git repository with
symlinks pointing to a non-existing location.
This can happen quite often with garbage-collected result links, or in
bazel repositories.
A fix was PR'ed in September at https://github.com/ogham/exa/pull/584,
but upstream seems to be not responding.
Let's apply this patch until there's a release containing the fixes.
Also move the build-time dependencies to nativeBuildInputs, and drop perl as it no longer seems to be necessary (CMake is not looking for it any more).
They are not compatible with Python 3, upstream as dead, and nothing uses the bindings any more.
This is a progress in getting rid of Python 2 from closures of most people (samba, which depends on gamin shared library is common dependency).
* format with nixpkgs-fmt
* drop unneeded dependencies
* gnome-doc-utils → yelp-tools since 3.6.0
* intltool → gettext since 3.16.2
* move build-time deps to nativeBuildInputs
* add metadata
