The nixpkgs-unstable channel's programs.sqlite was used to identify
packages producing exactly one binary, and these automatically added
to their package definitions wherever possible.
The xdg-open utility is only ever a runtime dependency and its
dependents only expect that it accept a URI as a command line
argument and do something with it that the user would expect.
For such as a trivial relationship it should be possible for
users to override xdg-open with something else in their PATH.
According to https://repology.org/repository/nix_unstable/problems, we have a
lot of packages that have http links that redirect to https as their homepage.
This commit updates all these packages to use the https links as their
homepage.
The following script was used to make these updates:
```
curl https://repology.org/api/v1/repository/nix_unstable/problems \
| jq '.[] | .problem' -r \
| rg 'Homepage link "(.+)" is a permanent redirect to "(.+)" and should be updated' --replace 's@$1@$2@' \
| sort | uniq > script.sed
find -name '*.nix' | xargs -P4 -- sed -f script.sed -i
```
When opening `shutter` it adds an indicator icon to the status bar.
However this doesn't happen (and an ugly default icon will be used) if
`shutter` can't find the `hicolor-icon-theme`. In such a case a warning
like this can be found in `stderr`:
```
Gtk-WARNING **: Could not find the icon 'image-png'. The 'hicolor' theme
was not found either, perhaps you need to install it.
```
As I don't think that we should force users to install this theme
globally and several other packages including `tor-browser`, `gparted`
or `clawsmail` add `hicolor-icon-theme` to their closure this seems to
be a fair measure.
However, none of the exporters I tried actually _worked_, but now
shutter at least returns an error to the user (pop-up UI element)
instead of silently hanging and only leaving messages on stdout/stderr
about the missing deps.
AFAICS, this changes the failure of Screenshot->Export functionality
from a packaging bug to an application bug (upstream).
Fixes this:
$ shutter
ERROR: imagemagick is missing --> aborting!
Due to 73f1f5eb39
("imagemagick: split dev output to fix#9604") which was committed in
the same period as shutter was added to nixpkgs.
Screenshot and annotation tool.
The application may complain about missing GConf dbus service[1], but it
still works (and remembers its settings, AFAICT).
[1]: The error message is (line wrapped):
GConf Error: Failed to contact configuration server; the most
common cause is a missing or misconfigured D-Bus session bus daemon. See
http://projects.gnome.org/gconf/ for information. (Details - 1: GetIOR
failed: GDBus.Error:org.freedesktop.DBus.Error.ServiceUnknown: The name
org.gnome.GConf was not provided by any .service files)
