This plugin adds support for the GT-S650, Perfection V19 and
Perfection V39 scanners. I've tested it personally with an Epson
Perfection V39.
This plugin uses the ISCAN_FIRMWARE_DIR environment variable, not
ISCAN_FW_DIR. A quick grep didn't find any use of ISCAN_FW_DIR in the
currently packaged plugins, but a quick Google suggests that this
variable does (or at least used to) exist, so I'm not touching it.
Building with -std=c99 breaks the obsolete "%as" format string, which
completely breaks the parsing of epkowa interpreters. This means that
no scanner requiring plugins worked.
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@$2@' \
| sort | uniq > script.sed
find -name '*.nix' | xargs -P4 -- sed -f script.sed -i
```
I haven't been doing any maintenance for a long time now and not only
do I get notified, it also creates a fake impression that all these
packages had at least one maintainer when in practice they had none.
+ added webarchive source for reliable builds in the future
+ removed `${version}` from url, as it actually adds more hassle to
have it in there and no benefits whatsoever, since the url keeps
changing other parts too
+ building from gitlab source
+ reorderd dependencies to be in logical/alphabetical order
+ replaced patches with substituteInPlace, as patches broke the installChecks
and substituteInPlace may be more robust than making new patches for each
release. Also the compiled source is now closer to upstream than
before.
+ added installChecks
+ added all supported devices as listed on epson.net
