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
* freetype: Remove unnecessary `--disable-static`.
The true-by-default `dontDisableStatic` already takes care of it.
Fixes freetype not being overridable to have static libs.

Beginning with commit 8ffd6af27e,
the build recipe for `hplipWithPlugin` explicitely drops a
udev rule file that is delivered with the sources.
In `hplip` (without plugin), the rule file is retained.
The udev rules takes care of uploading firmware
to certain printers (and maybe of other things),
e.g. to HP LaserJet 1000.
This commit reinstates the rule file and
expands the fixup script so that the rules
are also patched in the WithPlugin version.
hplip's udev rule uses `nohup` to attempt to detach
its printer configuration script from the udev process.
However, this attempt is futile as udev
tracks its child processes with cgroups:
https://unix.stackexchange.com/a/243648
The hardcoded path to `nohup` was patched to use Nix' `nohup`.
This commit alters the patch script so
that it simply drops the call to `nohup`.
This round is without the systemd CVE,
as we don't have binaries for that yet.
BTW, I just ignore darwin binaries these days,
as I'd have to wait for weeks for them.
xboxdrv doesn’t use scons for installing, but instead using a
makefile! Everything else is in scons so we have to keep that. I’ve
added a dontUseSconsInstall flag to the scons setup-hook to skip the
automatic overwrite of default “make install” call.
In a few cases it wasn't clear so I left them as-is.
While visiting these moved other things to nativeBuildInputs
when it was clear they were one of these cases:
* makeWrapper
* archive utilities (in order to unpack src)
* a few of these might no longer be needed but leaving for another day
This makes the command ‘nix-env -qa -f. --arg config '{skipAliases =
true;}'’ work in Nixpkgs.
Misc...
- qtikz: use libsForQt5.callPackage
This ensures we get the right poppler.
- rewrites:
docbook5_xsl -> docbook_xsl_ns
docbook_xml_xslt -> docbook_xsl
diffpdf: fixup
* treewide: http -> https sources
This updates the source urls of all top-level packages from http to
https where possible.
* buildtorrent: fix url and tab -> spaces
Also fixes multiples issues:
- broken plugins:
- `fax_marvell.so file is not present or symbolic link is missing`
- `lj.so library file doesn't have user/group execute permission.`
- `bb_escl.so file is not present or symbolic link is missing`
- multiple error during configuration phase which prevented `*.ppd`
generation:
- `ppdc: Unable to find include file "<font.defs>"`
- patched configure time `perl` script
- patched use of `file`
- some potentially problematic filter and services:
- patched reference to ghost script and fonts dir in filter.
- patched usb configuration service.
- patch scripts so that they refer to valid location.
Add some options:
- `withStaticPPDInstall`: Install `*.ppd` files along with `*.drv`.
When true, configure outputs: `checking for cups ppd install... yes`.

They aren't meant to be critical (uncatchable) errors.
Tested with nix-env + checkMeta:
[ "x86_64-linux" "i686-linux" "x86_64-darwin" "aarch64-linux" ]
We cannot rely on wrapPythonPrograms to wrap the installed executables because
they are symlinks (which it ignores). Instead, we have to emulate it to make
the wrappers ourselves.
Additional CUPS drivers can be added via "services.printing.drivers" but
Gutenprint was an exception. It was possible to add a Gutenprint
derivation to that list and it would work at first but unlike the other
drivers Gutenprint requires a script to be run after each update or any
attempt to print something would simply fail and an error would show up
in the jobs queue (http://localhost:631/jobs/):
"The PPD version (5.2.11) is not compatible with Gutenprint 5.2.13.
Please run
`/nix/store/7762kpyhfkcgmr3q81v1bbyy0bjhym80-gutenprint-5.2.13/sbin/cups-genppdupdate'
as administrator."
This is due to state in "/var/lib/cups/ppd" and one would need to run
"/nix/store/.../bin/cups-genppdupdate -p /var/lib/cups/ppd" manually.
The alternative was to enable the following option:
"services.printing.gutenprint" but this had two disadvantages:
1) It is an exception that one could be unaware of or that could
potentially cause some confusion.
2) One couldn't use a customized Gutenprint derivation in
"services.printing.drivers" but would instead have to overwrite
"pkgs.gutenprint".
This new approach simply detects a Gutenprint derivation in
"services.printing.gutenprint" by checking if the meta set of a
derivation contains "isGutenprint = true". Therefore no special
exception for Gutenprint would be required and it could easily be
applied to other drivers if they would require such a script to be run.
* pkgs: refactor needless quoting of homepage meta attribute
A lot of packages are needlessly quoting the homepage meta attribute
(about 1400, 22%), this commit refactors all of those instances.
* pkgs: Fixing some links that were wrongfully unquoted in the previous
commit
* Fixed some instances
* hplip: introduce nettools dependency
Some HP printers (notably a HP MFP M477fnw) need to run `hostname` as part of
the printing process. This executable is provided by the "nettools" package.
* hplip: prepend nettools to PATH
Rework gutenprint derivation:
* Convert to regular stdenv.mkDerivation;
* Enable IJS driver;
* Fix cups-genppdupdate;
* Move things around to the proper directories;
* Enable parallel building;
* Clean from old hacks.
The most complex problems were from dealing with switches reverted in
the meantime (gcc5, gmp6, ncurses6).
It's likely that darwin is (still) broken nontrivially.
