The current FlightGear expression doesn't work:
bash$ nix-build -A flightgear
/nix/store/3c47sibzb9h1vhnn0gnh692hkpjc5p5v-flightgear-2.10.0
bash$ ./result/bin/fgfs
ERROR: The path '/nix/store/3c47sibzb9h1vhnn0gnh692hkpjc5p5v-flightgear-2.10.0/lib/FlightGear' does not exist in the file system.
Base package check failed:
Version [none] found at: /nix/store/3c47sibzb9h1vhnn0gnh692hkpjc5p5v-flightgear-2.10.0/lib/FlightGear
Version 2.10.0 is required.
Please upgrade/downgrade base package and set the path to your fgdata
with --fg-root=path_to_your_fgdata
We could probably make the 2.10.0 version run, but I had already
upgraded it to 2.12.0 before I made it work. It seems only the data dir
configuration was wrong/missing: FG_DATA_DIR="$out/share/FlightGear/".
Simgear must be in version sync with flightgear, hence the upgrade.
Most of the diff is because I rewrote the flightgear expression to what
I think is the "new style". I wanted to add a preConfigure phase but
didn't understand why this expression had custom phases. So I just
rewrote the whole thing to something I consider more readable.
The current asciidoc expression is impure; it relies on several tools to
be found in PATH at runtime. This commit adds a enableStandardFeatures
parameter that, if true, pulls in all dependencies and patches asciidoc
to contain full paths to the tools.
I've set enableStandardFeatures = false for the existing asciidoc
attribute so that the closure size stays unchanged, at 255 MiB. The new
asciidocFull attribute (with enableStandardFeatures = true) has a
closure size of 1.5 GiB.
imagemagick, transfig, inkscape, fontconfig and ghostscript are missing
dependencies of dblatex. Instead of adding all those dependencies to the
existing dblatex attribute, make a new dblatexFull attribute for that.
Also pass --use-python-path at install time so that script shebangs end
up with #!/path/to/python instead of #!/path/to/env python (which is
impure when not run in a wrapper).
* Remove package name
* Start with upper case letter
* Remove trailing period
Also reword some descriptions and move some long descriptions to
longDescription.
I'm not touching generated packages.
