Move `doomdirs/example/` to just `doomdir/`, and rename the package
using it from `doom-example` to `doom-emacs`.
I do not expect to need multiple doomdirs checked in again, and I can
unclutter the packages provided by the flake a bit now that most of them
are checks.
Detect module flags by walking package.el files.
This still does not build all dependencies, because some are enabled
only if some flag or other module is disabled. But this should be close.
...not yet with all flags, but that's the next step.
This surfaced several problems not caught by the existing "full" build,
because that did not enable dependencies conditionally enabled if a
second module is enabled.
There are a small number of dependencies only enabled if a second module
is *not* enabled, which I intend to add some manual tests for.
They do not have src set, so if we pull them in without having a pin
they fail to build.
Noticed with org, so add a test for that. Probably not the only one
affected, though.
Fixes#4
This seems to be much more space-efficient: ~/.cache/nix/tarball-cache
is about 700MiB uncompressed, under 300MiB as tzst (using tar's
defaults, CI uses zstdmt but I assume will be in the same ballpark). The
gitv3 cache is multiple GiB.
CI will still build doom-example using fetchGit. I intend to shrink the
number of modules enabled in the example to keep gitv3 cache size under
control.
