Adds a function that can launch Sly with a pre-configured SBCL for a
Lisp derivation in the depot.
This makes it convenient to spin up development environments for Lisp
libraries and programs by simply calling `M-x nix/sly-from-depot RET
tools.something`.
This relies on `nix-depot-path` being configured currently as I have
not yet reliably added the depot to my NIX_PATH on all machines.
Adds the necessary attributes on derivations created by
buildLisp.program for them to be passed to buildLisp.sbclWith.
This makes it possible to easily spin up Lisp environments that
contain everything needed for a given program.
Sets up Lisp modes in Sly REPL and points at the local hyperspec
checkout.
In fact the Hyperspec bit should probably be managed by Nix, but one
step at a time.
This is pretty much exactly the derivation from nixpkgs, with some
things removed to reduce the closure size (e.g. the various formatters
used in the default cgit version, which are replaced by cheddar in my
setup).
This overrides the upstream derivation to:
* use local sources
* build `git send-email`
It also calls autoreconf before building because files that are
included in the git distribution tarball (which the normal derivation
uses) are missing from source.
If you're on tree/foo/bar, the about link will now point to
about/foo/bar.
Currently the annoying thing about this is that it will also do it for
files.
This means that individual subtrees of a repository will also have
their READMEs rendered on the about page, for example:
/foo/bar/README.md
Will render on:
/about/foo/bar/
This is useful for monorepo setups in which subtrees represent
individual projects.
Generates URLs that do not include the repository name.
On git.tazj.in, only one repository (depot) is served - hence URLs
generated by cgit need not include the name.
Adds dottime (as defined on https://dotti.me) as a timestamp format.
This format is designed to simplify working with timestamps across
many different timezones by keeping the timestamp format itself in
UTC (and indicating this with a dot character), but appending the
local offset.
This is implemented as a new format because the timestamp needs to be
rendered both as UTC and including the offset, an implementation using
a strftime formatting string is not sufficient.
I can not currently find a way to set the CFFI variables correctly to
get it to load libraries from Nix.
In the absence of that feature, a wrapper also does the trick.
It's not enough to compile in the right order - turns out you also
have to load the compiled objects in the right order.
To achieve this some cursed code has been added that changes the Lisp
generated by Nix to compile the other Lisp so that it also generates
some bash, which Nix can then use to concatenate the FASLs in the
right order to feed them to Lisp again.
It works but I'll replace it with a more elegant solution once one is
needed.
Similar to buildGo.nix, the library derivations carry information
about their dependencies which is merged when a load file is
instantiated.
The load files are created when compiling libraries, but will in the
future also be created when wrapping SBCL and dumping images.
