Nix unfortunately has terrible escaping syntax: If something is an
escape sequence it does not know, like \0, it just swallows the
backslash and returns the second character (byte) as is (yes,
"\0" == "0" is true). This created the following bug in nixFileName
which should have resulted in at least a parse error: "(.*)\.nix" is
the same as "(.*).nix" which meant that nixFileName matched anything
that is at least 4 characters long and ends in "nix". This lead to
readTree creating double attributes when directories are involved or
attributes for non-nix files.

By using an extremely trivial derivation we can ensure that it will not
throw if evaluated using deepSeq. When using stdenv.mkDerivation or
similar at some point something will most likely throw or generate some
kind of error which is alright in the context of nixpkgs, but makes
testing yants harder than you'd think it should be.

Refactor assertEq and assertThrows to be implemented in terms of a more
generic assertBool to reduce code duplication and ease adding new assert
types.
To preserve meaningful error messages AssertResult is changed slightly:
nope-eq and nope-throw have been replaced by a single nope branch which
contains an AssertErrorContext which contains error information. To
implement an assert assertBoolContext (which is not exposed) can be
used: It takes an AssertErrorContext which is returned in case of an
error and a boolean determining whether the assert was successful.
The currently possible AssertErrorContext are:
* should-throw: error result of assertThrows, formerly nope-throw
* not-equal: error result of assertEq, formerly nope-eq

Introduces the concept of a “tag”, a single-keyed attrset which
annotates a nix value with a name.
This can be used to implement tagged unions (by implying the list of
possible tags is well-known), which has some overlap with how
`nix.yants` does it.
However, the more fascinating use-case is in concert with a
so-called discriminator, `match` and hylomorphisms.
The discriminator can take a nix value, and add tags to it based on
some predicate.
With `match`, we can then use that information to convert the
discriminated values again.
With `hylo`, we can combine both the “constructive” discriminator step
with the “destructive” match step to recursively walk over a nix data
structure (based on a description of how to recurse, e.g. through attrset
values or list values), and then apply a transformation in one go.

The subtree continues the history of the old git repository.
Setting the GOROOT_FINAL environment variables replaces the absolute
location of the Go standard library sources in the final build
artefacts with a fake location (in this case starting with
go/src/...).
This is despite the documentation for 'trimpath' (in 'go tool

true for user code!
I figured this out by reading through the implementation of the other

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.
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.
Adds a Nix function to build a Lisp library out of a specified set of
Nix files. All files are combined into a single FASL.
This is by design only compatible with SBCL (for now).
This moves the various projects from "type-based" folders (such as
"services" or "tools") into more appropriate semantic folders (such as
"nix", "ops" or "web").
Deprecated projects (nixcon-demo & gotest) which only existed for
testing/demonstration purposes have been removed.
