So here is what has been keeping me up at night: At some point I
realized that nix actually made a somewhat passable language for CGI
programming:
* That `builtins.getEnv` exists as one of the impurities of Nix is
perfect as environment variables are the main way of communication
from the web server to the CGI application.
* We can actually read from the filesystem via builtins.readDir and
builtins.readFile with bearable overhead if we avoid importing the
used paths into the nix store.
* Templating and routing are convenient to implement via indented strings
and attribute sets respectively.
Of course there are obvious limitation:
* The overhead of derivations is probably much to great for them to be
useful via IfD.
* Even without derivations, nix evaluation is very slow to the point
were a trivial application takes between 100ms and 400ms to produce a
response.
* We can't really cause effects other than producing a response which
makes it not viable for a lot of applications. There are some ways
around this:
* With a custom interpreter we could have streaming and multiplexed
I/O (using lazy lists emulated via attrsets) to cause such effects,
but it would probably perform terribly.
* We can use builtins.fetchurl to call other HTTP-based microservices,
but only in very limited constraints, i. e. only GET, no headers,
and only if the tarball ttl is set to 0 in the global nix.conf.
* Terrible error handling capabilities because builtins.tryEval actually
doesn't catch a lot of errors.
To prove that it actually works, there are some demo applications,
which I invite you to run and potentially break horribly:
nix-build -A web.bubblegum.examples && ./result
# navigate to http://localhost:9000
The setup uses thttpd and executes the nix CGI scripts using
users.sterni.nint which automatically passed `depot`, so they can
import the cgi library.

nint (short for nix interpreter) is a tiny wrapper around nix-instantiate
which allows to run nix scripts, i. e. nix expressions that conform to
a certain calling convention. A nix script runnable using nint must
conform to the following constraints:
* It must evaluate to a function which has a set pattern with an
ellipsis as the single argument.
* It must produce a string as a return value or fail.
When invoked, a the expression receives the following arguments:
* `currentDir`: the current working directory as a nix path
* `argv`: a list of strings containing `argv` including `argv[0]`
* extra arguments which are manually specified which allows for
passing along dependencies or libraries, for example:
nint --arg depot '(import /depot {})' my-prog.nix [ argv[1] … ]
would pass along depot to be used in `my-prog.nix`.
Such nix scripts are purely functional in a sense: The way inputs can be
taken is very limited and causing effects is also only possible in a
very limited sense (using builtins.fetchurl if TARBALL_TTL is 0,
adding files and directories to the nix store, realising derivations).
As an approximation, a program executed using nint can be thought of
as a function with the following signature:
λ :: environment → working directory → argv → stdout
where environment includes:
* the time at the start of the program (`builtins.currentTime`)
* other information about the machine (`builtins.currentSystem` …)
* environment variables (`builtins.getEnv`)
* the file system (`builtins.readDir`, `builtins.readFile`, …) which
is the biggest input impurity as it may change during evaluation
Additionally import from derivation and builtin fetchers are available
which introduce further impurities to be utilized.
Future work:
* Streaming I/O via lazy lists. This would allow usage of
stdin and output before the program terminates. However this would
require using libexpr directly or writing a custom nix interpreter.
A description of how this would work can be found on the website of the
esoteric programming language Lazy K: https://tromp.github.io/cl/lazy-k.html
* An effect system beyond stdin / stdout.
* Better error handling, support setting exit codes etc.
These features would require either using an alternative or custom
interpreter for nix (tvix or hnix) or to link against libexpr directly
to have more control over evaluation.

We use builtins.split directly as it should be a bit more efficient as
lib.splitStrings. Also its returning of a list for every regex match is
useful to update the state while parsing the tokens:
* The tokens are obtained by splitting the string at every '%'
* Everytime we see a boundary (that is a list in the returned
list of builtins.split), we know that the first two chars of
the next string are a percent encoded character.
One implementation flaw is that it will currently crash if it encounters
mal-formed URLs (since int.fromHex chrashes if it encounters any non
hex digit characters) and accepts some malformed urlencoding like
"foo %A".

In order to arbitrarily split netencode over multiple reads, we need
to make the parser completely streaming, so that it recognizes all
cases where it needs more input.
Luckily, this is fairly trivial, after working around a bunch of
overeager parsing.
The tricky part was the giant `alt`, where inner parsers would start
consuming input and thus become incomplete when they fail afterwards.
Sinc the format *always* starts the different types with one
discriminator char, we can use that to instantly return the parser and
try the next one instead.
The other tricky part was that lists and records would parse all inner
elements and then choke on the empty string after the last element,
because the inner parser would consume at least the descriminator, and
an empty string is always `Incomplete`. We wrap these into a small
combinator which plays nice with `many0` in that regard.

Very simple builder which builds (optionally) gzipped man pages from a
list of attrsets and links them into a common man directory with the
correct layout, so it should be installable immediately.
Additionally runs mandoc -T lint, but by default only for informational
purposes as it is very strict and some things are almost never true (for
example all Xrs being present in the respective directory).
buildManPages.single exposes the internal builder for a single,
optionally gzipped man page from a nix attrset.

the codegen level because LLVM (unsurprisingly) only allows Void types
