This commit makes Meson the default buildsystem for Lix.
The Make buildsystem is now deprecated and will be removed soon, but has
not yet, which will be done in a later commit when all seems good. The
mesonBuild jobs have been removed, and have not been replaced with
equivalent jobs to ensure the Make buildsystem still works.
The full, new commands in a development shell are:
$ meson setup ./build "--prefix=$out" $mesonFlags
(A simple `meson setup ./build` will also build, but will do a different
thing, not having the settings from package.nix applied.)
$ meson compile -C build
$ meson test -C build --suite=check
$ meson install -C build
$ meson test -C build --suite=installcheck
(Check and installcheck may both be done after install, allowing you to
omit the --suite argument entirely, but this is the order package.nix
runs them in.)
If tests fail and Meson helpfully has no output for why, use the
`--print-error-logs` option to `meson test`. Why this is not the default
I cannot explain.
If you change a setting in the buildsystem, most cases will automatically
regenerate the Meson configuration, but some cases, like trying to build
a specific target whose name is new to the buildsystem (e.g.
`meson compile -C build src/libmelt/libmelt.dylib`, when
`libmelt.dylib` did not exist as a target the last time the buildsystem
was generated), then you can reconfigure using new settings but existing
options, and only recompiling stuff affected by the changes:
$ meson setup --reconfigure build
Note that changes to the default values in `meson.options` or in the
`default_options :` argument to project() are NOT propagated with
`--reconfigure`.
If you want a totally clean build, you can use:
$ meson setup --wipe build
That will work regardless of if `./build` exists or not.
Specific, named targets may be addressed in `meson build -C build <target>`
with "target ID" if there is one, which is the first string argument
passed to target functions that have one, and unrelated to the variable
name, e.g.:
libexpr_dylib = library('nixexpr', …)
can be addressed with:
$ meson compile -C build nixexpr
All targets may be addressed as their output, relative to the build
directory, e.g.:
$ meson compile -C build src/libexpr/libnixexpr.so
But Meson does not consider intermediate files like object files
targets. To build a specific object file, use Ninja directly and
specify the output file relative to the build directory:
$ ninja -C build src/libexpr/libnixexpr.so.p/nixexpr.cc.o
To inspect the canonical source of truth on what the state of the
buildsystem configuration is, use:
$ meson introspect
Have fun!

The statically embedded busybox is not required for Lix to work, but
package.nix explicitly sets this, which was accidentally being ignored.

This commit adds the capability for building the Doxygen internal API
docs in the Meson buildsystem, and also makes doing so the default for
the internal-api-docs hydra job. Aside from the /nix-support directory,
which differed only by the hash part of a store path, the outputs of
hydraJobs.internal-api-docs before and after this commit were
bit-for-bit identical on my machine.

Either the contents of `line` could cause format errors, or this usage
is Technically safe. However, I trust nothing, especially with
boost::format.

Previously if isStorePath() was called on anything other than a
top-level /nix/store/some-path, it would throw a BadStorePath exception.
This commit duplicates the absolutely trivial check, into
maybeParseStorePath(), and leaves exception throwing to
parseStorePath(), the function that assumes you're already giving a
valid path instead of the one whose purpose is to check if its valid or
not...

Saves us a bunch of thinking about how to handle symlinks, and prevents
the DNS config from changing on the fly under the build, which may or may
not be a good thing?

93cc06334 removed nss-cacert from the binary tarball, but they're
necessary for global compatibility (and for our installer). This is what
results in cacerts being in the default profile, so e.g. the daemon has
TLS certs without having to use the system ones.
There's a fallback behavior in the daemon script in case these wind up
missing from the profile, but we don't want to have to rely on that,
since the fallback fails if it doesn't recognize one of a handful of
distros.

* changes:
meson: fix log-dir
manual: build docs with dummy envs
libcmd: install generated headers as well
docs: redo content generation for mdbook and manual
this was previously used because the macOS docs build would otherwise
pull files out of the host nix store. or something. not sure about it
Change-Id: I76b51eac1ebc5de5f00e2e4be086dd8db3eeb8e6
manpages can be rendered using the markdown output of mdbook, the rest
of the manual can generated out of the main doc/manual source tree. we
still use lowdown to actually render manpages instead of eg mdbook-man
because lowdown does generate reasonably good manpages (though that is
also somewhat debatable, but they're a lot better than mdbook-man).
doing this not only lets us drastically simplify the lowdown pipeline,
but also remove all custom {{#include}} handling since now mdbook does
all of it, even for the manpage builds. even the lowdown wrapper isn't
entirely necessary because lowdown can take all wrapper arguments with
command line flags rather than bits of input file content.
This also implements running mdbook in Meson, in order to generate the
manpages. The mdbook outputs are also installed in the usual location.

this should be a link, not an anchor. it should also point to the
`gloss-store` element, not the `#gloss-store` element.

Previously, errors while printing values in `nix repl` would be printed
in `«error: ...»` brackets rather than displayed normally:
```
nix-repl> legacyPackages.aarch64-darwin.pythonPackages.APScheduler
«error: Package ‘python-2.7.18.7’ in /nix/store/6s0m1qc31zw3l3kq0q4wd5cp3lqpkq0q-source/pkgs/development/interpreters/python/cpython/2.7/default.nix:335 is marked as insecure, refusing to evaluate.»
```
Now, errors will be displayed normally if they're emitted at the
top-level of an expression:
```
nix-repl> legacyPackages.aarch64-darwin.pythonPackages.APScheduler

```
Errors emitted in nested structures (like e.g. when printing `nixpkgs`)
will still be printed in brackets.

The configured sysconfdir is used to look for nix.conf, so it needs
to be /etc, and not $out/etc, so we separate out the place where shell
profile files are installed, which is the only other place sysconfdir is
at all used.
See lix-project/lix#231 (comment)
for more info.
Change-Id: Idbed8ba82e711b8a9d6b6127904befa27d58e279
Instead of $sysconfdir.
Fixes#231, but there's more to do in following commits to make
Meson-built Lix actually look in /etc/nix.

These scripts were originally written by horrors, and have since been
hacked up a lot by jade. We are putting them up as a CL since it is
better to have checked in benchmarking scripts than to not have
benchmarking scripts.

this isn't strictly necessary, but it'll make it a lot easier to put the
generated files used by the autoconf build system in this directory too.
doing this now already will make the meson transition a lot easier later
Change-Id: I5fb39eade2ff88b6093c9ee436c9e8db793e9448
this would make meson build compatibility unnecessarily hard and
the cli does not change often enough to justify this complexity.

not sure why this was done the way it was considering that includes are
a feature the doc toolchain had previously. let's just always have some
kind of entry for the upcoming release in the dev manual builds even if
that means having a completely empty release notes chapter.
the release notes generation script isn't entirely functional right now
due to pre-commit hooks, but it's good enough for time being. we need a
better release process for notes anyway.

mdbook already does include processing of its own, and the custom
processing code has always admitted as much. we don't need it for
the mdbook build at this point if we run our preprocessors in the
right order, and maybe we can even have mdbook to return complete
pages to us that we only have to pass to lowdown without any more
preprocessing of our own.

for some reason these three were anchors, not links, but had they been
links they wouldn't've worked because they're not defined anywhere but
here. in the print version of the manual they're duplicated many times
over (creating id collisions), so we should better remove them anyway.

Adds a `repl-overlays` option, which specifies files that can overlay
and modify the top-level bindings in `nix repl`. For example, with the
following contents in `~/.config/nix/repl.nix`:
info: final: prev: let
optionalAttrs = predicate: attrs:
if predicate
then attrs
else {};
in
optionalAttrs (prev ? legacyPackages && prev.legacyPackages ? ${info.currentSystem})
{
pkgs = prev.legacyPackages.${info.currentSystem};
}
We can run `nix repl` and use `pkgs` to refer to `legacyPackages.${currentSystem}`:
$ nix repl --repl-overlays ~/.config/nix/repl.nix nixpkgs
Lix 2.90.0
Type :? for help.
