Among other things, this will allow *2nix tools to output plain data
while still being composable with the traditional
callPackage/.override interfaces.
This allows one to specify "related packages" in NixOS that get rendered into
the configuration.nix(5) man page. The interface philosophy is pretty much
stolen from TeX bibliography.
Previously only the line numbers of a giant, internally generated XML file were
printed, without any kind of debuggability.
Now at least the mentioned lines are printed with a little bit of surrounding
context (to have something to grep for).

In light of Emacs packaging improvements such as those mentioned
in #11503, and with the addition of a systemd service (#15807
and #16356), and considering that the wiki page is completely
out of date (#13217), it seems that some documentation is in order.
* Hydra doesn't like spaces in filenames.
* The zip file contained nix/store/.../OEBPS rather than OEBPS at
top-level, causing some programs (like okular) to barf.
* Remove the redundant $dst/epub directory.
This allows to use <olink> tags inside NixOS options to reference
sections from the manual. I've originally introduced it in #14476 to
reference the Taskserver specific documentation from the options
reference but as suggested by @nbp, this was done as a separate pull
request to ensure greater visibility rather than being "hidden" in the
Taskserver branch.
The build time for the manual is around 30s on my machine without this
change and 34s with this change, so it shouldn't have a very big impact
on the build time of the manual.
Olinks between the options reference and the manual now will look like
this:
"More instructions about NixOS in conjuction with Taskserver can be
found in the NixOS manual at Chapter 15, Taskserver."
More documentation about olinks can be found here:

This adds a Taskserver module along with documentation and a small
helper tool which eases managing a custom CA along with Taskserver
organisations, users and groups.
Taskserver is the server component of Taskwarrior, a TODO list
application for the command line.
The work has been started by @matthiasbeyer back in mid 2015 and I have
continued to work on it recently, so this merge contains commits from
both of us.
Thanks particularly to @nbp and @matthiasbeyer for reviewing and
suggesting improvements.
I've tested this with the new test (nixos/tests/taskserver.nix) this
branch adds and it fails because of the changes introduced by the
closure-size branch, so we need to do additional work on base of this.
This reverts commit 1d77dcaed3.
It will be reintroduced along with #14700 as a separate branch, as
suggested by @nbp.
I added this to this branch because I thought it was a necessary
dependency, but it turns out that the build of the manual/manpages still
succeeds and merely prints a warning like this:
warning: failed to load external entity "olinkdb.xml"
Olink error: could not open target database 'olinkdb.xml'.
Error: unresolved olink: targetdoc/targetptr = 'manual/module-taskserver'.
The olink itself will be replaced by "???", so users looking at the
description of the option in question will still see the reference to
the NixOS manual, like this:
More instructions about NixOS in conjuction with Taskserver can be found
in the NixOS manual at ???.

My first attempt to do this was to just use a conditional <refsection/>
in order to not create exact references in the manpage but create the
reference in the HTML manual, as suggested by @edolstra on IRC.
Later I went on to use <olink/> to reference sections of the manual, but
in order to do that, we need to overhaul how we generate the manual and
manpages.
So, that's where we are now:
There is a new derivation called "manual-olinkdb", which is the olinkdb
for the HTML manual, which in turn creates the olinkdb.xml file and the
manual.db. The former contains the targetdoc references and the latter
the specific targetptr elements.
The reason why I included the olinkdb.xml verbatim is that first of all
the DTD is dependent on the Docbook XSL sources and the references
within the olinkdb.xml entities are relative to the current directory.
So using a store path for that would end up searching for the manual.db
directly in /nix/store/manual.db.
Unfortunately, the <olinks/> that end up in the output file are
relative, so for example if you're clicking on one of these within the
PDF, the URL is searched in the current directory.
However, the sections from the olink's text are still valid, so we could
use an alternative URL for that in the future.
The manual doesn't contain any links, so even referencing the relative
URL shouldn't do any harm.

It's not by any means exhaustive, but we're still going to change the
implementation, so let's just use this as a starting point.
Signed-off-by: aszlig <aszlig@redmoonstudios.org>
- Enforce that an option declaration has a "defaultText" if and only if the
type of the option derives from "package", "packageSet" or "nixpkgsConfig"
and if a "default" attribute is defined.
- Enforce that the value of the "example" attribute is wrapped with "literalExample"
if the type of the option derives from "package", "packageSet" or "nixpkgsConfig".
- Warn if a "defaultText" is defined in an option declaration if the type of
the option does not derive from "package", "packageSet" or "nixpkgsConfig".
- Warn if no "type" is defined in an option declaration.
First of all this fixes an evaluation error I introduced in ae466ba,
which wasn't triggered by any of my own tests against the change because
there are usually no NixOS options that are declared outside of the
<nixpkgs> tree. I renamed the attribute name from "fn" to "fileName"
first and later to "fullPath" but forgot one still occuring "filename".
Thanks to @vcunat for noticing this.
Another thing that he pointed out was that the "stripPrefix" function
can be factored away entirely, because it's very similar to
"removePrefix" in <nixpkgs/lib>.
Unfortunately we can't use "removePrefix" as is, because we need to
account for the final shlash.
So instead of removing it twice and/or retaining "stripPrefix", let's
append a shlash on every "prefixesToStrip" and we can use "removePrefix"
as is.
Tested with:
taalo-build nixos/release.nix -A tests.installer.simple.x86_64-linux
And:
w3m -dump "$(
nix-build nixos/release.nix -A manual.x86_64-linux

Let's use a simple (unflipped) fold and break out the actual core
stripPrefix function from stripAnyPrefixes (I personally love
point-less^H^H^H^Hfree style but if I'd be anal I'd even go further and
factor away the "fn:").
Also, let's use path as a better name for "fn" (filename), because
that's what it is and also cannot be confused with "fn" meaning
"function".
We now toString all of the prefixes, so there shouldn't be any need to
implicily toString the extraSources anymore.

Regression introduced by e6cd147ae7.
This broke all of the installer tests, because they needed to rebuild
the manual within the test machine, while it only has a closure of the
already pre-built system in place.
The problem here was just that the order of the arguments got mixed up
in stripAnyPrefixes, so it was actually trying to strip the path off the
prefix, not the other way around.
So in the end no prefix was stripped at all, so we ended up having full
store paths in the manual, which in turn caused the build within the VM
to fail, because the prefixes differed.
