[PATCH 00/12] doc: cleanup old cruft and asciidoctor revamp

[Felipe Contreras]

This patch series gets rid of old unnecessary workarounds and convoluted solutions.

Additionally it cleanups the asciidoctor-specific code so it ends up much more simpler.

This goes on top of my other cleanup patches [1].

[PATCH 01/12] doc: remove GNU troff workaround

[Felipe Contreras]

In 2007 the docbook project made the mistake of converting ' to \' for
man pages [1]. It's a problem because groff interprets \' as acute
accent which is rendered as ' in ASCII, but as ´ in utf-8.

This started a cascade of bug reports in git [2], debian [3], Arch Linux
[4], docbook itself [5], and probably many others.

A solution was to use the correct groff character: \(aq, which is always
rendered as ', but the problem is that such character doesn't work in
other troff programs.

A portable solution required the use of a conditional character that is
\(aq in groff, but ' in all others:

  .ie \n(.g .ds Aq \(aq
  .el .ds Aq '

The proper solution took time to be implemented in docbook, but in 2010
they did it [6]. So the docbook man page stylesheets were broken from
1.73 to 1.76.

Unfortunately by that point many workarounds already existed. In the
case of git GNU_ROFF was introduced, and in the case of Arch Linux
a mappig from \' to ' was added to groff's man.local. Other
distributions might have done the same, or similar workarounds.

Since 2010 there is not need for this workaround, which is fixed
elsewhere not just in docbook, but other layers as well.

Let's remove it.

Also, it's GNU troff, not GNU roff.

[PATCH 02/12] doc: use --stringparam in xmlto

[Felipe Contreras]

Commit 50d9bbba92 (Documentation: Avoid use of xmlto --stringparam,
2009-12-04) introduced manpage-base-url.xsl because ancient versions of
xmlto did not have --stringparam.

However, that was more than ten years ago, no need for that complexity
anymore.

[PATCH 03/12] doc: simplify version passing

[Felipe Contreras]

The code to pass the version of the man page comes from 2007:
7ef195ba3e (Documentation: Add version information to man pages,
2007-03-25). However, both asciidoc and asciidoctor already do this by
default.

Asciidoctor doesn't read manversion, but there's no need since both
tools just join mansource and manversion.

Let's do that ourselves and get rid of a bunch of code.

[PATCH 05/12] doc: asciidoctor: remove unnecessary require

[Felipe Contreras]

This file is loaded by asciidoctor, the module is already loaded.

In addition to being less redundant this fixes a problem while trying
use a development version of asciidoctor when the gem is available:

  $GEM_HOME/gems/asciidoctor-2.0.15/lib/asciidoctor.rb:51:
    warning: already initialized constant Asciidoctor::RUBY_ENGINE
  $HOME/asciidoctor/lib/asciidoctor.rb:52:
    warning: previous definition of RUBY_ENGINE was here
  ...

That's a bug in asciidoctor, but there's no need to trigger it.

[PATCH 09/12] doc: asciidoctor: refactor macro registration

[Felipe Contreras]

There is no need to execute extra code every time the process block is
called.

In Ruby the lexical scope is shared, so we can define variables in the
register block scope, and all the rest will inherit those variables.

Based on the doctype and basebackend one of three blocks is selected for
the inline_macro. However, the conditionals will be run only once.

In the end Ruby will only run the code between `process do end`, nothing
else.
