[Buildroot] [PATCH 0 of 4 v2 for 2014.08] manual-text generation improvements

[Thomas De Schampheleire]

This patch series makes some improvements to the generation of the text
version of the manual:
- make sure that URLs are visible
- remove the 'logo' (logo.png) reference

To achieve this, two preparatory patches are needed.

Note that this series stands on its own, it can already be applied.
A subsequent series will make structural and content-wise changes to the
manual itself.

[Buildroot] [PATCH 1 of 4 v2 for 2014.08] gendoc infra: use $(pkgname) instead of explicitly passing 'manual'

[Thomas De Schampheleire]

In the gendoc infrastructure, using an assignment of the form
    FOO = docs/$(1)/bar
inside GENDOC_INNER does not work as expected: the $(1) value is empty here
and the value of FOO becomes 'docs//bar'.

Parameters $(2), $(3), etc. do not have this problem. The specific thing
about $(1) is that it is a parameter to GENDOC itself (indicating the
document to create) and passed transparently to GENDOC_INNER.

This is different from the package infrastructures, where $(1) is set from
$(pkgname). In fact, the same strategy could be used by the gendoc
infrastructure as well, as $(pkgname) resolves to 'manual' for file
docs/manual/manual.mk. This has the advantage that the described problem
does not occur.

Note that this means that if we want to use the same GENDOC infrastructure
for another document, it will have to reside in a separate directory than
the manual.

This breaks generating the manual:

    $ make manual-html
    make: *** No rule to make target `manual-html'.  Stop.
    $ make manual
    make: *** No rule to make target `manual'.  Stop.

Did I miss something? Was that patch supposed to do that? ;-)

That's because $(pkgname) returns empty, because $(pkgdir) returns
empty, because I do not have a .config file.

So, before this patch, it was possible to build the manual from a
pristine Buildroot tree; now it is no longer possible.

I think that's bad.

Yann E. MORIN.

Agreed. The problem is that pkg-utils.mk is only
included when a config file is present.
Based on this, I see three possibilities:

1. Include pkg-utils.mk unconditionally from Makefile
 (currently included from package/Makefile.in)

2. Move the definition of pkgname and pkgdir to
 Makefile (outside the check on the config file)

3. Don't use pkgname/pkgdir for the manual
 generation rules, and try to solve the issue with $1 on
 a different way (I feel double dollar signs coming up
 somewhere...)

Best regards,
Thomas

I think option 1 is the best.

As far as I cn see, the only parts of pkg-utils that need a .config are
the INFLATE.XXX variables. The rest of the file can well live outside of
the HAS_DOT_CONFIG conditional.

But the same can be said of most other pkg-*.mk files that define
package infrastructures: the definitions in themselves do not need a
.config, not even the build rules in pkg-generic.mk.

Regards,
Yann E. MORIN.

[Buildroot] [PATCH 2 of 4 v2 for 2014.08] gendoc infra: add support for asciidoc configuration files

[Thomas De Schampheleire]

This patch introduces support for asciidoc configuration files, specific for
each output format (html, text, pdf, ...). This is useful to make certain
tweaks in the document generation.

If a file docs/manual/asciidoc-<format>.conf is present, it is passed to
asciidoc as configuration file. If no file for the current format is
present, the options passed to asciidoc are empty.

[Buildroot] [PATCH 3 of 4 v2 for 2014.08] manual-text: make sure URLs are displayed if a link text was provided

[Thomas De Schampheleire]

When the asciidoc source contain URLs of the form:
    http://example.com[An example website]
the text representation of the manual would only contain:
    An example website
without displaying the actual URL.

This patch adds an asciidoc configuration file that sets the inline macros
for several URL types so that the display becomes:
    An example website [http://example.com]
For URLs where no link text was provided, the display becomes:
    http://example.com
which is the same as before.

Signed-off-by: Thomas De Schampheleire <thomas.de.schampheleire@gmail.com>

---
v2:
- link to relevant documentation (which was hard to find)
- refine so that the display is identical to before when no link text is
  provided.

[Buildroot] [PATCH 4 of 4 v2 for 2014.08] manual-text: hide image representations

[Thomas De Schampheleire]

Images specified in the asciidoc sources (currently only the logo) are
displayed as the file name in the text version of the manual. This causes an
odd line to appear:
    logo.png

Avoid this by setting the image representation macros to {empty} in
manual-text.
