[PATCH] scripts/kernel-doc: Improve Markdown results

[Danilo Cesar Lemes de Paula]

Using pandoc as the Markdown engine cause some minor side effects as
pandoc includes  main <para> tags for almost everything.
Original Markdown support approach removes those main tags, but it caused
some inconsistencies when that tag is not the main one, like:
<something>..</something>
<para>...</para>

As kernel-doc was already including a <para> tag, it causes the presence
of double <para> tags (<para><para>), which is not supported by DocBook
spec.

Html target gets away with it, so it causes no harm, although other
targets might not be so lucky (pdf as example).

We're now delegating the inclusion of the main <para> tag to pandoc
only, as it knows when it's necessary or not.

That behavior causes a corner case, the only situation where we're
certainly that <para> is not needed, which is the <refpurpose> content.
For those cases, we're using a $output_markdown_nopara = 1 control var.

Hey Jonathan,

Did you find time to check this patch? As you mentioned that you applied
the Markdown support for the linux-next tree, this patch might be needed
(maybe "wanted" is a better word).

Intel guys are working on improving documentation and I believe they
need this.

Thanks,

Hey Jonathan,

Did you find time to check this patch? As you mentioned that you applied
the Markdown support for the linux-next tree, this patch might be needed
(maybe "wanted" is a better word).

Intel guys are working on improving documentation and I believe they
need this.

Thanks,

Danilo

Not quite what I said...I said I'd apply it right after the merge window
so it can sit in linux-next through the full cycle.  It's a bit early to
be pushing 4.4 stuff into linux-next now...

Beyond that, I wasn't sure where things stand with fixes... Can you send
me a new patch set with this fix (and any others that might
exist) integrated in?

Thanks,

jon

Sure, but I'm a bit confused now (kernel noob here).

In the last few days I sent three features:
Markdown support (patch series 1)
Cross-reference hyperlink support (patch series 1)
in-struct-body documentation (series 2)

I assume you want a new patch series for the series 1, containing the
feature itself and the fixes that I sent later, correct?

Thanks,

Danilo

The cross-reference patch was merged, so there's no need to send that
again.  Anything else that isn't in mainline now should be resent as a
new series.

I did send a new set, named "[PATCH 0/6] scripts/kernel-doc: Kernel-doc
improvements"
I did include all the patches I didn't find in mainline.
Is it enough?

Thanks,

Danilo
