The "highlight" code is very sensible to the order of the hash keys,
but the order of the keys cannot be predicted. It generates
faulty DocBook entries like:
- @<function>device_for_each_child</function>
Sorting the result is not enough some times (as it's deterministic but
we can't control it).
We should use an array for that job, so we can guarantee that the order
of the regex execution on dohighlight is correct.

OK, I've spent a bunch of time with this, comparing the results before
and after. The output you mention is clearly wrong, but there might be
room to differ over what the root cause is.
That output is caused by @device_for_each_child() in the comments. This
happens for a few other functions as well, and I think it's wrong. @ is
used to indicate parameters (or structure fields); I'm not sure why
people are using it for functions that are *not* one of the above.
Formatting the function names as a parameter doesn't seem right either.
There is the occasional case where the parameter *is* a function and the
text uses the () notation (threadfn(), for example). Having the
"parameter" style win out over the "function" style in such cases is OK,
I guess, but it would be good to format the parentheses along with the
name. The function patterns there now drop the parentheses entirely,
which seems a bit strange to me.
I guess I'll apply the patch; determinism is good, and it doesn't make
anything screwy that wasn't already that way. But I think we should fix
the misapplied @s and sort out function formatting in general. One of
these days...
Thanks,
jon

Shouldn't kernel-doc print a warning for syntactic mistakes like this
rather than silently accomodating to it in whatever way?
As to the usage of markdown in general, there's documentation coming up
for vga_switcheroo which makes use of that so I'd love to see it merged:
https://github.com/l1k/linux/commit/d1476d748b5f1adf5bffe8e0a8bafad1e879d22f
https://github.com/l1k/linux/commit/11c55ae65788162970d8fa23cd1fd2518af55d34
The large set of dependencies pulled in on Fedora is likely to be blamed
on the RedHat packaging being notoriously coarse-grained. By comparison,
Debian is extremely fine-grained, kind of the opposite extreme, and
therefore has comparatively few prerequisites:
https://packages.debian.org/jessie/pandoc
I do agree however that alternative tools with fewer dependencies should
be supported and it would be great if the markdown patches were amended
to that end.
Best regards,
Lukas

* [PATCH 2/6] scripts/kernel-doc: Adding infrastructure for markdown support

Markdown support is given by calling an external tool, pandoc, for all
highlighted text on kernel-doc.
Pandoc converts Markdown text to proper Docbook tags, which will be
later translated to pdf, html or other targets.
This adds the capability of adding human-readle text highlight (bold,
underline, etc), bullet and numbered lists, simple tables, fixed-width
text (including asciiart), requiring minimal changes to current
documentation.
At this moment, pandoc is totally optional. Docbooks ready for markdown
should be added to the MARKDOWNREADY variable inside the Makefile. In
case the developer doesn't have pandoc installed, Make will throw a
warning and the documentation build will continue, generating
simple Documentation without the features brought by pandoc.

@ 2015-09-07 20:02 ` Danilo Cesar Lemes de Paula

Markdown support is given by calling an external tool, pandoc, for all
highlighted text on kernel-doc.
Pandoc converts Markdown text to proper Docbook tags, which will be
later translated to pdf, html or other targets.
This adds the capability of adding human-readle text highlight (bold,
underline, etc), bullet and numbered lists, simple tables, fixed-width
text (including asciiart), requiring minimal changes to current
documentation.
At this moment, pandoc is totally optional. Docbooks ready for markdown
should be added to the MARKDOWNREADY variable inside the Makefile. In
case the developer doesn't have pandoc installed, Make will throw a
warning and the documentation build will continue, generating
simple Documentation without the features brought by pandoc.

This only seems to be applied to our (drm-intel) topical branch,
otherwise would've sent a patch.

s/propper/proper/
This only seems to be applied to our (drm-intel) topical branch,
otherwise would've sent a patch.

* [PATCH 3/6] drm/doc: Convert to markdown

DRM Docbook is now Markdown ready. This means its doc is able to
use markdown text on it.
* Documentation/DocBook/drm.tmpl: Contains a table duplicated from
drivers/gpu/drm/i915/i915_reg.h. This is not needed anymore
* drivers/gpu/drm/drm_modeset_lock.c: had a code example that used
to look pretty bad on html. Fixed by using proper code markup.
* drivers/gpu/drm/drm_prime.c: Remove spaces between lines to make
a proper markup list.
* drivers/gpu/drm/i915/i915_reg.h: Altought pandoc supports tables,
it doesn't support table cell spanning. But we can use fixed-width
for those special cases.
* include/drm/drm_vma_manager.h: Another code example that should be
proper indented with four spaces.

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.

* [PATCH 6/6] scripts/kernel-doc: Processing -nofunc for functions only

Docproc process EXPORT_SYMBOL(f1) macro and uses -nofunc f1 to
avoid duplicated documentation in the next call.
It works for most of the cases, but there are some specific situations
where a struct has the same name of an already-exported function.
Current kernel-doc behavior ignores those structs and do not add them
to the final documentation. This patch fixes it.
This is non-usual and the only case I've found is the drm_modeset_lock
(function and struct) defined in drm_modeset_lock.h and
drm_modeset_lock.c. Considering this, it should only affect the DRM
documentation by including struct drm_modeset_lock to the final Docbook.

Docproc process EXPORT_SYMBOL(f1) macro and uses -nofunc f1 to
avoid duplicated documentation in the next call.
It works for most of the cases, but there are some specific situations
where a struct has the same name of an already-exported function.
Current kernel-doc behavior ignores those structs and do not add them
to the final documentation. This patch fixes it.
This is non-usual and the only case I've found is the drm_modeset_lock
(function and struct) defined in drm_modeset_lock.h and
drm_modeset_lock.c. Considering this, it should only affect the DRM
documentation by including struct drm_modeset_lock to the final Docbook.

OK, I've spent a while looking this stuff over. I like the general idea,
but I do have a couple of concerns.
1 Installing pandoc on a Fedora system wants to drag in 70(!) packages
for 100MB of total stuff. Installing it on Arch is ... well ... enough
to make you want to switch to Fedora. If we add a dependency on a tool
this massive, people are going to complain, loudly.
Have you looked at using something like cmark instead? I don't know
the tool well, but it seems like it can do the job simply enough. It's
focused, written in C, and doesn't drag in a diskful of Haskell
stuff. There's lot of other converters out there too, I'm not tied to
this one (though I think CommonMark deserves support), but I do think
this question needs to be considered.
2 We're constructing an increasingly complicated document-processing
mechanism with a lot of independently moving parts. What if we
converted the whole document to markdown and dispensed with the XML
part altogether? Making the source files simpler and dispensing with
the xmlto requirement would be a big win, IMO.
I will not make #2 be a precondition to getting some form of this work
merged, but I would like to have a good answer for #1. Adding such a
heavyweight dependency (even as an optional one) needs to have a pretty
good story behind it.
Thanks,

Personally I don't care which kind of text markup we pick and wich
converter, as long as the project looks reasonable far away from
immeninent death (way too many one-person projects on github in this
area).
But if we have this discussion I'd like to decouple it from the other
kerneldoc improvemnts in this series (patches 1, 5 and 6). If we cant
agree on the text markup then drm docs will simply look a bit funny for
everyone else. But if the inline struct stuff won't happen 0-day will
scream around (and there's already patches which use the new layout).

Who's going to convert the almost 30kloc of xml template (which often have
large amounts of texts) and the over 60k kerneldoc comments that we have
already?

Should we discuss #1 at ks? Imo as long as no one pipes up to do the
massive conversion away from the current toolchain (and subsystem
maintainers won't just kill that effort because it causes too much churn)
moving forward with the kerneldoc toolchain we have makes sense. Hence I'd
like to see those patches landed before we resolve #1 if possible.

Those patches are:
1) scripts/kernel-doc: Replacing highlights hash by an array
5) scripts/kernel-doc: Improve Markdown results
6) scripts/kernel-doc: Processing -nofunc for functions only
#1 is fine, I'll merge that today. #6 is already merged. #5 is a markdown
patch, though, and doesn't make sense without the others? Are you thinking
about #3 (drm/doc: Convert to markdown)? That one would almost work (it
depends on #2 currently) and it nicely shows *why* I'd like to get away from
XML...

I thought you'd do that :)
Seriously, though, a change would be a big job. There's a reason I've said
several times that it would make no sense to delay the work at hand in the
hopes of somebody doing this whole job instead. But we can certainly
ponder what might be better.
Getting rid of the XML stuff may well simplify the whole process and make
the documentation much more accessible for those who would change it; that
could be a goal worth going for. Oh, and anything requiring changes to the
kerneldoc comments is going nowhere, that was never something I'd
contemplated. Those comments are fine.
But any such change needs a lot of thought and a reasonable proof of
concept. Meanwhile we have work that can make the docs better now, and I
want to merge it. But we should choose the tools we use carefully, and I
anticipate a lot of opposition to one that has to drag in 70 Haskell
packages with it.

I've tossed the topic out there; the kernel summit agenda hasn't been made
yet, though. In any case, I'd be happy to resolve this particular issue
before then if it were possible.

Sorry I mixed things up, #5 is ok to leave out. I thought about
"scripts/kernel-doc Allow struct arguments documentation in struct
body" but you already merged that one for 4.2. Which I missed, but
which is great since that's the one that would cause the big
conflicts.

Well my goal is to be able to have all the programmer docs in the
code, including any high-level overview sections to tie everything
together (hence hyperlinks and better formatting). But then you still
need some skeleton to make a coherent whole out of all the parts, and
I think the docbook xml templates we have serve rather fine for that
role. Writing text in xml is indeed horrid, but if we can create
in-line DOC: sections with decent formatting there's really no need
for that. From that angle this work here already has the goal to get
rid of the xml - I plane to move all the existing text in the drm.tmpl
xml into inline DOC: kerneldoc commets.
And at least gtkdoc (which we use extensively for the userpace
test/tools repo) relies on some xml thing to tie different topics
together too. So that seems pretty standard.

Well personally I don't care about the exact tooling, as long as:
- it's a reasonable alive project
- packages available on distros (works for me on both debian and fedora)
- we can muck around with how things are integrated into overall docs
(which is the case since pandoc is only used as a paragraph formatter
here).
The last one is something we stumbled over for the userspace side
where we wanted to have better tooling for documenting testcases.
Upstream gtkdoc is receptive, but getting anything in takes forever
and then there's the 6 month release schedule too. And there's also
the problem that we can't change the kerneldoc grammar (e.g. gtkdoc
has the code comment parser integrated and ofc it has slightly
different rules to mark up references to structs/enums).
I'm also trying to build up a doc team here with a full-time tech
writer for drm/i915 topics. So I'm very much interested in keeping
this all alive. But I don't have the time to mass-convert everything
else, and I'm also not sure it's a good idea: In my experience all the
doc toolchain suck somewhat, and it's better to be consistent within a
project instead of proliferating different solutions. It's hard enough
already to get developers to write docs and even harder to find
someone who writes good docs ...
Ofc we already have a big split between the ad-hoc text files in
Documentation and the docbook stuff in Documentation/DocBook. Otoh
docbook is the only way to extract the kerneldoc comments into
something readable and indexed.

I don't mind much if we delay this part until KS. All the text markup
styles are pretty close. So fixing up one dialect for another for the
few patches I'll likely pull in for 4.4 won't be a lot of work if we
decide to go with something else. Or even if we decide to switch
markup styles much later, it should all be doable with a few sed jobs.
Only problem I see is that thus far no one else seems to care much,
and if we change the approach I need to convince management here again
that we need to invest some time to make it happen (and some excuses
why this approach here wasn't ok). That will probably suck down more
time than converting to whatever we decide on. And like I said I
personally don't care one bit what the toolchain looks like or the
exact flavour of text markup we pick.
Cheers, Daniel

I wouldn't care either. I choose pandoc as it's old, kind of stable and
has a decent community around it, so it won't probably die due the lack
of interested developers.
That said, cmark is not a option (at least for now). With the current
approach we need a tool capable of reading markdown text and output
DocBook tags, as we're actually still using docbook to spit all kinds of
Documentation formats (html, man, pdf). Looks like cmark can only do
markdown->html.
I did look into other options though, but they were all mostly one-man
job. But yeah, basically any tool capable of converting
markdown->docbook will work. I'm always listening to suggestions =)

#5 is the DRM markdown conversion, which depends on #2 and #4. So if a
decision about this is going during KS, we need to hold those three patches.

I wouldn't care either. I choose pandoc as it's old, kind of stable and
has a decent community around it, so it won't probably die due the lack
of interested developers.
That said, cmark is not a option (at least for now). With the current
approach we need a tool capable of reading markdown text and output
DocBook tags, as we're actually still using docbook to spit all kinds of
Documentation formats (html, man, pdf). Looks like cmark can only do
markdown->html.
I did look into other options though, but they were all mostly one-man
job. But yeah, basically any tool capable of converting
markdown->docbook will work. I'm always listening to suggestions =)

#5 is the DRM markdown conversion, which depends on #2 and #4. So if a
decision about this is going during KS, we need to hold those three patches.
