I have tested this by using diffoscope between the docs built by the
makefiles and by this Meson patchset, and verified they are all
identical.

There are both a new "doc" target (ninja doc) and a configuration
option. This is due to the following bug in Meson:
https://github.com/mesonbuild/meson/issues/4107
because of it it's not possible to have simply an optional target,
as its files will not be installed.
So by default the documentation is off, if one wants to just build it
'ninja doc' can be used, but if one wants to both build and install
the config option 'enable_docs' has to be enabled.

A couple of small refactoring was done to the makefile doc build, to
make things easier and doable by both build systems.

Luca Boccassi (4):
  mk: use script to generate examples.dox
  mk: use templated doxygen config, modified on the fly
  build: use same version as make showversion in Meson
  build: generate API documentation with Meson

This will make it possible to generate the file in the same way from
Meson as well.

This will allow the same config file to be used from Meson.
The result has been verified to be identical via diffoscope.

make showversion will print 18.11.0-rc0 but Meson sets 18.11-rc0,
causing among other things a difference in the generated documentation.

Fixes: 76b9d9de5c7d ("version: 18.11-rc0")

Both a configuration-time "enable_docs" boolean option and an optional
'ninja doc' target are available. Note that due to a Meson bug for now
the latter will only build, but not install the files.

What is SC2129 ?

Good idea.
While at putting all in the same file (template),
we can re-organize the template a bit.

You use generate_doxygen.sh only with meson?
Shouldn't we use the same in mk/rte.sdkdoc.mk?

I was kinda hoping somebody would be able to suggest an alternative
that avoids the need for generate_doxygen.sh - the issue being that
with Meson's "custom_target" you can't specify a subdirectory in
input/ouput (and the directory is generated at build time so can't have
a meson.build in it), and also you cannot use the same "output" twice.

So I can't see a way to have an additional custom_target to run the CSS
generation, hence the script.

Changing the makefile to use the script will make it a bit more
complicated, as the doxygen file will need to be generated rather than
passed by piping stout/in, so the rule will have to be split into 3:
create directory -> create file -> call doxygen. Not sure it's worth
it?

Agree, rather than using continuation lines, I suggest one of the
following:
* use exec > ${API_EXAMPLES} at the top of the script
* let the script just print to stdout and have make/meson put that in the
  output file for you.

This needs to be inside a conditional if we are not building docs.
Otherwise overall build will error out if doxygen is missing - even if
unused.

This will make it possible to generate the file in the same way from
Meson as well.

This will allow the same config file to be used from Meson.
The result has been verified to be identical via diffoscope.

make showversion will print 18.11.0-rc0 but Meson sets 18.11-rc0,
causing among other things a difference in the generated documentation.

Fixes: 76b9d9de5c7d ("version: 18.11-rc0")

Thinking about it, I think that "required" should be set to
"get_option(enable_docs)", since if someone explicitly enables the docs
they should be built and cause error if they can't be.

Suggestion: add a run_target in an else leg to just print out "no
doxygen found" or similar message when ninja doc is called.

This will make it possible to generate the file in the same way from
Meson as well.

This will allow the same config file to be used from Meson.
The result has been verified to be identical via diffoscope.

make showversion will print 18.11.0-rc0 but Meson sets 18.11-rc0,
causing among other things a difference in the generated documentation.

Fixes: 76b9d9de5c7d ("version: 18.11-rc0")

v2: made doxygen dependency optional, skip doxygen build when not found
v3: made doxygen dependency mandatory if enable_docs is true, add
    alternative doc target that prints "doxygen not found" when doxygen
    is not found and enable_docs is false (default)

While I suggest we keep this in this patchset for now, this isn't going to
scale as we add in more targets for building the PDF/HTML guides. I think
for that case, we may need to use an array variable for the "depends"
target, and add things to that as we process the documentation meson.build
files. That might work better for cases where we have some but not all doc
build capabilities, e.g. missing sphinx but not doxygen.

And the main reason I don't recommend changing this yet, is that until we
add in the extra doc builds we probably won't know what the result needs to
look like anyway, so little point in just guessing what the solution would
be.

Yeah that makes sense, I can rework that once the sphinx stuff is also
in.

Did you manage to get it working yet?

This will make it possible to generate the file in the same way from

This will allow the same config file to be used from Meson.
The result has been verified to be identical via diffoscope.

  To: dev; +Cc: bruce.richardson, john.mcnamara, marko.kovacevic, thomas

make showversion will print 18.11.0-rc0 but Meson sets 18.11-rc0,
causing among other things a difference in the generated documentation.

Fixes: 76b9d9de5c7d ("version: 18.11-rc0")

v2: made doxygen dependency optional, skip doxygen build when not found
v3: made doxygen dependency mandatory if enable_docs is true, add

    is not found and enable_docs is false (default)
v4: add acked-by

make showversion will print 18.11.0-rc0 but Meson sets 18.11-rc0,
causing among other things a difference in the generated documentation.

Fixes: 76b9d9de5c7d ("version: 18.11-rc0")

v2: made doxygen dependency optional, skip doxygen build when not found
v3: made doxygen dependency mandatory if enable_docs is true, add
    alternative doc target that prints "doxygen not found" when doxygen
    is not found and enable_docs is false (default)
v4: add acked-by
v5: change install directory to $PREFIX/share/doc/dpdk to match legacy
    makefiles
