Virtual functions may use input/output parameters but this is not currently
well handled by gjs, so adding test cases to gobject-introspection to verify
that virtual functions correctly receive valid input values and can return
them.

Comparing floats directly doesn't always work on all architectures.

cElementTree was removed in Python 3.9 in favor of ElementTree,
which has used a fast, native implementation since Python 3.3.

When gobject-introspection-1.0 pkg-config is not found on the system,
Meson can fallback to configure g-i as subproject and needs a dependency
object to replace the pc file.

The dependency file needs to ensure that typelibs are created before
compiling any other gir and provide the girdir for files within build
directory. It also need to provide glib dependencies required to compile
girs.

Bump Meson version to 0.54.0 to use meson.override_dependency().

This reverts commit ec00edd9.

The nightly run time does not have Meson 0.54.

GTK4 allows adding widget-related actions to the documentation with the
newly defined syntax:

  <class_name> '|' <action_name> ':'

This means g-ir-scanner needs to detect this new format, to avoid
emitting unnecessary warnings.

Currently, we don't do anything with the actions; in the future we might
want to add them to the documentation in the GIR, but for that we'd need
a new element.

GListModel is an interface for creating typed, list-like containers. The
data stored is GObject instances, but it's useful to be able to annotate
the actual type, for both documentation and code generation purposes.

Fixes: #328

We need to special case the ListModel container type in the
documentation writer so that we don't fall back into array/list
automatic conversion in the code snippets.

GListModel is an interface for creating typed, list-like containers. The
data stored is GObject instances, but it's useful to be able to annotate
the actual type, for both documentation and code generation purposes.

The annotation should be optional, to maintain backward compatibility.

Checking the Python dependency doesn't ensure the header is present.
That needs to be checked separately.

Required for adding new API to the 1.66 series.

This functionality is used in both PyGObject and GJS, and if not done
correctly can lead to architecture-specific bugs. It seems best to add
API in gobject-introspection for the correct way to do it.

See also: GNOME/gjs#309

We are adding new API for 1.66, so bump the version number to the
development series.

Actually, we shouldn't really need this. We are building `native: false`
binaries so when we look up a `native: true` binary the override should
not apply. I've fixed this upstream in meson in
https://github.com/NixOS/nixpkgs/pull/86080, though some backwards
compatibility migration might be in order.

In the meantime, we can make `gi_cross_use_host_gi` prevent the
overrides from happening, which will achieve the desired behavior.

Finally, this allows us to use `find_program` in `scanner_command`,
unconditionally, letting the presence of the override dictate whether a
freshly-built or pre-built `g-ir-scanner` is used.

meson.build_root() is the root of the main project, better use
meson.current_build_dir() instead.

The newest flake8 has started to detect this.

In case a user had a combination of -fvisibility=hidden, -Wl,--as-needed, -flto, -O2
in the CFLAGS the linker would sometimes detect that all the referenced gtype functions
weren't actually used and throw them out with their providing libraries.

Instead of hoping that the user's CFLAGS don't mess without our symbol visibility just use
G_MODULE_EXPORT on the two symbols which reference all other gtype and gquark symbols.

This fixes errors such as:

Invalid GType function: 'gtk_accel_group_get_type'
Failed to find symbol 'gtk_accel_group_get_type'

during the g-ir-scanner execution.

`g_win32_output_stream_new_from_fd()` is private in Gio. 

It's normally not exported unless `GLIB_STATIC_COMPILATION` is effective.
PS. Why would i not be called `GIO_STATIC_COMPILATION` for Gio .c-files?

There has been no backwards incompatible changes between DockBook 4.3
and 4.5 so there is no need to use both.

Ideally, we would switch to DocBook 5 but that will require more changes.

meson inserts the dependency if the compiler is used directly, but
fails to do so if the compiler is run through a wrapper. This leads
to build race errors between building the compiler and using it.

On Windows and Cygwin builds, we need to put the '.exe' for our entries

otherwise Meson will not be able to identify these programs correctly.

There was previously no mechanism for tagging enum members
and struct fields with Since tags (or other, eg deprecation tags).

While the customary place to add Since tags for these symbols
is inline in the parent symbol's documentation eg:

/**
 * Foo:
 *
 * @FOO_BAR: some bar. Since X.Y
 */

And variations on that theme, implementing parsing for that scheme
would result in a pretty ambiguous grammar, especially if we also
want support for multiple tags.

Instead, the solution implemented here is to allow providing
documentation for individual members and fields through their
own separate block, as is done for virtual functions already.

Inline comments are still used, with a lower precedence.

Fixes #348

Up to now, section annotations had to match a class or interface
name in order to be serialized in the gir.

With this commit, they now get serialized as docsection nodes,
for potential use by documentation tools.

This adds quick support for using 'clang-cl' (CLang's emulation of the Visual
Studio compiler) to run giscanner.

This will still initialize things mostly in the MSVC fashion, except that it
will also check whether both 'CC' and 'CXX' envvars are set to
'clang-cl [args]', as per the way that Meson supports using 'clang-cl'.

Since we are using distutils to set up the compiler instance, when we enable
'clang-cl' support, we trick distutils that we have already initialized the
MSVCCompiler parameters as needed.  We just leave out the compiler flags as
we don't really care about debug symbols nor optimization with the built
dumper binary, as it is gone as soon as the .gir file is generated.

This will build G-I successfully with all the tests passed.

Let people know how building G-I and running g-ir-scanner with clang-cl and
friends is being supported, as this support is now added.

When writing documentation to the GIR files, GIR tries to match
classes with their matching SECTION: comment in the source code. Some codebases
use kebab-case or CamelCase for their section names, but GIR always expects
them to be flatcase or the matching will fail.

This commit converts all section names to flatcase (by removing "-" and
converting to lowercase) while they are being parsed, so that they are matched
properly later on.

Fixes #350.
