These were using gimp_procedure_new, which was causing warnings like
LibGimpConfig-WARNING **: 13:56:33.270: couldn't serialize property
GimpProcedureConfig-plug-in-metadata-editor::image of type GimpImage,
and
gimp_plug_in_destroy_proxies: ERROR: GimpImage proxy with ID 1 was
refed by plug-in, it MUST NOT do that!
This also saves us from having to define image and run-mode parameters
ourselves.
If we leave a space between the macro name and opening parenthese for argument
lists, the args are not considered macro args (which will be discovered when
using it). I experienced this issue while testing code on some plug-in
yesterday, so thought I might as well fix all these broken macros for casting to
the specific GimpPlugIn subclass, so that we won't have a next time.
The metadata-viewer uses a GtkBuilder .ui file to create the interface.
In GIMP we prefer our interfaces to be created in code and these builder
files are also not available anymore in GTK4.
This commit removes the .ui file and support code, and creates the
interface from code in our plug-in.
This is the consequence of previous commit. Plug-ins' label and
documentation are now localized before sending these data to GIMP core.
In other words, we replace N_() macros with basic gettext calls.
Hence avoiding the stderr messages. These are going to be localized with
centrally installed catalogs "gimp*-std-plugins", "gimp*-script-fu" and
"gimp*-python".
We now handle core plug-in localizations differently and in particular,
with kind of a reverse logic:
- We don't consider "gimp*-std-plugins" to be the default catalog
anymore. It made sense in the old world where we would consider the
core plug-ins to be the most important and numerous ones. But we want
to push a world where people are even more encouraged to develop their
own plug-ins. These won't use the standard catalog anymore (because
there are nearly no reasons that the strings are the same, it's only a
confusing logic). So let's explicitly set the standard catalogs with
DEFINE_STD_SET_I18N macro (which maps to a different catalog for
script-fu plug-ins).
- Doing something similar for Python plug-ins which have again their own
catalog.
- Getting rid of the INIT_I18N macro since now all the locale domain
binding is done automatically by libgimp when using the set_i18n()
method infrastructure.
We were using parameter iter in metadata_dialog_add_tag and
metadata_dialog_add_translated_tag.
However, iter is only ever set inside metadata_dialog_add_tag by calling
gtk_list_store_append. So, there is no need to pass this parameter around.
For this reason, let's remove parameter iter from the above two functions
and replace with a local variable.
Since we increased our minimum version of gexiv2 to 0.12.3, several
functions used in the metadata-viewer plug-in have been deprecated.
Replace these functions with the "try_" versions, which include an
error parameter. If this returns non NULL then we print the error
message to the console.
XMP tags that have multiple values (usually of type XMpBag or XmpSeq) were
shown on one line. Which, especially for long text values, could make it
difficult to see the separate values for that tag.
Let's do the same as we do for IPTC tags that can occur multiple times and
show each value on a separate line.
In the metadata-viewer refactor the code that adds multiple values per tag
to the list store into a separate function.
Currently used for IPTC tags only but the intention is to reuse it for
XMP tags with multiple values.
Let's increase the default size of the metadata viewer a bit.
Ideally we would add some logic to determine the width of
the first column since that one currently depends on the
length of the longest tag. However for now this change
will be enough for most cases.
metadata-editor and metadata-viewer did return GIMP_PDB_SUCCESS when
loading the dialog ui failed, we changed this to GIMP_PDB_EXECUTION_ERROR
and now use a GError to report it back to GIMP.
In metadata-editor also improve the error handling when loading the calendar
dialog fails.
The error also only showed in the console so change that to show a dialog
or the error console.
Adding metadata-tags to meson.build and Makefile.am for
the metadata-viewer since until now it was only used in
the metadata-editor.
The Exif gps metadata tags for longitude, latitude and
altitude get special handling to show them with more
precision and let the string parts be translated.
Turn all ID param specs into object param specs (e.g. GimpParamImageID
becomes GimpParamImage) and convert between IDs and objects in
gimpgpparams.c directly above the the wire protocol, so all of app/,
libgimp/ and plug-ins/ can deal directly with objects down to the
lowest level and not care about IDs.
Use the actual object param specs for procedure arguments and return
values again instead of a plain g_param_spec_object() and bring back
the none_ok parameter.
This implies changing the PDB type checking functions to work on pure
integers instead of IDs (one can't check whether object creation is
possible if performing that check requires the object to already
exist).
For example gimp_foo_is_valid() becomes gimp_foo_id_is_valid() and is
not involved in automatic object creation magic at the protocol
level. Added wrappers which still say gimp_foo_is_valid() and take the
respective objects.
Adapted all code, and it all becomes nicer and less convoluted, even
the generated PDB wrappers in app/ and libgimp/.
The new metadata viewer is based on a version of the old metadata
plugin that still contained this bug, and a few other bugs that've
been fixed since then. Reapply those fixes to the new plugin.
This is essentially an adaptation of commits
f8e291bf31,
ce9e7feabd,

and 801bd8fb3f.
