* RNA_blender.h is now generated along with the other files. It is not
used anywhere yet, and still located quite hidden next to the other
rna_*_gen.c files. Read only access for now.
* Inherited properties are not copied from the base anymore but
iterated over. Patch by Vekoon, thanks!
* Array get/set callbacks now do the whole array instead of getting an
index. This is needed for some layers for example so python can set
the array as a whole, otherwise the check that one layer has to be
enabled at all times gets in the way. Also nicer for the C API.
* Also some changes to returning pointers to make the API cleaner, got
rid of the type() callback and instead let get() return PointerRNA
with the type included.
The C API looks like this currently:
http://users.pandora.be/blendix/RNA_blender.h
* Fixed bug in with RNA-paths. String identifiers (i.e. some_collection["somekey"]) were not getting handled at all due to wrong indices it seems. I don't know of any other code using this, so hopefully there aren't any unintended bugs caused by this.
This means that bone animation now works again.
* Added a few more sanity checks to file-reading code, and heaps of extra prints everywhere else for debugging purposes (these will be removed in due course).
(when in debug "-d" mode only)
copy & paste duplicate and transform operations can now be copied from user input and pasted into ./test.py and run with the Pkey (fixed some minor bugs preventing this)
Would be nice if the "mode" setting used a proper RNA Enum rather then an int.
# example, duplicate and transform
bpyoperator.OBJECT_OT_add_duplicate(mode=1)
bpyoperator.TFM_OT_transform(mode=1, options=0, values=(-1.23989, 0.570745, 0, 0), constraint_orientation=0, constraint_mode=0, constraint_matrix=(0, 0, 0, 0, 0, 0, 0, 0, 0))
* Work around bScreen/Screen DNA name patching, so bScreen does not
require manual callbacks to be written for properties.
* Added SpaceLink and SpaceImage RNA.
* Fix issue initializing ID property arrays with default values.
DNA
* Some DNA changes for space image.
* And a fix for corrupt clone image pointer in reading brushes.
* Finished DNA_lamp_types.h, DNA_world_types.h and DNA_sound_types.h.
* Renamed "parent" struct property to "nested", and also remaining "from"
usage to "base".
* Added a NEVER_NULL subtype for pointers and use it for all properties
that apply.
* Make sure all structs have a description, and fix any other DOC_BROKEN
descriptions, also many other naming consistency improvements.
* Object has some more properties wrapped, mostly game related.
* Scene frame changes now send a notifier.
* Added functions to create/free operator properties for calling
operators. This also simplifies some duplicated code that did
this. Ideally though this kind of thing should use the properties
pointer provided by buttons and keymap items. Example code:
PointerRNA ptr;
WM_operator_properties_create(&ptr, "SOME_OT_name");
RNA_int_set(&ptr, "value", 42);
WM_operator_name_call(C, "SOME_OT_name", WM_OP_EXEC_DEFAULT, &ptr);
WM_operator_properties_free(&ptr);
* Added support for sending notifiers and updates when setting
RNA properties. Per property, there is a notifier NC_/ND_ flag,
and a function that is called. Currently only used for
Object.loc/rot/size.
* RNA_property_update that does this is not automatically called
in every _set function, it has do be done separate, and is being
done by buttons with RNA data.
* Perhaps for python there could be a trick to accumulate these
flags rather than update each time, though for now the python
RNA code could just do them everytime. Did not add these calls
in the python code yet because it needs context, not sure where
to get that from?
* Store RNA collections different in ID properties, using a generic
ID property array, using the patch provided by Joe.
* Fix bug accessing registered operator properties in the wm from the
outliner.
* In the outliner, only use the RNA icon for RNA data, and use dot
again for unknown icon.
* Also, show pointer properties data in the second column, and auto
expand two levels when opening them.
* Added small RNA_struct_defined_properties function to get only the
defined properties without builtin and undefined id properties
(for py operators).
* Added support for using pointers + collections as operator properties,
but with the restriction that they must point to other type derived from
ID property groups. The "add" function for these properties will allocate
a new ID property group and point to that.
* Added support for arrays with type IDP_GROUP in ID properties.
* Fix bug getting/setting float array values.
Example code for collections, note the "OperatorMousePath" type is defined
in rna_wm.c and has a float[2] property named "loc".
Defining the operator property:
prop= RNA_def_property(ot->srna, "path", PROP_COLLECTION, PROP_NONE);
RNA_def_property_struct_runtime(prop, &RNA_OperatorMousePath);
Adding values:
PointerRNA itemptr;
float loc[2] = {1, 1},
RNA_collection_add(op->ptr, "path", &itemptr);
RNA_float_set_array(&itemptr, "loc", loc);
Iterating:
RNA_BEGIN(op->ptr, itemptr, "path") {
float loc[2];
RNA_float_get_array(&itemptr, "loc", loc);
printf("Location: %f %f\n", loc[0], loc[1]);
}
RNA_END;
* WM_operator_pystring to print the python func+args for an operator
* call WM_operator_print(op) in wm_operator_invoke(), simple echo mode should be moved later.
* added ED_SCRIPT_OT_run_pyfile that takes a filename argument.
* RNA_property_string_set didn't add a value to ID props if the prop wasnt there (like ints, floats and bools do)
* bpy_operator.c - raise an error when unknown keyword args are passed to any operator .
Examples of bpy operator api...
bpyoperator.ED_VIEW3D_OT_viewhome(center=1)
bpyoperator.ED_SCR_OT_frame_offset(delta=10)
bpyoperator.ED_VIEW3D_OT_make_parent(type='OBJECT')
At the moment there is no way to stop the operators .invoke() function from running so ED_VIEW3D_OT_make_parent still opens the menu even though it doesn't need to.
Further simplifying making operators with menus;
now you can add an 'invoke' callback:
WM_menu_invoke
which will automatically generate a menu with choices and assign
it to the property 'type'.
What also helps typing is the new RNA_enum_is_equal() function.
Here's a paste of the now committed 'clear parent'. Note the
undo push will become a flag too.
http://pasteall.org/3660
(Brecht; fixed small bug in RNA_enum_is_equal!)
To evaluate: solving dependencies for multipe scenes... probably
will make a more generic flush call.
* Added support for defining properties for operator buttons, with
uiButGetOperatorPtrRNA. Needed to cleanup a hack that was there
for operator properties in RNA, now a separate OperatorProperties
type is used for storing operator properties, instead of being part
of the Operator type itself.
* Allow selecting menu items with mouse release instead of press again.
* Fix some cases with hanging tooltips in the UI.
Added some functionality to make inspecting all RNA structs possible. Not used
yet, but can be tested by replacing this line in space_outliner.c:
RNA_main_pointer_create(G.main, &cell.ptr);
with:
RNA_blender_rna_pointer_create(&cell.ptr);
* RNA_property_enum_value
* RNA_property_enum_identifier
To get an enum string from a value and a value from an enum.
BPy_StructRNA types (objects, meshes, images etc) can now be used as dictionary keys.
* Fix sensor data pointer code, also made sensor type non editable,
would need to do more work than just setting the type.
* Fix a fairly obscure bug related to inheritance and sorting.
* Complete DNA_ID.h wrapping, just a few extra properties and the
Library struct, most of this is internal.
* Added more lamp properties. (patch by Michael Fox)
* Fix a number of warnings in the RNA code.
* Converted DOS line endings to UNIX.
* Added some information on defining ID structs, and fixed use
of "ID" inheritance for some non-ID structs.
* Added text on naming conventions to the RNA documentation, and
applied it to the current code.
http://wiki.blender.org/index.php/BlenderDev/Blender2.5/RNA#Naming_Conventions
* Made auto collection wrapping work for ** arrays.
(Mesh.mats, still points to ID since there is no Material yet).
* Added sorting of RNA structs/properties before writing.
* Disable editable pointers for now, difficult to support well.
* Swap parameters in RNA_access.h functions to make it more
consistent.
* Rename rna members for operators to wmOperatorType.srna, and
wmOperator.ptr, to make the distincton a bit clearer.
• Removed the RNA_int_default and similar functions, they're too
confusing. RNA_property_is_set can still be used to achieve
the same goal.
* Add functions to create RNA pointers.
Some example code for RNA data access and operator properties:
http://wiki.blender.org/index.php/BlenderDev/Blender2.5/RNAExampleCode
* Wrap most user editable data in DNA_mesh_types.h and DNA_meshdata_types.h.
Still needs to be improved in some areas though, especially how to deal
with data layers (expose per element or as array, or both?), and data in
face corners (bmesh type data structures are more logical here).
Tweaks to RNA defining to make some cases easier:
* Added range callback function for int/float.
* Added 'skip' callback for listbase and array iterators to skip items in
the collection.
* Extra error print when calling wrong define_property_*_sdna functions.
* Also made button code respect non_editable flag, is quick change though,
need to add support for properly graying out etc.
* Added RNA for operators. This still uses ID properties internally,
but through the RNA API now. The OP_get/set_* API that was used is
replaced by the RNA API. Currently RNA properties for operators are
defined at runtime since it means operator registration can be done
in a single function.
* Changed the existing operators to use this system, I haven't defined
user interface names yet though. I also think there need to be some
conventions on which properties to expose to make these operators
usable in macros, for example if mouse coordinates should be stored
or not.
* When using ID properties through defined RNA properties, it now
checks that the ID property actually matches the RNA property and
removes/overwrites it otherwise. This ensures that you can safely
get/set arrays for example without having to worry that some
external thing may have changed the length.
* Documentation now has some information on RNA + ID properties.
http://wiki.blender.org/index.php/BlenderDev/Blender2.5/RNA
* More ID property support. What was already possible was showing
ID properties as RNA properties. Now it is possible to define
RNA properties and have an ID property automatically created the
first time it is set (if not set it retuns the default).
* Added support for defining RNA structs and properties at runtime.
This is useful for python and plugins, and could also be used
for operators, not sure yet what is best there, they could be done
in preprocess for speed, but not sure how to do that while keeping
operator registration a single function.
* Added quick functions to get/set properties based on names, to be
used for operators.
* Added some simple support for inheritance, was already doing this
but having it as a feature simplifies things. Two things were added
for this: when defining a struct you can give a 'from' struct whose
properties will be copied, and structs like ID, operator, modifier,
can define a refine callback that will return the more specific type
of the struct like ID -> Object, Mesh, .. .
* Added simple windowmanager wrap with only the registered operators
list, used for testing RNA for operators.
* Added start of lamp wrapping (code by Michael Fox).
* Add back Object.data, was crashing with unknown data type.
* Added support for using consecutive variables like float r, g, b;
as an array without writing a manual get/set function.
* Also note the RNA documentation is updated now to be more
about how to define RNA and use it, including some diagrams.
http://wiki.blender.org/index.php/BlenderDev/Blender2.5/RNA
* Added support for ID properties, mapped as follows:
* IDP Int = RNA Int
* IDP Float, Double = RNA Float
* IDP_String = RNA String
* IDP Group = RNA IDPropertyGroup Struct
* IDP_Array = RNA Array
* PropertyRNA and StructRNA are now defined private for the module,
to force external code to always use accessor functions.
* Rename cname to identifier.
* Rename PropertyEnumItem to EnumPropertyItem.
* Wrapped min/max/step/precision, pointer type for RNA.
* Draw FLT_MAX a bit better in buttons.
* Added RNA list viewer. This is currently drawn in the outliner
window, the UI is limited but it is just intended to test RNA
at the moment.
* Added UI names for currently wrapped properties.
* Made iterating collections a bit more convenient.
* Added accessor functions for structs and properties instead of
direct access, in preparation of wrapping ID properties.
* Added more error prints for wrong defines.
* Wrap RNA data structures with RNA.
* Disable dependency code for now to avoid confusion.
size buffer if it's big enough, and otherwise allocate memory.
* Added BLI_dynstr_appendf() to construct strings easily in printf
style, this should make it easier to construct menu strings for
example.
* Added more error prints for wrong definitions, for cases that
would laters cause problems compiling or crash at runtime, and
also made messages more clear.
* Added some skeleton code for main/ID/mesh/vertex types for testing.
* Added support for automatic arrays as collections using SDNA.
* Changed how pointers to data work. Now they are always wrapped
in a PointerRNA struct, which contains the data pointer and type,
and also the data pointer and type of the ID datablock that this
belongs to, since for example a vertex on it's own may not have
enough information for some operations, it also needs the mesh.
* Added some code for defining dependencies with RNA, and looking up
data with paths like: scenes[0].objects["Cube"].data.verts[7].co.
Note sure either will end up being used, this is experimental.
http://wiki.blender.org/index.php/BlenderDev/Blender2.5/RNA
This is the first code for the Data API, also known as RNA system in the
2.5 Branch. It does not include a user interface, and only wraps some
Scene properties for testing. It is integrated with Scons and Makefiles,
and compiles a 'makesrna' program that generates an RNA.c file.
http://wiki.blender.org/index.php/BlenderDev/Blender2.5/DataAPIhttp://wiki.blender.org/index.php/BlenderDev/Blender2.5/RNA
The changes are quite local, basically adding a makesrna module which
works similar to the makesdna module. The one external change is in
moving genfile.c from blenloader to the makesdna module, so that it can
be reused by the RNA code. This also meant changing the DNA makefiles.
It seems to be doing dependencies correct still in my tests, but if
there is an issue with the DNA not being rebuilt this commit might be
the one causing it. Also it seems for scons the makesdna and makesrna
modules are compiling without warnings. Not a new issue but this should
be fixed.
The RNA code supports all types as defined in the Data API design, so
in that sense it is fairly complete and I hope that aspect will not
have to change much. Some obviously missing parts are context related
code, notify() functions for updates and user defined / ID properties.
