* Any Struct can now have ID properties, by creating a callback
function to create/return an IDProperty.
* Wrapped PoseChannel ID properties.
* Note there is still no way to create ID Properties in 2.5, though
the callback to get/create the initial group is now exposed through
RNA_struct_idproperties.
The Python API to define Panels and Operators is based on subclassing,
this makes that system more generic, and based on RNA. Hopefully that
will make it easy to make various parts of Blender more extensible.
* The system simply uses RNA properties and functions and marks them
with REGISTER to make them part of the type registration process.
Additionally, the struct must provide a register/unregister callback
to create/free the PanelType or similar.
* From the python side there were some small changes, mainly that
registration now goes trough bpy.types.register instead of
bpy.ui.addPanel.
* Only Panels have been wrapped this way now. Check rna_ui.c to see
how this code works. There's still some rough edges and possibilities
to make it cleaner, though it works without any manual python code.
* Started some docs here:
http://wiki.blender.org/index.php/BlenderDev/Blender2.5/RNATypeRegistration
* Also changed some RNA_property and RNA_struct functions to not
require a PointerRNA anymore, where they were not required (which
is actually the cause of most changed files).
which can be defined to call C functions with defined parameters.
* Parameters are RNA properties, with the same types.
* Parameters are stored in a ParameterList, which is like a small
stack with the values. This is then used to call the C function.
* Includes Python integration.
* Only one test function is part of this commit, ID.rename.
* Integration with the editors/ module is not included in this
commit, there's some issues to be worked out for that still.
* Allow pointers to be editable, did SpaceTextEditor.text as a test.
* Changed PROP_NOT_EDITABLE to PROP_EDITABLE, and added
RNA_def_property_clear_flag.
* Removed rna_dependency.c test code.
* Made it based on string lookups rather than fixed enum, to make
it extensible by python scripts.
* Context callbacks now also have to specify RNA type when returning
pointers or collections. For non-RNA wrapped data, UnknownType can
be used.
* RNA wrapped context. The WM entries are fixed, for data context
only main and scene are defined properties. Other data entries have
to be dynamically looked up.
* I've added some special code in python for the dynamic context
lookups. Tried to hide it behind RNA but didn't find a clean way to
do it yet. Still unused/untested.
* Also minor fix for warning about propertional edit property in
transform code, and fix for usage of operator poll with checking if
it was NULL.
* Added Particle wrapping patch by Roelf de Kock. It's not
complete yet and I haven't reviewed it, but committing anyway,
will get to it later.
* Added "Percentage" subtype for floats. Doesn't really do
much besides making auto rna buttons into sliders rather than
numeric inputs, but can later display in % rather than 0.0-1.0.
* 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
* 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.
This is used for generating docs so a nested RNA struct such as MaterialRaytraceTransparency are listed under Material rather then in the global struct list)
These RNA structs are used for grouping properties and don't correspond to a C structure.
* 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).
* rna_validate_identifier now checks identifiers are not python keywords such as if, and, from (builtins like max, object and sort are ok)
* rna_validate_identifier prints an error explaining why it fails
* renamed Struct's "from" to "base" - to point to the struct inherited from.
* renamed ImageUsers's "pass" and "layer" to "renderPass" and "renderLayer"
* use the identifier as the key for ENUM's (matching structs and properties)
bpydoc.structs.keys() - ['Actuator', 'ActuatorSensor', 'AlwaysSensor', 'AndController'.... etc
now reads...
bpydoc.structs.keys() - ['Actuator', 'Actuator Sensor', 'Always Sensor', 'And Controller'...
This is more correct since an identifier is supposted to be unique when a name might not be.
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);
* 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.
* 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.
