-   Note: when passing in multiple targets their order is not important.
-   So for a fast build you can for e.g. run 'make lite ccache ninja'.
   Note: passing the argument 'BUILD_DIR=path' when calling make will override the default build dir.
   Note: passing the argument 'BUILD_CMAKE_ARGS=args' lets you add cmake arguments.

Julian Eisel	8c4f121492	Cleanup: Split header for Outliner tree building into C and C++ headers It's odd to include a C++ header (".hh") in C code, we should avoid that. All of the Outliner code should be moved to C++, I don't expect this C header to stay for long.	2020-11-09 13:54:30 +01:00
Julian Eisel	c796364f05	Cleanup: Rename Outliner "tree-view" types to "tree-display" & update comments "View" leads to weird names like `TreeViewViewLayer` and after all they are specific to what we call a "display mode", so "display" is more appropriate. Also add, update and correct comments.	2020-11-09 13:37:28 +01:00
Julian Eisel	4a572f06e9	Cleanup: Follow C++ code style for new Outliner building code * Use C++17 nested namespaces. * Use `_` suffix rather than prefix for private member variables. Also: Simplify code visually in `tree_view.cc` with `using namespace`.	2020-11-09 12:21:51 +01:00
Julian Eisel	fa91f90287	Cleanup: General cleanup of Outliner Blender File display mode building * Turn functions into member functions (makes API for a type more obvious & local, allows implicitly sharing data through member variables, enables order independend definition of functions, allows more natural language for function names because of the obvious context). * Prefer references over pointers for passing by reference (makes clear that NULL is not a valid value and that the current scope is not the owner). * Reduce indentation levels, use `continue` in loops to ensure preconditions are met. * Add asserts for sanity checks.	2020-11-09 00:37:41 +01:00
Julian Eisel	2d60f64960	UI Code Quality: Convert Outliner Blender File mode to new tree buiding design See https://developer.blender.org/D9499. Also: * Add `space_outliner/tree/common.cc` for functions shared between display modes. * Had to add a cast to `ListBaseWrapper` to make it work with ID lists. * Cleanup: Remove internal `Tree` alias for `ListBase`. That was more confusing than helpful.	2020-11-07 22:46:51 +01:00
Julian Eisel	fc6338d863	Cleanup: Put Outliner C++ namespace into `blender::ed` namespace, add comments Also remove unnecessary forward declaration.	2020-11-07 14:23:06 +01:00

Julian Eisel	126b6f8cc7	Cleanup: Comments & style improvements for new Outliner C++ code * Add comments to explain the design ideas better. * Follow code style guide for class layout. * Avoid uninitialized value after construction (general good practice).	2020-11-07 01:04:17 +01:00
Julian Eisel	86fe1ec968	UI Code Quality: Use C++ data-structures for Outliner object hierarchy building * Use `blender::Map` over `GHash` * Use `blender::Vector` over allocated `ListBase ` Benefits: Significantly reduces the amount of heap allocations in large trees (e.g. from O(n) to O(log(n)), where n is number of objects). * Higher type safety (no `void `, virtually no casts). More optimized (e.g. small buffer optimization). * More practicable, const-correct APIs with well-defined exception behavior. Code generally becomes more readable (less lines of code, less boilerplate, more logic-focused APIs because of greater language flexibility).	2020-11-07 00:15:09 +01:00
Julian Eisel	6f87489536	UI Code Quality: General refactor of Outliner View Layer display mode creation * Turn functions into member functions (makes API for a type more obvious & local, allows implicitly sharing data through member variables, enables order independend definition of functions, allows more natural language for function names because of the obvious context). * Move important variables to classes rather than passing around all the time (shorter, more task-focused code, localizes important data names). * Add helper class for adding object children sub-trees (smaller, more focused units are easier to reason about, have higher coherence, better testability, can manage own resources easily with RAII). * Use C++ iterators over C-macros (arguably more readable, less macros is generally preferred) * Add doxygen groups (visually emphasizes the coherence of code sections, provide place for higher level comments on sections). * Prefer references over pointers for passing by reference (makes clear that NULL is not a valid value and that the current scope is not the owner).	2020-11-06 22:55:36 +01:00
Julian Eisel	cf94571762	UI Code Quality: Start refactoring Outliner tree creation (using C++) The Outliner tree creation was very messy and hard to follow. Hardcoded display type checks are scattered over many places. This introduces a new abstraction "tree-view" to help constructing and managing the tree for the different display types (View Layer, Scene, Blender file, etc.). Idea is to have an abstract base class to define an interface (`AbstractTreeView`), and then subclasses with the implementation of each display type (e.g. `TreeViewViewLayer`, `TreeViewBlenderFile`, etc). The tree-viewer is kept alive until tree-rebuild as runtime data of the space, so that further queries based on the display type can be executed (e.g. "does the view support selection syncing?", "does it support restriction toggle columns?", etc.). I may still change the names a bit, not sure yet if "tree-view" is the right term for this helper.	2020-11-06 20:54:20 +01:00
