+Convenience Targets
   Provided for building Blender, (multiple at once can be used).

   * debug:         Build a debug binary.
   * full:          Enable all supported dependencies & options.
   * lite:          Disable non essential features for a smaller binary and faster build.
-   * release:       Complete build with all options enabled including CUDA and Optix, matching the releases on blender.org
+   * release        Complete build with all options enabled including CUDA and Optix, matching the releases on blender.org
   * headless:      Build without an interface (renderfarm or server automation).
   * cycles:        Build Cycles standalone only, without Blender.
   * bpy:           Build as a python module which can be loaded from python directly.
+   * deps:          Build library dependencies (intended only for platform maintainers).
+
   * developer:     Enable faster builds, error checking and tests, recommended for developers.
+   * config:        Run cmake configuration tool to set build options.
   * ninja:         Use ninja build tool for faster builds.
-   * ccache:        Use ccache for faster rebuilds.

   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.

-Other Convenience Targets

-   * deps:          Build library dependencies (intended only for platform maintainers).
-
-                    The existance of locally build dependancies overrides the pre-built dependencies from subversion.
-                    These must be manually removed from '../lib/' to go back to using the pre-compiled libraries.

 Project Files

The space and necessary context is duplicated, then the context is switched and that tab is searched. However, this is still pretty buggy and the enum isn't drawing correctly. I'm probably not filling the bitfield correctly. Mainly committing this to get it out there and focus on smaller fixes / improvements to it.	2020-07-09 16:25:20 -04:00
Hans Goudey	169ac2805e	Property Search: Add search filter active tabs property I also generalized the tab "adding" code in RNA to make it usable for filling both the context enum and the active search filter tabs properties. The tab layout code might need to be extended to add the idea of a custom highlight property.	2020-07-09 08:45:54 -04:00

Hans Goudey	136475dca3	Property Search: Refactor to simpler method This method doesn't try to change the input layouts at all.

Hans Goudey	170a40c338	Property Search: Sort filtered panels properly Instead of just putting the filtered panels at the bottom, or not updating their search order, we stop increasing the offset while the current panel is invisible.

Hans Goudey	712ccc2602	Property Search: Improve interaction with panels This isn't perfect yet, but the animation is back, and it works much better. There are still two issues though: 1. Order doesn't update sometimes while searching / ending search. 2. Panels are still displayed when empty in some situations. The solution is probably just adding some more special cases. Possibly a tag for panel aligning when the search filter is changed to force special ordering calculations.	2020-06-17 13:14:58 -04:00

Hans Goudey	a34c25046b	Property Search: Refactor / simplify, and better layout The single column layout works much better now, as most of the code that dealt with trying to remove empty layouts has been rewritten. The search filter code is not a completely separate pass for the sake of simplicity. Also, toggle buttons have their text replaced with the rna property name. There branch is far from stable, and there's a tricky memory leak still to track down as well.	2020-06-12 21:59:07 -04:00

Hans Goudey	db76f34ed6	UI: Start towards property search in public branch This is VERY WIP, but I will continue work in this branch. Implementation starts with a few things: - A pass at the end of the layout system to scan buttons based on a search string set by the properties space. Buttons which don't fit the filter are removed from the layouts. - A pass after the filter to move buttons that are still in layouts to a single column "search layout." There is currently a bug with this that adds too much space in between items. - An attempt to only show panels that haven't been completely filtered by the previous two steps. This is quite buggy right now: panels don't animate properly and sometimes it fails. - An attempt at a keymap item "ctrl-F" to activate the search button. "alt-F" should probably clear the button too.	2020-06-11 18:07:24 -04:00
