Skia Lua Bindings
Warning: The following has only been tested on Mac and Linux, but it will likely work for any Unix.
Prerequisites
This assumes you already have Skia building normally. If not, refer to How to build Skia.
Build
To build Lua support into Skia tools, set the GN argument skia_use_lua to true.
Optionally, set skia_use_system_lua. Then re-run GN.
Try It Out
The tools lua_app and lua_pictures should now be available when you compile,
and Viewer should now have a Lua sample.
To-Do
Skia had a feature that let it be imported as an .so by Lua. This feature is not yet supported by GN, but would have looked something like this:
$ lua
