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).
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

> require 'skia'
> paint = Sk.newPaint()
> paint:setColor{a=1, r=1, g=0, b=0}
> doc = Sk.newDocumentPDF('test.pdf')
> canvas = doc:beginPage(72*8.5, 72*11)
> canvas:drawText('Hello Lua', 300, 300, paint)
> doc:close()
