# This script compiles and runs a skia app using Swiftshader in a docker container, making it easy
# to use Swiftshade w/o having to over-write /usr/local/lib/libEGL.so and related on the
# host development machine.
# The Skia repo to be compiled will be the one on the host machine, which will
# default to the one specified by the environment variable $SKIA_ROOT with a fallback to the
# current working directory.
# Example usage
# Prove SwiftShader is really being used:
# build-with-swift-shader-and-run "out/with-swift-shader/fuzz --gpuInfo -t api -n NativeGLCanvas"
# Notice the output says GL_RENDERER Google SwiftShader
# After running the above, feel free to check out $SKIA_OUT/out/with-swift-shader. It has binaries
# but if you try to run out/with-swift-shader/fuzz --gpuInfo -t api -n NativeGLCanvas w/o using
# Docker, it will use the host's GPU (e.g. GL_VENDOR NVIDIA Corporation).
# Reproduce a fuzzer bug in SwiftShader:
# First, copy the test case into $SKIA_ROOT, say $SKIA_ROOT/skbug_1234
# build-with-swift-shader-and-run "out/with-swift-shader/fuzz -t filter_fuzz -b /skia/skbug_1234"
# $SKIA_ROOT gets mapped to /skia - other than that, the docker container does not have
# access to the host file system.
