The playground, the notebook cells, the source editor with its marks, the inspector columns and the canvas are written once for both Apple platforms, with a file naming what the two frameworks call differently. The editor is where they really part company. The engine owns the image and its start-up, so a mission reaches the whole of Pharo.

# Builds glslang and SPIRV-Cross into Vendor/shader-toolchain, which is what
|
|
# the runtime GLSL->MSL translation links against. Neither project builds
|
|
# under SwiftPM, and relying on whatever a machine happens to have installed
|
|
# means the build works here and nowhere else.
|
|
#
|
|
# One tree per slice, because the runtime translation ships wherever the app
|
|
# does: macOS, the device and the simulator. Only the desktop slice carries
|
|
# the binaries, which are what the build-time translation runs.
|
|
#
|
|
# Only Apple platforms need this: elsewhere OpenGL takes the GLSL as it stands.
