Current evaluation

Feature request to support architecture-conditional (on/else) syntax in the apps environment key, currently limited to stage-packages. Open since 2019 with no comments or maintainer response; grammar support has since expanded to more part keywords but app environment remains unaddressed.

Suggested action: needs triage

Reason: The issue is a well-scoped feature request (grammar/on-else for app environment variables) with zero comments, no labels beyond topic tags, and no maintainer interaction in ~8.5 years, so it has never been triaged. Grammar support has since been extended to more part keywords (e.g. build-environment, build-snaps) per commit history, but the apps.environment key is not in the grammar-processed keys list (snapcraft/parts/grammar.py _KEYS), so the request remains unimplemented and worth a maintainer decision.

Issue body

I'm doing raspberry pi development and use an environment variable to enable/disable a hardware simulator. When the snap is being deployed into a test (non-arm64) environment I need to set a number of environment variables to enable the simulator and disable the loading of the .so file (the application is java but the hardware interface is in a .so). I came across the 'on' 'else' keywords and they look perfect for this sort of problem. I want to be able to write: apps:     pi-gation:       command: tomcat-launch       daemon: simple       plugs: [network, network-bind]       environment:       on arm64:             PI4J_PLATFORM : RaspberryPi GPIO Provider        else:           PI4J_PLATFORM : Simulated           SimulatedPlatform : RaspberryPi GPIO Provider Currently the on..else keywords are only supported for the 'stage-packages' key word. on..else should be supported for setting environment variables. Possibly the concept should be considered for a number of other properties.
