Feature request: arduino-cli compile --show-properties option to show fully expanded properties #1046
Description
When using arduino-cli as part of a larger build system, I often need to fetch build properties for a sketch at build or flash time.
arduino-cli compile --show-properties will give me a dump of all the properties I might possibly want, but it dumps them as non-expanded templates.
For example, the default avr compiler.path gets dumped as:
compiler.path={runtime.tools.avr-gcc.path}/bin/
I would find it hugely valuable to have an option to --show-properties that shows the properties after template substitution.
