Autodocument vars/features
MatthewCroughan opened this issue · comments
When making additional envvars that control the program/code flow like cac2be7 it is important to consider that it is not automatically documenting itself or making itself known in anyway.
It might be possible to make a rust function that mandates a documentation string, and that could be printed in some way by the program, imagine stardust-xr-server --list-vars
. The way --list-vars
could be populated is by a function like stardustxr_make_feature
which would take a documentation string and env var as arguments, therefore making it impossible to make an envvar lookup that doesn't document itself and make itself known within the code.
Should a config
struct be introduced that is build from cli args
, env vars
and config files
to solve this?
This struct could easily be (self-) documented and extended. It would also encapsulate all configuration.
