Provide a configuration option for the location of the function

[andrew-su]

Feature Request

A way to specify the location of a function within a directory. This is relevant to a monorepo consisting of multiple functions, possibly with multiple directories that could contain your function(s).

This could be something like BP_FUNCTION_SEARCH_PATH or BP_FUNCTION_PATH. We can discuss on what name is appropriate in the comments.

Describe alternatives you've considered

New repo per function and everything is top-level. Applications may have multiple moving parts that are closely related.

⚠️ Still in an early discovery phase

PB_FUNCTION_PATH seems acceptable to me.

nvm: They're separate work. This one relates to the situation where your functions are in different folders possible, so more of a directory level. The prior committed BP_FUNCTION just identifies the name of your singular default function.
