Structuring your code

Sometimes, when we use protoconf we will want to write helpers functions and global constants that we might want to include in multiple configs. We can define those in .pinc files.

.pinc files are starlark code which doesn't produce configs (doesn't evaluate the main() function).

Example:

"""
file: ./src/helpers.pinc
"""
PROTOCONF_VERSION="0.1.3"

def format_name(person):
    # assumes `person` is a proto message that have `first_name` and `last_name`
    return "%s %s" % (person.first_name, person.last_name)

We can now load the variables and functions in this file to another starlark file (pinc, .pconf or .mpconf)

load("//helpers.pinc", "PROTOCONF_VERSION", "format_name")
