Multiple outputs

Sometimes, we want to generate multiple configs from a single file. for this, we can use the .mpconf.

protoconf expects .mpconf's main() function to return a dict with a string as the key and a proto.Message as the value.

Example:

// file: src/myservice/myconfig.proto
syntax = "proto3";
message MyConfig {
  string name = 1;
  uint32 timeout = 2;
}

"""
file: ./src/myservice/outputs.mpconf
"""
load("myconfig.proto", "MyConfig")

out = {}

for i in range(5):
    out["config%d" % i] = MyConfig(name="config%d" % i, timeout=i * 3)

def main():
    return out

Now, when you compile your configs, you will see multiple outputs

$ protoconf compile .
