pgserviceparser

A python package parsing the PostgreSQL connection service file.

>>> import pgserviceparser

Finding the PostgreSQL connection service file with conf_path

Returns the path found for the pg_service.conf on the system as string.

>>> pgserviceparser.conf_path()
'/home/dave/.pg_service.conf'

Listing all the services with service_names

Returns all service names in a list. Optionally you can pass a config file path. Otherwise it gets it by conf_path.

>>> pgserviceparser.service_names()
['srvce_wandplaene', 'ktn_solothurn', 'daves_bakery']

Receiving the configuration for a service with service_config

Returns the config from the given service name as a dict. Optionally you can pass a config file path. Otherwise it gets it by conf_path.

>>> pgserviceparser.service_config('daves_bakery')
{'host': 'localhost', 'port': '5432', 'dbname': 'bakery', 'user': 'dave', 'password': 'fischersfritz'}

Getting the full configuration with full_config

Returns full pgservice config as configparser.ConfigParser(). Optionally you can pass a config file path. Otherwise it gets it by conf_path.

>>> pgserviceparser.full_config()
<configparser.ConfigParser object at 0x7f4c6d66b580>

Add a new service or remove one

Add a new service:

import pgserviceparser
new_srv_settings = {"host": "localhost", "dbname": "best_database_ever", "port": 5432, "user": "ro_gis_user"}
new_srv = pgserviceparser.write_service(service_name="gis_prod_ro", settings=new_srv_settings, create_if_not_found=True)
assert isinstance(new_srv, dict)

The PG service file has now:

[gis_prod_ro]
host=localhost
dbname=best_database_ever
port=5432
user=ro_gis_user

To remove it:

pgserviceparser.remove_service("gis_prod_ro")
