Logger Python Plugin

The Logger plugin implements the logger-interface from the ens/wraps.eth:logger@1.0.0 package (see ./src/schema.graphql). By default, it logs all events using the Python logging module. You can customize this behavior by setting the Logger property on the plugin's configuration object (examples below).

Usage

1. Configure Client

When creating your Polywrap Python client, add the logger plugin:

from polywrap_client_config_builder  import PolywrapClientConfigBuilder
from polywrap_logger_plugin import logger_plugin
from polywrap_client import PolywrapClient

config = PolywrapClientConfigBuilder().set_package(
    uri=Uri.from_str("plugin/logger"),
    package=logger_plugin()
).set_interface(
    interface=Uri.from_str("ens/wraps.eth:logger@1.0.0"),
    implementations=[Uri.from_str("plugin/logger")]
).set_redirect(
    Uri.from_str("ens/wraps.eth:logger@1.0.0"),
    Uri.from_str("plugin/logger")
).build()
client = PolywrapClient(config)

2. Invoke The Logger

Invocations to the logger plugin can be made via the interface URI (which will get redirected), or the plugin's URI directly:

await client.invoke({
  'uri': 'ens/wraps.eth:logger@1.0.0' | 'plugin/logger',
  'method': 'log',
  'args': {
    'level': 'INFO',
    'message': 'foo bar baz'
  }
})

3. Customize The Logger

When adding the logger to your client, you can add your own custom log function:

config = PolywrapClientConfigBuilder().set_package(
    uri=Uri.from_str("plugin/logger"),
    package=logger_plugin(LoggerConfig(logger=YourLogger(), level=LogLevel.INFO))
).set_interface(
    interface=Uri.from_str("ens/wraps.eth:logger@1.0.0"),
    implementations=[Uri.from_str("plugin/logger")]
).set_redirect(
    Uri.from_str("ens/wraps.eth:logger@1.0.0"),
    Uri.from_str("plugin/logger")
).build()

4. Add Multiple Loggers

Multiple logger implementations can be added to the client:

config = PolywrapClientConfigBuilder().set_package(
    uri=Uri.from_str("plugin/logger"),
    package=logger_plugin(LoggerConfig(logger=YourLogger(), level=LogLevel.INFO))
).set_interface(
    interface=Uri.from_str("ens/wraps.eth:logger@1.0.0"),
    implementations=[Uri.from_str("plugin/logger"), Uri.from_str("plugin/custom-logger")]
).set_package(
    uri=Uri.from_str("plugin/custom-logger"),
    package=custom_logger_plugin()
).build()

5. Invoke All Logger Implementations

When you'd like to log something to more than one logger, you can invoke all implementations of the logger interface:

implementations = client.get_implementations('ens/wraps.eth:logger@1.0.0')

for impl in implementations:
    await client.invoke({
        'uri': impl,
        'method': 'log',
        'args': {
            'level': 'INFO',
            'message': 'message'
        }
    })
