Overview

Package cmd is the front-end interface for the application as a command-line utility.

KeyStoreAuthenticator

KeyStoreAuthenticator prompts the user for their password, which is used to unlock their keystore file to interact with the Ethereum blockchain. Since multiple keystore files can exist at the configured directory, the KeyStoreAuthenticator will try the password on all keystore files present.

Client

Client is how the application is invoked from the command line. When you run the binary, for example `./chainlink n`, client.RunNode is called to start the Chainlink core. Similarly, running `./chainlink j` returns information on all jobs in the node, and `./chainlink s` with another argument as a JobID gives information specific to that job.

Renderer

Renderer helps format and display data (based on the kind of data it is) to the command line.
