Service layer handles all REST API communications. restclient.py binds configuration with their HTTP Request requirements (headers, auth, etc.) and makes the call.
Config directory has API endpoint definitions. Create a new config to extend support, for example, Crowdin.
api_resources.py is the factory where API requests are grouped by operations. (fetch_project_details, fetch_translation_stats, etc.)
This acts as an API for service layer consumers.
Jobs are YML based. Tasks in YML are mapped to their respective (cmd) definitions in action_mapper.py.
System creates a linked list where each task represents a node. To extend, create new files in cmds directory and make an entry in action mapper.
Jobs runner acts as an interface between Jobs framework and CLI commands. It transforms command to their job execution state with required parameters.
Ideally JobRunner interface should be implemented for each CLI command.
CLI commands are based on CLICK framework. And they are all tied up with app_context in twcli/__init__.py.
See config.py to understand loading of user config.
