Welcome to Selinonlib’s documentation!¶

Selinonlib is a library and tool that is used in Selinon - a tool for dynamic data control flow on top of Celery distributed task queue. See Selinon documentation for more info. The project is hosted on GitHub.

Note

This documentation is for developers. If you want to get familiar with Selinon check Selinon documentation first.

Core Selinonlib¶

`selinonlib.builtin_predicate`	Built-in predicates used as core building blocks to build predicates.
`selinonlib.config`	User configuration.
`selinonlib.cache_config`	Configuration for caching.
`selinonlib.edge`	Edge representation in task/flow dependency graph.
`selinonlib.failure_node`	Failure node handling representation.
`selinonlib.failures`	Task and flow failure handling.
`selinonlib.flow`	A flow representation.
`selinonlib.global_config`	User’s global configuration section parsed from YAML config file.
`selinonlib.helpers`	Selinonlib library helpers.
`selinonlib.leaf_predicate`	Leaf predicate in condition - should always return True/False for the given input.
`selinonlib.node`	Abstract representation of nodes in task/flow dependencies - a node is either a task or a flow.
`selinonlib.predicate`	Predicate interface - predicate for building conditions.
`selinonlib.selective_run_function`	Function that is run on selective flow/task run.
`selinonlib.storage`	Storage configuration and abstraction from YAML config file.
