# Overview
|
|
`execlog` is a lightweight multi-threaded job framework written in Python. It implements a
|
|
simple event-based model over core Python utilities like `ThreadPoolExecutor` to
|
|
facilitate reactivity and manage concurrent responses.
|
|
|
|
There are a few top-level classes exposed by the package:
|
|
|
|
- **Router**: Central event routing object. Routers facilitate route registration,
|
|
allowing for _pattern_-based matching of _events_ to arbitrary _callback_ functions. For
|
|
example, you could have a function that converts a PDF file to a collection images
|
|
(_callback_), and want this function to be called for a new files (_event_) that match
|
|
the glob `*.pdf` (_pattern_).
|
|
- **Listener**: Connective event listening object, often created directly by router
|
|
instances. Listeners pay attention to events arising along registered routes of an
|
|
affiliated router, passing them through (after optional delays, debouncing, filtering,
|
|
etc). In the above example, the associated `Listener` instance might wrap a tool like
|
|
iNotify to dynamically respond to file events.
|
|
- **Server**: Long-running process manager for listeners and optional live-reloading via
|
|
HTTP. Interfaces with listener `start()` and `shutdown()` for graceful interruption.
