Dependencies

Dependency information is at this clickable badge:

Add the following to your ns declaration:

(:require [nomis-tailer.core :as tailer])

Tailing a Single File

Use tailer/make-single-file-tailer to create a single-file-tailer.

The tailing starts from the end of the file.

Use tailer/channel to get a core.async channel to take from. The values taken will be successive lines from the file.

Use tailer/close! to close a single-file-tailer.

Tailing Using a File Pattern

Use tailer/make-multi-file-tailer to create a multi-file-tailer.

Looks for the most recent file in dir that matches pattern and looks for new files every file-change-delay-ms.

The tailing starts from the end of any current file, and includes the full content of subsequent files.

Use tailer/channel and tailer/close! as for a single-file-tailer.
