Usage

As Event/Logging Language

E.g. it might be used for a server log:

2015-09-12 09:24:13:
	user: John Doe
	action: "mkdir test"
2015-09-12 09:24:13:
	user: Thomas Doe
	action: "cd /var/www"
2015-09-12 09:24:13:
	user: John Doe
	action: "touch test/a.txt"

As Delta Encoding

EventLang can also be use as a delta encoding for YAML files. E.g. it could be used as a storage format for to-dos in a to-do manager while keeping their history.

2015-08-03 15:46:
	title: Buy milk
2015-08-04 10:12:
	title: Buy 3 bottles of milk
2015-08-05 08:33:
	priority: high
2015-08-06 22:51:
	completed: true

Compiled to a YAML file this would yield:

title: Buy 3 bottles of milk
priority: high
completed: true
