# Title: Include Array Tag for Jekyll
|
||
|
|
# Author: Jason Woodward http://www.woodwardjd.com
|
||
|
|
# Description: Import files on your filesystem as specified in a configuration variable in _config.yml. Mostly cribbed from Jekyll's include tag.
|
||
|
|
# Syntax: {% include_array variable_name_from_config.yml %}
|
||
|
|
#
|
||
|
|
# Example 1:
|
||
|
|
# {% include_array asides %}
|
||
|
|
#
|
||
|
|
# _config.yml snippet:
|
||
|
|
# asides: [asides/twitter.html, asides/custom/my_picture.html]
|
||
|
|
#
