# Title: Render Partial Tag for Jekyll
|
|
# Author: Brandon Mathis http://brandonmathis.com
|
|
# Description: Import files on your filesystem into any blog post and render them inline.
|
|
# Note: Paths are relative to the source directory, if you import a file with yaml front matter, the yaml will be stripped out.
|
|
#
|
|
# Syntax {% render_partial path/to/file %}
|
|
#
|
|
# Example 1:
|
|
# {% render_partial about/_bio.markdown %}
|
|
#
|
|
# This will import source/about/_bio.markdown and render it inline.
|
|
# In this example I used an underscore at the beginning of the filename to prevent Jekyll
|
|
# from generating an about/bio.html (Jekyll doesn't convert files beginning with underscores)
|
|
#
|
|
# Example 2:
|
|
# {% render_partial ../README.markdown %}
|
|
#
|
|
# You can use relative pathnames, to include files outside of the source directory.
|
|
# This might be useful if you want to have a page for a project's README without having
|
|
# to duplicated the contents
|
|
#
|
|
