# Title: Include Code Tag for Jekyll
|
|
# Author: Brandon Mathis http://brandonmathis.com
|
|
# Description: Import files on your filesystem into any blog post as embedded code snippets with syntax highlighting and a download link.
|
|
# Configuration: You can set default import path in _config.yml (defaults to code_dir: downloads/code)
|
|
#
|
|
# Syntax {% include_code path/to/file %}
|
|
#
|
|
# Example 1:
|
|
# {% include_code javascripts/test.js %}
|
|
#
|
|
# This will import test.js from source/downloads/code/javascripts/test.js
|
|
# and output the contents in a syntax highlighted code block inside a figure,
|
|
# with a figcaption listing the file name and download link
|
|
#
|
|
# Example 2:
|
|
# You can also include an optional title for the <figcaption>
|
|
#
|
|
# {% include_code javascripts/test.js Example 2 %}
|
|
#
|
|
# will output a figcaption with the title: Example 2 (test.js)
|
|
#
