jekyll-geo-pattern's Introduction

Geo Pattern Plugin

A liquid tag for Jekyll to generate an SVG/Base64 geo pattern. Based on https://github.com/jasonlong/geo_pattern.

Setting up

Add the following to your site's _config.yml file

gems:
  - jekyll-geo-pattern

Usage

You can choose to generate either a Base64 encoded string:

{% base64_geo_pattern text="Mastering Markdown" %}

Or, an SVG image:

{% svg_geo_pattern text="Mastering Markdown"} %}

Note that you provide parameter as regular attribues. You must have at least the text key. The geopattern is generated from this text.

You can also pass in the other options from the geo_pattern library:

{% base64_geo_pattern text"Some title" base_color="#fc0"} %}
{% svg_geo_pattern text="Another title" generator="sine_waves"} %}

With the Base64 pattern, you can generate something like this as a visual element:

<div style="background-image: url(data:image/svg+xml;base64,{% base64_geo_pattern text="Mastering Markdown" %});"></div>

Specifying base colors with all integers causes errors

@gjtorikian I found that when specifying a base_color that was all integers (#246642) while alphanumeric (#ab6642) works fine. I initially thought this was a problem in geo_pattern itself, but it seems to work fine there.

Here is an example:

{% base64_geo_pattern text=page.title base_color="#963636" %}

The error is coming from the color gem being used by geo_pattern. It looks like it thinks the color is a Fixnum and not a String.

Liquid Exception: undefined method `scan' for 963636:Fixnum in _layouts/article.html
[Listen warning]: Change block raise an execption: undefined method `scan' for 963636:Fixnum
