{# ------------------------------------------------------------------------ #}
{# Creative Commons license mark generator for Jinja2 templates, including #}
{# Pelican-generated static sites (or blogs). #}
{# ------------------------------------------------------------------------ #}
{# To use, put this file in a location where your template can import it. #}
{# Then import into the template, for example like this: #}
{# {% from '/path/to/where/you/placed/the/file' import cc_license_mark %} #}
{# Then call as simply as {{ cc_license_mark("CC-BY") }}. #}
{# #}
{# If full attribution markup is desired in a Pelican template, the #}
{# attr_props dict can be defaulted to the following when calling the macro:#}
{# attr_props={'title':SITENAME,'name':AUTHOR,'url':SITEURL}

{# Generate a license mark for Creative Commons licensed content. #}
{# Choose the license either by name (CC-BY, CC-BY-SA, CC-BY-NC-SA, or #}
{# CC-BY-NC-ND), or by its features (allow derivatives: Yes, No, ShareAlike;#}
{# allow commercial reuse: Yes, No). Name, if provided, takes precedence, #}
{# and case is ignored. #}
{# #}
{# Optional: #}
{# br_after_icon: if true put a line break after the license icon #}
{# attr_markup: if true create markup for fulll attribution #}
{# attr_props: if attr_markup, a dict with title, name, and url keys #}
{# specifying how under which title, to which creator, and #}
