This is a simple org export engine for Jekyll Markdown. It is built from the fabulous code provided by @yoshinari-nomura/org-octopress.
Unlike the original code (and indeed most org-jekyll exporters) this exporter is built on top of ox-md to generate markdown.
More details on the development of this exporter can be found on my blog.
The exporting of the #+DATE property (into the YAML front matter) is controlled by the date: option.
Today’s date can be prepended to the filename with the option org-jekyll-use-todays-date.
Table export is now implemented (rather than falling through to HTML export). Valid kramdown tables are created, but they do not look pretty and cell widths are not even. Org-table alignments are not currently implemented.
