The wolfdown.sh
script converts a Wolfram Language notebook to a Jekyll markdown file.
Clone this repo:
[rule146@rule146: code]$ git clone git@github.com:paul-jean/wolfdown.git
Open one of the example notebooks using Mathematica to see how it looks:
Copy the example-blog
directory, which contains a working jekyll site layout:
[rule146@rule146: wolfdown]$ cp -R example-blog export-test
[rule146@rule146: wolfdown]$ lt export-test/

drwxr-xr-x 7 rule146 staff 238B Feb 12 00:24 _posts/
Now export one of the example notebooks in the example-notebooks
directory (note the script requires full paths to be given for the notebook file and the jekyll directory). Call the wolfdown.sh
script with the path to the Wolfram Language notebook
file, the path to the Jekyll site, and (optionally) the width of the images to
generate in pixels:
[rule146@rule146: wolfdown]$ ./wolfdown.sh /Users/rule146/code/wolfdown/example-notebooks/eg-notebook.nb /Users/rule146/code/wolfdown/export-test/ 500
/Users/rule146/code/wolfdown/export-test/_posts/2017-02-12-eg-notebook.md
The script returns the full path to the generated markdown file, in the
_posts
directory of the Jekyll layout.
The script puts any image assets from the notebook
conversion into the Jekyll layout under an assets
directory:
[rule146@rule146: wolfdown]$ tree export-test/assets/

It should hopefully look like a reasonable rendition of the notebook.
wolfdown.sh nb_file jekyll_dir [device_width] [post_title]
Call the script with:
Run wolfdown.sh
with no args to see the script usage message:

So far this has only been tested on OS X 10.11 (El Capitan), using Wolfram Language 11.0.1 for Mac OS X x86 (64-bit).
