Modify rendered post output files

[sjordahl]

I'm using Nikola to render Jupyter Notebooks into blog posts. For most of my posts I do not want the notebook input fields in the output at all (may make this a metadata-driven task). I know I can hide them with CSS, but the data is still in the HTML and can add a lot of extra size to the page. I can easily make the modifications with python and I'm attempting to create my first plugin. The problem is that I get the following error:

ERROR: Two different tasks can't have a common target.'output/posts/jupyter-conversion-test/index.html' is a target for
fix_unclosed_tags:output/posts/jupyter-conversion-test/index.html and render_pages:output/posts/jupyter-conversion-test/index.html.

How can I add a task to the end of the build process to modify what the build process renders in an earlier step? I've attempted to use the Task class as well as the LateTask class and both produce the same error.

You can’t achieve what you want with tasks. I think the easiest solution would be to fix the HTML in the page as it is rendered. The template (post.tmpl or other) would call your_function(post.text()) — and your_function can be added to GLOBAL_CONTEXT in conf.py (no plugin needed).

To solve your particular problem, there might be a specific IPYNB_CONFIG that achieves exactly what you need.

Thank you, Kwpolska. Your response is very much appreciated! I'll give it a try.

Thanks again, Kwpolska. Your suggestion worked perfectly!
