Use of jinja2 to create PDFs of tear sheets

[trical09]

Has jinja ever been considered for creating PDF versions of the tear sheets? I use tear sheets as reports that I can then save to file as records. I can distribute them, print them out, and reference them later. This ability to use a tear sheet as a document is really valuable to me. I know that pyfolio features the ability to produce a tear sheet as a matplotlib fig or as a part of a Jupyter notebook, which can then be turned into a PDF. It seems like the most straightforward way to make a tear sheet that one could automatically generate and store as a report would be to create a report specifically designed to be viewed in a standard US Letter or A4 format.

One can do this using jinja2 and an HTML to PDF library such as weasyprint. The process involves:

• Creating an HTML template for the report. This is mostly just headers and places for figures or data tables
• Creating a CSS formatting file for the report
• Generating the report content (figures and tables)
• Converting the matplotlib figs to SVG and then encoding them in base64 (this is a way to inject the image into the HTML itself that is then automatically rendered at high quality
• Converting pandas DataFrames of data tables to HTML
• Creating a big string representation of the report in HTML by using jinja2 to inject the image, table strings, and CSS styling into the template
• Rendering the HTML string as a PDF
• Saving the PDF to file

Thoughts / interest?

Is there any way to get the pyfolio output as HTML currently?

I believe the only way to do this at this time would be to somehow convert a matplotlib fig to an image with an HTML wrapper file. There may be a utility to do this.
