markdown-environments 1.10.2

Highly customizable extensions for Python-Markdown in the style of LaTeX environments/theorems

Python-Markdown Environments

Replicating amsthm features and syntax in Markdown so you can publish mathematical papers in HTML—because what mathematician hasn't tried to publish in the very reputable journal called Their Janky Flask Personal Site That No One Will Ever See?

This Python-Markdown extension uses LaTeX-like syntax

\begin{...}
...
\end{...}

to create environments such as captioned figures, general-purpose <div>s, dropdowns, and user-defined LaTeX-style theorems that can be styled with attached HTML classes.

Installation

pip install markdown-environments

Available Environments

• \begin{captioned_figure}: figures with captions
• \begin{cited_blockquote}: blockquotes with quote attribution
• User-defined environments wrapped in general-purpose <div>s to style to your heart's content
• User-defined environments formatted as <details> and <summary> dropdowns
• User-defined LaTeX theorem environments with customizable:
  • Theorem counters
  • Heading punctuation
  • Linkable ids by theorem name

Example Usage

Backend:

import markdown
from markdown_environments import ThmsExtension

input_text = ...
output_text = markdown.markdown(input_text, extensions=[
    ThmsExtension(
        div_config={
            "types": {
                "thm": {
                    "thm_type": "Theorem",
                    "html_class": "md-thm",
                    "thm_counter_incr": "0,0,1"
                },
                r"thm\\\*": {
                    "thm_type": "Theorem",

                    "thm_type": "Exercise",
                    "html_class": "md-exer",
                    "thm_counter_incr": "0,0,1"
                },
                "pf": {
                    "thm_type": "Proof",
                    "thm_counter_incr": "0,0,0,1",
                    "thm_name_overrides_thm_heading": True
                }
            },
            "html_class": "md-dropdown",
            "summary_html_class": "md-dropdown__summary mb-0"
        },
        thm_heading_config={
            "html_class": "md-thm-heading",
            "emph_html_class": "md-thm-heading__emph"
        }
    )
])

Markdown input:

# Section {{1}}: this is theorem counter syntax from ThmsExtension()

## Subsection {{0,1}}: Bees

Here we begin our study of bees.



\begin{thm}[the bee theorem]
According to all known laws of aviation, there is no way that a bee should be able to fly.
\end{thm}

\begin{pf}
Its wings are too small to get its fat little body off the ground.
\end{pf}



\begin{thm\*}{hidden thm name used as `id`; not real LaTeX syntax}
Bees, of course, fly anyways.
\end{thm\*}

\begin{pf}[Proofs are configured to have titles override the heading]{hidden names are useless when there's already a name}
Because bees don't care what humans think is impossible.
\end{pf}



\begin{exer}

\begin{summary}
Prove that this `summary` environment is common to all dropdown-based environments.
\end{summary}

Solution: by reading the documentation, of course!
\end{exer}



\begin{exer}
All dropdowns initialized in `ThmsExtension()` have a default `summary` value of `thm_type`,
so using dropdowns like `pf` and `exer` here without a `summary` block is also fine.
\end{exer}

HTML output (prettified):
