Markdown Equations Fixer and Converter

A command-line tool to standardize mathematical equations in Markdown files and convert documents between formats (Markdown, LaTeX, DOCX, PDF).

Key Features

• Fix Markdown Equations: Standardizes LaTeX-style equations to Markdown format
  • \[...\] → $$...$$ (block equations)
  • \(...\) → $...$ (inline equations)
  • Multi-line equations supported
• Document Conversion: Convert between formats using Pandoc
  • Input: markdown, gfm, commonmark, latex, org, docx
  • Output: markdown, gfm, commonmark, latex, org, docx, pdf
• CLI Features: Recursive processing, dry-run mode, progress indicators

Installation

Prerequisites: Python 3.7+

pip install markdown-equations-fixer

For document conversion, install Pandoc:

• Windows: choco install pandoc
• macOS: brew install pandoc
• Linux: sudo apt-get install pandoc

For PDF/DOCX output, install a LaTeX distribution:

• Windows: choco install miktex
• macOS: brew install --cask basictex
• Linux: sudo apt-get install texlive-latex-extra

Usage

Fix Equations

Standardize mathematical equations in Markdown files (.md, .markdown):

# Fix a single file
meq-fixer fix document.md

# Fix multiple files/directories
meq-fixer fix file1.md file2.md ./docs/

# Recursively process a directory
meq-fixer fix -r ./my-project/

# Preview changes without modifying (dry run)
meq-fixer fix --dry-run thesis.md

# Verbose output
meq-fixer fix -v document.md

Options:

• --dry-run: Preview without making changes
• --verbose, -v: Show detailed progress
• --recursive, -r: Process subdirectories

Convert Documents

Convert between document formats:

# Markdown to DOCX
meq-fixer convert paper.md paper.docx --to-format docx

# LaTeX to GitHub Markdown
meq-fixer convert report.tex report.md -f latex -t gfm

# Convert and fix equations (Markdown output only)
meq-fixer convert paper.tex paper.md -t markdown --fix-equations

# Markdown to PDF
meq-fixer convert thesis.md thesis.pdf -t pdf

Options:

• --from-format, -f: Input format (markdown, gfm, commonmark, latex, org, docx)
• --to-format, -t: Output format (markdown, gfm, commonmark, latex, pdf, docx, org)
• --fix-equations: Fix equations in Markdown output (Markdown formats only)

Examples

Input:

Here's an equation: \[E = mc^2\]

And a matrix:
\[
\begin{bmatrix}
1 & 2 & 3 \\
4 & 5 & 6
\end{bmatrix}
\]

Output: May not format properly on github, but will work on markdown editor apps like obsidian, marktext, etc.

Here's an equation: $$E = mc^2$$

And a matrix:
$$
\begin{bmatrix}
1 & 2 & 3 \\
4 & 5 & 6
\end{bmatrix}
