md2anki
Convert Markdown formatted documents to anki decks
The decks were tested on:
Features
-
Create an anki deck
.apkg
file -
The name of the deck and its notes will be updated on your next deck import (this works via automatic IDs, deletions can not be tracked!)
-
Very simple basic structure that supports additionally anki note tags and anki subdecks:
-
Supported question/answer content:
- LaTeX math (inline and blocks)
- Images (local files and URLs, vector and raster format)
- Code (inline and blocks)
- All basic Markdown features (i.e. tables, bold, italics, lines)
-
Merge notes from multiple markdown input files into a single deck output file
-
Export document and all used local assets to a custom directory that can easily be shared or used as backup
To evaluate code and export to pdf the following additional software needs to be installed:
# Linux (the apt package manager is just an example)
# > Evaluate code
sudo apt install clang inkscape latexmk nodejs texlive texlive-latex-extra #texlive-full
# > PDF export
sudo apt install librsvg2-bin pandoc texlive-xetex
# Windows (the choco package manager is just an example)
# > Evaluate code
choco install inkscape llvm miktex nodejs
# > PDF export
choco install miktex pandoc rsvg-convert
(On Windows rsvg-convert
can sometimes throw errors in combination with pandoc
but the latest build from miyako does not throw them so try this one if you get errors)
# Linux + Windows
npm install -g ts-node
# > For matplotlib python graphs (used in some examples):
python -m pip install numpy matplotlib
