An opinionated Markdown to Latex Converter

Warning: This Code is a total mess! I am sorry for that. But it has 100% test coverage so whenever someone introduces a new hack to get it working, we can be confident that nothing unexpectedly breaks.

All features were developed for compatibility with the modernthesis template.

How to use it

As a standalone converter

Install

# yarn 
yarn global add @adrianjost/md2tex
 
# or npm 
npm i -g @adrianjost/md2tex

Usage

md2tex "pathToSrcMdFile" "pathToTargetTexFile"

• The pathToSrcMdFile default to ./in.md.
• The pathToTargetTexFile default to ./out.tex.

If you provide a directory path instead of a file for both paths, all .md files will get converted to the output directory. The Filestructure will remain the same.

As a regular dependency

Install

# yarn 
yarn add -D @adrianjost/md2tex
 
# or npm 
npm i -D @adrianjost/md2tex

Usage

import md2tex from "@adrianjost/md2tex";
// or
// const { convert: md2tex } = require("@adrianjost/md2tex")
 
const md = `# Hello World`;
const tex = md2tex(md);
console.log(tex);

Features

You can use a codeblock with the language latex to write latex code directly in your markdown files. This Code is getting directly copied into the output without any further conversion.
