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.

This is a fork of @adrianjost/md2tex to allow images from remote urls to be fetched as well. Make sure to enable write18 and import the necessary latex packages (graphicx, float)

All features were developed for compatibility with the modernthesis template.

How to use it

As a standalone converter

Install

# yarn
yarn global add @manyaagarwal/md2tex

# or npm
npm i -g @manyaagarwal/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 @manyaagarwal/md2tex

# or npm
npm i -D @manyaagarwal/md2tex

Usage

import md2tex from "@manyaagarwal/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.

• It is also not possible to use inline styles in headlines like # _italic_ headline
• Not all characters get escaped correctly. It's not working inside headlines and normal text without any formatting.
