Texlish: Better LaTeX

Texlish combines the best of LaTeX, Markdown, and indentation sensitivity to offer a clean, easy-to-read, easy-to-write syntax.

Texlish compiles to LaTeX, so it’s compatible with all existing packages, and you can submit to journals, arXiv, etc. as usual.

Texlish also aims to be 99% LaTeX compatible: you can write/import regular LaTeX, and gradually transition to Texlish’s cleaner syntax at your own pace.

Try Texlish for your next document, paper, or presentation!

Quickstart

# Install/update Texlish (assuming NodeJS is installed)
npm install -g texlish@latest
# Compile a .texlish file to PDF
texlish --pdf filename.texlish

If you want to use a different LaTeX engine than pdflatex, see the CLI documentation for more options.
