PyLaTeX

Latex is very easy to generate from any programming language, because it's just text. I created a Python package for it with an easy and extensible API: https://github.com/JelteF/PyLaTeX If you want to create something similar, be sure to escape untrusted input though. With an escape function similar to the one in my library. Otherwise it's very easy for an attacker to execute arbitrary commands.

Luckily I haven't had the need to create pdfs yet now that I'm using Go. However, if I would, I would generate LaTeX instead of PDFs directly. I did the same in Python a and it has turned out great: https://github.com/JelteF/PyLaTeX The API can be made much more high level, because of all functionality and packages LaTeX has. The most important thing is to have a good escape function that is used by default for all text, otherwise it's very easy to execute arbitrary shell commands for an attacker. If anyone wants to create a Go package similar to mine, feel free to contact me if you want any more advice (email in github profile).

PyLaTeX does that: with doc.create(Section('A section')): doc.append('Some regular text and some ') doc.append(italic('italic text. ')) https://github.com/JelteF/PyLaTeX
