I have a love-hate relationship with LaTeX... in 2016, I wrote my PhD with it, for wich I defined lots of helpers and commands.I used xetex for some obscure reasons I don't remember.The final result was beautiful but I dread opening any of those files. And it doesnt compile anymore.

Among all the systems (tools, languages, devices...) I exploited professinaly, LaTeX is the one that remains the most obscure and frustrating to me. I'm not sure why.
