I am in the initial stages of writing my thesis (Maths). I once wrote a joint paper with someone and because they had an existing template we used it, with all the latex macros it had. Basically there were so many macros that I would have to repeatedly go, look and find the macro for the symbols. When I programme (c, python) I just give the variables full names, instead of calling a variable r, or rem, I just use the full word remainder for example. I just need someone to tell me that they wrote their thesis without any macros so that I can get on with the job. I have been deciding for the past 5 hours what macros to have and what to call them. But I do not want to use them.
What are some good choices one can make with writing latex code? With programming there are ones like, write comments to clarify, write code that matches the symbols and names in the equations as much as possible.
