Regarding single-letter variables, mathematical functions might be an exception. I think writing func gcd(a, b int) int {...} is better than other alternatives.

Regarding single-letter variables, mathematical functions might be an exception. I think writing func gcd(a, b int) int {...} is better than other alternatives. There is simply no need to assign any more meaning to the arguments other than their type.
- bnolsen 8y agono, it's not. bigger deal is that single letter vars make it much harder to search for variable usage in files using arbitrary editors.
- apoorvgarg 8y agoWhat would be the signature of your gcd function ?
- base698 8y agoNumerator, denominator?
- coldtea 8y agoGood luck with any bigger equation then
- mrgriffin 8y agoFor GCD? I would find those names very misleading since semantically the order of the arguments to GCD is irrelevant (even if in the implementation you typically mod by b there's no reason you couldn't mod by a).
- sacado2 8y agoThis is not mathematically correct. Those names would be pretty misleading, actually.
- coldtea 8y agoDon't use arbitrary editors, or editors that don't support "search for standalone identifier" (e.g. surrounded by space, in (), with ; after etc.".
- Cthulhu_ 8y agoMaybe if you - and more importantly, everyone that will read the code in the future - are comfortable with domain-specific expressions like that. It depends on the audience really. As an extreme example, scalaz is similarly a very specialized DSL. Or in my personal experience, functional constructions like map, flatMap, foldLeft and reduce (which I never learned in school).
