I would like to have a function that returns the name of the function in the argument, e.g.: function give_me_my_name(f::Function) return ??? (f); end such that give_me_my_name(sin) returns sin as a string. How do I do that?

julia> function give_me_my_name(f::Function) return String(Symbol(f)) end give_me_my_name (generic function with 1 method) julia> give_me_my_name(sin) "sin"

julia> give_me_my_name(give_me_my_name) "give_me_my_name" :grin:

Awesome! Thanks! The best about Julia is that brought child-like fun of programming back to me — but a close second is that fantastic helpful & fun Julia-Community!!! So cool!

How do you do this for a mutable struct? String(Symbol(X)) does not yield the name…

Its just the same: julia> mutable struct mutable_struct x end julia> typeof(mutable_struct) DataType julia> function give_me_my_name(s::DataType) return String(Symbol(s)) end give_me_my_name (generic function with 2 methods) julia> give_me_my_name(mutable_stru…

You can do it generic: julia> function give_me_my_name(whatever) return String(Symbol(whatever)) end give_me_my_name (generic function with 3 methods) julia> give_me_my_name(Int) "Int64"

Sorry, I explained myself badly: Variablenames are only accessible by Macros, right? For mutable struct mutable_struct x y z end var = mutable_struct(1,2,3); function give_me_my_name(s::mutable_struct) return String(Symbol(s)) end give_me_my_name(var) I get "mutable_struct(…

No, I don’t think this is possible with a function. In the function it would be the function parameters name and not var anymore.
