A question about redefining a function in Julia

[eldee]

When we handle our functions in practice, it would be perfect if we define and call standard functions (at the definition, all names are read from the arg line; at the caller’s place, we specify all arguments). But this style in practice would soon become very cumbersome. Imagine if you have a function with a long arg list, and that function still needs to be wrapped within a “shell” function. So that “shell” function also has to define a long list of args.

There already have been a number of topics on how to organise many method arguments, such as

Good coding practices: How to cluster many variables in function argument

Hello there, I’m still fairly new to julia, but I guess it is anyway a general programming question. In my code there are several physical parameters, e.g. mass,speed,height,… as well as numerical parameters for different numerical methods used subsequently, e.g. n1,n2,n3,…, and m1,m2,m3,… (In reality I give them more useful names). Now I wrote a function which does the main calculation function fun_unclear(mass,speed,height,n1,n2,n3,m1,m2,m3) end However, as there are so many arguments (ar…

and we are starting to get off-topic here, but in general you would just group your arguments into (one or multiple) structs, (named) tuples, …

As you can see, the standard grammar in arg.jl is very cumbersome.

This example is also just very artificial. You destructure your generator to 19 variables, which you then later combine again. Instead you could have just defined (e.g.) vec = Tuple(rand(1000) for _ = 1:19) and function loop_over_global(vec) ... end.
