In python pip packages you can declare "bin" scripts which become available in path to execute. It's a simple feature but it allows you to use the system to distribute simple "programs" as well as libraries. I can see there's no obvious way of providing the same functionality in julia, but if I

Re: [julia-users] Re: how to pass function as argument?

Like so: *function func(ff::Function) * * ff(4) * *end * Note that functions have not a more specialised type as they do in some other languages, like for example (Int, Float64) -> (Float,), they are just a `Function`. > By the way what is the advantage of setting the type ? Is it only for "s

Re: [julia-users] Re: how to pass function as argument?

Ok but how to set the type in the declaration of the arguments ? *function func(ff::???) * * ff(4) * *end * By the way what is the advantage of setting the type ? Is it only for "safe programming" (I mean my code will generate an error if I specify the type and pass something having anothe

Re: [julia-users] negative power throws error

A Float is a decimal number, hence it also is a rational number : *2.243423592592582385923 = 2243423592592582385923 / 10* Hence, depending on the limitations about the sizes of the integers, the set Rational could be bigger than the set Float. In this case, the better appr

Re: [julia-users] Re: how to pass function as argument?

That is to normal way to do it, except that your definition > ff(i::Int) = f2(i::Int) is not necessary. Just do julia> func(f2) 20.0 julia> func(f1) 40.0 Functions can just be passed around with their name, just like any other variable. The difference only comes once you add the `(...)` to it,

Re: [julia-users] Experimental package documentation package.

I just fixed it up to work with n level headers – it should do everything you need it to now. Just to get you started, this will render the first docstring from docile.md: julia> Markdown.Block(Markdown.parse_file("/users/Mike/Documents/docile.md")[3:7]) julia> sprint(Markdown.terminal_print,
