有没有办法在Julia中没有数据类型信息打印？

Question

例如：

.RunCommand

我希望julia> print([1,"2"]) Any[1, "2"] 成为控制台输出

对于复杂的数据类型，这会变得很难看。

Answer 1

你可能会使用这个丑陋的解决方法：

import Base.show
import Base.repr

function show(io::IO, a::Array{Any,1})
  print("[")
  first = true
  for i in a
    print(first ? "":",", repr(i))
    first = false 
  end
  print("]")
end

function repr(a::Array{Any,1})
  ret = "["
  first = true
  for i in a
    ret *= (first ? "":",") * repr(i)
    first = false 
  end
  ret *= "]"
end


julia> print([1,"2"])
[1,"2"]

julia> print([1,"2","t", [1,"2"]])
[1,"2","t",[1,"2"]]
