是否可以将数组转换为函数的参数列表？

Question

I have a function that accepts n number of parameters (it's the devinus/sh function) where you can execute a command line program and obtain the results:

Example: Sh.file "-b", "--mime-type", path_to_file

But I want to have the parameters in an array so they can be varying depending on how the function is called.

Example of what I want:

data = ["-b", "--mime-type", path_to_file]

# a way of going through the array and turning it into the parameters for the Sh function

Sh.file <loop array params here>

Sh doesn't take an array for a parameter.

Any ideas?

Answer 1

你可以使用apply(Sh, :file, args) ，其中args是一个参数数组。
