methods - 我能让 Julia 忘记 REPL 中的方法吗

Question

如果我在 REPL 中玩并且我为函数定义了几种不同的方法:

julia> methods(next)
# 3 methods for generic function "next":
next(i::BigInt) at none:1
next(i::Int64) at none:1
next(i) at none:1

我能让 Julia 忘记其中一些或全部吗？

Answer 1

简而言之，不。

Julia does not have an analog of MATLAB’s clear function; once a name is defined in a Julia session (technically, in module Main), it is always present.

If memory usage is your concern, you can always replace objects with ones that consume less memory. For example, if A is a gigabyte-sized array that you no longer need, you can free the memory with A = 0. The memory will be released the next time the garbage collector runs; you can force this to happen with gc().
