Julia 中加载/导入的包列表 [英] List of loaded/imported packages in Julia

问题描述

如何获取 Julia 会话的导入/使用包列表?

How can I get a list of imported/used packages of a Julia session?

Pkg.status() 列出所有已安装的软件包.我对通过 using ... 或 import ...

Pkg.status() list all installed packages. I'm interested in the ones that that were imported/loaded via using ... or import ...

似乎 whos() 包含相关信息(名称以及是否为模块).whos() 的输出能否被捕获到变量中?

It seems that whos() contains the relevant information (the names and whether it is a module or not). Can the output of whos() be captured in a variable?

推荐答案

using Lazy
children(m::Module) =
  @>> names(m, true) map(x->m.(x)) filter(x->isa(x, Module) && x ≠ m)

children(Main) 然后会给你一个当前加载的模块列表.

children(Main) will then give you a list of modules currently loaded.

我在这里使用 Lazy.jl 作为画眉宏 (@>>)，但您可以轻松地重写它:

I used Lazy.jl here for the thrush macro (@>>), but you can rewrite it without easily enough:

children(m::Module) =
  filter(x->isa(x, Module) && x ≠ m, map(x->m.(x), names(m, true)))

或者，您可以添加 &&x ≠ Lazy 到 filter 以避免包含它.

Alternatively you could add && x ≠ Lazy to the filter to avoid including it.
