问题描述
如何获取Julia会话的已导入/已使用软件包的列表?
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()的输出可以捕获到变量中吗?
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)然后将为您提供当前已加载模块的列表.
children(Main) will then give you a list of modules currently loaded.
我在这里将Lazy.jl用于画眉宏(@>>)，但是您可以不那么容易地重写它:
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，您可以将&& x ≠ Lazy添加到filter以避免包含它.
Alternatively you could add && x ≠ Lazy to the filter to avoid including it.
