如何查看 Julia 包中的方法列表 [英] How can I see the list of methods in a Julia Package

问题描述

Julia 中有没有列出包中所有可用方法的命令?

Is there a command in Julia that lists all the methods that are available in a package?

例如我加载 Distributions

For example I load up Distributions

using Distributions

现在我想看看调用什么函数从正态分布中抽取随机值.有没有一个好方法可以在没有谷歌搜索的情况下从 Julia 内部做到这一点?

and now I would like to see what function to call to draw a random value from a normal distribution. Is there a good way to do this from inside of Julia without a google search?

推荐答案

有点，虽然我认为它没有多大用处:

Sort of, although I don't think its of much utility:

julia> using Distributions

julia> names(Distributions)
215-element Array{Symbol,1}:
 :median
 :logpdf
 :logpmf!
 :Chisq
 :posterior_rand
 :fit_mle!
 :NegativeBinomial
 :posterior_rand!
 :ContinuousMatrixDistribution
 :ValueSupport
 :InverseGamma
 :complete
 :TDist
 :NormalCanon
 :SufficientStats
 :Chi
 :logpmf
 :logdetcov
 :Gumbel
 :Sampleable
 ...

或以非编程方式，使用

julia> whos(Distributions)
AbstractMixtureModel          DataType
AbstractMvNormal              DataType
Arcsine                       DataType
Bernoulli                     DataType
Beta                          DataType
BetaPrime                     DataType
Binomial                      DataType

我认为，通过在 Julia 0.4 中包含内置文档系统，我们将获得更多包含 REPL 可用文档的软件包.

I think that with the inclusion of an inbuilt documentation system in Julia 0.4, we'll get way more packages with docs available at the REPL.
