Julia: is there a function to obtain the version number of a package?

I see that Pkg.status("PkgName") prints something like this Pkg v0.12.0 to the REPL.

I tried to @edit Pkg.status("Pkgname") but encountered some macro code that I don't understand.

What's the easiest way to obtain the version number of a package in the current activate environment?

Pkg.installed() does give you the version of all installed packages as version strings, but it is deprecated and is likely to be removed in future versions of julia

julia> Pkg.installed()
ā”Œ Warning: Pkg.installed() is deprecated
ā”” @ Pkg ~/julia/usr/share/julia/stdlib/v1.5/Pkg/src/Pkg.jl:561
Dict{String,VersionNumber} with 81 entries:
  "Interact"                    => v"0.10.3"
  "ForwardDiff"                 => v"0.10.12"
  "UMAP"                        => v"0.1.6"
  "Juno"                        => v"0.8.2"

Currently you can use Pkg.dependencies() to get all information about all packages, as it was discussed here. For example

using Pkg

julia> filter(x-> x.second.name == "Crayons", Pkg.dependencies()) |> x -> first(x)[2].version   
v"4.0.1"
