If I do something like version = Pkg.status(), then version is nothing. How do I save the output from Pkg.status() to a string variable?
All I need is just the package name with the version number in a human readable format, so Project.toml is not helpful. I notice a similar question here, but from what I understand the answer provided there let us save the output to a text file, and I wonder if there is a more direct way without saving it to a text file.
From the help page of Pkg.status()
See Pkg.project and Pkg.dependencies to get the project/manifest status as a Julia object instead of printing it.

What about:
io = IOBuffer()
Pkg.status(; io=io)
st = String(take!(io))
See also: https://github.com/ufechner7/PkgHelpers.jl/blob/main/src/PkgHelpers.jl
looking up the dictionary from Pkg.dependencies() is my current approach though I need to manually specify the package I’m checking. Pkg.project().dependencies is essentially just the Project.toml file and the UUID are not really helpful for my purpose. I’m just wondering if there’s a simple IO method where I can direct the output from Pkg.status() (something exactly what I need) to a string variable, something I thought was trivial but apparently not the case.
@ufechner7 just gave that to you above.

In case you also wanted to preserve the color output, use IOContext.
