Is there a way to get a list of available versions of a package?

I’m trying to get ahead on updating my code for Julia 0.6 but a package my code depends on, DataFrames, doesn’t work in 0.6 when I simply use `Pkg.add`; it fails on percompilation. I’ve checked the DataFrames Github page but it wasn’t clear to me if there was a working version for 0.6.

You can use Git for a hacked solution:

```bash
cd ~/.julia/v0.5/DataFrames
git tag --list v*

```

and you can run these commands from Julia too:

```julia
cd(Pkg.dir("DataFrames"))
versions = split(readstring(`git tag --list v*`), '\n')

```

Nice to know. Unfortunately there’s no context to the version, which one works in 0.6? 0.5? etc

In that case, I don’t see other solution other than inspecting the REQUIRE file for each version tag. If you add `DataFrames` in `Julia v0.6` and it fails saying that there is no support for that version, then you have to wait for a new release of `DataFrames`.

How do you list versions not in the master branch?

`Pkg.available` is not available 😛 in 1.7.2, is there a new method for that?

A slight modification of [Reading versions of a package from unpacked registry tarball - #2 by GunnarFarneback](https://discourse.julialang.org/t/reading-versions-of-a-package-from-unpacked-registry-tarball/76829/2) should give you a list of versions. But if you want it in the context of versions of some package you have as a dependency, [PackageCompatUI](https://github.com/GunnarFarneback/PackageCompatUI.jl) is a more convenient tool.

Indeed, thank you!

```julia
function available_versions(pkgname::AbstractString)
    registry = only(filter(r -> r.name == "General", Pkg.Registry.reachable_registries()))
    pkg = only(filter(pkg -> pkg.name == pkgname, collect(values(registry.pkgs))))
    return keys(Pkg.Registry.registry_info(pkg).version_info)
end

```
