How to switch JuliaPro to use the General registry?

Tooling
1

I wanted to try PackageCompiler, but JuliaPro registry has not included it yet:

(JuliaPro_v1.0.1.1) pkg> add PackageCompiler
  Updating registry at `C:\JuliaPro-1.0.1.1\pkgs-1.0.1.1\registries\JuliaPro`
  Updating git-repo `https://pkg.juliacomputing.com/registry/JuliaPro`
ERROR: The following package names could not be resolved:
 * PackageCompiler (not found in project, manifest or registry)
Please specify by known `name=uuid`.

I saw that the General registry included it:

However, I don’t know how to switch to use the General registry. I did find string “https://pkg.juliacomputing.com/” inside C:\JuliaPro-1.0.1.1\Julia-1.0.1\etc\julia\startup.jl and tried replacing it with “https://github.com/JuliaRegistries/General/” then restarting Julia, but that didn’t seem to work.

I also tried directly adding from GitHub, but was soon led to a rabbit hole of dependency tree:

(JuliaPro_v1.0.1.1) pkg> add https://github.com/JuliaLang/PackageCompiler.jl
  Updating git-repo `https://github.com/JuliaLang/PackageCompiler.jl`
[ Info: Assigning UUID e7f35708-9c4f-53ac-b576-fe1e8b0e8cf1 to PackageCompiler
 Resolving package versions...
ERROR: The following package names could not be resolved:
 * ArgParse (not found in project, manifest or registry)
 * SnoopCompile (not found in project, manifest or registry)
Please specify by known `name=uuid`.

etc. etc.

Does someone know how to switch JuliaPro to use the General registry (temporarily)? Thanks!

Just clone the General registry in the same folder where your JuliaPro registry lives (seemingly in C:\JuliaPro-1.0.1.1\pkgs-1.0.1.1\registries). Let us know if that does not work.

Sorry I have little experience dealing with software registries. Can you elaborate the steps to “clone the General registry”? Is it a file to be downloaded and copied into a folder? Don’t I need to change any settings of JuliaPro (e.g. the link in the startup.jl file I mentioned) so Julia knows where to search for a new package? Thanks!!!

You have three options:

  1. If you have Git installed, go to C:\JuliaPro-1.0.1.1\pkgs-1.0.1.1\registries, and execute git clone https://github.com/JuliaRegistries/General.git.
  2. If you don’t have Git or do not want to use it, go to GitHub - JuliaRegistries/General: The official registry of general Julia packages, click the button “Clone or download”, download it as a zip file, and extract it into C:/JuliaPro-1.0.1.1/pkgs-1.0.1.1/registries.
  3. You may use the LibGit2 module within Julia (it is available in the JuliaPro registry, so you should be able to install and use it). In this case:
pkg>add LibGit2
julia>using LibGit2
julia>LibGit2.clone("https://github.com/JuliaRegistries/General.git",
      "C:/JuliaPro-1.0.1.1/pkgs-1.0.1.1/registries/General")

There is nothing else to be done - except perhaps restart Julia.

Oops. Option no. 2 (download it as a zip) is not advisable, since the downloaded file is not a git repository, only a snapshot of the current version. So better use Git (in Julia with LibGit2 or as an external tool, as you prefer).

Thank you very much for the reply!

Yesterday to try the General registry I installed the standard Julia 1.0.1 and found it much faster to start and load a module than JuliaPro 1.0.1. So I will use the standard one for now and try the PackageCompiler over there. When I come back to JuliaPro in the near future I’ll try the cloning method you explained.

This should work, but a new version of JuliaPro will have an easy way to switch registries, since this seems to be a common request. Hopefully that will be released next week.

That sounds encouraging. Thanks!

About how long did it take to clone the git registries, mine has been running for 20 minutes now with no sign of progress…

@avik did that new version of JuliaPro come out yet with easy way to switch registries?
I just installed version 1.1.1.1 and I can’t find any documentation on how to use General.
