How am I supposed to create and distribute packages in Julia 0.7/1.0 ?

I am quite confused about the package situation in Julia at the moment. I’ve worked with the previous package manager and followed to guides for how to make a package and distribute it. Like how you register it, make sure it is tagged properly, has automatic build etc.

However for the new package manager Pkg3, I can’t figure out how the process is supposed to work. The Julia documentation explains how to create your own package. But I am unable to obtain any information on how you distribute this package. I’ve looked at other packages on Github, but they all seem to use the old Pkg2 config files. I don’t see the Manifest.toml and Config.toml files e.g. in the Github repos.

I see the REQUIRE file, but isn’t that a Pkg2 thing?

Or can Pkg3 in fact use Pkg2 formatted package repositories?

Yes, exactly. You can just keep doing exactly what you were doing before. The tooling for automatically creating project files and registering Pkg3-only packages will improve in the future, but for now you can keep listing requirements in REQUIRE and tagging releases with GitHub + AttoBot.


Thanks, very useful feedback. Would you mind elaborating a bit more on your typical workflow for creating a package under Julia 0.7 for distribution. Do you use the Pkg3 terminal mode to generate a package and then just manually add a REQUIRE file, or do you use the old Pkg.generate() function? And why do I not see people check in Project.toml and Manifest. toml files in addition to REQUIRE in their repositories?

I was actually not aware of AttoBot. I wish the standard Julia documentation said more about these kinds of workflows. I have relied primarily on the julia website and reading documentation there. I used PkgDev in the past. Is that not recommended anymore? Does anyone have any write up of best practices for distributing Julia packages since 0.7?

AFAIK 1.0 support is WIP:
