In metrumresearchgroup/rmotes: R Package Installation from Remote Repositories, Including 'GitHub'

rmotes

This is an experimental fork of r-lib/remotes with the intent of leveraging the remotes tooling to download the required remote packages, without doing any actual installations.

This will allow alternative, downstream tools, to use the downloaded repositories.

why?

remotes has extremely robust handling from repositories from all over the place with many settings. Rather than re-inventing the wheel, these modifications will allow as close to compatibility with remotes, while clearly deliniating what it is doing.

what's changed?

The biggest change is hooking into the install command(s) to not actually install, rather download and get to the point of installation but return there, without cleaning up the temporarily downloaded folders.

will this get merged in some way back to remotes?

Definitely not! The intent is not to add functionality, but rather to completely change what the package is doing. This wouldn't really make sense to fold back into remotes as it is a quite hacky.

how does it work?

For example, querying to download pkgman and credentials from github:

> rmotes::install_github(c("r-lib/pkgman", "r-lib/credentials"), force = TRUE, upgrade = FALSE)
Downloading GitHub repo r-lib/pkgman@master
Downloading GitHub repo r-lib/pkgdepends@master

The downloaded binary packages are in
    /var/folders/km/ljmnf0bx73l9m4zdygvb6q_80000gn/T//RtmpjsAoeq/downloaded_packages
Downloading GitHub repo jeroen/askpass@master

Now when checking the pkg src's, the folder where the downloaded package was unpacked is shown. As you can see, the dependencies are also captured.

If multiple configurations are specified for a given package, such as one dependency requiring a specific branch/pull request, whereas others just can take the tip, this will show up as multiple hashes for the given package.

As this does not do any futher solving to determine compatibility, that is left up to the user/admin to determine the subsequent course of action.
