Ideas

[Andrew Kane]

Please create a new issue to discuss any ideas or share your own.

Explored, but on-hold

• More ways to install (Chocolatey or Scoop for Windows, Homebrew for Mac, packager.io for Linux)
• Add option to require all dependencies without library calls - jetpack.require() (could be slow, requires Jetpack as runtime dependency)
• Automatic dependency resolution (this could be a huge undertaking - maybe use something like https://github.com/r-lib/pkgdepends or https://github.com/CocoaPods/Molinillo)
• Remove desc to reduce dependencies down to 4
• No dependencies (vendor all code)
• Add ability to vendor packages in project - vendor_src branch
• Shortcut for specifying GitHub remotes
• Add ability to specify CRAN repo in DESCRIPTION or remote

[Susana Quartin]

One issue packrat hasn't solved is system dependencies (when installing older package versions from source). Any ideas to tackle that issue in jetpack?

[Andrew Kane]

Hey @quartin, I'm not familiar with that issue. Can you explain more, and give steps to reproduce if you have them?

[Susana Quartin]

Hey, I'm sorry for the huge delay. These sort of problems:

Hi @quartin, I've never encountered that error, but I'm not sure there's much Jetpack can do since it relies on Packrat (unless there's a known workaround for it).
