Understanding package versions

[Willmo36]

Hey there,

I've psc-package install react-basic'd in order to try out the react-basic counter example and there seems to be a mismatch of version. The current psc-package set has react-basic at version 6.2.0 which I believe is below the version used in their example and causing me some grief with the example code.

How (if even possible) would I get resolve this using psc-package? My impression is the version of react-basic is locked down to the package set itself.

Also, spacchetti has v8.0.0 of react-basic. I'm not sure what this implies regarding the lifecycle of a package set or the status of psc-package itself (as in, should I be using spacchetti instead?).

Thanks for all your efforts on this project!

spacchetti is an alternative to package-sets that I personally manage, but I also manage package-sets from community contributions. It is not an alternative to psc-package, as it is only a package set.

To get a specific version of react-basic, you have four options:

1. Like you have pointed out, spacchetti has 8.0.0 in master. You can consume the tag that has this: https://github.com/spacchetti/spacchetti/releases/tag/20190131. See https://spacchetti.readthedocs.io/en/latest/ for more details.
2. You can fork package-sets to add what you want. See https://psc-package.readthedocs.io/en/latest/maintenance.html. You should try to upstream your changes here.
3. You can use the spago tool and patch the package in the package set, using a language called Dhall: https://github.com/spacchetti/spago
4. You can use the spago tool to create a custom package set for consuming with psc-package: https://spacchetti.readthedocs.io/en/latest/local-setup.html

Most users will be able to just use (1) and continue without any further problems.
