the only value returned is 7.4.0-M7, signifying that it's the only one published for Scala 3
@jsatk: the same thing I just mentioned up above can also be done. I just took a peek, and 3.1.0 doesn't exist for Scala 3
❯ cs complete org.typelevel:cats-effect_3:
2.5.1
3.1.1
3.2.0
btw since I know you use Neovim, you can also always double check this using the built in coursier stuff in the
scala-utils plugin, right inside Neovim
Thank you as always
apologies, but i'm still very confused. I set the versions correct as far as I know http://i.jsatk.us/u3SHxc
It looks like it thinks I'm on scala 3?
@jsatk: you'll want to put the version in there as well, like
cs launch com.lihaoyi:ammonite_2.13.4:2.1.4 ammonite.Main -- script.sc
I read through most of the Ammonite docs yesterday and't still couldn't quite figure it out.
afaik, ammonite doesn't have a great way to dynamically switch Scala versions, since by default it will use the version of Scala that it was installed with. In your case 3.x it looks like
so a way to get around that is to launch ammonite with coursier so you can directly easily specify the version of Scala and the version of ammonite
$ cs launch com.lihaoyi:ammonite_2.13.0:2.1.4 -M ammonite.Main

Do I have some version set wrong here or...?
for example let's take cats-core as an example
you're trying to pull in 2.13.0 published for 2.13
however, there is no 2.13.0 that is published for 2.13
you can see this with
cs complete org.typelevel:cats-core_2.13:
holy cow. This is...
not intuitive.
Earlier I ran just
cs complete org.typelevel:cats-core and that's how I got 2.13. Didn't realize I needed to specify that bit to see what versions are available for scala 2.13.
Sorry. Clearly I'm still a newbie with the tooling.
yea so not to go too far into cs on an Ammonite channel, but complete completes as far as it can basically until a
:, so your completion should have given you any artifact that starts with cats-core including the cross endings of _2.13 etc. If you want the specific version of scala specified, then always make sure to use the full org:artifact_withscalversion:
so
cs complete org.typelevel:cats-core_2.13: for the 2.13 artifacts and cs complete org.typelevel:cats-core_3: for the Scala 3 artifacts
or just look on maven central or another webpage if a gui is more your thing
but I know it's not 😉

I got past the previous step. Now I get ☝️
My goals are, I think, simple. I want to run ammonite with scala version 2.13 (and sometimes 2.12) and I want it to have the cats libraries available globally.
you're free to try to get it working, but it's not the common path, and you need to know that you'll need to sort through any issues that arise
looks to me like you have some wrong scala version on the classpath somewhere
that's likely a result of trying to get both scala 212 and 213 working
might be a bug in Ammonite, but an easy workaround is to jusy stick with 2.13 wrt the book
