misleading info regarding windows installation

[amitport]

Currently, in the "getting started" guide it says:

If you are a Linux or Windows user, download the latest release. Optionally add path of the folder bin/ to the system environment variable PATH.

Now you can compile Scala source code:
scalac hello.scala

This does not seem to be the case. On windows, it seems that one needs to setup bash (and JAVA_HOME set to ???<=JDK<=13) (I know, it seems trivial to scala developers, but, the instructions are annoying for someone who hasn't used it in a while and just want to checkout dotty/scala3 as a new language)

@amitport This is indeed not the case. Currently the Scala 3 distribution doesn't provide batch commands for Windows users. For now I suggest you to follow one of the two paths:

• the short path : install the following batch files into the bin\ directory of your Scala 3 installation.
• the long path : read my GitHub page Running Scala 3 on Windows.

Hey, thank you. I'm running on wsl and it's working fine (after some JAVA_HOME interoperability mess). I just posted this issue because I feel that the documention should reflect the current situation more clearly.

Does the explanation provided on this page work better for you?

https://docs.scala-lang.org/scala3/getting-started.html

If yes, then we could "backport" the explanations to the old dotty.epfl.ch page.

@b-studios I think it's still missing parts about running with bash environment or the bat scripts in https://github.com/michelou/dotty-examples/tree/master/bin/3.0.0

(I haven't tried to install again recently, I'm not really developing anything in scala 3 just experimented with it at the time, and back then I used WSL to make it work)

@amitport I would have assumed that the missing bat scripts are taken care of by coursier? Sadly, I do not have a windows installation available where I could test this appropriately.

EDIT: I tried to install Scala 3 with coursier. Running coursier install scala of course installs Scala 2 and there is a dotty-repl target. But you are right: it does not install the bat files to run Scala 3.

EDIT2: Alexandre told me that there are already commands for Scala 3 available: coursier/apps#81

@amitport I updated the landing page in #11032 to mention that we recommend some bash-like environment. I think at the current point this is easier then also asking to install the necessary scripts. What do you think?

[amitport]

Looks much better. It's important that it doesn't hide the complexity involved. Thank's, can be closed IMO
