:MetalsShowCfr command not working

[caenrique]

Hi! I'm sure I'm missing something or doing something wrong but I cannot make the command :MetalsShowCfr work.
Running it in a file inside a project with Scala version 3.1.0 with

package package.name

case class Person(name: String)

gives me the message: [nvim-metals] Unsupported extension
whereas :MetalsShowJavap and :MetalsShowJavapVerbose work just fine

Hey @caenrique, what version of Metals are you using? You can do a :MetalsInfo and you should see it right up on top.

I'm not setting a specific version. The output of :MetalsInfo:

metals 0.10.9

Note:
Supported Scala versions:
Scala 3: 3.0.0, 3.0.1, 3.0.2, 3.1.0, 3.1.1-RC1
Scala 2:
2.11.12
2.12.15, 2.12.14, 2.12.13, 2.12.12, 2.12.11, 2.12.8, 2.12.9, 2.12.10
2.13.7, 2.13.4, 2.13.5, 2.13.6, 2.13.0, 2.13.1, 2.13.2, 2.13.3

Current settings

{
  excludedPackages = { "akka.actor.typed.javadsl", "com.github.swagger.akka.javadsl" },
  showImplicitArguments = true,
  showInferredType = true,
  superMethodLensesEnabled = true
}

Ah yea, that's the issue. You need to update. Doing a :MetalsUpdate should do the trick and get you 0.11.2. Keep in mind that nvim-metals doesn't "auto-update" mainly because we don't want to pay the cost of checking all the time or having it hard coded somewhere. So whenever a new version is released you'll need to :MetalsUpdate.

A totally different way to manage it is to use coursier. If you use cs to install metals and regularly do a cs update you can also tell nvim-metals to use that Metals that is globally installed by setting useGlobalExecutable.

nvim-metals/doc/metals.txt

Lines 440 to 449 in 3312490

	*useGlobalExecutable*
	Type: boolean ~
	Default: false ~
	For all you crazy Nix kids out there, or if you are want to re-use the same
	executable for multiple clients, this is for you. Please NOTE that by doing
	this, you are fully taking control of updating and installing Metals. Unless
	there is a specific reason that you want to manage your own version and
	install manually, then I'd recommend not using this setting and just letting
	`nvim-metals` handle it.

Oh, I didn't notice that! Thanks :)
