How to sublimetext:

1) install LSP package
2) Add this to user settings :

"clients":
	{
		"amycd":
		{
			"command":
			[
				"sbt",
				"run"
			],
			"enabled": true,
			"languages":
			[
				{
					"languageId": "amyc",
					"scopes":
					[
						"source.amy",
						"source.scala"
					],
					"syntaxes":
					[
						"Packages/Scala/Scala.sublime-syntax"
					]
				}
			]
		}
	},

Note: With the previous command/setting, you need to edit code in tha same project as the amyc language server (since it runs naivly and doesnt exist in the PATH or as an alias)

3) Open a .amy file
4) Set Syntax to scala
5) Start LSP server
