Visual Studio Code: gopls and YAML

The Go team is developing a Language Server Protocol [LSP] implementation) called gopls. Visual Studio Code (and others) support LSP. Other languages (e.g. Python have LSP implementations too). I’ve been using gopls for some time. It works (mostly) very well and replaces multiple, indepedent tools with two (gopls and delve).

My Visual Studio Code settings that include gopls is:

    "go.autocompleteUnimportedPackages": true,
    "go.useLanguageServer": true,
    "[go]": {
        "editor.snippetSuggestions": "none",
        "editor.formatOnSave": true,
        "editor.codeActionsOnSave": {
            "source.organizeImports": true
        }
    },
    "gopls": {
        "usePlaceholders": true,
        "wantCompletionDocumentation": true,
    },
    "go.toolsEnvVars": {
    },
    "go.languageServerFlags": [
        "-rpc.trace",
        "serve",
        "--debug=localhost:6060",
    ],
    "go.enableCodeLens": {
        "references": true,
        "runtest": true
    },

One of the Google engineers working on gopls gave a comprehensive and interesting overview of the tool at GopherCon 2019.
