Settings

This document describes the global settings for gopls inside the editor. The settings block will be called "gopls" and contains a collection of controls for gopls that the editor is not expected to understand or control. These settings can also be configured differently per workspace folder.

In VSCode, this would be a section in your settings.json file that might look like this:

  "gopls": {
    "usePlaceholders": true,
    "completeUnimported": true
  },

Officially supported

Below is the list of settings that are officially supported for gopls.

buildFlags array of strings

This is the set of flags passed on to the build system when invoked. It is applied to queries like go list, which is used when discovering files. The most common use is to set -tags.

env map of string to value

This can be used to add environment variables. These will not affect gopls itself, but will be used for any external commands it invokes.

hoverKind string

This controls the information that appears in the hover text. It must be one of:

• "NoDocumentation"
• "SynopsisDocumentation"
• "FullDocumentation"

Authors of editor clients may wish to handle hover text differently, and so might use different settings. The options below are not intended for use by anyone other than the authors of editor plugins.

• "SingleLine"
• "Structured"

Default: "SynopsisDocumentation".

usePlaceholders boolean

If true, then completion responses may contain placeholders for function parameters or struct fields.

Default: false.

linkTarget string

This controls where points documentation for given package in textDocument/documentLink. It might be one of:

• "godoc.org"
• "pkg.go.dev" If company chooses to use its own godoc.org, its address can be used as well.

Default: "pkg.go.dev".

local string

This is the equivalent of the goimports -local flag, which puts imports beginning with this string after 3rd-party packages. It should be the prefix of the import path whose imports should be grouped separately.

Default: "".

Experimental

The below settings are considered experimental. They may be deprecated or changed in the future. They are typically used to test experimental opt-in features or to disable features.

analyses map[string]bool

Analyses specify analyses that the user would like to enable or disable. A map of the names of analysis passes that should be enabled/disabled. A full list of analyzers that gopls uses can be found here

Example Usage:

...
"analyses": {
  "unreachable": false, // Disable the unreachable analyzer.
  "unusedparams": true  // Enable the unusedparams analyzer.
}
...

codelens map[string]bool

Overrides the enabled/disabled state of various code lenses. Currently, we support two code lenses:

• generate: [default: enabled] run go generate as specified by a //go:generate directive.
• upgrade.dependency: [default: enabled] upgrade a dependency listed in a go.mod file.
• test: [default: disabled] run go test -run for a test func.

By default, both of these code lenses are enabled.

completionDocumentation boolean

If false, indicates that the user does not want documentation with completion results.

Default value: true.

completeUnimported boolean

If true, the completion engine is allowed to make suggestions for packages that you do not currently import.

Default: false.

deepCompletion boolean

If true, this turns on the ability to return completions from deep inside relevant entities, rather than just the locally accessible ones.

Default: true.

Consider this example:

package main

import "fmt"

type wrapString struct {
    str string
}

func main() {
    x := wrapString{"hello world"}
    fmt.Printf(<>)
}

At the location of the <> in this program, deep completion would suggest the result x.str.

fuzzyMatching boolean

If true, this enables server side fuzzy matching of completion candidates.

Default: true.

staticcheck boolean

If true, it enables the use of the staticcheck.io analyzers.

matcher string

Defines the algorithm that is used when calculating completion candidates. Must be one of:

• "fuzzy"
• "caseSensitive"
• "caseInsensitive"

Default: "caseInsensitive".

symbolMatcher string

Defines the algorithm that is used when calculating workspace symbol results. Must be one of:

• "fuzzy"
• "caseSensitive"
• "caseInsensitive"

Default: "caseInsensitive".
