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.

To enable all experimental features, use allExperiments: true. You will still be able to independently override specific experimental features.

buildFlags []string

buildFlags 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.

Default: [].

env map[string]string

env adds environment variables to external commands run by gopls, most notably go list.

Default: {}.

hoverKind enum

hoverKind controls the information that appears in the hover text. SingleLine and Structured are intended for use only by authors of editor plugins. Must be one of:

  • "FullDocumentation"

  • "NoDocumentation"

  • "SingleLine"

  • "Structured" is an experimental setting that returns a structured hover format. This format separates the signature from the documentation, so that the client can do more manipulation of these fields.
    This should only be used by clients that support this behavior.

  • "SynopsisDocumentation"

Default: "FullDocumentation".

usePlaceholders bool

placeholders enables placeholders for function parameters or struct fields in completion responses.

Default: false.

linkTarget string

linkTarget controls where documentation links go. It might be one of:

  • ""
  • ""

If company chooses to use its own, its address can be used as well.

Default: "".

local string

local 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: "".

gofumpt bool

gofumpt indicates if we should run gofumpt formatting.

Default: false.


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.

Default: {}.

codelens map[string]bool

codelens overrides the enabled/disabled state of code lenses. See the “Code Lenses” section of for the list of supported lenses.

Example Usage:

"gopls": {
  "codelens": {
    "generate": false,  // Don't show the `go generate` lens.
    "gc_details": true  // Show a code lens toggling the display of gc's choices.

Default: {"gc_details":false,"generate":true,"regenerate_cgo":true,"tidy":true,"upgrade_dependency":true,"vendor":true}.

completionDocumentation bool

completionDocumentation enables documentation with completion results.

Default: true.

completeUnimported bool

completeUnimported enables completion for packages that you do not currently import.

Default: true.

deepCompletion bool

deepCompletion enables the ability to return completions from deep inside relevant entities, rather than just the locally accessible ones.

Consider this example:

package main

import "fmt"

type wrapString struct {
    str string

func main() {
    x := wrapString{"hello world"}

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

Default: true.

matcher enum

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

  • "CaseInsensitive"
  • "CaseSensitive"
  • "Fuzzy"

Default: "Fuzzy".

annotations map[string]bool

annotations suppress various kinds of optimization diagnostics that would be reported by the gc_details command.

  • noNilcheck suppresses display of nilchecks.
  • noEscape suppresses escape choices.
  • noInline suppresses inlining choices.
  • noBounds suppresses bounds checking diagnostics.

Default: {}.

staticcheck bool

staticcheck enables additional analyses from

Default: false.

symbolMatcher enum

symbolMatcher sets the algorithm that is used when finding workspace symbols. Must be one of:

  • "CaseInsensitive"
  • "CaseSensitive"
  • "Fuzzy"

Default: "Fuzzy".

symbolStyle enum

symbolStyle controls how symbols are qualified in symbol responses.

Example Usage:

"gopls": {
  "symbolStyle": "dynamic",

Must be one of:

  • "Dynamic" uses whichever qualifier results in the highest scoring match for the given symbol query. Here a “qualifier” is any “/” or “.” delimited suffix of the fully qualified symbol. i.e. “to/pkg.Foo.Field” or just “Foo.Field”.

  • "Full" is fully qualified symbols, i.e. “path/to/pkg.Foo.Field”.

  • "Package" is package qualified symbols i.e. “pkg.Foo.Field”.

Default: "Package".

linksInHover bool

linksInHover toggles the presence of links to documentation in hover.

Default: true.

tempModfile bool

tempModfile controls the use of the -modfile flag in Go 1.14.

Default: true.

importShortcut enum

importShortcut specifies whether import statements should link to documentation or go to definitions. Must be one of:

  • "Both"
  • "Definition"
  • "Link"

Default: "Both".

verboseWorkDoneProgress bool

verboseWorkDoneProgress controls whether the LSP server should send progress reports for all work done outside the scope of an RPC.

Default: false.

semanticTokens bool

semanticTokens controls whether the LSP server will send semantic tokens to the client.

Default: false.

expandWorkspaceToModule bool

expandWorkspaceToModule instructs gopls to adjust the scope of the workspace to find the best available module root. gopls first looks for a go.mod file in any parent directory of the workspace folder, expanding the scope to that directory if it exists. If no viable parent directory is found, gopls will check if there is exactly one child directory containing a go.mod file, narrowing the scope to that directory if it exists.

Default: true.

experimentalWorkspaceModule bool

experimentalWorkspaceModule opts a user into the experimental support for multi-module workspaces.

Default: false.

experimentalDiagnosticsDelay time.Duration

experimentalDiagnosticsDelay controls the amount of time that gopls waits after the most recent file modification before computing deep diagnostics. Simple diagnostics (parsing and type-checking) are always run immediately on recently modified packages.

This option must be set to a valid duration string, for example "250ms".

Default: "0s".

experimentalPackageCacheKey bool

experimentalPackageCacheKey controls whether to use a coarser cache key for package type information to increase cache hits. This setting removes the user's environment, build flags, and working directory from the cache key, which should be a safe change as all relevant inputs into the type checking pass are already hashed into the key. This is temporarily guarded by an experiment because caching behavior is subtle and difficult to comprehensively test.

Default: true.


The below settings are for use in debugging gopls. Like the experimental options, they may be deprecated or changed in the future.

verboseOutput bool

verboseOutput enables additional debug logging.

Default: false.

completionBudget time.Duration

completionBudget is the soft latency goal for completion requests. Most requests finish in a couple milliseconds, but in some cases deep completions can take much longer. As we use up our budget we dynamically reduce the search scope to ensure we return timely results. Zero means unlimited.

Default: "100ms".

generate runs go generate for a given directory.
