build(deps): bump golang.org/x/tools/gopls from 0.17.1 to 0.18.0

[dependabot]

Bumps golang.org/x/tools/gopls from 0.17.1 to 0.18.0.

Release notes

Sourced from golang.org/x/tools/gopls's releases.

gopls/v0.18.0

This release contains some small changes to gopls behavior, bug fixes, and new features.

Notably, the new modernize analyzer reports hint diagnostics suggesting ways that Go code could be updated to take advantage of new Go language features and standard library APIs. If hint level diagnostics are noisy in your editor, and you find these diagnostics disruptive, you can disable these analyses by setting:

"analyses": {
  "modernize": false
}

Configuration Changes

• The experimental Structured value for the hoverKind option is no longer supported.

• The gc_details code lens has been deleted. (It was previously disabled by default.) This functionality is now available through the toggleCompilerOptDetails code action, described below, as code actions are better supported than code lenses across a range of clients.

  VS Code's special "Go: Toggle GC details" command continues to work.

• The experimental semanticTokenTypes and semanticTokenModifiers options allow selectively disabling certain types of tokens or token modifiers in textDocument/semanticTokens responses.

  These options supersede the noSemanticString and noSemanticTokenNumber options, which are now deprecated. Users can instead set "semanticTokenTypes": {"string": false, "number": false} to achieve the same result. For now, gopls still honors noSemanticTokenString and noSemanticToken, but will stop supporting them in a future release.

• The new workspaceFiles option allows configuring glob patterns matching files that define the logical build of the workspace. This option is only needed in environments that use a custom golang.org/x/tools/go/packages driver.

New features

"{Show,Hide} compiler optimization details" code action

This code action, accessible through the "Source Action" menu in VS Code, toggles a per-directory flag that causes Go compiler optimization details to be reported as diagnostics. For example, it indicates which variables escape to the heap, and which array accesses require bounds checks.

New modernize analyzer

Gopls now reports when code could be simplified or clarified by using more modern features of Go, and provides a quick fix to apply the change.

For example, a conditional assignment using an if/else statement may be replaced by a call to the min or max built-in functions added in Go 1.18.

Use this command to apply modernization fixes en masse:

$ go run golang.org/x/tools/gopls/internal/analysis/modernize/cmd/modernize@latest -fix -test ./...

We are aware of a number of minor bugs in the analyzer's fixes. For example, it may sometimes cause a variable or an import to become unused, or may delete comments within a for or if block that is simplified to a library call. The known bugs are low-risk and easy to fix, as they result in a broken build or are obvious during a code review; none cause latent behavior changes. Please report any additional problems you encounter.

New unusedfunc analyzer

Gopls now reports unused functions and methods, giving you near real-time feedback about dead code that may be safely deleted. Because the analysis is local to each package, only unexported functions and methods are candidates. It may yield false positives for functions referenced only from assembly code, or build-tagged files not part of the current configuration.
