WorkspaceSymbols matches symbols across all views using the given query, according to the match semantics parameterized by matcherType and style.

The workspace symbol method is defined in the spec as follows:

The workspace symbol request is sent from the client to the server to
list project-wide symbols matching the query string.

It is unclear what "project-wide" means here, but given the parameters of workspace/symbol do not include any workspace identifier, then it has to be assumed that "project-wide" means "across all workspaces". Hence why WorkspaceSymbols receives the views []View.

However, it then becomes unclear what it would mean to call WorkspaceSymbols with a different configured SymbolMatcher per View. Therefore we assume that Session level configuration will define the SymbolMatcher to be used for the WorkspaceSymbols method.

    // "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.
    //   }
    // ...
    // }
    // ```
    Codelenses map[string]bool

    // SemanticTokens controls whether the LSP server will send
    // semantic tokens to the client.
    SemanticTokens bool `status:"experimental"`
}

type UserOptions Uses

type UserOptions struct {
    BuildOptions
    UIOptions
    FormattingOptions

    // VerboseOutput enables additional debug logging.
    VerboseOutput bool `status:"debug"`
}

UserOptions holds custom Gopls configuration (not part of the LSP) that is modified by the client.

func (*UserOptions) EnvSlice Uses

func (u *UserOptions) EnvSlice() []string

EnvSlice returns Env as a slice of k=v strings.

func (*UserOptions) SetEnvSlice Uses

func (u *UserOptions) SetEnvSlice(env []string)

SetEnvSlice sets Env from a slice of k=v strings.

type VersionedFileHandle Uses

type VersionedFileHandle interface {
    FileHandle
    Version() float64
    Session() string

    // LSPIdentity returns the version identity of a file.
    VersionedFileIdentity() VersionedFileIdentity
}

type VersionedFileIdentity Uses

type VersionedFileIdentity struct {
    URI span.URI

    // SessionID is the ID of the LSP session.
    SessionID string

    // Version is the version of the file, as specified by the client. It should
    // only be set in combination with SessionID.
    Version float64
}

type View Uses

type View interface {
    // Name returns the name this view was constructed with.
    Name() string

    // Folder returns the folder with which this view was created.
    Folder() span.URI

    // Shutdown closes this view, and detaches it from its session.
    Shutdown(ctx context.Context)

    // Options returns a copy of the Options for this view.
    Options() *Options

    // SetOptions sets the options of this view to new values.
    // Calling this may cause the view to be invalidated and a replacement view
    // added to the session. If so the new view will be returned, otherwise the
    // original one will be.
    SetOptions(context.Context, *Options) (View, error)

    // Snapshot returns the current snapshot for the view.
    Snapshot(ctx context.Context) (Snapshot, func())

    // Rebuild rebuilds the current view, replacing the original view in its session.
    Rebuild(ctx context.Context) (Snapshot, func(), error)

    // IsGoPrivatePath reports whether target is a private import path, as identified
    // by the GOPRIVATE environment variable.
    IsGoPrivatePath(path string) bool
}

View represents a single workspace. This is the level at which we maintain configuration like working directory and build tags.
