gopls/internal/lsp/cache: recreate Views when their root changes A View is defined by a Go environment along with a go.work file, go.mod file, or directory in GOPATH. When the environment changes via didChangeConfiguration, we recreate the View. Before this CL we didn't do the same when a view-defining go.mod or go.work was added or removed. Instead, we relied on workspace and snapshot invalidation to get us to the correct state. But since we reinitialize the view on these changes anyway there is little value in preserving any existing view state, and in fact doing so may lead to latent bugs. For example, deleting a go.work file caused the workspace to fall back to 'file system' mode, which may not be the same state that would result from restarting gopls. This change also moves us toward a model where we can have a dynamic set of views covering the full set of open files, not 1:1 with workspace folders. Also: - move the dirURI helper function to span.Dir, which is more discoverable - fix a bug where the wrong filter function was used to define the workspace - remove Session.optionsOverride, which was unused For golang/go#55331 Change-Id: Id108e848cdd942c34eda0a339d2c8a517c89c7de Reviewed-on: https://go-review.googlesource.com/c/tools/+/459635 TryBot-Result: Gopher Robot <gobot@golang.org> gopls-CI: kokoro <noreply+kokoro@google.com> Run-TryBot: Robert Findley <rfindley@google.com> Reviewed-by: Alan Donovan <adonovan@google.com>
This repository provides the golang.org/x/tools module, comprising various tools and packages mostly for static analysis of Go programs, some of which are listed below. Use the “Go reference” link above for more information about any package.
It also contains the golang.org/x/tools/gopls module, whose root package is a language-server protocol (LSP) server for Go. An LSP server analyses the source code of a project and responds to requests from a wide range of editors such as VSCode and Vim, allowing them to support IDE-like functionality.
Selected commands:
cmd/goimports formats a Go program like go fmt and additionally inserts import statements for any packages required by the file after it is edited.cmd/callgraph prints the call graph of a Go program.cmd/digraph is a utility for manipulating directed graphs in textual notation.cmd/stringer generates declarations (including a String method) for “enum” types.cmd/toolstash is a utility to simplify working with multiple versions of the Go toolchain.These commands may be fetched with a command such as
go install golang.org/x/tools/cmd/goimports@latest
Selected packages:
go/ssa provides a static single-assignment form (SSA) intermediate representation (IR) for Go programs, similar to a typical compiler, for use by analysis tools.
go/packages provides a simple interface for loading, parsing, and type checking a complete Go program from source code.
go/analysis provides a framework for modular static analysis of Go programs.
go/callgraph provides call graphs of Go programs using a variety of algorithms with different trade-offs.
go/ast/inspector provides an optimized means of traversing a Go parse tree for use in analysis tools.
go/cfg provides a simple control-flow graph (CFG) for a Go function.
go/expect reads Go source files used as test inputs and interprets special comments within them as queries or assertions for testing.
go/gcexportdata and go/gccgoexportdata read and write the binary files containing type information used by the standard and gccgo compilers.
go/types/objectpath provides a stable naming scheme for named entities (“objects”) in the go/types API.
Numerous other packages provide more esoteric functionality.
