internal/lsp/cache: derive workspace packages from metadata Now that we preserve stale metadata, we can derive workspace packages entirely from known metadata and files. This consolidates the logic to compute workspace packages into a single location, which can be invoked whenever metadata changes (via load or invalidation in clone). Additionally: - Precompute 'HasWorkspaceFiles' when loading metadata. This value should never change for a given Metadata, and our view.contains func is actually quite slow due to evaluating symlinks. - Track 'PkgFilesChanged' on KnownMetadata, since we don't include packages whose package name has changed in our workspace. Also introduce a few debug helpers, so that we can leave some instrumentation in critical functions.

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.
