go/types/objectpath: add encoder type, to amortize allocation This change adds a new encoder type with For method, that is functionally equivalent to the old For function but avoids the surprising cost of repeated calls to Scope.Names and canonicalize (now called namedMethods), both of which allocate and sorts a slice. The former canonicalize function was previously applied to interface types too, but this was costly and unnecessary as they are already sorted. The public API change will have to wait for proposal 58668 to be accepted and thus fix issue 51017; this change uses the linkname hack to expose the function to x/tools to fix a pressing bug in gopls.

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.
