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
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.
cmd/goimportsformats a Go program like
go fmtand additionally inserts import statements for any packages required by the file after it is edited.
cmd/callgraphprints the call graph of a Go program.
cmd/digraphis a utility for manipulating directed graphs in textual notation.
cmd/stringergenerates declarations (including a
Stringmethod) for "enum" types.
cmd/toolstashis 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
go/ssaprovides a static single-assignment form (SSA) intermediate representation (IR) for Go programs, similar to a typical compiler, for use by analysis tools.
go/packagesprovides a simple interface for loading, parsing, and type checking a complete Go program from source code.
go/analysisprovides a framework for modular static analysis of Go programs.
go/callgraphprovides call graphs of Go programs using a variety of algorithms with different trade-offs.
go/ast/inspectorprovides an optimized means of traversing a Go parse tree for use in analysis tools.
go/cfgprovides a simple control-flow graph (CFG) for a Go function.
go/expectreads Go source files used as test inputs and interprets special comments within them as queries or assertions for testing.
go/gccgoexportdataread and write the binary files containing type information used by the standard and
go/types/objectpathprovides a stable naming scheme for named entities ("objects") in the
Numerous other packages provide more esoteric functionality.
