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/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.

subdir):" in the subject line, so it is easy to find.
JavaScript and CSS Formatting
This repository uses prettier to format JS and CSS files.
The version of prettier used is 1.18.2.
It is encouraged that all JS and CSS code be run through this before submitting
a change. However, it is not a strict requirement enforced by CI.
