| bytes | Package bytes implements functions for the manipulation of byte slices. |
| flag | Package flag implements command-line flag parsing. |
| fmt | Package fmt implements formatted I/O with functions analogous to C's printf and scanf. |
| go/build | Package build gathers information about Go packages. |
| go/token | Package token defines constants representing the lexical tokens of the Go programming language and basic operations on tokens (printing, predicates). |
| golang.org/x/tools/go/buildutil | Package buildutil provides utilities related to the go/build package in the standard library. |
| golang.org/x/tools/go/callgraph | Package callgraph defines the call graph and various algorithms and utilities to operate on it. |
| golang.org/x/tools/go/callgraph/cha | Package cha computes the call graph of a Go program using the Class Hierarchy Analysis (CHA) algorithm. |
| golang.org/x/tools/go/callgraph/rta | This package provides Rapid Type Analysis (RTA) for Go, a fast algorithm for call graph construction and discovery of reachable code (and hence dead code) and runtime types. |
| golang.org/x/tools/go/callgraph/static | Package static computes the call graph of a Go program containing only static call edges. |
| golang.org/x/tools/go/callgraph/vta | Package vta computes the call graph of a Go program using the Variable Type Analysis (VTA) algorithm originally described in "Practical Virtual Method Call Resolution for Java," Vijay Sundaresan, Laurie Hendren, Chrislain Razafimahefa, Raja Vallée-Rai, Patrick Lam, Etienne Gagnon, and Charles Godin. |
| golang.org/x/tools/go/packages | Package packages loads Go packages for inspection and analysis. |
| golang.org/x/tools/go/ssa | Package ssa defines a representation of the elements of Go programs (packages, types, functions, variables and constants) using a static single-assignment (SSA) form intermediate representation (IR) for the bodies of functions. |
| golang.org/x/tools/go/ssa/ssautil | |
| io | Package io provides basic interfaces to I/O primitives. |
| os | Package os provides a platform-independent interface to operating system functionality. |
| runtime | Package runtime contains operations that interact with Go's runtime system, such as functions to control goroutines. |
| text/template | Package template implements data-driven templates for generating textual output. |
