bufio | Package bufio implements buffered I/O. It wraps an io.Reader or io.Writer object, creating another object (Reader or Writer) that also implements the interface but provides buffering and some help for textual I/O. |
bytes | Package bytes implements functions for the manipulation of byte slices. |
errors | Package errors implements functions to manipulate errors. |
fmt | Package fmt implements formatted I/O with functions analogous to C's printf and scanf. |
go/ast | Package ast declares the types used to represent syntax trees for Go packages. |
go/build/constraint | Package constraint implements parsing and evaluation of build constraint lines. |
go/doc | Package doc extracts source code documentation from a Go AST. |
go/parser | Package parser implements a parser for Go source files. |
go/token | Package token defines constants representing the lexical tokens of the Go programming language and basic operations on tokens (printing, predicates). |
internal/buildcfg | Package buildcfg provides access to the build configuration described by the current environment. |
internal/goroot | |
internal/goversion | |
io | Package io provides basic interfaces to I/O primitives. |
io/fs | Package fs defines basic interfaces to a file system. |
os | Package os provides a platform-independent interface to operating system functionality. |
os/exec | Package exec runs external commands. |
path | Package path implements utility routines for manipulating slash-separated paths. |
path/filepath | Package filepath implements utility routines for manipulating filename paths in a way compatible with the target operating system-defined file paths. |
runtime | Package runtime contains operations that interact with Go's runtime system, such as functions to control goroutines. |
sort | Package sort provides primitives for sorting slices and user-defined collections. |
strconv | Package strconv implements conversions to and from string representations of basic data types. |
strings | Package strings implements simple functions to manipulate UTF-8 encoded strings. |
unicode | Package unicode provides data and functions to test some properties of Unicode code points. |
unicode/utf8 | Package utf8 implements functions and constants to support text encoded in UTF-8. |
