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. |
cmd/go/internal/cfg | Package cfg holds configuration shared by multiple parts of the go command. |
cmd/go/internal/fsys | Package fsys implements a virtual file system that the go command uses to read source file trees. |
errors | Package errors implements functions to manipulate errors. |
fmt | Package fmt implements formatted I/O with functions analogous to C's printf and scanf. |
io | Package io provides basic interfaces to I/O primitives. |
io/fs | Package fs defines basic interfaces to a file system. |
path/filepath | Package filepath implements utility routines for manipulating filename paths in a way compatible with the target operating system-defined file paths. |
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. |
sync | Package sync provides basic synchronization primitives such as mutual exclusion locks. |
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. |
