| 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. |
| context | Package context defines the Context type, which carries deadlines, cancellation signals, and other request-scoped values across API boundaries and between processes. |
| fmt | Package fmt implements formatted I/O with functions analogous to C's printf and scanf. |
| github.com/google/shlex | Package shlex implements a simple lexer which splits input in to tokens using shell-style rules for quoting and commenting. |
| github.com/moby/buildkit/util/contentutil | |
| github.com/pkg/errors | Package errors provides simple error handling primitives. |
| github.com/sirupsen/logrus | Package logrus is a structured logger for Go, completely API compatible with the standard library logger. |
| github.com/stretchr/testify/assert | Package assert provides a set of comprehensive testing tools for use with the normal Go testing system. |
| github.com/stretchr/testify/require | Package require implements the same assertions as the `assert` package but stops test execution when a test fails. |
| golang.org/x/sync/errgroup | Package errgroup provides synchronization, error propagation, and Context cancelation for groups of goroutines working on subtasks of a common task. |
| io | Package io provides basic interfaces to I/O primitives. |
| io/ioutil | Package ioutil implements some I/O utility functions. |
| net | Package net provides a portable interface for network I/O, including TCP/IP, UDP, domain name resolution, and Unix domain sockets. |
| os | Package os provides a platform-independent interface to operating system functionality. |
| os/exec | Package exec runs external commands. |
| path/filepath | Package filepath implements utility routines for manipulating filename paths in a way compatible with the target operating system-defined file paths. |
| reflect | Package reflect implements run-time reflection, allowing a program to manipulate objects with arbitrary types. |
| regexp | Package regexp implements regular expression search. |
| 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. |
| strings | Package strings implements simple functions to manipulate UTF-8 encoded strings. |
| sync | Package sync provides basic synchronization primitives such as mutual exclusion locks. |
| syscall | Package syscall contains an interface to the low-level operating system primitives. |
| testing | Package testing provides support for automated testing of Go packages. |
| time | Package time provides functionality for measuring and displaying time. |
