This subrepository holds the source for various packages and tools that support the Go programming language.

Reports unused function parameters and results in your code.

This package holds the transition packages for the new Go 1.13 error values.

Deprecated: A tool that suggests interfaces is prone to bad suggestions, so its usefulness in real code is limited. This tool will remain available as a proof of concept, and for others to examine and learn from.

This repository holds packages for writing tools that work directly with Go module mechanics. That is, it is for direct manipulation of Go modules themselves.

The specific case of loading packages should still be done by invoking the go command, which remains the single point of truth for package loading algorithms.

reflect api that avoids runtime reflect.Value cost

This repository holds supplemental Go packages for low-level interactions with the operating system.

This package provides a flexible DNS proxy, with support for modern encrypted DNS protocols such as DNSCrypt v2, DNS-over-HTTPS, Anonymized DNSCrypt and ODoH (Oblivious DoH).

Enforce a stricter format than gofmt, while being backwards compatible. That is, gofumpt is happy with a subset of the formats that gofmt is happy with.

This package is intended to be a more powerful and safer alternative to reflect.DeepEqual for comparing whether two values are semantically equal.

because sync.Map is only available in go 1.9, we can use concurrent.Map to make code portable

This package provides supplemental Go libraries for text processing.

Package xxhash implements the 64-bit variant of xxHash (XXH64) as described at http://cyan4973.github.io/xxHash/.

Staticcheck is a state of the art linter for the . Using static analysis, it finds bugs and performance issues, offers simplifications, and enforces style rules.

Package lint defines common interfaces for Go code checkers.

Package jsoniter implements encoding and decoding of JSON as defined in RFC 4627 and provides interfaces with identical syntax of standard lib encoding/json. Converting from encoding/json to jsoniter is no more than replacing the package with jsoniter and variable type declarations (if any). jsoniter interfaces gives 100% compatibility with code using standard lib.

Kingpin is a fluent-style, type-safe command-line parser. It supports flags, nested commands, and positional arguments.

Project-rg (project-rg.el) allow run ripgrep with Project (project.el).

This package provides a minor mode that (sometimes) makes Emacs start slightly faster.

This package enables you to step through historic versions of files under Git version control from within Emacs.
