Puddle is a tiny generic resource pool library hat uses the standard context library to signal cancellation of acquires. It is designed to contain the minimum functionality required for a resource pool. It can be used directly or it can be used as the base for a domain specific resource pool. For example, a database connection pool may use puddle internally and implement health checks and keep-alive behavior without needing to implement any concurrent code of its own.

This package provides an ANSI color package to output colorized or SGR defined output to the standard output.

This is a development helper program that generates a Golang interface by inspecting the structure methods of an existing .go file. The primary use case is to generate interfaces for gomock, so that gomock can generate mocks from those interfaces. This package provides a command line interface (CLI) tool.

Package templatecheck checks Go templates for problems. It can detect many errors that are normally caught only during execution. Use templatecheck in tests to find template errors early, and along template execution paths that might only rarely be reached.

Package optparse parses command line arguments very similarly to GNU getopt_long(). It supports long options and optional arguments, but does not permute arguments. It is intended as a replacement for Go's flag package.
