Package userns provides utilities to detect whether we are currently running in a Linux user namespace.

zli is a Go library for writing command line interface programs. It includes flag parsing, color escape codes, various helpful utility functions, and makes testing fairly easy.

Package envparse is a minimal environment variable parser. It handles empty lines, comments, single quotes, double quotes, and JSON escape sequences.

Package pool contains helpers for pooling structures distinguishable by size.

Storm is a toolkit for BoltDB, providing various methods to work with it.

This is a library for manipulating geometric shapes. Unlike many geometry libraries, S2 is primarily designed to work with spherical geometry, i.e., shapes drawn on a sphere rather than on a planar 2D map. This makes it especially suitable for working with geographic data. It an alternative fork of https://github.com/golang/geo.
