This package provides a simple scheduler which, can run a function at a given time, in a given duration, or repeatedly at a given interval.

Suture provides Erlang-ish supervisor trees for Go. "Supervisor trees" -> "sutree" -> "suture" -> holds your code together when it's trying to die.

It is intended to deal gracefully with the real failure cases that can occur with supervision trees (such as burning all your CPU time endlessly restarting dead services), while also making no unnecessary demands on the "service" code, and providing hooks to perform adequate logging with in a production environment

This package provides an implementation for the goverter feature wrapErrorsUsing.

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.

Bubble Tea is a Go framework based on The Elm Architecture. It is well-suited for simple and complex terminal applications, either inline, full-window, or a mix of both.

This package provides a High Performance, Feature-Rich Idiomatic codec/encoding library for msgpack, JSON.

Supported Serialization formats are:

• msgpack: https://github.com/msgpack/msgpack

• json: http://json.org http://tools.ietf.org/html/rfc7159

This package provides fast methods for formatting JSON for human readability, or to compact JSON for smaller payloads.

EditorConfig makes it easy to maintain the correct coding style when switching between different text editors and between different projects. It maintains a file format and plugins for various text editors which allow this file format to be read and used by those editors.

This package implements ULID as specified in https://github.com/ulid/spec.

Features of ULID:

• 128-bit compatibility with UUID

• 1.21e+24 unique ULIDs per millisecond

• lexicographically sortable

• canonically encoded as a 26 character string, as opposed to the 36 character UUID

• uses Crockford's base32 for better efficiency and readability (5 bits per character)

• case insensitive

• no special characters (URL safe)

• monotonic sort order (correctly detects and handles the same millisecond)

Package colorprofile provides a way to downsample ANSI escape sequence colors and styles automatically based on output, environment variables, and Terminfo databases.

Go-md2man is a Go program that converts markdown to roff for the purpose of building man pages. This package provides a command line interface (CLI) tool.

This package implements a simple XML 1.0 parser that understands XML name spaces, along with extended support for control characters.

This package provides a set of conversion utilities to migrate between different versioned Go structs.

go-semver is a semantic versioning library for Go. It lets you parse and compare two semantic version strings.

This package implements a similar functionality like standard sync.WaitGroup

JWW is primarily a wrapper around the standard log library. It provides a few advantages over using the standard log library alone.

• ready to go out of the box

• one library for both printing to the terminal and logging (to files)

• really easy to log to either a temp file or a file you specify

This package implements sysconf and provides the associated SC_* constants to query system configuration values at run time.
