gronx is cron expression parser ported from adhocore/cron-expr with task runner and daemon that supports crontab like task list file. It may be used programatically in Golang or as standalone binary instead of crond.

Package logr defines a general-purpose logging API and abstract interfaces to back that API. Packages in the Go ecosystem can depend on it, while callers can implement logging with whatever backend is appropriate.

This package provides validators and sanitizers for strings, structs and collections. It was based on validator.js.

This package provides a fast and simple way to set a value in a JSON document.

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

This package implements a functionality of creating here-documents from raw strings.

This package provides a Go library for printing numbers as Hebrew letters.

This package provides a Golang data type for ordered maps where the keys keep the order that they're added. It can be de/serialized from/to JSON.

Package linebreak wraps text at a given width, it's a translation of linear, an implementation of SMAWK algorithm.

Package strutil provides string metrics for calculating string similarity as well as other string utility functions.

Package deque provides a fast ring-buffer deque (double-ended queue) implementation for Golang.

It generalizes a queue and a stack, to efficiently add and remove items at either end with O(1) performance. Queue (FIFO) operations are supported using PushBack and PopFront. Stack (LIFO) operations are supported using PushBack and PopBack.

This package (type inf.Dec) implements a "infinite-precision" decimal arithmetic.

This package provides fixtures used by go-git.

This package implements functionality of mapping files into memory. It tries to provide a simple interface, but doesn't go out of its way to abstract away every little platform detail.

This specifically means:

• forked processes may or may not inherit mappings

• a file's timestamp may or may not be updated by writes through mappings

• specifying a size larger than the file's actual size can increase the file's size

• if the mapped file is being modified by another process while your program's running, don't expect consistent results between platforms

Package colour provides Quake-style colour formatting for Unix terminals. The package level functions can be used to write to stdout (or strings or other files). If stdout is not a terminal, colour formatting will be stripped.

Package logfmt implements utilities to marshal and unmarshal data in the logfmt format. The logfmt format records key/value pairs in a way that balances readability for humans and simplicity of computer parsing. It is most commonly used as a more human friendly alternative to JSON for structured logging.

This is a pure Go implementation of the MySQL API, compatible with golang's database/sql package.

This package provides generic implementations for Go.

errwrap is a package for Go that formalizes the pattern of wrapping errors and checking if an error contains another error.

This package implements a functionality to infer file and MIME type checking the magic numbers signature.
