gotk4 is a GTK4 bindings generator for Go. It also provides generated bindings for ATK, Cairo, GdkPixbuf, GLib, Graphene, GTK4, GTK+3 and Pango.

exif-terminator removes exif data from images (JPEG and PNG currently supported) in a streaming manner.

This packages provides functions to parse raw JPEG data into individual segments of data.

gotk3 provides Go bindings for GTK+3 and dependent projects.

Partial binding support for the following libraries is currently implemented:

• GTK 3 (3.12 and later)

• GDK 3 (3.12 and later)

• GLib 2 (2.36 and later)

• Cairo (1.10 and later)

Functions use the same names as the native C function calls, but use CamelCase. In cases where native GTK uses pointers to values to simulate multiple return values, Go's native multiple return values are used instead. Whenever a native GTK call could return an unexpected NULL pointer, an additional error is returned in the Go binding.

Package ico implements an ICO file decoder and encoder.

This Go library represents physical units like length, area, speed, and temperature as typed floating point numbers. Methods to convert between metric and US customary units of measurement are provided on each type. Additional units can be created by multiplying by const values and variables can be converted by casting.

gg is a plotting package for Go inspired by the Grammar of Graphics.

Package hyperloglog implements the HyperLogLog and HyperLogLog++ cardinality estimation algorithms. These algorithms are used for accurately estimating the cardinality of a multiset using constant memory. HyperLogLog++ has multiple improvements over HyperLogLog, with a much lower error rate for smaller cardinalities.

Package f is a Golang library implementing some basic algorithms.

Package mathutil provides utilities supplementing the standard math and math/rand packages.

S2 is a library for spherical geometry that aims to have the same robustness,flexibility, and performance as the best planar geometry libraries.

This package provides utilities for performing set operations on 1-dimensional intervals, such as time ranges.

This package provides a statistical library for Golang.

This package provides additional operations for the standard library's big.Float type, including natural logarithm, exponentiation, and power functions for arbitrary-precision floating-point numbers.

These packages provide more specialized math routines than are available in the standard Go math package. go-moremath currently focuses on statistical routines, with particular focus on high-quality implementations and APIs for non-parametric methods.

This package implements much of the decimal specification from the General Decimal Arithmetic description. This is the same specification implemented by Python’s decimal module and GCC’s decimal extension.

Package brahe defines core variable types and basic utility functions for astronomy programs using the AT-HYG (Augmented Tycho-HYG) catalog. The base file (brahe.go) defines the most widely used types in these utility functions. brahe uses the https://pkg.go.dev/gonum.org/v1/gonum/floats, Gonum floating point library for vector math.

This package implements much of the decimal specification from the General Decimal Arithmetic description. This is the same specification implemented by Python’s decimal module and GCC’s decimal extension.

This package offers overflow-checked integer arithmetic operations for int,int32, and int64. Each of the operations returns a result,bool combination. This was prompted by the need to know when to flow into higher precision types from the math.big library.

This package implements a functionality for fitting statistical model. Additional Go packages include glm for Generalized Liner Models and duration for survival analysis. All models can be fit with maximum (or quasi-maximum) likelihood estimation, with optional L1 (Lasso) or L2 (ridge) penalization.

This package provides a high-performance Uint128 type that supports standard arithmetic operations. Unlike math/big, operations on Uint128 values always produce new values instead of modifying a pointer receiver. A @codeUint128 value is therefore immutable, just like uint64 and friends.

Dstream is a package for manipulating streams of typed, multivariate data in Go. A Dstream is a dataframe-like container that holds a rectangular array of data in which the columns are variables and the rows are cases or observations.

Dstream is designed to handle large datasets, where it is not possible to load all data for all variables into memory at once. To achieve this, Dstream utilizes a chunked, column-based storage format. A chunk contains the data for a contiguous block of rows. The data are stored by variable (column-wise) in typed Go slices. Only one chunk of the Dstream is held in memory at one time.

This package provides a moving average implementation for Go.

This package provides a Topological sort lib. Sorting and pruning of DAG graphs.
