This package provides a lightweight string parsing and representation of angles.

This package provides additional functionality for working with missing values in Julia.

This package provides a Julia interface to the Matplotlib plotting library from Python, and specifically to the matplotlib.pyplot module. PyPlot uses the Julia PyCall package to call Matplotlib directly from Julia with little or no overhead (arrays are passed without making a copy).

This package provides a method to ensure that arguments to a function conform to a specification.

The SortingAlgorithms package provides three sorting algorithms that can be used with Julia's standard sorting API: heapsort, timsort and radixsort.

A Julia package for evaluating distances(metrics) between vectors. This package also provides optimized functions to compute column-wise and pairwise distances, which are often substantially faster than a straightforward loop implementation.

Optim.jl is a package for univariate and multivariate optimization of functions.

This package provides zlib codecs for TranscodingStreams.jl.

This package provides an implementation of shifted arrays for Julia.

The purpose of this package is to allow Julia function calls to be temporarily overloaded for the purpose of testing.

Crayons is a package that makes it simple to write strings in different colors and styles to terminals. It supports the 16 system colors, both the 256 color and 24 bit true color extensions, and the different text styles available to terminals.

FixedPointNumbers.jl implements fixed-point number types for Julia. A fixed-point number represents a fractional, or non-integral, number. In contrast with the more widely known floating-point numbers, with fixed-point numbers the decimal point doesn't "float": fixed-point numbers are effectively integers that are interpreted as being scaled by a constant factor. Consequently, they have a fixed number of digits (bits) after the decimal (radix) point.

This package implements handy macros @recipe and @series which will define a custom transformation and attach attributes for user types. Its design is an attempt to simplify and generalize the summary and display of types and data from external packages. With this package it is possible to describe visualization routines that can be used as components in more complex visualizations.

This implements the notation .. for indexing arrays. It's similar to the Python ... in that it means "all of the columns before (or after)".

This package provides definitions for most of the primary types and functions in StaticArrays.jl. This enables downstream packages to implement new methods on these types without depending on the entirety of StaticArrays.jl.

This package provides several functions to manipulate strings with ANSI escape sequences.

This package provides SentinelArrayT that wraps an AbstractArray of type T, and accepts a sentinel and value argument.

This package provides primitive differentiation rules that can be composed via various formulations of the chain rule. Using DiffRules, new differentiation rules can defined, query whether or not a given rule exists, and symbolically apply rules to simple Julia expressions.

This package supports representing banded matrices by only the entries on the bands.

This package provides tools for working with categorical variables, both with unordered (nominal variables) and ordered categories (ordinal variables), optionally with missing values.

HTTP.jl is a Julia library for HTTP Messages, implementing both a client and a server.

This package calculates approximate derivatives numerically using finite difference.

This package allows programmers to explicitly SIMD-vectorize their Julia code. By exposing SIMD vector types and corresponding operations, the programmer can explicitly vectorize their code. While this does not guarantee that the generated machine code is efficient, it relieves the compiler from determining whether it is legal to vectorize the code, deciding whether it is beneficial to do so, and rearranging the code to synthesize vector instructions.

Millboard.jl provides a library for getting data in a tablized format to arrange into rows and columns of cells.
