Awkward Array is a library for nested, variable-sized data, including
arbitrary-length lists, records, mixed types, and missing data, using
NumPy-like idioms.

Arrays are dynamically typed, but operations on them are compiled and fast.
Their behavior coincides with NumPy when array dimensions are regular and
generalizes when they're not.

Folium is a python library to make beautiful maps with Leafletsjs. Folium
builds on the data wrangling strengths of the Python ecosystem and the mapping
strengths of the Leaflet.js library. Manipulate your data in Python, then
visualize it in a Leaflet map via folium.

healpy is a Python package to handle pixelated data on the sphere. It is based
on the Hierarchical Equal Area isoLatitude Pixelization (HEALPix) scheme and
bundles the HEALPix C++ library.

healpy provides utilities to:
* convert between sky coordinates and pixel indices in HEALPix nested and ring schemes
* find pixels within a disk, a polygon or a strip in the sky
* apply coordinate transformations between Galactic, Ecliptic and Equatorial reference frames
* apply custom rotations either to vectors or full maps
* read and write HEALPix maps to disk in FITS format
* upgrade and downgrade the resolution of existing HEALPix maps
* visualize maps in Mollweide, Gnomonic and Cartographic projections
* transform maps to Spherical Harmonics space and back using multi-threaded C++ routines
* compute Auto and Cross Power Spectra from maps and create map realizations from spectra

Panel is a Python library that lets you create custom interactive web apps and
dashboards by connecting user-defined widgets to plots, images, tables, or
text.

PyGiNaC is a Python package that provides an interface to the C++ library
GiNaC, which is an open framework for symbolic computation within C++. PyGiNaC
is implemented with the help of the Boost.Python library.

mpi plugin for pytest to collect information from openmpi-based tests.

A common package to provide example files (*e.g*. ROOT) for testing and
developing packages against. The sample of files is representative of typical
files found "in the wild".

In addition to including some root files directly, this package adds some
simple helper methods to get larger files from common open-access data
repositories.

Tinyarrays are similar to NumPy arrays, but optimized for small sizes.
Tinyarrays support mathematical operations like element-wise addition
and matrix multiplication. Tinyarrays can be used as dictionary keys
because they are hashable and immutable. Tinyarrays are useful if you
need many small arrays of numbers, and cannot combine them into a few
large ones. Common operations on very small arrays are faster than
with NumPy, and less memory is used to store them.

Uproot is a reader and a writer of the ROOT file format using only Python and
Numpy. Unlike the standard C++ ROOT implementation, Uproot is only an I/O
library, primarily intended to stream data into machine learning libraries in
Python. It uses Numpy to cast blocks of data from the ROOT file as Numpy
arrays.

Armadillo is a C++ linear algebra library (matrix maths) aiming towards a good balance between speed and ease of use. Integer, floating point and complex numbers are supported, as well as a subset of trigonometric and statistics functions. Various matrix decompositions are provided through optional integration with LAPACK and ATLAS libraries. A delayed evaluation approach is employed (during compile time) to combine several operations into one and reduce (or eliminate) the need for temporaries. This is accomplished through recursive templates and template meta-programming. This library is useful if C++ has been decided as the language of choice (due to speed and/or integration capabilities), rather than another language like Matlab or Octave.

Blitz++ is a C++ template class library that provides high-performance
multidimensional array containers for scientific computing.

CastXML is a C-family abstract syntax tree XML output tool.

HEALPix is a Hierarchical, Equal Area, and iso-Latitude Pixelation of the
sphere designed to support efficiently (1) local operations on the pixel set,
(2) a hierarchical tree structure for multi-resolution applications, and (3)
the global Fast Spherical Harmonic transform.

libLASi is a library written by Larry Siden that provides a C++ stream output interface for creating Postscript documents that can contain characters from any of the scripts and symbol blocks supported in Unicode and by Owen Taylor's Pango layout engine. The library accomodates right-to-left scripts such as Arabic and Hebrew as easily as left-to-right scripts. Indic and Indic-derived Complex Text Layout (CTL) scripts, such as Devanagari, Thai, Lao, and Tibetan are supported to the extent provided by Pango and by the OpenType fonts installed on your system. All of this is provided without need for any special configuration or layout calculation on the programmer's part.

Although the capability to produce Unicode-based multilingual Postscript documents exists in large Open Source application framework libraries such as GTK+, QT, and KDE, libLASi was designed for projects which require the ability to produce Postscript independent of any one application framework.

libsharp is a code library for spherical harmonic transforms (SHTs) with
features including MPI support for distributed memory systems and SHTs of
fields with arbitrary spin, supporting new developments in CPU instruction sets
like the Advanced Vector Extensions (AVX) or fused multiply-accumulate (FMA)
instructions.

A C++ library with classes for forking external processes and asynchronous reading from streams. It takes away the burden of all subtleties involving the Unix fork call. The asynchronous read facility enables one to read on multiple input streams at the same time, without losing any of the standard C++ stream facilities.
There are also several small additional programs bundled with modglue, such as a program to add readline capability to any command line program. Moreover, the modglue library extends the idea of standard Unix pipes by providing a general framework for the creation of new processes with more than just the standard stdin/stdout/stderr pipes.

Parallel Tasking Library (PTL) is a lightweight C++11 multithreading tasking
system featuring thread-pool, task-groups, and lock-free task queue.
