JSON for Modern C++
JSON that's part of C++
This is JSON for C++, a JSON library unlike any other that's packed with plenty of great features. While there may be dozens of JSON libraries out there, JSON for C++ stands out with a focus on three things: an intuitive syntax, trivial integration and serious testing. Using the operator magic of modern C++, this library makes JSON feel like a first class data type. With trivial integration, the entire code is made up of a single header file json.hpp, no dependencies, no complex build system... -

Unitful.jl
Physical quantities with arbitrary units
Unitful is a Julia package for physical units. We want to support not only SI units but also any other unit system. We also want to minimize or in some cases eliminate the run-time penalty of units. There should be facilities for dimensional analysis. All of this should integrate easily with the usual mathematical operations and collections that are found in Julia base. -

Less.js
Less, the dynamic stylesheet language
...If it is possible, mathematical operations take units into account and convert numbers before adding, subtracting or comparing them. The result has leftmost explicitly stated unit type. If the conversion is impossible or not meaningful, units are ignored. With Less you can transform colors, manipulate strings and do maths. -

pretty-ms
Convert milliseconds to a human readable string
pretty-ms is a JavaScript utility for converting millisecond values into compact, human-readable durations. It accepts both numbers and BigInt values and automatically breaks durations into appropriate time units. Developers can choose concise output, full unit names, or digital-clock-style colon notation. Precision controls determine how seconds and milliseconds are rounded and displayed. The package can expose microseconds and nanoseconds for sub-millisecond values and can represent... -

libCIGI
C++ Library for the Common Image Generator Interface
...Packet processing is kept simple and a couple of simple helper functions / classes are provided in CIGIGeneric.h and some other headers to support this. Helpers are provided for version interpretation and conversion of packet parameters to text. Testing is supported using the boost test framework to develop unit tests for each of the packets. Because the library is header-only it can easily support many platforms / compilers but this has not yet been tested. Note: Currently the use of bitfields in the library may cause erroneous use in some compilers. -

ms
Tiny millisecond conversion utility
Use this package to easily convert various time formats to milliseconds. Works both in Node.js and in the browser. If a number is supplied to ms, a string with a unit is returned. If a string that contains the number is supplied, it returns it as a number (e.g.: it returns 100 for '100'). If you pass a string with a number and a valid unit, the number of equivalent milliseconds is returned. For added safety, we're using Template Literal Types (added in TypeScript 4.1). This ensures that you... -

iLib
The most comprehensive library of Javascript i18n classes available
Note: development has been moved over to github! Please see https://github.com/iLib-js/iLib "I18N" means way more than just translation. Other libraries claim to be an i18n solution when translation and string formatting is really all they offer. Yes, iLib has classes that do translation too, but there is also much, much more. From date formatting to name parsing to phone number handling to collation, iLib has classes that do it. And, it has the ability to support thousands of possible... -
