gawk libraries for XML, PostgreSQL,...
Dynamically loaded extension libraries for GNU AWK
The gawkextlib project provides several extension libraries for gawk (GNU AWK), as well as libgawkextlib containing some APIs that are useful for building gawk extension libraries. These libraries enable gawk to process XML data, interact with a PostgreSQL database, use the GD graphics library, and perform unlimited precision MPFR calculations. These extensions work with GNU AWK version 4.1.1 or later. We have created a framework for packaging gawk extensions, and we welcome further contributions. Recent additions include haru, redis, and select for I/O multiplexing. -

xlsx is a library to simplify reading and writing the XML format used by recent version of Microsoft Excel in Go programs. Version 3.0.0 introduces some more breaking changes in the API. All methods that can return an `xlsx.File` struct now accept zero, one or many `xlsx.FileOption` functions as their final arguments. These can be used to modify the behavior of the resultant struct, in particular they replace the `…WithRowLimit` variants of those methods with the result of calling `xlsx.RowLimit` and they add the ability to define a custom backing store for the spreadsheet data to be held in whilst processing. The full API docs can be viewed using go’s built in documentation tool. -

For example, JSONPlaceholder is an online fake API powered by JSON Server and running on Heroku. If you make POST, PUT, PATCH or DELETE requests, changes will be automatically and safely saved to db.json using lowdb. You can use JSON Server to serve your HTML, JS and CSS, simply create a ./public directory or use --static to set a different static files directory. There are many ways to set up SSL in development. One simple way is to use hotel. -

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 required. It's been heavily unit-tested covering 100% of the code, and follows the Core Infrastructure Initiative (CII) best practices to ensure the highest quality at all times. Among its many features are JSON pointers, JSON patches, Iterators, SAX parsing and various container operations. -

Jbuilder
Generate JSON objects with a Builder-style DSL
Jbuilder gives you a simple DSL for declaring JSON structures that beats manipulating giant hash structures. This is particularly helpful when the generation process is fraught with conditionals and loops. You can either use Jbuilder stand-alone or directly as an ActionView template language. When required in Rails, you can create views à la show.json.jbuilder (the json is already yielded). Fragment caching is supported, it uses Rails.cache and works like caching in HTML templates. If your collection cache depends on multiple sources (try to avoid this to keep things simple), you can name all these dependencies as part of a block that returns an array. -

Python ADB
Python ADB + Fastboot implementation
python-adb provides a pure-Python implementation of the Android Debug Bridge protocol so you can script Android devices without depending on the platform adb binary. It exposes high-level helpers for device discovery, shell commands, file push/pull, port forwarding, and log collection, making it easy to build automation around phones and emulators. Under the hood it speaks the ADB protocol directly and can connect via USB or over TCP, which is useful for lab setups and headless servers. Because it’s Python, you can compose device actions with your favorite testing, scraping, or data-collection libraries in one process. The project also includes utilities for robust connection handling and timeouts so flaky USB links don’t derail long runs. It’s well-suited to CI test farms, large-scale telemetry, and custom device control workflows. -
