    jq

    jq

    Lightweight and flexible command-line JSON processor

    jq is like sed for JSON data - you can use it to slice, filter, map and transform structured data with the same ease that sed, awk, grep and friends let you play with text. jq is written in portable C, and it has zero runtime dependencies. You can download a single binary, scp it to a far away machine of the same type, and expect it to work. jq can mangle the data format that you have into the one that you want with very little effort, and the program to do so is often shorter and simpler than you'd expect. Data in jq is represented as streams of JSON values - every jq expression runs for each value in its input stream, and can produce any number of values to its output stream. jq filters run on a stream of JSON data. The input to jq is parsed as a sequence of whitespace-separated JSON values which are passed through the provided filter one at a time. The output(s) of the filter are written to standard out, again as a sequence of whitespace-separated JSON data.

    geckodriver

    geckodriver

    WebDriver for Firefox

    geckodriver is an implementation of WebDriver, and WebDriver can be used for widely different purposes. How you invoke geckodriver largely depends on your use case. If you are using geckodriver through Selenium, you must ensure that you have version 3.11 or greater. Because geckodriver implements the W3C WebDriver standard and not the same Selenium wire protocol older drivers are using, you may experience incompatibilities and migration problems when making the switch from FirefoxDriver to geckodriver. Generally speaking, Selenium 3 enabled geckodriver as the default WebDriver implementation for Firefox. With the release of Firefox 47, FirefoxDriver had to be discontinued for its lack of support for the new multi-processing architecture in Gecko. Since geckodriver is a separate HTTP server that is a complete remote end implementation of WebDriver, it is possible to avoid using the Selenium remote server if you have no requirements to distribute processes across a matrix of systems.

    mPDF

    mPDF

    PHP library generating PDF files from UTF-8 encoded HTML

    mPDF is a PHP library that generates PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files ‘on-the-fly’ from his website, handling different languages. It is slower than the original scripts e.g. HTML2FPDF and produces larger files when using Unicode fonts, but support for CSS styles etc. and has been much enhanced. Supports almost all languages including RTL (Arabic and Hebrew), and CJK (Chinese-Japanese-Korean). Nested block-level elements (e.g. P, DIV) including margins, borders, padding, line height, background colors, etc. Right-to-left languages are supported, with automatic detection of RTL characters within a document. Transposes tables, lists, text justification, and table cell alignment, as well as a full-text reversal for RTL characters. Automatically detects non-RTL characters and displays these in the original order.

    TinyTeX releases

    TinyTeX releases

    Windows/macOS/Linux binaries and installation methods of TinyTeX

    A lightweight, cross-platform, portable, and easy-to-maintain LaTeX distribution based on TeX Live. TinyTeX is a custom LaTeX distribution based on TeX Live that is small in size but functions well in most cases, especially for R users. If you run into the problem of missing LaTeX packages, it should be super clear to you what you need to do (in fact, R users won’t need to do anything). You only install LaTeX packages you actually need. Currently, TinyTeX works best for R users. Other users can use it, too, it is just that missing LaTeX packages won’t be automatically installed, and you need to install them manually. Or you can go to the extreme to install all packages (see FAQ 3 for how), but remember there are thousands of them. Installing or running TinyTeX does not require admin privileges, which means you no longer need sudo or your IT. You can even run TinyTeX from a Flash drive.

    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.
