    sebastian/diff

    sebastian/diff

    Diff implementation

    diff is a standalone PHP library for computing and rendering textual differences, widely used to display “expected vs actual” output in testing tools. It supports line-based and character/word-granular comparisons so you can get both coarse and fine-grained views of changes. Output builders can produce formats like unified or context diffs, or more human-friendly renderings suitable for terminals and HTML reports. Internally, the library splits input into hunks and manages edge cases such as whitespace-only changes and end-of-line variations. Its abstractions make it straightforward to plug custom output styles or colorizers without reimplementing diff logic. Because it’s the diff engine under PHPUnit, it has been exercised across countless projects and edge cases.

    sj.h

    sj.h

    A tiny little JSON parsing library

    sj.h is a tiny JSON parsing library written in C99 for developers who want a minimal, allocation-free way to walk through JSON data. It is intentionally small, around a few hundred lines or less depending on how it is counted, and keeps state minimal so it can fit into constrained environments. The library does not try to own every part of JSON handling; instead, it leaves number conversion and string interpretation to the user. This design gives developers direct control over memory, numeric precision, Unicode handling, and application-specific parsing behavior. It reports errors with line and column locations, which makes malformed input easier to debug despite the library’s small size. It is especially appealing for embedded tools, game engines, small utilities, and C projects that value transparency over abstraction.

    uemacs

    uemacs

    Random version of microemacs with my private modificatons

    uemacs is Linus Torvalds’ compact take on MicroEMACS, a tiny, fast, terminal-friendly text editor. The codebase prizes simplicity and portability, making it feasible to build and run on a variety of Unix-like systems without heavyweight dependencies. Its feature set is deliberately modest compared to full Emacs, favoring a quick, predictable editing experience for everyday text manipulation. The project serves as both a functional tool and an example of clean, old-school C systems programming. Because the editor is small, users can understand and modify it more easily than sprawling IDEs, which is appealing for hacking and learning. It’s not meant to compete with modern extensible editors; it exists as a minimal, dependable workhorse that starts fast and stays out of the way.

    QtContribs - Harbour Qt Projects

    QtContribs - Harbour Qt Projects

    New home to HbQt, HbIDE & HbDBU once Harbour SVN hosted contribs.

    This is the repository to host all those Harbour's contrib libraries and applications which could not comply with strict Harbour project goals but had the potentiality to march into the future. The goal is to keep this repository parallel with Harbours contrib and use the same build system which Harbour uses. This way it will be possible easily to shift any library/application from here to Harbour or vice-verse. As I am totally ignorant of Harbour's build system, it will be appreciated if someone knowledgeable take over this responsibility, which might be one-time task. Welcome to new chapter in Harbour history! Pritpal Bedi a student of software analysis & concepts

    eBus

    Publish/Subscribe, Request/Reply Messaging API for Java.

    A Java middleware API supporting broker-less, type+topic-based publish/subscribe and request/reply messaging for both intra- and inter-application, object-level communication. Broker-less: messages are transmitted directly between eBus applications. There is no message broker (i.e. server) in between. Type+topic addressing: eBus clients subscribe to a message class (type) and message topic, providing stronger typing than just topic-based subscriptions. Object-level communication: eBus delivers messages directly to client objects, not to a client process.
