Graphtage
A semantic diff utility and library for tree-like files such as JSON
Graphtage is a command-line utility and underlying library for semantically comparing and merging tree-like structures, such as JSON, XML, HTML, YAML, plist, and CSS files. Its name is a portmanteau of “graph” and “graftage”, the latter being the horticultural practice of joining two trees together such that they grow as one. Graphtage performs an analysis on an intermediate representation of the trees that is divorced from the filetypes of the input files. This means, for example, that you can diff a JSON file against a YAML file. Also, the output format can be different from the input format(s). By default, Graphtage will format the output diff in the same file format as the first input file. ... -

Go Jsonnet
This an implementation of Jsonnet in pure Go
...The repository ships both an embeddable VM for Go programs and a command-line interpreter, making it easy to integrate templating into build systems, CLIs, and services. Import paths and custom resolvers let you structure large configuration trees across directories or remote sources, while top-level arguments and external variables parameterize builds per environment. Native functions can be registered from Go to expose domain-specific helpers without forking the language. Tooling such as a formatter and linter-friendly errors encourages clean, consistent templates that scale across teams. -

Glob
glob functionality for node.js
...The library supports complex patterns such as recursive directory matching, brace expansion, and character ranges, making it suitable for build tools, CLIs, and automation scripts. node-glob is optimized for performance and reliability when traversing large file trees, and it exposes both asynchronous and synchronous APIs. Because of its maturity and flexibility, it is a foundational dependency in many JavaScript tooling ecosystems. Overall, node-glob serves as a core filesystem discovery utility for Node.js applications that rely on pattern-based file matching. -

Tree
tree is a library for working with nested data structures
...It generalizes Python’s built-in map function to operate over arbitrarily nested collections — including lists, tuples, dicts, and custom container types — while preserving their structure. This makes it particularly useful in machine learning pipelines and JAX-based workflows, where complex parameter trees or hierarchical state representations are common. The library provides efficient operations such as flatten, unflatten, and map_structure, enabling users to apply functions to all leaves of a nested structure seamlessly. Backed by a high-performance C++ core, tree is optimized for large-scale, performance-critical applications. -

php-file-iterator
FilterIterator implementation that filters files
php-file-iterator is a small library that walks directory trees and yields files matching include/exclude rules, commonly used to discover test files. It supports filtering by suffixes or prefixes (for example, “Test.php”) to keep selection deterministic. Exclusion lists help you skip vendor directories, VCS folders, or generated artifacts that would otherwise slow down tools. The iterator interface means results are streamed rather than loaded at once, which keeps memory usage modest on large codebases. ... -

Transit Format
A data interchange format
Transit is a data interchange format and set of libraries designed for reliably conveying structured values (with types) between applications written in different programming languages. The “transit-format” repository defines the specification of the format (tagging, extension, encoding rules) independent of any implementation. It builds on top of JSON and MessagePack (where possible) to reuse their performance and parsing infrastructure, but adds a tagging/extension mechanism to support... -

Files
A nicer way to handle files & folders in Swift
...The library simplifies tasks like reading, writing, moving, renaming, and deleting files while maintaining robust error handling through Swift’s try-catch mechanisms. It also supports recursive traversal of directory structures, making it easy to iterate through file trees for scripting or automation purposes. Designed primarily for Swift scripting and tooling, Files can also be embedded into applications that require file system access. Its implementation is compact and efficient, often contained within a single file, which makes it easy to integrate into projects without adding unnecessary complexity. -

Homemade Machine Learning
Python examples of popular machine learning algorithms
...Each algorithm is accompanied by mathematical explanations, visualizations (often via Jupyter notebooks), and interactive demos so you can tweak parameters, data, and observe outcomes in real time. The purpose is pedagogical: you’ll see linear regression, logistic regression, k-means clustering, neural nets, decision trees, etc., built in Python using fundamentals like NumPy and Matplotlib, not hidden behind API calls. It is well suited for learners who want to move beyond library usage to understand how algorithms operate internally—how cost functions, gradients, updates and predictions work. -

Chokidar
Minimal and efficient cross-platform file watching library
Chokidar is a solution for all the users of Node.js fs.watch who are tired of it not reporting filenames on MacOS and events at all when using editors like Sublime on MacOS. Node.js fs.watch often reports events twice, emits most changes as rename, and it does not provide an easy way to recursively watch file trees nor supports recursive watching on Linux. Same as with Node.js fs.watchFile. Therefore, Chokidar resolves these problems. Initially made for Brunch (an ultra-swift web app build tool), it is now used in Microsoft's Visual Studio Code, gulp, karma, PM2, browserify, webpack, BrowserSync, and many others. It has proven itself in production environments. ... -
