    Parser for Rust source code

    Parser for Rust source code

    Parser for Rust source code

    Parser for Rust source code is a major Rust crate for parsing Rust source code (token streams) into a syntax tree (AST) that procedural macros can inspect or transform. The primary target is macro authors: you can parse TokenStreams into syn::File, syn::Item, syn::Expr, syn::Type, etc. It offers rich data structures, fine-grained parsing, span tracking (for error reporting), traversal and mutation APIs (visit, fold, visit_mut), printing back to tokens, and strong feature-gating so you only compile what you need. ...

    Modern JavaScript Cheatsheet

    Modern JavaScript Cheatsheet

    Cheatsheet for the JavaScript knowledge

    ...Each topic combines concise explanations, examples, and links for deeper study. Covered concepts include let and const, arrow functions, default parameters, destructuring, array methods, spread syntax, and property shorthand. It also explains promises, template literals, modules, classes, inheritance, this behavior, and async or await workflows. The guide distinguishes author recommendations from language rules when advice may be subjective. Community translations make the material accessible in several languages.

    scalar_objects

    scalar_objects

    Extension that adds support for method calls on primitive types in PHP

    ...It lets developers register handler classes for primitive types such as strings, arrays, integers, booleans, floats, null values, and resources. After registration, a primitive value can call methods through object-like syntax, such as calling a length method on a string. The project is mainly a proof of concept for designing cleaner primitive-type APIs in PHP. It allows API ideas to be prototyped in userland before any proposal for deeper language integration. Overall, it is most useful for PHP language experimentation, API design research, and exploring how object-style operations on scalar values could work.

    Participle

    Participle

    A parser library for Go

    ...It uses annotated Go structs to describe grammar rules and produce the parsed AST at the same time. This approach feels familiar to Go developers because it resembles the way struct tags are used for formats such as JSON. The library supports a rich grammar syntax with captures, recursive captures, grouping, alternatives, repetition, lookahead, and literal matching. It also supports custom capture behavior, union-like parser structures, and custom parsing hooks for more advanced grammars. Participle is useful when developers want readable parser definitions without switching to a separate grammar file or external parser generator.

    Training materials designed to teach JavaScript

    ...It organizes slides, exercises, and example projects into a progressive curriculum that moves from language fundamentals to tooling and best practices. Learners write code early and often, reinforcing concepts like functions, objects, modules, and asynchronous control flow. The repository encourages modern syntax and patterns while keeping examples small enough to digest in a classroom or workshop setting. It can be adapted for short bootcamps, brown-bag sessions, or self-guided study. Instructors benefit from ready-to-use outlines, while learners get runnable code and tasks that build muscle memory.

    A library to generate LaTeX expression from Python code

    latexify_py converts small, math-heavy pieces of Python code into human-readable LaTeX that mirrors the intent of the computation, not just its surface syntax. It parses Python functions and expressions into an abstract syntax tree (AST), applies symbolic rewrites for common mathematical constructs, and then emits LaTeX that compiles cleanly in standard environments. Typical use cases include turning analytical utilities—like probability mass functions, activation formulas, or recurrence relations—into equations suitable for papers, notebooks, and slide decks. ...

    Playground Cheatsheet for Python

    Playground Cheatsheet for Python

    Playground and cheatsheet for learning Python

    ...The design supports “learn by doing”: you can modify the code, run the tests, see how behavior changes, and thus internalize Python language features, idioms, and good style practices (including linting and PEP8). Because it is organized in bite-sized chunks, it’s ideal for beginners or people refreshing their Python skills who want to revisit syntax and common patterns before moving into larger frameworks or applications. It also supports usage as a reference: if you forgot how a list comprehension works or how decorators behave, you can quickly open the relevant script.
