    BSON parser

    BSON parser

    BSON Parser for node and browser

    BSON parser is the core JavaScript implementation of BSON (Binary JSON), the data format used by MongoDB to represent documents on the wire and in storage. It provides encoding and decoding capabilities so JavaScript environments like Node.js and browsers can serialize rich data structures (including types not native to JSON) into the compact, efficient BSON binary representation used by MongoDB drivers and servers.

    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. ...

    Expat

    Fast streaming XML parser written in C99 with >90% test coverage

    ...Expat is a stream-oriented XML parser. This means that you register handlers with the parser before starting the parse. These handlers are called when the parser discovers the associated structures in the document being parsed. A start tag is an example of the kind of structure for which you may register handlers.

    flatted

    flatted

    A fast and minimal circular JSON parser

    ...It provides parse and stringify functions with an interface modeled after the native JSON API. During serialization, objects, arrays, and strings are flattened into indexed entries, allowing the parser to rebuild the original reference graph later. The package also includes toJSON and fromJSON helpers for classes that need recursive data to survive standard JSON workflows. It supports ESM, CommonJS, and CDN delivery, with related implementations available for PHP, Python, and Go. Flatted only handles JSON-compatible values, so specialized objects and internal runtime resources require a different serialization strategy.

    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,...

    JSON Lint

    JSON Lint

    JSON Lint for PHP

    ...Its lint method returns detailed parsing errors without decoding the input, while parse produces PHP values and throws exceptions when the document is invalid. Error messages include the relevant line, nearby text, a position marker, and the tokens expected by the parser. Optional flags can reject duplicate object keys, preserve them under generated names, or collect repeated values into arrays. The parser can also return associative arrays and accept JavaScript-style inline or block comments. UTF-8 validation detects malformed byte sequences and reports the first invalid position. The package supports a wide range of PHP releases and installs through Composer with an included jsonlint executable.

    goquery

    goquery

    A little like that j-thing, only in Go

    goquery brings a syntax and a set of features similar to jQuery to the Go language. It is based on Go's net/HTML package and the CSS Selector library Cascadia. Since the net/html parser returns nodes, and not a full-featured DOM tree, jQuery's stateful manipulation functions (like height(), css(), and detach()) have been left off. Also, because the net/HTML parser requires UTF-8 encoding, so does goquery: it is the caller's responsibility to ensure that the source document provides UTF-8 encoded HTML. See the wiki for various options to do this. ...
