Peco is an interactive text filter and fuzzy finder for the terminal. It serves as a terminal user interface selection tool that filters standard input in real-time using fuzzy matching and regular expressions. The tool preserves and renders ANSI color escape sequences from piped input streams while performing matching logic on plain-text versions. It supports multi-stage filtering, allowing users to freeze result sets to create a new base for subsequent refinements. Capability areas include advanced search filtering with negative matching, multi-item selection, and the ability to pipe selec

This project is a collection of Go libraries designed to reduce the size of multiple web formats while preserving functional integrity. It serves as a high-performance text processor and multi-format asset compressor for shrinking HTML, CSS, JavaScript, JSON, SVG, and XML files by removing redundant characters. The tool is designed for both static batch processing and real-time use. It includes middleware capabilities to intercept and minify web responses on the fly based on MIME types or file extensions, allowing for content compression during active data streams. The processing suite cover

Get the real length of a string - by correctly counting astral symbols and ignoring ansi escape codes

This project is a Unicode text repair tool and mojibake correction library designed to fix encoding glitches and restore original characters from mangled strings. It functions as a text encoding detector and a Unicode normalization tool to resolve issues where text has been incorrectly decoded. The library specializes in reversing multi-layered encoding errors and repairing complex mojibake patterns. It includes capabilities for detecting lossy encoding sequences, guessing byte encodings, and decoding non-standard UTF-8 variants. The toolset covers a broad range of text cleaning and normaliz

i18next is a JavaScript localization library and internationalization framework used to translate application text into multiple languages. It functions as a dynamic translation manager that handles translation resources, language detection, and the mapping of unique keys to localized strings. The system features a pluralization and interpolation engine that applies language-specific grammatical rules for numeric counts and injects dynamic variables into strings. It utilizes a plugin-based backend architecture to load and cache translation namespaces from various sources, including remote ser

This project is a UUID generation library providing a standards-compliant implementation of RFC 4122. It serves as a tool for creating and validating universally unique identifiers across multiple versions to ensure global uniqueness and prevent data collisions. The library supports several generation methods, including random-based entropy, timestamp sequencing, and namespace-based hashing. It also includes utilities for identifier validation, parsing, and converting identifiers between hexadecimal string representations and binary byte arrays. A command line utility is included for the man

xid is a distributed unique identifier library designed to generate compact, globally unique, and k-sortable identifiers. It functions as a stateless generator that creates identifiers without requiring a central coordinator or network synchronization between instances. The project converts binary identifiers into human-readable, case-insensitive Base32 strings, making the output suitable for use in URLs and web applications. It ensures uniqueness across different processes and hosts by combining high-resolution timestamps with machine identifiers. These identifiers are designed for use as d

Markdig is a high-performance Markdown processor for .NET applications that converts Markdown text into HTML or other target formats. It is a CommonMark compliant parser and extensible engine that can transform Markdown into a searchable and manipulatable abstract syntax tree. The library provides a framework for adding custom syntax and rendering logic through a modular pipeline of parsers and renderers. It supports native ahead-of-time compilation and trimming to minimize binary size. Capabilities include the generation of structured HTML with custom attributes and styling, the extraction

Presto is a distributed SQL query engine designed for high-performance analytical processing across heterogeneous data sources. It functions as a data federation platform and massively parallel processing engine, allowing users to execute interactive queries against diverse storage systems without requiring data migration. By mapping remote metadata and structures to a unified relational namespace, it enables seamless cross-platform analysis through a standard SQL interface. The engine distinguishes itself through a pluggable connector architecture and a shared-nothing distributed processing

This project provides the official specification for ULIDs, which are 128-bit identifiers that combine a millisecond-precision timestamp and random data. These identifiers are designed to be lexicographically sortable, ensuring that they maintain a strict chronological sequence for database indexing and time-based sorting. The specification defines a standard for binary-to-string serialization using a Crockford-inspired Base32 alphabet. This encoding is intended to produce human-readable strings while excluding ambiguous characters to prevent transcription errors. The technical standards cov

PostgREST is a tool that automatically transforms a PostgreSQL database schema into a production-ready RESTful API. It serves as a database access layer and query engine that maps HTTP requests directly to SQL queries, providing a low-code interface for executing create, read, update, and delete operations without requiring manual boilerplate code. The project distinguishes itself by using schema-driven API generation and metadata-based discovery to expose database tables as navigable resources. It extends standard CRUD capabilities through the execution of custom and templated SQL, a plugin-

Lucia is an authentication library that provides session management, OAuth integration, and password-based login for web applications. It creates and validates server-side sessions using cryptographically random tokens stored in HttpOnly, Secure, SameSite=Lax cookies, with constant-time token comparison to prevent timing side-channel attacks. The library supports authentication through email and password, GitHub OAuth, Google OAuth, and passkey-based sign-in.
