SDL_mixer is a multi-channel audio mixer library for SDL. It supports any number of simultaneously playing channels of 16 bit stereo audio, plus a single channel of music. Supported formats include FLAC, MOD, MIDI, Ogg Vorbis, and MP3.

This package supports two MIDI backends, selectable at runtime. To use the newer fluidsynth library, install a soundfont such as fluid-3 and specify it using the SDL_SOUNDFONTS environment variable. For the legacy timidity backend, install a patch set such as freepats and set the path to the configuration file with TIMIDITY_CFG.

Simple DirectMedia Layer is a cross-platform development library designed to provide low level access to audio, keyboard, mouse, joystick, and graphics hardware. This package is a compatibility layer; it provides a binary and source compatible API for programs written against SDL 1.2, but it uses SDL 2.0 behind the scenes.

A fork of SDL mixer with the goal of fixing various issues and supporting more audio formats.

SDL_ttf is a TrueType font rendering library for SDL.

Simple DirectMedia Layer is a cross-platform development library designed to provide low level access to audio, keyboard, mouse, joystick, and graphics hardware. This package is a compatibility layer; it provides a binary and source compatible API for programs written against SDL2, but it uses SDL3 behind the scenes.

SDL_image is an image file loading library for SDL that supports the following formats: BMP, GIF, JPEG, LBM, PCX, PNG, PNM, TGA, TIFF, WEBP, XCF, XPM, and XV.

SDL_gfx provides graphics drawing primitives, rotozoom and other supporting functions for SDL.

This package provides a community sourced database of game controller mappings intended for the use with SDL2's game controller functionality.

This package provides a library to load TrueType (.ttf) font files with Simple Directmedia Layer.

Ugrep is a ultra fast searcher of file systems, text and binary files, source code, archives, compressed files, documents, and more.

While still being compatible with the standard GNU/BSD grep command-line options, ugrep supports fuzzy search as well as structured and (adjustable) colored output, piped through "less" for pagination. An interactive query UI allows refinement and has a built-in help (press F1). Ugrep implements multi-threaded and other techniques to speed up search, pattern-matching and decompression. Many pre-defined regexps ease searching e.g. C typdefs or XML attributes. Results can be output in several structured or self-defined formats.

Hyper Estraier can be used to integrate full-text search into applications, using either the provided command line and CGI interfaces, or a C API.

Omega is a search application built on Xapian. It provides indexers and a CGI web search frontend.

Tocc is a tag-based file management system. This package contains the command line tool for interacting with libtocc.

Dataparksearch is a full featured web search engine. It has support for HTTP, HTTPS, ftp (passive mode), NNTP and news URL schemes, and other URL schemes with external parsers. It can tweak URLs with session IDs and other weird formats, including some JavaScript link decoding. Options to query with all words, all words near to each others, any words, or boolean queries. A subset of VQL (Verity Query Language) is supported.

FSearch is a fast file search utility, inspired by Everything Search Engine. It is written in C and based on GTK3.

Recoll finds documents based on their contents as well as their file names. It can search most document formats, but you may need external applications for text extraction. It can reach any storage place: files, archive members, email attachments, transparently handling decompression.

Xapian is a highly adaptable toolkit which allows developers to easily add advanced indexing and search facilities to their own applications. It supports the Probabilistic Information Retrieval model and also supports a rich set of boolean query operators.

libtocc is the engine of the Tocc project, a tag-based file management system. The goal of Tocc is to provide a better system for classifying files that is more flexible than classic file systems that are based on a tree of files and directories.

Xapers is a personal document indexing system, geared towards academic journal articles build on the Xapian search engine. Think of it as your own personal document search engine, or a local cache of online libraries. It provides fast search of document text and bibliographic data and simple document and bibtex retrieval.

Swish-e is Simple Web Indexing System for Humans - Enhanced. Swish-e can quickly and easily index directories of files or remote web sites and search the generated indexes.

Search::Xapian wraps most methods of most Xapian classes. The missing classes and methods should be added in the future. It also provides a simplified, more 'perlish' interface to some common operations.
