delta vs RetroArch

delta is a free, open-source pager for Git and related command-line output, including diffs, grep, ripgrep JSON, and blame. It can show diffs side by side with line numbers and automatic wrapping, and highlight edits within lines using a Levenshtein edit inference algorithm. Its syntax themes are the ones available with bat. Delta can be configured as Git’s pager and interactive diff filter, and its documentation covers zdiff3 for merge conflicts. It can highlight output from ripgrep, git grep, and grep; blame and diff hyperlinks can target GitHub, GitLab, SourceHut, and Codeberg. The manual also describes integrations with Magit, VS Code, tmux, and GNU Screen. Executables are offered for Linux glibc, Linux musl, macOS, and Windows, alongside package-manager installation instructions. Paging depends on less, for which the project recommends a reasonably recent version. The project includes the MIT License. The listed git-delta plan costs nothing.

RetroArch is a frontend for emulators, game engines, and media players, bringing them under a unified settings system. The RetroArch/Libretro project includes more than 200 cores across those categories. Its menu can group scanned games by system and display thumbnails and animated backgrounds. Common game controllers configure automatically when plugged in, and button actions can also be assigned manually.

Stackable shaders can change rendered graphics or imitate the look of CRT monitors. Built-in netplay supports hosting or joining network gaming sessions, including spectator mode. RetroArch can record gameplay to video files and stream games to Twitch or YouTube. Versions are listed for Windows, Linux, Android, iOS, macOS, and web browsers. RetroArch is free and open source under GPL version 3; the libretro API uses an MIT license. Features differ by platform and store version: the browser edition has lower performance and fewer capabilities than the full version, while Steam lacks Core Updater and thumbnail scraping and offers a selected core set.
