Bluefish is a lightweight yet powerful text editor written for programmers and web developers. It seeks to fill the niche between simple text editors (Notepad, Text Edit) and full-fledged integrated development environments (Eclipse, IntelliJ). Because of its small resource footprint, Bluefish can simultaneously work across many dozens of files even on very modest hardware like netbooks. It has integrated support for editing remote files using a number of protocols (FTP, SFTP, WebDav, and others). Bluefish includes syntax highlighting and in-line language reference information for HTML, CSS, Javascript, and many common (and not so common) programming languages. Additionally, Bluefish allows users to define 'snippets' -- frequently repeated stanzas of text -- and connect them to keyboard shortcuts. Bluefish is available for Windows, macOS, and Linux.
