CudaText
What it is
CudaText is a free, cross-platform text editor written in Object Pascal, with builds for Windows, Linux, and macOS. It provides syntax highlighting for more than 300 languages, along with code folding, multiple carets and selections, regular-expression search and replacement, and customizable hotkeys. A code tree can display functions and classes when the relevant lexer supports it, while a fuzzy-matching command palette helps locate commands. For large files, its binary and hex viewer supports files of unlimited size; the site says it can display 10 GB logs. HTML and CSS tools include smart auto-completion, tag completion through the Snippets plugin, and in-editor image display. Python add-ons can supply plugins, linters, code tree parsers, and external tools. Listed plugin capabilities include LSP support, project and session managers, an FTP panel, spell checking, and formatters. Settings use JSON files and can be tailored to individual lexers. The project identifies its license as MPL-2.0. Linux Qt5 and Qt6 builds require libqt5pas or libqt6pas; Python is not included in Linux and Unix builds and must be installed separately on macOS to use plugins. The plan is free.
