Lite XL is a lightweight text editor designed around a small core and an extensive plugin system. It provides a fast graphical editing environment while making it straightforward to add commands, language support and interface functionality using Lua.
The editor works with projects as well as individual files. Directories can be added to a workspace, files can be located through fuzzy matching, and commands are available through a searchable palette.
Lite XL’s extensibility is central to its design. Users can install plugins and themes or write their own, allowing the base application to remain comparatively compact while still accommodating more sophisticated programming workflows.
This is free and open source software.
