Using Libraries

Lite XL implements most of the functionalities in Lua, but it would be impossible to create a window, get input events, or perform various filesystem operations in pure Lua, without relying on functions provided by the platform.

Lite XL has its own bindings to SDL2, which provides cross-platform abstractions to windowing and event handling. Other than that Lite XL also uses PCRE2 to provide support for regular expressions as Lua only has a simple pattern-based matching engine. Finally, Lite XL provides an API for running starting and managing programs, as well as handling the input / output of the program without blocking the editor.
