What is an FNL file?
An FNL file is a source code file written in Fennel, a programming language that combines Lisp-style syntax with the Lua runtime environment. It contains program instructions written in a text-based format. Developers often compile Fennel source code into .LUA code, allowing it to run anywhere Lua is supported.
More Information
FNL files are typically used by developers who want to write Lua applications with a Lisp-inspired syntax. They commonly use FNL files for scripting, application development, game development, automation, configuration systems, and editor customization workflows such as those built around Lua-based environments.
Since Fennel compiles to Lua, FNL files can be used in environments that support Lua without requiring a dedicated Fennel runtime. This compatibility has made the format useful in scripting, game development, editor customization, and automation workflows.
How to open an FNL file
You can open FNL files with any text editor or source code editor, such as Microsoft Visual Studio Code or GNU Emacs. To run or compile the file, use the Fennel compiler. Many development environments provide syntax highlighting and build tools that help compile FNL files into executable Lua code.
