Font-lock, indentation, navigation, documentation, and repl support for the Fennel programming language.

Supports M-x imenu for quick navigation to local definitions.

Place fennel-mode.el on your load-path and add this to your config:

(autoload 'fennel-mode "/path/to/fennel-mode/fennel-mode" nil t)
(add-to-list 'auto-mode-alist '("\\.fnl\\'" . fennel-mode))

Run C-u M-x run-lisp RET fennel RET to open a repl buffer. Once a repl is open, you can send code from a fennel-mode buffer to be evaluated.

• C-c C-z - Start or switch to repl buffer
• C-c C-e - Evaluate current top-level form
• C-c C-r - Evaluate the region
• C-c C-k - Reload the module for the current file (requires fennel.seacher)
• C-c C-d - Ask for a value and show its docstring in the repl
• C-c C-l - Display compilation output for the current file
• M-. - Jump to the definition of the function at point
• M-, - Jump back to where you were before jumping to definition

These functions assume a fennel executable is present on your path. You can override the location by setting inferior-lisp-program. For instance, if you have a stdio repl in a LÖVE game, you can set this to love . to get an interactive support with reloads.
