‘inform-mode’ is an Emacs major mode for editing source code in the Inform 6 programming language.

‘inform-mode’ supports the usual Emacs program mode functions: automatic indentation, moving over expressions, comment and string filling, font locking, tags-file support, starting compiles and parsing errors. You can also run a Z-code interpreter against the compiled code.

Inform 6 is an object-oriented language for writing interactive fiction, also known as “text adventures” or “adventure games”.
