Geiser is a generic Emacs/Scheme interaction mode, featuring an enhanced REPL and a set of minor modes improving Emacs' basic scheme major mode.

Geiser supports Racket and Guile.

Main functionalities:

- Evaluation of forms in the namespace of the current module.

- Macro expansion.

- File/module loading.

- Namespace-aware identifier completion (including local bindings, names visible in the current module, and module names).

- Autodoc: the echo area shows information about the signature of the procedure/macro around point automatically.

- Jump to definition of identifier at point.

- Direct access to documentation, including docstrings (when the implementation provides them) and user manuals.

- Listings of identifiers exported by a given module (Guile).

- Listings of callers/callees of procedures (Guile).

- Rudimentary support for debugging (list of evaluation/compilation error in an Emacs' compilation-mode buffer).

- Support for inline images in schemes, such as Racket, that treat them as first order values.
