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
- Support for inline images in schemes, such as Racket, that treat
them as first order values.
Chicken Addendum:
These steps are necessary to fully support Chicken Scheme, but are
not required for any other scheme.
- Install the necessary support eggs:
$ chicken-install -s apropos chicken-doc
- Update the Chicken documentation database:
$ cd `csi -p '(chicken-home)'`
$ curl | sudo tar zx
