Geiser features an enhanced REPL and a set of minor modes improving Emacs' basic scheme major mode. The main functionalities provided are:
- 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.
- Access to documentation (including docstrings when the
implementation provides it).
- Listings of identifiers exported by a given module.
- Listings of callers/callees of procedures.
- Rudimentary support for debugging (list of
evaluation/compilation error in an Emacs' compilation-mode
buffer).
