M-x package-install chicken-scheme
A suite of extensions for scheme-mode that grew out of necessity.
Chicken Scheme does play well with SLIME (See also: chicken-slime.el), but
I often find myself working on software that is slow-level and unstable
enough to make such dependence on REPL reliability rather frustrating.
Thus chicken-scheme.el was born. It does not rely on a running Scheme to
provide auto-complete support for your application. A suite of customization
variables are available to configure from which modules symbols should be
loaded and what sort of package prefixes can be expected.
Auto-complete is configured to support prefixed symbols, to allow for
full recognition of symbols in modules that may have been imported with a
prefix modifier. The `chicken-prefix` variable may be customized to declare
what characters can be used as prefix delimiters.
C-? is bound in Scheme Modes to fetch documentation for the symbol at the
current point. This obeys the prefix rules used for auto-complete.
Further customization is available in the chicken-scheme customization group.
Loading of the first scheme file may take some time as the Chicken Modules
are parsed for symbols on first-load. All subsequent scheme files do not
incur this load hitch. Consider running an Emacs daemon.
Tags are also supported.
Place in your load path. Add the following to your .emacs:
Two Auto-Complete sources are available:
Prefixed symbols are those which have been mutated after importing a library.
See the chicken-prefix custom variable for customization options.
I recommend you also add the following:
(add-hook 'scheme-mode-hook 'enable-paredit-mode)
(add-hook 'scheme-mode-hook 'rainbow-delimiters-mode-enable)
