Description

This package adds support for the Gauche Scheme implementation to Geiser, a generic Scheme interaction mode for the GNU Emacs editor.

Currently the following Geiser features are supported:

• evaluation of sexps, definitions, regions and whole buffers,
• loading Scheme files,
• macroexpansion,
• identifier completion,
• short symbol and module documentation,
• detailed symbol and module documentation lookup in the Gauche Info manual.

Requirements

• Gauche 0.9.6 or later.
• Geiser 0.11.2 or later.

Installation and setup

1. Install the package, which is available in the MELPA package repository and can be installed using Emacs’s built-in package manager, package.el.
2. Add Gauche to Geiser's list of active Scheme implementations in your Emacs init file. This can be done, e.g., by adding

(with-eval-after-load 'geiser-impl
  (add-to-list 'geiser-active-implementations 'gauche))

or, using use-package

(use-package geiser-gauche
  :after geiser
  :init (add-to-list 'geiser-active-implementations 'gauche))

Naturally, if the geiser-active-implementations variable is already customized in the init file then one can simply add 'gauche to the set value, e.g. replace

(setq geiser-active-implementations '(guile chez))

with

(setq geiser-active-implementations '(guile chez gauche))

3. If Gauche's gosh binary is not in the path for Emacs then the variable geiser-gauche-binary also has to be set in the init file, e.g., with

(setq geiser-gauche-binary /path/to/gosh)
