|
||
|
|
<p>Any text editor can edit Scheme, but some are better than others. Emacs
|
||
|
|
is the best, of course, and not just because it is a fine text editor.
|
||
|
|
Emacs has good support for Scheme out of the box, with sensible
|
||
|
|
indentation rules, parenthesis-matching, syntax highlighting, and even a
|
||
|
|
set of keybindings for structural editing, allowing navigation,
|
||
|
|
cut-and-paste, and transposition operations that work on balanced
|
||
|
|
S-expressions.
|
||
|
|
</p>
|
||
|
|
<p>As good as it is, though, two things will vastly improve your experience
|
||
|
|
with Emacs and Guile.
|
||
|
|
</p>
|
||
|
|
<a class="index-entry-id" id="index-Paredit"></a>
|
||
|
|
<p>The first is Taylor Campbell’s
|
||
|
|
<a class="uref" href="http://www.emacswiki.org/emacs/ParEdit">Paredit</a>. You should not
|
||
|
|
code in any dialect of Lisp without Paredit. (They say that
|
||
|
|
unopinionated writing is boring—hence this tone—but it’s the
|
||
|
|
truth, regardless.) Paredit is the bee’s knees.
|
||
|
|
</p>
|
||
|
|
<a class="index-entry-id" id="index-Geiser"></a>
|
||
|
|
<p>The second is
|
||
|
|
José
|
||
|
|
Antonio Ortega Ruiz’s
|
||
|
|
<a class="uref" href="http://www.nongnu.org/geiser/">Geiser</a>. Geiser complements Emacs’
|
||
|
|
<code class="code">scheme-mode</code> with tight integration to running Guile processes via
|
||
|
|
a <code class="code">comint-mode</code> REPL buffer.
|
||
|
|
</p>
|
||
|
|
<p>Of course there are keybindings to switch to the REPL, and a good REPL
|
||
|
|
environment, but Geiser goes beyond that, providing:
|
||
|
|
</p>
|
||
|
|
<ul class="itemize mark-bullet">
|
||
|
|
<li>Form evaluation in the context of the current file’s module.
|
||
|
|
</li><li>Macro expansion.
|
||
|
|
</li><li>File/module loading and/or compilation.
|
||
|
|
</li><li>Namespace-aware identifier completion (including local bindings, names
|
||
|
|
visible in the current module, and module names).
|
||
|
|
</li><li>Autodoc: the echo area shows information about the signature of the
|
||
|
|
procedure/macro around point automatically.
|
||
|
|
</li><li>Jump to definition of identifier at point.
|
||
|
|
</li><li>Access to documentation (including docstrings when the implementation
|
||
|
|
provides it).
|
||
|
|
</li><li>Listings of identifiers exported by a given module.
|
||
|
|
</li><li>Listings of callers/callees of procedures.
|
||
|
|
</li><li>Rudimentary support for debugging and error navigation.
|
||
|
|
</li><li>Support for multiple, simultaneous REPLs.
|
||
|
|
</li></ul>
