|

|
|
provides thorough syntax highlighting and DrRacket-style REPL
|
||
|
|
and buffer execution support for Emacs.</p><p>Racket mode can be installed via <a href="https://melpa.org/">MELPA</a>
|
||
|
|
or manually from the Github repository.</p></li><li><p><a href="http://www.neilvandyke.org/quack/">Quack</a> is an
|
||
|
|
extension of Emacs’s <span class="stt">scheme-mode</span> that provides enhanced
|
||
|
|
support for Racket, including highlighting and indentation of
|
||
|
|
Racket-specific forms, and documentation integration.</p><p>Quack is included in the Debian and Ubuntu repositories as part
|
||
|
|
of the <span class="stt">emacs-goodies-el</span> package. A Gentoo port is also
|
||
|
|
available (under the name <span class="stt">app-emacs/quack</span>).</p></li><li><p><a href="https://www.nongnu.org/geiser/">Geiser</a> provides a
|
||
|
|
programming environment where the editor is tightly integrated
|
||
|
|
with the Racket REPL. Programmers accustomed to environments
|
||
|
|
such as Slime or Squeak should feel at home using
|
||
|
|
Geiser. Geiser requires GNU Emacs 23.2 or better.</p><p>Quack and Geiser can be used together, and complement each
|
||
|
|
other nicely. More information is available in the
|
||
|
|
<a href="https://www.nongnu.org/geiser/">Geiser manual</a>.</p><p>Debian and Ubuntu packages for Geiser are available under the
|
||
|
|
name <span class="stt">geiser</span>.</p></li><li><p>Emacs ships with a major mode for Scheme, <span class="stt">scheme-mode</span>,
|
||
|
|
that while not as featureful as the above options, works
|
||
|
|
reasonably well for editing Racket code. However, this mode
|
||
|
|
does not provide support for Racket-specific forms.</p></li><li><p>No Racket program is complete without documentation. Scribble
|
||
|
|
support for Emacs is available with Neil Van Dyke’s
|
||
|
|
<a href="http://www.neilvandyke.org/scribble-emacs/">Scribble
|
||
|
|
Mode</a>.</p><p>In addition, <span class="stt">texinfo-mode</span> (included with GNU Emacs) and
|
||
|
|
plain text modes work well when editing Scribble
|
||
|
|
documents. The Racket major modes above are not really suited
|
||
|
|
to this task, given how different Scribble’s syntax is from
|
||
|
|
Racket’s.</p></li></ul><h5 x-source-module="(lib "scribblings/guide/guide.scrbl")" x-source-pkg="racket-doc" x-part-tag=""Minor_Modes"">24.2.2<tt> </tt><a name="(part._.Minor_.Modes)"></a>Minor Modes</h5><ul><li><p><a href="http://mumble.net/~campbell/emacs/paredit.el">Paredit</a>
|
||
|
|
is a minor mode for pseudo-structurally editing programs in
|
||
|
|
Lisp-like languages. In addition to providing high-level
|
||
|
|
S-expression editing commands, it prevents you from
|
||
|
|
accidentally unbalancing parentheses.</p><p>Debian and Ubuntu packages for Paredit are available under the
|
||
|
|
name <span class="stt">paredit-el</span>.</p></li><li><p><a href="https://github.com/Fuco1/smartparens">Smartparens</a>
|
||
|
|
is a minor mode for editing s-expressions, keeping parentheses
|
||
|
|
balanced, etc. Similar to Paredit.</p></li><li><p>Alex Shinn’s
|
||
|
|
<a href="http://synthcode.com/wiki/scheme-complete">scheme-complete</a>
|
||
|
|
provides intelligent, context-sensitive code completion. It
|
||
|
|
also integrates with Emacs’s <span class="stt">eldoc</span> mode to provide live
|
||
|
|
documentation in the minibuffer.</p><p>While this mode was designed for <a href="standards.html#%28part._r5rs%29" data-pltdoc="x">R<span style="vertical-align: super; font-size: 80%">5</span>RS</a>, it
|
||
|
|
can still be useful for Racket development. The tool is
|
||
|
|
unaware of large portions of the Racket standard library, and
|
||
|
|
there may be some discrepancies in the live documentation in
|
||
|
|
cases where Scheme and Racket have diverged.</p></li><li><p>The
|
||
|
|
<a href="https://www.emacswiki.org/emacs/RainbowDelimiters">RainbowDelimiters</a>
|
||
|
|
mode colors parentheses and other delimiters according to their
|
||
|
|
nesting depth. Coloring by nesting depth makes it easier to
|
||
|
|
know, at a glance, which parentheses match.</p></li><li><p><a href="https://www.emacswiki.org/emacs/ParenFace">ParenFace</a>
|
||
|
|
lets you choose in which face (font, color, etc.) parentheses
|
||
|
|
should be displayed. Choosing an alternate face makes it
|
||
|
|
possible to make “tone down” parentheses.</p></li></ul><h5 x-source-module="(lib "scribblings/guide/guide.scrbl")" x-source-pkg="racket-doc" x-part-tag=""Packages_specific_to_Evil_Mode"">24.2.3<tt> </tt><a name="(part._.Packages_specific_to_.Evil_.Mode)"></a>Packages specific to Evil Mode</h5><ul><li><p><a href="https://github.com/willghatch/emacs-on-parens">on-parens</a>
