MIT/GNU Scheme

<h2 id="edwin">Edwin</h2>
<p>Edwin is a built-in Emacs-like editor that comes with MIT/GNU Scheme. Edwin normally displays the *scheme* <a href="/facts/Data_buffer/tVy4j2Dc">data buffer</a>, the mode line, and the mini-buffer when it starts. As in Emacs, the mode line gives information like the name of the buffer above it and whether that buffer is read-only, modified, or unmodified.

<p>When the user exits the interpreter, an exit message is printed. Possible messages include the following.<a class="footnote-ref" id="fnref:6" href="#fn:6"><sup>6</sup></a>

Quote from developer on Savannah (Gnu's forum site):</p><blockquote><p>"<i>Originally, there was just one Latin message: moriturus te saluto: "I who am about to die salute you."  It was added by Guillermo Rozas in reference to the phrase morituri te saltamus, "we who are about to die salute you," shouted to the Roman emperor by gladiators before they began to fight in an arena (<a href="/facts/Ave_Imperator%2c_morituri_te_salutant/gSY5GVLA">Wikipedia</a>).  The idea is that the Scheme process, singular, salutes the user before dying.  Much later, there was debate over the correctness of the conversion from third person to first person: <a href="https://savannah.gnu.org/bugs/?44086">bug report</a>.  We changed the verb ending, but I'm still not sure whether that was necessary.</i>"<a class="footnote-ref" id="fnref:7" href="#fn:7"><sup>7</sup></a>
