<hr>
<p>
Commands you can type to the <em>hmake interactive</em> prompt are
very like those for Hugs. There are just a few extra and a few
missing. Any command can be abbreviated to its shortest unique prefix.
<p>
<b>Commands that are identical in <em>hi</em> and Hugs:</b>
<table><tr>
<td><tt>expr</tt></td>
<td>evaluate the expression</td>
</tr><tr>
<td><tt>:?</tt></td>
<td>display help text</td>
</tr><tr>
<td><tt>:quit</tt></td>
<td>exit</td>
</tr><tr>
<td><tt>:load mod [mod...]</tt></td>
<td>load the named modules (note, not filenames!)</td>
</tr><tr>
<td><tt>:load</tt></td>
<td>remove all modules</td>
</tr><tr>
<td><tt>:reload</tt></td>
<td>repeat the last :load command</td>
</tr><tr>
<td><tt>:also mod [mod...]</tt></td>
<td>load additional modules</td>
</tr><tr>
<td><tt>:edit file</tt></td>
<td>edit filename</td>
</tr><tr>
<td><tt>:edit</tt></td>
<td>edit the current module</td>
</tr><tr>
<td><tt>:cd dir</tt></td>
<td>change the current directory</td>
</tr><tr>
<td><tt>:cd</tt></td>
<td>show the current directory</td>
</tr><tr>
<td><tt>:dir</tt></td>
<td>list the current directory</td>
</tr><tr>
<td><tt>:set options</tt></td>
<td>set hmake/compiler options</td>
</tr><tr>
<td><tt>:set</tt></td>

<td>unset hmake/compiler options</td>
</tr><tr>
<td><tt>:!command</tt></td>
<td>shell escape</td>
</tr><tr>

</tr></table>
<p>
<b>Commands that are supported by <em>hi</em> (but not by Hugs):</b>
<table><tr>
<td><tt>:hc compiler</tt></td>
<td>change Haskell compiler</td>
</tr><tr>
<td valign=top><tt>:hc</tt></td>
<td valign=top>report current Haskell compiler,
and show available compilers</td>
</tr></table>
<p>
<b>Hugs commands which are not supported in <em>hi</em>:</b>
<table><tr>
<td><tt>:names pat</tt></td>
<td>list names currently in scope</td>
</tr><tr>
<td><tt>:info name</tt></td>
<td>describe the named object</td>
</tr><tr>
<td valign=top><tt>:find name</tt></td>
<td valign=top>edit the module containing the definition of name<br>
(suggestion: use
<tt>:!grep ^name *.hs</tt> to find the module)</td>
</tr><tr>
<td valign=top><tt>:project filename</tt></td>
<td valign=top>obsolete (project files were an alternative to the<br>
Haskell module system)</td>
</tr><tr>
<td valign=top><tt>:gc</tt></td>
<td valign=top>force a garbage collection<br>
(only makes sense in a true interpreter)</td>
