64 Deep indentation means that lines will be indented relative to the current
65 parentheses or assignment offset. This way consecutive code sections are somewhat easier
66 to recognize at the downside of consuming more horizontal space.

219 Normally, Jalopy uses spaces to indent lines. If you prefer tabs, check this box.
221 Indent "case" from "switch"
223 The Sun Java code convention recommends a switch style where case statements
224 are not indented relative to the switch statement as a whole. However, this
225 option allows you to indent the case statements to make the entire switch
227 </p><div class="example"><a name="ex-indentation-misch-switch-un"></a><p class="title"><b>Example 4.45. Switch statement (unindented)</b></p><table border="0" bgcolor="#E0E0E0" class="shade"><tr><td><pre class="programlisting">

299 Indent first column comments
301 Normally, all comments will be indented relative to their position in the code
302 to avoid that comments break the logical structure of the program. Some
303 developers may like to disable the indentation for first column comments
304 during the developing phase.

359 Method Def parameters
361 If enabled, aligns the parameters of method declarations. This only applies if
362 all parameters will be wrapped; either because wrapping is forced or the
363 max. line length is reached. To force aligning, you have to enable the
364 wrapping for method parameters (See <a href="wrapping.html#wrap-method-params">Method Def parameters</a>).
365 </p><a class="indexterm" name="d0e2524"></a><a class="indexterm" name="d0e2527"></a><div class="example"><a name="ex-indentation-align-params"></a><p class="title"><b>Example 4.55.

418 The Sun brace style could make seeing the statement body difficult. To
419 workaround this problem, you may want to use continuation indentation in case you like this
420 brace style. This setting applies for <tt class="literal">if</tt>, <tt class="literal">for</tt>, <tt class="literal">while</tt>
421 and <tt class="literal">do-while</tt> blocks.
