<h3 class="section">5.8 Handling of case exceptions</h3>
<p><a name="index-casing-210"></a><!-- -->
<p>GPS keeps a set of case exceptions that is used by all
case insensitive languages. When editing or reformatting a buffer for
such a language the case exception dictionary will be checked
first. If an exception is found for this word or a substring of the
word, it will be used; otherwise the specified casing for keywords or
identifiers is used. A substring is defined as a part of the word
separated by underscores.
<p>Note that this feature is not activated for entities (keywords or
identifiers) for which the casing is set to <code>Unchanged</code>. See
see <a href="The-Preferences-Dialog.html#The-Preferences-Dialog">The Preferences Dialog</a>.
<p>A contextual menu named <b>Casing</b> has the following entries:
<dl>
<dt><b>Lower </b><i>entity</i><dd>Set the selected entity in lower case.
<br><dt><b>Upper </b><i>entity</i><dd>Set the selected entity in upper case.
<br><dt><b>Mixed </b><i>entity</i><dd>Set the selected entity in mixed case (set the first letter and
letters before an underscore in upper case, all other letters are set
to lower case).
<br><dt><b>Smart Mixed </b><i>entity</i><dd>Set the selected entity in smart mixed case. Idem as above except that
upper case letters are kept unchanged.
<br><dt><b>Add exception for </b><i>entity</i><dd>Add the current entity into the case exception dictionary.
<br><dt><b>Remove exception for </b><i>entity</i><dd>Remove the current entity from the case exception dictionary.
</dl>
<p>To add or remove a substring exception into/from the dictionary you need to
first select the substring on the editor. In this case the last two
contextual menu entries will be:
<dl>
<dt><b>Add substring exception for </b><i>str</i><dd>Add the selected substring into the case substring exception dictionary.
<br><dt><b>Remove substring exception for </b><i>str</i><dd>Remove the selected substring from the case substring exception dictionary.
</dl>
