Pattern: Line is too long

Issue: -

Description

Your source code should not contain very long lines. The default wrapping in most tools disrupts the visual structure of the code, making it more difficult to understand.

Configuration

This rule checks all lines in a file and generates warnings if they are over lineLimit characters in length and errors if they are over absoluteLineLimit in length. These properties can be used to set the threshold at which errors are reported.

Note: The value of the lineLimit property should be less than or equal to the value of the absoluteLineLimit property.

<!--
 Warn about lines longer than 100 chars,
 and error for lines longer than 135 chars.
-->
<rule ref="Generic.Files.LineLength">
    <properties>
        <property name="lineLimit" value="100" />
        <property name="absoluteLineLimit" value="135" />
    </properties>
</rule>

If errors are not required, the value of absoluteLineLimit can be set to zero.

<!-- Warn about lines longer than 135 chars, and never error. -->
<rule ref="Generic.Files.LineLength">
    <properties>
        <property name="lineLimit" value="135" />
        <property name="absoluteLineLimit" value="0" />
    </properties>
</rule>

If the ignoreComments property is set to true, no error or warning will be thrown for a line that only contains a comment, no matter how long the line is.

<rule ref="Generic.Files.LineLength">
    <properties>
        <property name="ignoreComments" value="true" />
    </properties>
</rule>
