Using booleans as string values leads to strange results

[burobjorn@…]

I'm using a ReplaceRegexp filter to change WordPress' wp-config.php file. In this file a constant WP_DEBUG is defined false and I would to change it to true. I have defined the regex and provided a property with a string "true". However this string will be casted to a bool and causes strange sideeffects.

Consider this build.xml example:

<property name="wp_config.wp_debug" value="true" />

<target name="setup-wp-config" description="Copies the wp-config-sample.php to wp-config.php and sets up the parameters for the audition test site">

<copy file="./wp-config-sample.php" tofile="./wp-config.php">

<filterchain>

<replaceregexp>

<regexp pattern="(define\('WP_DEBUG', )\w+(\);)" replace="\1${wp_config.wp_debug}\2"/>

</replaceregexp>

</filterchain>

</copy>

</target>

If you would run this it would not work as expected. Changing the property to "foo" it does work as expected. This is probably related to this thread:

Using the workaround in the thread the example becomes:

<property name="wp_config.wp_debug" value="(bool)true" />

<target name="setup-wp-config" description="Copies the wp-config-sample.php to wp-config.php and sets up the parameters for the audition test site">

<copy file="./wp-config-sample.php" tofile="./wp-config.php">

<filterchain>

<replaceregexp>

<regexp pattern="(define\('WP_DEBUG', )\w+(\);)" replace="\1${wp_config.wp_debug}\2"/>

</replaceregexp>

</filterchain>

</copy>

</target>

Thus by adding the type (bool) forces Phing to work correctly with boolean values as strings. Thanks Hans Lellelid for this workaround!
