    text
    copied!<p>I have a flash project which, for optimization purposes, has to have constant references replaced with literals during release build.</p> <p>There are hundreds of constants which I want to replace. All of them are stored in single file, in this format:</p> <pre><code>FILE: Constants.as public static const CONST_1 :uint = 0; public static const CONST_LOLO :int = -1; public static const CONST_WHEE :Number = 2.55; public static const OTHER_CONST :String = "La string!"; public static const ITSAMEMARIO :String = "O, HAI!"; public static const MAGE_WALL :uint = 15; </code></pre> <p>I figure I could do it manually, like that:</p> <pre><code>&lt;replaceregexp match="CONST_1" replace="0"&gt; &lt;fileset dir="${project.sourcePath}" includes="**/*.as" /&gt; &lt;/replaceregexp&gt; &lt;replaceregexp match="CONST_LOLO" replace="-1"&gt; &lt;fileset dir="${project.sourcePath}" includes="**/*.as" /&gt; &lt;/replaceregexp&gt; </code></pre> <p>And so on, for all the other variables. The problem is twofold - first of all, it is quite a lot of work. But the bigger problem is, that these constants can change and I'd have to remember to do the change in two places.</p> <p>Generally I am using Ant (which I just started to learn too) to accomplish this task, but if you think there is a better way, I am all ears. There are two solutions I can think of, none of which I know how to execute:</p> <ol> <li>Write some smarty-pants piece of Ant code which would parse this constants file and happily do the replaces keeping everything in memory.</li> <li>Make the task first parse the <em>Constants.as</em>, output a new Ant script, which then will be executed by the first task.</li> </ol> <p>I am using Flash Builder 4.5 for all my Ant needs.</p> <p>EDIT: Some clarification. In the project I am using Constants, for example LEVEL_WIDTH. All of these constants are declared in the aforementioned Constants.as. Now what I want is to replace all of the instances of these constants in the whole project with their actual value. So such line:</p> <pre><code>return (x &gt;= 0 &amp;&amp; x &lt; Constants.LEVEL_WIDTH); </code></pre> <p>will be replaced by:</p> <pre><code>return (x &gt;= 0 &amp;&amp; x &lt; 20); </code></pre>
