Update your app VERSION using ant

This is just a quick tip in case someone needs it. Maybe when you compile your flash application or your swc library you want to automatically update the “ VERSION” number too without do it manually every time.

This is the way I do. In the “compile” task I’ve added a depends link to this ant task:

<target name="update-version"> <propertyset id="tdate"></propertyset> <tstamp> <format property="tdate" pattern="yyyyMMdd"/> </tstamp> <buildnumber file="build.number"/> <echo>updating version to current datetime: ${tdate}</echo> <replaceregexp byline="true"> <regexp pattern="public static const BUILD_DATE: String = \'([0-9]+)'"/> <substitution expression="public static const BUILD_DATE: String = '${tdate}'"/> <fileset dir="src/it/sephiroth/somestuff"> <include name="Library.as"/> </fileset> </replaceregexp> <replaceregexp byline="true"> <regexp pattern="public static const BUILD_NUMBER: String = \'([0-9\.]+)'"/> <substitution expression="public static const BUILD_NUMBER: String = '${build.number}'"/> <fileset dir="src/it/sephiroth/somestuff"> <include name="Library.as"/> </fileset> </replaceregexp> </target>

The 2 optional tasks I’ve used are: BuildNumber task and ReplaceRegExp Task. In this way every time I do an ant compile, it will update my build number and modification date.
What this task does is find this 2 lines in my Library.as file:

public static const BUILD_DATE: String = ‘20100131’;

public static const BUILD_NUMBER: String = ‘5’;

then replace the BUILD_DATE const with the current date and the BUILD_NUMBER with an incremental build number. After being executed the first time, ant will also create a new file in your directory called “build.number” with the latest build number int.

    Nice, I was just thinking about it this weekend and wanted to make something like this, saves me some time to do something else! 🙂 http://www.giezentweewielers.nl/?how-to-prepare-phd-proposal How To Prepare Phd Proposal I would also like the SVN revision number in, but I might use your ‘template’ to create a thing like that. (Or do you happen to have something for it already?)
