GITANT
======

Exports information on your Git repository into Ant properties.

Basic Usage:
============
See build.xml for an up to date example.

        <git-info 
           baseDir=".git" 
           propertyPrefix=""
           displayInfo="true"
           />

Ant Task Options:
=================
baseDir: Where the Git repository is located. Relative to your project
base dir.

propertyPrefix: GitAnt exports Properties into your Ant Buildfile. If
you want to run this on multiple Checkouts, you can specify a prefix
for the properties which will be used (this means for a prefix like
"main." the property "git.tag" becomes "main.git.tag".

displayInfo: Output information about the state during build:

 [git-info] Currently on branch master which is clean
 [git-info] Last Commit: d3169e69c054827b987055d7565736c3ff50e97d
 [git-info] Last Tag: v0.0.5 which is dirty

Dirty Tag means that there were changes to the repository since the
tag. Branch dirty means that you have local uncommitted changes.

Exported Properties:
===================
GitAnt exports the following Properties, which can be prefixes through
the propertyPrefix option with a custom prefix:

git.branch: The name of the branch you are currently on.

git.workingcopy.dirty: Is the workingcopy dirty or clean (i.e. are
there uncommitted changes). Boolean, "true" or "false".

git.commit: The SHA of the last commit on this repo.

git.tag: The name of the tag that is closest to HEAD seen through a
breadth first search.

git.tag.dirty: Is the tag dirty, i.e. have there been other commits
since the tag.

git.dirty: Deprecated, will be removed in later versions

Extended Usage:
===============
What do I do with it? Create a Version file for your application
during build:

    <target name="Version.java" depends="prepare">
        <tstamp>
            <format property="COMPTIME" pattern="dd.MM.yyyy HH:mm"/>
        </tstamp>
        <delete file="${Version.java.target}"/>
        <filter token="BRANCH" value="${git.branch}"/>
        <filter token="TAG" value="${git.tag}"/>
        <filter token="COMMIT" value="${git.commit}"/>
        <filter token="TAG_DIRTY" value="${git.tag.dirty}"/>
        <filter token="TAG_WORKINGCOPY_DIRTY" value="${git.workingcopy.dirty}"/>
        <filter token="COMPILE_TIME" value="${COMPTIME}"/>
        <copy file="${etc}/Version.java.tmpl" tofile="${Version.java.target}" filtering="yes"/>
    </target>
