Instead of building this project yourself, you can download the binary from bintray


Fetch the source of JTcl using mercurial and replace the maven-jar-plugin config with the following in order to generate the test jar

            <manifestEntries />

If you're using Mac Os X and don't have mercurial installed, I recommend using the Source Tree app from the app store. It has excellent support for both git and mercurial. The next step, is to build and install the artifacts into your local maven repository using

mvn clean install -DskipTests

WARNING! you have to use JDK version 1.6. You can achieve this by setting JAVA_HOME appropriately.

Next, fetch the source code of this project, and align the jtcl.version property in pom.xmlin with the JTcl version. Then, build the project using:

mvn clean package

This will generate a jar file named jtcl-irule.jar in the target directory. This jar file has to be added to the classpath of the JTcl shell script in order to override som of the functionality found in JTcl. Place it in front of the other jar file - it will take precedence. See TesTcl installation instructions for details.

What has been implemented so far

All the special iRule operators have now been implemented!

Original JTcl source code was modified in order to support the following iRule operators:

iRule only operators

iRule aliases to standard Tcl operators

The only files that have been modified are:


Both jtcl-irule and JTcl are released under a BSD-style license.
