Demonstration of using intrinsic redundancy to support the integration and preservation of hand-written content within generated files. The approach requires that generated files are only extended with new lines of content (i.e. existing lines are neither modified nor deleted). The prototype has been implemented on top of the EGL model-to-text transformation language.

• Clone this repository
• Download and install Java 17
• Download and install Maven
• Run mvn compile exec:java from the command line
• Open the generated gen/Alice.html file
• Add a hand-written <p>Alice is an experienced systems analyst.</p> line to it as follows

<h1>Alice's Tasks</h1>
<p>Alice is an experienced systems analyst.</p>

<ul>
  <li>Analysis</li>
  <li>Design</li>
</ul>

• Edit acme.flexmi to assign Alice to the Implementation task as follows

<?nsuri psl?>
<project title="ACME">
	<person name="Alice"/>
	<person name="Bob"/>
	<task title="Analysis" start="1" dur="3">
		<effort person="Alice"/>
	</task>
	<task title="Design" start="4" dur="6">
		<effort person="Alice"/>
		<effort person="Bob"/>
	</task>
	<task title="Implementation" start="7" dur="3">
		<effort person="Bob" perc="50"/>
		<effort person="Alice" perc="50"/>
	</task>
</project>

• Re-run the generator using mvn compile exec:java
• Observe how gen/Alice.html now contains a new Implementation row but also retains the hand-written <h2>Alice is awesome</h2> line

• Go to the root folder of the repository
• Run mvn clean package to build the project
• Run java -jar target/intred.jar -rf json to run the benchmarks and produce a JSON file with the results
  • The produced JSON file can be visualised in https://jmh.morethan.io
• To run each benchmark just once (e.g. to get a quick estimate of its execution time), use the following command

java -jar target/intred.jar -rf json -f 1 -wi 0 -i 1

• To run a specific benchmark just once, use the following command

java -jar target/intred.jar 'intred.benchmarks.IntredBenchmarks.intredTransformationWithChangesBenchmark' -rf json -f 1 -wi 0 -i 1

• Run the regularEglTransformationBenchmark and the intredTransformationBenchmark together

java -jar target/intred.jar  'intred.benchmarks.IntredBenchmarks.intredTransformationBenchmark' 'intred.benchmarks.IntredBenchmarks.regularEglTransformationBenchmark' -rf json -f 2 -wi 3

• Run the intredTransformationWithChangesBenchmark on its own

java -jar target/intred.jar  'intred.benchmarks.IntredBenchmarks.intredTransformationWithChangesBenchmark' -rf json -f 2 -wi 3
