DDR is an Experimental Dynamic Dispatch Removal Toolkit for EO Programs

Launch

Using Maven

Just add this to your pom.xml

<dependency>
  <groupId>org.eolang</groupId>
  <artifactId>ddr</artifactId>
  <version>0.0.5</version>
</dependency>

And then you'll be able to use the tool like this:

CombinerKt.launch("${PATH_TO_YOUR_DIRECTORY}");

From IntelliJ Idea

You can launch the tool from IntelliJ Idea using MainKt configuration.
Just click Edit configuration in the 'Edit run/debug configurations' dialog and type an absolute path to your input directory with .xmir files in the Program arguments field.

After the execution a new directory named ${YOUR_DIRECTORY_NAME}_ddr will be created near your directory.

From console

Use these commands to launch the tool from console

$ mvn clean install
$ java -jar target/ddr-1.0-SNAPSHOT-jar-with-dependencies.jar "${PATH_TO_YOUR_DIRECTORY}"

Tests

How to add integration tests:

1. Add your directory with .eo source files to src/test/resources/integration/in.
   Note that directory name must be written in snake case.

2. Add your directory with desired output .eo files to src/test/resources/integration/out.
   Note that .eo files in the output directory must use dot notation like shown below:

[] > greet
  QQ
  .io
  .stdout > @
    "Hello, world!"

3. Add a test to ResolverTest.
   Your test name must be identical to your added directory name with _ symbols replaced with spaces and a word test inserted in the beginning.
   Example:
   Directory name: basic_example
   Test:

@Test
fun `test basic example`() = doTest()

If your tests don't pass - you can take a look at temporary files in src/test/resources/integration/eo_outputs directory. It should be more convenient for you, because you will have all your actual .eo files located there.

That's it :)
