This Maven plugin takes XMIR generated by jeo-maven-plugin and tries to transform combinations of opcode objects into EO objects.

Input:

seq > @
  opcode > NEW-187-29
    "org/eolang/ineo/A"
  opcode > DUP-89-30
  opcode > BIPUSH-16-31
    42
  opcode > INVOKESPECIAL-183-32
    "org/eolang/ineo/A"
    "<init>"
    "(I)V"

Output:

+alias org.eolang.ineo.jA

jA 42 > x
x.init

Then, it can translate declarative EO code back to imperative EO code which uses opcode atoms.

How to Use

The opeo-maven-plugin comprises two goals: decompile and compile. The decompile goal processes the output of the jeo-maven-plugin, converting it into high-level EO code. On the other hand, the compile goal processes the high-level EO code, transforming it back into low-level EO code that is compatible with the jeo-maven-plugin. Below, you will find examples demonstrating how to execute the plugin.

Direct Command

To execute the opeo-maven-plugin, you need a minimum of Maven 3.1.+ and * Java 8+* installed on your system. You can initiate the plugin from the command line with a single command. For instance, to transform the output generated by the jeo-maven-plugin into high-level EO code, you can utilize the following command:

mvn opeo:decompile

Subsequently, you can convert the high-level EO code back to low-level EO code, which is also compatible with the jeo-maven-plugin. To accomplish this, use the following command:

mvn opeo:compile

Maven Build

Another way to use the plugin is to add it directly to your pom.xml file:

<plugin>
  <groupId>org.eolang</groupId>
  <artifactId>opeo-maven-plugin</artifactId>
  <version></version>
  <executions>
    <execution>
      <id>opeo-decompile</id>
      <goals>
        <goal>decompile</goal>
      </goals>
    </execution>
    <execution>
      <id>opeo-compile</id>
      <goals>
        <goal>compile</goal>
      </goals>
    </execution>
  </executions>
</plugin>

The default phase for the both goals is process-classes.
