Structure

Project has two parts: manually written and auto-generated.

In src/main you may find source code. Classes listed there are not auto-generated. They describe EO language and .eo extension.

The second part is auto-generated classes. They should be generated from .g4 file and moved into src/java/org/eolang/jetbrains/parser. The grammar will be downloaded automatically during build gradle task. Needed class will be generated at the same time.

Resources (icons and plugin.xml) are located in src/resources.

We use Rultor for publishing (see .rultor.yml).

How it Works

Plugin is implemented in Java and ANTLR4 grammar.

ANTLR4 adapter is used for generating EOLexer and EOParser classes.

Compiling EO sources using plugin

In order to compile eo sources withing the project it must be maven project. Its pom file should contain eo-maven-plugin configuration as follows:

<build>
    <plugins>
      <plugin>
        <groupId>org.eolang</groupId>
        <artifactId>eo-maven-plugin</artifactId>
        <version>0.27.0</version>
        <configuration>
          <foreign>${project.basedir}/target/eo/foreign.csv</foreign>
          <foreignFormat>csv</foreignFormat>
          <hash>master</hash>
          <failOnWarning>true</failOnWarning>
        </configuration>
      </plugin>
    </plugins>
  </build>

Having this set up compilation can be triggered by Build -> EO compile menu action.
