How do I create a jar using armed bear common lisp?

问题

I was wondering if it's possible to create a jar file using armed bear common lisp and if so how to do it.

So in other words, I have this following code (format t "Hello, World!~%")) I can run it in armed bear common lisp. I was wondering how I could create a jar that executes that code.–

Thanks,

Shaun.

The documentation says (in section 3.3, sorry for the pdf) -

3.3.2 Implemented JSR-223 interfaces

JSR-223 defines three main interfaces, of which two (Invocable and Compilable) are optional. ABCL implements all the three interfaces - ScriptEngine and the two optional ones - almost completely.

Creating an executable jar with ABCL in five easy steps

Step one: Creating a fat jar containing Armed Bear.

I'm going to use maven because it's what I know. Let's create a pom.xml file.

<project xmlns="http://maven.apache.org/POM/4.0.0"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://maven.apache.org/POM/4.0.0
   http://maven.apache.org/xsd/maven-4.0.0.xsd">
    <modelVersion>4.0.0</modelVersion>
    <groupId>com.stackoverflow.example</groupId>
    <artifactId>ColbertNightmare</artifactId>
    <version>1.0.0</version>
    <packaging>jar</packaging>
    <name>Stephen Colbert's Nightmare - Armed Bears</name>
    <dependencies>
        <dependency>
            <groupId>org.abcl</groupId>
            <artifactId>abcl</artifactId>
            <version>1.6.0</version>
        </dependency>
    </dependencies>
    <build>
        <finalName>ColbertNightmare</finalName>
        <plugins>
            <plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-compiler-plugin</artifactId>
                <version>3.8.1</version>
                <configuration>
                    <source>1.8</source>
                    <target>1.8</target>
                </configuration>
            </plugin>
            <plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-assembly-plugin</artifactId>
                <version>3.2.0</version>
                <configuration>
                    <descriptorRefs>
                        <descriptorRef>jar-with-dependencies</descriptorRef>
                    </descriptorRefs>
                    <archive>
                        <manifest>
                            <addClasspath>true</addClasspath>
                            <mainClass>com.stackoverflow.example.Main</mainClass>
                        </manifest>
                    </archive>
                </configuration>
                <executions>
                    <execution>
                        <id>make-assembly</id>
                        <phase>package</phase>
                        <goals>
                            <goal>single</goal>
                        </goals>
                    </execution>
                </executions>
            </plugin>
        </plugins>
    </build>
</project>

Step two: We need to follow the maven standard directory structure.

We will have one Java class for an entry point. In the folder containing pom.xml,

mkdir -p src/main/java/com/stackoverflow/example

If you're on Windows, you need to (instead)

mkdir src\main\java\com\stackoverflow\example

Step three: Write the Java code (in the folder we just created)

Create a Main.java file containing (note I fixed an extra ) bug in your LISP code)

package com.stackoverflow.example;

import javax.script.ScriptException;

import org.armedbear.lisp.scripting.AbclScriptEngine;
import org.armedbear.lisp.scripting.AbclScriptEngineFactory;

public class Main {
    public static void main(String[] args) {
        AbclScriptEngine scriptEngine = (AbclScriptEngine) new AbclScriptEngineFactory()
                    .getScriptEngine();
        try {
            scriptEngine.eval("(format t \"Hello, World!~%\")");
        } catch (ScriptException e) {
            e.printStackTrace();
        }
    }
}

Step four: Let's build and package our application.

In the folder containing the pom.xml,

mvn package

Step five: Run it

$ java -jar target/ColbertNightmare-jar-with-dependencies.jar
Hello, World!

Conclusion

Something like the above can be used to create an executable jar that uses ABCL. Also, Stephen Colbert warned us about bears (before they were armed). I think they're an even bigger threat now.
