objectionary/sandbox

A simple EO program together with an environment to compile and run it

You can play with EOLANG here, in a few simple steps:

First, clone this repo to your local machine and go to the sandbox directory (you will need Git installed):

$ git clone https://github.com/objectionary/sandbox
$ cd eo/sandbox

Then, compile the code (you will need Maven 3.3+ and Java SDK 8+ installed):

$ mvn clean compile

Intermediary *.xml files will be generated in the target directory (it will be created). Also, there will be *.java and *.class files. Feel free to analyze them: EO is parsed into XML, then translated to Java, and then compiled by Java SDK to Java bytecode. Finally, just run the bytecode program through JRE:

$ ./run.sh 9
9th Fibonacci number is 34

Should work. If it doesn't, submit an issue, we will fix it.

Then, you can modify *.eo files, run mvn compile to compile them again and run.sh to run it again. eo/sandbox/app.eo is the entrypoint of the program. app object will be "evaluated", when the program is run, so modify it to make changes to the program. Then, proceed with compilation and run the program again.

In Docker

If you don't have Maven or JDK installed on your system, you can compile and run the application in Docker. You must have Docker and docker-compose installed to use this method.

First, ccompile the sources using Maven in Docker container. The output of the compilation will be in the target/ directory.

$ docker-compose -p eo-lang run maven

Overriding the default command

By default, the container's command is mvn compile. You are free to override it, when running from terminal by appending the command you want to run after the service name, e.g. to run mvn clean compile use:

docker-compose -p eo-lang run maven mvn clean compile

After the compilation, the resulting Java program can be run in Docker via:

$ docker-compose -p eo-lang run app

Passing command line arguments

It is possible to pass command line arguments to the program by appending them after the container name, e.g.:

docker-compose -p eo-lang run app "Command line arguments go here" 10

sandbox's Issues

Unable to compile "Hello, world!"

While compiling this program:

+package sandbox
+alias org.eolang.io.stdout

[args...] > app
  stdout > @
    "Hello, world!\n"

I got such an error:

[ERROR] An empty sequence is not allowed as the first argument of eo:class-name()

The error message is confusing and contains too little information. What could be the problem?

Manually update eolang version to 0.34.3

EO version can't be automatically updated for some reason (#35).
Need to figure out what's problem, fix it, and update EO version in pom.xml.

	# problems of the following code: 1) It uses varargs and maybe other

The puzzle was created by @levBagryansky on 22-Jan-24.

Estimate: 30 minutes, role: DEV.

If you have any technical questions, don't ask me, submit new tickets instead. The task will be "done" when the problem is fixed and the text of the puzzle is removed from the source code. Here is more about PDD and about me.

No output testing

In github jobs we just test that eo program correctly compiled and runs without failure. But we don't test that output is correct. @yegor256 if you think that this additional check is proper to this repo I added it in #6

Increase stack size

We need to increase stack size up to 256 mb

Wrong repos in readme

Firstly, in readme suggest to clone /objectionary/eo-git. I think it should be objectionary/sandbox instead. Secondly readme suggests go to eo/sandbox/canonical but this canonical doesn't exist. I think eo/sandbox is enought.

EO version should be `0.23.15`

Don't work after eo update
