Codetask Parser for the HTWG-Konstanz learning platform

A Scala Parser using "Scala Parser Combinators" for the HTWG-Konstanz learning platform codetask.

Build status:

Development

For the development you will need the docker-compose tool. To start the server in development mode, you have to start the docker container:

docker-compose up -d

It will start a play and a ngrok container. Where play is the Play Framework server and ngrok is the server where Ngrok service is running. (Ngrok is used to link your local server to the internet, so github is able to send events to your local server)

To run the play server follow the commands:

# start bash in the play container
docker-compose exec play bash

# start local server
sbt run

Deployment

Building the parser library

# change directory
cd lib

# packaging the library
sbt package

After the commands have been executed, a library jar file is located in the subdirectory target/scala-x.y (where x.y is the Scala version).

Building the automation server

First, copy the previously generated parser library jar file into the lib (project/lib) directory of the project.

The following commands should then be executed:

# change directory
cd project

# build production version
sbt dist

After the commands have been executed, a build zip file for production is located in the subdirectory target/universal.

Running on the server

You can now copy the zip file to the desired server and unpack it. After the zip-file has been unpacked, the server can be started:

# change directory
cd bin

# start server
./codetask-parser

Production configuration

Create a configuration file e.g prod.conf. The following configuration must be made:

include "application.conf"

play.http.secret.key=...
users.key=...
firebase.database="..."
github.key=...
github.clientId=...
github.clientSecret=...

Where play.http.secret.key Play Framework key to secure the server. User and Github keys are the keys useed to access the user and github links on the webserver. Firebase is the link to the database. Github client id and client secret are the oauth keys from github. These are used for exceeding the limit of the requests.

After that you can start the server with the created configuration as follows:

# start server with the created configuration
./codetask-parser -Dconfig.file="<path to the conf file>/prod.conf"

IMPORTANT: If the server was previously closed by a kill, the RUNNING_PID file in the root directory must be deleted.

Github-Webhook

Now you can set up the webhook for the desired repository. To do this, go to Settings in the repository and select Webhooks. Click on Add Webhook in the upper right corner, enter Url and set content type to json. At the end click on Add Webhook to create it.
