Add New Language

1. Choose an appropriate Docker image, write test code files, and build a custom Dockerfile that contains at least the following:

   Why Code for test needed？Refer to How To Be Safe? #3

   FROM xx:version # Base Image
   
   # Follow 3 steps are necessary
   WORKDIR /code
   COPY test.xx .
   RUN mkdir languageName # eg.py/java/c
   
   CMD ["bash"]
   

2. Configuration:

   Config config = new Config(ModeEnum.CLASSIC)
     .addLang(languageName,languageFileName,imageName,testCommand,testResult)
   	...
   

   Among them:

   Parameter Name	Meaning
   languageName	languageName in 1st step, as the first parameter of runCode method.
   languageFileName	The code file name created, requires special attention to the main class name problem for Java language.
   imageName	Image Name built in 1st step.
   testCommand	Commands for test.
   testResult	Expected results of the test for normal execution.

Example：DJudger Default C++ Configuration

1. File Preparation：

   • Dockerfile

     FROM gcc:9.4
     
     WORKDIR /code
     COPY test.cpp .
     RUN mkdir c # must be identical with languageName
     
     CMD ["bash"]
     

   • Code for test

     #include<iostream>
     using namespace std;
     int main(){
     	cout<<"Pass"<<endl;
     }
     

2. Build Image：

   cd containers/c
   sudo docker build -t judger_c .
   

3. Configuration：

   Config config = new Config(ModeEnum.CLASSIC)
     .addLang("c","main.cpp","judger_c","g++ test.cpp&&./a.out","Pass")
