go-judge

A go package which (compiles and) executes a program and checks it with given of inputs. This can be used to build an online judge (or a web IDE).

Supported Languages

• C++
• Python 3
• Python 2

package main

import (
  "fmt"
  gojudge "github.com/vn-ki/go-judge/judge"
)

func main() {
  judge := gojudge.GetCPPJudge(gojudge.Config{})
  judge.AddSourceFile("a.cpp")
  judge.AddInputFile("input1.txt")
  
  out, err := judge.Output()
  
  if err != nil {
    panic(err)
  }
  
  fmt.Println(out)
}

You can remove the use of AddSourceFile and AddInputFile by using Config.

judge := gojudge.GetCPPJudge(gojudge.Config{
  SourceFile: "a.cpp",
  InputFiles: []string{"input1.txt"},
})

See documentation for more info on Judge.

How to add more languages

• Make a new file under go-judge/judge in the following format

package judge

/*
GetLanguageRunner returns a Runner with Language configuration
*/
func GetLanguageRunner(config Config) Judge {
	return addConfig(
    Judge{
      compileCmd:       "LanguageCompiler",
      compileArgs:      []string{"--compile-lang", "{source_file}"},
      runCmd:           "./{compiled_program}",
      runArgs:          []string{},
      compileBeforeRun: true,
      extension:        ".lang",
	  }, config)
}

• Profit!!

TODO
