go-code-runner, v1.2

The library that implements the compiling and running of a code written in the Go programming language and running of a test case set for the compiled code (i.e. the executable file).

Checking of package imports used in the code written in the Go programming language.

Change Log

• checking of package imports used in the code written in the Go programming language:
  • checking based on the list of allowed imports;
• compiling of a code written in the Go programming language:
  • checking of package imports used in the code (optionally):
    • checking based on the list of allowed imports.

Features

• saving of a code to a temporary file:
  • storing of the temporary file with the code to an individual temporary directory;
• checking of package imports used in the code written in the Go programming language:
  • checking based on the list of allowed imports;
• compiling of a code written in the Go programming language:
  • automatic importing of the packages used in the code;
  • checking of package imports used in the code (optionally):
    • checking based on the list of allowed imports;
  • enriching of an error of the external command running by an output from the stderr stream;
• running of the compiled code (i.e. the executable file):
  • passing of a custom input as the stdin stream;
  • returning of an output from the stdout stream;
  • enriching of an error of the external command running by an output from the stderr stream;
• running of a test case set for the compiled code (i.e. the executable file):
  • representation of a test case:
    • input;
    • expected output;
  • checking of an actual output in each test case:
    • returning of the sentinel errors:
      • failed running — it returns on a running error;
      • unexpected output — it returns when the expected and actual outputs do not match.

Examples

coderunner.CheckImports (success):

package main

import (
    "fmt"
    "log"
    "os"
    "path/filepath"

    coderunner "github.com/thewizardplusplus/go-code-runner"
)

func main() {
    const code = `
        package main

        import (
            "fmt"
            "log"
        )

        func main() {
            var x, y int
            if _, err := fmt.Scan(&x, &y); err != nil {
                log.Fatal(err)
            }

            fmt.Println(x + y)
