Guesslang detects the programming language of a given source code:

echo '
package main
import "fmt"

func main() {
    fmt.Println("My mascot is a gopher and Google loves me. Who am I?")
}

' | guesslang

# Output: The source code is written in Go

Guesslang supports 20 programming languages:

With a guessing accuracy higher than 90%.

Chameledit is a simple web-editor that automatically highlights your code.

Pasta is a Slack bot that pretty pastes source code.

GG is a silly guessing game.

• Guesslang documentation is available at https://guesslang.readthedocs.io/en/latest/

• Guesslang language detection explained here https://guesslang.readthedocs.io/en/latest/how.html

• Guesslang is based on Tensorflow machine learning framework

• Python 3.6+ is required

• Install the latest stable version:

pip3 install guesslang

• or install Guesslang from source code:

pip3 install .

• Windows specific

To run Tensorflow on Microsoft Windows you need to install Visual C++ runtime libraries, available on Microsoft website

• Show all available options

guesslang --help

• Detect the programming language of /bin/which:

guesslang -i /bin/which

# >>> The source code is written in Shell

• Detect the programming language of a given text:

echo '
/** Turn command line arguments to uppercase */
object Main {
  def main(args: Array[String]) {
    val res = for (a <- args) yield a.toUpperCase
    println("Arguments: " + res.toString)
  }
}
' | guesslang

# >>> The source code is written in Scala

• Detect the programming languages of a source code that embeds an other source code (sourcecodeception):

echo '
from __future__ import print_function


def dump_code(code):
  print(code)


if __name__ == "__main__":
    dump_code("""
        #include<stdio.h>

        int main(int argc, char** argv)
        {
          char* command = argv[0];
          printf("%s - %d args\n", command, --argc);
          return 0;
        }
    """
    )

' | guesslang --all

# >>> The source code is written in Python or C

• Guesslang can be used as a Python package. Package documentation available here
