guesslang-experimental 2.2.3

Detect the programming language of a source code

This is NOT A TYPOSQUATTING PACKAGE

It's a fork of the original https://github.com/yoeo/guesslang / pypi package guesslang

Reason of fork - abandoned project. I need a specific patch. Fixing tensorflow dependency myself until https://github.com/yoeo/guesslang/pull/62 is merged

Install:

pip install guesslang-experimental

Guesslang

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

# ⟶ Programming language: Go

Guesslang supports 54 programming languages:

Apps powered by Guesslang

Microsoft Visual Studio Code, automatic language detection

Visual Studio Code detects the programming language of the source code that you paste into the editor using Guesslang machine learning model.

Chameledit

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

Documentation

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

• Guesslang language detection explained here https://guesslang.readthedocs.io/en/latest/contents.html#how-does-guesslang-guess

• Guesslang is based on Tensorflow machine learning framework

Installation

• Python 3.7+ 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

Guesslang command line

• Show all available options

guesslang --help

• Detect the programming language of /etc/bashrc configuration file:

guesslang /etc/bashrc

# ⟶ Programming language: 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

# ⟶ Programming language: Scala

• Show the detection probabilities for a given source code:

echo "
def qsort(items):
    if not items:
        return []
    else:
        pivot = items[0]
        less = [x for x in items if x <  pivot]
        more = [x for x in items[1:] if x >= pivot]
        return qsort(less) + [pivot] + qsort(more)


if __name__ == '__main__':
    items = [1, 4, 2, 7, 9, 3]
    print(f'Sorted: {qsort(items)}')

Guesslang Python package

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

from guesslang import Guess


guess = Guess()

name = guess.language_name("""
    % Quick sort

    -module (recursion).
    -export ([qsort/1]).

    qsort([]) -> [];
    qsort([Pivot|T]) ->
          qsort([X || X <- T, X < Pivot])
          ++ [Pivot] ++
          qsort([X || X <- T, X >= Pivot]).
