[Python ＆ PyQt] Python Loader

Download: PyQtLoader.zip
Introduction

It's wired that Python don't have the feature that can compile python code as binary file. Thus, I plan to write a simple program as python loader generator.

The technique of this program is quite low level, I just create a "c language" based binary file to execute the target python script.

Below are the core python script for this project
#! /usr/bin/python

            file.write("#include <stdio.h>\nint main(void){ system(\"python ./" + os.path.basename(self.filePath) + "\");return 0;}\n")

            os.system("gcc -o "+splitext[0]+" "+srcFileName)
            os.remove(srcFileName)

        filePath = self.ui.fileDialog_export.getOpenFileName(self, 'Open File', QtCore.QDir.homePath()+'/Desktop', "python(*.py)")

As you can see, all coding, compiling processes can be done in runtime. After the processing completed, you will see a binary file which has the same filename with your python script.

Screenshot

The usage is very very simple, just click the left-hand side's button to load your python script, and than click the 'Generate' to create the binary loader.

#For each loader, it will takes about 60 KBs of memory.
