簡化Cython編譯的Script

在CPython當中，我們可以透過Cython的技術，將Python程式碼加以編譯來保護程式碼，並加速程式的執行。一般作法需要另外準備setup.py，並透過命令列來加以編譯。為了簡化步驟，我寫了以下的script。在Anaconda Spyder執行該script，隨即跳出檔案選擇視窗。選擇要編譯的.pyx檔即可生成.pyc檔。

import os import tkinter as tk from tkinter import filedialog root = tk.Tk() root.withdraw() pyx_path = filedialog.askopenfilename(initialdir = "d:/demo", title = "Select file", filetypes = (("pyx files","*.pyx"), ("all files","*.*"))) pyx_dir = os.path.dirname(pyx_path) os.chdir(pyx_dir) pyx_name = os.path.basename(pyx_path) setup = '''from distutils.core import setup from Cython.Build import cythonize setup(name='', ext_modules=cythonize("{}"))'''.format(pyx_name) with open('setup.py', 'w') as f: f.write(setup) os.environ['path']+=';C:\ProgramData\Anaconda3' os.system('python setup.py build_ext --inplace') os.startfile(pyx_dir)
