之前提到 py2exe 可以建立單一的 exe image,今天馬上來測試了一下,果然很好用。順便還從 sample 裡學到把 image building action 嵌到原指令稿裡的小技巧:
def main(): """ Script invokation logic. """ if len(sys.argv) > 1 and sys.argv[1] == "py2exe": setup_py2exe() sys.exit() def setup_py2exe(): from distutils.core import setup import py2exe setup( name = "programname", description = "Program Description", author = "Yung-Yu Chen", author_email = "you@guess", console = [ __file__ ], version = __version__, options = { "py2exe": {"compressed" : 1, "optimize" : 2, "ascii" : 1, "bundle_files": 1 } }, zipfile = None ) if __name__ == '__name__': main()
不過 500 行指令稿作出來的一個 win32 exe image,只用到了一些 Numeric 函式和少數的標準模組,就包出了 2.x MB ("compressed":1 !!),每次都要載入好久 :)
為了一段解譯對應檔的程式,還想了這樣子的碼:
iwant = [ origstring ] for splitter in [ ':', '=', ',', ';', None ]: newstrings = [] for substring in iwant: newstrings.extend( substring.split(splitter) ) iwant = newstrings
需要 6 行,或許有 60 分了吧;感覺上應該還有更短的寫法,把後四行代換成一行 (in Python 2.3)。re 說不定可以用一行解決 (倒是還沒時間去想)。
Fun.
