在Mac上,如何为python脚本创建一个拖放应用程序,其中脚本名称而不是Python显示在菜单栏中(等)?



我有一个Python脚本,我想通过点击某个东西或删除我想打开的文件来启动它。我还想避免令人讨厌的macPython问题,即解释器的名称(Python)而不是脚本的名称。我不想使用py2app,因为我不想捆绑Python,并且希望Python文件保持为文本文件。我想要一个纯Python(或者最好是shell脚本解决方案)。这展示了如何做所有事情,但拖放部分除外;这展示了如何通过创建一个bundle来实现同样的功能,该bundle允许用户控制图标。

我的问题有答案,但我希望有人能想出一些不那么复杂的东西。我提出的解决方案是使用Python脚本创建AppleScript(ugh!),将其编译成捆绑包,然后修改捆绑包以更改允许的文件扩展名、图标等

在没有AppleScript(或使用py2app)的情况下启动wxpython脚本时,我没有找到一种方法来进行拖放操作,而且我无法在我创建的捆绑包中使用AppleScript,我不得不使用osacompile为我创建捆绑包。

我更喜欢这里或这里的方法,即"手动"创建plist文件,而不是像我在这里那样修改外部创建的文件,但下面的脚本确实可以完成这项工作。

#!/usr/bin/env python
'''This script creates an AppleScript app to launch a python script.
The app is created in the current working directory. A softlink is
made to an app version of the current python (with name
.../Resources/Python.app/Contents/MacOS/Python and found in the
directory tree of calling python interpreter), but with the name of
the app to be created, this means that the app name shows up in the
Mac menus.
Run this script with one, two or three arguments:
    <python script>
    <project name>
    <icon file>
The python script path may be specified relative to the current path
or given an absolute path, but will be accessed via an absolute path
in the AppleScript.
If the project name is not specified, it will be taken from the root
name of the script.
If the icon file is not specified, it will be assumed to be the same
as the python script, but with the extension changed from .py to
.icns.  (Note that image files can be saved in ICNS format in
Preview.). No error occurs if the icon file does not exist.

有人能在不使用py2app的情况下找到更好的方法吗?

可以通过重写wx的MacOpenFiles方法来处理应用程序图标上的文件的DnD。应用程序对象。

在lib/python2.7/plat-mac中的Python库中,有一个名为bundlebuilder.py的脚本可以用来帮助您构建应用程序包。它来自OSX的早期,在某些方面可能已经过时了,但上次我尝试它时它起了作用。
