在Mac上,如何为一个python脚本创建一个拖放应用程序,其中脚本名称而不是Python在MenuBar(等)中显示？

Question

我有一个Python脚本,我想通过点击某些内容或通过删除我要打开的文件来启动.我还想避免令人讨厌的mac Python问题,即解释器(Python)的名称而不是脚本的名称.我不想使用py2app,因为我不想捆绑Python并希望python文件保留为文本文件.我想要一个纯Python(或最好的shell脚本解决方案.)这显示了如何做所有事情,但拖放部分; 这显示了如何通过创建一个包来控制图标.

Answer 1

我对我的问题有了答案，但我希望有人能提出一些不太复杂的答案。我想出的解决方案是使用 Python 脚本来创建 AppleScript（呃！），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。

在启动 wxpython 脚本时，如果没有 AppleScript（或使用 py2app），我没有找到一种方法可以让拖放工作，并且我无法让 AppleScript 在我创建的包中工作，我必须使用 osacompile 来创建给我的捆绑包。

我更喜欢这里或这里的方法，其中“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.

有没有人有更好的方法来做到这一点而不使用 py2app？
