我有一个 Python 脚本,我想通过点击某个东西或拖放一个我想在那个东西上打开的文件来启动它。我还想避免烦人的 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。)This展示了如何做所有事情,但拖放部分除外; this展示了如何通过创建一个包来实现同样的目的,它允许一个人控制图标。

最佳答案

我的问题有了答案,但我希望有人能想出不那么复杂的东西。我想出的解决方案是一个 Python 脚本来创建一个 AppleScript(呃!),将其编译成一个包,然后修改该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,我没有找到使拖放工作正常的方法,而且我无法让 AppleScript 在我创建的包中工作,我不得不使用osacompile 为我创建包。

我更喜欢这种方法 herehere ,其中一个人“手动”创建 plist 文件,而不是像我在这里所做的那样修改外部创建的文件,但下面的脚本确实完成了这项工作。

#!/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.
'''
import sys, os, os.path, stat, shutil, subprocess, plistlib

try:
subprocess.check_output(["osacompile","-o",apppath,shell],stderr=subprocess.STDOUT)
except subprocess.CalledProcessError, msg:

print msg.output
sys.exit()

# create a link to the python app, but named to match the project
os.symlink(pythonapp,newpython)

# change the icon
oldicon = os.path.join(apppath,"Contents","Resources","droplet.icns")
if os.path.exists(iconfile) and os.path.exists(oldicon):
shutil.copyfile(iconfile,oldicon)

# Edit the app plist file to restrict the type of files that can be dropped
d = plistlib.readPlist(os.path.join(apppath,"Contents",'Info.plist'))
d['CFBundleDocumentTypes'] = [{
'CFBundleTypeExtensions': allowedfiletypes,
'CFBundleTypeName': allowedtypedesc,
'CFBundleTypeRole': scripttype}]
plistlib.writePlist(d,os.path.join(apppath,"Contents",'Info.plist'))

print("\nCreated "+project+" app ("+str(apppath)+
").\nViewing app in Finder so you can drag it to the dock if, you wish.")
subprocess.call(["open","-R",apppath])

有没有人有更好的方法在不使用 py2app 的情况下做到这一点?
