使用Python脚本打开特定的文件类型吗？ [英] Open specific file type with Python script?

问题描述

如何使Python脚本成为特定文件类型的默认应用程序（例如* .foo）？例如，当我双击Finder / Explorer中的文件时，我希望在Python脚本中打开该文件。

How can I make a Python script to be a specific file type's (e.g., *.foo) default application? As in, when I double click the file in the Finder / Explorer I want the file to open in the Python script.

在Win和/或Windows中可以这样做吗？ OS X？

Is this possible to do in Win and/or OS X? The application is a PySide app if that matters.

推荐答案

Mac OS X

在 Mac OS X 上，您可以使用 Automator 创建一个应用程序，该应用程序调用您的python应用程序并将输入文件路径作为字符串参数传递。在应用程序工作流向导中，添加操作运行Shell脚本，选择传递输入：作为作为参数，然后在文本框添加：

Mac OS X

On Mac OS X you can use Automator to create an application that calls your python app and passes the input file path as a string argument. In the application workflow wizard, add action "Run Shell Script", select Pass input: as as arguments, and in the text box add:

python /path/to/my/app/myapp.py "$@"

$ @ 会传递输入（也就是所选文件）作为字符串。只要您的脚本设置为将输入（ sys.argv ）作为字符串列表处理（第一个是python应用程序路径），那么它将

The "$@" passes along whatever arguments were in the input (aka the selected file) as strings. As long as your script is set up to deal with the input (sys.argv) as a list of strings (the first one being the python app path), then it will work.

保存该Automator工作流程后，OS X会像对待其他任何应用程序一样对待它，并且可以将该应用程序设置为类型为 *的文件的默认设置.foo。要将 * .foo与该应用程序关联，请右键单击.foo文件，然后依次单击获取信息，打开...：$ ... c $ c>，选择您在Automator中创建的应用，然后单击全部更改... 按钮。

When you save that Automator workflow, it is treated by OS X like any other app, and you can set that app as the default for files of type "*.foo". To associate "*.foo" with that app, right click a .foo file, Get Info, Open with: Other..., choose the app you created in Automator, then click the Change All... button.

一种类似但希望较少涉及的方法可能在Windows中可用。您可能会创建具有以下内容的批处理文件（ .bat ）：

A similar but hopefully less-involved approach might work in Windows. You could probably create a batch file (.bat) with the following:

python C:\path\to\my\app\myapp.py %*

％* 会扩展到所有参数。

只要您可以将文件扩展名与此关联批处理文件，那么您可以这样做，那就是您的解决方案。但是，我还没有尝试过Windows解决方案，因此请带一点盐。另一方面，我已经测试了Mac解决方案。

As long as you can associate a file extension with that batch file, then you could do that, and that's your solution. However, I haven't tried this Windows solution, so take it with a grain of salt. The Mac solution, on the other hand, I have tested.
