如何在 Python 脚本中访问 Atom 工作区目录

Question

I was working on a Python script, and wanted to access Atom's current working directory in that script.

Atom is built on electron.js, and the way you do it in JavaScript is:

let filePath = atom.workspace.getActiveTextEditor().getPath();

I want this variable (simply the directory) in my Python script instead.

The idea of what you're trying to achieve is giving me some headaches. While it's certainly possible to invoke the Python interpreter from JavaScript, it's probably not the best user experience for people using your package.

Before even running the Python script, the package needs to check at least the following:

• user has the correct version of Python installed
• python is exposed to the PATH
• the active file is eligible to be interpreted by Python

These are different problems, but nevertheless some you need to sort out.

You haven't specified, whether you invoke the Python script within a synchronous or asynchronous function. I'm going to assume the former since it's easier to follow for JavaScript beginners, but you might want to change that in a later step

JavaScript

// Import Node's spawn method
const { spawnSync } = require('child_process');

// Get path of active file
const activeEditorPath = atom.workspace.getActiveTextEditor().getPath();

// Spawn child process
const child = spawnSync('python', ['path/to/your/script', activeEditorPath]);

Python

import sys

# Get argument
active_editor_path = sys.argv[1]

# Print editor path
print(f'Active editor path: {active_editor_path}')
