How Can I Handle User Input in Sublime Text for Python Scripts?

Addressing Input Handling Challenges in Sublime Text

Sublime Text is widely used for code editing, but it lacks the native ability to process user input via functions like raw_input() in Python. This limitation can be frustrating for those who rely on input within their scripts.

Using SublimeREPL for Input Handling

One solution is to install the SublimeREPL package through Package Control. This package allows you to send code snippets to a running REPL (read-eval-print loop), effectively enabling input handling. However, it may require manual adjustments to the build files to ensure compatibility.

Creating a Custom Build System for Input

If SublimeREPL doesn't fit your needs, you can create your own custom build system that allows input. Here's how:

For Windows:

{
    "cmd": ["start", "cmd", "/k", "c:/python38/python.exe", "$file"],
    "selector": "source.python",
    "shell": true,
    "working_dir": "$file_dir",
    "env": {"PYTHONIOENCODING": "utf-8"}
}

For macOS:

{
    "shell_cmd": "osascript -e 'tell app \"Terminal\" to do script \"cd $file_path & python3 -u $file\"'",
    "working_dir": "$file_path",
    "selector": "source.python",
    "env": {"PYTHONIOENCODING": "utf-8"}
}

For Linux:

{
    "shell_cmd": "gnome-terminal --working-directory=$file_path -- bash -c 'python3 -u \"$file\" & read -n 1 -s -r'",
    "working_dir": "$file_path",
    "selector": "source.python",
    "env": {"PYTHONIOENCODING": "utf-8"}
}

Save these build systems as .sublime-build files in the Sublime Text Packages/User directory.

Using Terminus Plugin for Input Handling

Another option is to utilize the Terminus plugin. It provides a platform-independent replacement for the default build system engine. With Terminus, you can interact with your running program in a build panel below your code. Here's a sample build system for Python:

{
    "target": "terminus_exec",
    "cancel": "terminus_cancel_build",
    "cmd": [
        "/path/to/python", "-u", "$file"
    ],
    "working_dir": "$file_path",
    "file_regex": "^[ ]*File \"(...*?)\", line ([0-9]*)&\"",
}

Remember to adjust the path to your Python executable.

By employing these solutions, you can overcome the input handling limitations of Sublime Text and enhance your script-building experience.
