Flask and Sublime Text Integration: Python web application development tips (Part 6)

Both Sublime Text and Flask are important tools in Python web application development. However, how to integrate the two to make the development process more efficient? This article will introduce some Sublime Text plug-ins and configuration techniques to help you develop Flask applications more conveniently.

1. Install the Sublime Text plug-in

1. Flask plug-in

By installing the Flask plug-in, you can automatically complete the Flask framework in the Sublime Text editor code. Select Preferences > Package Control in the Sublime Text menu, search for "Flask" and install the plug-in.

2. SublimeCodeIntel plug-in

Installing the SublimeCodeIntel plug-in can automatically prompt and complete Python codes, and also supports multiple languages, including JavaScript, HTML, CSS, etc. Again, select Preferences > Package Control in the menu, search for "SublimeCodeIntel" and install the plug-in.

3. DocBlockr Plugin

DocBlockr plugin makes it easy to write documentation comments. Select Preferences > Package Control in the menu, search for "DocBlockr" and install the plug-in.

2. Sublime Text configuration

1. Installing Python interpreter

Sublime Text needs to be used in conjunction with the Python interpreter. Therefore, you need to install the Python interpreter first.

2. Configuring Build System

In Sublime Text, Build System can help you run Python scripts and view the output. Press Ctrl Shift B to select Python as the Build System so you can run the Flask application in Sublime Text.

3. Configure Sublime Text project

Create a project in Sublime Text and select Project > Edit Project. Add the following code to the file:

{
"folders":
[

{
  "follow_symlinks": true,
  "path": "."
}

],
"settings":
{

"python_interpreter": "path/to/python",
"python_interpreter_path": "path/to/python"

}
}

Replace "path/to/python" with your own Python interpreter path. In addition, you also need to modify "path" to point to the path of the Flask application.

4. Configuring Sublime Text environment variables

If you use a Python virtual environment in your Flask application, you can set environment variables in Sublime Text. Select Tools > Build System > New Build System in the Sublime Text menu and add the following code:

{
"cmd": ["source", "path/to/virtualenv/bin/activate ", "&&", "python", "-u", "$file"],
"shell": true,
"working_dir": "$project_path",
"env": { "PYTHONIOENCODING": "utf-8"}
}

Replace "path/to/virtualenv" with the path of your own virtual environment.

Summary

With the above configuration and plug-ins, you can develop Flask applications in Sublime Text more easily. Utilize the auto-prompt and auto-completion functions to greatly improve coding efficiency, and it is also more convenient to run and debug Flask applications.
