StopCoding: An IntelliJ IDEA Plugin to Prevent Coding Fatigue – Installation, Usage, and Development Guide

Preface

The author, motivated by personal health concerns caused by long coding sessions, decided to create an IntelliJ IDEA plugin named StopCoding that periodically shows a non‑dismissable reminder dialog with a countdown, forcing the user to take a break.

Installation and Usage Tutorial

Installation

Search for "StopCoding" in the IDEA plugin marketplace and install it (the plugin has passed official review).

For internal network users, download the plugin package from the provided link and install it locally.

Usage

Step 1: Open Tools → StopCoding from the menu bar.

Step 2: Configure the desired interval and other parameters, then save.

Step 3: Continue coding; when the interval elapses, an unclosable dialog appears with a rest countdown that only disappears after the break is completed.

Development Tutorial

The plugin is built with basic Java knowledge, using Swing for UI and java.util.Timer for scheduling.

Technical Scope

Plugin project structure

Swing for two dialog interactions

Timer as the core scheduling component

Plugin Project Structure

Key files and directories include:

plugin.xml : core configuration file.

data : contains SettingData (configuration model) and DataCenter (static runtime data).

service : includes TimerService (core timer logic).

task : defines RestTask (break timer) and WorkTask (work timer).

ui : holds UI components such as SettingDialog (settings dialog) and TipsDialog (break reminder dialog).

StopCodingSettingAction : entry point action that launches the plugin.

Swing

Creating Swing dialogs in IDEA is straightforward thanks to visual designers; the article outlines the three‑step process of building a dialog and adding events.

Creating the Dialog

Step 1 – design the dialog layout; Step 2 – configure component properties; Step 3 – finalize the dialog.

Adding Event Listeners

The generated dialog already includes OK and Cancel buttons with listeners. Custom listeners can be added to any component. Example code:

public class TestDialog extends JDialog {
    private JPanel contentPane;
    private JButton buttonOK;
    private JButton buttonCancel;

    public TestDialog() {
        setContentPane(contentPane);
        setModal(true);
        getRootPane().setDefaultButton(buttonOK);

        buttonOK.addActionListener(new ActionListener() {
            public void actionPerformed(ActionEvent e) {
                onOK();
            }
        }); // OK button listener

        buttonCancel.addActionListener(new ActionListener() {
            public void actionPerformed(ActionEvent e) {
                onCancel();
            }
        }); // Cancel button listener
        // other code
    }
}

Timer Scheduler

The plugin uses the standard JDK Timer to schedule work and rest intervals. Common APIs such as constructor, schedule , and cancel are demonstrated with screenshots.

Conclusion

With the provided overview, readers can explore the source code (https://github.com/jogeen/StopCoding) and build their own productivity‑enhancing IDEA plugins. The author hopes the plugin helps programmers maintain healthier work habits.
