VS Code Config: Enforcing a Coding Style with Rulers

Why a Ruler?

In a team, respecting a code style is essential.
One of VS Code’s simple tools is the ruler: a vertical line displayed in the editor at a given column (e.g. 80 characters).

It helps you keep track of how far you write on each line: better readability, consistency between developers, following best practices.

Minimal Configuration Example

Here is a settings.json configuration for VS Code, focused on the essentials:

{
    "editor.rulers": [80],
    "workbench.startupEditor": "newUntitledFile",
    "git.autofetch": true,
    "editor.detectIndentation": false,
    "editor.renderWhitespace": "all",
    "workbench.panel.defaultLocation": "right",
    "terminal.integrated.cursorStyle": "line",
    "terminal.integrated.fontFamily": "monospace",
    "window.menuBarVisibility": "toggle",
    "diffEditor.ignoreTrimWhitespace": false
}

Quick Explanations

1. "editor.rulers": [80]
   Displays a vertical guide at column 80 → ideal for keeping code readable and consistent.
2. "workbench.startupEditor": "newUntitledFile"
   VS Code opens an empty file directly on startup → saves time, you start coding right away.
3. "git.autofetch": true
   Automatically updates remote Git information → you always see the real state of the project without a manual fetch.
4. "editor.detectIndentation": false
   Prevents VS Code from trying to “guess” indentation → the editor follows your rules, not those detected in the file.
5. "editor.renderWhitespace": "all"
   Visually displays spaces and tabs → avoids invisible style errors.
6. "workbench.panel.defaultLocation": "right"
   Places the panel (console) on the right instead of at the bottom.
   👉 If you deliberately limit yourself to 80-column lines, it’s better to keep more vertical space than horizontal space.
   This remains a personal choice; everyone adapts to their own comfort.

A Clear Style, for the Whole Team

Setting up these simple rules in VS Code helps you:

• have more readable code,
• ensure consistency between developers,
• and avoid invisible errors (spaces, inconsistent indentation).

A small tweak to your settings.json, and you lay the foundations for a shared coding style across your projects.
