VSCode Line at 80 Characters: Maintaining Code Readability and Best Practices

When it comes to writing clean and readable code, adhering to some common code styling practices is crucial. One such practice is setting a line length limit, commonly referred to as keeping code lines at 80 characters or less. This article will guide you through setting up this line length limit in Visual Studio Code (VSCode) and provide insights into why it is important for your projects. Additionally, we will discuss various tools and techniques that can help you enforce and handle the 80-character line limit effectively.

Setting Up the Line Length Limit in VSCode

By default, VSCode does not enforce any specific line length limit. However, you can configure this limit yourself to ensure your code follows the recommended practices. To set up the line length limit in VSCode, you can use the “EditorConfig” extension, which provides a convenient way to define and maintain consistent code styles across multiple developers and projects.

Configuring the Default Line Length Limit in VSCode

Once you have the EditorConfig extension installed, create an `.editorconfig` file in the root directory of your project. In this file, you can specify the desired line length limit by adding the following line:

“`
[*]
max_line_length = 80
“`

This configuration will apply the 80-character line limit to all files within your project. You can customize this limit by changing the value accordingly.

Using the EditorConfig Extension in VSCode

The EditorConfig extension in VSCode recognizes the configurations specified in your `.editorconfig` file. It automatically adjusts the indentation, line endings, and other formatting settings to match the defined rules. This seamless integration allows you and your team to maintain consistent code styles without any manual effort.

Choosing the Right Line Length Limit for Your Project

While the recommended line length limit is typically set at 80 characters, it is essential to consider the specific requirements and circumstances of your project. Longer line limits may be suitable for specific languages or frameworks that require extensive comments or lengthy function signatures. However, it is generally advisable to keep the line length within a reasonable limit to avoid horizontal scrolling and readability issues.

Working with Code Linters in VSCode

Code linters are powerful tools that help you identify and fix code quality issues, including line length violations. In VSCode, you can integrate a code linter like ESLint or Prettier to enforce the line length limit dynamically as you write code.

Enforcing the Line Length Limit with ESLint

ESLint is a popular JavaScript linter that provides a wide range of rules to enforce code quality. To enforce the line length limit using ESLint, integrate it into your project and configure the `max-len` rule in the `.eslintrc` file.

“`JSON
{
“rules”: {
“max-len”: [“error”, { “code”: 80 }]
}
}
“`

By setting the `code` option to 80, you ensure that ESLint reports an error whenever a line exceeds the specified character count.

Enforcing the Line Length Limit with Prettier

Prettier is an opinionated code formatter that supports various programming languages. While Prettier does not have a dedicated rule for line length, it automatically wraps code lines at the specified character limit defined in your `.editorconfig` file or other formatting configurations.

Handling Long Lines in VSCode

Despite your best efforts, it is possible that occasionally you may encounter long lines that exceed the defined line length limit. In such cases, VSCode provides helpful features to handle these situations effectively.

Auto Break Line in VSCode

To break long lines automatically in VSCode, simply enable the “Auto Indent” option. This setting will automatically wrap lines when you reach the line length limit, making your code more readable and preventing violations.

Add Ruler to VSCode

The “Ruler” feature in VSCode allows you to add visual indicators at specific character positions on your editor window. To do so, press `Cmd/Ctrl + Shift + P` to open the command palette, type “Preferences: Open Settings (JSON),” and add the following configuration:

“`JSON
“editor.rulers”: [80]
“`

This configuration adds a vertical line at the specified column position (in this case, column 80) to help you ensure that your lines do not exceed the recommended limit.

Hide Vertical Line in VSCode

In situations where the vertical line becomes distracting or unnecessary, you can easily hide it by setting the `editor.rulers` value to an empty array in your `settings.json` file:

“`JSON
“editor.rulers”: []
“`

Searching for Lines in VSCode

If you need to find lines that exceed the desired character count, you can make use of VSCode’s built-in features. Use the default keybinding `Ctrl + F` to open the search bar, enter a regular expression, and set the “Find” input to `.{81,}` to find lines with more than 80 characters.
