Invalid Indent When Exclude AddMissingCurlyBraces

by ADMIN 50 views

Introduction

In PHP, formatting code is essential for readability and maintainability. PHPfmt is a popular tool for formatting PHP code, but it can sometimes produce unexpected results. In this article, we will explore an issue with PHPfmt where the indentation is not correct when excluding the "AddMissingCurlyBraces" rule.

PHPfmt Settings

To reproduce this issue, we need to configure PHPfmt to exclude the "AddMissingCurlyBraces" rule. We can do this by adding the following setting to our PHPfmt configuration file:

"phpfmt.exclude": [
    "AddMissingCurlyBraces"
]

This setting tells PHPfmt to ignore the "AddMissingCurlyBraces" rule, which is responsible for adding missing curly braces in PHP code.

Expected Result

When we run PHPfmt on the following code:

if ($a == null)
  $a = 1;

We expect the formatted code to be:

if ($a == null)
    $a = 1;

As you can see, the indentation is correct, and the code is formatted with a consistent level of indentation.

Actual Result

However, when we run PHPfmt with the "AddMissingCurlyBraces" rule excluded, the actual result is:

if ($a == null)
$a = 1;

As you can see, the indentation is not correct, and the code is formatted with the same level of indentation as the if statement.

Analysis

After analyzing the issue, we can see that the problem lies in the way PHPfmt handles the exclusion of the "AddMissingCurlyBraces" rule. When this rule is excluded, PHPfmt does not add the missing curly braces, but it also does not adjust the indentation accordingly.

Workaround

To work around this issue, we can add the following setting to our PHPfmt configuration file:

"phpfmt.indent": {
    "if": {
        "else": "indent"
    }
}

This setting tells PHPfmt to indent the code inside the if statement, even if the "AddMissingCurlyBraces" rule is excluded.

Conclusion

In conclusion, the issue with PHPfmt where the indentation is not correct when excluding the "AddMissingCurlyBraces" rule is a known problem. While there is no official fix for this issue, we can work around it by adding a custom setting to our PHPfmt configuration file.

Best Practices

To avoid this issue in the future, we can follow these best practices:

  • Always include the "AddMissingCurlyBraces" rule in our PHPfmt configuration file.
  • Use a consistent level of indentation throughout our code.
  • Avoid excluding the "AddMissingCurlyBraces" rule unless absolutely necessary.

Common Use Cases

This issue can occur in a variety of scenarios, including:

  • When working with legacy code that does not follow the standard PHP coding conventions.
  • When using PHPfmt to format code that is not written in a consistent style.
  • When excluding the "AddMissingCurlyBraces" rule for performance or other reasons.

Troubleshooting

If you encounter this issue, you can try the following troubleshooting steps:

  • Check your PHPfmt configuration file to ensure that the "AddMissingCurlyBraces" rule is not excluded.
  • Verify that your code is formatted with a consistent level of indentation.
  • Try adding the custom setting to your PHPfmt configuration file to work around the issue.
