PhpStorm中YAML序列缩进异常问题——寻求.editorconf配置解决方案

First, let's break down your issue: PhpStorm's auto-formatting is adjusting the indentation of YAML sequences that contain nested mappings (key-value pairs), which doesn't match your project's established old format. While your current .editorconfig covers basics like encoding and quotes, it's missing rules specific to YAML sequence indentation.

Step 1: Update Your .editorconfig #

.editorconfig does support some YAML-specific formatting properties that can help align PhpStorm's behavior with your project's standards. Add these lines to the [*.yaml] section of your config:

[*.yaml]
quote_type = single
indent_style = space
indent_size = 4
yaml_indent_sequence_values = false  # Prevents indenting nested mappings under sequence dashes
yaml_align_key_values = false         # Optional: Disable key alignment if your old format doesn't use it

• yaml_indent_sequence_values = false is the key here: it tells PhpStorm not to indent the mappings inside a sequence relative to the - symbol, keeping them aligned with the sequence marker (matching your project's old format).
• yaml_align_key_values is useful if your project doesn't align colons across key-value pairs, which is common in many YAML styles.

Step 2: Fall Back to PhpStorm's Built-in Settings #

If .editorconfig alone doesn't fix the issue (some YAML formatting rules aren't fully covered by .editorconfig), you'll need to tweak PhpStorm's native YAML formatter settings:

1. Open File > Settings (or Preferences on macOS)
2. Navigate to Languages & Frameworks > YAML > Formatter
3. In the Indentation section:
   • Toggle Indent sequence values to match the yaml_indent_sequence_values setting in your .editorconfig
   • Adjust Indent nested mappings inside sequences if needed to match your old format's indentation depth
4. Check the Wrap and Braces section to ensure line wrapping behavior aligns with your project's standards

If you're still having trouble, you can import a code style profile from one of your project's correctly formatted YAML files: go to Settings > Editor > Code Style > YAML, click the gear icon, and select Import Scheme > From File to load the style from a valid old-format file.
