如何使用PHPCBF一次修复一个问题？

I've added a PHPCS configuration to get some standards into a legacy project.

I'm using a relaxed version of PSR-2 as an interim step. Now what I want to do, is slowly remove the exclusions, one by one, committing the changes into Git each step of the way.

How do I go about running PHPCBF for a given configuration?

Within my ruleset, I have:

<arg name="tab-width" value="4"/>
<rule ref="PSR2">
    <exclude name="PSR1.Files.SideEffects.FoundWithSymbols"/>

    <exclude name="Generic.Files.LineLength.TooLong"/>

So, what I am asking is how I run PHPCBF for, for example, 'Generic.PHP.LowerCaseConstant.Found'.

So far I have tried the following:

   ./www/vendor/bin/phpcbf www/application --sniffs=Generic.PHP.LowerCaseConstant.Found
   ./www/vendor/bin/phpcbf www/application --sniffs=Generic.Sniffs.PHP.LowerCaseConstant.Found
   ./www/vendor/bin/phpcbf www/application --sniffs=Generic.Sniffs.PHP.LowerCaseConstantSniff
   ./www/vendor/bin/phpcbf www/application --standard=Generic --sniffs=Generic.Sniffs.PHP.LowerCaseConstantSniff
   ./www/vendor/bin/phpcbf -w www/application --standard=Generic --sniffs=Generic.Sniffs.PHP.LowerCaseConstantSniff
   ./www/vendor/bin/phpcbf -w www/application --standard=generic --sniffs=Generic.Sniffs.PHP.LowerCaseConstantSniff

None of which are correct. They just produce PHPCBF's help text.

You can only fix the errors from an entire sniff at once and not a specific error message. So you'd have to run:

./www/vendor/bin/phpcbf www/application --standard=Generic --sniffs=Generic.PHP.LowerCaseConstant

To fix all errors reported by the Generic.PHP.LowerCaseConstant sniff

I was able to run phbcbf on a specific error message within a specific sniff file by using the exclude rules like you have listed in the sample code above. You can use the xml file directly in the phbcbf command

phpcbf --standard=path_to_your_ruleset_file.xml

Trying to run phpcbf by selecting specific sniffs in the command line did not allow me to do this though.

This was the only rule that I had in the custom ruleset file

<rule ref="Drupal.Commenting.FunctionComment">
  <exclude name="Drupal.Commenting.FunctionComment.Missing"/>
  <exclude name="Drupal.Commenting.FunctionComment.MissingFile"/>
  <exclude name="Drupal.Commenting.FunctionComment.MissingParamType"/>
  <exclude name="Drupal.Commenting.FunctionComment.WrongStyle"/>
  <exclude name="Drupal.Commenting.FunctionComment.ParamCommentNewLine"/>
  <exclude name="Drupal.Commenting.FunctionComment.IncorrectParamVarName"/>
  <exclude name="Drupal.Commenting.FunctionComment.SpacingAfter"/>
  <exclude name="Drupal.Commenting.FunctionComment.SpacingAfterParamType"/>
</rule>

Do note that I did not explicitly exclude all the possible errors but instead only excluded the errors that were present in the codebase I was running this for. The only error I wanted to fix was the one I did not include in the exclude list.
