Hi.

As feature request, I want php-cs-fixer support.

Like cs2pr https://github.com/staabm/annotate-pull-request-from-checkstyle,
checkstyle support would be get benefit as portable for other static analysis tool.

checkstyle support would be get benefit as portable for other static analysis tool.

I noticed, php-cs-fixer would not print Line Number.
PHP-CS-Fixer/PHP-CS-Fixer#3601

So, currently we could not support php-cs-fixer simply via checkstyle.

$ vendor/bin/php-cs-fixer fix src/Person.php --dry-run --diff --rules=@PSR12 --format=checkstyle
Loaded config default.
Using cache file ".php-cs-fixer.cache".
<?xml version="1.0" encoding="UTF-8"?>
<checkstyle>
  <file name="src/Person.php">
    <error severity="warning" source="PHP-CS-Fixer.braces" message="Found violation(s) of type: braces"/>
  </file>
</checkstyle>

line number could be get only with --diff

$ vendor/bin/php-cs-fixer fix src/Person.php --dry-run --diff --rules=@PSR12 --format=xml 1>&2 2> /dev/null
<?xml version="1.0" encoding="UTF-8"?>

Hi @sasezaki thanks for the feature request and for links to research you've already done. I'm not sure I'll be able to add this due to issue that php-cs-fixer does not supply line number. We might have to wait until there is support from the php-cs-fixer before progressing.

I'll take a bit more of a look at this and the diffs later this evening (I'm on UK time).

Without line numbers it is not going to be possible to implement this. The relevant issue is PHP-CS-Fixer/PHP-CS-Fixer#3601

If a PR for this, or a similar PR that adds line numbers to an output gets merged then I'll happily create a ResultsParser for the format.

For now I'll close this issue.
