Good morning!
I'm a soon-to-be user of the not-so-frequently used puppet-lint linter, and I've found that it has stopped working since an upstream linter change ( https://github.com/rodjek/puppet-lint/issues/539 ) removing the linenumber formatter in favor of line.
The issue is in:
arcanist/src/lint/linter/ArcanistPuppetLintLinter.php:53
Reproduction steps is making a commit to any file with the linter installed:
{ "linters": { "foo": { "type": "puppet-lint", "include": "(\\.pp$)" } } }
