1.7: bin/grav yamllinter -a and -f do not follow symlinks

[pamtbaau]

My localhost dev sites use symlinks to link to a Grav installation (to share installation and easy switching 1.6/1.7), and symlinks to their themes and plugins.

Running bin/grav yamllinter -a and bin/grav yamllinter -f do not seem to be following symlinks to themes/plugins.

Environment:

• Windows 10
• Windows Subsystem for Linux
• Ubuntu 20.04.1 LTS
• PHP 7.4.3
• Grav 1.7.0-rc.17 / Grav 1.7.0-rc.18

Repro:

• Create issue in symlinked plugin's blueprints/default.yaml. E.g. @title: Carousel
• Copy files of symlinked plugin folder into regular folder
• Run bin/grav yamllinter -a
  • Regular plugin: throws error
  • Symlinked plugin: no error
• Run bin/grav yamllinter -f user/plugins
  • Regular plugin: throws error
  • Symlinked plugin: no error
• Run bin/grav yamllinter -f user/plugins/<symlink>
  • Symlinked plugin: throws error
