whalelint's Issues

Support Arg variable resolution.

Arg variable resolution is not necessarily straightforward, because:

  • Not all fields are exported in BuildKit's representation, so raw lines are not editable at the moment, which is not a showstopper, but needs a bit of a thinking.
  • Back and forth mapping is needed for proper location handling.
  • Args might be mixed with "inline" defined env vars in RUN commands.

whalelint background process 100% CPU

IntelliJ freezes with the whalelint background process consuming 100% CPU.
Are there some debug options for understanding what's going wrong?

apt-get update complains about not being passed -y

Thanks for the great work Tamas!
apt-get update && apt-get install --no-install-recommends -y ...
Complains about -y not being passed to update, also the install has still a warning to add --no-install-recommends, although being fixed.
