Support setting location of rubocop config about haml-lint HOT 5 CLOSED

The way haml-lint does this is by creating a temporary file in the same directory as the original .haml file being linted. This results in rubocop automatically using the correct configuration.

Is there any possibility you could do the same? I would rather not include a hack for a specific linter if it can be avoided.

Thank you for the response.

My package is very simple and I feel a bit like I'm standing with one leg each on the shoulders of two giants (haml-lint and atom's linter), delicately pointing them both in the right direction. :)

The behavior of linter to write files to /tmp is quite deeply ingrained and not configurable. While I can't speak for the intent of the authors, I suspect it may be intentional. Node's tempfile utilities do not have the magic of ruby's TempFile class where the tempfile gets cleaned up with garbage collection pretty much no matter what. By writing to /tmp, no garbage is left behind within the source code in the event of the unexpected, e.g. if the editor crashes.

I'm much more familiar with ruby than node, so this is the natural direction for me to turn first. It seems like the fact that Rubocop::CLI#run accepts overriding ARGV is a boon for HamlLint::CLI to accept a separate option for the location of .rubocop.yml and pass it through in a straight-forward manner.

I know it feels like a bit of a kludge to have two options for config files and this is definitely an edge case, but there are two separate linters at play here. Would you be willing to entertain a pull request that does what I have described?

One last question: is it possible for you to set an environment variable before executing haml-lint?

Rather than expose a flag on the command-line (and having to maintain code that passes that all the way through to the linter), I'd be more comfortable with an environment variable (something like HAML_LINT_RUBOCOP_CONF) that the RuboCop linter can recognize and pass on as a flag to Rubocop::CLI#run.

This would allow the code to only exist in the RuboCop linter, maintaining isolation from the rest of the system.

Setting an environment variable is definitely doable, I have submitted a pull request to linter to support it.

Closing as this seems to have lost steam. Feel free to reopen when this is ready to pursue again.
