# ----------------
# - INSTRUCTIONS -
# ----------------
# The DMPRoadmap codebase tries to follow the latest Ruby/Rails style guidelines as defined
# by the community via the Rubocop gem.
#
# Before submitting a PR, please run `bin/rubocop` from the project root.
#     Note that you can specify individual files or folders e.g.: `bin/rubocop app/mailers`
#     Note you can let Rubocop auto-correct many issues with the `-a` flag
#
# New versions of Rubocop typically include new Cops (Cops are inidivual Rubocop rules).
# If you see a message like the following when you run `bin/rubocop`:
#
#    "The following cops were added to RuboCop, but are not configured. Please set Enabled
#     to either `true` or `false` in your `.rubocop.yml` file."
#
# You should copy and paste the specified Cops into this file. You can review what the
# Cop will do by Googling the name of the rule e.g.: "rubocop Layout/SpaceBeforeBrackets"
#
# After you review the rule, you can either Enable it or Disable it in this file. The
# Rubocop documentation for the Cop may also give you additional options that can be
# configured.
#
# Try to place any new Cops under their relevant section and in alphabetical order

# Default is 100 lines. Most of our controllers, models, etc. violate this
# Cop, so setting it to 300 since we do not have time to refactor everything
Metrics/ClassLength:
  Max: 300
# briley Oct. 4th 2021
# Default is 10 lines which feels very restrictive but would also require us to do
# too much refactoring at this point.
Metrics/MethodLength:
  Max: 20

# mnicholson Oct. 6th 2021
# Default lenght for block is 25 lines, which it would be very restrictive for
# the Rspec views methods. So I'll just exclude some files.
