'Rubocop: Exclude files from a list given on command line

I run rubocop from my pre-commit hook script:

bin/bundle exec rubocop ${FILES}

with ${FILES} being the list of files staged for commit. This does not, however, honour the contents of the AllCops/Exclude section in rubocop.yml.

Since there are files that will always generate offences (e.g. schema.rb), is there a way to make the config Exclude section precede the command line parameters?

Solution 1:^[1]

I edited my pre-commit script to generate a temporary Rubocop config, that inherits from the main one. The temporary config only contains the AllCopsInclude section, which seems to work fine with AllCops/Exclude in the main config. No need to tamper with inherit_mode.

TEMP_CONFIG=/tmp/rubocop-`date +%s`.yml
RUBOCOP_CONFIG=`realpath .rubocop.yml`
cat << EOF > $TEMP_CONFIG
inherit_from: $RUBOCOP_CONFIG
AllCops:
  Include:
EOF
for file in "${FILES[@]}"; do
    echo "    - $file" >> $TEMP_CONFIG
done
bin/bundle exec rubocop -a -c $TEMP_CONFIG
rm $TEMP_CONFIG

Not that I know, but I agree there should be (or it should be easier).

A few issues are already opened about that. Maybe splitting that setting in two (e.g. with a AllCops/AlwaysExclude or a AllCops/ExcludeByDefault) is needed.

There is a inherit_mode option but I'm not 100% sure how it works or if it could help

rubocop has command-line option --force-exclusion which excludes files specified in the .rubocop.yml Exclude section. This was added on pull request 922.
