v0.4.1 - Fewer False Alarms

🐕 Keela v0.4.1 - "Fewer False Alarms"

The one where Keela stopped barking at shadows.

🔑 Hash Rockets & Rescue Splats

Keela was flagging constants as unused even when they appeared as hash keys:

{ SUCCESS => "ok", FAILURE => "nope" }

Or in rescue splats:

rescue *RECOVERABLE_ERRORS => e

She saw SUCCESS => but the => was confusing her — she thought it was an assignment, not a usage. Fixed. Now hash rockets and rescue splats count. (#63)

🏷️ Symbol References

Rails callbacks, send, validators — they all use symbols:

before_action :authenticate_user
validate :custom_validation
send(:dynamic_method)

Keela was missing these because she only looked for authenticate_user being called, not referenced. Now :method_name counts as usage. (#67)

🌍 I18n Pluralization

You call t('items.count', count: 5) and Rails magically picks items.count.other. But Keela didn't know about this magic — she'd flag items.count.one, items.count.other, and items.count.zero as unused.

Now she understands pluralization siblings. If you use the parent key with count:, the children are safe. (#69)

🔍 I18n Lazy Lookup

In a view at app/views/users/show.html.erb, you write:

<%%= t('.title') %%>

Rails resolves this to users.show.title. Keela now does too. No more false positives on lazy lookups. (#71)

Upgrade

gem install keela
# or
bundle update keela
