Class Method Details

.dedup_patterns(patterns) ⇒ Array<PatternPresenter>

Deduplicates pattern that have the same arguments_key. Our design for the "paths" helper only allows for one pattern per arguments_key.

If patterns with the same arguments_key are detected, the shortest is taken. If there is a tie, the lexicographically first is taken.
