From: oliverp@... Date: 2018-12-14T17:35:56+00:00 Subject: [ruby-core:90529] [Ruby trunk Feature#11076] Enumerable method count_by Issue #11076 has been updated by odlp (Oliver Peate). For me the definition of tally does seem to fit the use case, so +1 to `tally(_by)`. One other suggestion - how about [census](https://www.merriam-webster.com/dictionary/census) (as in `census_by(&:downcase)`)? It's more widely used than tally (although I think tally is the better choice): [https://books.google.com/ngrams/graph?content=tally%2Ccensus%2Ccount&case_insensitive=on&year_start=1900&year_end=2008](https://books.google.com/ngrams/graph?content=tally%2Ccensus%2Ccount&case_insensitive=on&year_start=1900&year_end=2008) ---------------------------------------- Feature #11076: Enumerable method count_by https://bugs.ruby-lang.org/issues/11076#change-75683 * Author: haraldb (Harald B��ttiger) * Status: Open * Priority: Normal * Assignee: * Target version: ---------------------------------------- I very often use `Hash[array.group_by{|x|x}.map{|x,y|[x,y.size]}]`. Would be nice with to have a method called `count_by`: ~~~ruby array = ['aa', 'aA', 'bb', 'cc'] p array.count_by(&:downcase) #=> {'aa'=>2,'bb'=>1,'cc'=>1} ~~~ -- https://bugs.ruby-lang.org/ Unsubscribe:
