From: "zverok (Victor Shepelev)" Date: 2021-12-02T19:41:47+00:00 Subject: [ruby-core:106412] [Ruby master Feature#18369] users.detect(:name, "Dorian") as shorthand for users.detect { |user| user.name == "Dorian" } Issue #18369 has been updated by zverok (Victor Shepelev). > it would be nice to have syntax that allows to shorten one-line matchers for predicates where they would be commonly used TBH, since pattern matching inception I hope for some way of putting patterns into values���to store them in constants, and, in that case, simple `grep` will do (if that value would respond to `#===` which it should!): ```ruby MY_PATTERN = _pm_(first_name: /^J/, age: 18..) # ...and then if value in MY_PATTERN ... # ...and, consequently, people.grep(_pm_(first_name: /^J/, age: 18..)) ``` (I am marking the dreamed-of PM constructor as ugly `_pm_` here to underline it is not a ready proposal, but "something should be here") ---------------------------------------- Feature #18369: users.detect(:name, "Dorian") as shorthand for users.detect { |user| user.name == "Dorian" } https://bugs.ruby-lang.org/issues/18369#change-95052 * Author: dorianmariefr (Dorian Mari��) * Status: Open * Priority: Normal ---------------------------------------- Hi, I was thinking I often do things like `collection.detect { |item| item.attribute == value }` and a shorthand like `collection.detect(:attribute, value)` would be quite useful What do you think? And I know there is `collection.detect { _1.attribute == value }` but I try not to use `_1` and this syntax would be shorter and simpler Could also apply to other methods like `all?` (`collection.all?(:attribute, value)`), and basically any Enumerable method https://rubydoc.info/stdlib/core/Enumerable -- https://bugs.ruby-lang.org/ Unsubscribe:
