From: shevegen@... Date: 2018-09-15T11:06:17+00:00 Subject: [ruby-core:89029] [Ruby trunk Bug#15123] Enumerable#compact proposal Issue #15123 has been updated by shevegen (Robert A. Heiler). I think if the meaning is consistent (e. g. .compact meaning to eliminate nil values from a given collection) then this seems ok. Perhaps this could be added for the next developer meeting. ---------------------------------------- Bug #15123: Enumerable#compact proposal https://bugs.ruby-lang.org/issues/15123#change-74053 * Author: printercu (Max Melentiev) * Status: Open * Priority: Normal * Assignee: matz (Yukihiro Matsumoto) * Target version: * ruby -v: * Backport: 2.3: UNKNOWN, 2.4: UNKNOWN, 2.5: UNKNOWN ---------------------------------------- Hi! While Enumerable does not provide `#compact` method, it requires changing code in some cases to substitute array with enumerator. For example, to reduce memory usage it's usual to change `large_array.map { to_heavy_object }.chained_methods` to `large_array.lazy...`. However if `chained_methods` contains `compact`, this change will fail. Replacing `compact` with `reject(&:nil?)` fixes it. What do you think about adding `#compact` to Enumerable? -- https://bugs.ruby-lang.org/ Unsubscribe:
