I have just learned that zsh(1) calls this concept being "full". http://zsh.sourceforge.net/Doc/Release/Expansion.html#Glob-Qualifiers ---------------------------------------- Feature #12075: some container#nonempty? https://bugs.ruby-lang.org/issues/12075#change-57121 * Author: Yui NARUSE * Status: Assigned * Priority: Normal * Assignee: Yukihiro Matsumoto ---------------------------------------- I sometimes write following code. ``` ary = some_metho_returns_nil_or_empty_container() # nil or "" or [] or {} if ary && !ary.empty? # some code end ``` But the condition `ary && !ary.empty?` is too long and complex. Though Ruby 2.3 introduces `&.`, but this can���t be written as `ary&.empty?`. One idea is add `nonempty?` write as `ary&.nonempty?`. akr: `nonempty?` is not good name because human is not good at handling This discussion matches following core classes: * String * Array * Hash -- https://bugs.ruby-lang.org/ Unsubscribe:
