From: "sawa (Tsuyoshi Sawada)" Date: 2022-10-15T16:57:11+00:00 Subject: [ruby-core:110315] [Ruby master Feature#17290] Syntax sugar for boolean keyword argument Issue #17290 has been updated by sawa (Tsuyoshi Sawada). I think Marc-Andre and Brandon's idea can be limited to be relevant only for receiving the parameters (in a definition), and it will still make sense. My proposal is is about the parameters (in a method call). I think they can be kept distinct. I rarely see people using `gets(chomp: true)`, and I think it is because it is shorter to write `gets.chomp`. It is a pity that such a useful feature was introduced, but no one uses it because the old school way is more convenient. ---------------------------------------- Feature #17290: Syntax sugar for boolean keyword argument https://bugs.ruby-lang.org/issues/17290#change-99605 * Author: sawa (Tsuyoshi Sawada) * Status: Open * Priority: Normal ---------------------------------------- We frequently use keyword arguments just to pass `true` value out of the truthy/falsy options given. And in many such cases, the falsy option is set as the default, and only the truthy value is ever passed explicitly. I propose to have a syntax sugar to omit the value of a keyword argument. When omitted, it should be interpreted with value `true`. ```ruby gets(chomp:) CSV.parse(" foo var ", strip:) ``` should be equivalent to ```ruby gets(chomp: true) CSV.parse(" foo var ", strip: true) ``` Additionally, we may also extend this to pragmas. ```ruby # frozen_string_literal: ``` to be equivalent to: ```ruby # frozen_string_literal: true ``` -- https://bugs.ruby-lang.org/ Unsubscribe:
