From: "nobu (Nobuyoshi Nakada)" Date: 2012-06-13T12:10:56+09:00 Subject: [ruby-core:45618] [ruby-trunk - Bug #6124][Closed] What is the purpose of "fake" gems in Ruby Issue #6124 has been updated by nobu (Nobuyoshi Nakada). Status changed from Open to Closed Sorry for close without the description. The default gem just shows the bundled libraries as also gems, not avoid to install them as-is. The --disable=gem option does not have any effect on standard libraries. @nahi, just keep in your bookmark. ---------------------------------------- Bug #6124: What is the purpose of "fake" gems in Ruby https://bugs.ruby-lang.org/issues/6124#change-27213 Author: vo.x (Vit Ondruch) Status: Closed Priority: Normal Assignee: nahi (Hiroshi Nakamura) Category: Target version: ruby -v: ruby 1.9.3p0 (2011-10-30) [x86_64-linux] As I tried to point out in #6123, the "fake" gems which are distributed with Ruby breaks user's expectations. The following example should fail: $ ruby --disable-gems -e "puts require('bigdecimal')" true However, it is not failing. Could you please enlighten me what is the purpose of fake gem then? Even if you install updated BigDecimal from rubygems.org, the bundled version will won unless you use "gem 'bidgecimal'" somewhere in the code. This makes no sense. Don't take me wrong, I am big fan of gemified stdlib #5481, however this is not the way how it should be done. -- http://bugs.ruby-lang.org/
