I see. Thank you for finding a gem which is widely used and has incompatibility about this. I hope we will try this in later release. ---------------------------------------- Bug #11842: r53123 breaks some gems which use erb https://bugs.ruby-lang.org/issues/11842#change-55694 * Author: Kaneko Yuichiro * Status: Closed * Priority: Normal * Assignee: * ruby -v: ruby 2.3.0dev (trunk 53153) [x86_64-darwin14] * Backport: 2.0.0: UNKNOWN, 2.1: UNKNOWN, 2.2: UNKNOWN ---------------------------------------- r53123 breaks some gems which use erb. Thor gem for example. They set an instance variable `"@output_buffer"` to 4th argument (`eoutvar`) of `ERB.new` ([here](https://github.com/erikhuda/thor/blob/f0c2166534e122636f5ce04d61885736ef605617/lib/thor/actions/file_manipulation.rb#L116)). And change this instance variable from outside erb ([here](https://github.com/erikhuda/thor/blob/f0c2166534e122636f5ce04d61885736ef605617/lib/thor/actions/file_manipulation.rb#L308)). [Example code of erb](https://github.com/ruby/ruby/blob/ec7a964dca57821d2d7a36f168c2355a46a76ca2/lib/erb.rb#L751) shows this usage of `eoutvar`. I think we should revert r53123 and add a test case for this usage. ``` Failures: 1) Thor::Actions#template allows using block helpers in the template Failure/Error: concat(result.strip + " world!")
