0.3.10 Syntax error with ruby 2.1, requires 2.3

[Skulli]

I still have an older app with an old ruby version

gem install mimemagic -v '0.3.10'

fails with

/mimemagic-0.3.10/ext/mimemagic/Rakefile:46: syntax error, unexpected <<, expecting ')'
    f.print(<<~SOURCE
    ^mimemagic-0.3.10/ext/mimemagic/Rakefile:51: syntax error, unexpected ')', expecting keyword_end

The <<~ only allowed with ruby 2.3+

Possible to make that code compatible with ruby 2.1? <<- should be enough here.

Thanks @Skulli , I have fixed the syntax as suggested by you and it's working for me for ruby 2.2.1

Thanks, looks fine for me. Awaiting the merge :)

It would be great if this merge could gain some traction, this issue is holding up dev on a number of legacy sites we manage and i would imagine many others in the rails ecosystem.

+1 this would help us out as well @DataDog as our Ruby gem also supports older rubies and this is affecting our test suite.

+1 any update on timing for the merge?

I am on ruby 2.2.4 and throwing the same syntax error , So updated my rake file and run bundle install , but bundle install updates the rakefile to the previous syntax and throws syntax error

There's a fork (https://github.com/powarvinayak/mimemagic) containing the fix since this is taking so long to merge

+1. It breaks my gem's test cases. (with mimemagic-0.4.3)
