[ruby-core:67693] [ruby-trunk - Misc #10757] Vagrant environment for MRI contributors

Issue #10757 has been updated by Nobuyoshi Nakada.


That image is Ubuntu 12.04, just after 2.0 release.
I'm afraid that is too old in these days.

And I'm not sure if these files are nice to be bundled or distributed separatedly.

Anyway, my patch against your v2 patch:

* add `vagrant.md` to `.document` file
* clean up trailing spaces
* use `case...when` instead of repeated `host =~`
* not overwrite existing `configure` file
* use `https:` instead of `http:`
* insert a blank line necessary for code block markdown

Misc #10757: Vagrant environment for MRI contributors
https://bugs.ruby-lang.org/issues/10757#change-51130

* Author: Anthony Crumley

----------------------------------------
This patch includes a Vagrant file that will quickly and easily setup a development environment for MRI contributors.  Following are some benefits of having a vagrant setup for contributors.

* Increase the number of contributors by making it easier to get started.
* Easy setup for someone that wants to contribute to the Ruby test suite but does not really want to become a C developer.  (This is my personal motivation)
* A canonical environment to create and work through issues on.
