A file with the MRB file extension is a MacMolecule file.
you can use notepad to open such files.

see below link for the same.

List of recommended software associated to the .mrb file extension
Recommended software programs are sorted by OS platform (Windows, Mac OS X etc.) and possible program actions
that can be done with the file: like open mrb file, edit mrb file, convert mrb file, view mrb file, play mrb file etc. (if exist software for corresponding action in File-Extensions.org's database).
http://www.file-extensions.org/mrb-file-extension

So you can try that also.

from where you get this file an email attachment or somewhere else?

Don't go looking for "file viewing" software or you are likely to just end up installing crappy "optimising" or "fix-all" utilities that purport to fix registry errors associated with particular file extensions.  If the file doesn't open on your computer and you are wondering what will open it, then it is improbable that the file type has ever been associated with any program on your computer, and therefore programs that pretent they can "fix" file associations aren't going to do you any good.

I have never used the FileViewPro program suggested in the first comment, but it's plain to see how they capture passing trade.
Compare the instances of "MRB" on the page that is generated from the link given earlier:
http://www.fileviewpro.com/en/file-extension-mrb
with the one generated dynamically by just changing the "mrb" at the end of the URL to "LOL":
http://www.fileviewpro.com/en/file-extension-LOL
Kind of generic, eh?  It says that the software "Opens over 150+ file formats".  Well, so does Windows Notepad, but that doesn't mean that it will be in a more readable format than Notepad or a Hex Editor.

Unless you are digging out old Floppy, CD, or other archives, or are just randomly poking around files, then you must have even a small idea of what type of content these files are likely to contain, ie. digital image, logs, database, configuration, etc.  If you received the file as an email attachment, and you don't know what the file is, then ask the sender if you know that person or, if you don't know that person, don't try and open it.

The first thing you should look for in any file is a file header acronym.  For example, if you open a JPG image file in a text editor or hex editor, right at the start you will see "JFIF" which is the header applied to files of this type.  I ZIP file will show "PK" up at the top as a reference to the original "PKZIP" if it has been saved as a standard Zip file, and near the end of all the gobbledegook code you usually see a list of the file names in the archive suffixed by "PK".  In a text editor a Windows "executable" program (EXE, DLL, etc) will have "MZ" up near the top and "PE" a few lines down, you will see "!This program cannot be run in DOS mode", and near the end you will see the double-spaced letters (unicode) giving version information.

If you can see a header acronym, then you can sometimes look that up.  One free command line utility that attempts to identify a file using a database containing many thousands of file signatures is TrID by Marco Pontello.  I don't see .MRB in his current definition list, so on that basis it's hardly worth trying that program.  If Marco's database of 5,132 file types doesn't contain .MRB, then I sincerely doubt whether the FileViewPro will be able to show anything other than the text-based content.  Feel free to try though.

Is there any possibility that you may be able to attach this file renamed with a .TXT extension for us to look at, or is there a fear that it may contain sensitive data?

Looks like you're right about Ruby:

http://blog.mruby.sh/201207020720.html - Bytecode (.mrb)

Unfortunately that's where my knowledge begins to thin out.  I have only dabbled with a few programming languages and have never learned anything about Ruby.  Sorry.
