linux like behavior in windows shell - running ruby without "ruby" appended to the command?

Question

This is probably a really silly question bu tI can't seem to find an answer since I'm apparently failing on keywords.

You know how you can run commands from the commandline in linux if you put a line on the top of your .rb file so you don't have to type ruby myfile.rb all the time and can just do ./myfile.rb ? Is it possible to have the same thing on a windows environment? I use git bash as my shell most of the time and have a lot of cygwin binaries installed. It's just that the general method is to put that line on top and then chmod the file, which isn't really an option.

Answer 1

May be you need to define regular windows file association?

Answer 2

Yes, you can:

assoc .rb=RubyScript
ftype RubyScript=ruby "%1" %*

After that you can simply call your ruby script like an executable program.

If you also want to be able to drop the .rb file extension, then you need to include .rb in the PATHEXT environment variable.

Answer 3

If you want a graphical tool to assist with this on Win 7, you might want to check out: http://defaultprogramseditor.com/

With this tool, you can easily edit the context menu items for .rb files (or any other files)

for the "open" command to be:

ruby "%1" %*

and you can create an "edit" command, such as:

c:\ruby\scite\scite.exe "%1"

As noted above, if you do not specify %* after "%1", your script will not see any of the command line arguments. And don't forget to add .RB to the PATHEXT environment variable.
