Regular expression in ruby to match the text between first occurrence and last occurrence of a character

Can anyone help me to form a regular expression in ruby that would match the text between first occurrence and last occurrence of a character.

For example, for the character -:

ruby-on-rails should get result --> on

abc-def-ghi-jkl should get result --> def-ghi

mnop-qrst-uvw-xyza-bc-defg-hij-123 should get result --> qrst-uvw-xyza-bc-defg-hij

Thoughts appreciated!

'ruby-on-rails'.scan(/-(.*)-/).first.first

This very simple regex will do (because the * operator is greedy by default):

/-(.*)-/

In ruby:

'ruby-on-rails'[/-(.*)-/, 1]
# => "on" 
'abc-def-ghi-jkl'[/-(.*)-/, 1]
# => "def-ghi"
'mnop-qrst-uvw-xyza-bc-defg-hij-123'[/-(.*)-/, 1]
# => "qrst-uvw-xyza-bc-defg-hij"

This will do it:

result = subject.scan(/-(.*)-/)
