bug#23515: 25.0.93; ruby-mode: regex ending with : fails to terminate

bug#23515: 25.0.93; ruby-mode: regex ending with : fails to terminate

[John Ledbetter]

 

Description: in ruby-mode, ending a regex with a colon is not parsed as
a complete regular expression, which causes the rest of the buffer to be
font-locked as part of the regular expression.

To reproduce:

add the following to a ruby-mode buffer:

# start snippet
x = /http:/
def test
x
end
# end snippet

Note that all lines following the regular expression are font-locked as
part of the regex and do not indent correctly.

Hi Dmitry,

Hi Dmitry,  

In what version is this fixed?  

I see the same behavior in a freshly built emacs:  

GNU Emacs 25.1.50.1 (x86_64-apple-darwin15.4.0, NS appkit-1404.46 Version 10.11.4 (Build 15E65)) of 2016-05-12  


(Sorry for duplicate mail)  

Thanks!
-John
