Rule for Ruby strings

[knut]

Hello,

I try to build a grammar for ruby and I have a problem with a specific string definition..

An example

text = <<helloworld
This is some Text, saying Hello World
A 2nd line is possible (and a 3rd, 4th…)
helloworld

puts text

I made a grammar to mark the string. The strings starts with << followed by a free delimiter (in my example I used 'helloworld'). The delimiter must be repeated later on a single line to finish the string

I tried <<(\w+)$ and wanted to finish it with \1 or ^\1$
BC3 recognize the start of the string, but not the end.
Is there an error, or is the usage of \1 in the to-text not possible?

Attached my rule and a bit ruby-code to test (including some more string definitions in ruby).

I too am interested in Beyond Compare support for Ruby.
I looked at your attached ruby grammar and it looks like a good start for open-sourcing.
Would you like to start a repository on somewhere like github.com?
If not I would be willing to create a repository on github, add the file BCFileFormats.xml,
and start a wiki of general information.
It would also be interesting to create an erb format as a merging of this ruby file and
the existing one for HTML.
