Railsters:

Here’s the command to get the revision log between a given revision and  
the  
state-of-the-art:

svn log [http://my](http://my)…repository/trunk --revision 42:head

Under our usual mix of Capistrano and SVN, how would one write a  
Capistrano  
task to…

- collect the last deployment’s revision number
- sample that log
- e-mail the log to a list of e-mail addresses?

I attempted this script, and immediately got mired in the kind of absurd  
details that other systems take for granted, but which Rails has taught  
me  
I’m doing something wrong. So I throw the question open…

(And, naturally, Googling for “send e-mail” is hopeless!😉

Write a “before\_deploy” task which…

> - collect the last deployment’s revision number

Looks at #{deploy\_to}/revisions.log and takes the last file which looks  
like this:

2007-08-27 15:19:12 web 6604 20070827221715

The fourth record is the SVN revision.

> - sample that log

Apply the above to your svn command via “system” or IO.popen and capture  
the output.

> - e-mail the log to a list of e-mail addresses?

Send it using net/smtp.
