one-line log format for svn

svn log | perl -l40pe 's/^-+/\n/'
the output of svn log is annoying to grep, since it spreads the useful info over multiple lines. This compacts the output down to one line so eg you can grep for a comment and see the rev, date & committer straight away. Updated: MUCH shorter, easier to remember. Now it just replaces newlines with spaces, except on '---' lines.
Sample Output
r14341 | bob | 2011-10-14 15:57:17 +0100 (Fri, 14 Oct 2011) | 1 line jack leave that alone
r14316 | jack | 2011-10-13 21:54:52 +0100 (Thu, 13 Oct 2011) | 1 line thing still broken
r14315 | jack | 2011-10-13 18:03:41 +0100 (Thu, 13 Oct 2011) | 1 line fixed the thing
r14307 | bob | 2011-10-13 15:49:29 +0100 (Thu, 13 Oct 2011) | 1 line made a thing

  • dirrrty: use -p to chomp automatically, substitute all newlines away and then replace the "---" by a newline ? bingo! s/// => s/// is just a cooler way to write s///, s/// which is just the small brother of s///; s/// (comma is an operator!) have fun!

    svn log | perl -pe 's/\n//g => s/^-.*/\n/g'
