Is there any good software that will allow me to search through my SVN respository for code snippets? I found 'FishEye' but the cost is 1,200 and well outside my budget.
If you're searching only for the filename, use:
svn list -R file:///subversion/repository | grep filename
Windows:
svn list -R file:///subversion/repository | findstr filename
Otherwise checkout and do filesystem search:
egrep -r _code_ .
