Best practices: living with .svn?
It would be a BIG help if people on this list would publish their
collection of "living with .svn directories" suggestions and scripts,
hopefully to be migrated to "the book" someday. I find that
directory incredibly intrusive since it seriously interferes with
recursive finds and greps.
#1 on the wish list: what is the svn-friendly way to use grep -r foo
src to find all the foos in my working src directory, without
interference from hits in svn's administrative area (.svn). Hopefully
a global setting somewhere so I don't have to type special commands
each time. There are hopeful prospects in the man pages but I've not
yet hit on a working combination.
I'll start the ball rolling with the latest gotcha that bit me
(thanks to Ben for the solution)
When using eclipse within svn-managed directories, the root
directories of your package hierarchy will show up as grey empty
packages. DO NOT USE ECLIPSE TO DELETE THEM. They are not empty as
far as svn is concerned for they contain svn's administrative (.svn)
directories. If you do delete them, the only solution is to move the
package (src) directory aside, run svn update to create a a new (but
stale) copy, and manually update it with changed files from the copy
you moved aside.

I meant a command like "wcgrep regex -- -dirname" should be
transformed to a pipe beginning with "find ./-dirname" because
"find -- -dirname" does not work.

That's what "--" is for.
grep "regex" -- -filename.txt
find -args -print0 | xargs -r0 grep 'regex' --

In GNU grep 2.5.1, --exclude does not apply to names of
directories. (See grep-2.5.1/lib/savedir.c.) Thus, that command
will still search all .svn/README.txt files, among others.
A pipe like this would avoid that problem:
find . -name .svn -prune -or -print0 | xargs -r0 grep -H regex
However, this is more difficult to wrap with a grep-like syntax:
the directory (or file) names would have to be separated from
grep options, and names like -foo would have to be changed to
./-foo.
I think the cleanest solution would be to patch grep. It could
take a new "--exclude-dir=.svn" option, or extend the existing
"--exclude=.svn" to affect directories too, or require
"--exclude=.svn/".

Thanks! That explained why my previous shot didn't work. But I don't
want to retrain my fingers to type rg instead of grep.
Setting $GREP_OPTIONS in ~/.bashrc like this did the trick
export GREP_OPTIONS="--exclude="\*/.svn/\*"

I've made use of
alias rg='grep --exclude=\*.svn\* -r'
And then was able to type
rg foo src

There is a wcgrep script in contrib.
