RE: [CONTRIB] `sfind', a wrapper around `find' that ignores .svn directories

A simpler (though much dumber) version, if you're willing to install a
couple of CPAN directories:

--START--use strict;
use warnings;
use File::Find::Rule;
use File::Find::Rule::VCS;
print "$_\n" for
File::Find::Rule->ignore_svn->file->name($ARGV[0])->in('.');
---END---

For what I usually end up using find for in working copies, it does the
trick. And due to the simplicity of File::Find::Rule's interface, it would
be pretty simple to extend if needed.

Thanks

Subject: [CONTRIB] `sfind', a wrapper around `find' that ignores .svn
directories

I use this (surprisingly complicated :-( ) script constantly, and have told
Emacs to use it instead of `find'. I suspect it'd be useful for other *nix
svn users too.

I have a sneaking suspicion that it doesn't do the right thing in every
case, but I haven't nailed it down. In any case, it's mighty useful.

    #!/usr/bin/perl -w

    use strict;
    use Data::Dumper;

    # A wrapper around GNU find. It ignores Subversion cache directories,
    # but otherwise acts the same.

    # Subversion includes a similar tool in
    # .../contrib/client-side/wcgrep; it runs a recursive grep, ignoring
    # Subversion cache directories.

    my @files;
    my @expression_bits;

    # Consume find's arguments, one by one. As soon as we see an argument
    # that looks like an expression, then it and every remaining argument
    # are expressions. Until then, all the arguments are files.

    push @files , shift @ARGV while
(@ARGV && $ARGV[0] !~ m{^[-(!]});

    push @expression_bits, shift @ARGV while
(@ARGV);

    # We need to add `-print' if they didn't specify actions. Actions
    # begin with hyphens, so they're easy to recognize ... except they
    # might be buried inside parentheses.

    {
      my @tmp = @expression_bits;

      # Get rid of any trailing right-parens.
      pop @tmp while (@tmp && $tmp[-1] eq ")");

      push @expression_bits, qw(-print)
        unless (@tmp
                && ($tmp[-1] =~ m(^-) # most action arguments begin with a
hyphen.

                    || $tmp[-1] eq ";" # the last argument to `-exec' is
                                       # always a semicolon.
                   ));
    }

    unshift @expression_bits, qw(( -type d -name .svn -prune ) -o);

    # Let's get GNU find if possible
    my $prog = "find";

    if ($^O =~ m(freebsd)i) {
      my $gf = "/usr/local/bin/gfind";
      $prog = $gf if (-x $gf);
    }

    exec ($prog, @files, @expression_bits);
