I've already solved this problem in my viewspec proposal. See
http://svn.haxx.se/dev/archive-2006-07/0624.shtml for more details.
Personally, I'd recommend implementing exclusion and inclusion as
options on the viewspec command.
I've included some examples below. These examples are slightly
different from those I originally proposed in the first viewspec
thread, because I've edited them to use explicit operation selection,
as suggested by Max Bowsher.
# Remove a directory from the viewspec
svn viewspec --remove blah
# Add a new directory to the viewspec
svn viewspec --add blah --depth=empty
# Display the current viewspec
svn viewspec
# Edit the viewspec in your editor
svn viewspec --edit
# Export the viewspec to a file
svn viewspec > viewspec.txt
# Update your viewspec to reflect changes you've made on disk
svn viewspec -F viewspec.txt
# Checkout a repository using a viewspec
svn checkout --viewspec viewspec.txt svn://server/trunk
If you want to stick with the 'depth' theme, the output of the
viewspec command could even just include the depth information as it
is displayed on the command line. Here's an example:
$ svn checkout svn://server/repository wc --depth=empty
$ cd wc
$ svn viewspec --add bar --depth=infinite
$ svn viewspec --remove bar/baz
$ svn viewspec --add bar/bah --depth=empty
$ svn viewspec > viewspec.txt
$ cat viewspec.txt
--add . --depth=empty
--add bar --depth=infinite
--remove bar/baz
--add bar/bah --depth=empty
$ svn viewspec --add . --depth=infinite
$ svn viewspec
--add . --depth=infinite
$ svn viewspec -F viewspec.txt
$ svn viewspec
--add . --depth=empty
--add bar --depth=infinite
--remove bar/baz
--add bar/bah --depth=empty
This output isn't as pretty as the Perforce-like syntax I suggested in
the original thread, but it is definitely more explicit. UI
suggestions welcome.
Cheers,
David
