# TODO:
|
|
#
|
|
# Ideally, this would be able to handle the following gracefully:
|
|
#
|
|
# wrt ls 2016 # all entries for 2016
|
|
# wrt ls 2016/4 # all entries for April 2016
|
|
# wrt ls 2016/4/1 # everything for April 1, 2016
|
|
#
|
|
# ...but I think doing that right requires a much cleaner separation of how
|
|
# entries are _structured_ from how they're _displayed_, probably by moving
|
|
# more operations into WRT::EntryStore.
|
|
#
|
|
# It makes some sense that wrt-ls would just expose the interface of
|
|
# EntryStore in a relatively safe way, including the operations that find
|
|
# things by depth, locate the next/previous entry, etc. All of these could
|
|
# be useful in scripting and publishing pipelines.
