# ======================================================================
# Here follows some extensive mental masturbation about how to
# make the manifest file and search algorithm even more complex.
# I think this is all gratuitous, really.
# Hmm, something extra: want to apply an exclude pattern over a whole
# subtree without necessarily having to explicitly include files from it,
# ie. it should apply after gathering files by other means (simple
# include pattern)
# . !*~ !*.bak !#*#
# and we also want to prune at certain directories:
# . !RCS !CVS
# which again should apply globally.
#
# possible solution:
# - exclude pattern in a directory applies to all files found under that
# directory
# - subdirectories that match an exclude pattern will be pruned
# - hmmm, to be consistent, subdirectories that match an include
# pattern should be recursively included
# - and this should apply to "simple" patterns too
#
# thus:
#
# examples/
#
# means get everything in examples/ and all subdirs;
#
# examples/ !*~ !#*# !*.py[co]
#
# means get everything under examples/ except files matching those three globs;
#
# ./ !RCS !CVS
#
# means get everything under current dir, but prune RCS/CVS directories;
#
# ./ !*~ !#*# !*.py[co] !RCS !CVS
# ! build/
# ! experimental/
#
# means get everything under the distribution directory except the usual
# excludes at all levels; exclude "build" and "experimental" under the
# distribution dir only.
#
# Do the former examples still work?
#
# distutils/ *.py
# ! distutils/bleeding_edge.py
#
# means all .py files recursively found under distutils, except for the one
# explicitly named.
#
# distutils/ *.py !bleeding_edge.py
#
# means the same, except bleeding_edge.py will be excluded wherever it's
# found -- thus this can exclude up to one file per directory under
# distutils.
#
# distutils/*.py
# ! distutils/bleeding_edge.py
#
# gets exactly distutils/*.py, minus the one explicitly mentioned exclude, and
#
# distutils/*.py
# distutils/ !bleeding_edge.py
#
# coincidentally does the same, but only because there can only be one file
# that matches the exclude pattern. Oh, we'd still like
#
# distutils *.py !bleeding*.py
# distutils/bleeding_ledge.py
#
# to include distutils/bleeding_ledge.py -- i.e. it should override the
# earlier exclude pattern by virtue of appearing later in the manifest. Does
# this conflict with the above requirements, ie. that "!RCS" and "!*~" should
# apply everywhere? Hmm, I think it doesn't have to, as long as we're smart
# about it. Consequence:
#
# . !RCS !CVS
# distutils *
#
# will go ahead and include RCS and CVS files under distutils, but
#
# distutils *
# . !RCS !CVS
#
# will do the right thing. Hmmm. I think that's OK, and an inevitable
# consequence of the ability to override exclusions.
# OK, new crack at the search algorithm.
#
# for pattern in manifest:
# if dir-pattern: # ie. first word is a directory (incl. "."!)
# dir = first word on line
# patterns = rest of line
# if patterns:
# for dpattern in patterns:
# if exclude-pattern:
# remove from files anything matching dpattern (including pruning
# subtrees rooted at directories that match dpattern)
# else:
# files.append (recursive_glob (dir, dpattern))
# else:
# files.append (recursive_glob (dir, '*')
#
# elif include-pattern: # it's a "simple include pattern"
# files.append (glob (pattern))
#
# else: # it's a "simple exclude pattern"
# remove from files anything matching pattern
# The two removal algorithms might be a bit tricky:
#
# "remove simple exclude pattern":
# for f in files:
# if f matches pattern:
# delete it
#
# "remove recursive exclude pattern":
# for f in files:
#
# t = tail (f)
# while t:
# if t matches pattern:
# delete current file
# continue
# t = tail (t)
#
# Well, that was an interesting mental exercise. I'm not completely
# convinced it will work, nor am I convinced this level of complexity
# is necessary. If you want to exclude RCS or CVS directories, just
# don't bloody include them!
