# Essentially a fresh start this time around, but for maximum
# compatibility basic code was taken from, and heavy reference
# made to, the previously unattributed wx-config from cvs.
# All the usual suspects contributed to the dicussion that led
# to this new work and likewise to the ideas and content in the
# original (which was probably influenced by gtk), among them:

wx-config returns information about the wxWidgets libraries available on
your system. It may be used to retrieve the information required to build
applications using these libraries using --cppflags, --cxxflags, --cflags,
and --libs options. And you may query the properties of this configuration
using --query-{host,toolkit,widgetset,chartype,debugtype,version,flavour,
linkage}.
NOTE: Usage of --debug and --query-debugtype are only relevant if you
have any versions prior to 2.9 installed and use the --version option to
select an earlier version.
If multiple builds of wxWidgets are available, you can use the options
--prefix, --host, --toolkit, --unicode, --static, --universal, --version
or --flavour to select from them. The --selected-config option shows the
name of the current configuration and --list shows available alternatives
which match specified criteria. The --utility option returns the correct
version of UTIL to use with the selected build. The --linkdeps option
returns only static libraries for your makefile link rule dependencies.
The LIBS arguments (comma or space separated) may be used to specify the
wxWidgets libraries that you wish to use. The "std" label may be used to
import all libraries that would be used by default if none were specified
explicitly, e.g. wx-config --libs core,base. The "all" label may be used
to import all libraries that have been compiled which are shown in the
list below. The --optional-libs parameter should be followed by a list
of libs that should be linked to, but only if they are available.
Available libraries in this build are:

# Divide the valid arguments into functional groups for later examination,
# then parse all command line arguments completely, deferring action on
# output options until all significant input has been processed and any
# decision about delegation has been taken.
# Note early, that '-' is a complete no-no for use in option names below.
# It totally falls apart as soon as it becomes part of a variable name.
# Use '_' instead, and by the magic of it all just being bits, you'll
# be able to use --my-option or --my_option from the command line at
# your discretion. They are synonymous as user input, but _ALWAYS_ use
# underscores for compound names in the code here, never a dash.

# to match well than those that follow. Options specified by the user will
# always take precedence and are not subject to any partial ordering here.

# From here on, we'll need to be able to figure out a delegation target.
# -----------------------------------------------------------------------
# The rules for delegation are:
#
# 1. If the specification is so general that it matches the default config
# (ie. this one on a first pass), then the default config will be used
# even if other installed libs would also match the spec.
#
# 2. If the default config does not match, find a list of all installed
# libraries that do match.
# a. If that list is empty, the specification is incompatible
# with any installed lib. Warn and abort.
# b. If that list contains exactly one candidate. Delegate to
# that candidate.
# c. If the list contains multiple candidates, pass on to step 3.
#
# 3. Attempt to discriminate among rival candidates by their similarity
# to the default configuration (ie. this one). If we can find a unique
# candidate in this way, delegate to it. If not, present a list of
# options to the user and request that they disambiguate it with one or
# more additional fields.
#
# To refine the specified pattern, we specialise each unbound field
# using the default value from this config file. If that results in
# no matches, we unbind it again and try the next field. If it still
# results in multiple matches we try binding the next field as well
# until a unique or null result again occurs.
#
# A more general way to look at this, is the feature specifiers are all
# modifiers of the wx-config you are calling. If you supply none, the
# default for that build configuration will be used. If you supply one
# or more that the default build cannot satisfy, it will try to find the
# config most like itself with the desired feature(s) enabled.
# The features configured into the first wx-config called will be taken
# as implicitly specified if it is necessary to disambiguate likely
# candidates from the information that was explicitly provided.
# But first, more sugar to keep what follows clear and legible.

# do_find_best_delegate _unbound-options
# The real worker part of find_best_delegate below. Recurses though all
# unbound options binding them one at a time to the default derived from
# this file until a unique match is made or no alternatives remain that
# may be sensibly guessed at. It will preferentially bind the unspecified
# options in the order they are listed in wxconfig_schema. Using this
# partial ordering it should find the first match with the most significant
# similarity to this file that unambiguously meets the user specification.
# If such a match exists it will be output to stdout.
#
# Be careful if you modify this function. If the pruning logic is rendered
# inoperative it will simply recurse over every permutation in the search
# space, which may still appear to work, but add a couple more options (or
# explicitly specify a few less) and you may not live long enough to learn
# the result. WXDEBUG=findprogress is your friend here, it will show you
# how many nodes get searched before a result. If you start seeing
# increases in that number for the same input, check your work.
# Raising the number of discriminating options from 6 to 8 raised the worst
# case time for this to run (without pruning) from 3 to nearly 15 seconds
# and its downhill fast from here if we have to ride that boat.
# Early pruning still gets that down to under half a second (up from about
# .25), so we have some breathing space yet before a different search method
# will be called for, but let's not squander it.
