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

  43    wx-config returns  information about  the wxWidgets libraries available
  44    on your system.  It may be used to retrieve the information you require
  45    to build applications using these libraries.
  46
  47     If alternative builds of wxWidgets exist on the system, you can  use the
  48   options: --prefix, --host, --toolkit,  --unicode, --debug, --universal and
  49   --version, to select from them.  Use the --list option  to show all builds
  50   which  match any  specified criteria.   The unicode, universal,  and debug
  51   options take an optional yes or no argument, while host and version accept
  52   posix extended regex.  eg. wx-config --unicode=n --debug --host=?.* --list
  53   will show all ansi-debug libraries installed, including cross libraries.
  54
  55     Optional LIB arguments (comma or space separated) may be used to specify
  56   the wxWidgets libraries that  you wish  to use.  The magic "std" label may
  57   be used to import all libraries that would be used by default if none were
  58   specified explicitly.  eg. wx-config --libs core,base.

 453 # From here, we now need to figure out a delegation target.
 454 # --------------------------------------------------------------
 455
 456 # The rules for delegation are:
 457 #
 458 # 1. If the specification is so general that it matches the default config
 459 #    (ie. this one on a first pass), then the default config will be used
 460 #    even if other installed libs would also match the spec.
 461 #
 462 # 2. If the default config does not match, find a list of all installed
 463 #    libraries that do match.
 464 #       a. If that list is empty, the specification is incompatible
 465 #          with any installed lib.  Warn and abort.
 466 #       b. If that list contains exactly one candidate.  Delegate to
 467 #          that candidate.
 468 #       c. If the list contains multiple candidates, pass on to step 3.
 469 #
 470 # 3. Attempt to discriminate among rival candidates by their similarity
 471 #    to the default configuration (ie. this one).  If we can find a unique
 472 #    candidate in this way, delegate to it.  If not, present a list of
 473 #    options to the user and request that they disambiguate it with one or
 474 #    more additional fields.
 475 #
 476 #    To refine the specified pattern, we specialise each unbound field
 477 #    using the default value from this config file.  If that results in
 478 #    no matches, we unbind it again and try the next field.  If it still
 479 #    results in multiple matches we try binding the next field as well
 480 #    until a unique or null result again occurs.
 481 #
 482 # A more general way to look at this, is the feature specifiers are all
 483 # modifiers of the wx-config you are calling.  If you supply none, the
 484 # default for that build configuration will be used.  If you supply one
 485 # or more that the default build cannot satisfy, it will try to find the
 486 # config most like itself with the desired feature(s) enabled.
 487 # The features configured into the first wx-config called will be taken
 488 # as implicitly specified if it is necessary to disambiguate likely
 489 # candidates from the information that was explicitly provided.
 490
 491
 492 # But first, more sugar to keep what follows clear and legible.

 507 # do_find_best_delegate _unbound-options
 508 # The real worker part of find_best_delegate below.  Recurses though all
 509 # unbound options binding them one at a time to the default derived from
 510 # this file until a unique match is made or no alternatives remain that
 511 # may be sensibly guessed at.  It will preferentially bind the unspecified
 512 # options in the order they are listed in wxconfig_schema.  Using this
 513 # partial ordering it should find the first match with the most significant
 514 # similarity to this file that unambiguously meets the user specification.
 515 # If such a match exists it will be output to stdout.
 516 #
 517 # Be careful if you modify this function.  If the pruning logic is rendered
 518 # inoperative it will simply recurse over every permutation in the search
 519 # space, which may still appear to work, but add a couple more options (or
 520 # explicitly specify a few less) and you may not live long enough to learn
 521 # the result.  WXDEBUG=findprogress is your friend here, it will show you
 522 # how many nodes get searched before a result.  If you start seeing
 523 # increases in that number for the same input, check your work.
 524 # Raising the number of discriminating options from 6 to 8 raised the worst
 525 # case time for this to run (without pruning) from 3 to nearly 15 seconds
 526 # and its downhill fast from here if we have to ride that boat.
 527 # Early pruning still gets that down to under half a second (up from about
 528 # .25), so we have some breathing space yet before a different search method
 529 # will be called for, but lets not squander it.
