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. # -------------------------------------------------------------- # find_eligible_delegates _mask # Outputs all the config files installed which match the # (extended regex) _mask passed as an argument. find_eligible_delegates() { echo "$installed_configs" | grep -E "$1" 2> /dev/null; } # user_mask_fits _config # Returns true if the string _config satisfies the user specified mask. user_mask_fits() { echo "$1" | grep -E "$configmask" > /dev/null 2>&1; } # count_fields _word # Returns the number of IFS split fields in _word count_fields() { return $#; } # count_delegates _mask # Return the number of eligible config files that match _mask count_delegates() { count_fields $(find_eligible_delegates $1); } # is_set _variablename # Returns true if $_variablename is initialised. is_set() { [ "x$(eval echo \"\${$1-unset}\")" != "xunset" ]; } # do_find_best_delegate _unbound-options # The real worker part of find_best_delegate below. Recurses though all # unbound options binding them one at a time to the default derived from # this file until a unique match is made or no alternatives remain that # may be sensibly guessed at. It will preferentially bind the unspecified # options in the order they are listed in wxconfig_schema. Using this # partial ordering it should find the first match with the most significant # similarity to this file that unambiguously meets the user specification. # If such a match exists it will be output to stdout. # # Be careful if you modify this function. If the pruning logic is rendered # inoperative it will simply recurse over every permutation in the search # space, which may still appear to work, but add a couple more options (or # explicitly specify a few less) and you may not live long enough to learn # the result. WXDEBUG=findprogress is your friend here, it will show you # how many nodes get searched before a result. If you start seeing # increases in that number for the same input, check your work. # Raising the number of discriminating options from 6 to 8 raised the worst # case time for this to run (without pruning) from 3 to nearly 15 seconds # and its downhill fast from here if we have to ride that boat. # Early pruning still gets that down to under half a second (up from about # .25), so we have some breathing space yet before a different search method # will be called for, but lets not squander it. do_find_best_delegate() { ( if [ "x$WXDEBUG" = "xverbose" ]; then _fbd_indent="${_fbd_indent}.
