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" | $EGREP "$1" 2> /dev/null; } + +# user_mask_fits _config +# Returns true if the string _config satisfies the user specified mask. +user_mask_fits() { echo "$1" | $EGREP "$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 \"\\\${$1-unset}\"`" != "xunset" ]; } + +# not _cmd _args... +# true iff _cmd is false +not() { if "$@"; then false; else true; fi; } + +# do_find_best_delegate _unbound-options +# The real worker part of find_best_delegate below.
