#!/bin/bash
# This script expands test-matrix expressions into indiviual featuressets
#
# The basic element is a feature, which is just a name:
# "a" == enable feature a
#
# A featureset is a comma separated list of features:
# "a,b,c" == enable feature a, b and c
#
# A test-matrix is a list of featuresets to test and are specified by
# separating featuresets by '+':
# "a,b+a,c+e" == featuresets "a,b", "a,c" and "e"
#
# At any point in the expression where a feature is expected you can
# instead specify an entire test-matrix by enclosing a sub-expression
# in brackets. The result is the combinatorial combination of the
# sub-test-matrix with the current featureset.
#
# For example:
#
# "a,{b+c}" == "a,b+a,c"
# or:
# "a,b,{c,d+e,f}" == "a,b,c,d+a,b,e,f"
#
# This can happen multiple times in an optionset which will fully expand all
# instances:
# "a,{b+c},{d+e}" == "a,{b+c},d+a,{b+c},e" == "a,b,d+a,c,d+a,{b+c},e" == "a,b,d+a,c,d+a,b,e+a,c,e"
#
#
# The common way to use this is to either list all the options to instance the test for each case:
# foo+bar+gazonk
# Or to create all combination of features:
# {foo+nofoo},{bar+nobar}
