As discussed in #5695, I think we're reaching a point where removing Autotools is preferable to fixing it. 1.14.x continues to use Autotools, so platforms whose Meson version is too old can stay on that branch until it becomes unsupported. We have a very conservative Meson dependency (Ubuntu 20.04). Signed-off-by: Simon McVittie <smcv@collabora.com>

# 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}
