# Tests for the .unexport directive.
#
# Before 2020-12-13, misspelled directives like ".unexporting" or
# ".unexport-en" had not been detected properly.
#
# See also:
# directive-misspellings.mk
# First, export 3 variables.
UT_A= a
UT_B= b
UT_C= c
.export UT_A UT_B UT_C
# Show the exported variables and their values.
.info ${:!env|sort|grep '^UT_'!}
.info ${.MAKE.EXPORTED}
# XXX: Now try to unexport all of them. The variables are still exported
# but not mentioned in .MAKE.EXPORTED anymore.
# See the ":N" in Var_UnExport for the implementation.
