# Redefine the %{global:greeting} parameter of %{global:echo} before using it.
# The necessary expansion order was established in the test suite config
# (%{global:echo} before %{global:greeting}), and redefining the parameter
# doesn't change that expansion order.  That order would be reversed if
# %{global:greeting} were handled as a new substitution, preventing full
# expansion.
#
# REDEFINE: %{global:greeting}=Hello
# RUN: %{global:echo}
# CHECK: GLOBAL: Hello World

# We can redefine the test suite config's substitutions multiple times.  Again,
# the expansion order remains the same (%{global:echo} before %{global:greeting}
# before %{global:what}) but would be reversed if these were handled as new
# substitutions, preventing full expansion.
#
# REDEFINE: %{global:greeting}=Goodbye %{global:what}
# REDEFINE: %{global:what}=Sleep
# RUN: %{global:echo}
# CHECK: GLOBAL: Goodbye Sleep Sleep

# A new local substitution is prepended to the substitution list so that it can
# depend on all substitutions that were defined previously, including those from
# the test suite config.
#
# DEFINE: %{local:greeting}=Hey %{global:what}
# DEFINE: %{local:echo}=echo "LOCAL: %{local:greeting} %{global:what}"
# RUN: %{local:echo}
# CHECK: LOCAL: Hey Sleep Sleep

# As for substitutions from the test suite config, redefining local
# substitutions should not change the expansion order.  Again, the expansion
# order would be reversed if these were instead handled as new substitutions,
# preventing full expansion.
#
# REDEFINE: %{local:greeting}=So Long %{global:what}
# REDEFINE: %{global:what}=World
# RUN: %{local:echo}
# CHECK: LOCAL: So Long World World

# CHECK: Passed: 1
