# $NetBSD: varname-make_print_var_on_error-jobs.mk,v 1.3 2021/02/04 21:33:14 rillig Exp $
#
# Tests for the special MAKE_PRINT_VAR_ON_ERROR variable, which prints the
# values of selected variables on error.
#
# The variable .ERROR_CMD contains all commands of the target, with variable
# expressions expanded, just as they were printed to the shell command file.
#
# The commands in .ERROR_CMD are space-separated. Since each command usually
# contains spaces as well, this value is only intended as a first hint to what
# happened. For more details, use the debug options -de, -dj, -dl, -dn, -dx.
#
# See also:
# compat-error.mk
# XXX: As of 2021-02-04, PrintOnError calls Var_Subst with SCOPE_GLOBAL, which
# does not expand the node-local variables like .TARGET. This results in the
# double '${.TARGET}' in the output.
# As of 2020-10-23, .ERROR_CMD only works in parallel mode.
.MAKEFLAGS: -j1
MAKE_PRINT_VAR_ON_ERROR= .ERROR_TARGET .ERROR_CMD
all:
@: before '${.TARGET}' '$${.TARGET}' '$$$${.TARGET}'
echo fail ${.TARGET}; false '${.TARGET}' '$${.TARGET}' '$$$${.TARGET}'
@: after '${.TARGET}' '$${.TARGET}' '$$$${.TARGET}'
