# $NetBSD: opt-jobs-no-action.mk,v 1.9 2021/04/04 09:58:51 rillig Exp $
#
# Tests for the combination of the options -j and -n, which prints the
# commands instead of actually running them.
#
# The format of the output differs from the output of only the -n option,
# without the -j. This is because all this code is implemented twice, once
# in compat.c and once in job.c.
#
# See also:
# opt-jobs.mk
# The corresponding tests without the -n option
# opt-no-action-combined.mk
# The corresponding tests without the -j option
.MAKEFLAGS: -j1 -n
# Change the templates for running the commands in jobs mode, to make it
# easier to see what actually happens.
#
# The shell attributes are handled by Job_ParseShell.
# The shell attributes 'quiet' and 'echo' don't need a trailing newline,
# this is handled by the [0] != '\0' checks in Job_ParseShell.
# The '\#' is handled by ParseGetLine.
# The '\n' is handled by Str_Words in Job_ParseShell.
# The '$$' is handled by Var_Subst in ParseDependencyLine.
