Substitution references (@pxref{Substitution Refs, ,Substitution
References}) are a simpler way to get the effect of the @code{patsubst}
function:
@example
$(@var{var}:@var{pattern}=@var{replacement})
@end example
@noindent
is equivalent to
@example
$(patsubst @var{pattern},@var{replacement},$(@var{var}))
@end example
The second shorthand simplifies one of the most common uses of
@code{patsubst}: replacing the suffix at the end of file names.
@example
$(@var{var}:@var{suffix}=@var{replacement})
@end example
@noindent
is equivalent to
@example
$(patsubst %@var{suffix},%@var{replacement},$(@var{var}))
@end example
@noindent
For example, you might have a list of object files:
@example
objects = foo.o bar.o baz.o
@end example
@noindent
To get the list of corresponding source files, you could simply write:
@example
$(objects:.o=.c)
@end example
@noindent
instead of using the general form:
@example
$(patsubst %.o,%.c,$(objects))
@end example
function.
@item $(strip @var{string})
