Hello,
To the best of my
knowledge, currently there's no way to determine the name of the makefile
currently being read. This information is useful to me, and I'd like to
implement a 'thisfile' function that returns it. The change would be
minimal; basically I'd need to add func_thisfile() and ouput the
reading_file->filenm string. Also, a small change to lookup_function()
is required so that we don't always assume that a function name has a whitespace
or '\0' after it.
Would such a change
be acceptable for inclusion in the next release? Of course I will
implement, thoroughly test, and document it.
In case you're
wondering, I use the name of the makefile stub to generate a variable name
prefix to avoid name collisions anywhere within a mountain of
makefiles. This can be used to implement a very simple
non-recursive process. For example (just off the top of my
head):
%.o :
%.c
$(CC) $(if $($(call
get_prefix,$(@D))_CFLAGS),$($(call
get_prefix,$(@D))_CFLAGS),$(CFLAGS))
In other words, here
if an included makefile stub has a
variable $(call get_prefix $(dir $(thisfile)))_CFLAGS set, it will be used for
files in the same directory; otherwise the default CFLAGS will be
used. There's probably other circumstances where $(thisfile) would come in
handy, also.
Thanks,
Mark
