Expand a Makefile string (expand)

expand string

Expands the string string given using remake’s internal variables. The expansion would be the same as if the string were given as a command inside the target.

Example:

remake<0> expand MAKE
(origin default) MAKE := /tmp/remake/src/./make


/tmp/remake/src/Makefile:264: Makefile.in

remake<1> print MAKE  # note the difference with the print
(origin default) MAKE = $(MAKE_COMMAND)

remake<2> expand $(MAKE)   # Note using $( ) doesn't matter here...
/tmp/remake/src/./make     # except in output format - no origin info

/tmp/remake/src/Makefile:264: Makefile.in

remake<2> p COMPILE
Makefile:104 (origin: makefile) COMPILE := $(CC) $(DEFS) $(DEFAULT_INCLUDES)

/tmp/remake/src/Makefile:264: Makefile.in
remake<10> @b{x compile starts: $(CC) $(DEFS) $(DEFAULT_INCLUDES)}
compile starts: gcc -DLOCALEDIR=\"\" -DLIBDIR=\"/usr/local/lib\" -DINCLUDEDIR=\"/usr/local/include\" -DHAVE_CONFIG_H -I. -I..
