Overview
This parser extracts macro and target definitions. It also extracts included files as references.
Examples
"input.mak"
-include base.mak SRC = hello.c all: hello hello: hello.o hello.o: hello.c $(CC) -c $(CFLAGS) $(CPPFLAGS) $<
"output.tags" with "--options=NONE --extras=+r --fields=+KlrE -o - input.mak"
SRC input.mak /^SRC = hello.c$/;" macro language:Make roles:def all input.mak /^all: hello$/;" target language:Make roles:def base.mak input.mak /^-include base.mak$/;" makefile language:Make roles:optional extras:reference hello input.mak /^hello: hello.o$/;" target language:Make roles:def hello.o input.mak /^hello.o: hello.c$/;" target language:Make roles:def
Extracting CPP macro defintions defined with -dfoo
With -D option in a C compiler like gcc, a programmer can define a macro outside C source files. The options appears on a Makefile frequently. For an example:
CPPFLAGS = -DDEBUG
The Make parser has heuristics [DINMAKE] for extracting the macros defined with the option. With enabling CppDef extra, you can turn on the heuristics.
Examples
"input.mak"
-include base.mak CFLAGS = -g -O2 CPPFLAGS = -DOUTPUT=stdout SRC = hello.c all: hello hello: hello.o hello.o: hello.c $(CC) -c $(CFLAGS) $(CPPFLAGS) $<
"output.tags" with "--options=NONE --extras-Make=+{CppDef} --fields=+KlE -o - input.mak"
CFLAGS input.mak /^CFLAGS = -g -O2$/;" macro language:Make CPPFLAGS input.mak /^CPPFLAGS = -DOUTPUT=stdout$/;" macro language:Make OUTPUT input.mak /^CPPFLAGS = -DOUTPUT=stdout$/;" macro language:CPreProcessor extras:CppDef SRC input.mak /^SRC = hello.c$/;" macro language:Make all input.mak /^all: hello$/;" target language:Make hello input.mak /^hello: hello.o$/;" target language:Make hello.o input.mak /^hello.o: hello.c$/;" target language:Make
