NAME

ctags-lang-make − Random notes about tagging Make source code with Universal Ctags

SYNOPSIS

ctags ... −−languages=+Make ...

ctags ... −−map−Make=+([Mm]akefile) −−map−Make=+(GNUmakefile) ...
ctags ... −−map−Make=+.mak −−map−Make=+.mk ...

DESCRIPTION

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 /ˆSRC = hello.c$/;" macro language:Make roles:def
all input.mak /ˆall: hello$/;" target language:Make roles:def
base.mak input.mak /ˆ−include base.mak$/;" makefile language:Make roles:optional extras:reference
hello input.mak /ˆhello: hello.o$/;" target language:Make roles:def
hello.o input.mak /ˆhello.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 /ˆCFLAGS = −g −O2$/;" macro language:Make
CPPFLAGS input.mak /ˆCPPFLAGS = −DOUTPUT=stdout$/;" macro language:Make
OUTPUT input.mak /ˆCPPFLAGS = −DOUTPUT=stdout$/;" macro language:CPreProcessor extras:CppDef
SRC input.mak /ˆSRC = hello.c$/;" macro language:Make
all input.mak /ˆall: hello$/;" target language:Make
hello input.mak /ˆhello: hello.o$/;" target language:Make
hello.o input.mak /ˆhello.o: hello.c$/;" target language:Make
