### C source files to be built

JQ_INCS = jq_parser.h builtin.h bytecode.h compile.h execute.h		\
  forkable_stack.h frame_layout.h jv.h jv_alloc.h jv_aux.h jv_dtoa.h	\
  jv_parse.h jv_unicode.h locfile.h opcode.h opcode_list.h parser.y	\

  jv_parse.c jv_print.c jv_dtoa.c jv_unicode.c jv_aux.c jv_alloc.c	\
  lexer.c jq_test.c ${JQ_INCS}


### C build options

AM_CFLAGS = -Wextra -Wall -Wno-missing-field-initializers	\
  -Wno-unused-parameter -Wno-unused-function


### Generating the lexer and parser

# While there is some autoconf macro support for lex/flex, it doesn't support
# header file creation so we'll use good old make
BUILT_SOURCES = lexer.h lexer.c
lexer.c: lexer.l
	flex -o lexer.c --header-file=lexer.h lexer.l
lexer.h: lexer.c

# Tell YACC (bison) autoconf macros that you want a header file created.
# If the --warnings=all fails, you probably have an old version of bison
# OSX ships an old bison, so update with homebrew or macports
AM_YFLAGS = --warnings=all -d



### Building the jq binary

main.c: config.h

bin_PROGRAMS = jq
jq_SOURCES = ${JQ_SRC} main.c


### Tests

# this is what gets "make check" to work
TESTS = tests/all.test
TEST_LOG_COMPILER = tests/run



### Packaging

# setup is only used by distribution developers, not package developers.
# Still, as a matter of allowing patching, its not a bad idea to distribute 
# the developer setup script in the tarball.
EXTRA_DIST = setup.sh config.h.in ChangeLog lexer.l lexer.h	\
  gen_utf8_tables.py jq.spec testdata

# README.md is expected in Github projects, good stuff in it, so we'll 
# distribute it and install it with the package in the doc directory.
docdir = ${datadir}/doc/${PACKAGE}
dist_doc_DATA = README.md COPYING AUTHORS README
