From 8cef5a37ab9d53ee81500b93f44e410c7814a512 Mon Sep 17 00:00:00 2001 From: Nicolas Williams Date: Sun, 15 Feb 2015 17:57:53 -0600 Subject: [PATCH] Add --disable-maintainer-mode; make bison optional Also flex is now optional. The outputs of flex and bison are now committed. By default they get built, but users who want to build from git can now ./configure --disable-maintainer-mode to turn off the dependency on bison and flex. Maintainers must, of course, commit the bison and/or flex outputs when they make changes to parser.y and/or lexer.l, respectively. --- .gitignore | 6 - Makefile.am | 8 + README.md | 15 +- configure.ac | 35 +- lexer.c | 2439 ++++++++++++++++++++++++++++++++++ lexer.h | 362 ++++++ parser.c | 3537 ++++++++++++++++++++++++++++++++++++++++++++++++++ parser.h | 190 +++ setup.sh | 2 +- 9 files changed, 6565 insertions(+), 29 deletions(-) create mode 100644 lexer.c create mode 100644 lexer.h create mode 100644 parser.c create mode 100644 parser.h diff --git a/.gitignore b/.gitignore index f5689661..0f722c29 100644 --- a/.gitignore +++ b/.gitignore @@ -16,12 +16,6 @@ jq.1 # Something delightfully recursive happens otherwise docs/content/2.download/source/* -# Autogenerated -lexer.c -lexer.h -parser.c -parser.h - # Autotools junk .libs .deps diff --git a/Makefile.am b/Makefile.am index 9b9cc5e0..4a14304f 100644 --- a/Makefile.am +++ b/Makefile.am @@ -20,10 +20,18 @@ ACLOCAL_AMFLAGS = -I config/m4 # While there is some autoconf macro support for lex/flex, it doesn't support # header file creation so we'll use good old make +if MAINTAINER_MODE BUILT_SOURCES = lexer.h lexer.c parser.h parser.c version.h lexer.c: lexer.l $(AM_V_LEX) flex -o lexer.c --header-file=lexer.h $< lexer.h: lexer.c +else +BUILT_SOURCES = +.y.c: + $(AM_V_YACC) echo "NOT building parser.c!" +.l.c: + $(AM_V_LEX) echo "NOT building lexer.c!" +endif # 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 diff --git a/README.md b/README.md index c77f3d76..865196a3 100644 --- a/README.md +++ b/README.md @@ -12,14 +12,27 @@ If you want to hack on jq, feel free, but be warned that its internals are not well-documented at the moment.
