From 8876fb2f59a0b515b3121d5894933eef88ce566a Mon Sep 17 00:00:00 2001 From: Eric Andersen Date: Fri, 20 Jun 2003 09:01:58 +0000 Subject: last_patch89 from vodz: Manuel, I rewrite bb_getopt_ulflags() function for more universal usage. My version support now: - options with arguments (optional arg as GNU extension also) - complementaly and/or incomplementaly and/or incongruously and/or list options - long_opt (all applets may have long option, add supporting is trivial) This realisation full compatibile from your version. Code size grow 480 bytes, but only coreutils/* over compensate this size after using new function. Last patch reduced over 800 bytes and not full applied to all. "mkdir" and "mv" applets have long_opt now for demonstrate trivial addition support long_opt with usage new bb_getopt_ulflags(). Complementaly and/or incomplementaly and/or incongruously and/or list options logic is not trivial, but new "cut" and "grep" applets using this logic for examples with full demostrating. New "grep" applet reduced over 300 bytes. Mark, Also. I removed bug from "grep" applet. $ echo a b | busybox grep -e a b a b a b But right is printing one only. --w vodz --- coreutils/cut.c | 68 +++++++++++++++++----------------------- coreutils/date.c | 65 +++++++++++++++++--------------------- coreutils/dd.c | 4 +-- coreutils/df.c | 32 ++++++------------- coreutils/du.c | 93 ++++++++++++++++++++++++++++--------------------------- coreutils/env.c | 17 +++------- coreutils/mkdir.c | 26 ++++++++++------ coreutils/mv.c | 36 +++++++++++---------- coreutils/rm.c | 22 +++++-------- coreutils/stty.c | 71 +++++++++++++++++++++--------------------- coreutils/test.c | 6 ++-- 11 files changed, 199 insertions(+), 241 deletions(-) (limited to 'coreutils') diff --git a/coreutils/cut.c b/coreutils/cut.c index c24cf6611..8ae762fb3 100644 --- a/coreutils/cut.c +++ b/coreutils/cut.c @@ -22,20 +22,22 @@ #include #include -#include /* getopt */ +#include +#include #include #include #include "busybox.h" -/* globals from other files */ -extern int optind;
