9b04f1841e Fix the substitution print subcommand, it should only print if its 
own substitution matched, not previous ones.
e.g
echo fooba | sed -n 's/foo//;s/bar/found/p'
shouldnt print anything

ed3ef50c23 Fix header file usage -- there were many unnecessary header files included in 
busybox.h which slowed compiles.  I left only what was needed and then fixed up

2dc192fd99 Re-worked the support for s///p, fixed a backref limit buglet, and cleaned up

standard feature (adds almost no bloat).

1f45b268cb As per a discussion on the mailing list between Matt and Pavel. I have removed 
the -V (version) flag from busybox sed. It is unnecessary because sed is not a
standalone and should therefore be independently reporting a version number.
Moreover, it is extra code that we just don't need.

97562bd9d7 - Added support for backreferences in substitution expressions up to nine 
(\1, \2...\9). This touched a lot of places in this file and I added a new
   function 'print_subst_w_backrefs' in order to keep 'do_subst_command' a
   little more tidy.

	* I tested this good 'n hard, but will always appreciate more testing from
	  other, willing folks.

 - Noticed that the index_of_next_unescaped_slash was subtly wrong so I
   changed both the functionality and behavior (it used to skip over the first
   char in the string you passed it, assuming it was a leading '/'--this
   assumption is no longer made) this necessitated changing the lines that
   call this function just slightly.

bf181b9338 Extract usage information into a separate file. 2000-07-16 20:57:15 +00:00
Mark Whitley
464c5de00d Fixed a couple of buglets: 
- add_cmd_str: segv's were being generated if there was a '# comment' line
   (and probably other kinds of lines, too) that was not followed by a
   semi-colon or whitespace
 - parse_edit_cmd: was returning a wrong number (too low) for the index; it
   was not accounting for backslashes eaten, for the fact that we start at the
   3rd index in the string, or for the fact that we add an extra newline.
 - parse_cmd_str: was returning a wrong number (again, too low) for the index
   in the case of single-letter commands (p,d). There was some
   over-compensation for this in the 'return' stmt at the end which also
   needed some help.
 - load_cmd_file: was not eating trailing newlines off the line read from the
   command file. This had the deleterious effect of printing an extra newlines
   after text displayed from edit (i,a,c) commands.
 2000-07-14 23:24:00 +00:00
Mark Whitley
70705d7c96 - Added support for semicolon delimited command lines. (woo-hoo!) 
- Obsoleted the trim_str function (#if 0'ed out -- maybedelete later) in
   favor of strrspn.
 - Obsoleted the strrspn function (#if 0'ed out as well) as soon as I
   discovered that it wasn't needed either.
 - Fixed a subtle bug in parse_subst_cmd where it would choke with an error if
   there was any trailing space after the s/match/replace/ expression.

34623db618 It dawned on me that I would need to grow a char buffer one extra char bigger 
to accomodate a trailing '\n'ewline that I append to it later one. This is
only necessary for the case of one inserted, appended, or changed line, but
it's still necessary.

06f3529ada Minor code reorg: Changed the interface to index_of_next_unescaped_slash to an 
interface that seems a little more sensible to me. Also broke out s///
expression parsing into it's own subroutine.

c41e8c840f Changed bb_regcomp to xregcomp and #if 0'ed out destroy_cmd_strs in sed.c 
(maybe I'll remove it later).

858c1adf2b Applied patch from Matt Kraai to call destroy_cmd_strs in atexit(), rather 
than peppering it throughout the code.

df5f6ba115 Applied patch from Matt Kraai which does the following: 
- adds case-insensitive matching in sed s/// epxressions
 - consolodates common regcomp code in grep & sed into bb_regcomp and put in
   utility.c
 - cleans up a bunch of cruft

6315ce603b Brand, new sed that uses libc regex routines. 
There is some common code used by both sed & grep that should be put into
utility.c as per Mat Kraai's suggestions/patch on the mailing list.
Specifically, a common regex_compile() and a regex_subst() function need to be
made.

b610615be9 Updates to a number of apps to remove warnings/compile errors under libc5. 
Tested under both libc5 and libc6 and all seems well with these fixes.

7ab9c7ee52 Lots of updates. Finished implementing BB_FEATURE_TRIVIAL_HELP 
which lets you compile out most of the "--help" output, saving
up to 17k.

Renamed mnc to nc.

would go into an infinite loop.

7dc160721e Bunches of fixes. Typos, bugs, etc. 
Added 'gunzip -t'.  inittab support _almost_ works (but it isn't
ready for prime time useage yet).

1266a13e1f * sed now supports addresses (numeric or regexp, with negation) and 
has an append command, thanks to Marco Pantaleoni <panta@prosa.it>
* Fixed dmesg.  It wasn't parsing its options (-n or -s) properly.
* Some cosmetic fixes to ls output formatting to make it behave more
    like GNU ls.
