remember to compile *before* committing.

2ef880b236 Consolodated some common code into print_matched_line to make 'grep_file' a
little more terse & clean. Also made a few minor formatting changes.

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.

21ddb38fcf Now it's possible to compile Busybox with only one app defined
(unless it's lsmod, to be fixed by the next commit)

a1d187a8a8 Backtick support to infinite (memory limited) levels of nesting is
now implemented...  So now busybox shell can do cool stuff like:

    /home/andersen/CVS/busybox # echo foo `wc README` bar
    foo 71 422 2951 README bar

I love writing cool new features....  Muhahahaha...  (I think this is
leaking a little bit of memory every time it expands a backtick process,
so I still needs to do a bit of cleanup...)

bf181b9338 Extract usage information into a separate file. 2000-07-16 20:57:15 +00:00
Matt Kraai
3bd8bd89ee Don't use strings directly in calls to usage(). This is in preparation
for their extraction to a separate file.

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.

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.

4f7fe77d07 (Something I should have done in the previous checkin...) Also broke out
substitution command execution from do_sed_command() and put it in it's own

expression parsing into it's own subroutine.
