echo fooba | ./busybox sed -n 's/foo//;s/bar/found/p'
I really need to start adding these tests to the testsuite.
keep the substituted and altered flags seperate
If a label isnt specified, jump to end of script, not the last command
in the script.
Print an error and exit if you try and jump to a non-existant label
Works for the following testcase
# cat strings
a
b
c
d
e
f
g
# cat strings | ./busybox sed -n '/d/b;p'
a
b
c
e
f
g
Fixed a memory leak in add_cmd/add_cmd_str by moving the allocation
of sed_cmd down to where it's actually first needed.
In get_address, if index_of_next_unescaped_regexp_delim ever failed, we
wouldn't notice because the return value was added to idx, which was
already guaranteed to be > 0. (This is buried in the changes made when
I redid get_address to be based on pointer arithmetic, because all the tests
were gratuitously dereferencing with a constant zero, which wasn't obvious.)
Comment in parse_regex_delim was wrong: 's' and 'y' both call it.
The reason "sed_cmd->num_backrefs = 0;" isn't needed is that sed_cmd was
allocated with cmalloc, which zeroes memory.
Different handling of space after \ in i...
Different handling of pattern "s/a/b s/c/d"
Cool, resursive reads don't cause a crash. :)
Fixed "sed -f blah filename - < filename" since GNU sed was handling
both - and filenames on the same line. (You can even list - more than
once, although it's immediate EOF...)

Hello all,
This patch adds more "Help" text to the config system. Almost
all applets now have a help entry. Also, I cleaned up the spacing of
the existing text so that things are consistent. This patch is against
this morning's CVS.

modified Kbuild system I put into uClibc. With this, there should be no more
need to modify Rules.mak since I've moved all the interesting options into the
config system. I think I've got everything updated, but you never know, I may
have made some mistakes, so watch closely.

the busybox development tree. This eliminates the use of recursive make, and
once again allows us to run 'make' in a subdirectory with the expected result.
And things are now much faster too. Greatly improved IMHO...
-Erik
make busybox be more uClinux friendly. I also adjusted Config.h for
uClinux so it will automagically disable apps the arn't going to
work without fork() and such.

1) ping cleanup (compile fix from this patch already applied).
2) traceroute call not spare ntohl() now (and reduce size);
3) Fix for functions not declared static in insmod, ash, vi and mount.
4) a more simple API cmdedit :))
5) adds "stopped jobs" warning to ash on Ctrl-D and fixes "ignoreeof" option
6) reduce exporting library function index->strchr (traceroute), bzero->memset (syslogd)
- Fixed bug where you couldn't use two addresses for a 'c' cmd
- Moved the do_sed_cmd function into process_file to simplify some things
- Reduced a buncha lines of code in the process
- All of the ESC sequences are now in variables. This should make
re-targeting for other terminals easier.
- The initial screen draw does not force out every single column.
Should be faster.
- The place_cursor() routine trys to be smarter about moving the
cursor. This is optional based on BB_FEATURE_VI_OPTIMIZE_CURSOR.
- The 't' and 'f' intra-line positioning commands were added.
They can now be used as targets in 'c' and 'd' commands, i.e.,
dfx - delete from dot to next 'x'
dtx - delete from dot to the char before next 'x'
- show_status_line() uses a static int checksum to remember what
is currently displayed on the screen and not re-draw the status
line unless it has changed.
- Some of the code in refresh() was moved out to format_line().
refresh() trys to send out the smallest segment containing
the changed chars rather than the whole line.
- Added "flash" to the :set command to specify if error indication
should be by flashing the screen or ringing the bell.
- Changed the rawmode() routine so that it turns off the
NL -> CR NL translation. On output of a NL, the OS will not add
a CR.
- If vi was started as "view", with global read-only mode,
and another file is opened, the file is opened read-only
rather than read+write.
busybox.h which slowed compiles. I left only what was needed and then fixed up
all the apps to include their own header files. I also fixed naming for pwd.h
and grp.h functions. Tested to compile and run with libc5, glibc, and uClibc.
-Erik
a few other ugly places (do_subst_command got a much-needed overhaul). Also
took out BB_FEATURE_SED_PATTERN_SPACE from Config.h[.Hurd] as the 'p' is now a
standard feature (adds almost no bloat).
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.
(\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.
- 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.
- 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.
