2004-03-15Remove trailing whitespace. Update copyright to include 2004.Eric Andersen
2004-02-18Add -i option to sed, to edit files in-place.Rob Landley
2004-02-04Rob Landley writes:Eric Andersen
While building glibc with busybox as part of the development environment, I found a bug in glibc's regexec can throw sed into an endless loop. This fixes it. Should I put an #ifdef around it or something? (Note, this patch also contains the "this is not gnu sed 4.0" hack I posted earlier, which is also needed to build glibc...)
2004-01-04Thinko in s//options. (Whitespace skipping in the wrong place.)Rob Landley
2003-12-23Patch from Matt Kraai:Eric Andersen
sed is broken: busybox sed -n '/^a/,/^a/p' >output <<EOF a b a b EOF cmp -s output - <<EOF a b a EOF The attached patch fixes it.

2003-10-09Comaptability with gcc-2.95Glenn L McGrath
2003-10-04Patch from Rob Landley;Glenn L McGrath
Moving on to building diffutils, busybox sed needs this patch to get past the first problem. (Passing it a multi-line command line argument with -e works, but if you don't use -e it doesn't break up the multiple lines...)
2003-10-01Patch from Rob Landley to fix backrefsGlenn L McGrath
2003-10-01Patch by Rob Landley, fix "newline after edit command"Glenn L McGrath
2003-10-01Patch by Rob Landley, work in progress update, fixes lots of bugs,Glenn L McGrath
introduces a few others (but they are being worked on)
2003-09-24Fix some typo's, remove some extra free statementsGlenn L McGrath
2003-09-16Configuration option to define wether to follows GNU sed's behaviour Glenn L McGrath
or the posix standard. Put the cleanup code back the way it was.
2003-09-16Fix a bug that creapt in recently with substitution subprinting, and addGlenn L McGrath
a test for it.
2003-09-15Fix a simple mistake with pattern space, and add a test for itGlenn L McGrath
2003-09-15Fix some memory allocation problemsGlenn L McGrath
----------------------------------------------------------------------
2003-09-15Add a test for the 'P' command and fix current implementation so itGlenn L McGrath
doesnt permanently modify the pattern space.
2003-09-15A test and fix for the sed 'n' commandGlenn L McGrath
2003-09-15Fix for the sed-append-next-line testGlenn L McGrath

2003-09-14Memory cleanups and fix for `echo "foo" | sed 's/foo/bar/;H;q'`Glenn L McGrath
2003-09-14Cleanup memory usageGlenn L McGrath
2003-09-14The previous fix for 's/a/1/;s/b/2/;t one;p;:one;p' broke the case ofGlenn L McGrath
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
2003-09-14Preserve substitution flag value within the current line.Glenn L McGrath
Fixed the following testcase # cat strings |./busybox sed -n -f test3.sed 1 1 2 c c # cat strings a b c
2003-09-14Fix branching commands.Glenn L McGrath
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
2003-09-14Patch from Rob Landley Glenn L McGrath
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...)
2003-09-14Stupid typoGlenn L McGrath
2003-09-14Fix some memory allocation problemsGlenn L McGrath
2003-09-13Fix the following testcase by disabling global substitution if the regexGlenn L McGrath
is anchored to the start of line, there can be only one subst. echo "aah" | sed 's/^a/b/g'
2003-09-13Fix the following testcase by storing the state of the adress match withGlenn L McGrath
the command. # cat strings a b c d e f g # ./busybox sed '1,2d;4,$d' <strings c # ./busybox sed '4,$d;1,2d' <strings # sed '4,$d;1,2d' <strings c # sed '1,2d;4,$d' <strings c
2003-08-30Fix the substitution print subcommand, it should only print if itsGlenn L McGrath
