FRIGN eb9bda8787 Support NUL-containing lines in sort(1)
For sort(1) we need memmem(), which I imported from OpenBSD.
Inside sort(1), the changes involved working with the explicit lengths
given by getlines() earlier and rewriting some of the functions.

Now we can handle NUL-characters in the input just fine.

FRIGN e4810f1cdb Support NUL-containing lines in cols(1)
This required an architectural change in getlines() by also storing
the line length.

FRIGN 2d7d2261a0 Really force 1 entry per line with -1 in ls(1)
if a filename contains a \n, it would not be limited to one line.
We use the qflag to replace the control characters with '?'s.

FRIGN 97ce9ea586 Fix -s in tr(1)
Forgot that in case there is a second argument given with -s you
probably want to have your characters substituted.
I changed it so that shortly before "deploying" we check if the
"to be written"-Rune is equal to the last Rune, and proceed as

Quentin Rameau d04402b6ea cat: fix u flag
Our libutil concat() always uses a buffer for input wich is obviously
not compatible with unbuffered io. Here is a local uconcat() which
naively copies input to stdout char by char.

Quentin Rameau 3da450e203 printf: replace strtonum with strtol functions in conversions
Use strtol and strtoul respectively for d, i and o, u, x, X conversions.
This way we can convert other bases than 10, which strtonum doesn't
Also don't exit on conversion error but display a warning, set a return
error code, and continue.

FRIGN b83916ca27 Add symbol to mark NUL handling in each tool (and where it is missing)
The assumption of NUL-terminated strings is actually quite a good one in
most cases. You don't have to worry about paths, because they may not
contain NUL.
Same applies to arguments passed to you. Unless you have to unescape,
there is no way for you to receive a NUL.

There are two important exceptions though, and it's important that we
address them, or else we get unexpected behaviour:

	1) All tools using unescape() have to be strict about delimlen.
	   Else they end up for instance unescaping
	   which in C's string-vision is an empty string.

	2) All tools doing line wrenching and putting them out
	   again as lines again.
	   puts() will cut each line containing NULs off at the first

FRIGN a88906b423 Rever the strmem() addition and add a TODO element
strmem() was not very well thought out. The thing is the following:
If the string contains a zero character, we want to match it, and not
stop right there in place.

The "real" solution is to use memmem() where needed and replace all
functions that assume zero-terminated-strings from standard input, which
could lead to early string-breakoffs.
This requires a strict tracking of string lengths.
2016-02-26 09:54:46 +00:00
FRIGN 3396088666 Implement strmem() and use it in join(1)
We want our delimiters to also contain 0 characters and have them
handled gracefully.
To accomplish this, I wrote a function strmem(), which looks for a
certain, arbitrarily long memory subset in a given string.
memmem() is a GNU extension and forces you to call strlen every time.

FRIGN 79e8e330cb Fix wc(1) output for large files
Previously, we used the System V output format:
	"%7d%7d%7d %s\n"
The problem here is, that if any number has more than six digits, the
result looks like one big number, as we don't mandate spaces.

POSIX says the output format should rather be
	"%d %d %d %s\n"
but in this case we wouldn't get consistent results.

To serve both camps, I changed it to the following:
	"%6d %6d %6d %s\n"
This won't change the output for normal values, but also
prevent the output of large files to be ambiguous.

FRIGN 41a600e1b8 Allow \0ooo octal escapes
Yeah well, the old topic. POSIX allows \0123 and \123 octals in
different tools, in printf, depending on %b or other things.
We'll just keep it simple and just allow 4 digits. the 0 does not make
a difference anyway.
