* printf(1): Document that %c and precision for %b/%s use bytes, not chars.jilles2011-05-281-6/+17
| | | | | | | This means these features do not work as expected with multibyte characters. This perhaps less than ideal behaviour matches printf(3) and is specified by POSIX.
* printf: Allow multibyte characters for '<char> form, avoid negative codes.jilles2011-05-282-7/+20
| | | | | | | | | | | | | Examples: LC_ALL=en_US.UTF-8 printf '%d\n' $(printf \'\\303\\244) LC_ALL=en_US.ISO8859-1 printf '%d\n' $(printf \'\\344) Both of these should print 228. Like some other shells, incomplete or invalid multibyte characters yield the value of the first byte without a warning. Note that there is no general way to go back from the character code to the character.

* printf: Do not use sh memory functions in sh builtin.jilles2010-12-291-13/+0
| | | | | | These functions throw exceptions if they fail, possibly causing memory leaks. The normal out-of-memory handling suffices. The INTOFF around almost all of printf prevents memory leaks due to SIGINT.
* sh: Make warnings in the printf builtin non-fatal, like in the program.jilles2010-12-201-17/+13
| | | | | | | | The #define for warnx now behaves much like the libc function (except that it uses sh command name and output). Also, it now uses C99 __VA_ARGS__ so there is no need for three different macros for 0, 1 or 2 parameters.
* Revert r216423 per request from Jilles.delphij2010-12-141-10/+10
| | | | | | | The new behavior prevents us from being able to bail out explicitly on unknown options that we have not implemented. BASH for instance have introduced a '-v' for printf(1) builtin and it seems to be bad to pretend that we supported it and have a script break silently.

* IEEE Std 1003.1-2008, Section 1.4, Utility Description Defaults saysdelphij2010-12-141-10/+10
| | | | | | | | | | | | | | | | | | | | | | | | that when the options section is listed as "None", utility shall recognize "--" as a first argument to be discarded. This implementation is largely based on OpenBSD implementation but we do slightly differently: a) We skip argv[0] as the first step; b) We test whether the next argument is "--" and ignore it. With this change one will get: %printf usage: printf format [arguments ...] %printf -v -v%printf -- -v -v% %printf -- usage: printf format [arguments ...] Which matches the behavior observed on a Debian system but different from the Illumos change.

* printf: Remove support for building as a csh builtin.jilles2010-12-081-8/+2
| | | | | | | | | | The #define BUILTIN was for building as a csh (not tcsh) builtin. Given that csh was replaced by tcsh years ago there is no point in keeping this. The #define SHELL is for building as an sh builtin and is in active use. This commit does not change the /bin/sh and /usr/bin/printf binaries.
* sh: Add printf builtin.jilles2010-11-192-7/+34
| | | | | | | | | | | | | | | | | This was removed in 2001 but I think it is appropriate to add it back: * I do not want to encourage people to write fragile and non-portable echo commands by making printf much slower than echo. * Recent versions of Autoconf use it a lot. * Almost no software still wants to support systems that do not have printf(1) at all. * In many other shells printf is already a builtin. Side effect: printf is now always the builtin version (which behaves identically to /usr/bin/printf) and cannot be overridden via PATH (except via the undocumented %builtin mechanism). Code size increases about 5K on i386. Embedded folks might want to replace /usr/bin/printf with a hard link to /usr/bin/alias.

* printf(1): Clarify that \OOO produces a byte, different %b escape sequences.jilles2010-09-051-4/+10
| | | | | | | | Octal escape sequences are expanded to bytes, not characters, and multiple are required for a multibyte character. The valid escape sequences in %b strings are slightly different from the escape sequences in the format string.
* Build usr.bin/ with WARNS=6 by default.ed2010-01-021-1/+0
| | | | Also add some missing $FreeBSD$ to keep svn happy.
* POSIX says that octal escapes have the format \ddd in the format string,das2008-08-021-1/+2
| | | | | | | | | but \0ddd in a %b argument, with a length restriction of 3 octal digits in either case. This seems silly, but it needs to be right so it's possible to write an octal escape followed by an ordinary digit. Solaris printf(1) and GNU printf(1) also behave this way. Example: "printf '\0752'" now produces "=2" instead of garbage.
