| | | | | | | | | | | | | POSIX requires that non-existent or null arguments be treated as if a zero argument were supplied. Add regression tests to catch this case as well. PR: bin/174521 Approved by: cperciva (mentor, implicit) Notes: svn path=/stable/9/; revision=246277

* printf: Allow multibyte characters for '<char> form, avoid negative codes.Jilles Tjoelker2011-05-281-4/+18
| | | | | | | | | | | | | | | | 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. Notes: svn path=/head/; revision=222418
* printf: Note that this is used both as a normal program and a shell builtin.Jilles Tjoelker2011-03-011-0/+4

* printf: Do not use sh memory functions in sh builtin.Jilles Tjoelker2010-12-291-13/+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. Notes: svn path=/head/; revision=216809
* sh: Make warnings in the printf builtin non-fatal, like in the program.Jilles Tjoelker2010-12-201-17/+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. Notes: svn path=/head/; revision=216606
* Revert r216423 per request from Jilles.Xin LI2010-12-141-10/+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. Notes: svn path=/head/; revision=216447

* IEEE Std 1003.1-2008, Section 1.4, Utility Description Defaults saysXin LI2010-12-141-10/+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.Jilles Tjoelker2010-12-081-8/+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. Notes: svn path=/head/; revision=216310
* sh: Add printf builtin.Jilles Tjoelker2010-11-191-6/+24
| | | | | | | | | | | | | | | | | | | | 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. Notes: svn path=/head/; revision=215520
* POSIX says that octal escapes have the format \ddd in the format string,David Schultz2008-08-021-1/+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. Notes: svn path=/head/; revision=181153
