sbase - suckless unix tools
===========================

sbase  is a  collection of  unix  tools that  are inherently  portable
across UNIX and UNIX-like systems.

The following tools are implemented ('*' == finished, '#' == UTF-8 support,
'=' == implicit UTF-8 support):

The  complement of  sbase  is  ubase[1] which  is  Linux-specific  and
provides all  the non-portable tools.   Together they are  intended to
form a base system similar to busybox but much smaller and suckless.

Building
--------

To  build sbase,  simply  type  make.  You  may  have  to fiddle  with
config.mk depending on your system.

You  can  also  build  sbase-box,  which  generates  a  single  binary
containing  all  the  required  tools.    You  can  then  symlink  the
individual tools to sbase-box.

Ideally you will  want to statically link sbase.  If  you are on Linux
we recommend using musl-libc[2].

Portability
-----------

sbase has been  compiled on a variety of  different operating systems,
including Linux, *BSD, OSX, Haiku, Solaris, SCO OpenServer and others.

Various combinations of operating  systems and architectures have also
been built.

You can build sbase with gcc, clang, tcc, nwcc and pcc.

Add column to mark UTF-8 support One major milestone is to have the sbase-tools supporting UTF-8. Tools like cut(1) with the -n flag don't make sense otherwise. And while the gnu coreutils cut(1) blatantly ignores such an important aspect, we will not tolerate this madness and mark it as a TODO in the main README. Since most tools inherently support UTF-8 anyway, this just concerns tools which mangle with text or search in it in special ways. 2015-01-18 13:36:13 -05:00			`The following tools are implemented ('*' == finished, '#' == UTF-8 support,`

Add printf(1) This is a particularly interesting program. I managed to implement everything according to POSIX except how octal escapes are specified in the standard, which is yet another format compared to the one demanded for tr(1). This not only confuses people, it also adds unnecessary cruft for no real gain. So in order to be able to use unescape() easily and for consistency, I used our initial format \o[oo] instead of \0[ooo]. Marked as optional is UTF-8 support for %c in the POSIX specification. Given how well-developed libutf has become, doing this here was more or less trivial, putting us yet again ahead of the competition. 2015-02-15 08:46:58 -05:00			`#* printf yes none`

Add UTF-8-support to strings(1), add t-flag and refactor code Previously, the string-length was limited to BUFSIZ, which is an obvious deficiency. Now the buffer only needs to be as long as the user specifies the minimal string length. I added UTF-8-support, because that's how POSIX wants it and there are cases where you need this. It doesn't add ELF-barf compared to the previous implementation. The t-flag is also pretty important for POSIX-compliance, so I added it. The only trouble previously was the a-flag, but given that POSIX leaves undefined what the a-flag actually does, we set it as default and don't care about parsing ELF-headers, which has already turned out to be a security issue in GNU coreutils[0].
