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.
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:
'#' -> UTF-8 support, '=' -> Implicit UTF-8 support, '*' -> Finished,
'|' -> Audited, 'o' -> POSIX 2013 compliant, 'x' -> Non-POSIX,
'()' -> Petty flag

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 or run: make sbase-box-install
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.
