Looking at the old code, it became clear that the desired functionality with the t-flag could not be added unless the underlying data-structures were reworked. Thus the only way to be successful was to rewrite the whole thing. od(1) allows giving arbitrarily many type-specs per call, both via -t x1o2... and -t x1 -t o2 and intermixed. This fortunately is easy to parse. Now, to be flexible, it should not only support types of integral length. Erroring out like this is inacceptable: $ echo -n "shrek"| od -t u3 od: invalid type string ‘u3’; this system doesn't provide a 3-byte integral type Thus, this new od(1) just collects the bytes until shortly before printing, when the numbers are written into a long long with the proper offset. The bytes per line are just the lcm of all given type-lengths and >= 16. They are equal to 16 for all types that are possible to print using the old od(1)'s. Endianness is of course also supported, needs some testing though, especially on Big Endian systems.

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.
