1) Remove the function prototypes. No need for them, as the functions are ordered. 2) Add fieldseplen, so the length of the field-separator is not calculated nearly each time skipcolumn() is called. 3) rename next_col to skip_to_next_col so the purpose is clear, also reorder the conditional accordingly. 4) Put parentheses around certain ternary expressions. 5) BUGFIX: Don't just exit() in check(), but make it return something, so we can cleanly fshut() everything. 6) OFF-POSIX: Posix for no apparent reason does not allow more than one file when the -c or -C flags are given. This can be problematic when you want to check multiple files. With the change 5), rewriting check() to return a value, I went off-posix after discussing this with Dimitris to just allow arbitrary numbers of files. Obviously, this does not break scripts and is convenient for everybody who wants to quickly check a big amount of files. As soon as 1 file is "unsorted", the return value is 1, as expected. For convenience reasons, check()'s warning now includes the filename. 7) BUGFIX: Set ret to 2 instead of 1 when the fshut(fp, *argv) fails. 8) BUGFIX: Don't forget to fshut stderr at the end. This would improperly return 1 in the following case: $ sort -c unsorted_file 2> /dev/full 9) Other style changes, line length, empty line before return.

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.
