sbase - suckless unix tools
===========================
sbase is a collection of unix tools that are inherently portable
across UNIX and UNIX-like systems.
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 18:36:13 +00:00
The following tools are implemented ('*' == finished, '#' == UTF-8 support,
Add audit-section to README Okay, so why another section? The finished-section applies to general feature-completeness and manual status. It somehow is not an indicator for general code- clarity, so the audited-column reflects a thorough audit of the underlying code and optimization. Take a look at the upcoming basename(1)-patch for an example on how this goes.

'=' == implicit UTF-8 support, '|' == audited):
Add an easier to edit "table" of tools in README We need to go through the tools and update this table to reflect current state.
2014-11-20 23:01:56 +00:00
Audit basename(1) 1) be stricter which number of arguments is accepted (1 or 2) 2) basename already returns a pointer to "." is argv[0] is "" 3) No need to check for *p != '/', because basename() only returns a string beginning with '/' which has length 1, so if strlen(p) == 1, the only way for suffix to be "evaluated" is for off to be > 0, being equal to suffix being "", but "" != "/". 4) don't calculate strlen twice for each string. Store it in a ssize_t and check if it's > 0.

Audit cat(1) 1) Fix usage ... spacing 2) use *argv instead of argv[0] in the idiomatic for-loop 3) Stop the naïve usage of "/dev/fd/0" and use plain stdin instead (This also makes error-messages more consistent). 4) Add newline before return 5) Remove comma in manpage

Audit cp(1) 1) Refactor the manpage, which has been a bloody mess, documenting fantasy-flags (-d for example) and add a STANDARDS section 2) fix usage() 3) sort ARG-block 4) Check return-value of stat() separately, so a lack of permissions doesn't tell the user "the directory doesn't exist", which could be a bit confusing. 5) Add empty line before return.

Audit head(1) 1) Use (s)size_t in head(). 2) BUGFIX: only check buf[len - 1] when len > 0, else there would be an overflow when getline returns 0 (which can happen) and a very potential segmentation fault. 3) fix error-messages. 4) update usage(). 5) argv-argc-style. 6) clear up the main loop with if (newline). 7) add newline before return.

Audit mkfifo(1) 1) Fix usage() 2) Group local variables 3) Idiomatic argv-loop 4) BUGFIX: When the m-flag is specified, POSIX clearly says: "Set the file permission bits of the newly-created FIFO to the specified mode value." This means, that if mkfifo() fails for some reason, it should not try to chmod() the given path (which has been fixed with the "else if") A simple testcase is: $ touch testfile; mkfifo -m 000 testfile; GNU mkfifo(1): ls -l testfile -rw-r--r-- 1 testfile sbase mkfifo(1): ls -l testfile ---------- 1 testfile 5) Add blank line before return

=* mktemp non-posix none
Audit mv(1) 1) Make argument-naming consistent with other tools (cp(1), ...) 2) style fixes 3) usage() fix 4) BUGFIX: Probably from the old non-arg.h days, the directory- check was only done when argc > 3, but with arg.h, this ignores the case when 3 arguments were given. This is actually a pretty serious issue and I'm glad it's fixed. 5) Moreover, be more verbose when stat() fails and make it clearer what the hell is going on at this checkpoint.
2015-03-04 22:22:43 +00:00
=*| mv yes none (-i)
Audit nice(1) 1) val is sufficient as "int" (read the standard) 2) BUGFIX: If getpriority fails, it returns -1 and sets errno. Previously, it would correctly catch the errno but not take care of the fact that by then val has been decremented by 1. Only change val if the getpriority-call has been successful. 3) Add LIMIT()-macro from st to increase readability. 4) setpriority returns < 0 on failure 5) Remove bikeshedding-comment. Read the standard if you wonder. 6) return-value trick from env(1)

Audit nohup(1) 1) no need to include sys/stat.h 2) remove the enum which just added a layer too thick on this simple program 3) argc-style, other style 4) weprintf instead of enprintf, then save the error-message of execvp before and return the proper status. 5) write consistent "not reached" comment.

=*| rm yes none (-i)
Audit rmdir(1) 1) style fix (don't arrange local variables) 2) BUGFIX: Previously, if ret was turned 1 for some folder, it would disable the p-flag for every following folders, which is not desired. Instead, the "else if" makes sure that the p-flag-section is only entered when the initial rmdir succeeds. 3) BUGFIX: Previously, the program would cancel with eprintf if it failed to remove one folder in the parent-pathname. This is not desired, as we have other folders pending. Instead, print a warning for the current failing parent-folder, set ret to 1 and break off the loop at this point. This allows to finish the other pending folders without issues.

Audit tee(1) 1) "duplicate" implies that you can only specify two outputs, "multiply" is a better word describing the functionality. 2) fix other wording in the manpage 3) fix usage() 4) reorder local variables 5) fix sizeof() style 6) we need argv later, don't increment argv and rather iterate over argc. 7) Improve error messages, print the filename which the write failed to instead of printing the buffer itself (how much sense does that make, printing 1024 Bytes of garbage?). Also, give the name of the function which failed.

Minor fix for README
2014-02-12 18:39:13 +00:00
The complement of sbase is ubase[1] which is Linux-specific and
Add initial README
2014-02-12 14:34:09 +00:00
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
README: document sbase-box-install rule
2015-02-28 14:40:16 +00:00
individual tools to sbase-box or run: make sbase-box-install
Add initial README
2014-02-12 14:34:09 +00:00
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.
