overgrown - trinity's harakit workshop “Seek not to walk the path of the masters; seek what they sought.”
Matsuo Basho
simple build, no dependencies except rust The Bonsai harakit utilities are a replacement for standard POSIX utilities
which aim to fill its niche while expanding on their capabilities. These new
tools are the result of the careful examination of the current state of POSIX
and Unix utilies. The Unix Philosophy of “do one thing and do it well” are their
core but they avoid clinging to the past.
The era of the original Unix tools has been long and fruitful, but they have
their flaws. This project originated from frustrations with the way certain
tools work and how other projects that extend POSIX dont make anything better.
This project will not follow in the footsteps of GNU; extensions of POSIX will
not be found here. GNU extensions are a gateway to the misuse of the shell. The
harakit utilities will intentionally discourage use of the shell for purposes
beyond its scope.
See docs/ for more on the specific utilities currently implemented.
Building
Harakit utilities require a POSIX-compliant environment to compile, including a
C compiler and preprocessor (cc(1) and cpp(1) by default), an edition 2023 Rust
compiler (rustc(1) by default), bindgen(1), and a POSIX-compliant make(1)
utility.
To build and install:
# pkg_add rust rust-bindgen
$ make $ make
$ make PREFIX="/your/preferred/location" install
To build with a different compiler than the default:
$ make CC=clang
$ make RUSTC=gccrs
To test the utilities:
$ make test
To remove all build and distributable files:
$ make clean

.TH SIMEXEC 1 2024-07-23 "Harakit-overgrown X.X.X"
.SH NAME
simexec \(en execute a program with argv
.\"
.SH SYNOPSIS
simexec
.B binary argv...
.SH DESCRIPTION
Execute a binary with a certain argv.
.SH CAVEATS
Non-binary programs cannot be executed on their own. The PATH environment
variable is not used and a valid pathname (relative or absolute) must be
specified.
.BR simexec (1)
requires caution.
.B argv
are not just the operands for the binary but in fact the direct
.B argv
it will receive in runtime;
the first argv entry is the program\(cqs name, and omitting this, though valid
use of
.BR simexec (1),
can break false assumptions made by programmers.
for example, the
.BR true (1)
implementation in the GNU coreutils project suffers a segmentation fault it is
given no argv[0].
While POSIX.1-2017 doesn't mandate there being an argv[0] per se, a Strictly
Conforming POSIX Application must pass an argv[0]. It has also been said that
those who do not pass an argv[0] are mean and nasty and smell of elderberries.
.BR simexec (1)
directly uses the
.BR execv (3p)
library function. It cannot execute shell scripts intelligently (via shebang).
It is inadviseable to use
.BR simexec (1)
to simply execute a program when other methods would suffice.
.\"
.SH DIAGNOSTICS
.BR simexec (1)
exits with the returned value of
.BR execv (3p),
which will be 255 if an error occurs in execution, such as the binary not being
found.
This is indistinguishable from the executed binary exiting with the same
status.
Simexec will print a error message and return the proper
.BR sysexits.h (3)
value if invoked in an invalid manner.
