Code of Conduct
This Code of Conduct is derived from the 10 Pāramitās of Theravadin Buddhism.
You can read more about them in Ṭhānissaro Bhikkhu’s Ten Perfections: A Study
Guide [0].
1. Generosity (Dāna)
Give contributions freely and willingly under the terms of the GNU Affero
General Public License, version 3 or later, or a compatible license.
2. Ethics (Sīla)
Do not use nonfree code or uncredited code in contributions. Do not contribute
code of dubious origins, such as code generated by large language models or
unlicensed snippets found online [1]. Do not take credit for others’
contributions. Make sure to utilize the copyright header and license notice on
source files to credit yourself and others for their work.
3. Renunciation (Nekkhamma)
Stay committed to the principles of simplicity and interoperability embodied by
the project. Keep your personal will and desire out of the project, for it can
only prove harmful to its success.
4. Wisdom (Pañña)
Look to established sources for standards, best practices, and important
implementation details when setting new precedence. Follow the existing
precedence where it applies.
5. Energy (Viriya)
Focus on the currently-open, currently-assigned, and currently-in-progress
issues, pull requests, and other endeavors in order to keep yourself and others
from being overwhelmed with responsibility, either from your zeal or your
negligence.
If you notice an issue, open an issue as soon as you can. If you see a neglected
branch, open a pull request or comment on an existing one, if applicable. Be
diligent in your commitment to making this project work.
6. Patience (Khanti)
Be patient with maintainers and other contributors. We all have our own lives
going on and may need significant time to get to things.
7. Truthfulness (Sacca)
Communicate honestly and openly. Do not embellish facts to get your way. Make
sure to let maintainers know about any issues along the way and keep ample
communication channels open.
8. Determination (Adhiṭṭhāna)
Stay focused on long-term objectives and cultivate attainment to that
achievement by utilizing to the fullest extent possible the tools available to
you for managing the workload.
9. Loving-Kindness (Mettā)
Treat everyone with respect, even if they treat you poorly. This does not mean
you have to put up with abuse, but make sure to respond with kindness and with
love in your heart. Support and uplift maintainers and other contributors with
your words and actions.
Do not use angry or hateful language toward contributors, such as demeaning
phrases and slurs. Make sure that if you do not know the pronouns of a
contributor to ask for them and, in the meantime, use gender-neutral they/them
or equivalent pronouns.
10. Equanimity (Upekkhā)
Keep a balanced perspective on all suggestions and contributions and make
judgements not from a place of ego and personal preference but on their
usefulness and suitability to the project. Make sure to keep an eye on the
bigger picture as implementing individual features may seem intuitive at first
but scale poorly in practical use. Keep a level head about your own work: it is
not shameful to make a mistake in this vein, and fixing it usually leads to
more insight.

.SH DESCRIPTION
.SH USAGE
Perform precise read and write operations on files. This utility is useful for
reading and writing binary data to and from disks.
The
.B -i
option takes a path as an argument to open and use in place of standard input.
The
.B -o
option does the same in place of standard output. Dj does not truncate output
files and instead writes over the bytes in the existing file.
.PP
The
This manual page uses the terms \(lqskip\(rq and \(lqseek\(rq to refer to moving
to a specified byte by index in the input and output of the program
respectively. This language is inherited from the
.BR dd (1p)
utility and used here to decrease ambiguity.
When seeking or skipping to a byte, writing or reading starts at the byte
immediately subsequent to the specified byte.
.\"
.SH OPTIONS
.IP \fB-i\fP
Takes a file path as an argument and opens it for use as an input.
.IP \fB-b\fP
Takes a numeric argument as the size in bytes of the input buffer, the default
being 1024.
.IP \fB-s\fP
Takes a numeric argument as the number of bytes to skip into the input
before starting to read. If the standard input is used, bytes read to this point
are discarded.
.IP \fB-o\fP
Takes a file path as an argument and opens it for use as an output.
.IP \fB-B\fP
Does the same as
.B -b
option takes a numeric argument as the size in bytes of the input buffer and
the
.B -B
option does the same for the output buffer, the default for both being 1024
bytes, or one kibibyte (KiB).
.PP
The
.B -s
option takes a numeric argument as the number of bytes to skip into the input
before starting to read, and the
.B -S
option skips a number of bytes through the output before starting to write from
the input. If the input is a stream the bytes are read and discarded. If the
output is a stream, nul characters are printed.
.PP
The
but for the output buffer.
.IP \fB-S\fP
Seeks a number of bytes through the output before starting to write from
the input. If the output is a stream, null characters are printed.
.IP \fB-a\fP
Accepts a single literal byte with which the input buffer is padded in the event
of an incomplete read from the input file.
.IP \fB-A\fP
Specifying this option pads the input buffer with null bytes in the event of an
incomplete read. This is equivalent to specifying
.B -a
option takes one argument of one byte in length and pads the input buffer with
that byte in the event that a read doesn't fill the input buffer, and the
.B -A
option takes no arguments and pads with nuls.
The
.B -c
option specifies an amount of reads to make, and if 0 (the default) dj will
continue reading until a partial or empty read.
.PP
On a partial or empty read, dj prints a diagnostic message (unless the
.B -q
option is specified) and exits (unless the
.B -n
option is specified, in which case only two consecutive empty reads will cause
dj to exit).
At exit, usage statistics are printed unless the option
.B -q
is specified a second time. The
.B -H
option will make these diagnostics human-readable.
with a null byte instead of a character.
.IP \fB-c\fP
Specifies a number of reads to make. The default is 0, in which case the
input is read until a partial or empty read is made.
.IP \fB-d\fP
Prints invocation information before program execution as described in the
DIAGNOSTICS section. Each invocation increments the debug level of the
program.
.IP \fB-H\fP
Prints diagnostics messages in a human-readable manner as described in the
DIAGNOSTICS section.
.IP \fB-n\fP
Retries failed reads once before exiting.
.IP \fB-q\fP
Suppresses error messages which print when a read or write is partial or
empty. Each invocation decrements the debug level of the program.
.\"
.SH STANDARD INPUT
The standard input shall be used as an input if no inputs are specified or if
one or more of the input files is \(lq-\(rq.
.\"
.SH STANDARD OUTPUT
The standard output shall be used as an output if no inputs are specified or if
one or more of the input files is \(lq-\(rq.
.\"
.SH DIAGNOSTICS
The
.B -d
option prints all information, user-specified or otherwise, before program
execution.
.PP
When dj exits, by default statistics are printed for input and output to
standard error in the following format:
.PP
.R {records read} {ASCII unit separator} {partial records read}
.R {ASCII record separator} {records written} {ASCII unit separator}
.R {partial records written} {ASCII group separator} {bytes read}
.R {ASCII record separator} {bytes written} {ASCII file separator}

unless the
.B -n
option is specified.
By default, statistics are printed for input and output to the standard error in
the following format:
.RS
{records read} {ASCII unit separator} {partial records read}
{ASCII record separator} {records written} {ASCII unit separator}
{partial records written} {ASCII group separator} {bytes read}
{ASCII record separator} {bytes written} {ASCII file separator}
.RE
This format for diagnostic output is designed to be machine-parseable for
convenience. For a more human-readable format, the
.B -H
option may be specified. In this event, the following format is used instead:
.RS
{records read} '+' {partial records read} '>' {records written}
'+' {partial records written} ';' {bytes read} '>' {bytes written}
{ASCII line feed}
.RE
If the
.B -d
option is specified, debug information will be printed at the beginning of
execution. This output contains information regarding how the program was
invoked. The following example is the result of running the program with
.B -d
as the only argument:
.RS
argv0=dj
in=<stdin> ibs=1024 skip=0 align=ff count=0
out=<stdout> obs=1024 seek=0 debug= 3 noerror=0
.RE
In non-recoverable errors that don\(cqt pertain to the read-write cycle, a
diagnostic message is printed and the program exits with the appropriate
.BR sysexits.h (3)
status.
.\"
.SH BUGS
If
.B -n
is specified along with a specified count, actual byte output may be lower than
expected (the product of the count multiplied by the input block size). If the
is specified along with the
.B -c
option and a count, actual byte output is the product of the count and the input
block size and therefore may be lower than expected. If the
.B -a
or
.B -A
options are used this could make data written nonsensical.
.PP
options are specified, this could make written data nonsensical.
.\"
.SH CAVEATS
Existing files are not truncated on ouput and are instead overwritten.
Many lowercase options have capitalized variants and vice-versa which can be
confusing. Capitalized options tend to affect output or are more intense
versions of lowercase options.
.\"
.SH RATIONALE
Dj was modeled after the dd utility specified in POSIX but adds additional
features: typical option formatting, allowing seeks to be specified in bytes
rather than in blocks, allowing arbitrary bytes as padding, and printing in a
format that's easy to parse for machines. It also neglects character
conversion, which may be dd's original intent but is irrelevant to its modern
use.
This program was based on the
.BR dd (1p)
utility as specified in POSIX. While character conversion may have been the
original intent of
.BR dd (1p),
it is irrelevant to its modern use. Because of this, this program eschews
character conversion and adds typical option formatting, allowing seeks to be
specified in bytes rather than in blocks, allowing arbitrary bytes as padding,
and printing in a format that\(cqs easy for machines to parse.

With the assumption that tools will output data separated with ASCII field
separators, there is a need for the ability to modify select fields in this data
easily and quickly.
The idea for this utility originated in the fact that the GNU

utility contains a
.B -h
option which enables human-readable units in file size outputs. This

.SH NAME
intcmp \(en compare integers
.\"
.SH SYNOPSIS
intcmp
.RB ( -eghl )
.RB ( -egl )
.RB [ integer ]
.RB [ integer... ]
.SH DESCRIPTION
Compare integers to each other.
.\"
.SH OPTIONS
Intcmp compares integers.
.SH USAGE
The -e option permits given integers to be equal to each other. If combined
with -g or -l, only adjacent integers in the argument sequence can be equal.
.PP
The -g option permits a given integer to be greater than the following integer.
.PP
The -l option permits a given integer to be less than the following integer.
.PP
It may help to think of the -e, -g, and -l options as equivalent to the
infix algebraic “=”, “>”, and “<” operators respectively, with each option
putting its symbol between every given integer. For example,
.R intcmp -l 1 2 3
is equivalent to evaluating "1 < 2 < 3".
.IP \fB-e\fP
Permits given integers to be equal to each other.
.IP \fB-g\fP
Permits a given integer to be greater than the following integer.
.IP \fB-l\fP
Permits a given integer to be less than the following integer.
.\"
.SH EXAMPLES
It may help to think of the
.BR -e ,
.BR -g ,
and
.B -l
options as equivalent to the infix algebraic \(lq=\(rq, \(lq>\(rq, and \(lq<\(rq
operators respectively, with each option putting its symbol between every given
integer. The following example is equivalent to evaluating \(lq1 < 2 < 3\(rq:
\"
.RS
intcmp -l 1 2 3
.RE
.\"
.SH DIAGNOSTICS
Intcmp exits 0 for a valid expression and 1 for an invalid expression.
.PP
Intcmp prints a debug message and exits with the appropriate sysexits(3) error
code in the event of an error.
The program will exit with a successfully for a valid expression and with an
error code of 1 for an invalid expression.
In the event of an error, a debug message will be printed and the program will
exit with the appropriate
.BR sysexits.h (3)
error code.
.\"
.SH BUGS
There are multiple ways to express compound comparisons; “less than or equal
to” can be -le or -el, for example.
.PP
The inequality comparison is -gl or -lg for “less than or greater than”; this
is elegant but unintuitive.
.PP
-egl, "equal to or less than or greater than", exits 0 no matter what for valid
program usage and may be abused to function as an integer validator.
Use str(1) instead.

.\"
.SH DESCRIPTION
Mm catenates input files and writes them to the start of each output file.
Catenate input files and write them to the start of each output file or stream.
.\"
.SH OPTIONS
Mm, upon receiving the
.B -a
option, will open subsequent outputs for appending rather than updating.
.PP
The
.B -i
option opens a path as an input. Without any inputs specified mm will use
standard input. Standard input itself can be specified by giving the path '-'.
.PP
The
.B -o
option opens a path as an output. Without any outputs specified mm will use
standard output. Standard output itself can be specified by giving the
path '-'. Standard error itself can be specified with the
.B -e
option.
.PP
The
.B -u
option ensures neither input or output will be buffered.
.PP
The
.B -n
option tells mm to ignore SIGINT signals.
.IP \fB-a\fP
Opens subsequent outputs for appending rather than updating.
.IP \fB-e\fP
Use the standard error as an output.
.IP \fB-i\fP
Opens a path as an input. If one or more of the input files is \(lq-\(rq or if
no inputs are specified, the standard input shall be used.
.IP \fB-o\fP
Opens a path as an output. If one or more of the output files is \(lq-\(rq or if
no outputs are specified, the standard output shall be used.
.IP \fB-u\fP
Ensures neither input or output will be buffered.
.IP \fB-n\fP
Causes SIGINT signals to be ignored.
.\"
.SH DIAGNOSTICS
If an output can no longer be written mm prints a diagnostic message, ceases
writing to that particular output, and if there are more outputs specified,
continues, eventually exiting unsuccessfully.
.PP
On error mm prints a diagnostic message and exits with the appropriate
sysexits.h(3) status.
If an output cannot be written to, an error occurs; however, exiting will be
deferred until writing to any other specified outputs completes.
.SH BUGS
Mm does not truncate existing files, which may lead to unexpected results.
When an error is encountered, a diagnostic message is printed and the program
exits with the appropriate
.BR sysexits.h (3)
status.
.\"
.SH CAVEATS
Existing files are not truncated on ouput and are instead overwritten.
.\"
.SH RATIONALE
Mm was modeled after the cat and tee utilities specified in POSIX.
The
.BR cat (1p)
and
.BR tee (1p)
programs specified in POSIX together provide similar functionality. The
separation of the two sets of functionality into separate APIs seemed
unncessary.

Due to precision constraints and the way floats are represented in accordance
with the IEEE Standard for Floating Point Arithmetic (IEEE 754), floating-point
arithmetic has rounding errors. This is somewhat curbed by using the
machine epsilon as provided by the Rust standard library to which to round
numbers. Because of this, variation is expected in the number of decimal places
rpn can handle based on the platform and hardware of any given machine.
