- These are all small, typically command-line utilities that I have found to be useful.
- All are compiled using the MinGW compiler package. This is an excellent, FREE compiler package which is based on the GNU compiler, but links to Windows libraries. I recommend the TDM distribution, to avoid certain issues with library accessibility.
NOTE: from September 2022, some of the files in this folder are built with 64-bit compiler, in order to support functionality in certain utilities.

ulocate - This was initially written for use under
Linux, as a replacement for the obtuse find
command. It also works in Windows consoles.
ulocate performs a case-insensitive search of all subdirectories below the
specified starting point for any filename containing the provided string.
Optionally, it can also search the PATH for the same criteria.
Last Update: July 28, 2017
ULOCATE.EXE, Version 1.15
Usage: ulocate [options] name_component start_path
This program displays all filenames containing a specified
name component, starting at directory [start_path].
Default start_path is current location.
output-format options:
-d show file date
-t show file time
-s show file size (short format)
-S show file size (byte format)
-xl l = width of size field for -S (default = 6)
-n show file name (default)
other options:
-v Verbose mode - show search paths
-b Debug mode - show other process information
-l follow symbolic links
-w match exact string (whole-word search)
-/ Use backslash vs forward slash for path elements
-p Search for name_component in the directories in the PATH variable
NOTE: This option replaces the normal ulocate functionality with
alternate functionality. In this mode, subdirectories are NOT searched!!
Options can also be placed in the ULOCATE environment variable

printf2 - source code for printf/sprintf, with floating-point support,
and no header-file dependencies, for use in embedded projects.
Last Update: October 08, 2013
Embedded firmware environments provide a variety of challenges to the
software developer. One of these challenges is that, typically,
there is no "standard output" device to display messages on, so the
archetypal printf function is not an option. However, the
sprintf function is often still very useful for generating
formatted strings. Unfortunately, in most embedded environments,
linking stdio libraries is not an option, so a non-stdio version of
sprintf is very handy - but find such a function is very
challenging, especially if floating-point support is required!!
In 2002, Georges Menie distributed a version of
printf
which had no stdio/stdlib dependencies, and seems to support all of the
various obtuse printf syntaxes.
His code is clean, short, efficient, and builds on modern gcc
with almost no warnings!
Furthermore, it is distributed under
LGPL, which means it can be used freely by anyone, for any purpose!
The only option missing from his function was floating-point
support, which I need in my ARM9 implementation, so I added that
capability to it. This version has no dependencies on any
standard headers or libraries.
Updates:
- 12/02/09 - fixed floating-point bug related to padding decimal portion with zeroes.
- 03/19/10 - pad fractional portion of floating-point number with 0s
- 07/20/10 - Fix a round-off bug in floating-point conversions ( 0.99 with %.1f did not round to 1.0 )
- 10/25/11 - Add support for %+ format (always show + on positive numbers)
- 01/19/12 - fix handling of %f with no decimal; it was defaulting to 0 decimal places, rather than 6 in printf.
- 05/10/13 - Add
stringfn()function, which takes a maximum-output-buffer length as an argument. Similar tosnprintf() - 09/28/13 - Fix bug in printchar(), which was using a fixed length test that was not appropriate for general use
- 10/08/13 - Add support for signed/unsigned long long (u64/i64)
serial_enum - Uses standard Windows/Win32 methods to enumerate serial devices
Last Update: February 02, 2015
This is the Microsoft-approved method to enumerate all serial ports
on a machine, including USB-serial devices. In addition to listing
all the ports, it will report which ports can be opened (i.e., are
available for use). Also added an option to display the Device Name,
which can be passed to CreateFile().
rgb2cref - convert RGB value into hex/decimal form
Last Update: July 26, 2020
This is typically to aid in updating syntax-highlighting values for programming editors
cline - generate argc/argv data from command-line input

arg 2: 1
arg 3: 2
arg 4: 3
hex_dump - Read data and display as both binary and ASCII data
Last Update: August 15, 2017
This displays a data file in standard hex-dump format, comprising address + hex_data + ascii_data, looking like this:
007A0: 0C 89 5C 24 08 89 5C 24 04 C7 04 24 EE 30 40 00 | .?\$.?\$.?.$?0@. |
mrna2protein - parse an mRNA nucleotide sequence, and output corresponding
protein codes, in either 3 or 1 character format.
Last Update: May 09, 2020
Usage: mrna2protein -options CODON_SEQUENCE
Options:
-3 means output 3-character protein code (default)
-1 means output 1-character protein code
-t means assume template (3') DNA strand (default is sense (5') strand)
Note regarding CODON_SEQUENCE :
5' prefix and 3' suffix should *not* be included !!
Only [A,U,G,C] characters are valid
readall - list all files specified by a filespec with wildcards
Last Update: October 12, 2020
List all files specified by a filespec with wildcards.
This can be used as a template file for reading text files and
doing various tasks.
ascii - Displays an ASCII table, in decimal, hex and ASCII, for all 256 characters
Last Update: August 10, 2017
apptest - This inappropriately-named file demonstrates two common WinAPI tasks
Last Update: June 24, 2018
This console application demonstrates two common WinAPI tasks:
- Use printf() to output UNICODE messages to the console
- Display various Windows system/user directories
dms2dd - Convert between degrees/minutes/seconds and decimal degrees
Last Update: September 30, 2010
Usage: dms2dd input_value
Enter dms as degrees.minutes.seconds
Enter dd as integer_degrees.fractional_degrees
If dms2dd sees two decimal points in the input,
the value will be treated as dms, and dd will be calculated and output.
If dms2dd sees one decimal points in the input,
the value will be treated as dd, and dms will be calculated and output.
mortgage - Performs mortgage calculations
Last Update: December 23, 2011
Usage: MORTGAGE principle interest number_months overpay
In normal operation, this program computes the monthly payment, and payment summary table, for a loan with the input parameters.
Alternate mode: If number_months is 0, overpay is treated as the payment amount, and this program will // calculate and display the number of months required to pay off principle.
Also, if overpay is greater than payment, then overpay is treated as total payment amount, and overpay is calculated from that.
prime64 (formerly prime32)- calculates factors of a number, or reports if input is prime
Last Update: October 24, 2022
PRIME64.EXE - Written by: Daniel D. Miller
This program determines whether a number is a prime,
then displays either the number or its factors.
Note: converting to 64-bit build, sped up handling of number which had a factor that was greater than 32 bits, by about 25%.
beer_cals - Estimates calories of ale
Last Update: September 22, 2015
Estimates calories of ale, from both alcohol and carbohydrates, based upon volume and alcohol content. Volume may be input in milliliters or ounces. Carbohydrates are calculated at 4 grams/ml of ale, which is not at all a good approximation, but I don't know any better method.
makedepend - C/C++ makefile-dependency generator
February 02, 2007
This is the version of makedepend which is distributed with Xfree86. It is Copyright (c) 1993, 1994, 1998 The Open Group and has a free-distribution message in each source file. I made a couple of trivial changes to the source to make it compile with modern gcc, but otherwise it still works superbly and needs no changes.
To use this utility, make the following changes to your makefile:
- Add this line to the end of the makefile:
# DO NOT DELETE - Add a rule for running makedepend:
SRCS=file1.cpp file2.cpp file3.cpp
depend:
makedepend -I. $(SRCS)
- run
make depend
to update the dependencies.
That is it!! Your makefile now has the appropriate dependency list.
