Cweed is a C source file weeder written in Win32Forth.
It only changes whitespace (formatting) and does not
otherwise change the content of the file.
This is analogous to weeding a garden, where the
plants are left untouched but the bits between may be seriously modified.
Cweed is an experiment in specifying a coding standard
in the form of an executable program.
Code prettifier for C and header files. Converts tabs to spaces,
re-formats, checks for Lint errors.
Creates
a folder report listing files and their formatting health status.
Shows
the CRC32 and MD5 hashes for each file.
Lots
more features too...
colorForth is a simple dialect of Forth created by the inventor
of Forth, Chuck Moore.
cf2019 is a
distribution that runs on a Windows PC in bochs, or natively from a USB drive.
Download cf2019_Issue_2019Apr04.exe colorForth system packaged with Bochs.
Double left click ( run ) go.bat to run the cf2019.img image in the
bochs PC emulator.
Documentation
: cf2019_colorForth.pdf
cf2019 uses BIOS calls to access the USB drive, so it is no longer
necessary to have a floppy disk drive to run natively!
Full assembler source file, NASM
assembler, colorForth source and batch
files to create the colorForth image, and run
it in the bochs emulator.
Real colorForth running on (just about) any Windows PC.
bochs is available from http://bochs.sourceforge.net/
Thank you to all the bochs developers...

Win32Forth6v05H 2019 Mar 02
Win32Forth6v05H.7z
( and Win32Forth6v05H.zip
zip version ) , the Win32Forth system used to create win32for.exe, as supplied
in the Cweed packages.
The
‘H’ is for Howerd, although I have kept as much of the original V6.05 as
possible.
This
version of Win32Forth runs under Windows 7 and 10 and does not trigger my
anti-virus program.
It
also includes bug-fixes from Rod Oakford ( including one in the ExtSources kernel that made a zero sized window when
running on a new computer ) - thanks!
I
have kept the original help file by Tom Zimmer et al. but moved it to load from
the local directory without having to have the source tree present.
This
means that it works with the Cweed package. I merged changes in the OS
detection words from V6.14 so that it recognises Windows 7, 8 and 10.
I
have also added some aliases such as
loc for
locate , to locate a word’s source,
\\ for \S to end compilation of a file
and
some new words :
g to invoke the editor, and
tt that, if you are in
directory Cweed, will load file Cweed.f
Show{ which
compiles the text following it until End} like .” , and
zCompile{ which compiles the text following it until
End} as a null terminated string.
Useful
for helptext.
Type loc
Show{ to view the source code, and g to
open the editor.
\ Average.f 2014 Nov 07
Running averaging of n data readings.
Howerd Oakford www.inventio.co.uk
\ Uses a buffer size that is a power of 2 for
efficiency
\ Calculates a running total by adding the
current reading and subtracting the
\ n'th reading, so
looping over many values is not required - see UpdatePulses
\ You can extract averages over a different period of time from the same average buffer.

Unzip all the files from USBclarify.zip into a folder,
irun SwiftForth and in the SwiftForth console use cd c:\yourfolderpath and type include USBclarify.f , or click on | File | Include | and
select the file USBclarify.f , then
type USBclarify <cr>
USBclarifyFull.f this file includes MD5.f
and usb.ids in-line – open it in your browser, ctrlA ctrlC then paste it into a SwiftForth
console with ctrlV, wait half a minute then type USBclarify <cr>
Just for fun, to see how it can be done - it’s one big
file, so please be patient :-)
USBclarify.f
V1.0 2014 May 14 Howerd Oakford www.inventio.co.uk
Displays when a USB device is connected and
disconnected, including which COM port a USB serial device is assigned to
Demonstrates how to use Windows device notifications
Defines HID and other constants and structures,
including support for GUIDs
Compile using SwiftForth, available from www.forth.com
The file usb.ids from
http://www.linux-usb.org/usb.ids must be in the local folder in
order to compile this program.
Thank you to the Linux guys for making this
information available :-)
The USBloader system is designed to make it easy to make any USB disk
drive bootable.
This allows you to run your choice of operating system on your computer,
from a USB drive.
Program execution is in Real Mode on an 80x86 PC, 80386 32 bit or higher
is required.
USBloader supersedes USBboot which is no longer
supported.
Download : USBloader2013Apr08release.exe self extracting zip file or USBloader2013Apr08release.zip zip
file.
Disclaimer : using USBloader.exe to make a USB drive bootable should not affect the
other files on the drive.
Use it at your own risk, and backup up everything on
your drive, or use a brand new one, just in case…
Now with new Floppy Disk Formatting features : press
ctrlF4 to convert the cfUSB.img file into a floppy
disk image and copy it to the inserted drive.
This can be either a USB floppy disk drive or USB
drive, in either case the disk will be re-formatted and all data will be lost.
There are two warnings before this happens…
Includes a FAT32 file system boot loader written in
NASM assembler
Corrected two typos in the HDLC CRC16 calculation in
Forth and
added two new CRC16 calculations :
crc16hdlc.f
crc16.zip (
the zip file now contains all three CRC16 files )

*****************************************************************************

\ 16 bit FCS lookup table per RFC1331
\ Thanks to :
\
http://www.mavi1.org/web_security/cryptography/hashes/crc/crc-16-hdlc.c
\ Note that this code defines "#define FCSGOOD 0xF0B8"
\ whereas I define "$0F47 constant CRC_VALID" which is
bitwise inverted.
\ This is because CRC16 returns the actual value to be sent in an HDLC
packet
\ Also note that at least one online CRC calculator does not include
this CRC.

PCIdev PCI device
viewer. Even works under WinXP/2K/NT (with some
help!) This program may be of special interest to potential colorForth users to debug troublesome
hardware...
PPP.com is a DOS based program
to analyse, display and create PPP and Internet protocols. PPP.com is the
current evolution of a general purpose scripting environment, adapted to the
Point to Point Protocol. Currently it can open a PPP connection to an ISP and
send DNS, ICMP, UDP or TCP packets to any IP address on the Internet. PPP.com
has not been optimised for program size, as it is a 16 bit Forth program, and
nearly fills up the maximum 63K bytes allowed for a .com program. This includes
4K of help text, roughly 3K of protocol descriptor text, an editor, 8086
assembler and Forth compiler. It supports five tasks, two of which monitor PPP
and IP packets on each of COM1 and COM2 serial ports. It is programmed in a 16
bit DOS 8086 Forth to allow easy porting to 8 or 16 bit embedded processors.
Cweed is a C source
file weeded and scanner. It only changes whitespace (formatting) and does not
otherwise change the content of the file. This is analogous to weeding a
garden, where the plants are left untouched but the bits between may be
seriously modified. Cweed is an experiment in specifying a coding standard in
the form of an executable program. Cweed is also useful for
scanning a file for control characters, removing tabs, or just viewing what is
actually there, not processed and formatted by an editor.
cfdos is a DOS program
to display colorForth pre-parsed
source blocks. This program will work on any computer that runs or emulates
DOS, and allows you to view colorForth source, in both
normal and "colour blind" mode. It features a file listing utility
(F6) which displays all files of type *.BLK in the same directory, and can copy
them to a formatted floppy disk. colorForth Explorer Edition is the latest colorForth stand-alone
operating system, packaged together with a Windows/DOS program to display colorForth source and create
bootable floppy disks.
Don't
be deceived by the fact that colorForth
boots from a floppy - this is an experimental state-of-the-art operating system
for a PC.
