The patch that added this was at my behest, it interpretted numbers in scientific notation. commit 34fc818d7edaefcc4a420f1da3b7002d35aa4103 Author: Jim Meyering Date: Wed Nov 15 21:42:47 1995 + Add support for sorting numbers in scientific notation. Include xstrtod.h. (struct keyfield): Add field: general_numeric. (usage): Describe -g option. (general_numcompare): New function. (keycompare): Use new comparison function when general_numeric flag is set. (set_ordering): Honor `g' flag. (main): Initialize and use new field. From Marcus Daniels . Marcus was working for us at the time. It is much slower than a normal sort, but if you need to sort scientific notation, it's real helpful. -- Russell Senior, President russ...@personaltelco.net ___ PLUG mailing list PLUG@lists.pdxlinux.org http://lists.pdxlinux.org/mailman/listinfo/plug

Rich, I think this is the solution.

Re: [PLUG] Sort numbers in 'natural' order
And the solution I'm aware of its too convert the dotted-quad to hex, sort it, and then convert it back. Or just use a programming library (perl, ruby, python, etc.) to do the sorting for you.

Re: [PLUG] Sort numbers in 'natural' order
I think this means sort sees the dot and assumes it is a string, which doesn't sort numerically.

[PLUG] Sort numbers in 'natural' order
Thought I found the correct option for sorting CIDR IP addresses, but apparently haven't. Using -g (general sort), -h (human readable sort), and -n (numeric sort) all leave xxx.11 following xxx.100. I thought one of these would put them in the same order as would us carbon forms. Is there such an option to sort that I've missed?

Re: [PLUG] QR Code generator with text label
OK, I have a boat load of info here, now to try it all and see what works, if any one has anymore recommendations I am all ears. What I want to have visible on the label is the QR code and a brief descrip- tion of the labeled item along with the P#. The QR code will have the full des- cription and the next step will be to capture the info into the parts db so that as we use parts off of the vehicles all we have to do is image the QR code and the part is noted and removed, but first step is to get the labels so that I can label the parts. Thanks folks for all of this great info.

I agree with Michael R. It sounds like a job for Imagemagick.

Scribus (since 1.4.3) has the ability to create QR codes in its barcode generator utility. You'd have to add the text line manually, though. And then export both as whatever form you want the ultimate output. I also believe LibreOffice can generate QR codes, although it might require installing an extension. ___ PLUG mailing list PLUG@lists.pdxlinux.org http://lists.pdxlinux.org/mailman/listinfo/plug

Here is a python script I wrote a while back that does something like
you want.. The QR code is a URL (https://example.com/stuff/rack/1) and
there is some txt "rack 1" underneath it. It has been a while since I
wrote it, so it looks like gibberish to me.
Bill
from PIL import Image, ImageDraw,ImageFont
import qrcode
qr = qrcode.QRCode(
version=3,
error_correction=qrcode.constants.ERROR_CORRECT_Q,
box_size=10,
border=4,
)
image = Image.new( "RGBA", ( 410, 480 ) ,"white");
qr.add_data('https://example.com/stuff/rack/1')
qr.make(fit=True)
img = qr.make_image()
print img.size
image.paste(img, (0,0), img.convert("RGBA") );
draw = ImageDraw.Draw(image)
font = ImageFont.truetype("/usr/lib/cinelerra/fonts/arial.ttf",60)
#font = ImageFont.load_default()
txt = "rack 1"
draw.text((100, 410), txt, (0,0,0), font=font)
image.save("qr.png")

Chuck, The python print() function will produce that text line. Put it all in a simple script and you can place the text either above or below the QR code.
