What is the Numbers.spin file on the object library web page?

Eric Smith

The Numbers.spin object seems to be some kind of binary file, rather than Spin source code. I thought maybe it was really a ZIP file, but apparently it isn't. Is it compiled code? If so, is the source available?

Thanks,
Eric

If you select the Propeller Library you can find Numbers.spin -- in its source form.

I just looked at it and it is a regular text file when I download it.
Here's the head of the file I get:

Are you talking about the Propeller Object Library page? That's where I've downloaded it from, and it is NOT source code. It's 85,894 bytes of something, though. Seems a little big for Spin source code.

Correct, thats where I got it from, looked at it with notepad, and cut and pasted the excerpt above.

That is the correct size of the file, I just verified it. It is large because it has alot of defined constants and documentation.

Very strange. I've downloaded it four times over the last several days, using wget. I get the same thing each time, which is a bunch of binary junk. So I just tried downloading it directly in Firefox, and I get the right thing. However, wget worked fine for more than twenty other files I've downloaded from the Propeller web pages (including the object library page), and from the forums.

I wonder why the Parallax web server would be providing different content for wget vs. Firefox? I've never seen that anywhere else, other than a few sites that explicitly reject all attempts to download using wget.

Anyhow, now I've got the right file. Thanks!
