Brad,

Not having access to UI-View.... give the following URL a try to see if it works for you.

http://cumulus.tnetweather.com/WXNOW.txt
or
http://cumulus.tnetweather.com/wxnow.txt

I would think that it would be easy for Steve to just generate a file like this. But in case that is not in the cards, it is easy to cause the generation of the same from the server side of a PHP based server. You could do the same with an ASP (IIS) server too, but I am not familiar with the coding on that...

This method works using some .htaccess trickery... It requires mod_rewrite to be available to on the host.

The script is actually called WXNOW.php and it parses out the data from the realtime.txt file and outputs the text as you see it.

Code: Select all

To make the system respond to WXNOW.txt or wxnow.txt, I created a simple rewrite rule like:

Code: Select all

RewriteRule ^/?wxnow.txt$ /WXNOW.php [L]
RewriteRule ^/?WXNOW.txt$ /WXNOW.php [L]

This tells the server that if it sees a request for either WXNOW.txt or wxnow.txt, to rewrite the request to point to the PHP script instead. The visitor doesn't really see this, they just get the output of the script as if they had gotten just a plain old txt file.

Yes, I can easily generate one of those. The crucial information I'm missing is: What do I do with the file once I've created it?

Apologies again for the delay in getting back to you. For some reason when I log back in this thread isn't marked as "updated", and then I eventually lose it.

Steve: to answer your question, you only need to create it. In UI-View (or the other APRS programs that use it), I just specify the path to where it's been saved. If you want to include the option for me to specify *where* to put the generated file, all the better, but not critical.

TNETWeather: the sample you post is close except if I open it in Notepad, it's not seeing the line break after the time. It looks like you saved it with a Unix-style linebreak (LF only) instead of a DOS-style (CRLF).

I promise to log in more often and keep track of this. Apologies again for leaving you all hanging.

Brad.

OK - I'll put the code in to generate one.

TNETWeather: the sample you post is close except if I open it in Notepad, it's not seeing the line break after the time. It looks like you saved it with a Unix-style linebreak (LF only) instead of a DOS-style (CRLF).

It is not really ever saved, it is dynamically generated each time you hit it with a browser. I suppose it depends on what browser you are using.

Using MSIE, if you look at the source, it contains CRLF's for each line.



If you open it up with FireFox, it will only have LF's since that is how FF interprets it.

The script is actually outputting CRLF after each of the two lines.

When you look at via the browser itself, it won't appear to have any linefeeds since HTML browsers don't display line feeds only html linebreaks (<br/>) and the script is not outputting those.

[bpsmicro]

Curiously, if I do a "Save As" and put the .txt file directly only my local machine (IE of FF) and open in Notepad, it only sees the LFs. But View Source does indeed work as expected. I've never seen that before.
But no matter, I suspect UI-View would work either way, and since I'm not grabbing the file via a browser normally, it's a non-issue.

Now to eagerly watch for the next build.

Brad.

If you want to use that script, you don't need to wait for the next build.

This assumes that you have PHP on your local web server.
