Web browser

[+Philsan]

I remember that many years ago I was able to display web pages with Dragoncart and Contiki web browser.

 

Is it possible or would it be possible to to the same with FujiNet?

 

Thanks!

Yes, it's one of the reasons I am working so hard to get N: working fully, as the FujiNet will be able to do a TON of ESP32-side processing to make writing a web browser on the Atari, MUCH EASIER. (In BASIC even, if so wanted.)

I've been fiddling around in BASIC making a 'Web LISTer'. Most of the work is done in a php script on a server which grabs a url and reformats it for display on the Atari. It's currently very crappy and just scrolls the entire page without stopping. Links are not supported. Also, the FujiNet does not currently handle chunked http so any large pages wont load. Here is a view of fujinet.online/support:

[mozzwald]

I put the Web LISTer up on fujinet.online tnfs at networking/www.atr. Keep in mind it's pretty bad, buggy for sure  After booted to Atari BASIC, just: RUN"D1:WWW.ATR"

I always get "That's not a web page" message.

Perhaps I am entering wrong URL or URL in wrong format.

Same

 

I even tried hard coding the address into the basic program and verifying the site works with frogfind.

URL format should be all lowercase like so:

https://fujinet.online 

or

https://en.wikipedia.org/wiki/leg

 

Special characters are not supported in the URL either as there is no urlencode functionality. Large content length pages still do not work due to the inability of chunked transfers problem in FujiNet firmware.

I tested the two URLs but nothing happened.

 

SIO light turned on for circa 10 seconds, then READY appeared.

Interesting. Sounds like it got chunked. Both of those sites worked for me. You can verify by watching the debug output and the status frame tells if it is chuncked.

Scratch that; spotted the (massive) flaws after posting.

Now that there's some support for chunked http transfers, my silly site scroller should work with long pages. (tnfs or www) https://fujinet.online/tnfs-data/networking/www.atr

 

Currently the script pauses for each screen fill and if you wait too long to press return, the next page will be out of sync or it will keep scrolling the same page forever. I suspect the buffer on fujinet is getting overwritten/out of order because we aren't reading it fast enough.

 

anyhow, it's a good way to test the new chunked support

It works!

It would be nice automatic lower case when you enter URL.

What's the purpouse of the first INPUT, before URL INPUT?

I can add it if someone shows how to do it. Just did a quick search and couldn't find out how.

The autorun seems to add a carriage return when it first loads the script so without the input/pause it would press return with an empty url

Here is a routine that converts a string from upper case to lower case.

I adapted a routine that converts a string from lower case to upper case found on the book Atari BASIC Faster and Better.

 

100 DIM URL$(50)
110 INPUT URL$
120 GOSUB 1000
130 PRINT URL$
140 END
1000 FOR X=1 TO LEN(URL$):IF ASC(URL$(X,X))>64 AND ASC(URL$(X,X))<91 THEN GOSUB 1020
1010 NEXT X:RETURN
1020 URL$(X,X)=CHR$(ASC(URL$(X,X))+32):RETURN

I think you can gain a little speed by reducing the number of lookup / ASC calculations:

 

1000 FOR X=1 TO LEN(URL$):Q=ASC(URL$(X,X)):IF Q>64 AND Q<91 THEN GOSUB 1020
1010 NEXT X:RETURN
1020 URL$(X,X)=CHR$(Q+32):RETURN

Thanks, that works!

Indeed, it seems a little faster.

 

I've added this to the ATR as well as changed the url to fujinet.online/fujifind
