Web Browser

[DanTheMan]

Hi, DanTheMan here with another question... is it possible to modify Turing code to become a simple web browser? if so, could you post codes?

Just for the record, this is not a school project. This is just curiosity.

A while ago I made a Turing program that goes to a web address and gets the html. I forgot what how I did it though and it's not on this computer so I can't really help. But once you figure out how to download the html, you can make your own engine to render the pages.

BTW, I wouldn't recommend doing this. It will not work properly, it's a lot of work, and it won't even compare to any real web browsers.

If you meant like embedding an IE webpage in your program, then no you can't do that.

I'd bet you could. IE is built right into windows, and I'm pretty sure any program can attach an IE window into any other window. You'd have to write a C# program or something though, and start it with Sys.Exec()

I found some turing programs that do stuff over the local network (a chatroom i forget by who)

Although it works, it is painfully slow. Trying to make a webbrowser it might work, but it will probaly be so slow you'd think you are on dialup when it first came out on a computer with 2kb or ram.

If you are trying to get rid of the (i have) Bess block or website block, a browser change won't do it.

as it was mentioned, you could use Net module to download web pages, and then interpret them in a way that you want. Turing's Net is known to be buggy and/or slow, so a faster alternative might be to use something like curl to fetch the content, and then read from a local file.

[DanTheMan]

Well... I dunno what to say...

Yeah, but then you'd be running a C# program not a Turing one. I think he wanted to have IE in his actual Turing run window.

That's what I'm talking about, I think you can make a program attach an IE frame in any window (even ones that program didn't create).

I remember a stealth program that would put one in whatever window was active, that you could hide with a quick key stroke. The name escapes me though.

Either that, or just a turing window that has a web address bar that you can type into and open up the page in a web browser.

Hmm.. To open a page in a webbrowser, try:

Turing:

Sys.Exec("URL of webpage")

That might work (Can't remember if windows associates web addresses with the browser), if not it might be:

Turing:

Sys.Exec("explorer.exe 'path to webpage'")

[edit] The first should work, that's one of the examples on the help page: http://compsci.ca/holtsoft/doc/sys_exec.html

Turing lacks any access to the windows or IE API so it can not attach an IE window only open one but thats rather pointless (as you could open it in firefox or there default browser the same way).

Turing would still have no access to any of the content or pages being viewed in the browser and by no means would it be a web browser in Turing. It could be good to spam the user into viewing your webpage but it's not very partical for anything else.

Which is why, if you could do it, you'd have to write it in another language, and start it with Sys.Exec()

I just got an idea.

What I needed to do was just print the HTML on turing, so I have to find a way to print it. I made a program that opens the file and prints it on the screen, but I need to make it recognise the tags and print them on the screen.

code:

var fileNo : int var ch : char open : fileNo, "HTML.txt", get loop     get : fileNo, ch     put ch ..     if eof (fileNo) then         exit     end if end loop close : fileNo

If you want just very basic rendering, make it read until it gets to <body>, then print every character it does not between < and >.
Then, if you feel up to it, make <br> and <br /> end the line, <em> and <strong> change foreground colour, etc.

Witch makes the turing program just a short cut for a web broswer you wrote in another langue, you might as well skip turing all togther.

Going from HTML to the visual rendering you get with a browser is not a trival problem and would be a masive undertaking even for a basic text based browser.

If you realy want to make your own web broswer i recomend ditching turing and going to a langue that can use permade web browser engines like WebKit.
