HTML, text files, and CRLF's

[Janet]


a$ = httpget$("http://runbasic.wikispaces.com/space/showimage/USFDAMedSafety.txt")

cssid #filler, "{width: 500px; height: 100px}"
cssid #textContainer2, "{background-color: rgb(255 255 192); border-style: ridge; width: 500px; height: 400px; overflow: auto}"

cls: print: print
print a$
print: print

div filler: end div

textarea #textContainer1, a$

div filler: end div

div textContainer2
print a$
end div

end

Inside the div, the line breaks aren't recognized. I assume this is because html requires </br> for a line break. Is there a way I can save and/or read a text file such that line breaks will be preserved inside the div?

I tried, unsuccessfully, to save the file to disk as a temp file (using Alyce's method with her httpget$ / loadimage building block demo), hoping to use line input. I'll go reread the threads and demos and see if that's possible.

Thank you Janet, you have solved my problem on how to resize a textarea and change its font. For some reason I could not get css styles to work earier.

Sorry but I can't answer your problem for now!

Mike ;D

EDIT: No, I realise now you created a division which looked like a textarea. Sorry Janet!

First choice would be to open the file, input each line, and then output it (appending a <br />). If you want to use a string in memory, use a find/replace function (there's one on the LB Wiki) to replace each CRLF with a CRLF and then a <br /> tag.

Can you give the code to open the file and then input each line? I couldn't do it. The only way I can read an online file is to put all contents into one string with the httpget$ command. Hmmm... let me work on parsing that string....

Sorry I couldn't be more helpful myself.

Janet, for working with files fetched via HTTP, you'll need to save the results of an httpget$() call to a temporay file. I was going to share a function that does part of this for you, but it doesn't seem to work in beta 4. Perhaps I should look into writing an HTTP utility module.

Of course, you could always use the in-memory method...

I wonder why you can write an image file (jpg for example) to file on disk, but not a text file? Thanks for trying, Bill. At least I know I should put together a quick workaround and then get on with the rest of the program.

My quick workaround

a$ = httpget$("http://runbasic.wikispaces.com/space/showimage/USFDAMedSafety.txt")

nLines = 0

For i = 1 to Len(a$)
If Asc(Mid$(a$, i, 1)) = 13 Then
nLines = nLines + 1
End If
Next i

Dim a$(nLines)
ct = 1
pos = 0
For i = 1 to Len(a$)
If Asc(Mid$(a$, i, 1)) = 13 Then
a$(ct) = Mid$(a$, pos + 1, i - pos)
pos = i
ct = ct + 1
End If
Next i

cssid #textContainer2, "{background-color: rgb(255 255 192); border-style: ridge; width: 500px; height: 400px; padding: 20px 20px 20px 20px; overflow: auto}"

cls

div textContainer2
For i = 1 to nLines
Print a$(i)
Next i
end div

end

In MSIE, things look okay. In FireFox, things look.... different. The DIV background is not colored, and the text paragraphs do not wrap to fit the DIV -- the horizontal scrollbar kicks in, and each paragraph is a single line running off invisibly past the DIV frame edge. I can't figure out why FireFox's line-wrap doesn't work.
