Just a little question:
I have a text inside an EditText area.
Every time the program executes the following lines:
ft = open( filename, "w")
puts( ft, getText( fTextArea))
close( ft)
each text line is "enriched" by one more Line Feed, that is | 0D 0A |
characters.
After four such save operations (and reload), every line results spaced four
times
(in a normal editor),
while it shows in the EU TextArea 4 unreadable symbols.
The whole file was read with the simple:
data = get_bytes( fh, dirinfo[1][D_SIZE])
I tried then the more laborious formula:
while 1 do
line = gets(fh)
if atom(line) then
exit
end if
data &= line[1..length( line)-1]
end while
and that problem does not repeat, but the text lines are no more spaced as due
by
the Line Feed. All the text flows like a single line.
I think the EditText expects {0D, 0A} or {0A, 0D} at the end of each line. So
after removing the last character of each line, try appending "\n\r" or "\r\n". I
think one of those should do it.
<code>
end_of_line = "\n\r" -- or "\r\n"
while 1 do
line = gets(fh)
if atom(line) then
exit
end if
data &= line[1..length( line)-1] & end_of_line
end while
</code>
If I cut the end_of_line (0D 0A) and then I add the same, the problem remains
unchanged.
I think that the real problem begins when I save the text,
not when I load it; cutting the last byte was just an attempt...
Who adds the CR or LF to the original text?
Thanks again.
