content-type woes and the evils of /n -- any advice?

Hello Everyone!


I've written a file-converter that grabs what is essentially a CSV file,
and spews it out in a reformatted fashion. Each line of the
"CSV" is terminated by a newline, and must be reproduced in the
conversion. However, I've hit a wall.


The converter works flawlessly when run from the command line. The
problem is that the web version of the converter, which uses the same
code as the command-line version, does not reproduce the newlines
properly, and thus, the downloaded file does not have the newlines where
they should be -- that is, there are no newlines in the downloaded file
at all.


Just to give you an idea of what I'm doing...


The web version of the converter loads the file that needs to be
converted into @converto, coverts the data, and then the following is
passed to the browser:


print
"Content-type:text/html\n";

print
" Content-Disposition:attachment;filename=convertedFile.txt\n\ n ";

print @converto;


Is there a way to have the newlines faithfully reproduced? I've tried
various Content-encodings (i.e. quoted-printable, base7, even binary) and
the results are always the same (no newlines reproduced). Attempts to
force newlines with a for loop, i.e.:


foreach (@converto) { print "$_\n"; }  # I've tried:
\n\r  \n\n   \n\r\n\r


Will produce random newlines, but the converted file remains
"broken".


Any advice would be super-appreciated...


Thanks!


Todd

if you're trying to put line breaks into html content that will be displayed
in a
browser, try using "
". e.g.,

foreach (@converto) { print "$_
"; } # browser line break
