Q&A  > data formatting


Description:

I want to print the contents of file line by line, with some additional formatting added to each line.

Here's what I've tried:

print <IN> , "<br/>\n" ;

<IN> in scalar context will only return one line per call, while in list context it will return a list of all the (remaining) lines in the file. Therefore, replace

print <IN> , "<br/>\n" ;
with
print map "$_<br/>\n", <IN>;

print "$_<br>\n", while <IN>;

You could also add a little $\ and local magic:

{ local $\ = "<br>\n"; print while <IN>; }
