Question

I have a sed script which will read in a file and, if a line begins with a space, remove the preceding line break and the matched whitespace so that that line and the preceding line are joined together.

sed -e :a -e '$!N;s/\n / /;ta' -e 'P;D' input_file_name.txt

Is there any way to have javascript do the same using regular expressions?

I am reading in the file using the HTML5 File API.

Easiest way is to read the whole file and then do a replace like:

content = content.replace(/\r?\n /g, ' ');

If the file fits in memory that is.
