I'm using vim and markdown for note taking.
Sometimes I find some useful information online, so I'll copy and paste into vim like below:
useful information line1 useful information line2 useful information line3 useful information line4
The annoying thing is, when I preview my markdown notes in html, these lines of texts are on the same line, because in markdown, to break a line, you must add two empty space at the end of the line.
How can I make vim automatically do this for me?
