I'm moving an email conversation to here.

I am enhancing the Generate Cover plugin to support template driven expressions from a text input field. I thought it would be nice if I changed the input to be a multiline QTextEdit, thereby allowing the user to do multiline expressions like:

Genre: {tags}\n
Published: {pubdate}

However the problem I have is that composite_formatter.safe_format() strips newline characters out. Now if I substitute in something else like <br/> it will work, but then it will blow up if you try to use a multiline complex {} expression.

Any suggestions? I need something that template formatter won't strip out that I can split on afterwards, but that won't cause multi-line formulas to blow up...

Or do we just tell users not to do multi-line formulas?
