Re: [Haskell-cafe] How to print the " character without the backslash

Hi

I have this basic question of how to print the character " without the backslash.

I'm trying to print html code, so i need " a lot.

giveHtml (Leaf (a,(b,c))) = "<frame src=\"\" name=\"" ++ [a] ++ "\" scrolling=\"No\" noresize=\"noresize\" id=\"" ++ [a] ++ "\" title=\"" ++ [a] ++ "\" />"

Can anybody give me a light here? Yes, use the fact that HTML (and Javascript) both allow either " or ' as their string character.

giveHtml (Leaf (a,(b,c))) = "<frame src='' name='" ++ [a] ++ "' scrolling='No' noresize='noresize' id='" ++ [a] ++ "' title='" ++ [a] ++ "' />"

Less escape characters all round :) You can even (if you wish) write a singleToDouble function that replaced all ' with ", but its not necessary when generating HTML. Thanks Neil
