data PreConvert Source
The Coffeescript language compiles down to Javascript. Previously we waited until the very end, at the rendering stage to perform this compilation. Lets call is a post-conversion This had the advantage that all Haskell values were inserted first: for example a value could be inserted that Coffeescript would compile into Javascript. While that is perhaps a safer approach, the advantage is not used in practice: it was that way mainly for ease of implementation. The down-side is the template must be compiled down to Javascript during every request. If instead we do a pre-conversion to compile down to Javascript, we only need to perform the compilation once. During the pre-conversion we first modify all Haskell insertions so that they will be ignored by the Coffeescript compiler (backticks). So %{var} is change to `%{var}` using the preEscapeBegin and preEscapeEnd. preEscapeIgnoreBalanced is used to not insert backtacks for variable already inside strings or backticks. coffeescript will happily ignore the interpolations, and backticks would not be treated as escaping in that context. preEscapeIgnoreLine was added to ignore comments (which in Coffeescript begin with a '#')
