problem with html-entities (partially solved) #12

Open alogic0 opened 6 years ago

alogic0 commented 6 years ago

Examle of html when generation crashes

<a>&#xe802;</a>

if we convert this by the following code

lucidFromHtml (Options False True) "template" "<a>&#xe802;</a>"

we get 

"template :: Html ()\ntemplate = do\n    a_ \"\59394\"\n"

Then we putStrLn it and get incorrect Haskell-code

template :: Html ()
template = do
    a_ ""

with an error from GHC, something like that

error:
    lexical error in string/character literal at character '\59394'

So, we loose the entity presentation and get incorrect code. Should we filter output to restore entities or, at least, escape such symbols?

84f53c6 partially solves this. Symbols now are escaped and code doesn't crash, but entities are still not preserved.

I'm looking for a way how to tell TagSoup to not convert hexadecimal entities into symbols.
