Pragmas ignored in \iohatex{...}?

[fedeinthemix]

Hi,

I've written a custom function called includeSnippet with the following signature

includeSnippet :: FilePath -> Text -> LaTeXT IO Text

In my .htex file I include

\begin{haskellpragmas}
{-# LANGUAGE OverloadedStrings #-}
\end{haskellpragmas}

However, if I don't use pack for the second argument haskintex gives the following error:

$ haskintex -verbose -keep test_3.htex 
Info: memotree does not exist.
-> Using empty memotree.
Enabled flags: keep, verbose.

It seems that during evaluation of the \iohatex{...} expressions, pragmas are ignored.

You are right, pragmas do not affect evaluation of either \hatex{...} or \iohatex{...}. There is no trivial fix for this. What I can do is parse the pragmas and then pass them to the evaluation.
