" Thanks to Ian Lynagh for thoughtful comments on initial versions and

" for the inspiration for writing this in the first place.

"
|

" This style guesses as to the type of markup used in a literate haskell
|
||||
" file and will highlight (La)TeX markup if it finds any
|
||||
" This behaviour can be overridden, both glabally and locally using
|
||||
" the lhs_markup variable or b:lhs_markup variable respectively.
|
||||
"
|
||||
" lhs_markup must be set to either tex or none to indicate that
|
||||
" you always want (La)TeX highlighting or no highlighting
|
||||
" must not be set to let the highlighting be guessed
|
||||
" b:lhs_markup must be set to eiterh tex or none to indicate that
|
||||
" you want (La)TeX highlighting or no highlighting for
|
||||
" this particular buffer
|
||||
" must not be set to let the highlighting be guessed

" 2004 February 20: Cleaned up the guessing and overriding a bit
|

" 2004 February 23: Cleaned up syntax highlighting for \begin{code} and
