| 7 | 1 " Vim syntax file |
| 2 " Language: Haskell with literate comments, Bird style, | |
| 3 " TeX style and plain text surrounding | |
| 4 " \begin{code} \end{code} blocks | |

| 2152 | 7 " Last Change: 2010 Apr 11 |
| 2034 | 8 " Version: 1.04 |
| 7 | 9 " |
| 10 " Thanks to Ian Lynagh for thoughtful comments on initial versions and | |
| 11 " for the inspiration for writing this in the first place. | |
| 12 " | |
| 13 " This style guesses as to the type of markup used in a literate haskell | |
| 14 " file and will highlight (La)TeX markup if it finds any | |
| 15 " This behaviour can be overridden, both glabally and locally using | |
| 16 " the lhs_markup variable or b:lhs_markup variable respectively. | |
| 17 " | |
| 18 " lhs_markup must be set to either tex or none to indicate that | |
| 19 " you always want (La)TeX highlighting or no highlighting | |
| 20 " must not be set to let the highlighting be guessed | |
| 21 " b:lhs_markup must be set to eiterh tex or none to indicate that | |
| 22 " you want (La)TeX highlighting or no highlighting for | |
| 23 " this particular buffer | |
| 24 " must not be set to let the highlighting be guessed | |
| 25 " | |
| 26 " | |
| 27 " 2004 February 18: New version, based on Ian Lynagh's TeX guessing | |
| 28 " lhaskell.vim, cweb.vim, tex.vim, sh.vim and fortran.vim | |
| 29 " 2004 February 20: Cleaned up the guessing and overriding a bit | |
| 30 " 2004 February 23: Cleaned up syntax highlighting for \begin{code} and | |
| 31 " \end{code}, added some clarification to the attributions | |
| 2034 | 32 " 2008 July 1: Removed % from guess list, as it totally breaks plain |
| 33 " text markup guessing | |
| 34 " 2009 April 29: Fixed highlighting breakage in TeX mode, | |
| 35 " thanks to Kalman Noel | |
