" Vim syntax file
" Language: Scheme (R5RS + some R6RS extras)
" Last Change: 2012 May 13
" Maintainer: Sergey Khorev <sergey.khorev@gmail.com>
" Original author: Dirk van Deun <dirk@igwe.vub.ac.be>
" This script incorrectly recognizes some junk input as numerals:
" parsing the complete system of Scheme numerals using the pattern
" language is practically impossible: I did a lax approximation.
" MzScheme extensions can be activated with setting is_mzscheme variable
" Suggestions and bug reports are solicited by the author.
" Initializing:
" For version 5.x: Clear all syntax items
" For version 6.x: Quit when a syntax file was already loaded
if version < 600
syntax clear
elseif exists("b:current_syntax")
finish
endif
