" 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

" Read the C syntax to start with
if version < 600
  source <sfile>:p:h/c.vim
else
  runtime! syntax/c.vim
endif

" Objective C extentions follow below
"
" NOTE: Objective C is abbreviated to ObjC/objc
" and uses *.h, *.m as file extensions!


" ObjC keywords, types, type qualifiers etc.
syn keyword objcStatement	self super _cmd
syn keyword objcType			id Class SEL IMP BOOL nil Nil
syn keyword objcTypeModifier bycopy in out inout oneway

" Match the ObjC #import directive (like C's #include)
syn region objcImported contained start=+"+  skip=+\\\\\|\\"+  end=+"+
syn match  objcImported contained "<[^>]*>"
syn match  objcImport  "^#\s*import\>\s*["<]" contains=objcImported

" Match the important ObjC directives
syn match  objcScopeDecl "@public\|@private\|@protected"
syn match  objcDirective	"@interface\|@implementation"
syn match  objcDirective	"@class\|@end\|@defs"
syn match  objcDirective	"@encode\|@protocol\|@selector"

" Match the ObjC method types
"
" NOTE: here I match only the indicators, this looks
" much nicer and reduces cluttering color highlightings.
" However, if you prefer full method declaration matching
" append .* at the end of the next two patterns!
"
syn match objcInstMethod  "^[\t\s]*-[\s]*"
syn match objcFactMethod  "^[\t\s]*+[\s]*"


" Define the default highlighting.
" For version 5.7 and earlier: only when not done already
" For version 5.8 and later: only when an item doesn't have highlighting yet
