There's a draft RFC floating around to support this but it hasn't gotten much love... You can use INCLUDEs to do something similar:

Main mapfile:

LAYER
  NAME layer1
  CLASS
INCLUDE 'style1.map'
  END
END

LAYER
  NAME layer2
  CLASS
                INCLUDE 'style1.map'
  END
END

style1.map:

STYLE
  COLOR 0 0 0
  WIDTH 1
END

Ideally you'd be able to extend a base style which is what the RFC proposes. You can also do that with the INCLUDEs if you store just the style properties but not the block, eg.:

CLASS
  STYLE
    INCLUDE 'style1.map'
    COLOR 255 0 0 # override color
  END
END

and style1.map contains:

COLOR 0 0 0
WIDTH 1

Subject: [mapserver-users] refactoring STYLEs ?

Hi,

Is it possible to add a style definition (inside a mapfile or elsewhere ) so that it wouldn't be necessary to repeat it for each layer ?

For instance :

2 layers with the same display style

LAYER
  NAME layer1
  CLASS
STYLE
COLOR 0 0 0
WIDTH 1
END
  END
END

LAYER
  NAME layer2
  CLASS
STYLE
COLOR 0 0 0
WIDTH 1
END
  END
END

==>

STYLE 'style1'
STYLE
COLOR 0 0 0
WIDTH 1
END
END

LAYER
  NAME layer1
  CLASS
STYLE
'Style 1'
END
  END
END

LAYER
  NAME layer2
  CLASS
STYLE
'Style 1'
END
  END
END

Thanks & Regards

Clement
