by Laurent Petit (and others)

Functions/macros variants of the ones that can be found in clojure.core 
(note to other contrib members: feel free to add to this lib)






Public Variables and Functions



  

  

  
-?>

  macro

  
Usage: (-?> x form)
       (-?> x form & forms)


  
Same as clojure.core/-> but returns nil as soon as the threaded value is nil itself (thus short-circuiting any pending computation).
Examples :
(-?> "foo" .toUpperCase (.substring 1)) returns "OO"
(-?> nil .toUpperCase (.substring 1)) returns nil


  
  
  


  

  

  
-?>>

  macro

  
Usage: (-?>> x form)
       (-?>> x form & forms)


  
Same as clojure.core/->> but returns nil as soon as the threaded value is nil itself (thus short-circuiting any pending computation).
Examples :
(-?>> (range 5) (map inc)) returns (1 2 3 4 5)
(-?>> [] seq (map inc)) returns nil


  
  
  


  

  

  
.?.

  macro

  
Usage: (.?. x form)
       (.?. x form & forms)


  
Same as clojure.core/.. but returns nil as soon as the threaded value is nil itself (thus short-circuiting any pending computation).
Examples :
(.?. "foo" .toUpperCase (.substring 1)) returns "OO"
(.?. nil .toUpperCase (.substring 1)) returns nil
