• A synthesis of new capabilities in Synergy/DE version 9

  Posted on Tuesday October 6th, 2009 at 14:43 in oop, synergyde, fp, synthesis, synbool, synvar, synlet, synprogn, synls, synswap, synregex, synelapsed

  As I threatened in my last post, I’ve combined a lot of my Synergy/DE version 9 work into a single library, which I have named “synthesis”.  Why synthesis? It’s a synthesis of most of my explorations of what I can do with Synergy/DE...

• Lazy math added to Synergy/DE mappers

  Posted on Wednesday August 26th, 2009 at 14:11 in var, filtering, sorting, synergyde, fp, ls, arraylist, synls, functors, lazyevaluation

  I mentioned in my last post on my ls class for Synergy/DE that it would be nice to include the mathematical operators in my support for lazy evaluation of mapping functors.  If you don’t understand what that means, perhaps you should go read that ...

• Sort methods added to ls class for Synergy/DE

  Posted on Wednesday July 29th, 2009 at 13:54 in sort, benchmark, synergyde, fp, ls, quicksort, arraylist, lambdas, mergesort, naturalorder, synls, functors

  Synergy/DE provides two built-in sorting functions, neither of which are useful for in-memory objects.  That’s not too surprising, considering that objects are relatively new to Synergy/DE. The SORT statement performs a Tournament Sort, but it onl...

• Properties: just like public member variables, except when they aren’t

  Posted on Monday June 29th, 2009 at 15:34 in ruby, visual basic, .net, c#, properties, oop, vb, synergyde, fp, outparams

  Many object-oriented languages provide an abstraction called properties:  data members that belong to a class instance, but whose public interface controls how those members can be manipulated via accessor methods.  In languages like C#, VB.NET, an...

• Progn for Synergy/DE

  Posted on Sunday June 28th, 2009 at 18:09 in lisp, Macros, functional, synergyde, fp, progn, synprogn

  As we have seen, it’s often useful in Synergy/DE to do more than one thing in a single statement – especially when defining macros.  One way you can join multiple operations is with a Boolean operator: status = (operation1() && operation...

• Functional Let for Synergy/DE

  Posted on Thursday April 23rd, 2009 at 11:41 in lisp, c#, oop, Macros, let, functional, synergyde, fp, synlet

  Synergy/DE possesses a macro definition syntax that’s very similar to the #define syntax in C, but not quite as robust.  It doesn’t support macros that expand to multiple lines of code.  An individual parameter passed to a macro cannot be conti...

• Functional “if” for Synergy/DE

  Posted on Monday March 2nd, 2009 at 13:00 in c#, Macros, IF, functional, synergyde, fp, imperative, synfif

  Programmers who have used languages derived from C will be familiar with C’s ternary conditional operator:   test ? iftrue : iffalse   which tests test for truth and returns iftrue if it is true, or iffalse if it isn’t.  No such operat...
