Good concept but doesn't work. Example, type different variations of legal well formatted addresses. 1 Microsoft Way Apt 43, Redmond, WA 98065, U.S.A. 1-1/4 Palm Hwy, Colino, MA 87009, USA 500 Potasium Cloride, Sunshite-Big Blow City, PA 30000, United States of America First line output should look like: 1 Redmond 98065 U.S.A. Also having country-specific obscure sports terminology on landing page example can cause l…

Sketching is a superset of programming by example. In examples, you only get input/output pairs, which as this thread shows, infers frustratingly close but wrong programs. In sketching, the input and output can also includes partial programs (sketches), so you can mark what you like, tweak, etc, and it fills in the rest. Increasing usability, the fragments can be in different languages. For example, input can be simp…

Cool. I have been mulling what it would be like to have a semigraphical tool to generate SQL queries (Spark,Hive,VoltDB,etc) where the user would drive a keyboard applying operators over columns, rows and relations for mapping, filtering, joining. Like VIM plus ZPL and the goal is a statistical result over some range. Why can't prolog programs generate our programs? One of my query visualizations is an origami like s…

  In:
  3, Roberto Carlos, soccer, Brazil
  35, Michael Jordan, baseball, USA
  6, James Dean Lebron, basketball, USA
  10, Shinji Kagawa, soccer, Japan

  Ex: Carlos is number 3 playing soccer

  Out:
  Carlos is number 3 playing soccer
  Jordan is number 35 playing baseball
  Dean is number 6 playing Lebron (what??)
  Kagawa is number 10 playing soccer

Great tool, but too bad it can't handle code very well. An example (converting C++ to C): Input: void FileStream::write(char* , int); void VirtualMachine::cycle(int); Example: void FileStream_write(char* , int); Output: void FileStream_write(char* , int); void VirtualMachine_cycle(int* , ); Also, is it open-source?

  @(repeat)
  @type @class::@ident(@params);
  @  (output)
  @type @{class}_@ident(@params);
  @  (end)
  @(end)

  !txr some_transform_script.txr -

  static val foo(val x, val y);

  reg_fun(intern(lit("foo"), user_package), func_n2(foo));

  @(deffilter sym ("_" "-"))
  @(collect)
  @  (cases)
  @/(static )?/val @fun(void);@(bind arg nil)
  @  (or)
  @/(static )?/val @fun(@(coll)@{type /[^ ,]+/} @{arg /[^ ,)]+/}@(until))@(end));
  @  (end)
  @(output)
    reg_fun(intern(lit("@{fun :filter sym}"), user_package), func_n@(length arg)(@fun));
  @(end)
  @(end)
