113.43.00

• Adds a Let_syntax module to Incremental_intf.S. We've found things like this useful in a couple of different projects as a nice alternative to the mapN functions.

113.33.00

• Made it possible to use Incremental without invalidation -- i.e. a change in a the left-hand side of bind does not invalidate nodes created on the right-hand side.

  This is configurable via the argument to Incremental.Make_with_config, which now takes:

  val bind_lhs_change_should_invalidate_rhs : bool
  

  So, one can now build an Incremental without invalidation using:

  Incremental.Make_with_config (struct
    include Incremental.Config.Default ()
    let bind_lhs_change_should_invalidate_rhs = false
  end) ()
  

  Implementation

  The implementation is simple: When a bind rhs changes, instead of invalidate_nodes_created_on_rhs, we rescope_nodes_created_on_rhs, which moves the nodes up to the bind's parent.

  Testing

  Turned the unit tests into a functor parameterized on bind_lhs_change_should_invalidate_rhs, and run them with both true and false. Modified tests where necessary to skip tests of invalidity when bind_lhs_change_should_invalidate_rhs = false.

  Added a unit test of bind_lhs_change_should_invalidate_rhs = true that makes sure a node created on a bind rhs whose lhs subsequently changes continues to stabilize correctly.

• Splitted incremental into a part that can run in javascript, incremental_kernel, and the other one.

113.24.00

• Add README.org to Incremental.

• Added some type annotations based on comments by @def-lkb about lack of principality.

• Switched to ppx.
