lens-process dependencies

Motivation

lens-process provides optics for the process package. These optics provide convenient lenses, traversals, and prisms, as well as classy variants for significant classifiable portions of the library for convenience. In addition, we provide some combinators for working with CreateProcess types. The intention of this package is to create a well-typed optical layer for process, reflecting the shape of certain types of commands at the type level.

Changes

Revision history for lens-process

0.3.0.0

Final design - this will not change unless System.Process significantly changes.

  • System.Process.Lens.CommandSpec is renamed to System.Process.Lens.CmdSpec to be more flush with the data names
  • documentation improvements all around
  • Type signatures of combinators inheriting, piping, handling and nostreaming have had their unnecessary constraints dropped
  • microlens-process is now in lockstep featurewise

0.2.0.0

The module formerly known as Internal.hs is now called ProcessHandler.hs

the CreateProcess optics have changed to avoid name clashes with System.IO (stdin, stderr, stdout), instead opting for the post-fixed underscore.

Added doctest suite.

0.1.0.0

Decided agains the internal module, narrowing scope

0.0.5.0

Expanded the zoo, better docs

0.0.4.0

Added ‘Internal’ module providing convenient handlers for the output of a createProcess call.

Added some spurious deps for future work on process

0.0.3.0

0.0.2.0

Widened bounds, fixed up some documentation, added few combinators

0.0.1.0

  • First version. Released on an unsuspecting world.
