The ckit Library is a C front end written in SML that translates C source code (after preprocessing) into abstract syntax represented as a set of SML datatypes. The ckit Library is distributed with SML/NJ. Due to differences between SML/NJ and MLton, this library will not work out-of-the box with MLton.

As of 20100402, MLton includes a port of the ckit Library synchronized with SML/NJ version 110.72.

Usage

• You can import the ckit Library into an MLB file with:

  MLB file	Description
  $(SML_LIB)/ckit-lib/ckit-lib.mlb

• If you are porting a project from SML/NJ's CompilationManager to MLton's ML Basis system using cm2mlb, note that the following map is included by default:

  $ckit-lib.cm/ckit-lib.cm   $(SML_LIB)/ckit-lib/ckit-lib.mlb
  

  This will automatically convert a $/ckit-lib.cm import in an input .cm file into a $(SML_LIB)/ckit-lib/ckit-lib.mlb import in the output .mlb file.

Details
