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 20200718, MLton includes a port of the ckit Library synchronized with SML/NJ version 110.98.
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 Library $ckit-lib.cm $(SML_LIB)/ckit-lib $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
The following changes were made to the ckit Library, in addition to deriving the .mlb file from the .cm file:

-
ast/pp/pp-ast-ext-sig.sml (modified): Rewrote use of signature in local.
-
ast/type-util-sig.sml (modified): Rewrote use of signature in local.
-
parser/parse-tree-sig.sml (modified): Rewrote use of (sequential) withtype in signature.
