melange is used to generate C-FFI bindings to libraries with a C API by parsing C header files.

melange was originally part of Gwydion Dylan. It has been converted to work with Open Dylan and c-ffi.

Build

Be sure that you cloned this repository recursively or have otherwise initialized and updated the git submodules. This will not build without the submodules present.

dylan-compiler -build parsergen
_build/bin/parsergen melange-core/c-parse.input melange-core/c-parse.dylan
_build/bin/parsergen melange/int-parse.input melange/int-parse.dylan
dylan-compiler -build melange

You should be using Open Dylan 2012.1 or later.

Usage

The documentation for this tool is available at http://opendylan.org/documentation/melange/.

Tests

Tests can be run via make check or just running run.sh within the tests directory.

Adding new tests is done by:

• Create a new directory within tests whose name starts with test.. Directories that are not named appropriately won't be found by the test runner.
• Within the new test directory, create test.intr which includes a C header file and defines an interface appropriate to test the desired features.
• Within the new test directory, create expected.dylan which contains the Dylan that melange should generate from the test.intr.

You should avoid any platform-specific dependencies as much as possible within tests as the test runner assumes that all platforms will generate identical output.

See the existing tests for examples.
