Dstep Versions Save

This is a new major version with a whole bunch of new features and bug fixes. The biggest features are support for translating some preprocessor directives like: #define for simple constants and function like macros. This release also adds support for a new platform, Windows.

Here's the full changelog:

New/Changed Features

• Support for simple defines (like #define FOO 1)
• Translation of defines to functions (like #define FOO(a, b) a + b)
• Support for preprocessor token-pasting operator (##)
• Support for translation of whole packages (--package CLI option)
• Support for translation of preprocessor constants in array sizes
• Support for global comments and comments inside structs and enums
• Detecting collisions of renamed tag-space names (struct name_t ...) with existing ones
• Special treatment of a comment before header guard
• Support for removing excessive newlines and keeping original spacing
• Basic unit tests were added
• Cucumber tests were replaced with D-based tests
• Statements are now translated in the original order as the input file
• Multiple input files can be processed at once
• Extend a functionality that automatically replaces aliases to basic types with their D equivalents
• Add a switch --reduce-aliases which disables/enables the above functionality
• Add a switch --alias-enum-members which enables generation of aliases for enum members in the global scope
• Add a switch --translate-macros which can disable the translation of C macro definitions
• Add the libclang bindings as a test case
• Add support for Microsoft Windows
• Run Windows tests on AppVeyor
• Handle complex floating-point types.
• Use the new alias syntax (alias Y = X) in the output
• Support for custom global attributes (e.g. nothrow, @nogc)
• Add support for building with LDC
• Bump the minimum requirement D compilers to their latest version
• Always test using the latest version of DMD and LDC, including beta and nightly builds
• Bump the minimum requirement of libclang to 7.0.0
• Automatically generate the libclang bindings using DStep
• Add a switch --rename-enum-members, which enables stripping of superfluous prefixes from enum members.
• Add a switch --normalize-modules, which enables changing the names of modules to the D conforming form.
• Add support for bit fields.

This tool requires libclang. Any version that is 3.1 or later and binary compatible with 3.1 should work. Either download the pre-compatible libraries from the LLVM site or use libclang shipping with your system or available from the system package manager. For more information see the readme.
