SWIG has D support. But it seems old and out of fashion. Community here does not buzz about it much either. Whats the word on the street about the quality of SWIG-D stuff?

The swig bindings are good and I use them quite a bit to interface with legacy C++ projects.

This might be fixed already, I don't know and haven't tracked it but I had to make a minor change to the binding generator, as shown below.

edit commoncore_im.d and change the following:
---
mixin template SwigOperatorDefinitions() {
...
      static if (is(typeof(swigOpEquals(rhs)))) {
        return swigOpEquals(rhs);
      } else {
...
---
to
---
mixin template SwigOperatorDefinitions() {
...
      static if (is(typeof(swigOpEquals(rhs)))) {
        return cast(bool)(swigOpEquals(rhs)); // <-- cast(bool) added
      } else {
...
---

cheers, uri

I've used it quite a bit for a number of bindings (opencv, sfml + many other libs). It's much easier than the conventional approach of manual bindings (eg deimos), especially to keep the port up to date with upstream changes.

However the following should be worked on:

* support for newly introduced C++ namespaces (
https://github.com/swig/swig/issues/213)

* some support for multiple inheritance (I proposed using alias this in https://github.com/swig/swig/issues/98)

* mapping of C++ templates to D templates in simple cases at least (the templates would have to be instantiated somewhere in source file of course to avoid linker errors). Only the function signature would be mapped, the implementation would be still on C++ side

* miscellaneous compiler warnings that shouldn't be hard to deal with
  - Deprecation: Read-modify-write operations are not allowed for shared
variables : has a pull request (https://github.com/swig/swig/issues/203 )
  - missing override

* it would help to have a dedicated bug tracker for D-swig. Currently github issues for swig lump all other languages together, making D-swig of limited visibility for D community. At least create a SWIG-D label in github issues.

@klickverbot will tell you more as he implemented most of it IIRC

Actually I would like to try some stuff with opencv, but I've never used SWIG, so I don't know how hight is the bar.

To lower it, what do you think about some sort of github repo to push some  SWIG bindings into? Something like 'opencv/2.4.9/stuffinside'?
