The MFC COM and OLE stuff is much worse, but not as bad as the C stuff.Ĭ++ templates can't hold a candle to Common Lisp macros. It's much easier to use from C++ with templates, ala ATL (ActiveX Template Library), WFC (Windows Foundation Classes), etc. Have you ever looked at or used the COM macros for generating C++ vtable layouts? It's attrocious! Actually, I really like COM for what it is (I use XPCOM at work, since we use xulrunner to implement TomTom Home), but COM's C bindings are total crap. There's nothing worse than having several object systems, especially when some of them are slow, non-standard and difficult to work with. It takes a horribly long time for GTK to initialize, and it's not Python's fault, it's GObject's fault. It accounts for most of the time spent by OLPC Sugar python applications initializing. I also don't like GTK's 'yet another object system'. SWIG is a much more advanced, much easier to use tool.

It doesn't handle other languages, either. It's horribly complex, totally undocumented, and very brittle. Because member references don't have to explicitly go through 'this'.īut if you did that kind of a transformation on C code by hand, you would have to rewrite every function signature to take an explicit 'this' argument, and rewrite every variable or function reference to go through the 'this' pointer.Īctually, I really dislike GTK's Python binding mechanism. The one thing C++ is really great at, is taking a C program with global variables and global functions, and easily transforming it into a C++ class that encapsulates all the variables and functions, without disrupting every line of code. And that is simply far too much work to do, and would be extremely tedious and error prone. In order to modify a C program to use structures and function pointers instead of global variables, you have to meticulously modify almost every line of code. So it looks as if it's some kind of mutated version of SimCity Classic which dates back to the C64 version. EA reserves the right to review and approve any version of the game distributed under the name SimCity. OLPC SimCity will be shipped with the OLPC, and it has been run through EA's quality assurance process and reviewed for integrity.

Don Hopkins adapted SimCity to the OLPC, thanks to the support of John Gilmore. SimCity is a trademark of Electronic Arts. OLPC SimCity is based on the TCL/Tk version of SimCity.The contract to sell SimCity for Unix expired after ten years, so the TCL/Tk version was no longer commercially available. The TCL/Tk version of SimCity has been ported to various Unix and non-Unix platforms, including SunOS, Solaris, Irix, HP/UX, OSF/1, Quarterdeck Desqview/X, NDC X Terminals, Warp, and Linux. After Sun canceled NeWS, DUX Software contracted me to rewrite the HyperLook user interface in TCL/Tk for X11, and I developed a multi-player networked user interface using the X11 protocol.The user interface was written in PostScript, which ran on the NeWS window system on Sun workstations, and it supported multiple zoomable views, pie menus, annotating and printing maps, and many user interface improvements.

DUX Software contracted me (Don Hopkins) to port SimCity to Unix, and I developed 'SimCity HyperLook Edition', while working at the Turing Institute on HyperLook with Arthur van Hoff.

Maxis licensed the Macintosh SimCity source code to DUX software, to port to Unix.

The original version of SimCity was developed by Maxis on the C64, and ported to various platforms, including the Macintosh.
