The Weird and The Wonderful

   

The Weird and The Wonderful forum is a place to post Coding Horrors, Worst Practices, and the occasional flash of brilliance.

We all come across code that simply boggles the mind. Lazy kludges, embarrassing mistakes, horrid workarounds and developers just not quite getting it. And then somedays we come across - or write - the truly sublime.

Post your Best, your worst, and your most interesting. But please - no programming questions . This forum is purely for amusement and discussions on code snippets. All actual programming questions will be removed.

Yes, it is. There's a comment to that effect the *first* time I do it in the code.

I don't believe the results are cleaner. For starters, you should have seen the nested #ifdefs it took to do this.

Second, the preprocessor method of doing this suffered from a serious design difficiency.

You couldn't use multiple static "instances" of that to drive multiple buses, which is a problem when you have a device that runs more than one display, or even more than one SPI device (doesn't apply to the parallel code but in principle it could)

Everything defined in this code is inside a template, meaning the statics are one-per-instantiation and the arguments to the template are the pin assignments. Ergo, for each different collection of pins tied to a bus, you have a different set of statics to work with, meaning you can drive multiple displays.

I'd also argue this is cleaner because it's all typed, whereas the preprocessor macros are not. That matters for more than safety. These days it also means better intellisense/autocomplete, which means more productive mucking about with the source.
Real programmers use butterflies
