But you’re right – it is by far the market leader, so I really should’ve mentioned it. And I rather like it. In fact, it’s so good, I’ve thrown my hat in the ring for the github recommendation contest

I just read this post too and I was going to say the same thing! There are flags built in to stop you doing this sort of thing. I like -Wall -Werror -Wextra -pedantic off the top of my head, there are at least 5 that should be a requirement for any project, I have a standard line of about 10 flags that I apply to all of my projects.

@ everyone:

I know if you are in bussiness or games programming you might not have a choice but to use Visual Studio, but at least compile under gcc once in a while, even if you don’t release with it, just to make sure that you are creating robust code. At my work place we have 3 automatic regression/build test machines that every hour checks out a copy of our code and tries to build the Visual Studio project and gcc project for Windows as well as the gcc project for Linux and Mac and then email us if anything fails to build. The best thing is that each developer doesn’t need to actually have a Windows, Linux and Mac machine to write cross platform code, he quickly gets an idea via email of what will not compile. It would be great in the future to also have a commit hook so that you can’t even commit if the code is not cross platform.

$ cat test.cpp struct Vec3 { float i1,i2,i3; Vec3(float toto); };

Vec3 v = (2,3,0); tom@tomdell:~ $ g++ -c -Wall test.cpp test.cpp:6: warning: left-hand operand of comma has no effect test.cpp:6: warning: right-hand operand of comma has no effect

Do you still have the full Harmonize code? The gem only has 2 files in it — neither of which are the contacts.rb file you talk about in the article? If you have it, I’ll gladly dump it up to github.

Thanks! Ted

pixel.a = someValue > 4.5 ? 1.0 : 0.5; pixel.a = someValue > 4.5 ? (someValue > 6.0 ? 1.0 : 0.7) : 0.5;

Good luck with your shaders ! I’ve found the Apple Documentation to be quite lacking, I’m still looking for a list of all available functions.

As for the comma operator, one use in Javascript :

function doStuffWithNode(node) { if (someInvalidCondition) return Warning(’invalid node’), null }

This would call the log code then return null. I really prefer that to opening up braces and using 4 lines to log then return.
