push/pop syntax indent (Read 2712 times)

Ira Full Member Offline Posts: 238 Dallas	push/pop syntax indent Oct 9^th, 2006, 7:09pm I was wondering (about 5 mins ago) if there would be some benefit to having the push/pop syntax indent (auto format) stuff between the 2 calls. I think it probably makes it easier to read the code. pushMatrix(); translate(100, 100); sphere(20); popMatrix(); ira

Ira Full Member Offline Posts: 238 Dallas	Re: push/pop syntax indent Reply #4 - Oct 11^th, 2006, 3:35pm my concern would be that new coders might get confused by the use of the block in this context-looks close to a function now. Rather than hacking auto-format, I was thinking more on the line of incorporating the indent as part of 1.0

I recommend this formatting:

Code:

pushMatrix();
translate(100, 100);
sphere(20);
popMatrix();

This is the spacing I've seen in all the OpenGL Programming books I've read. You can separate the levels by adding a line space before the pushMatrix() and after the popMatrix().

I would never show my students the { } additional syntax. It's not consistent with what they know about functions and blocks.

Sorry for digging up this old thread.

I've experimented with bracketing in matrix pushes, and the result is simply not a good way to go.

This is especially true if you ever needed to define a variable inside the block, then suddenly needed it after popMatrix(); What happens is the compiler will not find it, since the variable only existed in that block!

That is quite messy, as you can see..
