Bug 27499 – Coding style - Clarify some cases with spacing

• Component: WebKit Website
• Status: RESOLVED FIXED

[Luciano Wolf]

Clarify the case where there is spacing before a comma/semicolon in a control condition and in functions.

I would like for it to be clear if the following is wrong or right according to the coding style.

for (int i = 0 ; i < 10 ; i++)
    doSomething();


// Qt's foreach
foreach (QString &item , items)
    doSomething();

f(a , b);

Personally I would vote for this being discouraged by the coding style, and I have personally yet to find such code in the webkit project.

What is your guys take on this?

[David Levin]

Putting no spaces before ; and , is basically following the current project style even though it isn't in the style guide.  I would likely mention it in a review.

[Kenneth Rohde Christiansen]

So you think it would be OK to make a patch for the coding style guidelines? If so, I can do that.

[David Levin]

Maybe just ask if this the current style on webkit-dev before and mention that you're willing to creating a style guide patch.

That's how I saw it happen when someone else added something to the guide.  This way everyone has a chance to see the style guide change. (They may not see the patch being submitted).

[Kenneth Rohde Christiansen]

I agree and have send an e-mail to the discussion list.

[Kenneth Rohde Christiansen]

From the mailing list:

I believe it is quite well established that a space should not be allowed before a ; or , in such circumstances.  (I have r-ed for it even ;) ).  I think we should definitely explicitly call this out in the guidelines if it is not already.

-Sam

The examples in the coding style guidelines use the right style (i.e. no space before the comma or semicolon), it would be fine to make it an explicit rule.

Patch coming up!

Add explicit rule about no space before comma or semicolon

Please take out the foreach examples as that's likely to confuse people not familiar with Qt :)  Otherwise, r+ following discussions on webkit-dev.
