[CLOSED] All source mixes quote styles

Brackets source code should consistently use double quotes for JS string literals and HTML attribute values. With one exception: if the code is inside a string literal (which already uses double quotes), use single quotes instead to avoid escaping.

The current codebase mostly follows these styles, but it's inconsistent in a few places.

Examples:

// JavaScript
var foo = "some text";
var htmlCode = "<div id='some-id' class='some-class'></div>";

<!-- HTML -->
<div id="some-id" class="some-class"></div>

---

original description: I'm not advocating for either, but perhaps a definitive decision to use either single or double throughout the entire code base would be beneficial for maintainability.

Per our style guide all JS code should be using double quotes: https://github.com/adobe/brackets/wiki/Brackets%20Coding%20Conventions

Reviewed - we should use double quotes everywhere - leave it unassigned for now.

Does this apply to nested quotes as well? For example, should the single quotes below be converted to escaped double quotes or left as they are?

$("<div style='position:fixed;left:-50px;width:50px;height:50px;overflow:auto;'><div style='width:100px;height:100px;'/></div>")

Same question for these:

this.$htmlContent.append('<div class="shadow top"/>')

As this isn't explicit in the style guide, I personally prefer leaving the first one as is and changing the formatting of the second to match the first, but let me know and I'll make it happen.

+1@jedverity

Although note that for HTML code in a real .html file, we do use double quotes -- so basically I think the proposal is that the outermost language in the file uses double quotes, while any language nested inside strings uses single quotes if possible.

FWIW, in the jQuery source and tests we use:

var html = "<div id='single-quotes-for-attributes'></div>";

Can we just use double quotes on the whole just to make everything look the same and clean?

@WesleMPennock: The proposal is to use double quotes everywhere, with just one exception: code nested inside a string literal. That seems more readable than using escaped double quotes. Compare:

var html = "<div id='some-id' class='some-class'></div>";
// vs.
var html = "<div id=\"some-id\" class=\"some-class\"></div>";

Does that seem fair to you, or are you saying you prefer the second form?

Oh I am sorry I misinterpreted the proposal, I prefer the first it is much more readable.

Ok, sounds like there's a pretty solid consensus then. I've updated the description at top, and I'll update the style guide to cover the nesting case too.

I've done this issue with the pull request here (https://github.com/adobe/brackets/pull/1211).

I don't know how to attach a pull request to an issue though.
