Comment 4 2015-03-06 15:18:42 PST

We do attempt to maintain the author formatting. If it is all on one line I think we will force it to break on multiple lines. That must be where the bug is.

Comment 5 2015-03-06 15:20:24 PST

From CSSStyleDeclarationTextEditor.js: // Pretty print the content if there are more properties than there are lines. // This could be an option exposed to the user; however, it is almost always // desired in this case. I think case the first property is an error and does not count, so we have 1 line and 1 property.

Regarding patch update: I added some more comments and fixed an issue where style declarations with already existing line-breaks were accidentally ignored.

Tobias Reiss

Comment 11 2015-03-10 08:26:11 PDT

I'm still not happy with my patch. What I really want to do is the following: - Listen on onLineChange and onPaste - Parse the line and add missing new line characters, colons and semi-colons. A parser should be able to convert: - key: value => key: value;\n - key; => key:;\n - /* key:value; key2:value2 */ => /* key: value; */\n/* key2: value2; */\n - key:value /* key: value; */ => key: value; /* key: value; */ Questions: - Where can I listen on "onLineChange" and "onPaste"? _reset doesn't seem to be the correct place. It's not called onLineChange. - Are you okay with the mentioned spec for the parser?

This comment applies to all comments in this patch. > Source/WebInspectorUI/UserInterface/Views/CSSStyleDeclarationTextEditor.js:218 > + _parseStyleDeclarations: function(string) The name _parse implies that you are parsing the string into some data structure / representation. Here you are just returning a formatted string, so perhaps this should be named _formatStyleDeclarations. The comment above the function shouldn't be needed with a clear name, but if you want to keep it can go inside the function. > Source/WebInspectorUI/UserInterface/Views/CSSStyleDeclarationTextEditor.js:230 > + style = mode.token(stream, state); Style: WebKit style for JavaScript is to just use var at the declaration point. You can move the `var`s from the for loop initializer section in front of the variables `stream` and `style`.

So the ';' that it finds could be in the middle of a string or comment: /* foo; bar */ div { background: url(some;thing); Likewise for the comment searching.

What I really want to do is the following: > > - Listen on onLineChange and onPaste > - Parse the line and add missing new line characters, colons and semi-colons. > > A parser should be able to convert: > - key: value => key: value;\n > - key; => key:;\n > - /* key:value; key2:value2 */ => /* key: value; */\n/* key2: value2; */\n > - key:value /* key: value; */ => key: value; /* key: value; */ That seems reasonable to me. I like the idea of splitting up the comments. > Questions: > - Where can I listen on "onLineChange" and "onPaste"? _reset doesn't seem to > be the correct place. It's not called onLineChange. I don't think CodeMirror has "onLineChange" it has more generic change events, which we have registered for: http://codemirror.net/doc/manual.html#events this._codeMirror.on("change", this._contentChanged.bind(this)); I don't remember off hand, but I would guess that pastes trigger a change as well.

Comment 14 2015-03-10 11:02:31 PDT

The goal of this change is to format the style sidebar, correct? If so, I wonder if we should do this for everything. We currently try to preserve the developer's formatting except for the case I mentioned in comment #5. I think we might want to improve the auto-completion to auto insert semicolons and newlines as you type and not try to clean up the existing code. That will be a much more attainable goal. Adding a parser / formatter is costly to the project and can be a performance bottleneck. Was the original code in the attached images from a page or typed in the Inspector via live editing?

Comment 15 2015-03-10 11:11:30 PDT

> I see the logic here, but because we are using a CSS tokenizer we should > take advantage of it. In case we do go down the parser route: There is a tool I use to see CodeMirror's tokenizer / parser output. Open up Source/WebInspectorUI/Tools/PrettyPrinting/index.html in your browser and play around with it. Switch the language to CSS, and write some code and you can see what CodeMirror's tokenizer/parser state looks like. For instance: div { /* comment */ color; color: red; } Outputs: Token: 'tag' Stack: 'undefined' Current: 'div' Token: null Stack: 'undefined' Current: ' ' Token: null Stack: 'rule' Current: '{' Token: null Stack: 'rule' Current: ' ' Token: 'comment' Stack: 'rule' Current: '/* comment */' Token: null Stack: 'rule' Current: ' ' Token: 'property' Stack: 'rule' Current: 'color' Token: null Stack: 'rule' Current: ';' Token: null Stack: 'rule' Current: ' ' Token: 'property' Stack: 'rule' Current: 'color' Token: 'operator' Stack: 'propertyValue' Current: ':' Token: null Stack: 'propertyValue' Current: ' ' Token: 'keyword' Stack: 'propertyValue' Current: 'red' Token: null Stack: 'rule' Current: ';' Token: null Stack: 'undefined' Current: '}' So it seems like using CodeMirror's CSS mode you should be able to detect comments and "property;" and "property: value" patterns rather easily without direct string searching. As for the cost, I have a feeling it is not very costly because CodeMirror is already parsing so that we can get syntax highlighting.

Comment 16 2015-03-10 11:22:02 PDT

One other reason I don't really like this, is it hides errors from the developer. Your patch is fixing up the code in the sidebar, but that bad CSS is still being applied to the page. If you click through the the CSS resource you will see the original bad code (or on the DOM node in the style attribute). Fixing errors as the developers pastes or types is fine, but papering over them after the CSS is already on the page is not okay and just hides the problem. We should consider using the existing CSS pretty printer and adding a pretty print toggle to the sidebar if we want to have a way to pretty up the code. But the pretty printer does not fix developer errors.

Comment 17 2015-03-24 02:11:15 PDT

Created attachment 249322 [details] Describes different behavior of details sidebar's pretty print As described in the video "_resetContent" handles pretty print differently depending on how many "visible" properties are available in one line. My questions now are: - Is this a bug? - Shall we pretty print invalid properties and comments or remove them? Timothy, you pointed out that we should only pretty print and not modify styles because the bad css is still available in the code, right? In that case I would consider this behavior being a bug.

My > questions now are: > > - Is this a bug? > - Shall we pretty print invalid properties and comments or remove them? Looks and sounds like a bug. As a user, I wouldn't expect content to suddenly be removed, even if it is invalid. > Timothy, you pointed out that we should only pretty print and not modify > styles because the bad css is still available in the code, right?

If you are one of those types, you shouldn't need to run the others. Likewise it gives an opportunity to provide comments describing the case. I don't actually know what "isPrefixedProperty" means.

It may not be a property, it may be part of the value. For example: border: solid blue -webkit-calc(1px); Would incorrectly put a newline before -webkit-calc. Instead of `lastContent !== ":"` you should check the parser's state. I think here you can check if the state is `prop` (state.state === "prop") to know where you are.
