Bug 99439 – [CSS3] Parsing the property, text-align-last.

• Status: RESOLVED
• Resolution: FIXED
• Component: CSS

[Dongwoo Joshua Im (dwim)]

This is the first step to support "text-align-last" property in WebKit.
Implement to parse the property, 
and test that with 'getComputedStyle'.

Please don't copy and paste code without looking at what it is doing.

> Source/JavaScriptCore/ChangeLog:8
> +        Regarding the CSS specification below, text-align-last property is needed to be implemented in WebKit.

Not a very helpful comment, anything mandated by the spec for compliance should be implemented.

> Source/WebCore/ChangeLog:13
> +        * Configurations/FeatureDefines.xcconfig: Add disabled CSS3_TEXT_ALIGN_LAST flag.

I really don't think another flag for a *single* feature is going to cut. I would rather see that you repurpose the existing CSS3_TEXT_DECORATION to be the umbrella flag for all CSS3 Text features.

> Source/WebCore/css/CSSParser.cpp:1864
> +        // left || right || center || justify || start || end || auto

Let's copy this from the spec:

// auto | start | end | left | right | center | justify

|| has a different meaning from |, see CSS 2.1.

> Source/WebCore/css/CSSParser.cpp:1866
> +            || value->unit == CSSPrimitiveValue::CSS_STRING)

I don't think this is right to allow CSS_STRING here: the specification doesn't mention it nor do I see special treatment for that value anywhere else.

> Source/WebCore/css/StyleBuilder.cpp:1144
> +        if (primitiveValue->getIdent() != CSSValueWebkitMatchParent)
> +            styleResolver->style()->setTextAlignLast(*primitiveValue);

This is obviously from text-align and the spec never says you should expect match-parent.

> Source/WebCore/rendering/style/RenderStyle.h:264
> +#if ENABLE(CSS3_TEXT_ALIGN_LAST)
> +        unsigned m_textAlignLast : 4; // ETextAlignLast
> +#endif // CSS3_TEXT_ALIGN_LAST

I don't think it's fine to bloat this structure with a new property (on top of that you should have updated the bit count below): we have a StyleRareInheritedData that handles properties we don't expect to see much in the wild.

> Source/WebCore/rendering/style/RenderStyleConstants.h:332
>  enum ETextAlign {
>      LEFT, RIGHT, CENTER, JUSTIFY, WEBKIT_LEFT, WEBKIT_RIGHT, WEBKIT_CENTER, TASTART, TAEND,
> +#if ENABLE(CSS3_TEXT_ALIGN_LAST)
> +    TAAUTO
> +#endif // CSS3_TEXT_ALIGN_LAST

I don't really like that. text-align and text-align-last have slightly different arguments, yet you piggy-back on this enum which makes it very likely that a programming mistake allows an error to slip through. On top of that, you get the legacy values straight into your new property (WEBKIT_LEFT, ...) which doesn't make much sense.

All in all, it's probably better to have a separate enum. We can always merge the logic later if we see that the need support for the other modes.

> LayoutTests/ChangeLog:11
> +        * fast/css3-text-align-last/getComputedStyle/getComputedStyle-text-align-last-expected.txt: Added.

It's not OK to land the bad baseline because the bots don't run with the feature enabled. Just skip the whole fast/css3-text-align-last directory on all platforms pending enabling the flag (you can open a bug for that or just point at the meta bug).

> LayoutTests/fast/css3-text-align-last/getComputedStyle/script-tests/getComputedStyle-text-align-last.js:69
> +

This is an *inherited* property so I would expect a test for that. How about the extensions you have mistakenly allowed by copying and pasting from ' text-align'? You should now test that we *don't* support them.

> LayoutTests/platform/chromium/TestExpectations:201
> +# Chromium doesn't support the css3 text-align-last yet.
> +webkit.org/b/99439 fast/css3-text-align-last/getComputedStyle/getComputedStyle-text-align-last.html [ Missing ]

This entry doesn't make any sense: you have an expected file above. The test is failing because the feature is disabled on the EWS, it should be SKIPPED until enabled (on all platforms).

Thanks for the review, jchaffraix!

This is my first step into CSS world, so I don't really understand well yet.
So, I'm still study about CSS features and implementations.

Working for this patch will help me to understand little bit more about CSS, hopefully.

But, as you know, text decoration and text alignment are in different chapter in the spec, and it seems they are really different feature.

I don't think "CSS3_TEXT_DECORATION" can be a kind of comprehensive flag of text-align-last and text decoration.


How about this?

1. Let's make "CSS3_TEXT_ALIGNMENT", and we can implement 'text-align-last' and 'text-justify' under the new flag.

2. Or, Let's make "CSS3_TEXT", and let text-align-last and text decoration be in the flag.


What do you think?

This is the one I've most worried about.
I will make another enum, then use TALLEFT, TALRIGHT, TALSTART and so on.

Option 2, I should have requested a broader flag upfront instead of settling for CSS3_TEXT_DECORATION. Please do the rename in a separate bug and CC me.

Drive-by comment
Nit: m_textAlignLast seems to take only 7 values. Can it use 3bits instead of 4bits ? 
IMHO Its better to be conservative of the number of bits being used by an object as it might have significant effect for memory aligned classes.

Hmm.. I think 3 bits would be enough.

It will need another round but it is way better.

> Source/WebCore/css/StyleBuilder.cpp:1949
> +    setPropertyHandler(CSSPropertyWebkitTextAlignLast, ApplyPropertyTextAlignLast::createHandler());

I don't think a custom property handler is needed. You should get the same result with:

setPropertyHandler(CSSPropertyWebkitTextAlignLast, ApplyPropertyDefault<ETextAlignLast, &RenderStyle::textAlignLast, EBorderStyle, &RenderStyle::setTextAlignLast, ETextAlignLast, &RenderStyle::initialTextAlignLast>::createHandler()));

> Source/WebCore/rendering/style/RenderStyleConstants.h:351
> +    TALAUTO, TALSTART, TALEND, TALLEFT, TALRIGHT, TALCENTER, TALJUSTIFY

The old properties are using fully capitalized names but the new ones tend to use camel case. I would use camel case as it matches our usual style and probably s/TAL/TextAlignLast/ on all the properties above.

> LayoutTests/ChangeLog:14
> +        * fast/css3-text/css3-text-align-last/getComputedStyle/script-tests/getComputedStyle-text-align-last-inherited.js: Added.

Side comment: testing all the inherited value is fine, you only needed to test one to make sure the inheritance works as expected (which could have been folded in the other test).

> LayoutTests/fast/css3-text/css3-text-align-last/getComputedStyle/script-tests/getComputedStyle-text-align-last-inherited.js:10

Is this required?

> LayoutTests/fast/css3-text/css3-text-align-last/getComputedStyle/script-tests/getComputedStyle-text-align-last-inherited.js:17
> +debug("Value of ancester is 'start':");

s/ancester/ancestor/ (applies to each debug statement)

> LayoutTests/fast/css3-text/css3-text-align-last/getComputedStyle/script-tests/getComputedStyle-text-align-last-inherited.js:23
> +debug("Value of ancester is 'end':");

> +testComputedStyle("end", "end");

There is a pattern here, you should probably move all this repeated code in a testing function. Also it would be better to have spaces between each values in the output for readability.

> LayoutTests/fast/css3-text/css3-text-align-last/getComputedStyle/script-tests/getComputedStyle-text-align-last.js:15

Really not sure what the toString() is testing nor that it is useful information. I would just drop it.

Not a super super helpful description.

description("This test checks that -webkit-text-align-last parses properly the properties from CSS 3 Text."

You should probably just replace this with the right HTML markup.

Where do you test the initial value?

Where do you test an invalid value?

As an extra protection, I would test against -webkit-left, -webkit-right, -webkit-center, -webkit-match-parent.

Just some small additions to Julien's feedback. The text decoration tests do combine testElementStyle and testComputedStyle into a 'testValue' method you might consider using.

> LayoutTests/fast/css3-text/css3-text-align-last/getComputedStyle/script-tests/getComputedStyle-text-align-last-inherited.js:3
> +    shouldBe("window.getComputedStyle(ancestor).getPropertyCSSValue('-webkit-text-align-last').cssText",  "'" + a_value + "'");

Nit: An alternative is getPropertyValue if you are just looking for the string value.

> LayoutTests/fast/css3-text/css3-text-align-last/getComputedStyle/script-tests/getComputedStyle-text-align-last-inherited.js:7
> +description("Test to make sure inherited -webkit-text-align-last property returns values properly.")

Nit: You could rephrase this to emphasize that you're testing css inheritance: "Test to make sure the -webkit-text-align-last property is properly inherited".

> LayoutTests/fast/css3-text/css3-text-align-last/getComputedStyle/script-tests/getComputedStyle-text-align-last.js:26
> +testContainer.innerHTML = '<div id="test" dir="ltr">hello world</div>';
> +e = document.getElementById('test');

Does the 'dir' attribute affect the computed values for text-align-last? If not, I would recommend omitting it. The spec talks mostly about the 'direction' style property as opposed to the 'dir' html attribute, so you may need to test both when actually doing layout.

This is not proper camel-case. Please don't capitalize the last word as it doesn't match WebKit style.

This line is wrong. [Missing] is about missing expected files which you have here. It should be [ Skipped ] or nothing (they are equivalent). It should also be located with the other fast/css3-text entry like the other changes.
