Could you please document what this change will allow you to do that you couldn't do before?

This change allows developers to add new JS built-in files without messing up with the wrapper files, since they are now automatically generated.

I can beef up the change log if that helps, at landing time or in a later version of the patch.

[Alex Christensen]

That's what I figured.
This patch seems good, but has way too much python for me to be an effective reviewer.

Put the "why" here.

Please use this method (copied from Source/JavaScriptCore/inspector/scripts/codegen/generator.py).

            text,
            '#endif // %s' % guard,

You can put it on the generator base class.

See above.

I would write this as a call to filter() since we don't need to extract anything from `object`.

I would rename this to --builtins-wrappers or just --wrappers.

Nit: bad indent.

This looks wrong. Shouldn't the argument be `v`?

Can we just omit generating clientData if it's not going to be used (presumably by staticGlobals)?

I think this should be m_vm to be consistent.

This should be in an #else .. #endif, right? You might want to bake that into the helper formatting function that wraps code in a guard.

> Source/WebCore/CMakeLists.txt:3747
> +    list(APPEND WebCore_Generated_Builtins ${DERIVED_SOURCES_WEBCORE_DIR}/${_objectName}Builtins.h)

I think the variable name style we try to stick to is to uppercase everything but the project prefix (I.e., WebCore).

Should the script itself be able to infer whether to perform the effect of --with-wrapper-files based on the target framework?

OK, I'll refactor that.

'v' is used but some bots may complain about vm being not used anywhere.

In real cases, clientData is used but in #if blocks.
Some bots may be compiling without all these #if blocks and will complain of clientData being not used.

In real generated code, we have several #if blocks.
We could add something like #if!ENABLE(...) && !ENABLE(...) but I am not sure this is with the effort.

I was not sure about whether adding an option or using the framework.
I went with the option to be consistent with the combined option.
But I don't really mind either way.

Patch is updated according comments.
I did not fixed some style comments for "empty classes" as the real code does not suffer from those.

I forgot to fix the option name but will do it. --wrappers is fine by me.

As for the copyright thing, I'll address it in another patch.

I think it's almost ready. Let's try to clean up code generation a little more.

(Applies throughout) Please put the expression to be wrapped into a string, like so. It is a lot easier to follow than using the overloaded + operator.

accessor_body = "%s& %s() { return %s; }" % (self.member_type(object), self.accessor_name(object), self.member_name(object))
lines.append(BuiltinsGenerator.wrap_with_guard(object.annotations.get('conditional'), accessor_body)

See above.

Please don't put newline literals in `lines`. I know its tedious but let's be consistent.

> +            lines.append(BuiltinsGenerator.wrap_with_guard(object.annotations.get('conditional'), "    " + self.member_name(object) + ".init(globalObject);"))

Same thing here, check len(self.internals).

> Source/JavaScriptCore/Scripts/builtins/builtins_generate_internals_wrapper_implementation.py:121
> +"""#define DECLARE_GLOBAL_STATIC(name)\\

Please extract this into a separate variable. In general we don't wrap function arguments to newlines in Python code.

> Source/JavaScriptCore/Scripts/builtins/builtins_generate_internals_wrapper_implementation.py:130
> +    UNUSED_PARAM(clientData);

I think you can check if not len(self.internals) > 0 here.

> Source/JavaScriptCore/Scripts/builtins/builtins_generate_internals_wrapper_implementation.py:137
> +            lines.append(BuiltinsGenerator.wrap_with_guard(object.annotations.get('conditional'), "        " + self.member_type(object) + " " + self.member_name(object) + ";"))

See comment above.

> Source/JavaScriptCore/Scripts/builtins/builtins_generate_wrapper_header.py:92
> +        lines = ["    explicit JSBuiltinFunctions(JSC::VM& v)", "        : m_vm(v)"]

Needs line wrap.

> Source/JavaScriptCore/Scripts/builtins/builtins_generate_wrapper_header.py:94
> +            lines.append(BuiltinsGenerator.wrap_with_guard(object.annotations.get('conditional'), "        , " + self.member_name(object) + "(&m_vm)"))

Same comments as above: extract the formatted string into a local.

> Source/JavaScriptCore/Scripts/builtins/builtins_generate_wrapper_implementation.py:41
> +        return self.model().framework.setting('namespace') + "JSBuiltins.cpp"

I would use format strings even for this. There are very few cases where using an overloaded + is more clear.

> Source/JavaScriptCore/Scripts/builtins/builtins_generate_wrapper_implementation.py:60
> +            header_includes.append((["WebCore"], ("WebCore", object.object_name + "Builtins.cpp")))

... I think this is an example of where it's ok: only one level of dereference, so it's not too big of an expression to see at once.

> Source/JavaScriptCore/Scripts/tests/builtins/expected/WebCore-ArbitraryConditionalGuard-Separate.js-result:236
> +    explicit JSBuiltinFunctions(JSC::VM& v)

Argument name should be 'vm'.

> Source/JavaScriptCore/Scripts/tests/builtins/expected/WebCore-ArbitraryConditionalGuard-Separate.js-result:399
> +    if (sizeof(staticGlobals))

I don't think this conditional is necessary. We can statically determine the length and add the following line or not. The same is true for clientData. In fact, maybe the generator for this method should have a separate code path if there are no internals, that just prints UNUSED_PARAM(globalObject). I don't think there is anything meaningful to do in initialize() if there are no internals.

> Source/JavaScriptCore/Scripts/tests/builtins/expected/WebCore-xmlCasingTest-Separate.js-result:501
> +#define DECLARE_GLOBAL_STATIC(name)\

Nit: should have one space between things and a trailing continuation '\'

> Source/JavaScriptCore/Scripts/tests/builtins/expected/WebCore-xmlCasingTest-Separate.js-result:509
> +          globalObject.addStaticGlobals(staticGlobals, WTF_ARRAY_LENGTH(staticGlobals));

This generated code can be cleaned up as noted above in the case where there are no builtins.

The issue here is not in the case where there is no internals.
The issue is that all internals may be guarded and guard being disabled.
In that case, compilers will issue warnings or errors because of unused parameters.

As I sad previously, we could wrap the UNUSED_PARAM in an "#if not any guard".
But I am not sure this is worth the effort.

This is the same principle as above.
I found it a bit better to have an if statement statically-resolvable, then an UNUSED_PARAM.
But I am fine using UNUSED_PARAM(globalObject) as is currently the case in the hand-written code.

I am not sure it is worth handling the no-builtin case.
In such case, the cpp file should not even be compiled.

Ah, ok, then I guess we might always need it.

No, that's too annoying. I agree.

I prefer an unconditional UNUSED_PARAM.

Ok.

Please address other comments and send through EWS again before landing.

Ossy, I plan to land this patch sometimes today.
Hopefully, it should not break any of your bots that disable all use of WebCore JS built-in internals (streams & webrtc).
Just in case, please let me know if you would prefer the landing to be postponed.

ALL EWS are green, so I can't see any blocker issue, feel free to land it. ;)
Don't worry about non default configurations, we can fix them later
if they had some problems.
