It is unlikely I will have time to figure out how to do code-flow analysis
any time soon, but maybe someone else will.

BTW, did you try using bracket syntax and/or string constants?

var json:Object = JSON.parse("{\"abcdefg\":1212121}");
alert(json['abcdefg']);

Or

const ABCDEFG:String = "abcdefg";
var json:Object = JSON.parse("{\"abcdefg\":1212121}");
alert(json[ABCDEFG]);

The latter will help you catch misspellings of the property name.

Well, sure, we could do some code-flow analysis.  But I don't know how to
do that and it wouldn't be a priority of mine at this time because I
haven't seen very many code examples where the JSON is a literal within
the application.  Most of Flex is client-server, IMO.  But we'll see what
others think.  And you are welcome to offer up a patch that does it.

Thanks,

thanks.
but i think the flexjs can get the name ,not from the json(server),
from the as code 

var json:Object = JSON.parse("{\"abcdefg\":1212121}");
alert(json.abcdefg);

the "alert(json.abcdefg);" code can get the "abcdefg" as var.

Re: flexjs eat json tilesets

2016-02-23 Thread Alex Harui 
The @expose/@export needs to be added before the final compiler
optimization pass.  Often the JSON is not explicitly included in the
source code since it often comes from a server request, so there is no way
to examine the source and know which properties to protect from renaming.
But you could certainly write a utility that examines a JSON structure and
generates a class definition for it.

You don't always want to protect the names of variables in an Object.

2016-02-23 Thread Alex Harui 
Some property names have already been "exported" by other classes which
means they won't be renamed.  There might already be a class with a
"children" property, for example.

Well, no, but having class definitions for your data is one of the
benefits of Flex/FlexJS and should save you time by making fewer mistakes
over time.

It might be interesting to see if you can build a utility program that
generates the class definitions from JSON output.

But you can also not use ADVANCED_OPTIMIZATIONS or use other tricks to
deal with renaming like in this post [1].

And there might be a way to cheat where you create a class definition with
every property name but not the exact structure of your data and use that
for some dummy variable in the app.

HTH,

I think in FlexJSStore.  The JSON data is supposed to be an array of
Product instances.  The inclusion of Product.as keeps its public
properties from being renamed.

Really, the uber-thought for FlexJS in general (with Advanced
Optimizations) is to not use un-typed references.  I still have on my
to-do list a compiler option that spits out a warning whenever something
resolves to one of a list of "untyped" types (Object, EventDispatcher,
IEventDispatcher).  I've been told that it is astounding how often we lose
the higher-level type via our APIs.  If you use event.target or
event.relatedObject, you've lost the higher-level type.

This is interesting.   Is there an example of this kind of pattern
somewhere in the FlexJS examples?

Hi Lizhi,

Your email did not format well, but IMO, you are seeing expected behavior
in the Google Closure Compiler optimization.  Unless you specify
otherwise, the GCC will rename variables, properties, etc.  Using straight
up JSON can be tricky in such situations.  You may have to specify and
even use a class definition for the JSON data structure.
