This time the plugin install worked perfectly and the GWT icons are now showing up correctly. To Run as Administrator, right-click on the Eclipse icon, select the Run as Administrator option.

Re: Native JSON and safe parsing implementation
Thanks for the reply and the source reference. I hadn't seen that
class...it would be nice to pull that method into (maybe) JsonUtils so
that it would be in the core and more visible.
The RFC and the json2.js code (here: http://www.json.org/json2.js )
were both written by Douglas Crockford. The main difference seems to
be that the json2 code has been updated since the RFC was written to
deal with how javacript handles certain unicode characters (which will
cause erroneous parsing without escaping them) and to speed up the
regex testing in older versions of IE and Safari. These are the first
and second stages, respectively, as reference in the code above and
in the json2 code, with more explanation there.
However, the more important difference is that if a browser can
natively parse the JSON string, the json2 code (and thus the class in
my OP) will default to the native implementation. Besides the obvious
speed advantage to doing the parsing in native code, there are some
other problems with pure-js parsing. Most of the points on this page
are still true: http://ejohn.org/blog/native-json-support-is-required/
Anyway, obviously all that doesn't invalidate the current
implementation. Mostly this seems like an interesting case where
deferred binding would be the usual approach, but the delineation of
browsers with native JSON support doesn't match the current way the
browser targets are defined, necessitating a different approach.
Is there anywhere else in the codebase where native features are
supported similarly? I can think of something like getElementByID, but
that was added so long ago its probably a pretty clear case when
native support can be used
Thanks again.

I realize this post is coming at the end of the day on friday, but
hopefully it will get a look =)
Going through the different JSON parsing implementations available for
GWT out there, almost all of them rely on a straight eval and note
that they should only be used for trusted code. The old JSONValue code
seems kind of quaint in light of JavaScriptObjects, and looking
through the trunk it looks like there's just a TODO in JsonUtils for
safe parsing.
Anyway, I don't have that much experience writing JSNI code, so I
wanted to run this small class past you all and see if this aligns
with GWT best practices, if I'm doing anything monumentally stupid, or
if I'm just plain missing something.
The following is a pretty basic adaptation of Douglas Crockford's
json2.js. When parse() is called, it checks to see if there is a
native JSON defined (which exists in the latest IE, Firefox, Chrome
and Safari) and simply uses that. If not, it defines a $wnd.JSON.parse
in javascript using the json2 code, which is then indistinguishable
from the native functionality in future calls (this tactic comes
straight from json2.js).
It lazily initializes the JSON object, as defining an entry point
doesn't seem like a big win, and adds a lot of support necessary to
make it happen. It also defines it on the $wnd object...scope still
occasionally confuses me in javascript, but it seemed to make more
sense to define it there than on window.
Any thoughts? Even drive by comments are useful if it gives me enough
to google. Thanks!
The code:
/**
* Evaluates a JSON string safely
*
* @param T The type of JavaScriptObject that should be returned
* @param jsonString The source JSON text
* @return The evaluated object
* @throws NullPointerException if codejsonString/code is
codenull/code
* @throws IllegalArgumentException if codejsonString/code is

Display is about the same as View, and Controller is like
Presenter. You inject the View to the Presenter through its

doing something like View.setPresenter(this);
There are benefits, but having the View know about the Presenter seems
odd.
You could have:
LoginPresenter.View interface:
String getName( );
String getPass( );
void setPresenter(Presenter p);
LoginView.Presenter interface:
tryToLogin( )
LoginPresenter implements LoginView.Presenter with something like:
// call a remote service with myView.getName( ) and myView.getPass
( )
// on callback, if the service agrees, initialize everything, show
the menu, etc.
LoginView implements LoginPresenter.View with something like:
// add a click handler to its login button
// which will call presenter.tryToLogin( )
The LoginPresenter constructor looks like
LoginPresenter(LoginView view ...and some other parameters...)
myView = view;
myView.setPresenter(this);
...
This way of implementing things doesn't require sending events from
the view to the presenter, or the presenter providing callbacks to the
view... but somehow looks weird to me... any thoughts on it?
I'd rather use the following, though I understand why the
LoginView.Presenter interface could help with mocking (it's easier to
mock the view then, because you don't have to mock HasClickHandlers
and eventually HandlerRegistration and ClickEvent):
LoginPresenter.View interface:
String.getName()
String getPass()
HasClickHandlers getSignInButton()
The LoginPresenter constructor looks like:

Re: Native JSON and safe parsing implementation
Great!
stringify seems like it would make things even messier, but I guess
(though I'd have to look) if JSON is natively supported then the
browser vendor also has e.g. Date.prototype.toJSON() defined as well.
I look forward to seeing your code! especially that last case.

Funny! I'm finishing a JsonUtils patch (was about to submit it this
night but finally chose to review it one more time, ensuring tests
pass, checkstyle, etc.) adding:
- JsonUtils.safeParse
- JsonUtils.stringify
- JsonUtils.isArray (equivalent of ECMAScript 5's Array.isArray)
- deferred binding implementations using either native support
(user.agent=ie8) or emulation (eval() for the parsing; user.agent=
{ie6,gecko,opera}), and a fallback to emulation when native support
isn't available (e.g. recent versions of Firefox, Chrome and Safari
have native support, but older versions do not, so we detect if native
JSON is supported –recent versions– and fallback to emulation
otherwise –older versions–; user.agent={gecko1_8,safari})
I'm using a similar code at work with no problem so far.
I'll ping when my patch is sent for review.

Re: JSNI method doesn't work in IE?
Well, if you use a flextable, you can add a clickhandler to the flextable,
and in the handler do something like
@Override
public void onClick(ClickEvent event)
{
FlexTable source = (FlexTable)event.getSource(); // if you can't
get to the original flextable
Cell cellForEvent = source.getCellForEvent(event);
int rowIndex = cellForEvent.getRowIndex();
}

Re: JSNI method doesn't work in IE?
Hi Ian,
I can actually suggest an acceptable solution here, based on
inheritance:
private static class MyFlexTable extends FlexTable implements
HasMouseOverHandlers, HasMouseOutHandlers {
public HandlerRegistration addMouseOverHandler(MouseOverHandler
handler) {
return addDomHandler(handler, MouseOverEvent.getType());
}
public HandlerRegistration addMouseOutHandler(MouseOutHandler
handler) {
return addDomHandler(handler, MouseOutEvent.getType());
}
public Cell getCellForNativeEvent(NativeEvent event) {
Element td = getEventTargetCell(Event.as(event));
if (td == null) {
return null;
}
Element tr = DOM.getParent(td);
Element body = DOM.getParent(tr);
int row = DOM.getChildIndex(body, tr);
int column = DOM.getChildIndex(tr, td);
return new MyCell(row, column);
}
private class MyCell extends Cell {
protected MyCell(int rowIndex, int cellIndex) {
super(rowIndex, cellIndex);
}
}
}
and you just use the getCellForNativeEvent instead of getCellForEvent.
(passing in event.getNativeEvent() as a parameter)
I've submitted an enhancement request on the GWT issue tracker:

Re: Displaying static content on gwt client
Thanks for the reply.
So it means that it is going to be a GET request from the client to
the server for the resource once the client will load on the browser.
I am thinking to place most of the design code [html] in the static
files with .html and place their contents into the panel's setHtml()
instead of writing GWT code for every thing. like for example I have a
panel in the top that contains anchors like Home, Support, News etc.
Instead of creating a Hyperlink object for each link and setting the
style element to format it, I am thinking to read this chunk of code
from a html file [now use RequestBuilder] and use the panels's setHtml
(String) to display it. The benefit I can see with this approach is
avoid compiling the code even for a small change and also it could be
easy to change in the future.
Am I thinking in the right direction?

usually goes on the home page.
Firstly I tried separating the static content into html files and
reading them using java.io.FileReader to set them on the Panel's
setHtml(). I realized that GWT SDK does not allow to use java.io.* on
the client side. The only way I have now is to place the static
content into hard-coded string values like
Panel panel = new Panel();
panel.setHtml(pNews/pp news news nes newsnsnwensd nsdnewes/
p);
I have got a lot of static content to display on the home page which
is quite annoying to place in the String. Is there any other way/
solution around.
thanks

Re: JSNI method doesn't work in IE?
It's also possible to extend FlexTable with a HasMouseOverHandlers,
HasMouseOutHandlers and HasMouseMoveHandlers, and copy what GWT does
for onClick. However, you will have to do a lot of manual labour in
onMouseMove.

Well, if you use a flextable, you can add a clickhandler to the flextable,
and in the handler do something like
@Override
public void onClick(ClickEvent event)
{
FlexTable source = (FlexTable)event.getSource(); // if you can't
get to the original flextable
Cell cellForEvent = source.getCellForEvent(event);
int rowIndex = cellForEvent.getRowIndex();

Ian, thanks for your reply.
I'm trying to dynamically create a table and attach a mouseover

widgets. Any idea how I can do this with GWT, given the current
situation with IE?

Re: how to send variables in form panel
So in any way you will send multipart message to the server. The multipart
message have same structure like normal message request. Have header and
body. The key difference is the body structure. The body contain more then
one message in his structure. Example:
MIME-Version: 1.0
Content-Type: multipart/mixed; boundary=frontier
This is a message with multiple parts in MIME format.
--frontier
Content-Type: text/plain
This is the body of the message.
--frontier
Content-Type: application/octet-stream
Content-Transfer-Encoding: base64
PGh0bWw+CiAgPGhlYWQ+CiAgPC9oZWFkPgogIDxib2R5PgogICAgPHA+VGhpcyBpcyB0aGUg
Ym9keSBvZiB0aGUgbWVzc2FnZS48L3A+CiAgPC9ib2R5Pgo8L2h0bWw+Cg==
--frontier--
So you need to parse this message to get the data out of the body. I post
you one example before how to parse multipart message. You can access the
parameters like this httpRequest.getParameter(warehouse). If its null
you probably don't send it correctly. Use firebug to see the traffic between
client and server.

yes, of course I put the multipart in client code:

I have a form with uploadfile widget, and some textbox.
the uploaded file was successfully sent to server,, but the textbox

is there any other way to uploadfile with some field (texboxes)?

Its probably a multipart message :S
Try googling for how to accept multipart message on the server side
here is some example but i don't know if you find usefull.
public HashMapString, InputStream parseMultipartMessage(
HttpServletRequest request) {
mapWithStreams = new HashMapString, InputStream();
boolean isMultipart =
ServletFileUpload.isMultipartContent(request);
try {
if (isMultipart) {
FileItemFactory factory = new DiskFileItemFactory();
ServletFileUpload upload = new ServletFileUpload(factory);
ListFileItem items = upload.parseRequest(request);
for (FileItem item : items) {
mapWithStreams.put(item.getFieldName(),
item.getInputStream());
}
} else {
mapWithStreams.put(DEFAULT_KEY, request.getInputStream());
}
} catch (FileUploadException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
return mapWithStreams;
In normal message (not multipart) data from the text fields come like
the body of the message. If you try to transfer file in normal message
then Stream is send like the body of the message. So you can transver
only Parameters or only stream. If you want to transfer parameters and
stream in same message you need to use multipart message. In multipart
message InputStream come on server like a body of the message. If that
input stream contain multipart message you need to parse that message.
So in one part you will have values from input fields and in other
part
you will have Stream for uploaded file. Read about multipart messages
on
the wiki site. Code abowe will parse all input streams from multipart
message and place them to the HasMap. The Key in HashMap is the File
name. You can access to streams later when you need them. To the
parameters you can access on the same way like you deed before:
request.getParameter(parameterName);
Good luck.

GWT.log listener in hosted mode
Hello, I am looking for some help. I want to be able to listen to the GWT.log messages that are output in the hosted mode console and use them in another application. Currently I am only interested in doing this locally. My thoughts are that the simplest way to achieve this is to some how write them to a file? Does anyone know how to do this? Ideally there would be a way that I can do this would modifying the GWT code base. Any help/ advice would be great.

Liferay and GWT integration issue
Hi, I'm trying to launch some hello world example using GWT and Liferay (Portlet container). I decided to use Liferay Bundled with Tomcat 6.0. Here are the details of solution I want to implement: 1. I'd like to attach code generated by GWT only once for the whole portal. I figured it out that I can include common js code which can be accessed by all portlets by creating portlet-ext.properties in which I can attach extra js files by editing property javascript.everything.files. I did so, newly created configuration file is being loaded and attached js code has been launched. 2. I deployed two independent portlets which can call simple JS functions implemented in previously attached file. Till now everything works fine and my next step is to attach gwt generated js file. I copy all files generated by gwt to directory in which there are all external js files, that is html/js. In my configuration file I add gwt bootstrap file called gwttestproject.nocache.js. Then when I reload application portal nothing special happens. I tried to manually run the function gwttestproject implemented in gwt bootstrap script and then whole page disappers. Probably it's because bootstrap script I've mentioned about uses document.write() method which causes whole document is being removed. I've read, but I don't remember exactly where, that in future version of GWT Google folks are going to change bootstrap script implentation to aviod this kind of problem. I downloaded GWT 2.0.0-ms2 but bootstrap didn't change. Anyway, if you have any experience with integrating Liferay and GWT, It would be great if you could drop here a line about your hacking :) Best regards, Janusz Prokulewicz --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

RunAsyncCallback
I'm trying to split my code using sort of proxies, where I reuse
parametrized RunAsyncCallback class. This class has basically just
reference to Gin Provider of the real module class. When I use this
for loading one module, it works perfectly, and I'm getting nice and
correct location of split point in report. When I use this second
time, loading different module proxy which uses the same
RunAsyncCallback class, both split points happen to be in Leftovers
code. Yet, split point on my proxies are still listed in report, but
with the same minimal (386) size.
I tried to use inline implementation of RunAsyncCallback instead, and
surprise! Split points worked correctly again.
Here is my parametrized RunAsyncCallback class:
class AsyncLoader implements RunAsyncCallback {
private ProjectPresenter parent;
private PlaceManager placeManager;
private Provider? extends AbstractLabeledPresenter real;
AsyncLoader( ProjectPresenter parent,
Provider? extends AbstractLabeledPresenter real,
PlaceManager placeManager ) {
this.placeManager = placeManager;
this.parent = parent;
this.real = real;
}
@Override
public void onFailure(Throwable reason) {
// TODO Auto-generated method stub
}
@Override
public void onSuccess() {
AbstractLabeledPresenter mod = real.get();
parent.addModule( mod );
if ( mod.hasToken( History.getToken() ) ) {
mod.revealDisplay();
parent.show(mod);
placeManager.fireCurrentPlace();
}
}
}
This is inner class defined in AbstractLabeledPresenter, that's the
same one I'm proxying and loading with GWT.runAsync. @Inject
annotation is not present because injection is done on proxy class
which in turn instatiates AbstractLabeledPresenter$AsyncLoader.
Not sure whether this is bug, but I can't see any linking or any other
rason why that code should end up in Leftovers and have empty, zero
size split points.

ListBox and listeners.
I have a issue that I'm trying to resolve and it may be something simple that I'm completely overlooking. I have a ListBox that has a ChangeHandler registered with it. I would like to programatically change the value of the ListBox and have an event fired that I can listen for. Unfortunately programatically changing the value does not fire an event to the ChangeHandler. While searching the internet I only came across disturbingly unelegant solutions to this problem (which I'm also convinced will not resolve the problem). I also have several TextBox objects that I can simply call setValue(some string, true) to fire an event to a ValueChangeHandler. The ListBox does not have a corresponding mechanism to fire an event. If anyone has any suggestions on how to tackle this problem, that would be greatly appreciated. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: ListBox and listeners.
The way I would do it is just to make a method out of what you call in your ListBox ChangeHandler then call that method anytime you set the value of the ListBox. Though depending on how complicated the page is or how many list boxes you have that could be a little tricky.

Re: JSNI method doesn't work in IE?
Hm. IE doesn't support setAttribute to set event listeners, and GWT
prides itself on not accommodating different browsers for things like
this,
You're best off writing your own.
Perhaps something like this?
public void onModuleLoad() {
final Label l = new Label(This is a label);
setProperty(l.getElement(),onclick, alert('hello'););
RootPanel.get().add(l);
}
private native void setProperty(Element e, String property, String
value) /*-{
var event = null;
value = event = function() { + value + };;
eval(value);
e[property] = event;
}-*/;

Re: RunAsyncCallback
Maybe somebody from google will confirm this, but I doubt you are going to
achieve code splitting by using proxies or interfaces, or by using any
generic parameterized approach.
A piece of code will end up in split-point-1.js *only if* it is always being
used from within GWT.runAsync(). If a class can be used from two separate
GWT.runAsync() method blocks, it is going to end up in the left-overs block.
Now here is my understanding of the situation (of course I may be wrong) -
- You have two instances of the class AsyncLoader, say LoaderA and
LoaderB, with two unique providers - say ProviderA and ProviderB
- GWTC recognizes that there will be two GWT.runAsync() blocks, which is
why it creates two split points
- But it cannot guarantee that LoaderA will always get ProviderA, and so
it should put the code for ProviderA in split-point1.js
- So, it knows that the entry point is not using ProviderA or ProviderB -
which is why it is not in the initial download fragment. But it cannot
guarantee it will always be used from a unique code fragment, which is why
it ends up in the left-over fragment.
- When you use the inline implementation, you will hard-code the actual
provider - and hence things will work.
The only pattern that works well is Googles recommended Async Package
Patter. See this
presentationhttp://dl.google.com/io/2009/pres/Th_1045_TheStoryofyourCompile-ReadingtheTeaLeavesoftheGWTCompilerforanOptimizedFuture.pdf.

Re: RunAsyncCallback
Also, this paragraph from Code Splitting
wikihttp://code.google.com/p/google-web-toolkit/wiki/CodeSplittingmay
be useful -
A less common example is that you expected an item to be exclusive to some
split point, but actually it's only included in leftover fragments. In this
case, browse to the item via the total program code subset. You will then
get a page describing where the code of that item ended up. If the item is
not exclusive to any split point, then you will be shown a list of all split
points. If you click on any of them, you will be shown a dependency chain
for the item that does not include the split point you selected. To get the
item exclusive to some split point, choose a split point, click on it, and
then break a link in the dependency chain that comes up.

GWT Maven2 (1.7.1) Possible?
I'm trying to get a first app up and running with GWT. What I would like to do is download the jars and compile with maven2. Has anyone been able to do this successfully? I can not find any documentation anywhere that actually leads me to a working example. Are the latest 1.7.1 jars available in any public maven repo? Is there any sort of commitment at all from Google to support Maven2? If anyone can help on getting GWT to compile/work with maven I will post the instructions for others in a readable format. If I'm the first to try and get this to run with Maven, let me know. thanks J.V. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

[gwt-contrib] Use native JSON when supported
Reviewers: Ray Ryan, bobv, Description: This patch adds: - JsonUtils.safeParse - JsonUtils.stringify - JsonUtils.isArray (equivalent of ECMAScript 5's Array.isArray) - deferred binding implementations using either native support or emulation (eval() for the parsing) ExternalTextResourcePrototype now uses JsonUtils.safeParse. This patch unfortunately introduces a circular dependency between c.g.g.core.Core and c.g.g.json.JSON to emulate JSON.stringify(); I believe JSONValues should use JsonUtils.stringify (adding overloads eventually) instead of JsonUtilsImplEmulated depending on JSONObject/JSONArray.toString, but it would require a major rewrite of the whole c.g.g.json.JSON module. I'm using a similar code (as an extension, not as a patch) at work with no problem so far. Please review this at http://gwt-code-reviews.appspot.com/86803 Affected files: user/src/com/google/gwt/core/Core.gwt.xml user/src/com/google/gwt/core/JsonUtils.gwt.xml user/src/com/google/gwt/core/client/JsonUtils.java user/src/com/google/gwt/core/client/impl/JsonUtilsImpl.java user/src/com/google/gwt/core/client/impl/JsonUtilsImplEmulated.java user/src/com/google/gwt/core/client/impl/JsonUtilsImplFallback.java user/src/com/google/gwt/core/client/impl/JsonUtilsImplNoArray.java user/src/com/google/gwt/resources/client/impl/ExternalTextResourcePrototype.java --~--~-~--~~~---~--~~ http://groups.google.com/group/Google-Web-Toolkit-Contributors -~--~~~~--~~--~--~---
[gwt-contrib] Re: Extending FocusWidget
Hi, thanks, that helped. I now check for both FocusWidget and HasState
On Oct 19, 10:31 pm, Thoka thobias.karls...@gmail.com wrote:
Hi,
Create an interface, like:
public interface HasState {
void setEnabled(boolean enabled);
boolean isEnabled();
}
...and then implement this with your composite widget. And don't try
to cast objects, GWT supports 'instanceof'. :-)
I hope this was to any help.
P.s. I'm actually confused that such an interface doesn't already
exist within the GWT API since many widgets have exactly those two
methods.

Hi all,
all the stuff that FocusWidget does is maybe too much for my case. I
only need to cast to something that has setEnabled(boolean) method. In
other words I want to create a widget that would act similar to
TextBox and similar input widgets. Then I want to checkout Widgets out
of my container, try to cast (FocusWidget), and if successful, call
setEnabled().
I tried to extend FocusWidget instead of Composite, but my widget
stopped working (event handler were not triggered) after that. Any
ideas how to overcome this?

[gwt-contrib] Comment on CodeSplitting in google-web-toolkit
Comment by a.revolution.ultra.blue:
One hack I was using to get modules to speak through compilations was
using Ray's exporter. Basically, common functions like custom dialogs that
cover the screen... If I want them to look nice, but be accessible before
I ever access Widget code, I use public static class methods like
note(String txt), ask(String question, AsyncCallback response, String ...
answers). These methods aren't even in the same package as the code that
implements them; they just tunnel through a JS API
$wnd.parent.MyExportedAPI. The root API module puts a JS object
MyExportedAPI on it's $wnd, then it loads the dll nocache.js files, which
implement things like note() and ask(), adding them to
MyExportedAPI.Dialog.ask()
Finally, each osgi iframe has .nocache.js modules that never access the
packages which implement the UI stuff, only static methods that tunnel to
$wnd.parent.ME_API {or $wnd.parent.parent...ME_API}. Biggest issue was
context. All callbacks from an osgi child of the root must send along it's
window variables {NOT $wnd}, and map all the parameters in and out of JSNI.
Think:
public static native void getFeeling(AsyncCallbackString callback)
/*-{
top.MyExportedAPI.ask(How are you, [Good,Great,Alright], {
wind: window
, callback : callba...@com...asynccallback::onSuccess(Ljava/lang/String;)
, err : callba...@com...asynccallback::onFailure(Ljava/lang/Throwable;)
});
}-*/;
then, to actually perform the callback, in JSNI,
x.callback.call(x.wind, 'Great')
PROBLEMS {only some of them}:
* Memory leaks; adding gwt workspace iframe.contentWindow to every tunneled
call could get REAL messy.
* Hand coded; it works, but there's piles and piles of boilerplate code;
external public static access, a to JSNI bridge method, a from JSNI bridge,
and finally, an implementation method. Don't forget @Export boilerplate
too!
* Tracing errors becomes nearly impossible. Had to make a special,
ForeignException so different frames could throw an error and call an
asyncCallback.onFailure without ClassCastException.
* Accessing osgi subframes {/ls, /dl} without being a child of the root
frame = not possible. Power users like to skip straight to the url w/
content, sans fancy multiple-module downloads.
* Dlls came in .cache.html, so they didn't block downloads of other code,
which I thought was an advantage, but with heavy caching situations, weird
page reload bugs happened when the root api changed, but the children did
not.
* Proxied calls were slow
* Event.addNativeEventListener does not work through iframes
* Compile times through the roof!!
* A giant wad of atrocities I've tried to block out.
Trust me, the amount of extra dancing and working you will have to do
for dll osgi-like modules will cost you more time than money can
replace. And what Ray mentioned before about RPC is that your obfuscated
Java objects CANNOT sanely be made translatable unless you RPC
encode/decode when tunneling to the root MyExportedAPI. This would mean an
encode/decode pair of overhead methods for every paramete or returned
object that's not a primitive or JSO.
I did all this before runAsync and GWT2.0 was compatible with Appengine,
and I TOTALLY ABANDONDED THIS METHOD. It hurt too much to implement.
Maybe if I was a generator wizard like Ray it wouldn't be so bad, but at
least my package segregation methods made the root API modules
transferable to runAsync without worry of external dependancy.
...If you feel like you wasted time reading these run on sentences of mine,
do yourself a favor, AND SPARE YOUR CODING TIME, COMPILING TIME AND
EXECUTION SPEED: *Monolithic* *Compile* *Is* *The* *Only* _efficient_
*Way* *To* *Obfuscate*, *Split* *And* *Link* *Independent* *Modules*. Any
other way means a translation layer and jumping through lots of unnecessary
hoops!
