Hello Caiiycuk
This may be because there might be some code wrapping the asm.js. I'll try
building UnityJS and get back to you. You currently have to run SFE
separately after all optimizations and it has not been integrated into

Hey guys
On 1.36.2, I've found a bug where Emscripten's JS optimizer seems to be
removing a local function within the __embind_register_enum function in
embind.js if built with -O3 optimization. This is the piece of code that's
being removed:
_embind_register_enum: function(

Hey guys
Embind doesn't seem to have implicit registrations for native C++ types
that are 64 bits (e.g. unsigned long long). Anyone else run into this? I
could call _embind_register_integer, but that ends up truncating the
maximum range of the type. Is there any known workaround for this?

Hey guys
I just ran into an issue where I was seeing unresolved externals when using
Emscripten to transpile my test c++ file to JS. After digging for a while,
I figured out that the order of includes of the .a files is important. For
example, if you have 2 static libraries foo.a and bar.a,
Hello all
You may have noticed a new feature on the incoming branch - a new pass
called Duplicate Function Elimination (or DFE) has been added to the
JavaScript optimizer. It's a bit computationally intensive and is hence not
enabled by default. In order to use it, you have to be building at
for
this purpose?

Hey guys
After updating my local fork of Emscripten to 1.35.17, I am seeing sporadic
runtime failures where Emscripten identifies certain STL functions as
missing:
Some examples of functions:

Another thing to note is that only optimized builds are showing this
behavior - we are not seeing this on debug (unoptimized) builds.

Just use Javascript's TypedArray support
(https://developer.mozilla.org/en-US/docs/Web/JavaScript/Typed_arrays) to
expose the underlying array (note that you'll have to ensure that the
memory is not reclaimed by keeping the vector saved off).
Here's a sample implementation of
At Tableau, we have had a similar problem where we wanted to reuse a set of
bindings to emit non JS code. We came up with a clean solution where we
modified embind.js to contain "hooks" for each embind function. This
ensures that you only have one set of bindings, reducing the risk of bugs.
To
, unless you really care about that
(that is, if the bug you are trying to fix actually relies on this), you
should be just fine.

Hey all
I'm using Emscripten to convert a decent sized C++ codebase to Javascript.
As part of this process, I'm finding that debugging the unoptimized

embind seems to have an issue with binding constructors for a class with

the problem.
I'm trying to get bindings for the copy constructor and a constructor for a

I was wondering if embind supports stack allocated C++ objects (rather than
heap allocated)? This is for things like:

}
where keyMap could be a custom collection implementation and
GetKeyValuePairs() would return a
I think - looking at the documentation on embind that the answer is to use
value_object (and value_array). Please let me know if this is wrong.
