] | Hi,
I have some builtin modules such as `gpio`, `i2c`, `spi`, etc and I want to know how to support ES6's `import from` like below:
```js
import {I2C} from 'i2c'
```
I had read https://jerryscript.net/ext-reference-module/ and tried `JERRYX_NATIVE_MODULE ` like below:
```c
static jerry_value_t i2c_module_on_resolve (void) {
return ...;
}
JERRYX_NATIVE_MODULE (i2c, i2c_module_on_resolve)
void main() {
...
i2c_register();
...
}
```
But `SyntaxError: Requested module not found. [<anonymous>:1:19]` error returned when try to use `import {I2C} from 'i2c'`.
Actually I already have my own module loader `require()`, so when user try to use `import` I want to call `require()` internally.
Any examples, advices or suggestions?
Thanks in advance.

"jerryscript-project",

] | Hello,
Is there a way to get error position (row, column) in code?
For example:
```
jerry_value t parsed_code = ...;
jerry_value_t result = jerry_run(parsed_code);
if (jerry_value_is_error(result)) {
// want to know the position where the error was originally raised
}
```
I'm developing JavaScript IDE to support JerryScript. In here, I want to show error position in the Code Editor directly.
Moreover, I'm using Babel and Webpack to support users can use latest ECMAScript standard and use `import`, `require()` for import third-party modules. The transpiled and bundled code is executed by JerryScript. If there was an error, I need to show the error position in the original code (not transpiled/bundled) using `source-map`.
P.S.) Here is the project I'm working: https://kameleon.io

###### Backtrace
Script Error: SyntaxError: Invalid regular expression. [line: 2, column: 15]
###### Description
When executing the above testcase, the expected output should be '11'. However, jerry throws a SyntaxError while other JS engines such as V8, SpiderMonkey, JavaScriptCore output “11”. I suspect that it’s a bug of jerry. | A suspected bug of jerry regex engine | https://api.github.com/repos/jerryscript-project/jerryscript/issues/3001/comments | 0 | 2019-08-01T09:36:36Z | 2019-10-03T07:28:00Z | https://github.com/jerryscript-project/jerryscript/issues/3001 | 475,578,343 | 3,001 |

```
./tools/build.py --clean --debug --compile-flag=-m32 \

### Testcase:
````
1. var foo = function () {
2. var reg1 = new RegExp("{");
3. print(reg1);
4. var reg2 = new RegExp("A{");
5. print(reg2);
6. }
7. foo();
````
### Command:
`./jerryscript/build/bin/jerry testcase.js`
### Result:
````
/{/
Exception backtrace:
0: testcase.js:4
1: testcase.js:7
Script Error: SyntaxError: invalid quantifier
````
### Description:
Why does jerry report an error on line 4 but not on line 2? Maybe, jerryscript should not throw an exception on line 4.

"jerryscript-project",

] | Hello,
If my understanding is correct, in the jerryscript implementation, if an error is thrown when resolving a promise, it will only be passed to the rejection handler (if there is one registered). If there is no promise rejection registered, the error is silently ignored. I am looking for a way to make that error return to the calling function, or some other way to signal it.
My approach was to change `ecma_reject_promise()` to take an additional out parameter telling whether the rejection was handled or not. `ecma_promise_trigger_reactions()` sets this parameter to `false` in case the reactions collection was empty from the start. Based on this, `ecma_promise_reject_handler()` will return an error for unhandled rejections.
This works for a snapshot that was loaded, with all the chained promises' reactions registered. In this situation, when a `.then()` handler executes, we can determine whether it has a subsequent `.catch()` rejection handler chained. If it doesn't, `ecma_reject_handler()` returns with an error as expected.
This doesn't work for direct function calls. For instance, a scenario like `foo().then()`, where `foo()` calls into a C implementation that returns a rejected promise immediately via `jerry_resolve_or_reject_promise()`. At this point, I noticed `ecma_promise_do_then()` wasn't called yet to register the handlers and schedule the reactions.
I would like opinions on this approach. Do you think the current jerry design allows to signal unhandled errors thrown during exceptions, or it's always up the the developer to chain a `.catch()` call for thrown errors?
Thank you! | Discussion: Report unhandled promise rejections | https://api.github.com/repos/jerryscript-project/jerryscript/issues/2931/comments | 8 | 2019-06-28T14:17:10Z | 2021-01-18T13:59:42Z | https://github.com/jerryscript-project/jerryscript/issues/2931 | 462,056,947 | 2,931 |

Wrap the code in a function, the code above took about 2 seconds.

//(function() {
console.log("Start Benchmark\n");

var st = new Date();
var k = 0;

}

var ct = (et- st);
console.log("Time:" + ct.toString() + " Count:" + k.toString() + "\n");
}
//})();
```
But if just executing the code in the second block above, it took 13 seconds to finish, its 6.5x slower than wrapping it into the function....

[
"jerryscript-project",
"jerryscript"
] | I am currently constructing the layout for a C++ wrapper. This one is meant to be as thin and light as possible, as it's only purpose is to support OO programming with Jerry. Mainly meant to make wrapping C++ classes just a little bit easier.
https://gist.github.com/IngwiePhoenix/238db8d1a7f8731c6be7c4d28f20357c
The idea is:
- Use local variables instead of pointers to automatically trigger destruction (which should release the underlying `jerry_value_t`).
- Simplify defining native functions (`Value (*jerry_cxx_handler_cb)(Context)`) to make the handler signatures just a little less verbose. This is achieved by wrapping the actual callback in a generic `jerry_value_t (*)(jerry_value_t, jerry_value_t, jerry_value_t*, jerry_value_t)` and assigning it as the native pointer in a function (setting the native pointer in an object).
- Allow quick conversion between the C++ types and C types (`operator jerry_value_t ();`) to allow using the regular C functions as expected.
- Mimic common methods - but only those that are _really_ needed.
- Use sub-classing and inheritance on a simple, non-diamond level, to allow other C++ types to derive from it (`class MyJerryVector: public JerryScript::Object, public MyVector`) so that going back and forth between native and scripted calls is easier.
- Try not to use templates. Templates are great, but can bring forth more confusion than clearance.
So far, I have tried to map out the basic types and their structure. I am going to create a few `inline` functions to allow JerryScript to have a better and more controlled way of dealing with the C++ wrappers (like returning a `JerryScript::Value` instead of a `jerry_value_t`). Also, I decided to create a very basic base class `Value`, which serves as the foundation for any other type.
What do you think of the structure and idea? Is there anything that I am missing?
My goal is to contribute this towards `jerry-ext` in the future, to allow a user to also use JerryScript in C++, if they like. The wrapper is meant to make a few things more OO-ish, but not to wrap the entire C API.
```c++
// For example:
use JerryScript::Object;
use JerryScript::Number;
use JerryScript::String;
Object o = Object::global();
o["foo"] = String("bar");
o["baz"] = Number(42);
```
Would be glad to hear your thoughts! :) | Discussion: Thin C++ wrapper (jerry_value_t, core functions) | https://api.github.com/repos/jerryscript-project/jerryscript/issues/2884/comments | 2 | 2019-05-22T13:45:56Z | 2020-05-26T13:53:10Z | https://github.com/jerryscript-project/jerryscript/issues/2884 | 447,146,744 | 2,884 |
[
"jerryscript-project",
"jerryscript"
] | This is more of a curios question in the way of it being "theoreticaly possible or not".
Basically, I was wondering if I could slightly improve JerryScript's performance by swapping out certain parts of it - like it's JSON parser with something like [simdjson](https://github.com/lemire/simdjson), it's string handling with [rapidstring](https://github.com/boyerjohn/rapidstring), RegExp with [re2](https://github.com/google/re2) and it's compiler and VM with [asmjit](https://github.com/asmjit/asmjit).
Would any of this be possible? I doubt that just re-implementing the API won't do, forking the entire project seems more likely for some of the things. But what is most interesting to me is improving JerryScript's performance by using a JIT instead of an interpreter.
What do you think of this? | Curios/Question: Exchanging implementations | https://api.github.com/repos/jerryscript-project/jerryscript/issues/2883/comments | 3 | 2019-05-22T12:52:20Z | 2019-06-28T15:05:51Z | https://github.com/jerryscript-project/jerryscript/issues/2883 | 447,118,661 | 2,883 |
[
"jerryscript-project",
"jerryscript"
] | As part of my project, I need to expose some C++ APIs to JerryScript. Now, the best way to actually do that is by being able to tag the native instance onto the object created. Imagine this class for example:
```c++
class Foo {
public:
Foo();
~Foo();
int someMethod();
};
```
Now, what I guess I have to do, is to create a `jerry_native_object_info_t`.
```c
void foo_free(void* ptr) {
Foo* foo_ptr = (Foo*)ptr;
delete foo_ptr; // trigger deallocation and deconstruction
}
jerry_object_native_info_t foo_info = {
.free_cb = foo_free
};
```
So far, so good. But from what I figured, I would do something like this:
```c
jerry_value_t obj = jerry_create_object();
Foo* foo_ptr = new Foo();
jerry_set_object_native_pointer(obj, (void*)foo_ptr, &foo_info);
```
And get this pointer in a method like this:
```c
void* ptr;
if(jerry_get_object_native_pointer(obj, &ptr, &foo_info)) {
Foo* foo_ptr = (void*)ptr;
}
```
So far, this bit I did understand. But what if I want to have the instance of `Foo` tagged on an instance object? Do I define that in an `Object.constructor`? Is it save that - even when I have multiple `Foo`s around, that only the instance tagged to the specific object will be sent to the `free_cb` once the GC decides to delete it? (And on a side note: how do I actually define a constructor in C?)
Also, can I tag any kind of pointer in? Take for instance: I am working on a C++ wrapper, and I would like to reduce this:
```c
static jerry_value_t
function(
const jerry_value_t func_value,
const jerry_value_t this_value,
const jerry_value_t *args_p,
const jerry_value_t args_cnt
);
```
Into this:
```c++
Value function(Context ctx);
```
The idea I had, was to use a generic wrapper object which would construct a function off something like the following, and just take the returned value and return it like usual:
```c++
typedef Value (*jerry_cxx_handler_t)(Context);
jerry_object_native_info_t dummy_info = {
.free_cb = NULL
};
static jerry_value_t
cxx_wrapper(
const jerry_value_t func_value,
const jerry_value_t this_value,
const jerry_value_t *args_p,
const jerry_value_t args_cnt
) {
void* ptr;
if(! jerry_get_object_native_pointer(func_value, &ptr, &dummy_info)) { /* handle error */ }
jerry_cxx_handler_t handler = (jerry_cxx_handler_t)ptr;
Context ctx(func_value, this_value, args_p, args_cnt);
Value cxx_rt = handler(ctx);
jerry_value_t rt = cxx_rt.raw();
return rt;
// ctx and cxx_rt should auto-destruct and release their copy of the value properly.
}
```
Now, what I am curios about is: When constructing the `jerry_value_t` with the native pointer set to a `jerry_cxx_handler_t`, is it ensured that only _this_ `func_value` has exactly _this_ function pointer assigned at any time?

[
"jerryscript-project",
"jerryscript"
] | I would like to suggest a set of useful macros, for the case that someone is building modules right into the host application versus loading them dynamicaly.
The idea behind a macro like `JERRYX_NATIVE_MODULE_EXTERN(module_name)` would be, that a developer may be curating a list of built-in modules, through which they may iterate within the initialization of a program:
```c
jerryx_native_module_t internal_modules[] = {
_foo_definition,
_bar_definition,
NULL
};
for(int i = 0; internal_modules[i] != NULL; i++) {
jerryx_native_module_register(internal_modules[i]);
}
```
Currently, the developer has to actually be aware of the definition of `JERRYX_NATIVE_MODULE(...)` in order to do this. Having a set of helper macros that simplify the usage of this method would be quite helpful therefore. The macros would simply help to get the names right; to retrive the on-resolve callback, or the respective register or unregister function, if required.
What do you think? :)

] | I am working on writing wrappers for the [rlutil](https://github.com/tapio/rlutil) library, and right now I am a bit lost on the way to convert `jerry_value_t`s into `char*`s.
```c
static jerry_value_t
rlutil_setConsoleTitle(
const jerry_value_t func_value,
const jerry_value_t this_value,
const jerry_value_t *arg_p,
const jerry_value_t arg_cnt
) {
if(arg_cnt != 1) {
// handle eerror
}
jerry_size_t len = jerry_get_string_size();
char str[len + 1];
jerry_string_to_char_buffer(arg_p[0], &str, len);
setConsoleTitle(str);
return jerry_create_undefined();
}
```
I haven't had a opportunity to test just yet - writing this in my break time :). But, is this the correct way of doing this, and is there possibly a better way?

By skimming the source files and the wiki as well as the project's page, I kept reading that it supports ECMAScript 5.1, however JerryScript is implemented in such a small source tree, that I wonder what it actually supports - and what not?
A small listing of what it does and does not do, would be very nice :)
Kind regards,

"jerryscript-project",

] | Hey!
For a project that I am working on, I need a scripting language that is familiar to developers - so I decided to go and try out JerryScript. But good lord, I had no idea... ^^;
I generated this command quickly by using the fish shell:
```fish
echo gcc (find jerry-core jerry-ext jerry-main jerry-port/default/include -type d -exec echo -n "-I{} " \;) (find jerry-core jerry-ext jerry-port -name "*.c" -exec echo -n "{} " \;) jerry-main/cli.c jerry-main/main-unix.c -o jerry | pbcopy
```
and manually appending the `-D` definition.
This command is **big** and I wonder: Why is JerryScript's structure so huge, and is there some kind of explanation on how to integrate JerryScript on one's own build system, what `-D`'s it accepts and such?
I will need to add JerryScript into my own build tool, hence I tried to reproduce a full compilation "by hand" to learn how it is being built. And well, I learned that - and I am surprised I did not exceed the maximum number of arguments... ;)
Kind regards,

] | *Hi all! In an effort to make sure we're fully getting the word out to OpenJS Foundation project communities about the collaborator summit, I'm posting the following message on main or admin repos:*
This year, the Node Collaborator summit is opening up to include and welcome all former JS Foundation projects. The Collaborator summit is a space where projects and working groups within projects have the dedicated time and space to get together and get work done. We will have project-specific meetings, cross-project meetings on issues like security and standards, and of course meetings to discuss new programs and patterns for the new CPC.
The event will be in Berlin on May 30-31st at the Courtyard Marriott City Center. It is free to register with the password 'collabsummit.' We are also inviting all projects/attendees to suggest meetings and sessions via our CFP - these are not conference talks, but rather collaborative conversations or meetings you would like to hold with your peers. We ask that you register in advance so that we can allocate meeting room space and resources, and so that we can publish where conversations are scheduled in the day or two leading up to the event.

] | Hi there,
as jerryscript already has support for Promises I was curious how much work it would be to support async/await. Currently I am looking into using generators but as generators seem to create relatively simple code I was wondering if this was achievable with a moderate amount of work.
Best regards,
Paul | async/await support | https://api.github.com/repos/jerryscript-project/jerryscript/issues/2815/comments | 6 | 2019-04-09T05:52:18Z | 2020-08-27T12:08:04Z | https://github.com/jerryscript-project/jerryscript/issues/2815 | 430,779,130 | 2,815 |
[
"jerryscript-project",
"jerryscript"
] | ## Context
As part of the new [OpenJS Foundation's bylaws](https://github.com/openjs-foundation/bootstrap/blob/master/artifacts/OpenJS-Foundation-Initial-Merged-Bylaws.pdf), the Cross Project Council (CPC) has been [chartered](https://github.com/openjs-foundation/bootstrap/tree/master/proposals/stage-2/CPC_CHARTER) to serve as the primary governing body for programs and regular support of Foundation projects. For example, it will be responsible for things like infrastructure, travel assistance, CoC support, accepting new projects into the foundation, and mentorship programs to name a few. It will also be responsible for electing board representative(s) to the OpenJS Foundation board of directors.
**Any interested person from our project communities can attend CPC meetings and volunteer to participate in tasks.** For most programs, the CPC is expected to operate on the consensus of OpenJS Foundation project members. Issues that require a vote - namely the election of Board representatives and accepting a new project - will be memorialized by a voting CPC membership comprised of up to 2 representatives from Impact level projects and 2 representatives from Growth and At-Large stages.
If you'd like more info/context on the governance of the OpenJS Foundation, please let me know or follow this repo. The main point I hope you take away is that the foundation is to be run by and for the projects, and to do that we need participants from the project community.
## Request
As an At Large stage project, JerryScript is encouraged to send representatives to participate in CPC meetings, to advise on programs and support that will be helpful to it, and to nominate someone from the project community to serve in a voting capacity.
We anticipate having our first 'official' CPC meeting on May 30 or 31 at the Collaborator Summit in Berlin (sidebar, you should come!). In the interim, we would love for project members to participate in the Bootstrap CPC meetings which are currently held on Mondays (watch [this repo](https://github.com/openjs-foundation/bootstrap/issues/150) for meeting details).
If this is not the correct forum to raise this, please let me know and I will close the issue and post it in the preferred channel. Note that I'm posting essentially the same message to all OpenJS Foundation project repos, because I want to get the word out and make sure we all have the same information.
your pal,
Jory

So i have copied the cmsis path header files into "./build/jerryscript/targets/mbedos5/mbed-os/targets/TARGET_NORDIC/TARGET_NRF5x/TARGET_SDK_14_2/device/" path and then the "core_cm4.h" file issue get resolved.

/tmp/cczdc53K.ltrans0.ltrans.o: In function `jerry_fatal':
/wrk/jerryscript/jerry-core/jrt/jrt-fatals.c:58: undefined reference to `jerry_port_fatal'
```
I'm using a modified copy of `targets/particle/Makefile.particle` to get this going:
* Updated `EXT_CFLAGS` to match Particle's firmware [v0.8.0-rc.27 makefile](https://github.com/particle-iot/device-os/blob/v0.8.0-rc.27/build/arm-tools.mk#L30-L51).
```
EXT_CFLAGS += -g3 -gdwarf-2 -Os -mcpu=cortex-m4 -mthumb -mabi=aapcs
EXT_CFLAGS += -mfloat-abi=hard -mfpu=fpv4-sp-d16 -flto
```
* Updated `PLATFORM`, added `ARM_CPU`, and removed `LDFLAGS`.
```
PARTICLE_BUILD_CONFIG = \
INCLUDE_DIRS=$(JERRYDIR)/jerry-core/include \
LIBS=jerry-core \
PLATFORM=argon \
LIB_DIRS=$(BUILD_DIR)/lib \
APPDIR=$(JERRYDIR)/targets/particle/source \
TARGET_FILE=jerry_main \
TARGET_DIR=$(BUILD_DIR) \
ARM_CPU=cortex-m4
```
* Updated jerrycore build options:
```
-DCMAKE_SYSTEM_PROCESSOR=cortex-m4

```
jerry_value_t return_value;
return_value = jerry_load_function_snapshot(snapshot, snapshot_size, 0, JERRY_SNAPSHOT_EXEC_ALLOW_STATIC);
// The current allocated heap increase 3984 bytes
jerry_release_value(return_value);
jerry_gc(JERRY_GC_SEVERITY_HIGH);
// The current allocated heap decrease 2224 bytes
return_value = jerry_load_function_snapshot(snapshot, snapshot_size, 0, JERRY_SNAPSHOT_EXEC_ALLOW_STATIC);
// The current allocated heap increase 2112 bytes
jerry_release_value(return_value);
jerry_gc(JERRY_GC_SEVERITY_HIGH);
// The current allocated heap decrease 2224 bytes
```
The issue was not happened if I use static snapshot instead of dynamic snapshot (the heap always increases and decreases by exactly 24 bytes). I just want to know where does this leak come from, and is there anyway to remove a loaded dynamic snapshot completely? | Question: How to remove dynamic function snapshot completely? | https://api.github.com/repos/jerryscript-project/jerryscript/issues/2749/comments | 8 | 2019-02-02T16:47:07Z | 2019-07-01T07:51:13Z | https://github.com/jerryscript-project/jerryscript/issues/2749 | 405,999,390 | 2,749 |
