I have an entity with the following annotation
#Assert\Callback(methods={"checkValidity"})
And the method, under a condition adds an error :
public function checkValidity(ExecutionContextInterface $context)
{
if ($this->getAmount() < $this->getMinimumAmount()) {
$context->buildViolation('app.forms.transfer.errors.amountLowerThanMinimum')
->atPath('amount')
->setParameter('%minimumAmount%', $this->getMinimumAmount())
->addViolation();
}
}
To make it work, I have to put theses lines in validator.en.yml
# line: foo
app:
forms:
transfer:
errors:
balanceTooLow: Your balance is too low to transfer %amount% to %application%
amountLowerThanMinimum: The application %application% required that you transfer a minimum of $%minimumAmount%
It works perfectly, but if I remove this first dummy line
# line: foo
It doesn't translate my error anymore.
After searching for an explanation during an entire hour, I still don't understand what could explain this strange behaviour. Any idea ?

I'm creating a program in Q#.
Problem
You are given two qubits in state |00⟩. Your task is to create the following state on them:
1/3–√(|00⟩+|01⟩+|10⟩)
You have to implement an operation which takes an array of 2 qubits as an input and has no output. The "output" of your solution is the state in which it left the input qubits.
Code
namespace Solution {
open Microsoft.Quantum.Primitive;
open Microsoft.Quantum.Canon;
open Microsoft.Quantum.Math;
open Microsoft.Quantum.Convert;
operation Solve (qs : Qubit[]) : Unit
{
body
{
Ry(ArcCos(Sqrt(2.0/3.0))*2.0,qs[0]);
(ControlledOnInt(0,H))([qs[0]],qs[1]);
}
}
}
But when I run it show me the following error.
Error
CSC : error CS5001: Program does not contain a static 'Main' method suitable for an entry point
[C:\Users\Pawar\Desktop\HK\codeforces\Q#\Solution\Solution.csproj]
So I tried to put EntryPoint() before the method declaration . Which shows me different error as
error QS6231: Invalid entry point. Values of type Qubit may not be used as arguments or return values to entry points. [C:\Users\Pawar\Desktop\HK\codeforces\Q#\Solution\Solution.csproj]
Please help me how to run it properly ?
thanks ✌️
In order to run a Q# program as an executable, you need to have an #EntryPoint() operation defined. You can read more in this excellent blog post: https://qsharp.community/blog/qsharp-entrypoint/.
Specifically, in your case, the error message indicates that Qubit[] is not a valid parameter to the main entry point of your program. Which makes sense, because it doesn't make sense to pass an array of qubits when executing a program from the command line. And also, your operation doesn't print anything or return any results, so you won't be able to see what it's doing.
You should probably create an #EntryPoint() wrapper operation that invokes your existing operation with the appropriate parameters, maybe prints some diagnostics, and then returns some result. In your case, you could perhaps do something like this (note the additional namespaces you need to open):
open Microsoft.Quantum.Diagnostics;
open Microsoft.Quantum.Measurement;
#EntryPoint()
operation SolveForTwoQubits() : Result[]
{
using (qubits = Qubit[2])
{
Solve(qubits); // invoke your existing Solve operation
DumpMachine(); // outputs the state of your qubits
let results = MultiM(qubits); // measure the qubits
ResetAll(qubits); // reset the qubits to the initial state
return results; // return the measured results
}
}
This will give some output that looks like:
# wave function for qubits with ids (least to most significant): 0;1
∣0❭: 0.577350 + 0.000000 i == ******* [ 0.333333 ] --- [ 0.00000 rad ]
∣1❭: 0.577350 + 0.000000 i == ******* [ 0.333333 ] --- [ 0.00000 rad ]
∣2❭: 0.577350 + 0.000000 i == ******* [ 0.333333 ] --- [ 0.00000 rad ]
∣3❭: 0.000000 + 0.000000 i == [ 0.000000 ]

I've just managed to get mutation testing working for the first time. My usual testing framework is Codeception but as of writing, it is not compatible with mutation testing (although I believe work is being done on it and it's not far off). I'm using PHPUnit and Infection, neither of which seem easy to work out how to use.
My test suite generated ten mutants. Nine were killed and one escaped. However, I don't know what part of the code or the tests needs to be improved to kill the final mutant.
How do you get information about what code allowed the mutant to escape?
I found in this blog what I couldn't find in Infection's documentation: the results are saved in infection.log.
The log file looks like this:
Escaped mutants:
================
1) <full-path-to-source-file>.php:7 [M] ProtectedVisibility
--- Original
+++ New
## ##
use stdClass;
trait HiddenValue
{
- protected function hidden_value($name = null, $value = null)
+ private function hidden_value($name = null, $value = null)
{
static $data = [];
$keys = array_map(function ($item) {
Timed Out mutants:
==================
Not Covered mutants:
====================
It says that the mutation changed the protected visibility to private and that no tests failed as a result. If this is important, I can now either change the code or write another test to cover this case.
Now that I've found this, I've searched on the Infection website for infection.log and found --show-mutations or -s which will output escaped mutants to the console while running.
I'm actually using the original Deus Ex game from the year 2000. I created a child class of "DeusEx.Flare" and called it "rflare" and saved it to my own package. I have successfully compiled it, and it works, but not the way I intended. I want to override the function "LifeSpan = 30" and give it "LifeSpan = 120". The problem is the documentation. There practically is none. And the documentation I can find generally is too confusing and does not give good enough examples for what I'm tryng to do. here is the code. I know I'm supposed to be using the "super" expression but I have exhausted all the ways I know how to use it. I simply cannot get it to work. However, I can get it to work if I dont' mind throwing both the normal flare (which goes out in 30 seconds) and my own flare, which only drops to the ground without a sound but will in fact last 120 seconds. So my code would end up throwing 2 flares. 1 normal flare that goes out in 30 sec. and the other that does last 120 but does not get thrown like the normal flare does.
here is the code from DeusEx.Flare script that I'm trying to change.
function LightFlare()
{
local Vector X, Y, Z, dropVect;
local Pawn P;
if (gen == None)
{
LifeSpan = 30;
}
}
My first attempt was to copy this and change it in my own package. It worked but again, it shot 2 flares, 1 normal and 1 that sorta worked. I want to do only one. So here is my attempt at correcting the code.
function LightFlare()
{
Super(Flare).LightFlare();
if (gen == None)
{
LifeSpan = 120;
}
}
All this does is spawn the normal flare, with no difference in the time it lasts. Can someone please help me?
I would suggest copying the LightFlare function in it's entirety from the parent class and not calling super. You don't want the original function to run, as that will mess with the lifetime variable.
For instance:
class RFlare extends Flare;
function LightFlare()
{
local Vector X, Y, Z, dropVect;
local Pawn P;
// Original function here, change lifetime when specified.
if (gen == None)
{
LifeSpan = 120;
}
}
defaultproperties
{
}
So this is a strange one. My code does a bunch a things that are hard to explain (but if necessary I´ll try to explain), but the following works:
var res = data.delete_if (function(key, value) { return key == "a"; })
but the following crashes:
data.delete_if (function(key, value) { return key == "a"; })
So, the fact that I do not save the result of the delete_if function crashes the browser with the following stack trace:
Error: test: B environment should proxy a Ruby hash. (MDArraySolTest): Java::JavaLang::IllegalStateException: Channel stream was closed before response has been received.
java.lang.reflect.Method.invoke(java/lang/reflect/Method.java:498) org.jruby.javasupport.JavaMethod.invokeDirectWithExceptionHandling(org/jruby/javasupport/JavaMethod.java:453)
Any ideas of why this happens? Any solutions? I can provide more information if needed.
EDIT1:
Doing some more tests I found out that the error occurs only if the call to data.delete_if is the last statement on the script. If I add for example: console.log(""); after the call, everything works fine.
Thanks
Upon compiling, I am getting the following error:
C:\UDK\UDK-2010-03\Development\Src\FixIt\Classes\ZInteraction.uc(41) : Error, Unrecognized member 'OpenMenu' in class 'GameUISceneClient'
Line 41 is the following:
GetSceneClient().OpenMenu("ZInterface.ZNLGWindow");
But when I search for OpenMenu, I find that it is indeed defined in GameUISceneClient.uc of the UDK:
Line 1507: exec function OpenMenu( string MenuPath, optional int PlayerIndex=INDEX_NONE )
It looks like I have everything correct. So what's wrong? Why can't it find the OpenMenu function?
From the wiki page on Legacy:Exec Function:
Exec Functions are functions that a player or user can execute by typing its name in the console. Basically, they provide a way to define new console commands in UnrealScript code.
Okay, so OpenMenu has been converted to a console command. Great. But still, how do I execute it in code? The page doesn't say!
More searching revealed this odd documentation page, which contains the answer:
Now then, there is also a function
within class Console called 'bool
ConsoleCommand(coerce string s)'. to
call your exec'd function,
'myFunction' from code, you type:
* bool isFunctionThere; //optional
isFunctionThere = ConsoleCommand("myFunction myArgument");
So, I replaced my line with the following:
GetSceneClient().ConsoleCommand("OpenMenu ZInterface.ZNLGWindow");
Now this causes another error which I covered in my other question+answer a few minutes ago. But that's it!
Not sure if this is your intent, but if you are trying to create a UIScene based on an Archetype that has been created in the UI Editor, you want to do something like this:
UIScene openedScene;
UIScene mySceneArchetype;
mySceneArchetype = UIScene'Package.Scene';
GameSceneClient = class'UIRoot'.static.GetSceneClient();
//Open the Scene
if( GameSceneClient != none && MySceneArchetype != none )
{
GameSceneClient.OpenScene(mySceneArchetype,LocalPlayer(PlayerOwner.Player), openedScene);
}
