I have tried to declare a regex as global resource but getting error as shown in attached image.
I just want to keep it in here instead of anywhere else.
Assuming a XAML namespace of sys for System:
xmlns:sys="clr-namespace:System;assembly=mscorlib"
Then:
<Application.Resources>
<ResourceDictionary>
<sys:String x:Key="EmailPattern">... some regex patterm ...</sys:String>
</ResourceDictionary>
</Application.Resources>
Usage:
if (Application.Current.Resources.TryGetValue("EmailPattern", out object regexPattern))
{
Console.WriteLine(regexPattern);
}

I'm trying to apply regex in something like this, in terraform.
variable "version" {
type = "string"
default = https://s3-us-east-1.amazonaws.com/bucket/folder/item-v1.2/item-item2-v1.2.gz
description = "version"
}
name = "${replace(var.version, "//", "")}"
I just need to replace everything and output only "v1.2" for the name, specifically from the item-v1.2 file path. I was thinking of doing something along the lines of
name = "${replace(var.version, "//", "")}"
wherein I replace everything but v1.2.
Any idea how to do it? Thank you in advance!
There are a couple of issues with your variable definition (e.g. wrong use of quotes, variable name "version" is reserved due to its special meaning inside module blocks, and so on) so I operate on the following:
variable "my_version" {
type = string
default = "https://s3-us-east-1.amazonaws.com/bucket/folder/item-v1.2/item-item2-v1.2.gz"
description = "version"
}
Then you can extract the version (or replace everything else except the version as requested) from the sub-folder path like this (this has been run and tested with terraform console):
$ terraform console
> var.my_version
"https://s3-us-east-1.amazonaws.com/bucket/folder/item-v1.2/item-item2-v1.2.gz"
> regex(".*-(.*)/.*.gz", var.my_version)[0]
"v1.2"
> replace(var.my_version, "/.*-(.*)/.*.gz/", "<before> $1 <after>")
"<before> v1.2 <after>"
why Route::currentRouteName() not working in laravel 5 inside a controller method , but when i provide '\' before class name works . I need to know the reason why adding back slash before class works in this scenario. May be it is some oops scenerio , which i don't know . Please guide
$name = \Route::currentRouteName();
You need to understand how PHP Namespaces works.
Route is not within the controller namespace hence you need to provide the full namespace to Route class for it to be loaded. Route is in root namespace hence you reference it with \Route just like you would do in directory structures.
Assuming your controller looks like this:
<?php namespace App\Http\Controller
class HomeController extends Controller{
public function index(){
//Doing this will throw a Not Found exception because route is
//not inside `App\Http\Controller` namespace
$name = Route::currentRouteName();
//However if you specify the correct namespace it works like so:
$name = \Route::currentRouteName();
}
}
You can read more about namespace here:
http://php.net/manual/en/language.namespaces.php
You can use
\Request::route()->getName()
or
\Route::getCurrentRoute()->getPath();
Does Ember have any template helper "get-value-with-key"
I found the below usage, but not sure what it does exactly ?
{{get-value-with-key item optionValuePath}}
There is an Ember Get Helper for HTMLBars.
You might have to install the Package "ember-get-helper" if you are on ember < 2.1.
{{get object key}}
Let's say you have the following object:
var obj = {
"key1": {
"subkey1": "hello world"
}
}
Using Ember 3.18, to access "hello world" from the template, you can do:
{{get obj 'key1.subkey1'}}
You can use the build-in get helper. See docs here: Ember Docs.
Usage example:
{{get object key}}
Note that the get helper will not be able to work on all JavaScript keys. For example, a key with a '.' will not work with the built-in get helper.
For example, if you have a valid JavaScript object like:
const example = {
'example.pdf': 'pdf_url'
}
// You can access this key normally via
example['example.pdf']
however, this will not work in the get helper
{{get this.example 'example.pdf'}}
One solution is to create a helper that can support the types of keys you need to support. For example, I made a helper that can work on keys with a '.' by including '.' in the key name which are escaped like with ''.
{{get this.example 'example\.pdf'}}
The ember twiddle can be found here: twiddle

I'm trying to create a dynamic product discount using values from a webservice.
I've searched some guides on the internet about this matter and I found that I needed to use checkout_cart_product_add_after and checkout_cart_update_items_after.
However, I followed some guides. Created my own module (which is visible in Magento back office: Configuration > Advanced > Modules) and a observer for this module. I didn't create anything more but it's not working. Since I can see the module in that menu, I believe the problem is on the observer/event call.
Here is the config.xml (which is inside app\code\local\namespace\MyModule\etc) for my module:
<?xml version="1.0" encoding="UTF-8"?>
<config>
<modules>
<namespace_MyModule>
<version>0.1.0</version>
</namespace_MyModule>
</modules>
<global>
<events>
<checkout_cart_product_add_after>
<observers>
<namespace_MyModule_Discount>
<class>MyModule/Observer</class>
<method>MyModulePriceChange</method>
</namespace_MyModule_Discount>
</observers>
</checkout_cart_product_add_after>
</events>
</global>
</config>
And this is my Observer (which is inside app\code\local\namespace\MyModule\Model) for my module:
<?php
class namespace_MyModule_Model_Observer
{
public function MyModulePriceChange(Varien_Event_Observer $obs)
{
// Get the quote item
$item = $obs->getQuoteItem();
// Ensure we have the parent item, if it has one
$item = ( $item->getParentItem() ? $item->getParentItem() : $item );
// Load the custom price
$price = $this->_getPriceByItem($item);
// Set the custom price
$item->setCustomPrice($price);
$item->setOriginalCustomPrice($price);
// Enable super mode on the product.
$item->getProduct()->setIsSuperMode(true);
}
protected function _getPriceByItem(Mage_Sales_Model_Quote_Item $item)
{
$price = 4;
//use $item to determine your custom price.
return $price;
}
}
?>
Also, is it possible do call soap client to use a webservice inside a observer?
I hope my question is clear, thank you in advance for helping.
I see some issues with your config.xml. First of all, use capitalized both company name and module name. namespace_MyModule will become your namespace.
You have to declare models under global section like this:
<models>
<mycompany_mymodule>
<class>Mycompany_Mymodule_Model</class>
</mycompany_mymodule>
</models>
This will tell magento you want to use mycompany_mymodule for models in your module, and class name of each module will start with Mycompany_Mymodule_Model.
Where Mycompany and Mymodule are respective to folders of your module: app/code/local/Mycompany/Mymodule.
The modules section of config.xml should also have this namespace (Mycompany_Mymodule), matching name of your file app/etc/modules and folder structure in app/code/local.
The observers then become the following (I added type, and changed class):
<observers>
<namespace_MyModule_Discount>
<type>singleton</type>
<class>mycompany_mymodule/Observer</class>
<method>MyModulePriceChange</method>
</namespace_MyModule_Discount>
</observers>
Then try to test your observer method by adding there some code like die("message").
You haven't declared the models tag in the config.xml file.
An observer is a model after all and magento will not know where to find it (that MyModule/Observer you reference). Below it's an example of declaring models tag:
<models>
<MyModule>
<class>Namespace_Modulename_Model</class>
</MyModule>
</models>
Yes, you can do soap api calls inside observer.
XML Name space issue revisited:
I am still not able to find a good solution to the problem that the findnode or findvalue does not work when we have xmlns has some value.
The moment I set manually xmlns="", it starts working. At least in my case. Now I need to automate this.
consider this
< root xmlns="something" >
--
---
< /root>
My recommended solution :
dynamically set the value to xmlns=""
and when the work is done automatically we can reset to the original value xmlns="something"
And this seems to be a working solution for my XMLs only but its stll manual.
I need to automate this:
How to do it 2 options:
using Perl regex, or
using proper LibXML setNamespace etc.
Please put your thought in this context.
You register the namespace. The point of XML is not having to kludge around with regexes!
Besides, it's easier: you create an XML::LibXML::XPathContext, register your namespaces, and use its find* calls with your chosen prefixes.
The following example is verbatim from a script of mine to list references in Visual Studio projects:
(...)
# namespace handling, see the XML::LibXML::Node documentation
my $xpc = new XML::LibXML::XPathContext;
$xpc->registerNs( 'msb',
'http://schemas.microsoft.com/developer/msbuild/2003' );
(...)
my $tree; eval { $tree = $parser->parse_file($projfile) };
(...)
my $root = $tree->getDocumentElement;
(...)
foreach my $attr ( find( '//msb:*/#Include', $root ) )
{
(...)
}
(...)
sub find { $xpc->find(#_)->get_nodelist; }
(...)
That's all it takes!
I only have one xmlns attribuite at the top of the XML once only so this works for me.
All I did was first to remove the namespace part i.e. remove the xmlns from my XML file.
NODE : for my $node ($conn->findnodes("//*[name()='root']")) {
my $att = $node->getAttribute('xmlns');
$node->setAttribute('xmlns', "");
last NODE;
}
using last just to make sure i come of the for loop in time.
And then once I am done with the XML parsing I will replace the
<root>
with
<root xmlns="something">
using simple Perl file operation or sed editor.
