Adding rules efficiently - google-chrome-extension

In background.js I am using rules but I am also using regex so many times. I have declarativeContent.ShowPageAction based on these rules.
new chrome.declarativeContent.PageStateMatcher({pageUrl: { urlMatches: 'https?:\/\/([a-z0-9]+[.])*microsoft.com'},}),
new chrome.declarativeContent.PageStateMatcher({pageUrl: { urlMatches: 'https?:\/\/([a-z0-9]+[.])*google.com'},}),
new chrome.declarativeContent.PageStateMatcher({pageUrl: { urlMatches: 'https?:\/\/([a-z0-9]+[.])*amazon.com'},}),
Is there a way to use regex only once and use it as in javascript
myRegexInstance.test(collectionOfURLs);

Don't use regexp. They're slow and you're duplicating the job already performed by the API: it already separated the URL into parts which you can test separately.
Use hostSuffix:
[
'.microsoft.com',
'.google.com',
'.amazon.com',
].map(s => new chrome.declarativeContent.PageStateMatcher({pageUrl: {hostSuffix: s}}))
The leading dot will match both *://google.com/ and any subdomain e.g. *://www.google.com/

Prestashop Friendly URL's

I've been trying to create a second option of url rewrites to a product inside prestashop. In the standard Prestashop installation at the SEO & URL's section i've got the following products url build-up:
{category:/}{id}-{rewrite}-{ean13}.html
This creates the following products url:
https://www.example.com/{category-name}/{product-id}/{product-name}/{ean13}.html
What i would like to add is an option for various reasons to acces a products page through the following url build up:
ean/{ean13}.html
The result url would be something like the following example:
https://www.example.com/ean13/{ean13}.html
NOTE, ID is a standard required field of the url build up, this means that i can't use: "Just ajust the url build up" as an answer.
Is there a module, addon, or piece of code out there that would be able to generate these kind of structures?
I did find some "Remove ID's from pretty url's" modules but that doesn't give me the result i'm searching for. Only partially since it only removes the ID's.
It wouldn't be a problem if it's a redirect to the standard url build up as mentioned in the first {code} segment. I know i could write rewrite rules in my .htacces file but to do this for every product would be a lot of work so i was wondering if there is a more easy way of achieving this.
As always thanks in advance!
If you're fine with redirect to standard URL then the solution is quite easy with a module.
Create a module that uses hook moduleRoutes and configure a friendly URL to use module controller
Create a module front controller
Run a db query in your custom controller to check if a product with requested EAN exists
Redirect to product page if product exists, otherwise to 404 page or something
I assume you know how to write modules and controllers, so I won't write entire code just the relevant bits.
Hook moduleRoutes in module class.
In this hook you can configure a friendly URL for your custom controller.
public function hookModuleRoutes()
{
return [
'mymodulename-mycontrollername-root' => [
'rule' => 'ean13/{:ean13}.html',
'controller' => 'mycontrollername',
'keywords' => [
'ean13' => ['regexp' => '[0-9]+', 'param' => 'ean13']
],
'params' => [
'fc' => 'module',
'module' => 'mymodulename'
]
]
];
}
So visiting https://www.example.com/ean13/12345.html will run your module controller and a GET variable ean13 will have a value of 12345.
Then create mycontrollername module controller where you can use postProcess() method to check if EAN exists.
public function postProcess()
{
$query = new DbQuery();
$query->select('id_product')
->from('product_attribute', 'pa')
->where('pa.ean13 = ' . (int)Tools::getValue('ean13'))
$productId = Db::getInstance(_PS_USE_SQL_SLAVE_)->getValue($query);
if ($productId) {
Tools::redirect($this->context->link->getProductLink($productId));
}
Tools::redirect('pagenotfound');
}
In query we check in product_attribute table as product combinations can have their own EAN13 and you also want those EAN13's to redirect to product page.
The basics of this answer is most commonly used to replace core product search controller with a custom and SEO friendly one.

Yii2 Trailing Slashes in URL is breaking the route

I configured UrlManager in a project and It was working the way I wanted.
Now i tried to add a content whose name contains a trailing slash but i get an error 404 (Object not found).
For example:
www.test.com/article/detail/id_of_article/title_of_article
title_of_article = People are ... => Work
title_of_article = 1/3 of People are ... => Doesn't Work (Object not Found)
The Trailing Slash is breaking the Url although it is encoded in %2F
This is how i create url:
Html::a(Html::encode($model->title),
['article/detail', 'id' => $model->id, 'title' => $model->title])
I don't really know how I can deal with that.
For This , the best solution is to use slug names.
Instead of id and title, take one more field called slug_name in your database.
On Add or update of any record generate slug name and store in db.
For generating slug name, you can use custom function as below.
public function getSlugName($id,$title)
{
$slug=$id;
if(isset($title) && $title!=null)
{
// remove all spacea
$slug.='-'.str_replace(' ','-',strtolower($title));
}
$slug=preg_replace('/[^A-Za-z0-9\-]/', '', $slug); // Removes special chars.
$slug=str_replace(array('--'), '-', $slug); // remove multiple --
return $slug;
}
This function will return you uniq name. So you can use it in url.
This is also help in SEO.
Could be you need URL normalization
Since version 2.0.10 UrlManager can be configured to use UrlNormalizer
for dealing with variations of the same URL, for example with and
without a trailing slash.
NB by default UrlManager::$normalizer is disabled. You need to explicitly configure it in order to enable URL normalization.
see how here http://www.yiiframework.com/doc-2.0/guide-runtime-routing.html#url-normalization
There is an encodeParams property of UrlRule. Please try with that.

How can I get elastic search to return results inside angle brackets?

I'm new to elastic search. I'm trying to fix our search so that it will allow users to search on content within html tags. Currently, we're using a whitespace tokenizer because we need it to return results on hyphenated names. Consequently, aname123-suffix project is indexed as ["aname123-suffix", "project"] and a user search for "aname123-*" returns the correct results.
My problem arises because we also want to be able to search on content within html tags. So, for example for a project called <aname123>-suffix project, we'd like to be able to enter the search term <aname123>-* and get back the correct results.
The index has the correct tokens for a whitespace tokenizer, namely ["<aname123>-suffix", "project"] but when my search string is "\<aname123\>\-suffix" or "\\<aname123\\>\\-suffix" elastic search returns no results.
I think the solution lies either in
modifying the search string so that elastic search returns <aname123>-suffix when I ask for it; or
being able to index the content within the tag separately from the whitespace tokens, i.e. ["<aname123>-suffix", "project", "aname123", "suffix"]
So far I've been approaching it by changing the indexing, but I have not yet succeeded. A standard tokenizer will allow search results for content within tags, but it fails to return search results for aname123-*. Currently my analyzer settings look like this:
{ "analysis":
{ "analyzer":
{ "my_whitespace_analyzer" :
{"type": "custom"
{"tokenizer": "whitespace},
{"filter": ["standard", "lowercase", "stop"]}
}
},
{ "my_tag_analyzer":
{"type": "custom"
{"tokenizer": "standard"},
{"filter": ["standard", "lowercase", "stop"]}
}
}
}
}
I can create a custom char filter that strips out the < and the >, so my index contains aname123; but for some reason elastic search still does not return correct results when searching on <aname123>*. However, when I use instead a standard analyzer, the index contains aname123 and it returns the expected results for <aname123>* ... What is so special about angle brackets in elastic search?
You may want to take a look at the html_strip character filter:
https://www.elastic.co/guide/en/elasticsearch/reference/current/analysis-htmlstrip-charfilter.html
An example from one of the elasticsearch developers is here:

How to use add_rewrite_rule function, while permalink structure is disabled?

I am using the add_rewrite_rule() function to modify my URL structure.
I'm wanting to use add_rewrite_rule to add a custom rule but these rules only get added in when other than default settings are selected in my permalink settings area.
i.e. in the settings there are following options:
- Default http://localhost/wordpress/?p=123
- Day and name http://localhost/wordpress/2014/08/14/sample-post/
- Month and name http://localhost/wordpress/2014/08/sample-post/
- Numeric http://localhost/wordpress/archives/123
- Post name http://localhost/wordpress/sample-post/
- Custom Structure http://localhost/wordpress
So, when I select other then 'Default', my add_rewrite_rule() function works, but while selecting 'Default', the function doesn't seem to be work. So please suggest me how to work the function in any condition. Any help would be Appriciated.
Update:
I think the problem lies here:
When I use this, while selecting 'Default':
get_option('permalink_structure');
I got nothing.
While in the other cases, there are some values like:
/%postname%/
/archives/%post_id%
/%year%/%monthnum%/%postname%/
The Default permalinks, or so called "Ugly" permalinks, are not adding anything to the .htaccess file, so the Apache rewrite engine is not enabled. Without the rewrite engine, no rewrites can be done. So the short answer is that rewrites are not possible with Default permalinks.
I can recommend you to use rewrites along with query vars. When adding a rewrite rule, pass your custom data to a query var, and build the functionality around that query var. This way your functionality will work in all situations and with all permalink types.
So for example if you have the following rule:
add_rewrite_rule('^sometest/([^/]*)/?','index.php?custom_query_var=$matches[1]', 'top');
and you have the custom_query_var added as a query var by using the following code:
function add_query_vars_filter( $vars ){
$vars[] = "custom_query_var";
return $vars;
}
add_filter( 'query_vars', 'add_query_vars_filter' );
then when Default permalinks are selected, the following URL would work for you:
http://yoursite.com/index.php?custom_query_var=abc
and if "Pretty" permalinks are selected, the URL rewriting would work and your URL would look the following way:
http://yoursite.com/sometest/abc/
which is basically the best that can be achieved with rewrites.
I agree with #Martin. Here's a resource that will help https://core.trac.wordpress.org/ticket/15235
use this:
function my_add_query_vars( $qvars ) {
$qvars[] = 'business-coaching';
$qvars[] = 'country';
$qvars[] = 'territory';
$qvars[] = 'region';
return $qvars;
}
add_action('query_vars', 'my_add_query_vars');
//Write the rule
function add_analytic_rewrite_rule()
{
// Regex:The regex to match the incoming URL is:business-coaching(/([^/]+))?(/([^/]+))?(/([^/]+))?/?
// Redirect Rule :The resulting internal URL: `index.php` because we still use WordPress
// `pagename` or page_id=45 because we use this WordPress page
// `country` : we will assign the first captured regex part to this variable
// `territory` we will assign the second captured regex part to this variable
// `region` we will assign the third captured regex part to this variable
add_rewrite_rule('business-coaching(/([^/]+))?(/([^/]+))?(/([^/]+))?/?','index.php?page_id=45&country=$matches[2]&territory=$matches[`enter code `enter code here`here`4]&region=$matches[6]','top');//superfinal
}
add_action('init', 'add_analytic_rewrite_rule');

Puppet Servers of same type

I have a best practice question around Puppet when working is server/agent mode.
I have created a working solution using a manifest/sites.pp configuration that identifies the configuration using the hostname of the agent.
For example:
node 'puppetagent.somedomain.com' {
include my_module
notify { 'agent configuration applied':
}
}
This works great for configuring a single node but what if I had a scenario in which I had multiple applications servers all with differing hostnames but all of which needed the same configuration.
Adding multiple node entries, comma separated hostname list or regular expressions doesn't feel like the 'right' way to do this.
Are there alternative ways? Can you define node 'types'? What do the community consider best practice for this?
Many thanks
If all the servers have the same configuration, inheritance, or the hieara hierarchy are the easiest ways to achieve this.
Once you need to maintain a larger set of systems where certain nodes have types such as 'web server' or 'database server' the configurations will diverge and the single inheritance model is not entirely sufficient.
You can use composition in those places. Take a peak at this article for more details.
Regular expressions might not be so bad, but I suppose the current trend is to use hiera_include.
You can do something dirty like this :
$roles = { 'webserver' => [ 'server1', 'server2', 'server3' ]
, 'smtp' => [ 'gw1', 'gw2' ]
}
node default {
$roles . filter |$k,$v| { $hostname in $v }
. each |$k,$v| { hiera_include($k) }
}
I would suggest taking a look at the concept of "roles and profiles" here: http://www.craigdunn.org/2012/05/239/
You can have multiple nodes all of which include the same configuration with a "profile" that includes one or more "roles".
As for defining multiple nodes with the same configuration or a "profile" containing "role(s)", I would suggest using hiera_include like #bartavelle mentioned. Except to use a common environment variable for identifying the nodes rather than using regular expressions.
