Laravel 5: Library class not found - laravel

I've installed this library from github:
https://github.com/robholmes/term-extractor
I placed the files under public/term-extractor.
I tried creating a route to test the results of the library, but I keep getting the error Class 'TermExtractor' not found.
Here is the route:
Route::get('/test', function()
{
require public_path() . '/term-extractor/src/TermExtractor/TermExtractor.php';
$text = 'Inevitably, then, corporations do not restrict themselves merely to the arena of economics. Rather, as John Dewey observed, "politics is the shadow cast on society by big business". Over decades, corporations have worked together to ensure that the choices offered by \'representative democracy\' all represent their greed for maximised profits. This is a sensitive task. We do not live in a totalitarian society - the public potentially has enormous power to interfere. The goal, then, is to persuade the public that corporate-sponsored political choice is meaningful, that it makes a difference. The task of politicians at all points of the supposed \'spectrum\' is to appear passionately principled while participating in what is essentially a charade.';
$extractor = new TermExtractor();
$terms = $extractor->extract($text);
// We're outputting results in plain text...
header('Content-Type: text/plain; charset=UTF-8');
// Loop through extracted terms and print each term on a new line
foreach ($terms as $term_info) {
// index 0: term
// index 1: number of occurrences in text
// index 2: word count
list($term, $occurrence, $word_count) = $term_info;
echo "$term\n";
}
});
What's wrong?

First you should put in your composer.json dependecy for that TermExtractor
"require": {
"robholmes/term-extractor" : "3.*"
}
Inside file app.php you need to do 2 things (something like this, dunno the proper name of alias and provider (be sure to do composer update before doing it)
First add provider
'providers' => [
term-extractor/TermExtractorProvider::class
]
Second add alias
'aliases' => [
'TermExtractor' => term-extractor\TermExtractor\Facades\TermExtractor::class,
]
That should give you alias TermExtractor which u can use in whole app without each time do require public_path() . '/term-extractor/src/TermExtractor/TermExtractor.php';
Hope it helps

Laravel 8 multilanguage routes and how get the translated link of the same page

I'm trying to make my test app in multilanguage way.
This question has two correlated questions:
First question:
I followed the second answer in How to create multilingual translated routes in Laravel and this help me having a multilanguage site and the route cached, but I've a question and some misunderstanding.
It's a good practice overwrite an app config as they do int the AppServiceProver.php, making:
Config::set('app.locale_prefix', Request::segment(1));
Isn't better to work with the Session::locale in any case?
Second question:
In my case I've two languages, and in the navbar I want to print just ENG when locale is original language, and ITA when session locale is English.
If I'm in the Italian page, the ENG link in the navbar should point to the same English translated page.
Working with the method used in the other question, I hade many problems caused by the:
Config::set('app.locale_prefix', Request::segment(1));
We overwrite the variable in the config file local_prefix, and every time I switch to English language the locale_prefix will change to 'eng' and this sounds me strange, another thing I did is this:
if ( $lang && in_array($lang, config('app.alt_langs')) ){
return app('url')->route($lang . '_' . $name, $parameters, $absolute);
}
We use the alt_langs where are defined only the alternative languages, and this is a problem cause if I pass the local lang, in my case 'it', like lang parameter, this will not be found cause, from the description, the alt_lang should not contain the locale language and you will be able to get only the translated string.
If I change the:
if ( $lang && in_array($lang, config('app.alt_langs')) ){
return app('url')->route($lang . '_' . $name, $parameters, $absolute);
}
in:
if ( $lang && in_array($lang, config('app.all_langs')) ){
return app('url')->route($lang . '_' . $name, $parameters, $absolute);
}
Now using app.all_langs I'm able to choose which URL you want and in which language I want.
How do I get the translated URL?
In the blade file I need to get the translated URL of the page, and if read the other question, we used the $prefix for caching the routes and giving to the route a new name ->name($prefix.'_home'); in this way I can cache all the route and I can call the routes using blade without prefix {{ route('name') }} but, needing the translated url of the actual page a made this on the top of the view:
#php
$ThisRoute = Route::currentRouteName();
$result = substr($ThisRoute, 0, 2);
if ($result =='it' ){
$routeName = str_replace('it_', '', $ThisRoute);
$url = route($routeName,[],true,'en');
} else {
$routeName = str_replace('en_', '', $ThisRoute);
$url = route($routeName,[],true,'it');
}
#endphp
Doing this I get the actual route name that should be it_home I check if start with it_ or en_, I remove the it_ or en_ prefix and I get the translated URL, now you can use the $url as <a href="{{ $url" }}>text</a> cause if I call the {{ route('page') }} I get the link, with the locale language.
This code is not very good, I know, but I written in 5 minutes, need more implementation, and check, but for the moment is just to play with Laravel.
It's a good way?? How can I do it better (except the blade link retrieving)?? Many solution I found used middleware, but I would like to avoid a link in the navbar like mysite.com/changelang?lang=en
Is a good approach overriding the app.locale_prefix?
First
according to your question, it's a bad practice to save the preferences into .env or session because as soon as the session is finished the saved language will be removed also it's common when you need to store any preferences related to your website such as (Color, Font, Language, ...etc) you must store any of them into the cache.
Second
honestly, your code is a very strange and NOT common way and there are two ways to handle what do you need
First
There is a very helpful and awesome package called mcamara it'll help you too much (I recommend this solution).
Second
you can do it from scratch using the lang folder located in the resource folder and you must create files with the same count of the needed languages then use the keys that you'll define into these files into views and you can prefix your routes with the selected language you can use group method like so
Route::group(['prefix' => 'selected_lang'], function() {
Route::get('first_route', [Controller::class, 'your_method']);
});
or you can add the selected language as a query string like so localhost:8000/your_route?lang=en you can follow this tutorial for more info.

Construct routes(urls) with slugs separated by dash in laravel

I am about to make more SEO-friendly URLs on my page and want a pattern looking like this for my products:
www.example.com/product-category/a-pretty-long-seo-friendly-product-name-12
So what are we looking at here?
www.example.com/{slug1}/{slug2}-{id}
The only thing I will care about from the URL in my controller is the {id}. The rest two slugs are just of SEO purpose. So to my question. How can I get the 12 from a-pretty-long-seo-friendly-product-name-12?
I have tried www.mydomain.com/{slug}/{slug}-{id} and in my controller to try and get $id. Id does not work. I am not able to able to separate it from from a-pretty-long-seo-friendly-product-name. So in my controller no matter how I do I get {slug2} and {id} concatenated.
Coming from rails it is a piece of cake there but can't seem to figure out how to do that here in laravel.
EDIT:
I am sorry I formulated my question very unclear. I am looking for a way to do this in the routes file. Like in rails.
You're on the right track, but you can't really logically separate /{slug}-{id} if you're using dash-separated strings. To handle this, you can simply explode the chunks and select the last one:
// routes/web.php
Route::get('/{primarySlug}/{secondarySlugAndId}', [ExampleController::class, 'example']);
// ExampleController.php
public function example($primarySlug, $secondarySlugAndId){
$parts = collect(explode('-', $secondarySlugAndId));
$id = $parts->last();
$secondarySlug = $parts->slice(0, -1)->implode('-');
... // Do anything else you need to do
}
Given the URL example.com/primary-slug/secondary-slug-99, you would have the following variables:
dd($primarySlug, $secondarySlug, $id);
// "primary-slug"
// "secondary-slug"
// "99"
The only case this wouldn't work for is if your id had a dash in it, but that's another layer of complexity that I hope you don't have to handle.
Route::get('/test/{slug1}/{slug2}','IndexController#index');
public function index($slug1, $slug2)
{
$id_slug = last(explode('-',$slug2));
$second_slug = str_replace('-'.$id_slug,'',$slug2);
dd($slug1, $second_slug,$id_slug);
}

View nested objects under Tinker

On Laravel Tinker when I run this:
>>> $customers = App\Customer::all();
I get a list of objects such as:
=> Illuminate\Database\Eloquent\Collection {#811
all: [
App\Customer {#815
id: 3,
favorite: 6,
user: App\User {#232 ...11},
zip: 11221
}
...
]
My question is how do I expand the user value where it has {#232 ...11}?
the tinker function of artisan is based almost entirely off of the psysh
see: https://github.com/bobthecow/psysh/
also: https://psysh.org/
inside psysh is a command called dump, dump is an implementation of symfony's var-dumper a newer kind of var_dump.
dump -h
shows:
Usage: dump [--depth DEPTH] [-a|--all] [--]
Arguments: target A target object or primitive to dump.
Options: --depth Depth to parse. (default: 10) --all (-a) Include
private and protected methods and properties.
Help: Dump an object or primitive. This is like var_dump but way
awesomer. e.g.
>>> dump $_
>>> dump $someVar
>>> dump $stuff->getAll()
for myself running with the argument --depth does not satisfy my object which is also rather large. so we see that psysh has a dependency on symfony's var-dumper.
see: https://github.com/symfony/var-dumper
also: https://symfony.com/doc/current/components/var_dumper.html
the advanced section states
The dump() function is just a thin wrapper and a more convenient way
to call VarDumper::dump(). You can change the behavior of this
function by calling VarDumper::setHandler($callable). Calls to dump()
will then be forwarded to $callable.
By adding a handler, you can customize the Cloners, Dumpers and
Casters...
A cloner is used to create an intermediate representation of any PHP
variable. Its output is a Symfony\Component\VarDumper\Cloner\Data
object that wraps this representation...
A cloner applies limits when creating the representation, so that one
can represent only a subset of the cloned variable. Before calling
cloneVar(), you can configure these limits:
setMaxItems()
Configures the maximum number of items that will be cloned past the minimum nesting depth. Items are counted using a breadth-first
algorithm so that lower level items have higher priority than deeply
nested items. Specifying -1 removes the limit. setMinDepth()
Configures the minimum tree depth where we are guaranteed to clone all the items. After this depth is reached, only setMaxItems items
will be cloned. The default value is 1, which is consistent with older
Symfony versions. setMaxString()
Configures the maximum number of characters that will be cloned before cutting overlong strings. Specifying -1 removes the limit.
see: https://symfony.com/doc/current/components/var_dumper/advanced.html
so what I am doing is creating a folder inside app named VarDumpFull then adding into file /app/VarDumpFull/VarDumpFull.php the following code
<?php
namespace App\VarDumpFull;
use Symfony\Component\VarDumper\Cloner\VarCloner;
use Symfony\Component\VarDumper\Dumper\CliDumper;
class VarDumpFull
{
public function __construct($var)
{
$cloner = new VarCloner();
$dumper = new CliDumper();
$cloner->setMaxItems(-1);
$cloner->setMaxString(-1);
$dumper->dump($cloner->cloneVar($var));
}
}
you can run this easily like so:
new VarDumpFull($variable_to_be_dumped);
remember to run to update your classes.
composer dump-autoload
You need to iterate over the collection to work with user property. If you want to do that in Tinker:
foreach ($customers as $customer) {
echo $customer->user->name;
}
If you just want to see the data structure, you can do this in Tinker:
$customers->first()->user
First of all you should load relationship:
$customers = App\Customer::with('user')->get();
but I assume you did it because you have user relationship visible on your output.
To get array representation of your customers together with relationships you should use:
foreach ($customers as $customer)
{
dump($customer->toArray());
}
obviously result won't be the same as you dump the whole collection but you will get all model attributes together with relations and I think this is what you want here.

Laravel 5.1 translate an array pass to blade

I have this in my controller
public function editProfile(Request $request){
$question1 = Question::where('group',1)->lists('question', 'id');
$question2 = Question::where('group',2)->lists('question', 'id');
return view('user', compact(''question1', 'question2'));
}
$question = {\"1\":\"What is the first name of your best friend in high school?\",\"2\":\"What was the name of your first pet?\",\"3\":\"What was the first thing you learned to cook?\",\"4\":\"What was the first film you saw in the theater?\"}
$question2 = {\"5\":\"Where did you go the first time you flew on a plane?\",\"6\":\"What is the last name of your favorite elementary school teacher?\",\"7\":\"In What city or town does your nearest sibling live?\"}
I would like to translate the value in both question 1 and question 2 and pass it to user blade without changing the key, Any suggestions?
As specified at the localization doc, you need to populate a lang file with translation strings. So, let's say you want to show both Spanish and English strings. In this case you'd need to create two files: /resources/lang/en/messages.php and /resources/lang/es/messages.php. The content of one of those files would be somewhat like this:
<?php
// resources/lang/es/messages.php
return [
'welcome' => 'Bienvenido'
];
This way, you could access the strings in there with the following method: __('messages.welcome'), which would return the string for the language set on your config/app.php -- the default entry is en, by the way, but you can set it to whatever you want. The value in there will define which language will be chosen when selecting strings.
Another method to create translation strings is using the string itself as key, storing them in a JSON file instead of PHP. For example, the following translation string:
{
"I love programming.": "Me encanta programar."
}
would be accessible through this: __('I love programming.').
Having said that, you may solve your problem through the two methods presented above. You could store in your DB keywords for the questions instead of the whole text, and create translation for as many languages as you want. Also, you could keep the questions in your database and create translation strings for those questions. Finally, you'd need to iterate over the fetched entries and translate each one of them, or use some Collection helper to do the hard work for you, like transform or map.

How to make client side I18n with mustache.js

i have some static html files and want to change the static text inside with client side modification through mustache.js.
it seems that this was possible Twitter's mustache extension on github: https://github.com/bcherry/mustache.js
But lately the specific I18n extension has been removed or changed.
I imagine a solution where http:/server/static.html?lang=en loads mustache.js and a language JSON file based on the lang param data_en.json.
Then mustache replaces the {{tags}} with the data sent.
Can someone give me an example how to do this?
You can use lambdas along with some library like i18next or something else.
{{#i18n}}greeting{{/i18n}} {{name}}
And the data passed:
{
name: 'Mike',
i18n: function() {
return function(text, render) {
return render(i18n.t(text));
};
}
}
This solved the problem for me
I don't think Silent's answer really solves/explains the problem.
The real issue is you need to run Mustache twice (or use something else and then Mustache).
That is most i18n works as two step process like the following:
Render the i18n text with the given variables.
Render the HTML with the post rendered i18n text.
Option 1: Use Mustache partials
<p>{{> i18n.title}}</p>
{{#somelist}}{{> i18n.item}}{{/somelist}}
The data given to this mustache template might be:
{
"amount" : 10,
"somelist" : [ "description" : "poop" ]
}
Then you would store all your i18n templates/messages as a massive JSON object of mustache templates on the server:
Below is the "en" translations:
{
"title" : "You have {{amount}} fart(s) left",
"item" : "Smells like {{description}}"
}
Now there is a rather big problem with this approach in that Mustache has no logic so handling things like pluralization gets messy.
The other issue is that performance might be bad doing so many partial loads (maybe not).
Option 2: Let the Server's i18n do the work.
Another option is to let the server do the first pass of expansion (step 1).
Java does have lots of options for i18n expansion I assume other languages do as well.
Whats rather annoying about this solution is that you will have to load your model twice. Once with the regular model and second time with the expanded i18n templates. This is rather annoying as you will have to know exactly which i18n expansions/templates to expand and put in the model (otherwise you would have to expand all the i18n templates). In other words your going to get some nice violations of DRY.
One way around the previous problem is pre-processing the mustache templates.
My answer is based on developingo's. He's answer is very great I'll just add the possibility to use mustache tags in the message keycode. It is really needed if you want to be able the get messages according to the current mustache state or in loops
It's base on a simple double rendering
info.i18n = function(){
return function(text, render){
var code = render(text); //Render first to get all variable name codes set
var value = i18n.t(code)
return render(value); //then render the messages
}
}
Thus performances aren't hit because of mustache operating on a very small string.
Here a little example :
Json data :
array :
[
{ name : "banana"},
{ name : "cucomber" }
]
Mustache template :
{{#array}}
{{#i18n}}description_{{name}}{{/i18n}}
{{/array}}
Messages
description_banana = "{{name}} is yellow"
description_cucomber = "{{name}} is green"
The result is :
banana is yellow
cucomber is green
Plurals
[Edit] : As asked in the comment follows an example with pseudo-code of plural handling for english and french language. Its a very simple and not tested example but it gives you a hint.
description_banana = "{{#plurable}}a {{name}} is{{/plurable}} green" (Adjectives not getting "s" in plurals)
description_banana = "{{#plurable}}Une {{name}} est verte{{/plurable}}" (Adjectives getting an "s" in plural, so englobing the adjective as well)
info.plurable = function()
{
//Check if needs plural
//Parse each word with a space separation
//Add an s at the end of each word except ones from a map of common exceptions such as "a"=>"/*nothing*/", "is"=>"are" and for french "est"=>"sont", "une" => "des"
//This map/function is specific to each language and should be expanded at need.
}
This is quite simple and pretty straightforward.
First, you will need to add code to determine the Query String lang. For this, I use snippet taken from answer here.
function getParameterByName(name) {
var match = RegExp('[?&]' + name + '=([^&]*)')
.exec(window.location.search);
return match && decodeURIComponent(match[1].replace(/\+/g, ' '));
}
And then, I use jQuery to handle ajax and onReady state processing:
$(document).ready(function(){
var possibleLang = ['en', 'id'];
var currentLang = getParameterByName("lang");
console.log("parameter lang: " + currentLang);
console.log("possible lang: " + (jQuery.inArray(currentLang, possibleLang)));
if(jQuery.inArray(currentLang, possibleLang) > -1){
console.log("fetching AJAX");
var request = jQuery.ajax({
processData: false,
cache: false,
url: "data_" + currentLang + ".json"
});
console.log("done AJAX");
request.done(function(data){
console.log("got data: " + data);
var output = Mustache.render("<h1>{{title}}</h1><div id='content'>{{content}}</div>", data);
console.log("output: " + output);
$("#output").append(output);
});
request.fail(function(xhr, textStatus){
console.log("error: " + textStatus);
});
}
});
For this answer, I try to use simple JSON data:
{"title": "this is title", "content": "this is english content"}

Make sure to remember that other languages are significantly different from EN.
In FR and ES, adjectives come after the noun. "green beans" becomes "haricots verts" (beans green) in FR, so if you're plugging in variables, your translated templates must have the variables in reverse order. So for instance, printf won't work cuz the arguments can't change order. This is why you use named variables as in Option 1 above, and translated templates in whole sentences and paragraphs, rather than concatenating phrases.
Your data needs to also be translated, so the word 'poop', which came from data - somehow that has to be translated. Different languages do plurals differently, as does english, as in tooth/teeth, foot/feet, etc. EN also has glasses and pants that are always plural. Other languages similarly have exceptions and strange idoms. In the UK, IBM 'are' at the trade show whereas in in the US, IBM 'is' at the trade show. Russian has several different rules for plurals depending on if they are people, animals, long narrow objects, etc. In other countries, thousands separators are spaces, dots, or apostrophes, and in some cases don't work by 3 digits: 4 in Japan, inconsistently in India.
Be content with mediocre language support; it's just too much work.
And don't confuse changing language with changing country - Switzerland, Belgium and Canada also have FR speakers, not to mention Tahiti, Haiti and Chad. Austria speaks DE, Aruba speaks NL, and Macao speaks PT.
