how to test existence of context variable using gulp-file-include - if-statement

I am using gulp-file-include to build my html pages using some partials & templates. By using context variables, I can customize each meta headers. However, don't know how I could include a line only if a context variable exists, as the "##else" statement doesn't seem to exist.
My parent HTML looks like:
##include ('_header.html', {
"title":"my page",
"description": "description",
"canonical":"http://www.sourcefromquote.com" })
<body>
A wonderful Page
##include ('_footer.html")
</body></html>
I was thinking to use a _header.html close to something like that :
<html>
<head>
<title>##title</title>
<meta name="description" content="##description">
##if (canonical) { <link rel="canonical" href="##canonical" /> }
</head>
If the "canonical" variable is not set in the the parent HTML, it throws an error (canonical is not defined).
I guess I could include the full tag in a variable and forget about the ##if, but that would not be as clean as expected !
Any ideas ?
Thank you in advance.

In the head, you enter:
##if (context.canonical) {<link rel="canonical" href="##canonical" />}
In the file that includes the header you enter:
##include('_head.html', {
"canonical" : "https://www.website.com/canonical-link.html"
})

A Livewire component was not found after creating a component in a custom path

As stated in the docs, you can create a component in a custom path, which is different from the default views/livewire/ and Http/Livewire. Just for the sake of better organization, I created subfolders:
$ php artisan make:livewire tutorial/counter
So I got my files in the following paths:
views/livewire/tutorial/counter.blade.php
Http/Livewire/Tutorial/Counter.php
To test the component in a view, I created a /livewire/tutorial/welcome.blade.php which has the following:
<!DOCTYPE html>
<html lang="{{ str_replace('_', '-', app()->getLocale()) }}">
<head>
<meta charset="utf-8">
<meta name="viewport" content="width=device-width, initial-scale=1">
<title>Livewire tutorial: counter</title>

When I hit the route, I get the following error:
Livewire\Exceptions\ComponentNotFoundException Unable to find
component: [counter]
I already have tried:
$ php artisan livewire:discover
But I still get that error.
What Am I missing?
Solved
Just like Najmus suggested, I tried:
<livewire:path.to.counter />
And that did the trick!
Try this in the welcome.blade.php file
<livewire:tutorial.counter />
instead of
<livewire:counter />
you can create components under subdirectory using php artisan make:livewire users.register User is your folder name and register is component...
and if you want to move existing component then simply you can run this command php artisan livewire:mv register users.register
ie : livewire:mv {your component name} {your folder name}.{component name}
instead of mv you can use move also
may this will help
-Check your class name propely(if any spelling mistake made).
-Check header in class defined or not.
-If component is not there then create one:
php artisan make:liveware component_name
In my case, i typed the extension along with the file name that why it was showing error.
<livewire:abandoned-property-case-list.blade.php/>
But this should be
<livewire:abandoned-property-case-list/>

LARAVEL Error: "Sorry, the page you are looking for could not be found."

I am using laravel version 5.5.45 and trying to learn Blade for first time. I created a file views/layout/app.blade.php. And want to extend that app.blade.php file in views/contact.blade.php. I extended the master blade file using #yield.
Do I need to do any change in route folder?
views/layout/views/layout/app.blade.php
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<meta http-equiv="X-UA-Compatible" content="ie=edge">
<title>Document</title>
</head>
<body>
#yield('content')
#yield('footer')
</body>
</html>
views/contact.blade.php
#extends('layouts.app')
#section('content')
<h1>Contact Pafg</h1>
#endsection
When I hit the URL localhost/cms/public/contact I see the error in title.
You need to add custom route in web.php which is located in routes directory.
At the end of file add following code to connect the defined route to your view.
Route::get('contact', function () {
return view('contact');
});
Finally you can access it via localhost/contact
First of all you need to put the request to get view on browser. Now assuming that your project name: cms lets assume you are calling cms/contacts ( this is a get request just to get simple blade view ). Now this will go to web.php in routes directory, where you need to handle that request e.g.
Route::get('contact', function() {
return view('contact');
})
here assuming your contact.blade.php is in your resources/views/contacts.blade.php path. if it is within any another nested directory need to add that directory name e.g. return view('directory_name/contact');.
You can perform same action using controller method in which case you need to specify controller and method name in route file and return blade in that method. e.g.
Route::get('contact', 'controller#methodName');
To return blade you need to use view('blade_name') helper of laravel and you don't have to call you request like cms/public/contact, simply use cms/contact url.
Hope this helps.

Go language strange behavior by handling templates

gotemplates
Hello!
I'm learning Go language now and trying to port some simple WEB code (Laravel 4).
Everything was well, until I tried to reproduce Blade templates into text templates.
I found that Go can load my CSS and JavaScript files only from the catalog with a name "bootstrap" only.
Here is my catalog tree which I tried to use:
start-catalog
bootstrap (link to bootstrap-3.3.1)
bootstrap-3.3.1
css
bootstrap.min.css
js
bootstrap.min.js
jquery
jquery (link to jquery-2.1.1.min.js)
jsquery-2.1.1.min.js
go_prg.go
Here are my templates:
base_js.tmpl
{{define "base_js"}}
{{template "login_1"}}
<script src = "/bootstrap/js/jquery"></script>
<script src = "/bootstrap/js/bootstrap.min.js"></script>
{{end}}
base_header.tmpl
{{define "base_header"}}
<head>
<title>PAGE TITLE</title>
<meta name = "viewport" content = "width=device-width, initial-scale=1.0">
<meta charset="utf-8">
<link href = "/bootstrap/css/bootstrap.min.css" rel = "stylesheet">
</head>
{{end}}
If the catalog name differs from "bootstrap" Go language or Firefox can't load files from the templates above: bootstrap.min.css, bootstrap.min.js, jquery.
If I use not the link but the catalog name directly "bootstrap-3.3.1" than Go or Firefox can't load.
If all required files are moved under "bootstrap" I'm getting the results I expected (exactly the same as in Laravel 4).
To launch go language code the command go run go_prg.go was used.
Environment: Ubuntu 14.04, go-1.3.3, Firefox 31.
Who's wrong: Go language, Firefox or me?
Any help will be highly appreciated!
The problem described was caused by
http.Handle("/bootstrap/", http.StripPrefix("/bootstrap/", http.FileServer(http.Dir("bootstrap"))))
before any template was handled. It allowed access files under the directory 'bootstrap' only.
The problem was fixed by changing to
http.Handle( , http.StripPrefix(, http.FileServer(http.Dir("."))))
and adding to pathes for CSS and JavaScript files. Like so
/bootstrap/js/jquery">.

dompdf: templates & $_SESSION variables

i was wondering if this setup would work. i have to crank out a batch of PDF from a bunch of variables i'm pushing into the $_SESSION via a form (duh...). the idea is to pass the template file to the dompdf engine and have the template populate from the $_SESSION then out to PDF. it seems to me that when the $template gets loaded it should do that, yes?
here's the basic code:
<?php
function renderToPDF($theTemplate = "template.php") // this is just to show the value
{
require_once("dompdf/dompdf_config.inc.php");
$content = file_get_contents($theTemplate);
if ($content !== false)
{
$dompdf = new DOMPDF();
$dompdf->load_html($content);
$dompdf->render();
$dompdf->stream("kapow_ItWorks.pdf");
}
}
?>
and this is the template.php file (basically... you don't want all 16 pages...)
<html>
<meta>
<head>
<link href="thisPage.css" type="text/css" rel="stylesheet">
</head>
<body>
<h1><?php echo $_SESSION['someTitle'] ?></h1>
<h2>wouldn't it be nice, <?php echo $_SESSION['someName'] ?></h2>
</body>
</html>
so my thinking is that the template.php will pull the variables right out of the $_SESSION array without any intervention, looking like this:
BIG TITLE
wouldn't it be nice, HandsomeLulu?
i guess the nut of the question is: Do $_SESSION variables get evaluated when PHP files are loaded, but not rendered?
WR!
file_get_contents does not evaluate the PHP file, it simply gets its contents (the file as it is in the hard drive).
To do what you want, you need to use output buffering and include.
ob_start(); // Start Output beffering
include $theTemplate; // include the file and evaluate it : all the code outside of <?php ?> is like doing an `echo`
$content = ob_get_clean(); // retrieve what was outputted and close the OB
for some reason, the code ON the page that calls the function ALSO gets dumped into the file. this was placed before the header. i understand now why: i wasn't referencing an external page, i was importing and external page. don't know why that didn't click.
anyway. as soon as i got rid of the page's extra stuff, it worked just fine. in retrospect, what dompdf needed to state was quite simply that NO HTML of ANY kind (echo, print, &c.) can be on the page that calls the function. at least that what it appears to require at this level of my knowledge.
for those who, like me, are floundering in a misma of 'everything but the answer', here's the bare bones code that did the job:
buildPDF.php:
<?php
session_start();
$_SESSION['someTitle'] = "BIG FAT TITLE";
$_SESSION['someName'] = "HandomeLu";
$theTemplate = 'template.php';
function renderToPDF($templateFile)
{
require_once("_dox/dompdf/dompdf_config.inc.php");
ob_start();
include $templateFile;
$contents = ob_get_clean();
if ($contents !== false)
{
$dompdf = new DOMPDF();
$dompdf->load_html($contents);
$dompdf->render();
$dompdf->stream("kapow_ItWorks.pdf");
}
}
renderToPDF($theTemplate);
?>
and this is the template.php:
<!DOCTYPE HTML>
<html>
<meta>
<head>
<meta charset="utf-8">
<link href="thisPage.css" type="text/css" rel="stylesheet">
</head>
<body>
<h1><?php echo $_SESSION['someTitle'] ?></h1>
<p>wouldn't it be nice, <?php echo $_SESSION['someName'] ?></p>
</body>
</html>
also note that the external CSS file reads in just fine. so you can still keep the structure and style separate. also, the $_SESSION variables can be set anywhere, obviously, i just set them here to keep testing easy.
hope this is useful for those getting started with this GREAT class. if you're looking to get up and running cranking out PDF files, this kicks so much butt, it should have a trigger and a grip on it. :)
thanks to everyone who commented. you got me in the place i needed to be. :)
this site ROCKS.
WR!

How to assign a GSP variable in a Grails template body()?

In my Grails 1.3.7 app, I'd like to use a template to factor out surrounding HTML from views. But, GSP variable assignment isn't working in the contained body(). How can I do something like the following?
_aTemplate.gsp:
<div class="example">
<% out << body() %>
</div>
aView.gsp:
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />
<meta name="layout" content="main" />
</head>
<body>
<g:set var="foo" value="${42}"/>
<% assert foo == 42 : foo %>
<tmpl:/aTemplate>
<g:set var="bar" value="${6}"/>
<% assert bar == 6 : bar %>
</tmpl:/aTemplate>
</body>
</html>
The assignment of bar doesn't work: the bar assertion fails, when I get http://localhost:8080/myApp/aView.gsp
org.codehaus.groovy.grails.web.taglib.exceptions.GrailsTagException:
Error executing tag<g:render>: Assertion failed:
(bar == 6). Values: bar = null
at /Users/jbeutel/proj/grailsSandboxes/myApp/grails-app/views/aView.gsp:13
How can I make the template body() work as normal?
Alternatively, is there some other way I could factor out surrounding HTML while keeping it balanced? My use case isn't at the top level, so I haven't tried using layouts. The variable assignment works if I use a TagLib closure instead of a template file, but I don't want to put a lot of HTML into a closure, so I would need to put unbalanced HTML into template files anyway (i.e., separate templates before and after the body). Is there a better way?
You can pass variables from your .gsp into shared templates that it can then consider as follows. I do this to hide a 'login' link in my common header if they are on the login.gsp page
<g:render template="/layouts/header" model="['hidelogin':true]"/>
then in the _header.gsp
<g:if test="${!hidelogin}">
//show your login link
</g:if>
