How do I use more than one Pelican theme simultaneously? - themes

I want to use a theme cloned from GitHub into my themes directory for almost all pages and articles and automatically-generated pages except for my landing page whose template is not part of the cloned theme and which uses its own particular css..
Currently my working site uses a new template file and related images, js and css files added to the cloned theme. But that's not what I want.
I want to keep separate the landing page's template and related files from the cloned theme but don't understand what settings and / or content file's metadata to use to point to a different theme path just for that one page
i.e. I want to override the THEME settings on just one page.
Settings THEME, CSS_FILE, DIRECT-TEMPLATE and TEMPLATE_PAGES don't seem to be exactly what I want. But maybe they are?

You have a couple of different options. Personally, I'd go with the first method, but I've used all three of these in different situations.
The index.html method
With this method, you create an index.html file that is straight up HTML - exactly how you want your index.html page to look. You can use Jinja variables in it, which is important if you're including CSS that's in your theme (as opposed to using hosted libraries), but mostly, it just looks exactly like you want it to look. A very simple example:
<html>
<head>
<title>My Title</title>
<link href="{{ SITEURL }}/theme/css/mystyles.css" rel="stylesheet" type="text/css">
<body>
<h1>Hello world!</h1>
</body>
</html>
You can then tell Pelican not to render .html files by including this line in your pelicanconfig.py:
READERS = {'html': None}
This will not prevent Jinja from processing Jinja templates in the HTML document.
Finally, because you aren't including any metadata about the HTML file in the HTML file itself (that's what the READERS = {'html': None} business is all about), you have to tell Pelican where to put the final index.html, by setting the TEMPLATE_PAGES variable, also in your pelicanconf.py file:
TEMPLATE_PAGES = {
'index.html' : 'index.html'
}
Now you can see your page by going to localhost/ in your browser.
If you wanted to put the file at a different location, you can specify any location you want:
TEMPLATE_PAGES = {
'index.html' : 'mydirectory/mypage.html'
}
which would make your page accessible at localhost/mydirectory/mypage.html.
Include alternate CSS file in Markdown
Since most HTML works verbatim in Markdown posts, you could also modify your landing page Markdown file to include a CSS file at the top,
Title: My Index
Author: Clark Kent
Date: 2010-12-03 10:20
Category: StackOverflow
<link href="{{ SITEURL }}/theme/css/mystyles.css" rel="stylesheet" type="text/css">
# Hello World
Welcome to the landing page!
Add metadata to control theme
Lastly, you could modify the theme directly to include a metadata attribute that controls what stylesheets the theme uses. For example, let's use the WhichTheme: metadata flag. We'll specify WhichTheme: index for our index Markdown page, and WhichTheme: notindex (or nothing) for all other pages. Then in our theme files, we'll look for the template used to render all pages (usually pages.html), and we'll add a Jinja conditional to check for our new variable, which is accessible at page.WhichTheme:
{% if page.WhichTheme=='index' %}
<link href="{{ SITEURL }}/theme/css/mystyles.css" rel="stylesheet" type="text/css">
<h1>{{ page.title }}</h1>
{% else %}
<h1>{{ page.title }}</h1>
{% endif %}

laravel blade template - how to remove a part from extended page

Note: Like i said in the comment, i am working relatively large project. I can't change existing codes. Just try to add some code blocks for one page.
I have a template blade. It has meta yield. But also included one meta.blade.php, that contains all meta tags. But i don't want to include metapage for some of my pages. There is the template for visualization:
my_template
<header>
#yield('meta')
#include('metapage')
#yield('style')
#yield('js')
</header>
my view.blade.php
#extends('my_template')
#section('meta')
<meta description...>
#endsection
#section('style')
//content
#endsection
#section('js')
//content
#endsection
My question is: Is there a way to make something like this:
#extends('my_template')->except('metapage')
I know there isn't exist something like that. But i need that. I hope somebody can give me a solution.
There is a certain solution which I do:
First one is to create multiple template and extend them as your requirements.
Second one is to disable sub parts.
Third one to create parent template having little things, then create child template which is extending parent and do extra things here. use it as your need.
If You are working on existing project and you have a lot of pages then First & third one is a better solution for it because you could make changes only in front end without affecting class code.
You could make the meta a component rather than an include, then your template would look the same and your view would be e.g.
#extends('my_template')
#section('meta')
#component('meta')
#slot('description', 'my amazing description')
#endcomponent
#endsection
// other code here as usual
Your component is then responsible for checking what exists and what doesn't, e.g. like this:
#isset($description)
<meta name="description" content="{{ $description }}">
#endisset
#isset($title)
<title>{{ $title }}</title>
#endisset
// etc, the title is just an example

Take the Tag Name Which You Want To ignore And Apply the CSS
ex: If I need to Remove the Footer From the Extended Page make
footer {
display: none;
}

why is blade making a head tag?

I'm using a Laravel app with an external public directory, e.g. root/Laravel, and root/html/public.
I need this app to load from a require on an php file that already has another framework(root/html/this-section.php), hence that other fw has its own head, and body tag. This app will load between the header and footer of that index.
In my blade layout.app file, i have
#section('stylesheets')
<link rel="stylesheet" href="/this-section/css/vendors.css">
<link rel="stylesheet" href="/this-section/css/app.css">
#show
<div id="main">
#include('layouts.sidebar')
#include('layouts.header')
<section>
#yield('content')
</section>
</div>
The issue I'm having is if no my app layout, when I delete the head and body tags during testing, which is what i need, the blade system, or what i dont know, is still creating an empty head tag set, <head></head>, then when i enable the stylesheets section, it ends up in that <head> tag.
Expected: The head tag should not be there. I don't want a head tag. What in laravel can i adjust to remove this auto creation of head (and body)?
It sounds like your using tags that belong in the <head> section is causing this. While your source may be pristine:
browsers will add in the missing-but-required tags as appropriate, resulting in you seeing them in the browser's web inspector:

Laravel 5 proper way to require CSS file from view

I've got specific Form component, which is declared as
Form::component('fcRadio', 'components.form.fcradio', ['name', 'options', 'selected' => null]);
and used as
{{ Form::fcRadio('name', $options }}
What I want is somehow attach custom CSS file, so if the page fires this component at least once, the desired CSS file is included to the <head> of my document.
For example, in Joomla it was like
$this->document->addStylesheet('my_awesome_style.css');
Is there any way to achieve the same in Laravel?
UPD:
I've extended the answers below a bit to let it add multiple styles from multiple templates. Finally, it looks like this:
#section('styles')
#parent
{{HTML::style('css/fcradio.css')}}
#stop
It works fine, but if I use the component twice per page, style is also adds twice. How can I allow multiple but unique entries?
So this is typically how I deal with it:
In your folder: resources/views I create a folder called layout. This folder handles the templates for all my pages.
Then I create a file called default.blade.php. In it I put the bulk of the HTML code. Here's an example of how default.blade.php could look (slimmed down, obviously)
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="utf-8">
<meta http-equiv="x-ua-compatible" content="ie=edge">
<meta name="viewport" content="width=device-width, initial-scale=1">
<title>
#yield('title')
</title>
<link rel="stylesheet" href="{{ asset('css/main.css') }}">
<!-- Additional per-page css -->
#yield('css')
</head>
<body>
#yield('content')
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.4/jquery.min.js"></script>
<script src="js/script.js"></script>
<script src="{{ asset('js/bootstrap.min.js') }}"></script>
<!-- Include per-page JS -->
#yield('js')
</body>
</html>
Right, so essentially what we have so far is the #yield() and asset() helpers.
#yield() is special blade syntax that Laravel uses to say, "Okay. Any time a blade view that is inheriting THIS master template calls the section named in this #yield() I will display that content right here.
asset() is a nifty little helper that basically appends your URL structure onto the string you pass it. So if your url is http://MyGreatSite.com and you use asset('js/script.js') it will spit out a fully qualified URL that will work anywhere on the site (http://MyGreatSite.com/js/script.js). asset() is great because you can use it in blade templates that will get sent out as an email and all of the files will work in an email inbox because they are absolute links.
Right. So now we have this master template and we need to use it. So what I do is create another view in the resources/views directory. Lets say we're doing a contact page. I would make contact.blade.php. Now I want to inherit that master template we created. So we do that like so:
#extends('layout.default)
#section('css')
<link rel="stylesheet" href="{{ asset('css/contact.css') }}">
#stop
#section('title')
Contact Us
#stop
#section('content')
<h1>Contact us</h1>
<p>
Contact us via email: contact#mygreatsite.com
</p>
#stop
#section('js')
<script src="{{ asset('js/contact-form.js') }}"></script>
#stop
Okay, so, first things first. At the very top we tell this blade file that we want to use the template we just made. We use the blade helper #extends() and pass it the path to our view relative to the views directory separated by periods.
Next, we want to create the sections that correspond to the template. We do that by opening the section with #section() and passing the name of the section we want to push this block of content to. We write our content and then we close the section by using #stop. Pretty simple. For images, css, or js, we simply use the asset() helper again.
I know it's a little long-winded, but hopefully that helps and explains the process a little better.
tl;dr: Use #yield(), #section(), and asset().
So I think I understand what you are saying.
In your blade layout file create a section inside the head:
<head>
#yield('componentcss')
</head>
And in the component do:
#section('componentcss')
{{HTML::style('css/fcradio.css')}}
#stop
You could also just include the css but I wouldn't advise this:
#section('componentcss')
<style>
.exampleclass {text-align:center;}
</style>
#stop
Hopefully I have understood you correctly.
I've finally found a bit tricky but working solution:
#hasSection('fcRadioStyle')
#else
#section('fcRadioStyle')
{{Html::style('css/components/fcradio.css')}}
#stop
#section('styles')
#yield('fcRadioStyle')
#append
#endif
This makes by Form::fcRadio append this style only once

Convert markdown to html with a table of contents using Redcarpet

My goal is to convert a markdown document to html, with a table of contents at the top. I saw that Redcarpet has a HTML_TOC option, which is really nice. But when I use it, it only renders the TOC, it does not include the rest of the document.
renderer = Redcarpet::Render::HTML_TOC.new(with_toc_data: true)
markdown = Redcarpet::Markdown.new(renderer)
html = markdown.render(File.read(input_file))
How do I render both the TOC and document itself in the same html page?
The only thing I can think of is to render two separate html objects, then combine them. But that is a little messy because I'd have to parse out the head/body tags properly before combining them. Is there a better way?
The only thing I can think of is to render two separate html objects, then combine them.
That would be exactly what you need to do. As a reminder, Markdown does not render a complete HTML document anyway. You only get an HTML fragment. For example a simple Markdown document:
A simple Markdown document.
gets rendered as the following HTML fragment:
<p>A simple Markdown document.</p>
However, for a complete, valid HTML document you need (at least) the following:
<!DOCTYPE html>
<html>
<head>
<title>Page Title</title>
</head>
<body>
<p>A simple Markdown document.</p>
</body>
</html>
Considering that you need to generate all of that anyway, how is it "messy" to obtain the TOC and the body separately?
In fact, in more sophisticated systems, the TOC may be in a sidebar or something. Therefore, using a templating system, the TOC can be passed to a template separately anyway, where it is then placed in a container which separates it from the document body for positioning and styling by CSS.
The exact template syntax might vary depending on which tools you use, but perhaps something like this:
<!DOCTYPE html>
<html>
<head>
<title>{{ page.title }}</title>
</head>
<body>
<aside>
{{ page.toc }}
</aside>
<div id="body">
{{ page.body }}
</div>
</body>
</html>
Of course, you don't have to use a template, but is certainly is a "clean" way to generate a document.

How does Jekyll use post.html to generate pages?

I'm having some difficulty getting Jekyll to use a particular theme and I think there's something fundamental I'm missing about how {{ content }} works with posts.
So, in a generic Jekyll site, index.html has a layout specified in its front matter. When the site is generated, the layout includes index.html as {{ content }}. It's kind of inverted, where the page specifies the layout and then the layout calls the page, but simple enough.
Posts, on the other hand, are all generated via a file, post.html, which resides in the _layouts folder even though it isn't really a layout. Like index.html it's essentially just a for loop. This is where I'm running into trouble.
Is post.html a required file? Could I rename it story.html?
Why does post.html require a layout in the front matter? The actual post, that is, the markdown that contains the text for said post, also requires a layout in its front mater. Is there a circumstance where post.html would have a different layout than the layout specified in the markdown file?
Edit: one other question. Why is {{ content }} called in multiple places? index.html and the layout file both have {{ content }}. Why doesn't the layout simply {% include %} index.html and let index.html call {{ content }}
I think you largely figured it out by yourself, but I'll still explain it in my own words.
You're right that {{ content }} is the placeholder in the layout file where the content of the actual page will go.
What probably confused you is the fact that you can build a set of nested layout files where one "inherits" from the other, and each layout has its own {{ content }}.
And yes, I didn't find anything about this in the docs, I figured it out by myself or better, by looking at examples.
So here's an example for you.
First, a default layout and a page:
/_layouts/default.html:
<!DOCTYPE html>
<html>
<head>
<title>{{ page.title }}</title>
</head>
<body>
<h1>{{ page.title }}</h1>
{{ content }}
</body>
</html>
/index.md:
---
title: example page
layout: default
---
This is the page content.
The generated HTML will look like this:
<!DOCTYPE html>
<html>
<head>
<title>example page</title>
</head>
<body>
<h1>example page</h1>
<p>This is the page content.</p>
</body>
</html>
Now let's create another layout file that "inherits" from the first one.
You'll probably want to use something like this if you're building a blog with Jekyll.
The layout file shown above is the default for all pages, blog posts and regular ones.
When you want all blog posts to contain additional information like post date and user, tags and so on.
For this, you can create a second layout file which uses the first one:
/_layouts/post.html:
---
layout: default
---
<div class="blogpost">
<i>post date: {{ page.date }}</i>
{{ content }}
</div>
And a blog post which uses this layout:
/_posts\2015-04-08-example-post.md:
---
title: example post
layout: post
---
This is the post content.
And the generated HTML:
<!DOCTYPE html>
<html>
<head>
<title>example post</title>
</head>
<body>
<h1>example post</h1>
<div class="blogpost">
<i>post date: 2015-04-08 00:00:00 +0200</i>
<p>This is the post content.</p>
</div>
</body>
</html>
In other words, something like this happened:
Jekyll used the post layout and put the content of the post into {{ content }}
Jekyll used the default layout and put the complete generated HTML from step 1 into {{ content }}
(no idea if Jekyll really does things in this order under the hood, but you get the idea)
You can see another example if you create a new Jekyll project as shown in the "Quick-start Instructions" on the home page of the Jekyll site.
The example site that Jekyll (version 2.1.1 on my machine) creates has three layout files, two of which (page and post) inherit from the default one.
I have an answer for myself, sort of. Each markdown file is assigned a layout in the front matter. But this "layout" isn't really a layout at all or it's a partial layout?
The terminology escapes me, so I'll just list the steps.
1) The markdown file has layout: post
2) Whatever is in the markdown file gets processed and then sent over to the logic residing in post.html. Here's the part that I wasn't getting right off: post.html has it's own layout. That's what's up in the front matter. Essentially we have the layout's layout.
3) The outer "layout" (default.html in a vanilla jekyll install), wraps itself around the inner "layout" (post.html), which wraps itself around the actual {{ content }}.
post.html could be named whatever, so long as the various layout lines are properly set.
I still don't know why {{ content }} winds up at the top of the layout stack only to be passed all the way back down. I'm not even sure "passed" is the right word when dealing with liquid. I like Jekyll, but it's kind of a nest of snakes.
