# Picea
|
||||
|
||||
Welcome to the official Picea documentation.
|
||||
|
||||
This library offers modern features from templating language, while simply generating normal PHP after compilation, such as view inheritance, definable blocks, 'or' token on unrunned looped, etc...
|
||||
|
||||
Picea uses the same delimiters that Twig uses, which are `{% %}`, `{{ }}` and `{# #}`.
|
||||
|
||||
The first `{% %}` is used for most **control structure** and **extensions**.
|
||||
|
||||
The `{{ }}` delimiter is used to **echo escaped content** in a page. (see *01-echoing*)
|
||||
|
||||
The `{# #}` is exclusively used as a **comment** enclosure. (see *01-comment*)
|
||||
|
||||
## Quick start
|
||||
|
||||
Render a simple Picea view:
|
||||
|
||||
```php
|
||||
$picea = new Picea\Picea();
|
||||
$picea->renderHtml('view/path/hello_world');
|
||||
```
|
||||
|
||||
And the view content could look like:
|
||||
|
||||
*path/hello_world*
|
||||
```html
|
||||
<!DOCTYPE html>
|
||||
<html>
|
||||
<head>
|
||||
<title>Picea's simple </title>
|
||||
</head>
|
||||
<body>
|
||||
<nav>
|
||||
{% foreach $navigation as $navItem %}
|
||||
<a href="{% route $navItem->route %}" title="{{ $navItem->description }}">
|
||||
{{ $navItem->caption }}
|
||||
</a>
|
||||
{% endforeach %}
|
||||
</nav>
|
||||
|
||||
{{ $someText }}
|
||||
</body>
|
||||
</html>
|
||||
```

# Control structures - Comments
|
||||
|
||||
There is no single-line token to comment code within Picea, it's a tag working as such :
|
||||
|
||||
**[PICEA]** So, using this code:
|
||||
|
||||
```html
|
||||
{# This is how you comment in a Picea view #}
|
||||
|
||||
<div>
|
||||
{# Is it hello or good bye ? not sure on this ! #}
|
||||
<i>Good bye world !</i>
|
||||
</div>
|
||||
|
||||
{# This is a multi-line comment
|
||||
<div>This part will not be rendered</div>
|
||||
#}
|
||||
```
|
||||
|
||||
**[HTML]** Would render as such:
|
||||
|
||||
```html
|
||||
<div>
|
||||
<i>Good bye world !</i>
|
||||
</div>
|
||||
```

# Echoing text or data
|
||||
|
||||
There is two token groups that you can use to print content into a view, `echo` or `print`.
|
||||
|
||||
Escaped by default : `{% echo $argument %}` = `{{ $argument }}` = `{% print $argument %}`
|
||||
|
||||
Raw when needed: `{% echo.raw $argument %}` = `{{= $argument }}` = `{% print.raw $argument %}`
|
||||
|
||||
## Outputing content to a view using `echo` / `{{ }}` / `print`, `echo.raw` / `{{= }}` / `print.raw`
|
||||
|
||||
Using `print` or `echo`, which are, by default, made safer by using PHP's native `htmlspecialchars`.
|
||||
|
||||
**[PICEA]** So, using this code:
|
||||
|
||||
```html
|
||||
{{ "Hello World !" }}
|
||||
|
||||
{% echo "This is another way to output <safe> content" %}
|
||||
|
||||
{% print "This is the third way to output <safe> content" %}
|
||||
|
||||
<hr>
|
||||
|
||||
{% echo.raw $someHTML %}
|
||||
|
||||
{% print.raw $someOtherHTML %}
|
||||
|
||||
{{= $someMoreHTML }}
|
||||
```
|
||||
|
||||
**[PHP]** Would yield internally:
|
||||
|
||||
```php
|
||||
<?php echo htmlspecialchars((string) "Hello World !", 3, 'UTF-8', true) ?>
|
||||
|
||||
<?php echo htmlspecialchars((string) "This is another way to output <safe> content", 3, 'UTF-8', true) ?>
|
||||
|
||||
<?php echo htmlspecialchars((string) "This is another way to output <safe> content", 3, 'UTF-8', true) ?>
|
||||
|
||||
<hr>
|
||||
|
||||
<?php echo $someHTML ?>
|
||||
|
||||
<?php echo $someOtherHTML ?>
|
||||
|
||||
<?php echo $someMoreHTML ?>
|
||||
```
|
||||
|
||||
## Using string format variant `printf` / `printf.raw`
|
||||
|
||||
Those tokens represents the equivalent of the printf() function from PHP.
|
||||
|
||||
**[PICEA]** So, using this code:
|
||||
|
||||
```html
|
||||
{% php
|
||||
$num = 5;
|
||||
$location = 'tree';
|
||||
%}
|
||||
<span>{% printf 'There are %d monkeys in the %s', $num, $location %}</span>
|
||||
<i>{% printf.raw 'There are %d monkeys in the %s', $num, $location %}</i>
|
||||
```
|
||||
|
||||
**[PHP]** Would render internally as :
|
||||
|
||||
```php
|
||||
<?php
|
||||
$num = 5;
|
||||
$location = 'tree';
|
||||
?>
|
||||
<span><?php echo htmlspecialchars((string) sprintf('There are %d monkeys in the %s', $num, location), 3, 'UTF-8', true); ?></span>
|
||||
<i><?php printf('There are %d monkeys in the %s', $num, location) ?></i>
|
||||
```

# Control structure - Comparisons
|
||||
|
||||
Most control structures used within PHP view templates are supported natively in Picea.
|
||||
|
||||
The goal for this project always has been to not loose original feature while removing some limitations with PHP's original templating syntax.
|
||||
|
||||
## Comparison using `if` / `then` / `else` / `elseif` / `endif`
|
||||
|
||||
Comparisons works the same way as using PHP's alternative syntax.
|
||||
|
||||
This is also how they are rendered in the compilation process.
|
||||
|
||||
**[PICEA]** So, using this code:
|
||||
|
||||
```html
|
||||
{% php $search = 'Pack my box with five dozen liquor jugs' %}
|
||||
|
||||
{% if strpos($search, 'beer') !== false %}
|
||||
<span>Found 'beer' into {{ $search }} !</span>
|
||||
{% elseif strpos($search, 'liquor') !== false %}
|
||||
<span>Found 'liquor' into {{ $search }} !</span>
|
||||
{% else %}
|
||||
<b>Neither 'beer' or 'liquor' were found in {{ $search }}</b>
|
||||
{% endif %}
|
||||
```
|
||||
|
||||
**[PHP]** Would yield:
|
||||
|
||||
```php
|
||||
<?php $search = 'Pack my box with five dozen liquor jugs'; ?>
|
||||
|
||||
<?php if (strpos($search, 'beer') !== false): ?>
|
||||
<span>Found 'beer' into <?php echo htmlspecialchars((string) $search, 3, 'UTF-8', true) ?> !</span>
|
||||
<?php elseif (strpos($search, 'beer') !== false): ?>
|
||||
<span>Found 'liquor' into <?php echo htmlspecialchars((string) $search, 3, 'UTF-8', true) ?> !</span>
|
||||
<?php else: ?>
|
||||
<b>Neither 'beer' or 'liquor' were found in <?php echo htmlspecialchars((string) $search, 3, 'UTF-8', true) ?></b>
|
||||
<?php endif ?>
|
||||
```
|
||||
|
||||
And then, the code would be runned through PHP's native `include` mechanic.
|
||||
|
||||
## Comparison using `switch` / `case` / `break` / `endswitch`
|
||||
|
||||
Using switches within HTML in plain PHP can be quite cumbersome because of it's limitation
|
||||
disallowing any output (including whitespace) between it's statement.
|
||||
|
||||
Picea will allow some more complex (and readable) switches within your views.
|
||||
|
||||
**[PICEA]** So, using this code:
|
||||
|
||||
```php
|
||||
{% php $selected = random_int(0,5) %}
|
||||
|
||||
{% switch $selected %}
|
||||
|
||||
{% case 1 %}
|
||||
{{ "One person selected" }}
|
||||
{% break %}
|
||||
|
||||
{% case 2 %}
|
||||
{% default %}
|
||||
{{ "Multiple person ($selected) selected" }}
|
||||
{% break %}
|
||||
|
||||
{% endswitch %}
|
||||
```
|
||||
|
||||
**[PHP]** Would render as such:
|
||||
|
||||
```php
|
||||
<?php $selected = random_int(0,5) ?>
|
||||
|
||||
<?php switch($selected):
|
||||
|
||||
case 1: ?>
|
||||
<?php echo htmlspecialchars((string) "One person selected", 3, 'UTF-8', true) ?>
|
||||
<?php break; ?>
|
||||
|
||||
<?php case 2: ?>
|
||||
<?php default: ?>
|
||||
<?php echo htmlspecialchars((string) "Multiple person ($selected) selected", 3, 'UTF-8', true) ?>
|
||||
<?php break; ?>
|
||||
|
||||
<?php endswitch; ?>
|
||||
```

# Control structure - `extends` / `section`
|
||||
|
||||
A nice feature of most robust templating engine is the ability to inherit from other view.
|
||||
|
||||
Picea follows a similar train of tought, since it's also possible create a chain of inheritance
|
||||
using `extends` which have definable parts you can declare using `section`.
|
||||
|
||||
## Basic `extends` (string $path)
|
||||
|
||||
You must provide a valid `$path` from which the template will be inherited.
|
||||
|
||||
**[PICEA]** So, using this code:
|
||||
|
||||
*path/base/layout.phtml*
|
||||
```html
|
||||
<!DOCTYPE html>
|
||||
<html>
|
||||
<head>
|
||||
{% section "head" %}
|
||||
<meta charset="utf-8">
|
||||
<meta name="viewport" content="width=device-width, initial-scale=1">
|
||||
<title>{{ title() }} - AnExampleApp</title>
|
||||
{% section %}
|
||||
</head>
|
||||
<body>
|
||||
<header id="header"">
|
||||
{% section "header" %}{% view "path/base/navigation" %}{% endsection %}
|
||||
</header>
|
||||
<main id="main">{% section "main" %}{% endsection %}</main>
|
||||
<footer id="footer">
|
||||
{% section "footer" %}
|
||||
© Copyright {{ date('Y') }}
|
||||
{% endsection %}
|
||||
</footer>
|
||||
</body>
|
||||
</html>
|
||||
```
|
||||
|
||||
*path/home.phtml*
|
||||
```html
|
||||
{% extends "path/base/layout" %}
|
||||
|
||||
{% title "Home page" %}
|
||||
|
||||
{% section "main" %}
|
||||
<h1>Welcome !</h1>

|
||||
</article>
|
||||
{% endsection %}
|
||||
```
|
||||
|
||||
**[HTML]** Would render as such :
|
||||
```html
|
||||
<!DOCTYPE html>
|
||||

|
||||
<head>
|
||||
<meta charset="utf-8">

|
||||
<a href="#home">Home</a>

|
||||
</footer>
|
||||
</body>
|
||||
</html>
|
||||
```
|
||||
|
||||
### Inherit an already extended view
|
||||
|
||||
We could use the previous file `path/home` and generate, let's say, the same page, but without a navigation menu.
|
||||
|
||||
**[PICEA]** So, using this code:
|
||||
|
||||
*path/home-navless.phtml*
|
||||
```html
|
||||
{% extends "path/home" %}
|
||||
|
||||
{% section "header" %}{% endsection %}
|
||||
```
|
||||
|
||||
**[HTML]** Would render as such :
|
||||
```html
|
||||
<!DOCTYPE html>
|
||||
<html>
|
||||
<head>
|
||||
<meta charset="utf-8">
|
||||
<meta name="viewport" content="width=device-width, initial-scale=1">
|
||||
<title>Home page - AnExampleApp</title>
|
||||
</head>
|
||||
<body>
|
||||
<header id="header""></header>
|
||||
<main id="main">
|
||||
<h1>Welcome !</h1>
|
||||
|
||||
<article>
|
||||
This is our new blog ! We hope you are gonna enjoy your stay on our new platform !
|
||||
</article>
|
||||
</main>
|
||||
<footer id="footer">
|
||||
© Copyright 2022
|
||||
</footer>
|
||||
</body>
|
||||
</html>
|
||||
```
|
||||
|
||||
Notice that the `<header>` tag is now empty, since we've redeclared it in our navless view.

# Control structure - `function`
|
||||
|
||||
Sometimes comes a need to have a small subset of code which is gonna be used twice (or more)
|
||||
in the same view. Instead of simply duplicating the code (with everything that can then go wrong if you ever need
|
||||
to play with it later), you could create a `function`.
|
||||
|
||||
Functions are declared exactly like vanilla PHP.
|
||||
|
||||
**[PICEA]** So, using this code:
|
||||
|
||||
```html
|
||||
|
||||
{% use Psr\Http\Message\ServerRequestInterface %}
|
||||
|
||||
{% title "My generic title" %}
|
||||
|
||||
{% function printCustomTitle(ServerRequestInterface $request) : bool %}
|
||||
{% if $request->getAttribute('lean.route')->name === 'home' %}
|
||||
<h4 class="title">This is a custom title !</h4>
|
||||
|
||||
{% return true %}
|
||||
{% endif %}
|
||||
|
||||
{% return false %}
|
||||
{% endfunction %}
|
||||
|
||||
{% if ! printCustomTitle($request) %}
|
||||
<h1>{{ title() }}</h1>
|
||||
{% endif %}
|
||||
```
|
||||
|
||||
**[HTML]** Would yield:
|
||||
|
||||
*page **is** 'home'*
|
||||
```php
|
||||
<h4>This is a custom title !</h4>
|
||||
```
|
||||
|
||||
*page **is not** 'home'*
|
||||
```php
|
||||
<h4>My generic title</h4>
|

# Control structure - Loops
|
||||
|
||||
Picea's loop works the same as PHP original alternative syntax.
|
||||
|
||||
There is, however, some minors improvments and a new `{% or %}` clause working much like the `{% else %}` clause in a comparison.
|
||||
|
||||
## Loop using `for` / `or` / `continue` / `break` / `endfor`
|
||||
|
||||
The simplest of sequence loop, `for` / `endfor` simply iterate over a given counter (or whatever your needs).
|
||||
|
||||
**[PICEA]** So, using this code:
|
||||
|
||||
```html
|
||||
{% php $users = array_slice([ 'Tom', 'Sam', 'Mario', 'Steve' ], 0, random_int(0, 4)) %}
|
||||
|
||||
<h1>User list</h1>
|
||||
|
||||
<ul>
|
||||
{% for $i = 0; $i < count($users); $i++ %}
|
||||
{% if $users[$i] === 'Steve' %}
|
||||
{# Will leave the loop if user's name is Steve #}
|
||||
{% break %}
|
||||
{% else %}
|
||||
<li>{{ $users[$i] }}</li>
|
||||
{% endif %}
|
||||
{% or %}
|
||||
<li class="empty">Given user list was empty</li>
|
||||
{% endfor %}
|
||||
</ul>
|
||||
```
|
||||
|
||||
**[PHP]** Would compile like :
|
||||
|
||||
```php
|
||||
<?php $users = array_slice([ 'Tom', 'Sam', 'Mario', 'Steve' ], 0, random_int(0, 4)) ?>
|
||||
|
||||
<h1>User list</h1>
|
||||
|
||||
<ul>
|
||||
<?php for($i = 0; $i < count($users); $i++): ?><?php $for_a1kro2k2o = true;
|
||||
<?php if ($users[$i] === 'Steve'): ?>
|
||||
<?php break ?>
|
||||
<?php else: ?>
|
||||
<li><?php echo htmlspecialchars((string) $users[$i], 3, 'UTF-8', true) ?></li>
|
||||
<?php endif ?>
|
||||
<?php endfor ?><?php if (empty($for_a1kro2k2o)): ?><li class="empty">Given user list was empty</li><?php endif ?>
|
||||
</ul>
|
||||
```
|
||||
|
||||
**[HTML]** And would render as such given random_int() returns a **3**:
|
||||
|
||||
```html
|
||||
<h1>User list</h1>
|
||||
|
||||
<ul>
|
||||
<li>Tom</li>
|
||||
<li>Sam</li>
|
||||
<li>Mario</li>
|
||||
</ul>
|
||||
```
|
||||
|
||||
**[HTML]** Or would render as such given random_int() returns a **0**:
|
||||
|
||||
```html
|
||||
<h1>User list</h1>
|
||||
|
||||
<ul>
|
||||
<li class="empty">Tom</li>
|
||||
</ul>
|
||||
```
|
||||
|
||||
## Loop using `foreach` / `or` / `continue` / `break` / `endforeach`
|
||||
|
||||
The more complex `foreach` / `endforeach` allows to iterate over keys and values of an array.
|
||||
|
||||
**[PICEA]** So, using this code:
|
||||
```html
|
||||
{# Generate a random list of 0 to 4 names #}
|
||||
{% php $users = array_slice([ 'Tom', 'Sam', 'Mario', 'Steve', 'Joan' ], 0, random_int(0, 5)) %}
|
||||
|
||||
<h1>Random User list</h1>
|
||||
|
||||
<ul>
|
||||
{% foreach $users as $index => $name %}
|
||||
{% if $name === 'Steve' %}
|
||||
{# We skip Steve, but allows Joan #}
|
||||
{% continue %}
|
||||
{% endif %}
|
||||
<li>{{ $name }}</li>
|
||||
{% or %}
|
||||
<li class="empty">Given user list was empty</li>
|
||||
{% endforeach %}
|
||||
</ul>
|
||||
```
|
||||
|
||||
**[HTML]** Could render as such if prior random_int() returns '**2**':
|
||||
```html
|
||||
<h1>User list</h1>
|
||||
|
||||
<ul>
|
||||
<li>Tom</li>
|
||||
<li>Sam</li>
|
||||
</ul>
|
||||
```
|
||||
|
||||
**[HTML]** Could render as such given random_int() returns '**0**':
|
||||
```html
|
||||
<h1>User list</h1>
|
||||
|
||||
<ul></ul>
|
||||
```
|
||||
|
||||
## Loop using `while` / `or` / `continue` / `break` / `endwhile`
|
||||
|
||||
This syntax allows to loop on a computed iteration count.
|
||||
|
||||
**[PICEA]** So, using this code:
|
||||
|
||||
```html
|
||||
{% php $fruits = [ 'apple', 'pear', 'banana', 'tomato' ] %}
|
||||
|
||||
<h1>Grocery list</h1>
|
||||
|
||||
<ul>
|
||||
{% while $item = array_pop($fruits) %}
|
||||
<li>{{ ucfirst($item) }}</li>
|
||||
{% or %}
|
||||
<li class="empty">We should never see this, since the list is always populated !</li>
|
||||
{% endwhile %}

## Loop using `do` / `continue` / `break` / `while`
|

This syntax do not have an alternative syntax in vanilla PHP.

|

Picea allows for this unusual syntax to be used the same way you would with any other control structure.
|

There is, however, no support for the `or` clause for this structure since it will iterate at least once.

# Control structure - `Use`
|
||||
|
||||
While working with inside a template, it might be needed that you reference some other namespaces.
|
||||
|
||||
The use clause works exaclty like PHP's vanilla top of the page `use`.
|
||||
|
||||
**[PICEA]** So, using this code:
|
||||
|
||||
```html
|
||||
{% use AnyVendor\My\Super\Randomizer %}
|
||||
|
||||
{# One chance out of ten to end this loop %}
|
||||
{% while Randomizer::run(1, 10) === 10 %}
|
||||
{% if Randomizer::run(1, 100) < 50 %}
|
||||
<span>Lower than 50 !</span>
|
||||
{% else %}
|
||||
<strong>Greater than 50 !</strong>
|
||||
{% endif %}
|

{% endwhile %}
|
||||

<h4>DONE !</h4>

```

# Control structure - View (or `include`) / Block
|
||||
|
||||
There is three ways to include other views into your current view `{% view %} / {% include %}` or
|
||||
using `{% block %}{% endblock %}`.
|
||||
|
||||
The order of loading depends on the order given within your directory configuration; the first file found from it
|
||||
will be used.
|
||||
|
||||
## Inline `view` (string $path, array|null $arguments = null)
|
||||
|
||||
You must provide a valid `$path` from which the template will be loaded. If no `$arguments` are provided, defined
|
||||
variables from the caller's scope will be given (from `get_defined_vars()`).
|
||||
|
||||
**[PICEA]** So, using this code:
|
||||
|
||||
*path/base/nav.phtml*
|
||||
```html
|
||||
<nav>
|
||||
{% foreach $navigation as $index => $navItem %}
|
||||
{% view "path/base/nav-item", [ 'item' => $navItem, 'index' => $index] %}
|
||||
{% endforeach %}
|
||||
</nav>
|
||||
```
|
||||
|
||||
*path/base/nav-item.phtml*
|
||||
```html
|
||||
<a href="{{ $item->anchor }}" tabindex="{{ $index }}">{{ $item->name }}"</a>
|
||||
```
|
||||
|
||||
**[HTML]** Could render such as :
|
||||
```html
|
||||
<nav>
|
||||
<a href="#top">Top</a>
|
||||
<a href="#bottom">Bottom</a>
|
||||
<a href="#left">Left</a>
|
||||
<a href="#right">Right</a>
|
||||
</nav>
|
||||
```
|
||||
|
||||
## `include` (string $path) content from external file
|
||||
|
||||
Whenever you need to `include` a raw file from one of your view directories
|
||||
|
||||
## Reusable `block` (string $path, ...$arguments) / `endblock`
|
||||
|
||||
A better way to achieve this behaviour could be to create a `block` which you can define as needed.
|
||||
|
||||
**[PICEA]** So, using this code:
|
||||
|
||||
*path/base/nav.phtml*
|
||||
```html
|
||||
<nav>
|
||||
{% foreach $navigation as $index => $navItem %}
|
||||
{% block "path/base/nav-item-block", $navItem->name, $navItem->anchor, $index %}{% endblock %}
|
||||
{% endforeach %}
|
||||
</nav>
|
||||
```
|
||||
|
||||
*path/base/nav-item-block.phtml*
|
||||
```html
|
||||
{% arguments string $name, string $anchor, int $index = 0 %}
|
||||
|
||||
<a href="{{ $anchor }}" tabindex="{{ $index }}">{{ $name }}"</a>
|
||||
```
|
||||
|
||||
**[HTML]** Would render the same as the `view` example :
|
||||
```html
|
||||
<nav>
|
||||
<a href="#top">Top</a>
|
||||
<a href="#bottom">Bottom</a>
|
||||
<a href="#left">Left</a>
|
||||
<a href="#right">Right</a>
|
||||
</nav>
|
||||
```
|
||||
|
||||
### Extending a `block` using `define` and `slot`
|
||||
|
||||
You might need to define some custom content inside of a `block`.
|
||||
|
||||
You can do so by using `define` and `slot`.
|
||||
|
||||
**[PICEA]** So, using this code:
|
||||
|
||||
*path/base/nav.phtml*
|
||||
```html
|
||||
<nav>
|
||||
{% foreach $navigation as $index => $navItem %}
|
||||
{% block "path/base/nav-item-block", $navItem->name, $navItem->anchor, $index %}
|
||||
{% slot "attributes" %} class="nav-item" href="{{ $anchor }}" {% endslot %}
|
||||
{% endblock %}
|
||||
{% endforeach %}
|
||||
</nav>
|
||||
```
|
||||
|
||||
*path/base/nav-item-block.phtml*
|
||||
```html
|
||||
{% arguments string $name, string $anchor, int $index = 0 %}
|
||||
|
||||
{% define slot %}
|
||||
|
||||
<a {% slot "attributes" %}href="{{ $anchor }}" tabindex="{{ $index }}"{% endslot %}>{{ $name }}"</a>
|
||||
```
|
||||
|
||||
**[HTML]** Would render the same as the `view` example :
|
||||
```html
|
||||
<nav>
|
||||
<a href="#top">Top</a>
|

|

<a href="#left">Left</a>
|
||||
<a href="#right">Right</a>
