+# 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>
+```

+# 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 }}

+
+## Using string format variant `printf` / `printf.raw`
+
+Those tokens represents the equivalent of the printf() function from PHP.

+
+```html
+{% php 
+    $num = 5;

+# 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'; ?>

+    <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 $selected = random_int(0,5) %}
+
+{% switch $selected %}

+```
+
+**[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="#bottom">Bottom</a>
+    <a href="#left">Left</a>
+    <a href="#right">Right</a>
+</nav>
