Audiomanager for text-to-speech cloud services

I have been working on a project , that relies on text-to-speech cloud services for a lot of things.

Audiomanager abstracts access to popular text-to-speech cloud services like Google, Ivona, Amazon Polly… Really a timesaver, when evaluating different services.

Polly Example

$adapter = new \AudioManager\Adapter\Polly();
$adapter->getOptions()->initialize()
    ->setVersion('latest')
    ->setRegion('us-west-2')
    ->setCredentials()
        ->setKey('...')
        ->setSecret('...');

$adapter->getOptions()->setOutputFormat('...'); //Default 'mp3'
$adapter->getOptions()->setLexiconNames('...');
$adapter->getOptions()->setSampleRate('...'); //Default '16000'
$adapter->getOptions()->setTextType('...'); //Default 'text'
$adapter->getOptions()->setVoiceId('...'); //Default 'Salli'

$adapter = new \AudioManager\Adapter\Polly();

$adapter->getOptions()->initialize()

->setVersion('latest')

->setRegion('us-west-2')

->setCredentials()

->setKey('...')

->setSecret('...');

$adapter->getOptions()->setOutputFormat('...'); //Default 'mp3'

$adapter->getOptions()->setLexiconNames('...');

$adapter->getOptions()->setSampleRate('...'); //Default '16000'

$adapter->getOptions()->setTextType('...'); //Default 'text'

$adapter->getOptions()->setVoiceId('...'); //Default 'Salli'

Cleaning up the WordPress Feed (Validation)

When using your main content feed to share posts via buffer or other services, it is crucial that your feed validates cleanly.

There are always things in the generated WordPress content that can break your feed validation. Here some things to cleanup or alter your delivered feed content.

CONDITIONAL TAGS

is_feed()
Check for syndication request. This tag is not typically used by users; it is used internally by WordPress and is available for Plugin Developers.

Check for feed syndication in your themes functions.php

if (is_feed()) {
    /.. tweaks go here ../
}

if (is_feed()) {

/.. tweaks go here ../

}

REMOVE IFRAMES

function rss_noiframe($content) {
        
    $content = preg_replace( '/<iframe(.*)\/iframe>/is', '', $content );

    return $content;
}

add_filter('the_excerpt_rss', 'rss_noiframe');
add_filter('the_content_feed', 'rss_noiframe');

function rss_noiframe($content) {

$content = preg_replace( '/<iframe(.*)\/iframe>/is', '', $content );

return $content;

}

add_filter('the_excerpt_rss', 'rss_noiframe');

add_filter('the_content_feed', 'rss_noiframe');

REMOVE / DISABLE COMMENTS

function rss_nocomments($content) {
    
     global $post;
      $post->comment_status="closed";
   
  
}

add_filter('the_excerpt_rss', 'rss_nocomments');
add_filter('the_content_feed', 'rss_nocomments');

function rss_nocomments($content) {

global $post;

$post->comment_status="closed";

}

add_filter('the_excerpt_rss', 'rss_nocomments');

add_filter('the_content_feed', 'rss_nocomments');

REMOVE RESPONSIVE IMAGES

The sizes attribute breaks feed validation, here how to clean it up.

function no_responsive_image_feeds() {
    add_filter( 'max_srcset_image_width', function() {
       return 1;
    } );
}

add_action('rss2_head', 'no_responsive_image_feeds' );
add_action('atom_head', 'no_responsive_image_feeds' );
add_action('rss_head', 'no_responsive_image_feeds' );

function no_responsive_image_feeds() {

add_filter( 'max_srcset_image_width', function() {

return 1;

} );

}

add_action('rss2_head', 'no_responsive_image_feeds' );

add_action('atom_head', 'no_responsive_image_feeds' );

add_action('rss_head', 'no_responsive_image_feeds' );

INCLUDE PAGES IN POST FEED

if (is_feed()) {
function feedFilter($query) {
	if ($query->is_feed) {
		$query->set('post_type','any');
		}
	return $query;
}
add_filter('pre_get_posts','feedFilter');
}

if (is_feed()) {

function feedFilter($query) {

if ($query->is_feed) {

$query->set('post_type','any');

}

return $query;

}

add_filter('pre_get_posts','feedFilter');

}

ADJUST AMOUNT OF POSTS

if (is_feed()) {

function feedFilter($query) {
	if ($query->is_feed) {
		$query->set('posts_per_page','11');
	}
 
	return $query;
}
add_filter('pre_get_posts','feedFilter');

}

if (is_feed()) {

function feedFilter($query) {

if ($query->is_feed) {

$query->set('posts_per_page','11');

}

return $query;

}

add_filter('pre_get_posts','feedFilter');

}

LIMIT BY CATEGORY

if (is_feed()) {
function feedFilter($query) {
	if ($query->is_feed) {
		$query->set('category_name', 'my-special-cat');
	}
 
	return $query;
}
add_filter('pre_get_posts','feedFilter');
}

if (is_feed()) {

function feedFilter($query) {

if ($query->is_feed) {

$query->set('category_name', 'my-special-cat');

}

return $query;

}

add_filter('pre_get_posts','feedFilter');

}

Using SQLite in Javascript with sql.js

Fun Fun Fun :)

var sql = require('sql.js');
// or sql = window.SQL if you are in a browser

// Create a database
var db = new sql.Database();
// NOTE: You can also use new sql.Database(data) where
// data is an Uint8Array representing an SQLite database file

// Execute some sql
sqlstr = "CREATE TABLE hello (a int, b char);";
sqlstr += "INSERT INTO hello VALUES (0, 'hello');"
sqlstr += "INSERT INTO hello VALUES (1, 'world');"
db.run(sqlstr); // Run the query without returning anything

var res = db.exec("SELECT * FROM hello");
/*
[
	{columns:['a','b'], values:[[0,'hello'],[1,'world']]}
]
*/

// Prepare an sql statement
var stmt = db.prepare("SELECT * FROM hello WHERE a=:aval AND b=:bval");

// Bind values to the parameters and fetch the results of the query
var result = stmt.getAsObject({':aval' : 1, ':bval' : 'world'});
console.log(result); // Will print {a:1, b:'world'}

// Bind other values
stmt.bind([0, 'hello']);
while (stmt.step()) console.log(stmt.get()); // Will print [0, 'hello']

// You can also use javascript functions inside your SQL code

// free the memory used by the statement
stmt.free();
// You can not use your statement anymore once it has been freed.
// But not freeing your statements causes memory leaks. You don't want that.

Font Face Observer … gives you a font promise ;)

Font Face Observer

is a fast and simple web font loader. You can use it to load fonts and customise your browser’s font loading behaviour.

Font Face Observer gives you control over web font loading using a simple promise based interface. It doesn’t matter where your fonts come from: host them yourself, or use a web font service such as Google Fonts, Adobe Typekit, Fonts.com and Webtype.

var font = new FontFaceObserver('My Family', {
  weight: 400
});

font.load().then(function () {
  console.log('Font is available');
}, function () {
  console.log('Font is not available');
});

var font = new FontFaceObserver('My Family', {

weight: 400

});

font.load().then(function () {

console.log('Font is available');

}, function () {

console.log('Font is not available');

});

Easy leaderlines for your webpage

Quickly draw a leader line in your web page.

<div id="start">start</div>
<div id="end">end</div>

1 2	<div id="start">start</div> <div id="end">end</div>

// Add new leader line from `start` to `end` (HTML/SVG elements, basically).
new LeaderLine(
  document.getElementById('start'),
  document.getElementById('end')
);

// Add new leader line from `start` to `end` (HTML/SVG elements, basically).

Lets fix the short comings of current CSS integrations – EQCSS / Element queries

“Element queries are a new way of thinking about responsive web design where the responsive conditions apply to elements on the page instead of the width or height of the browser.
Unlike CSS @media queries, @element Queries are aware of more than just the width and height of the browser, you can write responsive conditions for a number of different situations like how many characters of text or child elements an element contains.
Another concept that element queries brings to CSS is the idea of ‘scoping’ your styles to one element in the same way that JavaScript functions define a new scope for the variables they contain.”
