feature_request(paths): absolute paths support

[Kristinita]

@phbernard, ping.

1. Summary

If iconsPath is absolute path to site root:

    it would be nice if RealFaviconGenerator will not inject into HTML these lines:

<link rel="shortcut icon" href="https://kristinita.netlify.app/favicon.ico">
<meta name="msapplication-config" content="https://kristinita.netlify.app/browserconfig.xml">

2. Argumentation

Developers may prefer absolute links to relative. I always use absolute paths, so that other developers can use my sources without additional difficulties. As Philippe Bernard wrote on Stack Overflow relative and absolute paths both work.

But if the value of iconsPath key is absolute path, not /, RealFaviconGenerator inject to HTML files 2 additional lines. In the same time RealFaviconGenerator FAQ says that favicon.ico shouldn’t be declared in HTML, but if I use absolute path as value of iconsPath key, it declared.

3. Data

This is the configuration for Grunt, but my issue is relevant for another RealFaviconGenerator implementations as well.

My real realFavicon.coffee.

4. Behavior

4.1. Absolute paths

Part of my realFavicon.coffee:

iconsPath: "https://kristinita.netlify.app"

or, for example, it may be:

iconsPath: "<%= templates.yamlconfig.SITEURL %>"

Where <%= templates.yamlconfig.SITEURL %> is Grunt template for absolute path to head page my site.

RealFaviconGenerator inject to HTML:

<link rel="apple-touch-icon" sizes="180x180" href="https://kristinita.netlify.app/apple-touch-icon.png">
<link rel="icon" type="image/png" sizes="32x32" href="https://kristinita.netlify.app/favicon-32x32.png">
<link rel="icon" type="image/png" sizes="16x16" href="https://kristinita.netlify.app/favicon-16x16.png">
<link rel="manifest" href="https://kristinita.netlify.app/site.webmanifest">
<link rel="mask-icon" href="https://kristinita.netlify.app/safari-pinned-tab.svg" color="darkorange">
<link rel="shortcut icon" href="https://kristinita.netlify.app/favicon.ico">
<meta name="apple-mobile-web-app-title" content="Kristinita&rsquo;s Search">
<meta name="application-name" content="Kristinita&rsquo;s Search">
<meta name="msapplication-TileColor" content="darkorange">
<meta name="msapplication-TileImage" content="https://kristinita.netlify.app/mstile-144x144.png">
<meta name="msapplication-config" content="https://kristinita.netlify.app/browserconfig.xml">
<meta name="theme-color" content="#ffffff"></head>

2 unexpected lines:

<link rel="apple-touch-icon" sizes="180x180" href="https://kristinita.netlify.app/apple-touch-icon.png">
<link rel="icon" type="image/png" sizes="32x32" href="https://kristinita.netlify.app/favicon-32x32.png">
<link rel="icon" type="image/png" sizes="16x16" href="https://kristinita.netlify.app/favicon-16x16.png">
- <link rel="manifest" href="https://kristinita.netlify.app/site.webmanifest">
<link rel="mask-icon" href="https://kristinita.netlify.app/safari-pinned-tab.svg" color="darkorange">
<link rel="shortcut icon" href="https://kristinita.netlify.app/favicon.ico">
<meta name="apple-mobile-web-app-title" content="Kristinita&rsquo;s Search">
<meta name="application-name" content="Kristinita&rsquo;s Search">
<meta name="msapplication-TileColor" content="darkorange">
<meta name="msapplication-TileImage" content="https://kristinita.netlify.app/mstile-144x144.png">
- <meta name="msapplication-config" content="https://kristinita.netlify.app/browserconfig.xml">
<meta name="theme-color" content="#ffffff"></head>

4.2. Relative paths

If:

- iconsPath: "https://kristinita.netlify.app"
+ iconsPath: "/"

RealFaviconGenerator inject relative paths without shortcut icon and msapplication-config.

<link rel="apple-touch-icon" sizes="180x180" href="/apple-touch-icon.png">
<link rel="icon" type="image/png" sizes="32x32" href="/favicon-32x32.png">
<link rel="icon" type="image/png" sizes="16x16" href="/favicon-16x16.png">
<link rel="manifest" href="/site.webmanifest">
<link rel="mask-icon" href="/safari-pinned-tab.svg" color="darkorange">
<meta name="apple-mobile-web-app-title" content="Kristinita&rsquo;s Search">
<meta name="application-name" content="Kristinita&rsquo;s Search">
<meta name="msapplication-TileColor" content="darkorange">
<meta name="msapplication-TileImage" content="/mstile-144x144.png">
<meta name="theme-color" content="#ffffff">

4.3. Desired

Absolute paths without shortcut icon and msapplication-config.

<link rel="apple-touch-icon" sizes="180x180" href="https://kristinita.netlify.app/apple-touch-icon.png">
<link rel="icon" type="image/png" sizes="32x32" href="https://kristinita.netlify.app/favicon-32x32.png">
<link rel="icon" type="image/png" sizes="16x16" href="https://kristinita.netlify.app/favicon-16x16.png">
<link rel="manifest" href="https://kristinita.netlify.app/site.webmanifest">
<link rel="mask-icon" href="https://kristinita.netlify.app/safari-pinned-tab.svg" color="darkorange">
<meta name="apple-mobile-web-app-title" content="Kristinita&rsquo;s Search">
<meta name="application-name" content="Kristinita&rsquo;s Search">
<meta name="msapplication-TileColor" content="darkorange">
<meta name="msapplication-TileImage" content="https://kristinita.netlify.app/mstile-144x144.png">
<meta name="theme-color" content="#ffffff"></head>

5. Possible solution

For example, key root.

If:

root: true

RealFaviconGenerator will not inject msapplication-config and shortcut icon links to HTML files whatever the value of the iconsPath key.

Thanks.
