Dancer::Plugin::FontSubset - Generate font subsets on-the-fly
In the app:
in the template:
*Dancer::Plugin::FontSubset* generate subsets of the glyphs of given
fonts, a little like what Google Font provides
. Currently, *Dancer::Plugin::FontSubset* only works for a subset
TTF fonts. Always test that any given font will work well with the
plugin before throwing it in a production system.
to use this plugin, put your fonts in the directory "public/fonts". The
original font file can be accessed via the url "/fonts/thefont.tff"
(natch), and its subsets via the route "/font/thefont.ttf?t=abc", where
the characters to be included in the subset are passed via the *t*
parameter. For example, the url required to generate the font subset
required to render 'Hello world' would be
"/font/thefont.ttf?t=%20Helowrd" (including the whitespace (%20) is
important, as it is often a glyph by its own right).
JQuery Helping Script
A JQuery utility script is also available at "/font/subset.js". If the
script is loaded by a page, it will find all elements having the
*subfont* class, generate the characters required and query the
application for the subset of whichever font provided in the *data-font*
attribute. In other words,
is all that is required to have the "h1" element of this document
rendered using the appropriate subset of the "my_font.ttf" font.
To improve performance you can enable caching, which will use
Dancer::Plugin::Cache::CHI to cache the generated font subsets.
The system directory containing the fonts. Defaults to "public/fonts".
The root route for the subset fonts. Defaults to "/font".
Boolean indicating if caching should be used. Defaults to *false*. If
set to true, the application will also use Dancer::Plugin::Cache::CHI.
