https://poly-style.appspot.com is a web service to wrap existing stylesheets with Polymer's style module system.
Example - load a stylesheet
<head>
<link rel="import" href="bower_components/polymer/polymer.html">
<link rel="import" href="https://poly-style.appspot.com?url=https://example.com/styles.css">
<style is="custom-style" include="shared-styles"></style>
</head>By default, the id "shared-styles" is used on the dom-module wrapper (e.g. <dom-module id="shared-styles">). You can change this with the id URL param. See example below.
Example - use a custom id
<head>
<link rel="import" href="bower_components/polymer/polymer.html">
<link rel="import" href="https://poly-style.appspot.com?id=theme-styles&url=https://example.com/styles.css">
<style is="custom-style" include="theme-styles"></style>
</head>Example - element that uses a shared style
<link rel="import" href="../polymer/polymer.html">
<link rel="import" href="https://poly-style.appspot.com?id=material-styles&url=https://example.com/styles.css">
<dom-module id="my-element">
<template>
<style include="material-styles">
/* Optional - define extra styles using the same <style> tag. */
:host {
display: block;
}
</style>
...
</template>
<script>
Polymer({is: 'my-element'});
</script>
</dom-module>Example - wrapping css text
<link rel="import" href="https://poly-style.appspot.com?styles=%3Ahost%7Bdisplay%3Ablock%3B%7D">
produces:
<dom-module id="shared-styles">
<template>
<style>
:host{display:block;}
</style>
</template>
</dom-module>Note: the url parameter trumps the style parameter if both are used together.
Install the webtest framework:
pip install WebTest
In the main project folder, run the rest runner:
python testrunner.py ~/google-cloud-sdk test/
The first argument is the location of your App Engine SDK. The second argument is the path to the test folder.
