/README.textile:
--------------------------------------------------------------------------------
1 | h2. Introduction
2 |
3 | SSBX provides a stupidly simple API for supporting Single Site Browsers (SSB) in your website.
4 |
5 | The current version is a basic implementation to test out the feasibility of the concept, and explore how to make a consistent unified API across platforms.
6 |
7 | h3. Examples
8 |
9 |
10 | if (SSBX.isAvailable()) {
11 | SSBX.log('hello');
12 | SSBX.notify({ message: 'This is a message', title: 'Title' });
13 | SSBX.notifyOnce({ message: 'This is a message', title: 'Title', unique_id: 5});
14 | SSBX.setDockBadge(5);
15 | SSBX.log(SSBX.availableDriver);
16 | }
17 |
22 | SSBX.run(function() {
23 | SSBX.log('hello');
24 | }
25 | SSBX.notify({ message: 'This is a message', title: 'Title' })
41 |
42 | Show a notification and log it so it doesn't get displayed again. Logs to a cookie:
43 |
44 | SSBX.notifyOnce({ unique_id: 1, message: 'This is a message', title: 'Title' })
45 |
46 | SSBX expects a unique integer ID for messages to be handled this way.
47 |
48 | h3. Dock badge icons
49 |
50 | Only available in Mac OS (until someone offers a Windows equivalent):
51 |
52 | SSBX.setDockBadge(3)
53 |
54 | h3. Console logging
55 |
56 | To make it easier to debug your JavaScript from within an SSB you can use unified console logging:
57 |
58 | SSBX.log('Message')
59 |
60 | h3. Capabilities
61 |
62 | * Test if the SSB is available: SSBX.isAvailable()
63 | * Check which SSB is active: SSBX.availableDriver
64 |
65 | h3. Drag and drop
66 |
67 | h2. Running tests
68 |
69 | Run tests inside the appropriate SSB. There's tests for Bubbles and Fluid.
70 |
71 | h2. Library style
72 |
73 | I've added semicolons to line endings to make compressing/obscuring the library easier (if you do that sort of thing).
