Share Counts

I have always struggled with getting all the various share buttons from Facebook, Twitter, Google Plus, Pinterest, etc to align correctly and to not look like a tacky explosion of buttons. Seeing a number of sites rolling their own share buttons with counts, for example The Next Web I decided to look into the various APIs on how to simply return the share count.

If you want to roll up all of these into a single jQuery plugin check out Sharrre

Many of these API calls and methods are undocumented, so anticipate that they will change in the future. Also, if you are planning on rolling these out across a site I would recommend creating a simple endpoint that periodically caches results from all of the APIs so that you are not overloading the services will requests.

Creating a new Rails app with Rspec, Backbone, Jasmine

NOTE: This guide assumes that you already have ruby, rails, and mysql installed on your machine, and have an IDE or code editing tool (VIM!) all ready to go.

Creating the app

First thing's first. Rails makes it nice and simple to create a new app with the proper directory structure (lets assume we are calling this app “luna” and our directory with projects is “projects”):

$ cd projects
$ rails new luna

      function truncText (text, maxLength, ellipseText){
        ellipseText = ellipseText || '…';
       
        if (text.length < maxLength) 
            return text;

        //Find the last piece of string that contain a series of not A-Za-z0-9_ followed by A-Za-z0-9_ starting from maxLength
        var m = text.substr(0, maxLength).match(/([^A-Za-z0-9_]*)[A-Za-z0-9_]*$/);
        if(!m) return ellipseText;

Finally, Simple Form support Boostrap 3. 👏

But I found it still dosen't support some components in Bootstrap 3. Or may be in the future. But I can't wait, so I find a solution to support them. It was inspired by heartcombo/simple_form#531 (comment) .

This is a final solution and I used in my project.

Elixir installation guide

Version numbers should be the ones you want. Here I do it with the last ones available at the moment of writing.

The simplest way to install elixir is using your package manager. Sadly, at the time of writing only Fedora shows the intention to keep its packages up to date. There you can simply sudo dnf install erlang elixir and you are good to go.

Anyway, if you intend to work with several versions of erlang or elixir at the same time, or you are tied to a specific version, you will need to compile it yourself. Then asdf is your best friend.

// Examples

// Yes, "router.router" twice - this assumes that the router is being injected
// into the component. Otherwise lookup 'router:main'
// One of these will be of interest, figure out which one you want:
this.get('router.router.state');
this.get('router.router.state.params');

this.get('container').lookup('controller:application').currentPath;
