We create an index with:

• two filters: synonyms_expand and synonyms_contract
• two analyzers: synonyms_expand and synonyms_contract
• three text fields:
  • text_1 uses the synonyms_expand analyzer at index and search time
  • text_2 uses the synonyms_expand analyzer at index time, but the standard analyzer at search time
  • text_3 uses the synonyms_contract analyzer at index and search time

Better Jasmine Tests With this

On the Refinery29 Mobile Web Team, codenamed "Bicycle", all of our unit tests are written using Jasmine, an awesome BDD library written by Pivotal Labs. We recently switched how we set up data for tests from declaring and assigning to closures, to assigning properties to each test case's this object, and we've seen some awesome benefits from doing such.

The old way

Up until recently, a typical unit test for us looked something like this:

describe('views.Card', function() {

thijsc

def select_from_chosen(item_text, options)
  field = find_field(options[:from])
  option_value = page.evaluate_script("$(\"##{field[:id]} option:contains('#{item_text}')\").val()")
  page.execute_script("$('##{field[:id]}').val('#{option_value}')")
end

# Capistrano task to upload configuration files outside SCM
# Jesus Burgos Macia
#
# This allows us to have server's config files isolated from development ones.
# That's useful for several reasons, but the most important is that you can
# ignore files from repository.
#
# The task will upload all files found in

Load GitHub Gists asynchronously

This is now a Bower package: [gist-async]. [gist-async]: https://github.com/razor-x/gist-async

Requires jQuery.

Jekyll plugin included that modifies the gist markup added by its gist Liquid tag.

Load GitHub Gists asynchronously and optionally specify which file to show.

Notes
=====
Labels: On the label you should put a "for" attribute if you're not using something like simple_form
This helps capybara to find your field
e.g. <label for="my_field_id">Some label</label>
=end

field = "Label on my field"
value = "existing option in list"

Aspirational Dropbox SCSS Principles

This is purposefully ambitious and aspirational. Some concepts that are worth understanding in addition to the principles outlined here include:

• Object-Oriented CSS
• BEM naming methodology
• CSS Namespacing

Here’s a CodePen I’ll periodically update with the compiled CSS to use as a testing playground.

module SortablePaginator
    # provides helpful metrics for the paginator and mustache templates

      paginator_sort = config["paginator"]["sort"] rescue 'desc'
      current_page   = master.page_data['current_page'].to_i
      post_count     = all.length
      page_count     = (post_count.to_f/per_page).ceil

      if paginator_sort == 'asc'
