Outlook can sometimes add a bit of spacing on the left and right side of a element that can cause some layout-related headaches. By using the vendor-specific mso-table-lspace and mso-table-rspace CSS properties, you can be rid of those spaces and continue on to tackle the million other problems cau...
More than one queue may be created. Each queue can be thought of as a separate branch.
hg qqueue --create foo // Create a new queue called "foo"

Functional tests are best described as tests for your user stories. If you've dealt with user stories before they normally follow the following pattern:
As a [role], I want to [desire], so that [benefit/desired outcome]

If we want to test JavaScript on a website, we'll need to use something a bit more powerful than Goutte (which is just cURL via Guzzle). There are a couple of options such as ZombieJS, Selenium and Sahi. For this example I'll use Selenium.

Django 1.10 introduced a new middleware style where process_request and process_response are merged together.

DateTimeField is used to store date time values.
class MyModel(models.Model):
start_time = models.DateFimeField(null=True, blank=True)
created_on = models.DateTimeField(auto_now_add=True)

A global RegExp match can be performed using preg_match_all. preg_match_all returns all matching results in the subject string (in contrast to preg_match, which only returns the first one).
The preg_match_all function returns the number of matches. Third parameter $matches will contain matches in f...
The predicate function matches can be used to evaluate strings on the fly without use of any object declarations.
IF matches( val = 'Not a hex string'
regex = '[0-9a-f]*' ).
cl_demo_output=>display( 'This will not display' ).
ELSEIF matches( val = '6c6f7665'

}

Unlike most other JavaScript objects, symbols are not automatically converted into a string when performing concatenation.
let apple = Symbol('Apple') + ''; // throws TypeError!
Instead, they have to be explicitly converted into a string when necessary, (for example, to get a textual description...
