why not use something like "1.*" ?

---------------------------------------------------------------------------

by fabpot at 2012-05-26T05:55:16Z

This is just an example and we are not going to update it with each new release. So, we can either use `1.*` as suggested by @lyrixx or/and add a note referring to the Composer docs.

Discussion
----------

Add abs filter to Twig

With abs it is possible to make negative values positive and leave positive values positive.

---------------------------------------------------------------------------

by maartendekeizer at 2012-05-26T19:02:34Z

Example when using abs

{% if days_left < 0 %}
    {{ days_left|abs }} days to late!
{% else %}
    {{ days_left }} days left
{% endif %}

I'm not sure about adding this filter in the core. I think it would be better in the Twig-extensions repo. @fabpot thoughts ?

---------------------------------------------------------------------------

by maartendekeizer at 2012-05-26T21:18:47Z

@stof abs is a really basic/natural function it belongs to the base mathematic functions. If this was an implementation of for example the ABC-formula or Pythagoras it must be in the extension repo., but abs is more core related I think.

Can you add some unit tests and squash your commits? Thanks.

---------------------------------------------------------------------------

by maartendekeizer at 2012-05-27T14:40:56Z

First time squashing commits; learned something new :-). I will add a unit test tomorrow.

---------------------------------------------------------------------------

by maartendekeizer at 2012-05-27T17:36:58Z

Unit test and documentation added.

---------------------------------------------------------------------------

by fabpot at 2012-05-27T18:41:25Z

After fixing the markup issue, you will have to squash again ;)

---------------------------------------------------------------------------

by maartendekeizer at 2012-05-27T20:44:29Z

Done

---------------------------------------------------------------------------

by fabpot at 2012-05-28T19:19:55Z

Looks like you have not squash your commits.

---------------------------------------------------------------------------

by maartendekeizer at 2012-05-28T20:05:34Z

@fabot you want one commit for the complete pr?

---------------------------------------------------------------------------

by fabpot at 2012-05-28T20:06:53Z

For such a PR, yes.
