Optimize jpeg images using assetic from css file instead of image tag -

-

the article below i'm trying do, instead of working on <img> tags want work references made in css well, background-image:url('someimage.jpg'); make optimizing hundreds of images have on website far faster manually doing , more convenient.

for example documentation how using twig templating engine.

{% image '@appbundle/resources/public/images/example.jpg'     filter='jpegoptim' output='/images/example.jpg' %}     <img src="{{ asset_url }}" alt="example"/> {% endimage %}

is possible assetic , jpegoptim (or through other solution)

http://symfony.com/doc/current/cookbook/assetic/jpeg_optimize.html

your best bet, honestly, write script jpegoptim existing files.

it's possible want creating new assetic filter, if want save jpegs different location (what using image tag filter now), little detail looks it'd quite hard. if used filter find , rewrite images in-place, have big clunky version of script find , optimize images, , it's fair bit of work not gain.

Decoding a Python 2 `tempfile` with python-future -

i'm attempting write python 2/3 compatible routine fetch csv file, decode latin_1 unicode , feed csv.dictreader in robust, scalable manner. for python 2/3 support, i'm using python-future including imporing open builtins , , importing unicode_literals consistent behaviour i'm hoping handle exceptionally large files spilling disk, using tempfile.spooledtemporaryfile i'm using io.textiowrapper handle decoding latin_1 encoding before feeding dictreader this works fine under python 3. the problem textiowrapper expects wrap stream conforms bufferediobase . unfortunately under python 2, although have imported python 3-style open , vanilla python 2 tempfile.spooledtemporaryfile still of course returns python 2 cstringio.stringo , instead of python 3 io.bytesio required textiowrapper . i can think of these possible approaches: wrap python 2 cstringio.stringo python 3-style io.bytesio . i'm not sure how approach - need write such wrapper or 1 ex
