        "description": "# css-class-names [![Build Status](https://travis-ci.org/arturfsousa/css-class-names.svg?branch=master)](https://travis-ci.org/arturfsousa/css-class-names)\n\nA python script for css class names conditional generation. Inspered by the node package [classnames](https://github.com/JedWatson/classnames).\n\n## Why?\n\nThe node `classnames` package has been helping me a lot with `React/JSX` and general javascript front-end development. I really missed something similar to use when working with `django` and `jinja2` templates, so, I decided to create this package.\n\n## Usage\n\nYou can add css class names by calling the function with arguments as:\n\n* Strings\n* Numbers: Floats or Integers (0 is allowed)\n* Sequences: Lists or Tuples\n* Dictionaries\n\n```python\nfrom css_class_names import class_names\n\nclass_names('header', 'is-visible') # 'header is-visible'\nclass_names(['is-visible', 'text-uppercase']) # 'is-visible text-uppercase'\nclass_names((100001000, 'clear')) # '100001000 clear'\n\nclass_names('header', { \n    'header--is-fixed': True, \n    'header--is-blue': False \n}) \n# 'header header--is-fixed'\n```\n\n### Conditional dicts\n\nDictionaries can be used to concat class names conditionally using expressions:\n\n```python\nfrom css_class_names import class_names\n\nerrors = ['Some error']\nclass_names('alert', { \n    'alert-danger': errors, \n    'alert-success': not errors,\n    'small': True\n}) \n# 'alert alert-danger'\n\nclass_names('client', { \n    'client-{}'.format(client.id): client, \n    'disable': not client.active()\n}) \n# 'client client-989'\n```\n\n### Excludes falsy values\n\nFalsy values (except 0) and not supported types will be ignored:\n\n```python\nfrom css_class_names import class_names\n\nclass_names([], '', False, {}, 0, object(), lambda x: x, None)\n# '0'\n```\n\n### Strip and flatten\n\nStrings are striped and sequences are recursively flattened:\n\n```python\nfrom css_class_names import class_names\n\nclass_names([' header   ', ['  green ', ' small ']])\n# 'header green small'\n```\n\n### Dedupe\n\nYou can dedupe names with the `dedupe` argument:\n\n```python\nfrom css_class_names import class_names\n\nclass_names('cart', 'is-open', 'is-logged', {'is-logged': True}, dedupe=True)\n# 'cart is-open is-logged'\n```\n\n### Prefix\n\nYou can add class name prefixes with the `prefix` argument. This is really usefull when you need a class namespace or using the [BEM](http://getbem.com/) methodology:\n\n```python\nfrom css_class_names import class_names\n\nclass_names('head', 'head--is-empty', {'head--is-large': True}, prefix='mysite-')\n# 'mysite-head mysite-head--is-empty mysite-head--is-large'\n```\n\n## Development\n\nAfter cloning the repository, create a virtualenv and use the `Makefile` commands to `setup` development requirements and run tests:\n\n```bash\nmake setup\nmake lint \nmake test \nmake watch # run tests when code changes\nmake coverage\n```\n\n\n",
