        "description": "# lens\n\n`lens` is a command line tool for easy traversal and\npretty printing fo data structures from the terminal.\nIt is extensible.\n\nUses the great [Pygments](http://pygments.org/) library.\n\nIt should work on both Python 2 and 3, but was developed\nwith Python 3 in mind.\n\n## Installation\n\nThe package is yet registered to PyPI. That means you should\nbe able to install it with pip. `lens` was already taken, so\nwe used `lens-cli`.\n\n```\npip install lens-cli\n```\n\n## Usage\n\nCalling `lens -h` will print this message:\n\n```\nusage: lens [-h] [--input INPUT] [--format FORMAT]\n            [--no-highlight NO_HIGHLIGHT]\n            [key [key ...]]\n\nExtensible data structure traversal from the command line\n\npositional arguments:\n  key                   the keys to traverse\n\noptional arguments:\n  -h, --help            show this help message and exit\n  --input INPUT, -i INPUT\n                        the input file (defaults to the standard input)\n  --format FORMAT, -f FORMAT\n                        the data format to consume (defaults to json)\n  --no-highlight NO_HIGHLIGHT, -n NO_HIGHLIGHT\n                        prevent syntax highlighting\n```\n\nThis should be relatively straightforward. Let's go through a few examples:\n\n```bash\n# just calling lens will print everything, syntax-highlighted\n$ curl -s https://httpbin.org/get | lens\n{\n  \"args\": {}, \n  \"headers\": {\n    \"Accept\": \"text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8\", \n    \"Accept-Encoding\": \"gzip, deflate, br\", \n    \"Accept-Language\": \"de,en-US;q=0.7,en;q=0.3\", \n    \"Dnt\": \"1\", \n    \"Host\": \"httpbin.org\", \n    \"Referer\": \"https://httpbin.org/\", \n    \"Upgrade-Insecure-Requests\": \"1\", \n    \"User-Agent\": \"Mozilla/5.0 (Macintosh; Intel Mac OS X 10.11; rv:50.0) Gecko/20100101 Firefox/50.0\"\n  }, \n  \"origin\": \"213.61.134.12\", \n  \"url\": \"https://httpbin.org/get\"\n}\n\n# suppose we only want to see the \"Host\" header\n$ curl -s https://httpbin.org/get | lens header Host\n\"httpbin.org\"\n\n# or use xml\n$ curl -s https://httpbin.org/xml | lens -f=xml\n<slideshow \n    title=\"Sample Slide Show\"\n    date=\"Date of publication\"\n    author=\"Yours Truly\"\n    >\n    <slide type=\"all\">\n      <title>Wake up to WonderWidgets!</title>\n    </slide>\n    <slide type=\"all\">\n        <title>Overview</title>\n        <item>Why <em>WonderWidgets</em> are great</item>\n        <item/>\n        <item>Who <em>buys</em> WonderWidgets</item>\n    </slide>\n</slideshow>\n\n# suppose we want to only get the title of the second slide\n$ curl -s https://httpbin.org/xml | lens -f=xml slide 1 title\n<title>Overview</title>\n```\n\nWe can also read from files by providing an `-i` option.\nlens also discovers if its output is redirected to a file, in which case\nno syntax highlighting will be applied (the same can be achieved through\nthe `--no-highlighting/-n` option).\n\n## Extending\n\nYou can write your own parsers/traversers - admittedly, parsers\nis not a great name, but for now we stick with it.\n\nThey should inherit from `LensParser` in `lens.parsers.base`,\nand at least implement the method `treat(self, inpt, keys)`,\nwhere `inpt` is the input string and `keys` are the keys to\ntraverse. It should return the traversed data structure as a\nstring.\n\nOptionally, the parser can specify a Pygments lexer by exposing\nthe static attribute `lexer`, if highlighting is applicable. It\nwill work without one, though.\n\nThe plugins can be third party `pip` modules, in which case they\nshould follow the naming scheme `lens-{format-name}` and export\nthe parser under the name `Parser`.\n\nAn example of a plugin can be found in the\n[bson](https://github.com/port-zero/lens_bson) parser repository.\n\nThat is all you need to know!\n\n<hr/>\n\nHave fun!",
