        "description": "=====\nPypit\n=====\n\nPypit (pronounce \"Pipe it!\") is a python library for building shell pipeline easily via configuration.\n\nThe principe is simple: create a configuration which describes a programmes list with all options and your done.\n\nExemple\n-------\n\nLet's say we have a `file.txt` with the following content::\n    \n    HellO\n    Foo\n    BAR\n    Bla\n\nThe following configuration will sort the `file.txt` and lower all capitalize chars::\n\n    >>> config = [\n    ...    {\n    ...        \"cmd\": \"sort -r {{input}}\",\n    ...    },\n    ...    {\n    ...        \"cmd\": \"tr A-Z a-z\",\n    ...        \"use_stdin\": True\n    ...    }\n    ...]\n\nTo process this configuration::\n\n    >>> from pypit import Pypit\n    >>> result = Pypit(config).run(file_name=\"file.txt\")\n    >>> print result\n    hello\n    foo\n    bla\n    bar\n\nExplanation\n-----------\n\nOnly `cmd` is required. This is the command line to use.\n\nIf `use_sdtin` is True, the input will be take from the standard input. \n\n`{{input}}` will describes the input file given to the `run` function. You can use a the `{{output}}` description to specify output file. Be carrefull to specify the `output_ext` then::\n\n    >>> config = [\n    ...    {\n    ...        'cmd': 'sort -r {{input}} {{output}}',\n    ...        'output_ext': sorted # we need to specify the output extension. Here, the file will be \"file.txt.sorted\"\n    ...    },\n    ...    {\n    ...        'cmd': 'wc -c {{input}}',\n    ...    }\n    ...]\n    >>> Pypit(config).run(file_name='file.txt')\n    '6\\n'\n\nNote that if the file is in another directory, you can specify if with `cwd` argument::\n\n    >>> Pypit(config).run(file_name='file.txt', 'cwd'='/tmp')\n    '6\\n'\n\nFinally, it is possible to take a look at the generated command line via the `cmdline` attribute::\n\n    >>> pypit = Pypit(config)\n    >>> res = pypit.run(file_name='file.txt')\n    >>> pypit.cmdline\n    'sort -r file.txt file.txt.sorted && wc -c file.txt.sorted\n            \nErrors may occure in your pipeline. To debug it and display errors use the `errors` attribute which act like a file::\n\n    >>> pypit.errors.read()\n\nShell script usage\n------------------\n\nPypit package provides a shell commands to execute pypit configuration in yaml format. To do the following example, you have to create a `config.yaml` file::\n\n    - \n        path: /bin\n        shell: true\n        name: echo \"12345\"\n\n    - \n        path: /usr/bin\n        name: wc\n        input: STDIN\n        options: -c\n\n\nthen call the `pypit` programme with the config file as argument::\n\n    $ pypit config.yaml\n    6\n\nIf you build your config to handle dynamic file, you can pass those file in arguments::\n\n    -\n        path: /usr/bin\n        name: sort\n        input: STDIN\n        options: -r\n    -\n        path: /usr/bin\n        name: wc\n        input: STDIN\n        options: -l\n\n    $ pypit config.yaml file.txt\n    6\n\n\nVersion\n-------\n\nv0.2.2\n~~~~~~\n\n * add errors handle\n\nv0.2.1\n~~~~~~\n\n * fix issue when with utf-8 options\n\nv0.2\n~~~~\n\n * add dynamic file input support",
