Pypit 0.1

Pypit is a Python library for building shell pipeline easily via configuration.<br /><br />The principe is simple: create a configuration which describes a programmes list with all options and your done.<br /><br />Exemple:<br /><br />Let's say we have a file.txt with the following content:<br /><br />HellO<br />Foo<br />BAR<br />Bla<br /><br />The following configuration will sort the file.txt and lower all capitalize chars:<br /><br />>>> config = [<br />... {<br />... "path": "/usr/bin",<br />... "name": "sort",<br />... "input": "file.txt",<br />... "options": "-r",<br />... },<br />... {<br />... "path": "/usr/bin",<br />... "name": "tr",<br />... "input": "STDIN",<br />... "options": "A-Z a-z"<br />... }<br />...]<br /><br />To process this configuration:<br /><br />>>> from pypit import Pypit<br />>>> result = Pypit(config).run()<br />>>> print result<br />hello<br />foo<br />bla<br />bar<br /><br />Explanation<br /><br />path, name are required.<br /><br />you can pass all options and arguments to options.<br /><br />If input is "STDIN", the input will be take from the standard input. If input if a file name, this file will be used as input.<br /><br />If ouput is not defined, the output will be send to the standard output. If output is a file name, the output will be writed to the file.<br /><br />Sometimes, we need to call direclty shell command. To do so, add 'shell' = True to the configuration and pass all options directly to name:<br /><br />>>> config = [<br />... {<br />... "shell": True,<br />... "path": "/bin",<br />... "name": 'echo "12345"',<br />... },<br />... {<br />... "path": "/usr/bin",<br />... "name": "wc",<br />... "input": "STDIN",<br />... "options": "-c"<br />... }<br />...]<br />>>> Pypit(config).run()<br />'6n'<br /><br />Shell script usage<br /><br />Pypit 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:<br /><br />-<br /> path: /bin<br /> shell: true<br /> name: echo "12345"<br /><br />-<br /> path: /usr/bin<br /> name: wc<br /> input: STDIN<br /> options: -c<br /><br />then call the pypit programme with the config file as argument:<br /><br />$ pypit config.yaml<br />6<br /><br />#md5=2cebc606746adb5912b80ad3181b245f
