Quickstart

>>> from reconfigure.configs import FSTabConfig
>>> from reconfigure.items.fstab import FilesystemData
>>>
>>> config = FSTabConfig(path='/etc/fstab')
>>> config.load()
>>> print config.tree
{
    "filesystems": [
        {
            "passno": "0",
            "device": "proc",
            "mountpoint": "/proc",
            "freq": "0",
            "type": "proc",
            "options": "nodev,noexec,nosuid"
        },
        {
            "passno": "1",
            "device": "UUID=dfccef1e-d46c-45b8-969d-51391898c55e",
            "mountpoint": "/",
            "freq": "0",
            "type": "ext4",
            "options": "errors=remount-ro"
        }
    ]
}
>>> tmpfs = FilesystemData()
>>> tmpfs.mountpoint = '/srv/cache'
>>> tmpfs.type = 'tmpfs'
>>> tmpfs.device = 'none'
>>> config.tree.filesystems.append(tmpfs)
>>> config.save()
>>> quit()
$ cat /etc/fstab
proc    /proc   proc    nodev,noexec,nosuid     0       0
UUID=dfccef1e-d46c-45b8-969d-51391898c55e / ext4 errors=remount-ro 0 1
none    /srv/cache      tmpfs   none    0       0

This is actually a shortcut to:

>>> from reconfigure.parsers import SSVParser
>>> from reconfigure.builders import BoundBuilder
>>> from reconfigure.items.fstab import FSTabData
>>> content = open('/etc/fstab').read()
>>> syntax_tree = SSVParser().parse(content)
>>> syntax_tree
<reconfigure.nodes.RootNode object at 0x7f1319eeec50>
>>> print syntax_tree
(None)
        (line)
                (token)
                        value = proc
                (token)
                        value = /proc
                (token)
                        value = proc
                (token)
                        value = nodev,noexec,nosuid
                (token)
                        value = 0
                (token)
                        value = 0
        (line)
                (token)
                        value = UUID=83810b56-ef4b-44de-85c8-58dc589aef48
                (token)
                        value = /
                (token)
                        value = ext4
                (token)
                        value = errors=remount-ro
                (token)
                        value = 0
                (token)
                        value = 1

>>> builder = BoundBuilder(FSTabData)
>>> data_tree = builder.build(syntax_tree)
>>> print data_tree
{
    "filesystems": [
        {
            "passno": "0",
            "device": "proc",
            "mountpoint": "/proc",
            "freq": "0",
            "type": "proc",
            "options": "nodev,noexec,nosuid"
        },
        {
            "passno": "1",
            "device": "UUID=83810b56-ef4b-44de-85c8-58dc589aef48",
            "mountpoint": "/",
            "freq": "0",
            "type": "ext4",
            "options": "errors=remount-ro"
        }
    ]
}

Parsers and builders can be paired in almost any possible combination.

Reconfigure can be easily extended with your own parsers and builders - read the docs!
