Short module description
Module pd.find present simple way use filesystem to search and read files on it. File system using showed as simple as using ordinal dict:
>>> import pd.find
>>> f=pd.find.file.File("/etc/sysconfig")
>>> f
'/etc/sysconfig'
>>> f.keys()
['harddisk', 'lm_sensors', 'ipw3945d~', 'syscheckerrc', 'mouse']
>>> f['lm_sensors']
'/etc/sysconfig/lm_sensors'
>>> print str(f['lm_sensors'])
# /etc/sysconfig/lm_sensors - Defines modules loaded by
Other important pakage mission is find files by the way similar to command line find utility:
>>> import pd.find
>>> pd.find.find("/etc/sysconfig",lambda x : x.isreg() and x.check_regex(".*rc"))
<generator object at 0xb7cca7cc>
>>> for item in pd.find.find("/etc/sysconfig",lambda x : x.isreg() and x.check_regex(".*rc$")) :
... print item.path
...
/etc/sysconfig/xinitrc
/etc/sysconfig/syscheckerrc

Using pd.find.file.File
Constructor issued as in example above, with one required argument - path to file or directory. There are other arguments:
- dereference
- Follow symlinks (is False by default)
The File object to provide some useful methods and attributes:
- path
- Attribute present absolute file path;
- __str__()
- Method returns file body if it can;
Other attributes do condition check and will be described bellow.
Issue pd.find.find utility
The pd.find.find utility issued to reqursive search files to satisfy some conditions. Utility accept followed arguments:
- path
- Directory path to search begin with;
- condition
- Condition checked on scanned files and directories. If condition satisfy - object yielded by utility;
- precondition
- Condition checked before subdirectory scan. If condition does not satisfy, subdirectory will not be scaned;
- dereference
- On true value of this argument searhing will be followed by symbolic link.
Utility return generator of list object find by them.
Tests provided by File Object
- mtime
- Return modification time
- atime
- Return last access time
- ctime
- Return creation time """ return self.__checktime_(stat.ST_CTIME)
- newer
- Return true if object is more newer then input path
- check_name
- Return true if object name are equal to input name
- check_path
- Return true if object path are equal to input path
- check_path_regex
- Return true if regexp matched object path
- check_regex
- Return true if regexp matched object name
- check_iregex
- Return true if regexp matched object name
- depth
- Return current depth on file tree
- dele
- Delete file by path of current object
- execute
- Frm will be substituted by substring "{}" on path and executed by os.system() call
Ho-ho. Sorry my English :)
