file path generator from path patterns (Python)

2010-07-09T19:10:59-07:00

Python recipe 577230 by Trent Mick (cli, files, path, paths, walk). Revision 4.

Provides a _paths_from_path_patterns that will generate a list of paths from a list of path patterns. A "path pattern" can include glob chars. By default it generates a recursive listing of file paths, but: recursion can be turned off, file and/or dir paths can be listed. It supports a list of glob exclusions or inclusions.

This function makes it easy to implement typical "-r|--recursive" and "-x|--exclude" options for command-line scripts that work on given file paths. See example usages below.

Note: I use a leading _ on function names because my typical usage of my recipes is as re-usable internal functions in Python modules.

dealing with directory paths with ~ (Python)

2010-06-16T23:17:20-07:00

Python recipe 577270 by roopeshv (directory, expanding, paths). Revision 2.

Dealing with directory paths which start with ~ which are passed as paramaters, to os module functions.

Here is what I think python doesn't do for me:

>>> import os
# suppose my home = curdir = /home/rv
>>> os.path.abspath('.') 
'/home/rv'

Now if I want to go to folder /home/rv/test if there is no folder by name /home/rv/~/test/

# This is what happens by default.
>>> os.path.abspath('~/test')
'/home/rv/~/test'

>>> os.chdir('/home/rv/some/dir')
# doesn't matter if the resulting path exists or not.
>>> os.path.abspath('~/test')
'home/rv/some/dir/~/test'

This would be more sensible I guess:

# if /home/rv/~/test doesn't exist
>>> os.path.abspath('~/test')
'/home/rv/test'
