How to use

For example, you can inherit your class from FSManager class

from fs_manager import FSManager

class Foo(FSManager, ...):
  FSManager.__init__(self, base_path="/some/base", mode=0o744, temporary=True)
    ...

Or you can just use it as an object

from fs_manager import FSManager

with FSManager(base_path="/tmp/base", mode=0o744, temporary=True) as fsm:
  fsm.mkdir(alias="tom", path="tom_dir", mode=0o744, temporary=True)
  fsm.cd("tom")
  fsm.mkdir("tom_dir")
  fsm.mkfile("jerry", "jerry_file", 0o644, True)
  fsm.ls()
  fsm.up()
  fsm.ls()
  fsm.rm("tom")

Save what you did

from fs_manager import FSManager

with FSManager(base_path="/tmp/base", mode=0o744, temporary=True) as fsm:
  fsm.mkdir(alias="tom", path="tom_dir", mode=0o744, temporary=True)
  fsm.cd("tom")
  fsm.mkdir("tom_dir")
  fsm.mkfile("jerry", "jerry_file", 0o644, True)
  fsm.ls()
  fsm.save_all()

...
shutil.copy("/tmp/base/.fs-structure-full.json", "/tmp/another_base/.fs-structure-full.json")
...

with FSManager(base_path="/tmp/another_base", mode=0o744, temporary=True) as fsm:
  fsm.load_all()

Structure will be saved at root to “.fs-structure-full.json”. But structure saves automatically when temporary=False. So if you initialize from the same directory, structure loads anyway.

Initialize you fs-manager from the directory on your disk

from fs_manager import FSManager

with FSManager(base_path="/tmp/base", mode=0o744, temporary=False) as fsm:
  fsm.snappy(root_binded=True)
  fsm.cd("some/path")

Thus, if root_binded=True your structure will be initialized from one root. In other words, you’ll be able to cd right from the root fs-manager object.

Also you can verify hashsum of files under any prefix like that

from fs_manager import FSManager

with FSManager(base_path="/tmp/base", mode=0o744, temporary=False) as fsm:
  fsm.snappy(root_binded=True)
  fsm.cd("some/path")
  fsm.save_hashsums("sha1")
  ...
  mismatches = fsm.check_hashsums(type="sha1", log_warnings=False)

There is much more inside :)
