Dirtools is a little Python package aimed to provide the following features:
- Exclude/ignore files in a directory, using .gitignore like syntax (unix filename pattern matching).
- Generate a hash for a directory tree in order to check if a directory has been modified.
- Search recursively for all subidirs containing a given filename (all projects directory inside a dir).
- Track changes in a directory over time (without duplicating it or without having direct access to it).
$ pip install dirtools
Dirtools let you exlude files using .gitignore like syntax (unix filename pattern matching), by default
dirtools will look for a
.exclude file at root.
Here is how to check if a file should be excluded:
from dirtools import Dir d = Dir('/path/to/dir', exclude_file='.gitignore') d.is_excluded('/path/to/dir/script.pyc')
The hashdir represent the state of every files in a directory. It compute the hash of the hash of each file recursively.
Here is how to compute the hash of a directory, excluded files ares skipped if any.
from dirtools import Dir d = Dir('/path/to/dir') hashdir = d.hash()
Find directories containing a file
We'll call these directories project,
find_projects will search recursively for subdirectories with a
file_identifier file in it.
from dirtools import Dir d = Dir('/path/to/dir') projects = d.find_projects('.project')
Compress the directory with gzip
Dirtools provides a helper to compress the whole directory (except excluded files/dirs) with gzip.
from dirtools import Dir d = Dir('/path/to/dir') # By default, dirtools will create a temporary file to store the archive for you tmp_archive = d.compress_to() # But you can specify a file archive_path = '/home/thomas/mydir.tgz' d.compress_to(archive_path)
Or if you want to do it manually:
import tarfile from dirtools import Dir d = Dir('/path/to/mydir', exclude_file='.gitignore') with tarfile.open(fileobj=out, mode="w:gz")) as tar: tar.add(filename, arcname=arcname, exclude=d.is_excluded)
Track changes in directories
Dirtools provides an helper
DirState to help tracking changes in a directory over time, without duplicating it or without having direct access to it.
from dirtools import Dir, DirState d = Dir(path) dir_state = DirState(d) state_file = dir_state.to_json() # Later... after some changes dir_state = DirState.from_json(state_file) dir_state2 = DirState(d) changes = dir_state2 - dir_state
All methods/properties exclude files and directories based on patterns in
exclude_file and the
If you need to perform operations on files or directories, you can use
Dir.walk, it works exactly like
os.walk, except it will skip excluded files/directories on the fly.
from dirtools import Dir d = Dir('/path/to/dir') for root, dirs, files in self.walk(): # do something
List all subdirectories of a directory
from dirtools import Dir d = Dir('/path/to/dir') dirs = d.subdirs() myproject_dirs = d.subdirs('myproject_*')
List all files recursively
from dirtools import Dir d = Dir('/path/to/dir') files = d.files() py_files = d.files('*.py')
