pyeff 0.1.2

Small Python lib, User friendly API for daily python code.

pyeff

a small python library, which include user friendly api, includes fs, json, yaml, logger, and so on.

Install

pip install pyeff

module: pyeff.fs

all API in pyeff.fs:

• remove remove file, files or dir
• copy copy source file or dir to dest file or dir
• move move source file or dir to dest file or dir
• search search file dir in source dir
• ensure remove dir if exists and create new
• current_dir find current dir by file path, like current_dir(__file__)
• listdir list sub path in source dir, filter by extensions, sort and return abs path

API: pyeff.fs.remove

• remove(path, mode='all', patterns=[])
• option mode 'ignore', 'include', 'all', default is 'all'

example-1：

from pyeff.fs import remove, copy

# test remove
remove('./build')
assert not os.path.exists('./build')

remove("./build/data_1_copytree_to_be_remove")
assert not os.path.exists("./build/data_1_copytree_to_be_remove/test.md")

copy("./test/data_1","./build/data_1_copytree_to_be_remove", 
            dirs_exist_ok=False)
remove("./build/data_1_copytree_to_be_remove/test.md")
assert not os.path.exists("./build/data_1_copytree_to_be_remove/test.md")
assert os.path.exists("./build/data_1_copytree_to_be_remove/test.txt")

example-2

from pyeff.fs import remove, copy

# test remove with incldue mode
copy("./test/data_1","./build/data_1_copytree_to_be_remove_2", 
          dirs_exist_ok=False)
remove("./build/data_1_copytree_to_be_remove_2", 
        mode="include", 
        patterns=['*.md'])
assert not os.path.exists("./build/data_1_copytree_to_be_remove_2/test.md")
assert os.path.exists("./build/data_1_copytree_to_be_remove_2/test.txt")

example-3

from pyeff.fs import remove, copy

# test remove with ignore mode
remove("./build/data_1_copytree_to_be_remove_2", 
        mode="ignore",
        patterns=['*.md'])
assert not os.path.exists("./build/data_1_copytree_to_be_remove_2/test.txt")

API: pyeff.fs.copy

• copy(src, dst, mode='all', patterns=None, dirs_exist_ok=False, follow_symlinks: bool = True, copy_metadata=False)
• option mode 'ignore', 'include', 'all', default is 'all'

example:

from pyeff.fs import remove, copy

assert os.path.exists("./build/data_1_copytree_ignore/test.md")
assert not os.path.exists("./build/data_1_copytree_ignore/test.txt")

# test copytree include
copy("./test/data_1","./build/data_1_copytree_include", 
            mode='include', 
            patterns=['*.txt'], 
            dirs_exist_ok=True)
assert os.path.exists("./build/data_1_copytree_include")
assert not os.path.exists("./build/data_1_copytree_include/test.md")
assert os.path.exists("./build/data_1_copytree_include/test.txt")

API: pyeff.fs.move

• move(src, dst, mode='all', patterns=None)
• option modes 'ignore', 'include', 'all', default is 'all'

example-1:

from pyeff.fs import move

assert not os.path.exists('./build/data_1_move_source_0/sub_2/test.txt')
assert not os.path.exists('./build/data_1_move_source_0/sub_2/test.md')
