Python에서 directory 관련 명령어

가장 간단한 형태의 glob을 이용 wild_card copy(recursive 보장 안됨)

import os
import glob
import shutil
def glob_copy(src, dst, name_pattern="*"):
    if not os.path.exists(dst):
        os.mkdir(dst)
        shutil.copystat(src, dst)
    
    including = glob.glob(os.path.join(src, name_pattern))
    print("including:", including)
    for file in os.listdir(src):
        print("file:", file)
        file = os.path.join(src, file)
        if file in including and os.path.isfile(file):
            shutil.copy(file, dst)

cp --parents 명령어 구현하기

def make_safe_dir(dir):
    if not os.path.exists(dir):
        os.makedirs(dir)


def remove_safe_dir(dir):
    if os.path.isfile(dir) or os.path.exists(dir):
        shutil.rmtree(dir)

        
def cp_parents(cwd, full_file_path, tmpdir):
    dir_diff = full_file_path.replace(cwd, "").split("/")[1:-1]
    file_name = full_file_path.split("/")[-1]
    target_dir = ""
    if len(dir_diff):
        target_dir = os.path.join(*dir_diff)
        make_safe_dir(os.path.join(tmpdir, target_dir))
    shutil.copy(full_file_path, os.path.join(tmpdir, target_dir, file_name))
    
    
with tempfile.TemporaryDirectory() as tmpdir:
    tmpdir = "../tmp_test"
    make_safe_dir(tmpdir)
    # Copy necessary deps
    cwd = os.getcwd()
    for file_wild_card in files:
        for full_file_path in glob.glob(os.path.join(cwd, file_wild_card)):
            cp_parents(cwd, full_file_path, tmpdir)

아래의 이슈를 보면, cp --parents를 구현하려는 시도들이 많이 있다. 위 코드는 내 나름대로 쉬운 방식으로 구현한 코드이다.

std python library의 문제점을 개선한 Copytree 구현체

import os
import shutil
import stat
def copytree(src, dst, symlinks=False, ignore=None):
    if not os.path.exists(dst):
        os.makedirs(dst)
        shutil.copystat(src, dst)
    lst = os.listdir(src)
    if ignore:
        excl = ignore(src, lst)
        lst = [x for x in lst if x not in excl]
    for item in lst:
        s = os.path.join(src, item)
        d = os.path.join(dst, item)
        if symlinks and os.path.islink(s):
            if os.path.lexists(d):
                os.remove(d)
            os.symlink(os.readlink(s), d)
            try:
                st = os.lstat(s)
                mode = stat.S_IMODE(st.st_mode)
                os.lchmod(d, mode)
            except:
                pass  # lchmod not available
        elif os.path.isdir(s):
            copytree(s, d, symlinks, ignore)
        else:
            shutil.copy2(s, d)

Symbolic link 만들기

os.symlink("modules",  "dest/modules"), target_is_directory=True)
