Add file search by other criteria

[victordomingos]

Add file search by other criteria:

• date last modified;
• name starts with (name prefix);
• name ends with (name suffix);
• name contains;
• extension starts with (extension prefix);
• extension ends with (extension suffix);
• extension contains;
• file size bigger than;
• file size smaller than.

it will be difficult - many filters. can be used: os.stat, glob or pathlib
usually operating systems have tools for searching and sorting files and folders according to the pattern.
here need to think about what tasks we can solve without duplication.

Actually, while there may be some shell utilities that allow this kind of functionality, sometimes its not very intuitive and requires chaining or piping some commands together. The same could be said about a considerable part of our current feature set. Having a unified tool to count and search files by those criteria may be a little less cumbersome. But we would need to build a more readable help system, as discussed in #87 .

date last modified, file size bigger than, file size smaller than.
this can be applied to the list, just add more statistics from os.stat
it will be necessary to change the def show_result_for_search_files().
name starts with (name prefix); name ends with (name suffix); name contains; extension starts with (extension prefix); extension ends with (extension suffix); extension contains;
Here it is possible to make one more group: Search with regex.
with https://docs.python.org/3/library/fnmatch.html

something like this

from count_files.utils.file_handlers import is_hidden_file_or_dir
from typing import Iterable
import os
import fnmatch


def search_files_with_regex(dirpath: str, extension: str, recursive: bool = True,
                            include_hidden: bool = False, case_sensitive: bool = False) -> Iterable[str]:
    filter_files = fnmatch.fnmatchcase if case_sensitive else fnmatch.fnmatch
    for root, dirs, files in os.walk(dirpath):
        files = [os.path.join(root, f) for f in files
                 if os.path.isfile(os.path.join(root, f)) and filter_files(f, extension)]
        for f in files:
            if include_hidden or not is_hidden_file_or_dir(f):
                yield f
        if not recursive:
            break


# all files
a = search_files_with_regex('path', '*', True, True, True)
print(list(a))
# certain files
b = search_files_with_regex('path', '*.py', True, True, True)
print(list(b))
# certain files with case
c = search_files_with_regex('path', '*.PY', True, True, True)
print(list(c))
# certain files with condition
d = search_files_with_regex('path', '*test_*.py', True, True, True)
print(list(d))
# certain file
f = search_files_with_regex('path', 'test.py', True, True, True)
print(list(f))

Regex won't be for every user, but it's a nice addition. We will need to have a few practical examples in documentation.

We will have to establish the CLI arguments for these.
