The difference between this implementation of grep in python from others

1. Searches for different types of input data without specifying the type

• List[str]
• TextIOWrapper: Opened files
• str: Single-line and multi-line strings
• str: Just file paths like dir/filename.txt

1. Works primarily inside the python code and returns a List[str] type that is convenient for further processing
2. Has an unlimited number of input parameters
3. By default, it works with normal (extended) regular expressions Yes - you can simple write in python code:

pattern = r"hello"
str_variable = "hello world"
list_variable = ["hello there", "general kenobi"]
file_path = "test_file.txt" # File contain: "This is a test file.\nhello from file\nAnother line."
result = grepli(pattern, str_variable, list_variable, file_path)
print(result)

And you get sum result:

['hello world', 'hello there', 'hello from file']

See this test code with this example: https://github.com/linxuil/grepli/blob/main/tests/test_grepli.py#L45

This project is grep function implementation for python. I use this "grepli" function for:

• Analyse log files in tests where i need info from linux
  • tcpdump
  • dmesg
  • journalctl
  • <'etc...'>
• Gateway from files in file system to list type in python if run with dot regex grepli . 'filepath.txt'

Try use python script via cmd without install:

$ cd <'prj_folder'>

[prj_folder]$ TST_MULTILINE_VAR='first tested line
second line test
third line'

[prj_folder]$ /bin/python3 console_scripts/main.py 'foo|text.$' foo_yes 'bar_no' 'text. not last' 'last text.' 'tests/pre_created_file.txt' "${TST_MULTILINE_VAR}"

['foo_yes', 'last text.', 'This is a test text.']

You can install via pip in venv:

# Pull repo
$ REPO_URL='https://github.com/linxuil/grepli'&&\
git clone "${REPO_URL}" 'grepli'&&\
cd grepli

# Install venv if needed
$ sudo apt install python3-venv

# Create and activate venv in directory "venv"
$ VENV_DIR_NAME='venv'&&\
python3 -m venv "${VENV_DIR_NAME}"&&\
source venv/bin/activate

# Install module
$ pip install -e .

# Try use console command
$ grepli '\b\w{4}\b' 'text with 4 letters wods' 'text_test' 'tests/pre_created_file.txt'

This command show output contain:

• One string from input parameters
• Two lines from file tests/pre_created_file.txt

['text with 4 letters wods', 'This is a test text.', 'Text like short life 123.']

Then you need exit from venv

$ deactivate
