Set-up:

Google API shenanigans

For this program to work you need to create a Google Service Account
Then go to a Common Drive and give it , depending on your usage , the following perms:

• Content Manager -> to only manage files created by the same service account
• Manager -> to manage all files

Giving access

To let the program access your account , please create a valid JWT for it. To do so:

1. Go to Google Console
2. APIs (to do left)
3. Credentials
4. Go to Service Accounts on the lower half
5. Create a service account
6. Click on it
7. Go to keys tab
8. Create a key and download it
9. Rename it to credentials.json and move it to ./res/ to be accessed by the program

Downloading the libraries:

    # if you are on anything that uses pip
    make set-up-win
    # if you are on debian(the system that I developed on)
    make set-up-debian

Usage

The validate command

It is made to process files with the following format:

<DATE>_<TIME>_<FILE_NAME>.<EXTENSION>

To be more precise:

YYYY-MM-DD_HH-MM-SS_FILE.<something>

How to use:

   python3 src/main.py validate -d <drive_id> -f <folder_id> 
   -l <lifetime> -p <date_pattern> -g <glob_expression> -r <regex>

Flags explained:

• -d/--driveId -> specify the target drive that you want the process to run on
• -f/--folderId -> specify the target folder from within a drive
• -l/--lifetime -> set the max lifetime of the files that are not going to be deleted. You can disable lifetime check by setting it 0
• -p/--pattern -> provide a pattern that is going to save files from being delete
  For example: YYYY-MM-15 is going to except files that were created on the 15th day of any month and year
• -r/--regex -> search by regular expression
• -g/--glob -> search by glob expression
• --force -> by default , the CLI asks you to confirm the files that are going to be deleted. By adding this flag , you can now peacefully run this command in your script

Example of a glob expression. Similar to the ones you use grep/find or anything with a file filtering process

# get any file that ends in FII_CODE.zip
*FII_CODE.zip
# gets any file that contains 03-
*03-*
# get any file that starts with 2025
2025*

The config command

Every flag specified above is optional. If a flag is not present , the it will get it's default value from:
./res/config.sh

To see all the variables in the config file , please use the following:
python3 src/main.py config --list

To set a variable from within the terminal, use:

python3 src/main.py config <VAR_1>=<VALUE_1>  <VAR_2>=<VALUE_2> ... 
# you can list as much as you like

Development:

General:

• if you are in ASII and need some features , ask me or request to make you a collaborator
• contact me or Frunza Alexandru if you have a problem with setting up a Service Account
• if you develop on a different system , please add the set-up as a rule in the makefile
• modify the CONFIG_PATH variable in config.py to adjust the default config.sh search path

Coding practices:

• use logging for printing - Tutorial
• use unittest module for testing - Tutorial
• any new external files should be put in the ./res/ directory
