Create .toml configuration file for Purrgress

[fariosofernando]

Describe the feature:

Improve the backup schedule configuration by using a configuration file (.config.toml) for the user, instead of hard-coding the interval values ​​directly in the code. The idea is to allow the user to define the backup frequency in a more flexible way, by editing the configuration, and then the program can read this configuration to determine the time interval.

Tasks:

1. Create a configuration file ~/.purrgres/.config.toml that contains the time settings.

• Example structure:

[general]
backup_interval = "1day" # Can be "1day", "1month", "7days", etc.

2. In the source code, modify the way to define the backup interval:

• Currently, we have:

let schedule = utils::schedule::Schedule::OneDay; let mut interval = time::interval(schedule.to_duration());

• Override this so that backup_interval is read from the TOML configuration and turned into the appropriate enum.

3. Modify the code so that when the backup process starts, the program reads the configuration file and sets the backup interval based on the stored value.

• Example of how this might be read:

let config_path = utils::path::get_config_path();
let config = toml::de::from_str(&fs::read_to_string(config_path).expect("Failed to read config file"))
.expect("Failed to parse TOML file");

let schedule = match config.intervalo_de_backup.as_str() {
"1day" => utils::schedule::Schedule::OneDay,
"7days" => utils::schedule::Schedule::SevenDays,
"1month" => utils::schedule::Schedule::OneMonth,
_ => utils::schedule::Schedule::OneDay, // Default value
};

4. Create a new command in the CLI to allow the user to set the backup frequency directly, for example:

• Command to set the backup interval:

purrgres --set-interval "7days"

• This command should update the .config.toml file with the new interval value.

5. Test the correct reading and setting of the values ​​and ensure that the change in the configuration file is reflected in the program's behavior.

• This will make the program more flexible and easy to use, allowing the user to customize the backup frequency without having to change the code.
• If necessary, create validations to ensure that the interval value is within the allowed values ​​(e.g. "1day", "7days", etc.).

Explanation:

1. Configuration in the TOML file: The idea is to create a configuration section in the ~/.purrgres/.config.toml file where the user can define the backup interval. This helps to make the configuration process more user-friendly and customizable without modifying the code directly.

2. Reading from file and transforming into enum: When reading the configuration file, the string representing the interval (such as "1day") can be mapped to a value in the Schedule enum (such as Schedule::OneDay). This allows flexibility in changing the behavior of the program.

3. Command to change the configuration: The --set-interval command will allow the user to change the interval configuration directly, without having to edit the TOML file manually.
