Config file path

Returns the formatted path to a config file of an app.

pub fn read(appname: &str, file: &str) -> Result<String>

	match Cfg::read(APP_NAME, CONFIG_FILE) {
		Err(_) => paintln!(Colors::YellowBold, "Not found"),
		Ok(x) => println!("\n{x}")
	}

	println!("\n{}\n", "=".repeat(36));

	paint!(Colors::Blue, "Your wallpaper database: ");

		Err(_) => paintln!(Colors::RedBold, "Not found"),
		Ok(x) => println!("\n{x}")
	}

	match Cfg::read("alacritty", "alacritty.toml") {
		Ok(data) => println!("Your alacritty config:\n{}", data),
		Err(_) => paintln!(Colors::Red, "You don't seem to have an alacritty config!"),
	}

	paintln!(Colors::Rgb(129, 69, 231), "But does your terminal support TrueColor?");

pub fn save(appname: &str, file: &str, data: impl AsRef<[u8]>) -> Result<()>

pub fn global_path(appname: &str, file: &str) -> PathBuf

Global config file path

Returns the formatted path to an app’s global config file.

pub fn global_read(appname: &str, file: &str) -> Result<String>

Read global config

Reads the global config file of an app into a String. Will most likely be parsed, e.g. via Serde.

pub fn global_save( appname: &str, file: &str, data: impl AsRef<[u8]> ) -> Result<()>

Save global

Saves to an app’s global config file. Note that this will override the file!
