SongRec/Internal formats/preferences.toml

From Fossplant

The preferences.toml file of SongRec is saved, under Linux, at the ~/.config/songrec/preferences.toml path by default, when using an unsandboxed environment.

It uses the TOML format.

It is written through by the src/core/preferences.rs utility file, which open the path of the preferences file through src/utils/filesystem_operations.rs.

Save location

The location for the preferences.toml file is calculated through the obtain_preferences_file_path function of src/utils/filesystem_operations.rs.

Relevant code: 

use directories::ProjectDirs;

const QUALIFIER: &str = "";
const ORGANIZATION: &str = "SongRec";
const APPLICATION: &str = "SongRec";

static PROJECT_DIRS: LazyLock<ProjectDirs> =
    LazyLock::new(|| ProjectDirs::from(QUALIFIER, ORGANIZATION, APPLICATION).unwrap());

pub fn obtain_preferences_file_path() -> Result<PathBuf, Box<dyn Error>> {
    let mut preferences_file_path = obtain_preferences_directory()?;
    preferences_file_path.push("preferences.toml");
    Ok(preferences_file_path)
}

fn obtain_preferences_directory() -> Result<PathBuf, Box<dyn Error>> {
    let preferences_dir = PROJECT_DIRS.preference_dir();
    if !preferences_dir.exists() {
        create_dir_all(preferences_dir)?;
    }
    Ok(preferences_dir.to_path_buf())
}
