Struct Options 

pub struct Options {
    pub wrap: bool,
    pub tab_width: usize,
}

The settings shared by every idet frontend, stored as one line per option under $XDG_CONFIG_HOME/idet/options.conf.

Editors read them at startup and write them back the moment one changes. Two editors running at once each keep their own copy, and the last one to change an option is the one whose value survives on disk.

Fields

wrap: bool

Whether a line too long for the window continues on the next screen row rather than running off the side. The text on disk is untouched either way.

tab_width: usize

How many spaces one indentation step adds or removes.

Implementations

impl Options

pub fn load() -> Self

Reads the options file, falling back to the defaults for anything it does not name and for a file that is missing or unreadable.

pub fn save(&self) -> Result<()>

Writes the options back to their file, creating the directory if it is not there yet.

Errors

Fails when the config directory cannot be determined or written to.

pub fn path() -> Option<PathBuf>

Where the options are stored, or None when the environment names neither a config directory nor a home directory.

pub fn indent(&self) -> String

One indentation step as the spaces it inserts.
