Struct WindowTitle 

pub struct WindowTitle { /* private fields */ }

Keeps the terminal title in step with Trail’s directory, writing only when the title changes.

Implementations

impl WindowTitle

pub fn update( &mut self, out: &mut impl Write, mode: TitleMode, cwd: &Path, ) -> Result<()>

Writes the title for cwd in mode to out if it differs from the one shown, saving the shell’s title first. Switching to TitleMode::Off gives the shell’s title back.

Errors

Any error writing to out.

pub fn forget(&mut self)

Marks the title as needing to be written again — after an editor or shell command has had the terminal and may have set its own.

pub fn restore(&mut self, out: &mut impl Write) -> Result<()>

Gives the title back, if Trail changed it: blanks it, then restores the shell’s title where the terminal kept it (see the module docs).

Errors

Any error writing to out.
