Struct Session 

pub struct Session { /* private fields */ }

Everything about the current session. We keep track of display settings (metadata, dual pane, second pane as preview). Display hidden files is read from args or set to false by default. Since it’s specific to a tab, it’s not stored here.

Reads its display values from a session file and updates them when modified. The file is stored at crate::common::SESSION_PATH which points to ~/.config/fm/session.yaml. Unreachable or unreadable files are ignored.

Holds settings about display :

• do we display one or two tabs ? Default to true.
• do we display files metadata ? Default to true.
• do we use to second pane to preview files ? Default to false.

Implementations

impl Session

pub fn new(width: u16) -> Self

Creates a new instance of DisplaySettings. Tries to read them from the session file. Use default value if the file can’t be read.

pub fn dual(&self) -> bool

pub fn metadata(&self) -> bool

pub fn preview(&self) -> bool

pub fn display_wide_enough(width: u16) -> bool

True iff the terminal is wide enough to display two panes

pub fn use_dual_tab(&self, width: u16) -> bool

True if we display 2 tabs. It requires two conditions:

1. The display should be wide enough, bigger than crate::io::MIN_WIDTH_FOR_DUAL_PANE.
2. The dual_tab setting must be true.

pub fn set_dual(&mut self, dual: bool)

pub fn toggle_dual(&mut self)

pub fn toggle_metadata(&mut self)

pub fn set_preview(&mut self)

pub fn toggle_preview(&mut self)
