Struct ConsoleState 

pub struct ConsoleState {
    pub input: Editor,
    pub pending: String,
    pub scrollback: Vec<String>,
    pub history: Vec<String>,
    pub history_cursor: Option<usize>,
}

Pure state for the Console tab.

Fields

input: Editor

The single-line input editor for the current line.

pending: String

Lines of an in-progress multi-line form, joined with \n once a balanced form is assembled. Empty when no form is pending.

scrollback: Vec<String>

The rendered transcript (prompts, inputs, and eval results).

history: Vec<String>

Previously submitted complete forms, oldest first.

history_cursor: Option<usize>

Cursor into history for up/down navigation; None means the cursor sits below the newest entry (i.e. on a fresh line).

Implementations

impl ConsoleState

pub fn new() -> Self

The console input is always an Emacs-style line editor, regardless of the app’s edit mode. The REPL has no vim-normal routing or two-stage Esc, so building it in Vim mode (reachable at runtime via Ctrl-V) would strand it in an unhandled normal mode where motion keys insert literally; pinning Emacs keeps the input always usable.

pub fn take_complete_form(&mut self) -> Option<String>

Consume the current input line. If, together with any pending lines, it forms a balanced nomiscript form, return that complete form string, clear the buffers, and record it in history. An unbalanced (incomplete) form is appended to pending and None is returned, so the caller keeps collecting lines. A blank / whitespace-only candidate yields None without echoing or recording history (a bare Enter must not submit an empty form).

pub fn history_prev(&mut self)

Move the history cursor toward older entries, loading the entry at the new cursor into the input editor. A no-op on empty history; once the cursor reaches the oldest entry it stays there.

pub fn history_next(&mut self)

Move the history cursor toward newer entries, loading the entry into the input editor. Stepping past the newest entry clears the cursor and the input line (a fresh prompt).

pub fn push_scrollback(&mut self, line: impl Into<String>)

Append a line to the scrollback, dropping the oldest lines once the retained count would exceed MAX_SCROLLBACK_LINES.
