hjkl-buffer-tui

Ratatui Widget adapter for hjkl-buffer.

Provides a single-pass cell renderer [BufferView] that implements ratatui::widgets::Widget. Extracted from hjkl-buffer as part of #162 (Host-trait phase 4) so the agnostic buffer crate carries no ratatui dependency.

Part of the hjkl monorepo — a vim-modal editor in Rust.

Usage

use hjkl_buffer::{Buffer, Viewport, Wrap};
use hjkl_buffer_tui::{BufferView, StyleResolver};
use ratatui::style::Style;

let buf = Buffer::from_str("hello\nworld");
let vp = Viewport { top_row: 0, top_col: 0, width: 80, height: 24, wrap: Wrap::None, text_width: 80, tab_width: 0 };

let view = BufferView {
    buffer: &buf,
    viewport: &vp,
    selection: None,
    resolver: &(|_id: u32| Style::default()),
    cursor_line_bg: Style::default(),
    cursor_column_bg: Style::default(),
    selection_bg: Style::default(),
    cursor_style: Style::default(),
    gutter: None,
    search_bg: Style::default(),
    signs: &[],
    conceals: &[],
    spans: &[],
    search_pattern: None,
    non_text_style: Style::default(),
    diag_overlays: &[],
    colorcolumn_cols: &[],
    colorcolumn_style: Style::default(),
};
// frame.render_widget(view, area);
