Crate smelt_term 

Pure terminal renderer: double-buffered diff/flush, LayoutTree, Grid, paint_chrome, and half-block-friendly cell primitives. Editor concepts (Window, Buffer, overlays) live in smelt-edit.

Key entry points:

• Compositor::render_with - drive a frame.
• paint_layout_tree - walk a LayoutTree and dispatch leaves.
• flush_diff - emit SGR escapes for a Grid diff.
• Grid / GridSlice - set / put_str (full overwrite; string writes return the clipped end column), put_char / put_str_fg / put_line (preserve bg where applicable).
• TerminalSession - raw-mode/alternate-screen lifecycle guard with suspend support for shell-outs.

Modules

ansi

ANSI helpers for turning SGR-styled transcript text into terminal lines.

compositor

flush

geometry

Viewport geometry primitive shared by grid and layout.

grid

hit

Typed hit-region registry. Hosts push (Rect, payload) pairs during paint and query them on mouse events. Reset between frames.

layout

line

Styled text primitives. Span is a single attribute-uniform run; Line is a sequence of spans for one visual row. Both are data-only; rendering happens via crate::grid::GridSlice::put_line.

session

snapshot

Frame snapshot: a faithful, round-trippable capture of a rendered terminal frame.

surface

Renderer facade: bundles a Compositor, Arc<Theme>, LayoutTree, and terminal size. Use directly for standalone renderers; smelt-edit’s Ui wraps it and adds editor-specific state.

Macros

line

Construct a Line from a list of Into<Span> values. line!["foo", " ", Span::styled("bar", red)]

Structs

Style

Theme

Resolved highlight-group → style map. Theme is materialized state: every group has its final Style baked in. Construct via smelt_tui::theme::compile or hand-build with Theme::set.

Enums

Color

Functions

paint_layout_tree

Walk node against area, paint chrome on containers, and dispatch each resolved leaf rect to paint. Fit constraints use the default NoopSizer (contribute 0); use paint_layout_tree_with to drive content-aware sizing.

paint_layout_tree_with

Like paint_layout_tree but uses sizer to resolve Fit constraints against each leaf’s natural size. Must use the same sizer as the rect resolution that drives hit-testing and viewport setup, so painted rects match.

Type Aliases

PaintDispatch

Per-leaf paint callback: (paint_id, leaf_rect, grid, theme, terminal_size). The renderer calls this for each resolved LayoutTree::Leaf.
