Render exact work in strict ASCII

Format synthetic division

The Algebra helper returns a portable ruled Grid. The terminal renderer keeps the rule and exact values without requiring Unicode box-drawing characters.

Runnable RiXRun cell

.Plugin.Load("terminal-ascii"); division := .Algebra.SyntheticDivision(1, [2, -6, 2, -1]); .terminalAscii.Render(division, {= width=64 }).Get("content");

Snapshot a small plot

The plot remains an ordinary core Graphic. SVG and Canvas can render the same value; this target rasterizes its paths onto a fixed ASCII character grid.

Runnable RiXRun cell

.Plugin.Load("plot"); .Plugin.Load("terminal-ascii"); plot := .plot.Polynomial([1, 0, -1], [-2, 2], {= size=[320,180], samples=81 }); .terminalAscii.Render(plot, {= width=60, height=16 }).Get("content");

Wrap and paginate a narrow report

Truncation remains the deterministic default. Opt into word wrapping and a page height when the terminal should retain all text:

Runnable RiXRun cell

.Plugin.Load("terminal-ascii"); report := .Table( [ {= id="step", label="Step" }, {= id="explanation", label="Explanation" } ], [ [1, "Keep the exact input and state the transformation."], [2, "Show the verified result without replacing it by a Float."] ], {= caption="Exact workflow" } ); rendered := .terminalAscii.Render(report, {= width=32, wrap=:word, pageHeight=10 }); {: rendered.Get("content"), rendered.Get("metadata") };

Every page includes its own --- page i/n --- marker and stays within ten lines. The exact table cells are formatted only at this final renderer boundary.

Render a portable slide deck

Runnable RiXRun cell

.Plugin.Load("terminal-ascii"); deck := .Slides([ .Slide(.Paragraph("The source value remains exact."), "Source"), .Slide(.Paragraph("The ASCII view is deterministic."), "View") ], "Exact arithmetic"); .terminalAscii.Render(deck, {= width=40, wrap=:word }).Get("content");

Slides use printable ASCII headings in the default profile.

Opt into Unicode or color

Capability selection is part of the render request. Unicode mode preserves mathematical text and uses box-drawing characters while remaining free of terminal control sequences:

Runnable RiXRun cell

.Plugin.Load("terminal-ascii"); comparison := .Table( ["measure", "value"], [["café total", "2 × 3"], ["bound", "x ≤ 7"]], {= caption="Métrique" } ); unicode := .terminalAscii.Render(comparison, {= mode=:unicode }); {: unicode.Get("content"), unicode.Get("metadata") };

When the destination explicitly accepts ANSI 16-color escapes, select the color profile. Its metadata makes the presence of control sequences visible:

Runnable RiXRun cell

colored := .terminalAscii.Render(comparison, {= mode=:unicodeColor }); {: colored.Get("content"), colored.Get("metadata") };

Omitting mode always returns strict ASCII, regardless of the host terminal.
