Version: 0.1.0 Created: 2026-04-08 Author: Dojo Genesis Purpose: Fine-tune the Pretext typography engine for optimal PDF output across different content types, audiences, and aesthetic goals.
Pretext does one thing exceptionally well: it measures text on a real Canvas surface, then reports exact dimensions. This means every line break, every paragraph spacing, every margin is computed from actual glyph metrics — not CSS approximations. Typography configuration is the lever that controls how this precision manifests in the final PDF.
Each content type has an optimal typography profile:
| Content Type | Body Font | Code Font | Size | Line Height | Max Width |
|---|---|---|---|---|---|
| Prose (default) | Inter | Recursive | 11pt | 1.5 | 468pt (6.5in) |
| Code review | Inter | Recursive MONO=1 | 9pt | 1.3 | 504pt (7in) |
| Chat export | Inter Variable | Recursive | 13pt | 1.45 | 420pt (5.8in) |
| Presentation | Inter | Recursive | 14pt | 1.6 | 432pt (6in) |
| Reference manual | Inter | Recursive | 10pt | 1.4 | 468pt (6.5in) |
The Pretext bridge supports three font families with variable axes:
Inter (body text):
opsz (optical size), wght (weight)Recursive (code):
MONO (monospace), CASL (casual), slnt (slant), wght (weight)MONO=1, CASL=0, slnt=0, wght=400MONO=0, CASL=1, slnt=-15, wght=400Fraunces (display/headings):
SOFT (softness), WONK (wonkiness), opsz (optical size), wght (weight)SOFT=50, WONK=1, opsz=48, wght=700interface PageGeometry {
size: 'letter' | 'a4' | 'legal'; // Default: 'letter'
margins: {
top: number; // Default: 72pt (1in)
right: number; // Default: 72pt
bottom: number; // Default: 72pt
left: number; // Default: 72pt
};
columns: 1 | 2; // Default: 1
headerHeight: number; // Default: 36pt
footerHeight: number; // Default: 36pt
}
Pretext's prepare() and layout() functions take specific parameters:
// One-time per text block
const prepared = pretext.prepare(text, fontDescriptor);
// Fast re-layout at any width
const layout = pretext.layout(prepared, maxWidth, lineHeight);
// Returns: { width, height, lines[] }
Key: the fontDescriptor must match the actual font loaded in the Canvas context. Mismatches cause measurement drift.
After configuration, export a test page and verify:
system-ui differently on macOS. Always specify exact font family names.opsz axes — using body optical size for headings produces thin, fragile letterforms.1.0 line height make indentation guides invisible. Minimum 1.3 for code.Map ADA agent personality traits to typographic choices:
function dispositionToTypography(disposition: Disposition): TypographyConfig {
return {
fontFamily: disposition.tone === 'formal' ? 'Inter' : 'Recursive',
fontSize: mapVerbosity(disposition.verbosity), // verbose → smaller
lineHeight: mapDepth(disposition.depth), // deep → tighter
maxBubbleWidth: mapBrevity(disposition.brevity), // brief → narrower
fontVariationSettings: buildVariations(disposition),
};
}
For dense reference material (API docs, skill catalogs):
{
columns: 2,
fontSize: 9,
lineHeight: 1.3,
margins: { top: 54, right: 54, bottom: 54, left: 54 }
}
Scenario: Configure typography for exporting a Go backend specification as a client-facing PDF.
pdf-export — Main export workflow that consumes typography configuration@chenglou/pretext — Canvas-based typography enginesrc/lib/disposition/typography.tsA TypographyConfig object ready for consumption by the Pretext prepare()/layout() pipeline, plus page geometry settings for the PDF renderer. Concretely: validated font descriptors, line height values per content zone (body/code/headings), page margins in points, and column count. When used with pdf-export, the output becomes embedded in the rendered PDF — font choices and spacing are baked into the byte stream, not post-processable.
Scenario 1 — Client-facing Go spec PDF (mixed prose + code): Content type: prose primary, code secondary. Audience: non-technical client.
Scenario 2 — Dense code review PDF: Content type: code-primary (diff output, function signatures). Audience: senior engineers.
system-ui resolves to different faces in Canvas and DOM contexts. Always pass explicit family names (Inter, Recursive, Fraunces) to fontDescriptor.Inter at 48pt (heading) with opsz=16 (body default) produces thin, fragile letterforms. Set opsz to match intended display size.CASL axis in monospace mode: Setting MONO=1, CASL=1 simultaneously produces undefined intermediate rendering on some PDF engines. Use CASL=0 when MONO=1.system-ui in any Pretext context. Breaks cross-machine reproducibility and causes Canvas/DOM measurement drift. Use explicit font family names.opsz at heading sizes. Using body opsz (14-16) for large headings (24-48pt) produces optically incorrect letterforms. Set opsz to match render size.1.0-1.2, indentation guides and leading dots between columns become invisible. Minimum 1.3 for monospace content.
