Overview

Command-line interface for Fontisan.

This class provides the Thor-based CLI with commands for extracting font information and listing tables. It supports multiple output formats (text, YAML, JSON) and various options for controlling output behavior.

Examples:

Run the info command

Fontisan::Cli.start(['info', 'font.ttf'])

Instance Method Summary collapse

Instance Method Details

#audit(*paths) ⇒ Object

Produce a complete font audit report, or diff two fonts/reports, or summarize a whole library.

Parameters:

  • paths (Array<String>) —

    one path (audit/library), or two paths (--compare)

#convert(font_file) ⇒ Object

Convert a font to a different format using the universal transformation pipeline.

Supported conversions:

  • TTF ↔ OTF: Outline format conversion
  • Type 1 ↔ TTF/OTF: Adobe Type 1 font conversion
  • WOFF/WOFF2: Web font packaging
  • Variable fonts: Automatic variation preservation or instance generation
  • Collections (TTC/OTC/dfont): Preserve mixed TTF+OTF by default, or standardize with --target-format

Web fonts — WOFF vs WOFF2: WOFF uses zlib compression and works on every browser that supports web fonts at all (IE9+, all evergreen browsers). WOFF2 uses Brotli and is ~30% smaller but requires modern browsers (Chrome 36+, Firefox 39+, Safari 12+, Edge 14+). Old browsers cannot decode Brotli, so for legacy support serve WOFF. Tune knobs with --zlib-level / --brotli-quality / --uncompressed (WOFF only) / --transform-tables (WOFF2 only).

Collection Format Support: TTC, OTC, and dfont all support mixed TrueType and OpenType fonts. By default, original font formats are preserved during collection conversion (--target-format preserve). Use --target-format ttf to convert all fonts to TrueType, or --target-format otf to convert all to OpenType/CFF.

Variable Font Operations: The pipeline automatically detects whether variation data can be preserved based on source and target formats. For same outline family (TTF→WOFF or OTF→WOFF2), variation is preserved automatically. For cross-family conversions (TTF↔OTF), an instance is generated unless --preserve-variation is explicitly set.

Instance Generation: Use --coordinates to specify exact axis values (e.g., wght=700,wdth=100) or --instance-index to use a named instance. Individual axis options (--wght, --wdth) are also supported for convenience.

Examples:

Convert TTF to OTF

fontisan convert font.ttf --to otf --output font.otf

Convert Type 1 to OTF

fontisan convert font.pfb --to otf --output font.otf

Convert OTF to Type 1

fontisan convert font.otf --to type1 --output font.pfb

Convert TTC to OTC (preserves mixed formats by default)

fontisan convert family.ttc --to otc --output family.otc

Convert TTC to OTC with all fonts as TrueType

fontisan convert family.ttc --to otc --output family.otc --target-format ttf

Convert TTC to OTC with all fonts as OpenType/CFF

fontisan convert family.ttc --to otc --output family.otc --target-format otf

Generate bold instance at specific coordinates

fontisan convert variable.ttf --to ttf --output bold.ttf --coordinates "wght=700,wdth=100"

Generate bold instance using individual axis options

fontisan convert variable.ttf --to ttf --output bold.ttf --wght 700

Use named instance

fontisan convert variable.ttf --to woff2 --output bold.woff2 --instance-index 0

Force variation preservation (if compatible)

fontisan convert variable.ttf --to woff2 --output variable.woff2 --preserve-variation

Convert without validation

fontisan convert font.ttf --to otf --output font.otf --no-validate

Use named preset

fontisan convert font.pfb --to otf --output font.otf --preset type1_to_modern

Show recommended options for conversion

fontisan convert font.ttf --to otf --show-options

Convert with custom options

fontisan convert font.ttf --to otf --output font.otf --autohint --hinting-mode auto

Parameters:

  • font_file (String) —

    Path to the font file
