Extract SVG paths from font glyphs on macOS.

./build.sh

Extract SF Symbols by name from SF Pro Text:

./build/bin/glyphsvg heart bold 768 --output=heart.svg

Arguments: <name> <weight> <size>

Weight selects the SF Pro Text font variant. Valid weights: black, bold, heavy, light, medium, regular, semibold, thin, ultralight.

Extract Material Symbols by name from Google's variable fonts. First fetch the fonts and codepoint maps (one-time, not committed to git):

./material/download.sh

Then extract by name:

./build/bin/glyphsvg --material home 256 --output=home.svg
./build/bin/glyphsvg --material=rounded settings bold 256 --output=settings.svg
./build/bin/glyphsvg --material=sharp star 256 --weight=600 --output=./icons/
./build/bin/glyphsvg --material favorite 256 --fill --output=favorite.svg

Arguments: --material[=<style>] <name> [<weight>] <size>

• Style (part of the flag): outlined (default), rounded, sharp.
• Weight is optional. Give an SF Symbols-style name positionally (ultralight, thin, light, regular, medium, semibold, bold, heavy, black) or an explicit numeric value with --weight=<N>. Both map onto the font's wght variation axis (clamped to Material's 100–700 range; heavy/black clamp to 700). Defaults to regular (400).
• Fill via the FILL variation axis: --fill renders the solid variant, or --fill=<0..1> a partial fill. Defaults to outline (0).
• When the output is a directory, the file is named after the symbol (e.g. home.svg).

The tool locates the downloaded data in material/ relative to the executable. Override the location with the GLYPHSVG_MATERIAL_DIR environment variable.

Extract glyphs from any installed font using character input or codepoint:

./build/bin/glyphsvg --font=Helvetica "Hello" 100 --output=./output/
./build/bin/glyphsvg --font=Helvetica U+0041 100 --output=A.svg

Arguments: --font=<name> <characters|codepoint> <size>

Codepoint format: U+XXXX or 0xXXXX

• --output=<path> specifies output file or directory (a trailing / or an existing directory is treated as a directory)
• If output is a directory, each glyph is saved as a separate file. The name is the symbol name in material mode (e.g. home.svg), or the codepoint otherwise (e.g. U+0041.svg)
• With no --output, a single glyph is written to stdout
• When extracting multiple characters, you must specify an output directory
