Exporting

Press Cmd+E, or use File → Export. Unsaved masters are saved first, so what you export is what is on disk.

Runebender looks for build-fontc.sh or build.sh beside your source, then in each parent directory, stopping at the repository root. If it finds one, it runs that script and reports where the output landed.

This is deliberate. A project that already builds a specific way should keep building that way, and the editor should not be a second opinion about how your font is made. Google Fonts projects usually have such a script already.

The script runs with a repaired PATH, so a project .venv, cargo binaries, and Homebrew are all reachable even when the application was launched from the Dock.

With no build script, Runebender compiles the source with fontc and writes the result next to it.

Install fontc if you do not have it.

Runebender looks for fontc on your PATH, then in ~/.cargo/bin. If neither has it, export stops and says so.

Names in public.postscriptNames are applied on export, so working names in your source do not have to be the names that ship.

Glyph → Export Glyph as SVG writes the current glyph as an SVG file beside the source. It is for a drawing you want outside the font, not part of the font build.
