From 858711e78300340b39bf64b52c70a5bebf844547 Mon Sep 17 00:00:00 2001 From: Jeff Emmett Date: Thu, 16 Apr 2026 15:23:49 -0400 Subject: [PATCH 1/2] feat(rpubs): EPUB export + Publish-to-Space hosted URLs MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit - epub-gen.ts: reflowable (markdown → styled xhtml) and fixed-layout (Typst per-page PNGs wrapped as pre-paginated EPUB3). No new deps. - typst-compile.ts: compileDocumentToPages() rasterizes Typst directly to PNG via the CLI (no poppler/mupdf needed). - Persistent publications store at /data/rpubs-publications/{space}/{slug} with public reader page, PDF + EPUB downloads at /{space}/rpubs/publications/{slug}. - Preview/Press step now has quick EPUB download buttons next to PDF. - Publish panel: "Publish to {space}" is now the primary action, showing hosted URL + copy-link after publishing. EPUB variants remain in downloads. - Dockerfile: new PUBS_DIR volume for persistence.
