nx_mobi_chapters_gate.nx source

1// nx_mobi_chapters_gate.nx -- gate MOBI chapter-splitting (rung 2 = a real navigable TOC, not one giant chapter). 2// A 3-chapter MOBI (<mbp:pagebreak> delimited) -> book.json with 3 chapters + 3 TOC entries (titles from <h1>) + 3 3// chap<i>.txt files, EACH holding only its own chapter's text (the split is real, not all-in-one). The zero-JS 4// reader already renders chapters[]/toc[] (EPUB path), so multi-chapter book.json => a working TOC for free. 5// expect_exit: 0 license_tier: ORIGINAL 6import "nx_syscalls.nx" 7 8func gp(s: *u8) -> i64 { var n: i64=0;
