nx_sitegen_studio.nx source

1// nx_sitegen_studio.nx -- the sovereign WYSIWYG STUDIO library (no main; the daemon + the gate import it). 2// se_build_site = the /build endpoint logic: take a posted (UNTRUSTED) .site blueprint, parse + build it 3// through the GOVERNED sovereign engine (nx_sitegen_parse + nx_sitegen, which escape every field and refuse 4// non-UX-compliant pages), and return the built HTML in a buffer. This is what the editor's thin JS POSTs to 5// for its live preview -- the build is ALWAYS the sovereign organ, never JS. se_editor_html = serve the 6// editor client (web_assets/_studio/editor.html). license_tier: ORIGINAL 7import "nx_sitegen_parse.nx" 8import "nx_sitegen.nx" 9import "nx_syscalls.nx" 10const K_MAGIC_131072: i64 = 131072 11 12func st_slurp(path: *u8, buf: *u8, cap: i64) -> i64 { 13 let fd: i64 = sys_openat_rd(path) 14 if fd < 0 { return 0 - 1 } 15 var total: i64 = 0 16 var go: i64 = 1 17 while go == 1 { 18 let r: i64 = sys_read(fd, buf + total, cap - total) 19 if r <= 0 { go = 0 } 20 if r > 0 { total = total + r } 21 if total >= cap { go = 0 } 22 } 23 sys_close(fd) 24 return total 25} 26 27// build a posted .site blueprint (blob[0..n)) into out (cap); returns output length, or 0 if the engine 28// REFUSED it (not UX-compliant) so the caller can serve a "refused" message.
