2 * xhtml backend for Halibut
3 * (initial implementation by James Aylett)
7 * +++ doesn't handle non-breaking hyphens. Not sure how to yet.
8 * +++ entity names (from a file -- ideally supply normal SGML files)
9 * +++ configuration directive to file split where the current layout
10 * code wouldn't. Needs changes to _ponder_layout() and _do_paras(),
15 * +++ biblio/index references target the nearest section marker, rather
16 * than having a dedicated target themselves. In large bibliographies
17 * this will cause problems. (The solution is to fake up a response
18 * from xhtml_find_section(), probably linking it into the sections
19 * chain just in case we need it again, and to make freeing it up
20 * easier.) docsrc.pl used to work as we do, however, and SGT agrees that
21 * this is acceptable for now.
22 * +++ can't cope with leaf-level == 0. It's all to do with the
23 * top-level file not being normal, probably not even having a valid
24 * section level, and stuff like that. I question whether this is an
25 * issue, frankly; small manuals that fit on one page should probably
26 * not be written in halibut at all.

356 * Ignoring file splitting, we have three choices with each new section:

366 * Y is the last section we added (currentsect).
367 * If sect is the section we want to add, then:
369 * (1) if sect->level < currentsect->level
370 * (2) if sect->level == currentsect->level
371 * (3) if sect->level > currentsect->level
373 * This requires the constraint that you never skip section numbers
374 * (so you can't have a.b.c.d without all of a, a.b and a.b.c existing).
376 * Note that you _can_ have 1.1.1.1 followed by 1.2 - you can change
377 * more than one level at a time. Lots of asserts, and probably part of
378 * the algorithm here, rely on this being true. (It currently isn't
379 * enforced by halibut, however.)
381 * File splitting makes this harder. For instance, say we added at (3)
382 * above and now need to add another section. We are splitting at level
383 * 2, ie the level of Y. Z is the last section we added:
385 * +-----------------+-----------------+
395 * The (1) case is now split; we need to search upwards to find where
396 * to actually link in. The other two cases remain the same (and will
397 * always be like this).
399 * File splitting makes this harder, however. The decision of whether
400 * to split to a new file is always on the same condition, however (is
401 * the level of this section higher than the leaf_level configuration
404 * Treating the cases backwards:
406 * (3) same file if sect->level > conf.leaf_level, otherwise new file
408 * if in the same file, currentsect->child points to sect
409 * otherwise the linking is done through the file tree (which works
410 * in more or less the same way, ie currentfile->child points to
413 * (2) same file if sect->level > conf.leaf_level, otherwise new file
415 * if in the same file, currentsect->next points to sect
416 * otherwise file linking and currentfile->next points to the new
417 * file (we know that Z must have caused a new file to be created)
419 * (1) same file if sect->level > conf.leaf_level, otherwise new file
421 * this is actually effectively the same case as (2) here,
422 * except that we first have to travel up the sections to figure
423 * out which section this new one will be a sibling of. In doing
424 * so, we may disappear off the top of a file and have to go up
425 * to its parent in the file tree.
