262.0. "Changebar breaks up in Bookreader" by CASEE::THOMSON (Richard Thomson) Wed Jan 17 1990 09:11

    Usual apologies if the DIR/TITLE failed to find what is already here
    (especially as this subject sounds very familiar...)

    We have a document using <MARK> <ENDMARK> tags, which works perfectly
    well for PS (heeding all the warnings about not crossing heading and so
    on). But when we look at the BOOKREADER form, in some cases the Change
    bar is "broken up." It starts in the right place, and finishes in the
    right place, but is in three or four pieces. The changebar *is* over a
    couple of subheads, but as I say, this causes no problem in the
    hardcopy version, and the subheads are not where the gaps are. Does
    this sound familiar? Is it just another manifestation of the
    "Changebars are a problem" problem?

    I have tried to create a small file to recreate the problem, but this
    is non-trivial for online destinations: the fragment must contain
    contents, front matter tags etc, needs heads and so on -- such that the
    fragment is no longer what was causing the problem 8*). If the problem
    cannot be solved by intuition/reference to another note, then I will be
    happy to supply the source file complete.

    Regards

    Richard

	Yes, Richard, this is (yet) another manifestation of 'change bars are a real pain, er, problem.' problem. The reason for the gaps is because tex thinks all those chunks are pages and the change bars are breaking across the page boundaries. This can, and will, be fixed at some future date. Thanks, Mary

	.-1> The reason for the gaps is because tex thinks all those chunks are pages .-1> and the change bars are breaking across the page boundaries. That's what I thought, but it still seems a bit odd when you realize that we are only talking about fifteen lines of text altogether, and like I say, the breaks are not only between the subheads, they are between lines and para's too. Like this: \| Beginning of changebar somewhere up here \| TITLE BLURB \| First line first para \| second line first para Para about something else \| still only two lines long Last para in the section \| two lines long would you believe \| NEW TITLE (SUBHEAD AGAIN) \| Here we go again \| end of first para Second para \| second line Last para \| last line NEXT (UN-BARED) TITLE Un-bared para strarts here... It certainly makes what the changebar is flagging a tad ambiguous! Just curious, Richard
262.3	It's a feature of granularity	CLOSET::FITZELL	put nifty saying here	`Thu Jan 18 1990 08:50`	4
	The <P> tag creates a new chunk which maps to what Tex calls a page so at the end of the paragraph/chunk/page you get the break in the bar. Mike
262.4	So far so good	CASEE::THOMSON	Richard Thomson	`Fri Jan 19 1990 03:29`	11
	Ok Mike, I buy that... ...but why doesn't it restart until the second line of the new paragraph? Sorry to thrash this out so, but I know my engineer will ask me the same questions... Regards Richard
262.5		CLOSET::FITZELL	put nifty saying here	`Mon Jan 22 1990 08:35`	5
	That part's a bug; for online the paragraphs get shifted up but the change bars didn't. This'll get fixed in the next version(NOT V12B). MIke
262.6	Now I can RIP	CASEE::THOMSON	Richard Thomson	`Wed Jan 24 1990 09:02`	5
	Ok. That fits. Thanks very much. I look forward to V1.2C! Regards Richard
