Confused about this code

u238110 · 08-03-2014, 02:05 PM

I have an ebook that has spacing at the end of its xhtml documents, for example, in the below example the last word in the document is powder and nwhat follows is what looks like some pretty complicated code, but the way it looks in the output is just a little extra space between the last word and the end of the document. If anybody can shed some insight on it, that would be great.

Depending on what exactly classes calibre8/calibre7/calibre13/calibre30 are, your assumption is correct.

Also, it looks like the paragraphs themselves have spans too. You may want to merge them somehow.

To be perfectly honest, spacing AFTER the very last word of a reflowable document doesn't make a whole lot of sense in the first place.

But without the original document that calibre used to generate that particular code when converting, it's hard to say why it did it the way it did. It has to make the best of whatever it gets handed.

Looks like there are some non-breaking spaces after the last word.
Because they only occur at the end of the document, I don't think they will form a problem. You could just erase them, if they bother you.

They add extra space at the end. Probably a conversion from Word or other editor that does 'paged' media layouts.
In most case: no prob.
In some cases: you might get a blank screen before the start of the next chapter

I used to see that sort of thing when I converted RTF or filtered HTML. Since I switched to converting DOCX the classes I see usually see are .calibre and .calibre1 and .block thru .blocknn (typically < 10).

- not sure it makes much sense in a paged document, most (all ?) printers will auto throw a page at the end of document, some can print a standard 'end of document' page from a different bin loaded with different coloured paper :lol:

Most are dumb and still have to run down to the 'footer' code, even if it is nil

BetterRed · 08-03-2014, 07:12 PM

Even my ancient Decwriter throws a form feed at eof, from memory so did a flexowriter, maybe not an asr33 though :lol:

The FF is not until the footer has been printed. There may be many blank lines till it gets there. then it prints those (even if blank), then does the FF.

This is not a printer limitation, but a Program that needs to accommodate a footer.

BetterRed · 08-03-2014, 07:51 PM

My source code files don't have footers

When I print one of those on my Decwriter it throws a page at eof and it's been doing so since I rescued it from being sent to the dump 30+ years ago - gads its noisy though.

From my investigation of code like this, they are very often lines that are supposed to be at the start of the next chapter. If a conversion of a single file does a split at the headers, then anything that was intended to be at the start of the chapter ends up at the end of the previous chapter file. After a conversion of something like this, I have found the anchor used by the in-line ToC to be at the end of the previous chapter. But this code looks like a separator between the end of one chapter and the start of the next. Or code to push the chapter title down the page.

Thanks for all the input, guys.

I must be the only user who actually prefers about 2-4 blank lines at the end of any chapter/file (or whatever). I find this helpful because, while scrolling down the text, you hit the eof - at the bottom of the screen.

Unfortunately, this makes it hard to be sure that you've reached the actual end of text and not some typo, malformed mark-up, or whatever. So I use the extra space as a means of letting me see that I've come to the end. Then if I start reading the next page/chapter and the flow of words doesn't make sense, I know that there is something odd going on.

And it's not just me having lost my mind or anything.

u238110 · 08-04-2014, 05:51 PM

What's the most orthodox way to add that space, Sabardeyn?

BetterRed · 08-04-2014, 08:22 PM

Wherever possible I terminate all books with The End centred and small caps

I also hacked the Modify PI to put a book jacket at the end of the book.
