ToC renumbering

In toc.ncx, each entry is numbered in sequential order. If one of the entries is deleted, all the entries after that need to be renumbered. Can Sigil do this for us or can it be made to do this for us?

What about Generate TOC from headings?

I don't always have an ncx that exactly matches what would be produced by "Generate TOC from headings." I often build portions of the ncx manually.

So while it's certainly not something that will keep me up nights if it never materializes; the ability to sequentially renumber existing ncx entries (without regenerating the toc from headings) would be a feature that I would giggle with glee about.

Could you describe an example a bit more - before after entries in the TOC, and explain how a heading gets removed?

Its something I can add to the issue log to track.

In addition to modifying Generate TOC to add the ability to select the heading levels to include in the generated TOC, I've though about using regex to search the document for certain patterns, possibly even entries already in TOC, and then allowing you to choose which entries to include. That would allow auto-renumbering, but is a much bigger issue that may not be as useful.

do toc numbers have to be sequential ?

I often delete chunks of an existing toc to remove unwanted pages/ matching toc entires from start/end of books & that seems to have no effect on remainder of book. It doesn't seems to matter if toc numbering starts not at 1 or if a later part is removed.

e.g. this toc now starts at 2 , but book is fine:
<navMap>

<navPoint class="chapter" id="prol_1" playOrder="2">
<navLabel>
<text>Prologue</text>
</navLabel>
<content src="Text/StraightIntoDa_prol_1.html"/>
</navPoint>
<navPoint class="chapter" id="part_1" playOrder="3">
<navLabel>
<text>Munich, 1929</text>
</navLabel>
<content src="Text/StraightIntoDa_part_1.html"/>
</navPoint>.....

this one starts at 105, then goes 1 thru 99, there is no 100.,101,102,103,104.
<navMap>
<navPoint class="chapter" id="cd587276-645c-4638-adde-7410bf5899f5" playOrder="105">
<navLabel>
<text>Cover</text>
</navLabel>
<content src="Text/dummy_split_106.html"/>
</navPoint>
<navPoint class="chapter" id="1f87fc56-2eb2-4723-be6c-bc4bb244aa42" playOrder="1">
<navLabel>
<text>Title Page</text>
</navLabel>
<content src="Text/dummy_split_000.html"/>
</navPoint>

That's not a problem. The problem comes when you go to add entries (that didn't previously exist) to the ncx file manually. If it's first or last you're OK but anywhere in between and you're renumbering large portions.

It's not that headings get removed... it's that I don't always use headings. So when I go to insert entries into the ncx manually... I often have to renumber the play-orders.

Like I said, it's not that big of a deal for me, but it's something I would use if it did exist.

Not always possible without editing the headings. And in some books, there can be more then 50 chapters. That would be a lot of chapters to have to edit just to renumber the ncx file.

If I remember correctly, in the latest ePub 2 spec, the playOrder property is optional, but if present the values must be unique and consecutive. If you have missing or repeated values it is probably easier to remove them all (they have no use that I know of).

I should try removing the playorder and see what FlightCrew does.

I have a working test version of the tox.ncx playOrder renumbering - right click on the toc.ncx file and select Refresh TOC PlayOrder and the toc.ncx navMap gets re-written exactly the same except the playOrder values start at 1 and increment from there. So you can add something in the middle and it'll correct the numbers.

But I do have some questions.

As also mentioned in http://www.mobileread.com/forums/showthread.php?t=75984 I found that the NCX file can also have 2 other types of navigation lists besides the navPoint - navList and pageList. The current Generate TOC From Headings functionality in Sigil does not do anything with navList or pageList, so the renumbering also ignores/deletes these types of lists.

However, I'm wondering if anyone uses navList or pageList? If it is used and it is in a toc.ncx that you renumber, then the navList/pageList entries will be removed. If it is used, possibly/likely to be used, then I can extend the code to rewrite those as well - since they also have playOrder numbers. As far as I can see there is only one set of playOrder numbers used by each section, so if there is some specific interlaced ordering of the elements that was manually created in the file then that would be lost and all navPoints would show up before the navList and the pageList items in the playOrder.

Requiring you to either make ToC by hand, or use traditional Chapter headings really limits artistic license. Hell, we can't even rename the ToC entries anymore in the ToC view. The old Editor, we could rename the entries, incase we wanted the ToC to appear slightly different than how they were at the start of each Chapter. Not only that, but there are legit uses for using Headers but not wanting it to be listed in the ToC.

I don't know, why even use Sigil if we're forced to code more by hand. I've been using Sigil for quite a while, and there are some changes that have made things easier, but other it so much more difficult.

please tell me that's not correct, someone

IF the toc editor has been scrapped in 0.5 I will want to stay on 0.4.2!

it is there in 0.4.2. which I still use.

The ability to edit the NCX file manually has not been changed in v0.5—if that's what you're referring to.

What exactly do you mean the TOC editor has been replaced? What exactly were you doing before, on what version (I haven't used the old versions much so don't know what to compare the new one to).

If there are features that you want, then if, when you ask for them, you provide more details it might help get them implemented.

For instance, it seems like renaming the entry in the TOC is something that people want. At the moment this can be done by editing the toc.ncx file directly. Or if you generate from headings, then you can put a title value in your heading tag to show the title in the toc instead of the text in the heading. And of course in generating headings you can select which ones to include (0.5.0 even includes an extra drop down that lets you select/unselect based on heading level automatically).

I assume, but I'm only guess, that what you want is the ability to select the TOC entry in the active TOC display and to rename it there without going into the toc.ncx file. If so, that's something I can look into. Though it opens the question of whether or not just the toc.ncx file should be updated, or if the element should have its title value changed as well for consistency (which would also keep generate from headings in sync).

<h# class="noshow" title="anything you want"></h#>

where noshow is small or hidden styling.

<h# class="image" title="Still anything you want"><img alt="" class="chapterN" src="../Images/00002.jpg" /></h#>

My favourite is to use a background image and place text (the number) on top,. 1 image file, not 50 = smaller EPUB
