Regex for adding numbers to endnote links in Sigil

[Bright Wing]

Hello all,

I have spent a goodly amount time searching for what I think is a simple solution. So I thought I would crowd source it here:

I need to add the href and id numbers to this string (and 310 like it) to my book using Sigil (0.8.6):

<a id="endnote{INSERT number here}" href="../Text/notes.xhtml#endnotes{INSERT number here}">

What is the Regex for doing so?

Thanks!

There's no incrementing counter function in Sigil's PCRE regex engine. It has to capture the number from the text it matches before it can be inserted into any replace expression. I don't think regex is going to help you here.

You may need to use something like the regex-function feature of calibre's editor to create a custom python routine to create the numbers to add to matched strings.

calibre's manual has an example for using function mode to auto-number sections, you can adapt it to handle endnotes.

Last year I created a throwaway Sigil incrementation plugin that might do the trick. Since I only used it for 2 books, you might want to thoroughly test it with a backup copy first.

Note that since all Sigil plugins require Python, you'll need to install Python 2.7. I'd recommend installing ActivePython 2.7.8.1. (Do not install the 3.4.1.0 version; it's incompatible with this plugin.)

To install the plugin do the following:

0. Install Python 2.7.
1. Select Plugins > Manage Plugins.
2. Click the Auto button after Python 2.7. (You should see a file path.)
3. Click Add Plugin, select the attached .zip file, click Open and OK.

You can select the plugin via Plugins > Edit > AddIDs > Start.
To process all a tags in the epub simply click OK.
To process only a tags with a specific class, enter class in the Attribute box and the name of the class in the Value box.

Thanks Doitsu! The increment function in Calibre was one of the only things pulling me away from Sigil (not that it worked)...

Question: Is this ONLY for <a> tags - or can I designate any element? ie <h2>Chapter [increment]</h2>

...and while I'm being greedy... does it increment in letters, or roman numerals???

[Turtle91]

Oh...I see....

This is what I got with my test:

<h2 id="1" href="../Text/notes.xhtml#endnotes1">Chapter </h2>
<h2 id="2" href="../Text/notes.xhtml#endnotes2">Chapter </h2>
<h2 id="3" href="../Text/notes.xhtml#endnotes3">Chapter </h2>
<h2 id="4" href="../Text/notes.xhtml#endnotes4">Chapter </h2>
<h2 id="5" href="../Text/notes.xhtml#endnotes5">Chapter </h2>
<h2 id="6" href="../Text/notes.xhtml#endnotes6">Chapter </h2>


definitely geared towards endnotes, but it makes it very easy to have a single search/replace to fix!

Thanks again!

The version that I uploaded in the previous post is hard-coded for a tags, however, by deleting one line in the plugin it'll work with all tags because it doesn't add hrefs.

Please use the version that I attached to this post, which you can select via Plugins > Edit > AddIdsAll

(To add incremental ids to headings simply enter the heading tag in the first box, e.g. h1.)

Very Nice! Thanks again!

<h2 id="1">Chapter </h2>
<h2 id="2">Chapter </h2>
<h2 id="3">Chapter </h2>
<h2 id="4">Chapter </h2>
<h2 id="5">Chapter </h2>
<h2 id="6">Chapter </h2>

Thank you, Doitsu,

I am thrilled with your plugin suggestion, but when i seek to add the .zip file from your download, it tells me that it is not a valid Sigil plugin, despite installing, as per your instructions exactly, the python file. I am using Sigil .0.8.6 on macbook pro... could that be the problem?

Help!

This usually only happens, if you rename the zip file or try to install the unpacked zip file.
I tested it on Linux and Windows machines without any problems.
If you downloaded the zip file under a different name or renamed it afterwards, please rename it back to AddIDs.zip and try to install it again. If it still doesn't work it might be an OSX build issue.

BTW, I uploaded a slightly updated plugin in the meantime that fixes a rare bug with empty titles and adds pretty print output.

P.S. If you still can't get it to work check out the Calibre Editor. Apparently, it can increment ids, but I haven't tested it yet.

I think I remember Safari automatically unzipping/opening downloaded zip files at some time or another. If that's what's going on, you probably need to figure out how to make it stop doing that. Otherwise, it's probably one of the things Doitsu mentioned.

If you create the text in Word, using its footnote function, you'll find that Calibre will convert the docx to epub very efficiently, with functioning footnote links. You can then move it to Sigil for further work if you wish.

You can also use my Word add-in. It will also convert your notes correctly and you can choose to have them either at the end of a chapter or at the end of the book.
