Formalize current functionality?

Turtle91 · 03-21-2015, 12:25 AM

Soooo....I'm cleaning up a book with 145000 chapters/files. I make a change - a very simple one that shouldn't be any problem - and when I try and save Sigil pukes and says it can't save because there is some malformed code....somewhere.

I could let Sigil fix it automatically...but I would rather not....who knows what would happen then?? So I go file by file and open them one at a time looking for the red error box in the preview pane. Did I mention there are 145000 chapters??...takes FOREVER. I can't even run a report to see if that would help because of the malformed html.

I've lived with this for a couple years...I took it as my just deserts for making the mistake in the first place...but JUST THIS WEEK I found a way for Sigil to tell me which file actually has the error on it.

"How?" you ask. I select all the files in the text folder then right-click and attempt to link a stylesheet. It doesn't let me do this either, but the error code includes the name of the first file with an error!!

Hallelujah!!

Of course, it only lists one errant file at a time....so my request is: Can we formalize that functionality into an error listing? Something along the lines of the "Report" page but with a list of offending files that could be clicked on to open.

That would make my blundering so much more enjoyable.....

Thanks,

I agree I agree, a few of those error dialogs could use some tweaking.

You could always click on the little checkmark icon as well to "Validate EPUB with Flight Crew".

That would also then tell you which files are malformed, and should be able to point you in the general vicinity of the line number of the errors.

This one makes me chuckle. There is even a column in the "HTML Files" report that says "Well formed", but it is impossible to get into the Reports without all of the files being well formed! So all you would see is a column of "Yes".

I will admit

t0 I having seen this issue more than once and being fustrated that I had to attempt to touch each HTML file in Book view (Trying to goto a bad file in BV will flip over to CV and show the dreaded pink box.

Is it possible to at least RED Color Lines in the File Browser for problem files (the ones that will have pink boxes)

Hi
I think I could throw together a python plugin that would walk the complete set of xhtml files and build up a report of any not well-formed files with a description of at least the first error in the file if one exists. Would this do the trick?

BTW: We have already removed Tidy and will use google's gumbo-parser to auto clean up any not properly formed files in the future. Gumbo implements the true html5 parsing spec and will handle the html exactly like browsers will. Gumbo is basically like Beautiful Soup but written in C and really fast.

When is this being released?

I guess in due time... It will probably be a while because this (and the other changes) will take some time to be implemented correctly and consistently.

or The version of Sigil without Tidy and with Gumbo?

If the former, I will try to drum something up later this week or early next if I get a few free moments.

If the latter, Sigil master already has Tidy gone and Gumbo in place but it is in very rough shape as we have been tearing Xerces out of it,and FlightCrew (will make it a plug-in) and will come with python 3.4 embedded in it when it stabilizes. It will need lots of testing but I would guess within a month or so you may see an alpha or a beta. We have already begun changing the OPF Parser to allow and keep epub3 features.

Take care,

KevinH

JSWolf · 03-22-2015, 09:46 PM

Thanks for the information. It is indeed the latter (Sigil without Tidy).

So with the next Sigil, will it be possible to not have the structure changed?

KevinH · 03-22-2015, 10:01 PM

Hi,
No Tidy, so no playing with your classes, no need to remove duplicate classes, just a really robust parser that tries its best to come up with something useful out of any html soup. Plus we get the inherent benefit of recognizing all html5 tags.

Still lots and lots to do before any release as we also replaced the strict Xml processor Xerces with Gumbo node trees and parsing for all xhtml files.

We are replacing the remainder of Xerces use with pure xml (opf and ncx) with python and lxml. So lots of code had to be rewritten and redesigned and still needs some work. I'm sure lots of new bugs will have to be tracked down and fixed. But if we want to support both epub2 and 3 there was no other way then overhaul the tools Sigil used. This is the first step. Once this is complete we can start adding in support for epub3.

Once Xerces is gone, will Sigil still require sse2 hardware?

Yes. Portions of Qt5, most noticeably WebKit, now require sse2. That particular ship has sailed, I'm afraid.

KevinH · 03-24-2015, 03:11 PM

Hi,

This is now updated to version 0.1.0 which provides the line and column of the last open start tag as well when tag nesting mismatches occur.

Hi Turtle91,

Attached is a quick and dirty Sigil validation plugin that will do a rough (and I mean rough!) sanity check of all xhtml files in an ebook and report back the first nesting error, mismatched attribute quotes, things like that which will prevent it from being parsed by an xml parser. It will also detect basic structure errors.

It is NOT in any way meant to replace Flightcrew or EpubCheck. But it will detect gross errors that would prevent a pure xml parser (without a dtd) from loading it.

Nicely, the gumbo html5 parser would happily eat any of this for lunch and fix it automatically on the fly.

Give it a try and see if it will cut your list of files to worry about down to a manageable level. We can improve it if anyone feels it is useful enough to want something that will do a bit more. But for real validation, you really need epubcheck.

I have attached it. Hope this helps.

Wow, that was fast!!
Thanks again Kevin, I'll give it a whirl and report back!
