FlightCrew, the epub validator

Valloric · 10-02-2010, 04:32 PM

I've just released FlightCrew, an open source epub validator. I've written a thorough introduction on the Sigil dev blog, so there's little point in repeating myself here. Read that if you want to know more.

It sounds very interesting, as I am not an epub expert, I just know what I like and try to get there with as little hassle as possible. Thank you very much!

I doubt they will have any more updates on EPUBCheck 1.x, but they have begun preliminary work on EPUBCheck3.

FlightCrew sounds like a great program. I'll use it before I bother with EPUBCheck.

Do four sentences on a wiki page that amount to "we should make something" constitute "preliminary work"? If that's true, I'm starting preliminary work on a space shuttle tomorrow.

Seriously though, FlightCrew will have support for epub 3.0 when it's out and when people start caring about it. The latter will probably come much later than the former though.

Good point, but I would not expect them to be very far along on EPUBCheck3 before they determine what is going to be in EPUB3.

I looked at the code page for EPUBCheck1. It looks like they are working on 1.06. Still I wouldn't expect any major changes to their code until they really start work on EPUBCheck3. All the more reason to use FlightCrew.

AFAIK the only thing coming in epubcheck 1.06 will be a check for unmanifested files. FlightCrew already does most of this by reporting files that are in use but not in the manifest. A "pure" unmanifested files check in FC is forthcoming. It's a fairly simple feature.

Excellent! There you have issues #1 and #2

I tried it on a few files that had not been through Sigil.. Lots of Red seen

Opened them in Sigil, made a tiny change and Saved. Most were gone on the next check.

Request for those files that just "Pass". Some sort of "Last Status" that clears away as soon as Go is pressed or the file name is changed. (Did it run??)

I wonder, since epubcheck is open source, why did you decide to write FlightCrew from scratch, and not just fix epubcheck?

Freeshadow · 10-03-2010, 07:01 PM

as far as i understood val was more than unhappy with the part producing the errmsg in epubcheck, so maybe it would have been far too much work rewriting the existing stuff than starting over.

Valloric, thanks for making FlightCrew available.

The GUI works as advertised, but I can't figure how to invoke the CLI version. From the project site docs, it suggests that the GUI version includes the CLI.

How do I invoke the CLI version?

Cool, hopefully the beginning of the end of epubcheck.

epubcheck is written in Java, and thus can't be embedded into Sigil. FlightCrew is in C++, and thus can be. This was the main driving force.

The GUI package includes the CLI, which is a separate application called FlightCrew-cli.

Except on Mac, because I just remembered I forgot to put in the DMG.

Hopefully, yes.

Thank you for this! I tried it out and my ebooks passed the validation without a single error. At first, I was a bit worried because EpubCheck is not sufficient enough for validation and I have been using it so far. My books still passed your validation software so it gives me little bit better peace of mind

I'll start to use this program. Keep up the good work and thank you!

my ePubs have an image cover page with structure borrowed from a baen book. Flight Crew reports that the svg element can't sit in one of several tags. It's actually in a body element which is not mentioned in the list.

So either it's not a problem (and it does seem to work) or the error message needs tweaking!

All of my epubs seem to pass apart from that. Mind you, none of them will open properly in Stanza so either there is more to ePub than we know or stanza's more picky...

Thanks for making this!
