No, the rest of the professional computer industry will agree with DNSB. If the code doesn't do what the specs say it should do, there is a bug. If the application doesn't do what you want, it isn't necessarily a bug. Just you misunderstanding what the application is supposed to do.

I totally agree with DNSB and davidfor, mainly because those have been my words to some customers along the years

Yes, I agree, they both need to be done. Please realize that I did it that way not to prove a point, but to actually clean up problems I missed on the last pass through my library. I did understand that you don't think the checks are accurate, and I appreciate anything that can reduce the number of books I have to check by hand. Actually, I think the replaceable/non-replaceable checks probably are accurate enough, between them I didn't find any false positives of books needing fixing. I just checked, and the calibre SVG cover test is not helpful for this purpose. Too many false positives; about 250 books fail this test, many with hand generated covers made in calibre. (No false negatives -- it found ~600 books all with automatically generated covers.) Last edited by compurandom; 12-25-2017 at 08:26 AM. |

Yes, there's some people who's going to want that functionality added, but there's also people who is not going to want it, and should be a plugin apart from the kepub converter, or at least a check in the plugin you can activate or deactivate,given that it's going to produce random results in some cases.

And no, you can't run them both at the same time. But, you can run one for all the books and the other on the results of the first. Or tag them results of each and look at the combinations. Quote:

It flags a significant portion of my library and almost everything it flagged didn't need fixing. The removable/non-removable tests found 101 books. The svg test found 250 *different* books which didn't have problems. Quote:
Now, if I could search for books without a cover page but with a cover image, then all of *those* I could have just run polish on. This is really the only case that is trivial to fix. |

But, I suppose that you could do the Polish and compare the file size of the original with the new. If they are similar, the extra cover probably wasn't added. If there is a bigger difference, it probably was. Of course, there are probably so many problems with this method that it isn't worth considering. |

A bug is when a program should do something a certain way and doesn't do it. If you expect it to do something different then it does, that does not mean it's a bug. It might or might not be a bug. |

I feel this thread has too much in it that is borderline personal attack with pointless arguments over weather it is a bug or a misfeature or whatever, and I don't need to (or should not) respond to it. I want to keep (my) discussion here constructive.
I just want my epubs fixed or converted in a way that makes them pleasant to read on my kobo while making the smallest number of changes to them possible with the least amount of work on my part. Discussion over weather it is a waste of time or not is pointless, as I've already (regrettably) spent the time, and (gratefully) most of my library is now fixed so I don't have any more test cases left. So, until I either do another bulk import, or find another formatting issue common in a lot of books, or find something else to automate, or find more cases of this problem that were missed somehow, I'm done discussing that side of things. I'd like to keep this constructive. I'd like to continue discussing what features / changes could be made to modify/polish epub and quality check. I just went through the entire thread and made a list of possible features that have been mentioned. I'll keep updating that list until someone has a use for it. If I see anyone step forward to update these plugins, or better, I find time to start looking into it, I'll post my list of mentioned feature requests. (Or I suppose I could start a new thread and post the list at the top of the thread.) Right now, the list is a bit disorganized and should be cleaned up and compared against actual existing features, and I'll add to it if I see anything new mentioned. My next personal frustration is that I have so many epubs and pdfs with missing or badly formed TOCs. The toc editor built into calibre only works on epubs, and for a lot of poorly formed epubs, does not do a good job of autogenerating ToCs -- I have several books (converted to epub) that the autogenerated pdf is about 50% bad links. I've partially written code that will extract metadata from a PDF, import a hand generated TOC, and re-insert that into the pdf. Unfortunately, creating the toc is a bit of a laborious manual process, even if you can 90% copy and paste it from the text of the pdf. It might be interesting to somehow leverage the UI of the existing TOC editor in calibre to assist with this process or design something better. It's an idea I've been kicking around for a while. Also, someone mentioned leveraging existing calibre library features that didn't exist when modify epub / quality check were created. I'd be interested in looking at that, is there a specific API reference somewhere that focuses on epub (or pdf) manipulation? If I do dig into this, that would be a good place to start. |

I know from personal experience there are calibre source .py files full of utilities regarding covers, TOCs, OPFs and much more. You'll find some of them in the same directory as container.py. I think there is a logical structure to the way the calibre source is arranged but unfortunately it doesn't always help me zero in on what I'm looking for. I suspect the fault is all mine ![]() |

In this case, I made a suggestion that you apparently tried and decided didn't work for, but you didn't bother to mention that fact. But, you went on about the other part of my suggestion, the part that I didn't think would be useful, and basically complained about how useless it was. Put yourself in my shoes for a moment. Can you see why I might have been peeved? |
