KOReader: a document reader for PDF, DJVU, EPUB, FB2, HTML, ... (GPLv3)

How do I create bookmarks in an epub file using koreader?

[Tx65]

Sometimes I encounter typical OCR mistakes in ebooks (like "1" or "I" instead of "l" and so on), and I'd like to correct them on the fly while reading.

Is this possible with KOReader perchance? Or is there another software for my paperwhite which would let me do this?

1) No, it is a reader, not an editor
2) I do not think so, can't recall reading a posting about one.

x) yup, that is irritating and some ocr conversions are really bad. (iie == the)

Just tap in the upper right corner. A dog-ear will appear as your bookmark. To get to a list of all your bookmarks, swipe with two fingers from right to left.

Allow me to reiterate the dictionary issue. This is important for languages where words may have several forms, e.g. resulting from conjugation of verbs like in German and French.

I am trying to use the Search Books feature in the File Manager of KOReader. I want to search for all pdf/epub/djvu formats. If I give *.pdf or *.epub or *.djvu string in the search window nothing is shown. However, if I just input pdf I get to see all my pdf books. But I get the file not found error if I try to open the pdf file by double clicking on it If I input epub or djvu in the search box nothing is displayed tough there are a number of books in these formats.

Would like to know how to use the search feature for

1. Searching for pdf or epub or djvu books and
2. How to open these books by double clicking on the book name

I'm looking for a reader with special features for learning foreign languages.

For example the reader might show 2 books at once on a split screen (for example: top half of the screen: Harry Potter in french. Bottom half: Harry Potter in english. One gesture scrolls both books at the same time).
Or it might show the other language version in a pop up window like the "page flip" feature or something like that.

Does KOReader have something like this? Or are there other tools for my paperwhite which might have it?
I'm quite happy with the instant translation of single words and the vocabulary builder, but I think a dual-language book would be even better. (well, there are dual language books available, but those are rare, special books for beginners.)

AFAIK, only some Android and iOS apps offer this feature. For example, Aglona Reader.

However, it's relatively easy to create interlinked bilingual books, if someone has already aligned the source and target segments.

For an example, see my simple French-English Kindle version of the Three Musketeers. (Also available as an ePub.)

Thank you! I've had a look at Aglona Reader, and while it looks pretty cool, I wasn't too excited about doing all text preparations manually.

However, this did point me in the right direction, and after some digging, I've decided that a combination of LF Aligner, notepad++ and Calibre works for me (all freeware) to convert two books without much manual work into one duolingual epub/azw which gives me in one paragraph some french sentences followed by their english translation in light grey.*

I'm still baffled that there are seemingly no apps which just show 2 books at once though. Aglona Reader is nice, but you have to prep the texts manually which might become tedious if they're thousands of pages long. On my computer I can just open two versions of my favourite book and put them side by side on the screen and scroll manually. I've thought there'd surely be solutions to do something like this on a tablet or maybe even ereaders, but this seems not to be the case.


*in case someone is wondering what exactly worked for me:
1. export both pdf files in Acrobat Reader as txts
2. open with notepad++, convert to utf8, do some cleanup with RegEx if neccessary (page# deletion for example)
3. let LF aligner do its thing, output as .txt
4. clean up with notepad++ RegEx again: delete unwanted last part of each line (\tfr-en\r\n -> \r\n), replace tab (\t) between 1st and second column with another character (like |)
5. import txt into calibre, convert into epub or azw.
6. calibre-editor: search and replace "|" with "</p><p class="translated_text">" to get two different paragraph classes (the other one being <p class="calibre1"> for me)so you can change the CSS properties of the french and english sentences individually
7. change text styles as desired in CSS file, for example make the english translations smaller and a lighter color.

All in all it takes about 10 minutes to convert 2 pdfs/whatever into one duolingual epub or azw.

Upon further research, it looks like some files of the 082414 nightly, including progressbar.lua, were not copied correctly to my PW2. Once I recopied everything, all works as expected. Always assume user error until proven otherwise!!

[Left for historical purposes: I'm running the 082114 nightly build on my PW2 but I do not see the chapter marks on the mini progress bar and there does not appear to be an option to turn them on. I'm reading an ePub with a TOC if that helps. Thanks.

Edited to add: I also have "show advanced options" checked in the config menu but that doesn't seem to do anything so maybe the issues are connected.]

Love Koreader, I'm using it almost daily can't live withot it (and K2pdfopt as well)
but I'm a bit worried for this to become bloatware sometime in the future.. I love the idea of plugins since anybody can simply delete the features he doesn't need.
But as I have the old Kindle (1,5 gb) space is always precious for me. Not a programmer myself but please make as much features pluginable as possible - so that the software does not grow to much for those of us who love simplicity and stability over full feature rich suite. Thanks!

@MaxStirner:
So you like plug-ins?
Try KUAL - everything except the menu framework is a plug-in.

Plus, it is designed so that writing new plug-ins is fairly simple.
Many people have written plug-ins,
in fact,
we sort of gave up on trying to keep the "Comprehensive List" of plug-ins up to date.
Have fun.

- - - -

Maybe we should just have a sort prefix for KUAL (plug-in) Buttons?
Then we could give up on that "Comprehensive List".

Yes, very much so.
