Coolreader and FBreader Bugs and Wishlist

[Manolo]

As we have threads about PDFReader I think a thread about Coolreader and FBreader bug reports and wishlist is needed too. Firmware updates thread are long and this is related to i62HD and M92
So, in no specific order we have:

A.-Coolreader

1.-Fonts
(Same bugs in both CR and Fbreader)

1a)Unable to switch to external fonts located in the folder "Fonts" either in the internal user memory partition or external microSD card.
Fonts can only be added to the hidden system partition.
Unofficial Workaround: you can use OTFM to move fonts, but it isn't the desirable way to add fonts and you can broke things with OTFM!!
Official fix: none

1b) It's limited the number of fonts (I think the maximum number is 25).
Unofficial Workaround: none
Official fix: none

1c) Problems in accent characters (á, ê, ï, ù ...) or others special characters in some font families
(strictly is a font issue not a CR/FBR issue)
Unofficial Workaround: don't use those fonts and use others that doesn't have the problem (Bitstream, Dejavu ...) or even delete them with OTFM

2.- Hyphenation:
2a) Bad Hyphenation: Hypenation in CR is "tied" to a specific hyphenation file: "Russian_EnUS_hyphen_ (Alan). Pdb"
Any book open in another language does not show a correct hyphenation.
Moreover, there is no way to choose Pdb file for the preferred language of reading.
Unofficial Workaround: Rename your language hyphen file to
"Russian_EnUS_hyphen_ (Alan). Pdb" with OTFM in the hidden system partition
(user rfog talk about that in this forum some months ago and no improvement done in official firmware)
or edit CR3.ini file
Official fix: none

IMO users should have the option to choose their hypen file and/or CR should choose automatically the right language hypen file according to the document language.
(It's what FBReader do with usr\share\onyx_reader\zlibrary\hyphenationPatterns .zip)

2b) User would also be able to switch on/off hypen
Unofficial Workaround: edit cr3.ini as stated by pkobo
https://www.mobileread.com/forums/sho...43&postcount=7
(but user shouldn't´t meddle with config files editing, this is a ereader not a sysadmin tool simulator!)
Official fix: none

3.-Dictionaries lookup problems
Dictionary lookup doesn't always work as it should in CR.
(as user yayo reported in i62 firmware updates thread)
When you double tap on a word to open the dictionary lookup sometimes what happens is that you just turn the page or that you turn the page AND open the dictionary. And the highlight isn't precise, the darker area doesn't just encompass the tapped word but it extends upward, so that it almost touches the word above the one you mean to highlight/lookup in the dict.
Dictionaries in CR work much worse than in FBReader or PDFReader.
Unofficial Workaround: none (apart from using FBReader or PDFReader of course)
Official fix: some improvement in firmware from April 2013

4.-CR in our Boox is an "old" release.
It's release 3.0.51-28 (October 2011 in Coolreader download web) while I have seen 3.0.57-15 (may 2012) in an unofficial firmware for Jinke Hanlin V3
(and 3.1 in Android but I'm not sure if 3.1 releases are available for Linux non-Android).
I suppose some CR3 bugs should be patched in current releases and perhaps a few features added.
Of course I'm talking about CR3 for Linux not CR3 for Android.
Why can't Onyx (or its distributors) update CR3 to newer releases of CR3 for Linux? Perhaps is there any problem with Boox SDK and newer CR doesn't compile?
Unofficial Workaround: none (unless somebody install Onyx SDK and compile it)
Official fix: none

5.- It does not updates the "Recent documents" and "Recent reading" lists.
Unofficial Workaround: none (apart from using FBReader or PDFReader of course)
Official fix: fixed in April 2013 release

6.- CSS bug in EPUB

https://www.mobileread.com/forums/sho....php?p=2011208
(thanks to Mono and Tuxor)
Unofficial Workaround: Copying epub.css file from the repository as stated in
https://www.mobileread.com/forums/sho...08&postcount=2
Official fix: 1.8 firmware uses the same epub.css that Tuxor recommended, but it isn't perfect

7.- Bookmarks percentage bug
(thanks pkobo)
CoolReader shows strange numbers in the bookmarks list, for instance "1090" when current book has 540 pages only. This confuses users. Actually this is percent and should be displayed as 10.90%
To fix it, onyx devs should replace their code:

        int pos = list[i]->getPercent();
        QString str(tr("%1"));
        str = str.arg(pos);
        QStandardItem *page = new QStandardItem(str);

with:

QStandardItem *page = new QStandardItem(crpercent(list[i]->getPercent()));

in the src/cr3/cr3_onyx/src/mainwindow.cpp

B.-FBReader

1.-Images in ePub
Not shown images in ePub, mainly cover book images.
Unofficial Workaround: none (apart from using CR or PDFReader of course)
Official fix: none

2.-New FBReader releases
As in CR our FBreader release is old (It has been said here that is 0.10.3 from 2009!! If that is correct there is an stable release 0.12.10 from 2010). I know that FBreader for Linux development was stalled for two years and only updated Android versions were released. But since july 2012 we have the new beta branch 0.99 for Linux (not-Android) and last update is 0.99.4 from November 2012.
Has anyone in Onyx (or its distributors) checked how new FBReader works in our ereaders? I know is a beta release but 0.10.3 or 0.12.10 doesn't seems to be a 1.0 release either isn't it?
Unofficial Workaround: none (unless somebody install Onyx SDK and compile it)
Official fix: none

3.-Fonts problems
See Coolreader section as both have same behavior with fonts.

C.-OTHER/WHISLIST

1.-While not strictly a CR o FBReader issue I want to add to whislist is option to choose engine for MOBI, RTF, TXT, just the same way we can do in EPUB.
Yes I know can be done with OTFM.

2.-Wish: more options including quotation and more highlight options, options to disable included CSS styles in EPUB (as CR for Android do), ....

3.-Zoom options to images in CR

D.-COMIC READING BUGS
1.-It doesn't save the last page opened with cbz files
(thanks luki)
Unofficial Workaround: none
Official fix: none

2.- Cbr/cbz must be browsed using the keys on the left side.
It would be better allow use the M92 joystick to turn page like can be done with all the other formats.
(Thanks underscore)

E.-DJVU BUG
1.-Some DJVU doesn't open again, but them can be openbed if remaned or moved
https://www.mobileread.com/forums/sho...3&postcount=41
(thanks edmon)
Unofficial Workaround: none
Official fix: none

Of course I will be grateful if you contribute bugs, solutions and wishes.

This seems to be already fixed in the sources so I assume it will be in the next FW update.

I guess this limitation comes from menu design and it is not easy to fix.

There should be no problems with compilation. I guess onyx just doesn't have enough resources to accomplish all the tasks they have.

[fraylocus]

Totally agree with the list of bugs reported by the partner Manolo.

For the most are old and have been reported in various threads of this Forum and other discussion where Onyx products, as lectoreselectronicos.com

Only lack the technical staff of Onyx deign meet our requests.

The bug of the separation of words would have been very easy to fix adding lines of code written by RFoG and published in this forum.
With this simple solution, prevails hyphenation code we copy in the path: \ cr3 \ hyph internal memory of the reader.
But nothing has been done, from which it follows lack of interest.
The work has focused exclusively on the PDFReader, which also needs to improve its management of epub.
It is time for the other engines are cared reading.
The wide clientele Onyx readers need and demand.

greetings

[Pooh_]

One more Coolreader's bug: it does not updates the "Recent documents" and "Recent reading" lists.

[fraylocus]

An interesting feature, for FBReader CoolReader and would be a switch hyphenation, to display the internal styles of books in. Epub.

[pkbo]

fraylocus I'm not sure I've got your idea correctly. There is setting in the cr3.ini file that controls if CoolReader should display styles embedded in the epub:

crengine.doc.embedded.styles.enabled=0

There is no gui setting for it in the onyx version but you can edit the ini file. It is disabled in the above sample. You need to set it to 1 in order to enable. Regarding hyphenation - to turn hyphenation off you need to add (modify) in the cr3.in file the 'crengine.hyphenation.directory' property like below:

crengine.hyphenation.directory=@none

To turn on algorithmic hyphenation the property should look like:

crengine.hyphenation.directory=@algorithm

To use spanish hyphenation dictionary you should set it to

crengine.hyphenation.directory=Spanish_hyphen_(Alan).pdb

It would have to check what you said.

But anyway, the normal user must read only provide a simple and accessible interface rather than proposing a code tangling.
And that is the manufacturer & distributor work.

A greeting.

Sure, I agree.

In addition, displays captions with internal metadata, but is set to not remove

[Isles8008]

Create an option, like on the tablet version, to turn off hyphenation. Ther-
e is nothi-
ng more ann-
oying than having te-
n hyphenated lines on every page.

I will be overjoyed when this update comes out!

I love my Onyx Boox M92.

[slex]

I would like to have highlighting and highlight export.
