Fixed in 5.99.8, using calibre-5.99.8.tar.xz
Thank you.

I am currently writing a plugin based on webengine_Demo_plugin... It does work even if the configuration part is far from being optimal. (noosfere_util that work as a complement to noosfere DB a published metadata plugin )

My intention is to make it available soon so that bugs can be displayed.

When I saw this thread I thought to verify the compatibility... Well it does not work. Back to basic, try to install and use webengine demo... No luck.

I installed the portable version to not interfere with my installed version 5.39... webengine_demo does NOT SHOW anything after asking the url... A process named calibre worker process flashes to live for a very short time when I hit the ok button in the box asking the URL address...

A

Code:

calibre-debug -g

command seems to start the installed version... Frustrating... I am not sure that I have another 64 bits machine (will I need to borrow the machine of my wife???

)

The startup log follow, if usefull:

To run the portable version in debug mode use full paths. For example, I do what you are doing, running V5 installed and V6 as portable. I start V6 using

Code:

"C:\CBH_Data\calibre.git\Calibre-Qt6\Calibre Portable\Calibre\calibre-debug.exe" -g

Of course the path up to "Calibre Portable" will be different for you.

lrpirlet · 03-22-2022, 09:05 AM

Thanks chaley

I DO have a full path in a portable-debugit.bat file...

I probably was too 'square' in writting the above as path\calibre-debug --gui does indeed run calibre 5.99.8...

What I see is that it does uses all the default of the installed calibre...
Including copying the modified code to the default place of the installed calibre...
I guess this is NOT really tied with PyQt6, yet I was surprised

See my commented bat file...

Code:

rem see https://manual.calibre-ebook.com/creating_plugins.html#id14 goto Debugging plugins...
rem click runit from from the directory where the plugin is developed... 
rem this will kill any running calibre, push a new plugin.zip where appropriate and start calibre again in gui debug mode

"P:\000Calibre\Calibre Portable\Calibre\calibre-debug" -s
"P:\000Calibre\Calibre Portable\Calibre\calibre-customize" -b . 

rem calibre-customize -b . copies the plugin to C:\Users\Papa\AppData\Roaming\calibre\plugins not to P:\000Calibre\Calibre Portable\Calibre Settings\plugins

rem START calibre-debug --gui  creates a new cmd windows that executes calibre-debug --gui 
rem this allows killing a running calibre without fumbling all over the places on my too small monitor...
rem START "P:\000Calibre\Calibre Portable\Calibre\calibre-debug" --gui ... that gives windows does not find '--gui' !!! génial !!!

"P:\000Calibre\Calibre Portable\Calibre\calibre-debug" --gui 
rem that works...

But that is ok, I found an old i5-3210M that has enough disk space and W10 64 bits so I will use that... I may need a couple of days to patch it to the latest version of all the programs I use...

However, I confirm that webengine_demo works on calibre 5.39 and NOT on Calibre 5.99.8...

kovidgoyal · 03-22-2022, 01:00 PM

The webengine demo plugin worked fine for me in 5.99.8. Although, thanks to https://github.com/kovidgoyal/calibr...5a8c71de4c3420 hopefully the need to run webengine in separate processes should go away soon.

lrpirlet · 03-22-2022, 04:32 PM

Thanks kovidgoyal

I should have realized that to use a webengine_demo I got such a long time ago is not the best move...

I downloaded a new version that work for me as well as for you...

For the record I had a main.py dated 20-12-03... It was failing on the import, well before my redirected error output would be activated...

Code:

C:\Users\lrp>calibre-debug

Hello

I have been working on porting noosfere_util to Qt6...

I have the following:

When I comment that line, I also have it for QKeySequence.FindPrevious and for QKeySequence.Find. According to the doc, this should be ok under qt6... It is working under qt5...

short code extract

Code:

        #QShortcut(QKeySequence.FindNext, self, activated=next_btn.animateClick)
        #QShortcut(QKeySequence.FindPrevious, self, activated=prev_btn.animateClick)
        QShortcut(QKeySequence(Qt.Key_Escape), self.srch_dsp, activated=self.closed)

You need QKeySequence.StandardKey.FindNext

lrpirlet · 03-24-2022, 05:41 PM

Thanks kovidgoyal

It works with StandardKey... Even better I could find a reference in QT doc (the label of the column is StandardKey so I can tie with 'key' in QKeySequence(QKeySequence::StandardKey key)

To all who maintain kiwidude-based plugins: There is a problem in common_utils.CheckableTableWidgetItem(). The line

Code:

        self.setFlags(Qt.ItemFlags(Qt.ItemIsSelectable | Qt.ItemIsUserCheckable | Qt.ItemIsEnabled ))

should be

Code:

        self.setFlags(Qt.ItemFlag(Qt.ItemIsSelectable | Qt.ItemIsUserCheckable | Qt.ItemIsEnabled ))

Qt.ItemFlags is changed to Qt.ItemFlag

Without the change and assuming you use that widget, you will get the error

Code:

AttributeError: type object 'Qt' has no attribute 'ItemFlags'

EDIT: The change worked on both the beta and 5.41.

In the kiwidude plugins I maintain, only Reading List uses common_utils.CheckableTableWidgetItem(). This issue doesn't affect FavouritesMenu, ViewManager, GenerateCover or ManageSeries. I'll fix it in source, but I'm not going to release new versions of those.

I wouldn't be surprised if CheckableTableWidgetItem was only used in Reading List.

EDIT: FYI, changing Qt.ItemFlags to Qt.ItemFlag works back to Calibre v2.85.1 for me.

Others have added plugin (floods) over time, but Kiwidude sure made a lot that I use regularly.
Thanks for keeping them alive.
(And Thanks to you Kiwidude if you are lurking)

JimmXinu · 05-09-2022, 09:48 AM

I've far from the only one helping out with kiwidude's plugins, but you're welcome.

And I agree; my thanks too, to kiwidude for all the plugins and to everyone keeping them running.

iamagloworm · 05-17-2022, 04:23 AM

I wonder if anyone could have a look at this plugin? davidfor has updated it for python 3, and collects some metadata from FictionDB, but genre, classification and time period are not added to tags, and I want to add age-level as well, ideally to a separate column.

I really appreciate davidfor reviving this plugin and thought some extra support would be welcome.

Thanks!

lrpirlet Connoisseur Posts: 93 Karma: 40 Join Date: Mar 2020 Location: Belgium (sorry, I am from the Walloon side of the country and I speak french only) Device: PW3, Kobo Libra H2O	Thanks chaley I DO have a full path in a portable-debugit.bat file... I probably was too 'square' in writting the above as path\calibre-debug --gui does indeed run calibre 5.99.8... What I see is that it does uses all the default of the installed calibre... Including copying the modified code to the default place of the installed calibre... I guess this is NOT really tied with PyQt6, yet I was surprised See my commented bat file... Code: rem see https://manual.calibre-ebook.com/creating_plugins.html#id14 goto Debugging plugins... rem click runit from from the directory where the plugin is developed... rem this will kill any running calibre, push a new plugin.zip where appropriate and start calibre again in gui debug mode "P:\000Calibre\Calibre Portable\Calibre\calibre-debug" -s "P:\000Calibre\Calibre Portable\Calibre\calibre-customize" -b . rem calibre-customize -b . copies the plugin to C:\Users\Papa\AppData\Roaming\calibre\plugins not to P:\000Calibre\Calibre Portable\Calibre Settings\plugins rem START calibre-debug --gui creates a new cmd windows that executes calibre-debug --gui rem this allows killing a running calibre without fumbling all over the places on my too small monitor... rem START "P:\000Calibre\Calibre Portable\Calibre\calibre-debug" --gui ... that gives windows does not find '--gui' !!! génial !!! "P:\000Calibre\Calibre Portable\Calibre\calibre-debug" --gui rem that works... But that is ok, I found an old i5-3210M that has enough disk space and W10 64 bits so I will use that... I may need a couple of days to patch it to the latest version of all the programs I use... However, I confirm that webengine_demo works on calibre 5.39 and NOT on Calibre 5.99.8...

kovidgoyal creator of calibre Posts: 44,030 Karma: 22669822 Join Date: Oct 2006 Location: Mumbai, India Device: Various	The webengine demo plugin worked fine for me in 5.99.8. Although, thanks to https://github.com/kovidgoyal/calibr...5a8c71de4c3420 hopefully the need to run webengine in separate processes should go away soon.
