basiomeuspuga / lector Goto Github PK

trying to launch it I get a crash.

python 3.6.3
pyqt 5.7

I haven't used QPainterPath() so not an expert, but looking at the code on that line:
mask = QtGui.QRegion(self.path.toFillPolygon().toPolygon())

toFillPolygon indeed doesn't have any arguments passed to it?

here's the error:

Traceback (most recent call last):

Hello!

Python 3.6.5 on Windows 8.1:

C:\Dev\pyenv\Scripts\python.exe lector\__main__.py

According uname documentation, os.uname is only availiable on Unix systems.

Please fix this.

Hi,

I am trying to build an RPM package. But when building the package, I got this message:

[    9s] This text file contains a shebang or is located in a path dedicated for

[    9s] the file is meant to be an executable script, add the executable bits,
[    9s] otherwise remove the shebang or move the file elsewhere.

From this StackOverflow post https://stackoverflow.com/a/19305076/4699409

The shebang line in any script determines the script's ability to be executed like an standalone executable without typing python beforehand in the terminal or when double clicking it in a file manager (when configured properly).

So maybe it is not very necessary to add SheBang to files that won't be executed directly but only be included. If SheBang is needed, then it requires executable bits, too.

Would love to use this app, all efforts to install after installing dependencies have failed for me.

I'm not sure if this is already planned,but horizontal scrolling and zooming would be something nice to have. As of now, if the image width is too big I can't view the full image.

Currently, each tab in the application view is as large as the title of that book. It will be nice to set a maximum tab width on the interface and append a ... to the title so that more books can be navigated easily.

It will be nice to have drag and drop support in the library view so that a user can simply drop a book on the library to have it added to the library.

When trying to add a book to my library, I get the following error:

Database returned no paths for settings...

This seems to happen most of the time. There have been a couple of times that I managed to actually add books, but they didn't appear even though the library didn't throw an error. Happy to try and debug it.

I think it would be nice to show the % value with the graph or without it.

How did you get sipdistutils installed for Mac.

None of the normal methods work for me.

pip install sip doesn't install sipdistutils

I installed the application from the aur into my desktop. When I launch it gives me this error:
pkg_resources.DistributionNotFound:The 'PyQt5>=5.10.1' distribution was not found and is required by lector
However, I have this package installed already:
sudo pacman -Ss pyqt5

Common PyQt files shared between python-pyqt5 and python2-pyqt5
extra/python-pyqt5 5.10.1-1 [installed]
A set of Python 3.x bindings for the Qt5 toolkit

I don't know if this could be a bug, but if all the options in "sort by" drop down show all the books except the option "Last read", I don't know if this could confusing because only shows read books and not the unread.

Features request:
If I sort it by "Last read" would be nice to show the last read date.
Also in the "table" view doesn't show the "Last read" column for sorting.

How can i unistall LECTOR?

It would be nice if there would be a Flatpak available, there are already many programs that were submitted to Flathub (https://github.com/flathub/flathub/pulls), so I'd suggest to submit it to Flathub.

I like the idea to use icons for functions that are less frequently used, which makes the UI simple and symmetric. So, I make minor modification to the UI with prototype tools. This link shows the dynamic interaction.

Strangely enough, it works fine for the source code for v0.4 downloaded from releases page and those differ only by 1 commit.

I’d love to share this application with my friends, but there appears to be no support for internationalization. Could this be added eventually?

It will be nice to have a vertical list of opened books; like the bookmarks view except that it is for opened books, or a vertical tab listing option so that it is easier to just from book to book and back to the library.

I've tried install the dependencies and I fails in do that by some dependencies like ( sipdistutils ) don't install.

Just wanted to let you know that there is an unofficial Fedora RPM repo for lector at:
https://copr.fedorainfracloud.org/coprs/bugzy/lector/
You can include it in the readme if you wish

In 2018, the choices for desktop app creation seem to be...Electron. Thanks for using Qt and thanks just for creating a cool free/open source software project. Wanted to get some thanks in before you're hit with a ferocious list of real issues ;)

Lector does not render epub documents with the document's inbuilt stylesheets. This is somewhat problematic since it results poorly displayed epubs and in-turn reflects poorly on the application. It will be nice if the default rendering of epubs documents simply applies the styles that comes with the document, then custom css is applied on top for things like changing font size, background, etc.

Whereas this problem may also apply to other supported formats such as mobi. I can only confirm issued with epub files.

Currently, the internal table of contents in an epub document can be viewed in a drop down select-style-menu at the top of of the interface when viewing a document. It will be nice to have a Tree style table of contents appear on the side (similar to the bookmarks display pane and okular)

Hi, I tried a lot, but pdf-support doesn't work. All requirements are installed, I think...

Any hints for me? Thank you!

Would it be possible to integrate this as a channel/plugin to plex (plex.tv?)

It would be the perfect thing for my plex server. It manages everything already tv shows/movies/music only ebook/comic support is missing.
Check this link aswell: https://forums.plex.tv/search?adv=&search=Ebook&title=&author=&cat=all&tags=&discussion_d=1&discussion_question=1&discussion_poll=1&comment_c=1&comment_answer=1&within=1+day&date=
Thousands of people would use it if it would be available as a plex plugin

Please let me know if it is possible and what would need to be done to add it to plex

Please, provide a makefile or .sh script for automating dependency installation in Ubuntu. It's pretty tiring to do it manually

It is nice to have the keyboard bindings for moving back and forward (chapter by chapter/ page by page) but it will help to have previous and next buttons/icons in the GUI perhaps under the book view-port in the middle of the status bar (the same bar where the distraction view toggle is located)

1. Decrease the height of the status bar.
2. How to manage books? like group, star, etc. I can't find a way to make a priority reading list.
3. Smooth the mouse scrolling. It's too slow for epub.
4. Support continual reading mode.
5. Use filename as title insead of "Unknown".

Is there any future plans to enable touch for the UI?

Currently the key bindings for the arrow keys behave the same in the reader view; that is, "left" and "right" arrow keys behave the same as "up" and "down" arrow keys. It will probably work better if the if the "up" and "down" arrow keys are used for scrolling up and down, while the lef and right keys remain the same as they are now.

It's possible to have ctrl + o shortcut to add books?
And up/down keys in the pdf parser?

Thanks for all your work.

On arch I get the following errors after installing through AUR:

Summary: Opening Lector and scanning a directory of ebooks results in scanning pool.py and parser.py failure.

==Steps to reproduce:==

1. Open Lector.
2. Click on cog wheel icon (settings).
3. Select path to scan in the "Library" window.
4. Click "Scan Library"

==Expected Results:==
Books appear in the Library view of Lector

==Actual Results:==
Progress bar displays progress through 100% but nothing appears in library view (even after restart).

==Additional Info:==
The output on the command prompt, which seems to pin-point where the failure occurs is as follows:

Locale: en_US (No translations found)

I have installed lector on arch via trizen -S lector-git
The install was successful, but after running lector in term, I get this error.
Any idea what's wrong?

I'm having trouble installing lector. At the third step of README.md

From either build and install or running main.py, getting this error. Pretty sure all dependencies are met. Do I need to set a path to my ebooks before opening the app?

With the latest git version installed via the AUR package on Manjaro Linux, I have an issue that I can reproduce with the following steps:

1. Open an epub book, such as A Byte of Python.
2. Type the word "Python" into the search bar, hit Enter.
3. Nothing happens, even when I'm on a page/chapter that contains the word "Python".
