rename to epub .... place in path /usr/sbin/epub .... in terminal change permissions of epub

Code: Select all

chmod 755 /usr/sbin/epub

After that you need to right click on an *.epub file/book and 'set run action' 'epub "$@"'

I gave your script a run and it seems to be operating but when I select an ebook it is greyed out and I cannot add it?

Running xenialpet64-7.5
and fossapup64-9.5 does not do any better?

I only tested on fatdog I will test on fossapup then get back to you.

Thanks for reporting

Code in first post is updated after testing on fossapup and fossadog and fatdog.

The problem was that I have 2P installed and so the necessary directories were already created. Also, you don't select an ebook rather a directory with ebooks in it. These are then listed for the user to select which one to view. Any number of books can be opened and viewed each in its own window.

I ran the second script . The startup screen did not have as much in it and the delete book and open directory buttons did nothing .

Hmm, I tried to look for a problem, but can't get a clear picture...there's 2 message boxes obscuring
my vision of your screen capture! :D

Hi

The first gui is preferences you should set the ebook directory there, by selecting 'other' in the directory menu .... make sure that your partition/directory is already mounted.

open directory and delete ... thanks ... i will add the backend code (I overlooked them).

Added 'scratchpad' - this facilitates printing, saving and translating or dictionary lookup of selected text. As I came across words I knew not the meaning of.

Hi

I have been working on epub viewer to enable the book-cover image file display.

Also the script can be used in set run action for .epub files, which means clicking on an *.epub book will open the script directly at book reading.

Also adjusted mochi's code to show .xhtm text.
And ... Now Applying font and colour settings re-opens viewer in place.

The attachment epub2.png is no longer available

basic epub viewer.
views html / xhtml and accompanying .jpg images as well as cover,png.
Option to hide cover image.
eSpeak option and dictionary lookup if trans is installed.

This IS now working as intended! name script epub place in path /usr/sbin/epub; chmod 755 /usr/sbin/epub

It is nice to see the code, but makes it very easy, to not get it all, to make a working program.

Could you please attach to post the actual script file?

The forum will not allow the attachment to a post, as named script file.
But I usually just edit the name of the file and add fake .gz to end of script file name.
That named file, the forum will allow to attach.
Just tell people to remove the .gz from name, to turn it into proper script file.

Max file size for attachments is 512KiB
This script should be less than that as a attached file.

OK

epub.gz
(22.02 KiB) Downloaded 68 times

rename to epub .... copy to /usr/sbin/epub then in terminal

Code: Select all

chmod 755 /usr/sbin/epub

After that you need to right click on an *.epub file/book and 'set run action' 'epub "$@"' ... so that when clicking on an .epub file it opens automatically with epub.

enjoy!

one problem to solve is how to simply resize the cover image, as they vary wildly in size. I dont want to use image magick, pngtopnm doesn't have the feature.

Downloaded and used the epub.gz script file.
Seems to work.

You forgot to tell people to remove the fake .gz from the name.
Also I needed to give the script file exec permissions.

It is best for everyone, if this epub.gz file, gets attached to the first post of this topic.
Keeping that first post, offering the latest info, keeps people from having to look in page after page of posts, to find the latest working version.

You, as original poster, can edit the first post, anytime you want to.

If you change the script, in any way.
Just make a new epub.gz file and attach to first post.
Even give it a version number, in the name, if you want.

Note:
I am running Raspberry Puppy 8.2.1 (Puppy for the Raspberry Pi computers) on a Raspberry Pi 400 computer.
epub is working in it.
So this epub should work in about any Puppy version.

New features implemented.

Per title font, text and background settings saved and applied when re-opening an epub if 'save changes' applied..
Saves and opens book at last opened file/chapter (htm in epub).

Development In progress:
Saving reading position by selecting relevant line of unique text.

I'm working out a search algorithm that will allow saving ebook position. This will be a basic bookmarking feature.

Giorno Stemsee,

I'm very happy to inform you that your basic epub viewer runs with Toutou Linux Slaxen 6.0 (french version of Puppy).

Many thanks to you.

Friendly.

The next release handles epubs with images too, so one can enjoy those pictures. It used yad --image to display them.

Re: basic ePub viewer

Posted: Sat Oct 02, 2021 9:22 pm
by stemsee

This update now lists images beneath text files. Imges will open in seperate yad window.

Also, in cases where the cover picture is too big, simply double click on a list item and click 'noimage' to stop showing cover pictures. Repeat procedure to view cover pictures.

Fixed eSpeak, removed Scratchpad function.

Here is a different method for handling images. They are now listed and displayed in their own yad window. I've encountered subdirectories for text and images so now the find command is used.

This is a fake .gz file so rename by removing .gz
