Could i open image with for sxiv? or is there way to change it to a config file?

Since curses.newpad() only limited to 32767 lines height, 32768 or more will raise an exception. So currently epy cannot open thick books with single HTML page containing more than 32767 lines.

Unless those books are well structured where entire text is split into multiple smaller HTML pages.

Hello,

I'm BM. A very nice and polite guy.

Nice package.

Feature requests:

1. Disable page turning animation. Perhaps toggle it off with a keypress such as "a". I prefer to have it disabled when I read a lot.

Hello,

Can you create a release in order to allow users to package epy?

Please and thank you.

i usually click my windows to change them on my i3 instead of using keybinds, but clicking to turn page isnt the best ideal for me because i end up accidentially changing the page all the time, when i almost always use arrow keys to change page anyways, i got to thinking may be this would be a good feature to have

is there a way to do it like how ranger does it but for cover pages

I have faced following error message when running Windows Terminal (powershell.exe):

Funniest thing is that it just flashes and then first page of page shows. But navigation is not working. It stuck on this first page.

When running in cmder (cmd.exe) everything is fine.

When changing color, it only affects part of a screen that occupied by characters instead of entire screen.

Hi,

I am looking into the possibility to read books cross devices, and therefore the possibility to export/import bookmarks from a device to another (without transferring the entire book every time).

I can see through your code that you store the bookmark with the function savestate(). That same function creates json.dump() in a file.

My question then, where is that file stored?

Note: I installed your CLI app through pypi.org/pip install, and use it entirely in CLI. In my search through my device file system, epy is compiled. I don't see any json file around.

So I guess my questions are as follow:

• In Dev mode, where is the Json File stored?
• In compiled mode, where is the bookmark/json file stored? Or is it accessible?
• Is it in the pipelines to create some kind of "export my bookmarks" command? (If not, no worries, I'll find a way around)

Beside that query, I congratulate for a job well done!

FIle downloaded directly from the repo (since i have all the prerequisites installed), opened one epub without issues. Then tried this:

$ python3 epy.py -h
Traceback (most recent call last):
  File "epy.py", line 1279, in <module>
    main()
  File "epy.py", line 1183, in main
    hlp = re.search("(\n|.)*(?=\n\nKey)", hlp).group()
AttributeError: 'NoneType' object has no attribute 'group'

More strangely:

$ python3 epy.py --help
Usages:
    epy             read last epub
    epy EPUBFILE    read EPUBFILE
    epy STRINGS     read matched STRINGS from history
    epy NUMBER      read file from history
                    with associated NUMBER

Options:
    -r              print reading history
    -d              dump epub
    -h, --help      print short, long help

Short help breaks, log help gives short help.

Linux Mint 19.1, Python 3.6.9, in case it helps. I also installed epr so i imagine the short and long help are essentially the same, so it's not what you'd call "critical", but still :)

Thanks for the great piece of software!

Is it possible to copy text? I can do that in epr, but it seems like in epy, I can only use the mouse for navigation. I prefer epy's features, but copying text is quite important for me.

First of all i wanna say that i m grateful for that amazing program. I love doing as much as possible in terminal. But is it possible to justify text? Is there any way to this? Thx in advance, keep up the good job!

Hi, I like to read in dark or light color scheme. Currently there is a way to specify colors for the color schemes, but no way to select what color scheme to load while starting epy.

So, what I am asking for is a command like option --theme [dark|light] or a config option "Theme":"dark".

Hi Wustho,

Nice that you have added the bookmark functionality! Neat feature! Also good to see that you are actively developing epy [and not only epr ;)] and willing to share your work!

For a possible future version I would suggest to adjust lines 660&661:

# PROC_COUNTLETTERS.terminate()
PROC_COUNTLETTERS.kill()

into

try:
    PROC_COUNTLETTERS.kill()
except AttributeError:
    PROC_COUNTLETTERS.terminate()

On my setup the first leads to attribute errors (perhaps there are some different versions of multiprocessing python package floating around?; I am using python 3.6.9 on ubuntu 18.04 b.t.w.). As far as I could judge the errors occur when the terminal area resizes. With the try-catch epy works again for me also when resizing the terminal. One could also instead use if hasattr(PROC_COUNTLETTERS,'kill') to get to a "get permission" methodology instead of the "ask forgiveness, not permission" philosophy of try-catch ...

Please feel free to ignore if you disagree ;)

Thanks again and with kind regards,
happy user

Is there any chance for a Windows binary? That would be great!

Thanks a lot

Hello,

I'm BM. A very nice and polite guy.

1. Most of the times when I use epy it doesn't save my current page correctly. Let's say I'm on "page 33" (there are no pages but you know what I mean). Next time when I restart epy I am back on pack 20 again so I have to press the keybutton forward x times. Not sure why this is happening, probably a bug.

2. Random page flag. It would be cool if epy could be opened with an -r flag to open a random page from an epub file. Feature request : )

tried pip3 install --user epy Win 10 in a powershell window.
Seemed to install ok.
Added AppData\Roaming\Python\Python36\Scripts to path

Running epy gives above error

And frankly, Harry Potter fanfiction should be read in en_GB ;).

Also, would it be possible to switch to mimic. It is free (contrary to svox, which cannot go into most Linux distributions) and it has stdin-to-speech function, so no need to fiddle with temporary files. Difference in the pronunciation is minimal.

Just like in vim, it would be nice to be able to send keys to epy on startup. An option like >>epy --keys "<Tab>gg" would open epy with contents page open, and cursor on the first contents line item.

If thats difficult, please add a command line option to specify start screen, >>epy -s contents would start epy and launch contents page (as if <Tab> was entered).

Hi, I was just wondering if there were plans to support OPDS feeds in the future? If not then that's fine, the app is great as is 👍🏾

why am I getting highlight in book, I tried turn it off but it seems no use.. and I can't find any tips on internet.

Version: v2022.2.14

epy loads the epub file, but hangs after the first page.

Problem is in (734-754):

    def get_raw_text(self, content_path: Union[str, ET.Element]) -> str:
        assert isinstance(self.file, zipfile.ZipFile)
        assert isinstance(content_path, str)

        max_tries: Optional[int] = None  # 1 if DEBUG else None

        # use try-except block to catch
        # zlib.error: Error -3 while decompressing data: invalid distance too far back
        # seems like caused by multiprocessing
        tries = 0
        while True:
            try:
                content = self.file.open(content_path).read()
                break
            except Exception as e:
                tries += 1
                if max_tries is not None and tries >= max_tries:
                    raise e

        return content.decode("utf-8")

when it is passed a content_path with value: "OEBPS/../jacket.xhtml"

self.file.open(content_path) errors with There is no item named 'OEBPS/../jacket.xhtml' in the archive"
The try/except catches the error.
max_tries = None
The while loop never exits.

My quick fix has been to set max_tries = 2
and add:

content_path=os.path.relpath(content_path)
after the tries += 1 line.

it uses nano for me by default, which is a good editor but i usually prefer using mousepad, is there a way to change it?

epr on the left & epy on the right.

Used to use epr for a long time, now I found epy. What's the difference?

So I'm positive that my terminal emulator and the font I'm using are capable of bold text, however, it does not appear that it's working in the book I'm reading:

The headings show as bold, but text in the content body that's supposed to be bold is not showing as such. Is there something I'm missing?

Here's the source from that section if it helps:

<p>It’s not immediately clear how the prefix and mask work together to give you all possible IP addresses on a subnet. Looking at the numbers in binary form helps clear it up. The mask marks the bit locations in an IP address that are common to the subnet. For example, here are the binary forms of 10.23.2.0 and 255.255.255.0:</p>

<a id="pro_id00249"/><pre class="programlisting">10.23.2.0:        00001010 00010111 00000010 00000000
            255.255.255.0:    11111111 11111111 11111111 00000000</pre>

<p>Now, let’s use boldface to mark the bit locations in 10.23.2.0 that are 1s in 255.255.255.0:</p>

<a id="pro_id00250"/><pre class="programlisting">10.23.2.0:        <span class="strong"><strong>00001010 00010111 00000010</strong></span> 00000000</pre>

<p>Look at the bits that are <span class="emphasis"><em>not</em></span> in bold. You can set any number of these bits to 1 to get a valid IP address in this subnet, with the exception of all 0s or all 1s.</p>

<p>Putting it all together, you can see how a host with an IP address of 10.23.2.1 and a subnet mask of 255.255.255.0 is on the same subnet as any other computers that have IP addresses beginning with 10.23.2. You can denote this entire subnet as 10.23.2.0/255.255.255.0.</p>
</div>

<div class="sect2" title="9.3.3 Common Subnet Masks and CIDR Notation"><div class="titlepage"><div><div><h2 class="title"><a id="ninedot3dot3_common_subnet_masks_and_cid"/>9.3.3 Common Subnet Masks and CIDR Notation</h2></div>

EDIT: The epub does have some embedded fonts - both of which support bold text as well - however, those are overridden by whatever font is chosen by the terminal. I've also attempted to change my terminal font to those fonts (DejaVu and Ubuntu Mono), and there was no change

When I open a epub or mobi, I get the following error. I have not updated epy in my other machine, this does not happen there. Am using the current version of pip3 while reporting this on my current machine.

Dear developer,

My apologies for posting an issue comment. I don't have an issue, but know of no another place to paste a general comment.

I have used epy.py for a while during Christmas last year and wanted to applaud you for this wonderful script. I am impressed! Very nice lightweight epub reader, indeed!

I agree with your comment that showing the progress in the book has added value. However, for me the progress within a chapter is also very useful, as chapter endings are natural places to pause reading. For myself I have therefore replaced this line of code:

PROGRESSTR = "{}%".format(int(PROGRESS*100))

with this one:

PROGRESSCHAPTER = sum(LOCALPCTG[:y+rows-1]) / float(sum(LOCALPCTG))
PROGRESSTR = "{}%/{}%".format(int(PROGRESSCHAPTER*100),int(PROGRESS*100))

I just wanted to post this comment here in case that the developers also may find the chapter progress a useful feature to have.

Thanks again for sharing your work.

With kind regards,
Grateful user

Hi wustho,

Once again I would like to congratulate you with this wonderful project. Very impressive indeed! For novels epy has by now become my principle epub reader ...

In addition it makes me very happy to see how actively you are maintaining it and adding new features with each release! The "bookmark" feature is a very valuable extension indeed (and I am fond of the dictionary search as well, although it is a bit older I believe)!

On another note: recently I stumbled upon the following code:

<p>paragraph1</p>
<blockquote class="calibre24">
<p>quote1<br class="calibre13"/>quote2</p>
</blockquote>
<p>paragraph2</p>
<p>paragraph3</p>

This is rendered as follows by epy:

paragraph1

    quote1

    quote2

    paragraph2

paragraph3

As can be seen also paragraph2 appears indented. I suppose this is the consequence of the use of the paragraph tag <p> inside the body of the blockquote tag, which results in an additional pass through HTMLtoLines.handle_data(), which in turn appends an extra incremental value to self.idinde that in the final rendering corresponds to the position of paragraph2. To me the easiest solution for this example seems to be to update self.idinde only when the tag encloses actual content, i.e. inside handle_data using:

    elif self.isinde and line:
        self.idinde.add(len(self.text)-1)

With the additional conditional on line the result was rendered as desired (for this example):

paragraph1

    quote1

    quote2

paragraph2

paragraph3

This is a tiny non-essential change, but perhaps you may like to take it along in some future update anyway.

Please feel free to ignore this post if you disagree or if you have a better solution ;)

Cheers,
Happy user

Regex searching does not work with russian keyboard layout:

I cannot imagine that anybody would want this state saved per-document. If anybody wants to change it, then she probably wants it same for all other documents in the same terminal, doesn’t she?

You should probably catch this exception and instead display a relevant error message about an invalid regexp search string.

It's not a critical bug, yet epy seems to lose the current position in the file when crashing like that. Without looking at the code, I can assume it only saves position when exitting gracefully.

Tried to set PageScrollAnimation to False here but it seems something still sets it to True somewhere down the road :) (i.e., I can't turn it off)

This is happening on b43ef4c.

First run exits with only: ERROR: Found no last read file.

I had epy installed previously and didn't have this problem, but since I powerwashed my Chromebook and re-installed epy, all I get when trying to open epubs is this:

and then, when I crash the program with ctrl+c, I get this error message:

so, apparently my error is this:
Keyerror: 'there is no item named 'OEBPS/../titlepage.xhtml' in the archive'

Any ideas?

P.S.: Thanks and congrats on the program! It's literally a sight for my sore eyes.

I had epy installed, but now there are errors that epy-git doesn't exist in the AUR.

What was the reason for removal?

Hello, whenever I open a relatively large epub file, the most current is Linux Command Line and Shell Scripting Bible, I receive an error and and forced to use another epub reader such as Thorium. I have received it for War and Piece in the past as well. I am prevented from scrolling beyond a range of pages.

The help menu doesn't say anything about the dictionary integration. Please put some light on how to do it.

I am currently creating an Alpine package for epr, and would like to do the same for epy. This will require making a package for mobi first, so I already made a similar issue on their repo. The distro's maintainers are not really fond of just building a package from a Git commit reference directly, and would definitely prefer the usual Git tags to denote releases. This allows the package to download the contents of the repo at a specific tag, making it clear which exact version we are downloading, and preventing me from picking for example the wrong commit for a specific version and causing a mess.

Another nice advantage of using Git tags is that it is possible to use the Atom feed GitHub provides for releases to be notified of releases; that way, I know when you make a release, and I can upgrade the package accordingly.

I guess adding a git tag to the .mkpkg file could help with automating this. In the meantime, you can just create a git tag for the last version that was built and sent on PyPI and that would be enough to get me started with the packaging.

This issue combined with the mobi issue could help get Arch users unstuck as well (#41), and the added Git tags can also help them get a epy package, not a epy-git, which could be more stable.

.prc files seems to be same as .mobi and can be supported by adding 2 lines in code in det_ebook_cls(file): segment

    elif MOBISUPPORT and filext == ".prc":
        return Mobi(file)

i have created a PKGBUILD for MPR which is an aur like repo for debian and ubuntu and based. my question is how to ensure that /usr is being populated instead of /usr/local.
heres the current package file tree structure
