manga's Issues

Use a function for repeated piece of code

$(echo $link | grep -aob '"' | grep -oE '[0-9]+' | sed "q;d")

is used multiple times. Write a function which takes in argument of $link and and returns desired output.

Write separate parsers for mangareader, mangastream and shonen jump official

The heading says it all :)

Use firefox instead of google chrome for pages.sh

firefox is available on all os' while chrome may not be there, plus firefox has the same alias on all os' and while chrome is different on rpm and deb

Use '-q' instead of '-o log.txt'

It is no use making a log file when we aren't using it.
It is just to hide the output of wget. We can also achieve the same by using the -q argument in wget.

Update the code to support Python3.

To Update the existing code written in python 2.x to support python 3.

downloader.sh: improve "not released" message

Change -> "not released yet" to $manga " is not available at www.mangareader.net"

Some info on where the manga is downloaded from would be great

TSIA :D

PDF display prototype

No step by step guide available

I was looking for Getting Started with Poppler and wasted a lot of time in not looking into the actual documentation itself. The problem is that there is hardly any step by step guide to get started with poppler.

What is poppler?

For people not aware of Poppler; Poppler is basically a very common library I have seen while installing packages in Linux. I hardly had any idea of what it was until I saw that many apps use poppler to display PDFs.

Getting started

1. There are three sets of APIs available for poppler (as given here):
   a. CPP
   b. Glib
   c. qt5
2. The test I have done is using poppler-cpp. So, make sure it(libraries and headers) is installed on your system.
3. Since it is in C++, you need to have a C++ compiler installed. I would be using g++ for this example.
4. Finding and linking specific libraries and headers manually is a hard task. I will be using pkg-config to get that information.
5. The program:

#include <poppler/cpp/poppler-document.h>
#include <poppler/cpp/poppler-image.h>
#include <poppler/cpp/poppler-page-renderer.h>

int main(int argc, char **argv) {
  // argv[1] should have the file you want to read from
  poppler::document *d = poppler::document::load_from_file(argv[1]);

  // This creates the first page in the memory
  poppler::page *p = d->create_page(0);

  // This will create an image off the first page in memory of 200xDPI and 200yDPI
  // You can get further documentation online
  poppler::page_renderer pr;
  poppler::image img = pr.render_page(p, 200, 200);

  // This will save the image from memory to a file
  img.save(argv[2], "png");

  // This will free up the memory
  delete d;

  return 0;
}

6. Compile it using the following command:

g++ `pkg-config --cflags --libs poppler-cpp` x.cpp

7. When running the executable, give two arguments:

./a.out ~/Downloads/pdf/resume.pdf test2.png

While working on this I will be updating about this issue in the comments. If you want you can start a PR since it might take time for me to put up a proper version. I will try my best though.

Unable to open the pdf in other shells (except gnome shell), shows up an error

@pandusonu2 The issue can be resolved if " libgnome2-bin " is installed. So, do we need to mention it in README file or create a separate 'requirements' file for it ?

Update variable names

The variables name right now are pretty random, this bug is to make them the variable names better :) Comment to know more about it 👍

Check the status of favourites

Add option to display the status of favourite titles.

It can display in the form of
<title> <latest chapter release> <date of release>

Use /latest for getting larger output

The current newsteller parses data from the main site, but using /latest gives us larger data.

Update Readme

Read the bash script and update the readme files.

Cannot add multiple favourites.

Cannot add multiple favorites.
Even the manga's which are not yet downloaded gets added to favorites if you fix the code.

Document commands on pages.sh

Basically add comments like:

#Gets the index page of mangareader.net
#Open the index page on Google Chrome

Better newsteller parser

This requires a need of little data structures and good grasp of BASH commands.

The news teller just parses the main page and displays the title and chapter and displays each line. Things which can be done

• Arrange all of them acc. to .fav file
• Parse such that multiple chapters of a title appear in single line instead of multiple lines
• Add a specifier to specify number of releases to be parsed

use one file for user interaction.

just use one file say manga.sh and have all others downloader , fav etc as options.

Fix project structure

Right now it is a single file project and without any proper design pattern.
Need to fix it.

needs support for macOS

Log message:

bash downloader.sh 
Enter Manga name:
one piece
downloader.sh: line 3: ${manga,,}: bad substitution
Enter the chapter range.
Start:
1
End:
1
Downloading page 1 of chapter 1.....
downloader.sh: line 46: $((length-1)): substring expression < 0

Check the expression cited above and fix it.

Fix ReadMe markdown

Fix the read me markdown
Just have to fix the indentation :)

-o tag to specify open after download

In case of multiple chapter download, becomes too much of hassle if over 20 pdf's open within short intervals of time.
Therefore need to add a specifier whether to open the documents after download or not.

.fav file is not automatically created

Make install script and man page

so all the script files can be used as commands from anywhere :D

Needs GUI

The current downloader works totally from the command line. Would be neat to have an interface.
Need mock-ups and software which can be used.

page.sh: Remove un-necessary log message

The log generated by the wget command is un-necessarily printed onto the terminal.
Redirect the output on a log.txt file and remove the file at the end

Check before adding favourites

When you execute 'bash fav.sh', we add fav titles to a hidden .fav file. But we don't check if the title is valid.
So make changes to fav.sh to check if the title is valid or not before adding it .fav

Fails when chap has more than 100 pages

Basically due to the line : https://github.com/pandusonu2/manga/blob/master/downloader.sh#L26

Single line execution

The current downloader displays text before each argument is read. Although it is helpful, it can be done in single line by specific tags.

Stupid to include each manga folder, into gitignore.

It is stupid to add each manga into gitignore file, rather we should just have single folder which would contain all the manga folders and add that to gitignore.

-fo tag to open folder of download rather than the pdf

Should read input tag and make changes to downloader.sh

Write python script of the downloder.sh

The current downloader is highly dependent on bash script. Write the same program in python.
